Extreme Engineering - MegaProjects - SF-Oakland Bay Bridge & Big Dig

One of my favorite things to do on internet is to search for future projects being planned or execute across the world. I like reading about major infrastructure projects like new bridges, tunnels, buildings etc. being planned; how will they defy challenges imposed by nature and how they are continually testing the limits of human ingenuity. I am totally mesmerized by the skill and innovative mind of engineers who not only just think of such ideas, but also have the tenacity and courage to actually implement them. I watched two episodes of Extreme Engineering recently. One was on the Eastern replacement of San-Francisco Oakland Bay Bridge on the western end of America, while the other was on the eastern end - the historic Big Dig.

The San Francisco Bay is one of the most talked about, innovative, lively place in the world. With its pleasant climate, superb landscapes and rich biodiversity, it attracts people from all around the world. Moreover, it is the place of Silicon Valley , the birth place of most of the IT companies in the world. I really want to go there once and explore the natural beauty of the place. The San-Francisco bay area is a populated region with may major cities and metropolitan areas - San Francisco, San Jose, Oakland, Santa Clara etc.

San Francisco Bay
These cities are served by a series of bridges that interconnect them and allow transportation between them. The Golden Gate Bridge is the most famous out of them. In fact it is one of the most famous bridges on the planet and even the most photographed bridge in the world according to some. But, the main workhorse of this area is the San-Francisco -Oakland Bay Area bridge which carries the most traffic. In 1989 an earthquake rattled the city which sits upon some of the most devious earthquake faults in US. The earthquake damaged the bridge severely and it was sure to the city planners that the bridge won't be able to overcome the next earthquake. Thus, the planning began for the reconstruction of eastern section of bridge.

  5. Dumbarton Bridge

The Construction of bridge started in 2002 and it was completed in 2013. It is currently the widest bridge in the world with 10 lanes of Interstate going through and lanes for pedestrians and cycling. The project was the biggest project in history of California with the estimated budget of $6.4 billion. The challenge was to build one of the most heavily used bridges in US (240,000 vehicles per day) which was earthquake proof. The bridge was designed radically with tripod designed shafts 300 m deep in basin. The bridge was constructed along the older bridge. The bridge was opened to public in September 2013 to people and is believed to function for next 150 years. Now, that the bridge has been completed, the task of demolishing the older bridge is on the way. As per planning the older bridge will be gone by 2016.

Our next project took place in the opposite side of US, the metropolis of Boston based on the edge of Atlantic Ocean. The city of Boston has a rich history with the roots of US independence starting from here. When the interstates were being built, due to poor planning Interstate 93 was built to cross in between the city's downtown. The expressway was built to support 75000 vehicles a day, but by 1990's it was carrying 200, 000 vehicles a day. The situation was very bad, there were long traffic jams. Experts predicted that if no solution is found, the crisis will lead to traffic jams of 16 hours per day by 2010. The city officials started looking for a solution when a contractor proposed a radical and bold solution - The Big Dig.

Traffic before Big Dig
The main problem with the city were:
  • Heavily congested Interstate 93 passing through the city's core downtown
  • Heavily used Interstate 90 - Massachusetts Turnpike which was used to go to Logan airport and passed through Boston
  • These two expressways intersected in Boston Downtown.
To solve these issues, designers envisioned taking the whole I-93 underground and removing the elevated expressway. They planned to replace the expressway with series of green spaces and parks. Moreover, they decided to extend I-90 Massachusetts Turnpike to a tunnel under harbor to directly link it to Logan Airport.

Traffic after Big Dig
This project was very challenging and required building tunnels under the downtown and harbor without disrupting thousands of commuters using it daily. To increase the problems, the area of downtown was a landfill and was crowded with utilities and subway. The engineers had to sort out all the utilities and then design tunnels at a more depth due to presence of subways. As if this was not enough, engineers found that the soil was not string enough to support the digging of tunnels. Engineers brainstormed on the issue a lot, and later found the solution in Tokyo Japan, where they inject a mixture of concrete to strengthen the soil. There were so many more problems with this mega project like moving these massive pieces to place in these crowded city lined with low bridges. But, in the end after construction stopped in 2007, the impossible task was done. The Big was completed after a massive expenditure cost of $22 billion as per Boston Globe.
The whole time it took to complete Big Dig from planning in 1982 to completion in 2007 took a massive 25 years. People have called it the most expensive highway project in US. But, to engineers Big Dig will be always one of the most perfect examples of extreme engineering.

Few Lines by Javed Akhtar

These lines moved me so much that I especially wrote them in Hindi.

ज्ब ज्ब दर्द का बदल छाया 
ज्ब गम का साया लहराया
ज्ब आँसू पॅल्को तक आया
ज्ब यह तन्हा दिल घबराया
हमने दिल को यह समझाया
दिल आख़िर तू क्यू रोता है

दुनिया में यूही होता है
यह जो गहरे सन्नाटे है
वक़्त ने सबको ही बाट्‍टे है
थोडा गम है सबका हिस्सा
थोड़ी धूप है सबका हिस्सा
आँख तेरी बेकार ही न्म है
हर पल एक नया मौसम है
क्यो तू ऐसे पल खोता है
दिल आख़िर तू क्यो रोता है

American TV Shows: What's Next?

I was not that much into TV, until I had the rendezvous with Big Bang Theory in 2009. I had my engineering exam in 2 days and my friend (don't know if he still deserves it) gave me 2 full seasons of it. I started with the first episode, just to take some rest and from then begin my interest in BBT. I still remember that I did not picked up my book, until I finished all the episodes of both the seasons (16 + 23). Yes, it was so addictive. After that I have watched every episode of it and even now I am waiting for the next episode to be aired on 24th April 2014.

The next TV Show that I watched was Supernatural, it was recommended by my friend Soumen in 2013 I guess, when I was in Accenture. Unlike BBT, Supernatural lost its charm after some time. I just watched first 4 seasons. In supernatural some episodes were really good and bound me with the series, but most of the episodes were boring. Usually the trend was that first few and last few episodes were best and it was the in between shit that was unbearable.

The third TV show I saw was Suits, a different kind of TV show based on a legal drama. It was really good in beginning and I started binge-watching it. But with season 3, it also started to bore. There was nothing jaw-dropping in it. The lavish life of Harvey Specter and the charm of NY started to fade away and it took whole of my willpower to stop the season in middle; for greater good, I stopped the season 3 at episode 8.

Now, I am thinking, which TV show to watch next? House of Cards, Game of Thrones or 24. Hmm, tough choice. I am inclined towards Game of Thrones, but it is like that special series, which I want to watch with my full devotion. I don't want to watch it in parts or with a gap. Now, I am having holidays and I am in Toronto and thus, I don't get much time to spend on my laptop. So, it is difficult to convince myself to start Game of Thrones. The gore and adult scenes make that choice more tougher. Lets see what I decide. (Fingers crossed.)

Microsoft's 2014 Build Conference : Nothing Surprising and Totally Boring

Today is April 2, 2014; I was waiting from a long time for this day to come. The reason was the start of Microsoft's Build 2014 event started today at Moscone Center in San Francisco. Finally Microsoft will unveil Windows Phone 8.1. I was so excited to see what they are gonna offer new in the world of mobile ecosystems. The main reason was that since I bought Lumia 720, I was attracted to Windows Phone platform; I liked its smooth and innovative live tiles interface. In the world continuously filled with chaos of Apple Vs Android, Windows Phone seemed a peaceful alternative. Rather than going with their clumsy Windows Mobile OS, Microsoft VP Terry Myerson decided they needed a new OS built from scratch to battle Android and iOS.

Windows Phone is an amazing operating system, it offers some really nice features like Data Sense, Live Tiles and a much better and easier to use interface. I was so much involved in this ecosystem , that I used to browse the WPCentral app multiple times in a day to quench my thirst of recent developments. But now, as its been 7 months and the early fever has started to cool off. Moreover, the Windows Phone 8.1 did not surprised as much as I had expected. There were no groundbreaking new innovations, just few tinkering and new features announced to offset demand for similar features in other platforms. The main features released today were Action Center and Cortana both of which are in response to other similar features in iOS and Android. While Apple released Siri in October 2011 and Android released Google Now in July 2012; Microsoft launched Cortana today around 30 months after Apple. This shows that Microsoft is not launching any innovative feature, but just following the lead of Apple. The other groundbreaking feature as mentioned by Microsoft was Action Center, which is nothing but just a modified version of Notification Center and Control Center Combined.

Actually I felt the conference, so boring that I was working really hard to keep my self awake while trying to listen to Joe Belfiore. Completely useless and boring. I still remember how amazed I was to see Scott Forstall's demo of Siri on iOS6. It seemed like a breakthrough. I realized that Apple not just posses the skill to think and develop innovative products and services, but they also have the coolest presentation skills I have ever seen from a company. Everything is in sync, rehearsed and perfect; when they first launched Siri, it worked flawlessly on stage, while Cortana got stuck multiple times. I don't know how it will perform in real time.

Now, I am believe I understand what Steve Jobs meant when he said, "The only problem with Microsoft is they just have no taste. They have absolutely no taste. And I don't mean that in a small way, I mean that in a big way, in the sense that they don't think of original ideas, and they don't bring much culture into their products".

New Beginnings

Its been a long time, that I have written something on this blog. The last post was in November 2013; so much has changed in those last 5 months. I have left my job in Accenture and moved back to education. I am currently doing my Masters degree in Computer Science from University of Windsor. I had already thought about this time before; actually dreamed and that too lot of it. But, now when I have come here, its a complete new experience. Someone has said it right only that the grass on the other side always looks greener. Sometimes, it looks like normal and I don't feel that how big a change it is, but sometimes I am myself astounded by how far have I come; Delhi -> Windsor = 11853 km.

Before, boarding the flight I used to think, how colossal is this distance and how will I be able to cross such a distance. But, actually I never felt it; it feels like all this is a dream only. How else can a person travel from one corner of world to another so quickly. In ancient times, this was a voyage of a lifetime, it would take months to cover this distance. Even though I enjoy a scientific temper, I am sometimes astounded by the wonders of science and technology. I still sometimes feel how is this all possible; I spent the whole of my life in India and now suddenly I am in a new place with new people, a different kind of culture and even  a different type of climate. Yet when I look closely the fog of these differences starts to clear and I see how many Indians are here.

Canada is a textbook example of multiculturalism, especially if you are in a major city like Toronto. Most of the people I saw were of different ethnic groups, there were lot of Indians, Chinese, Koreans, Persians, Black people. When I reached Brampton, I was completely in a state of shock, the whole area was settled by Indians especially Punjabi's. It was like a Little Punjab here. I was so excited, to see the new landscape, new kind of homes, roads, and those exits on the highway. Wow. It was cold out there and the roads were empty unlike India where they are full of people, whenever you go out in day. The next morning, I woke up early and saw outside the window, there was snow everywhere, the streets were full of it. It was like someone put a white blanket over the landscape. I was feeling so happy; for the first time in my life, I was seeing fresh snow.

This is a completely new beginning for me here, I have start my life afresh from scratch. I have to make new friends, learn new customs/traditions. Basically, I have to relearn most of the things I know again from a new perspective. Every change is a challenge, but if we overcome the challenge and accept it, it gives so many fresh opportunities to us which wouldn't have been possible without it. The game is starting again, and I need to do a lot in a short amount of time.

Space Race 1: The Race to Put the first Man in Space‏

The Space Race is one of the most interesting stories of human history. It is a captivating story full with surprises and setbacks covering a period of time which witnessed one of the highest level of technological growth in human history. Space Race took place in the third quarter of 20th century between the two superpowers of the post-world war II world – Russia and USA. The main motive of this race was to establish technological supremacy in the space, the next frontier and to further solidify its position at earth.
The beginnings of human exploration of space actually started in the beginning of 20th century when an American scientist Robert Goddard created world’s first liquid fueled rocket. Another German engineer Wernher von Braun, impressed by the works of Goddard, started working on rockets as a medium to explore space. Germany at that time was under the influence of Nazi party. Nazi leadership recognized the genius of Von Braun and gave him grants to create a powerful rocket that can offer payloads at greater distances to be used in war. During this time Von Braun worked on the V-2; world’s first long range ballistic missile.  After Germany’s defeat in World War II, Russia and US became interested in the V2 rocket and  a hunt for rocket parts and scientists who worked on the program started between both. Britain also launched Operation Backfire to gather as much resources and information about this new weapon of Germans. During the war, hundreds of rockets were shipped back to US and USSR research labs where they were analyzed. America got a huge victory when von Braun and his close group of scientist surrendered to American Army on May 2, 1945. Both Americans and the Russians started reverse engineering the rockets and soon produced copies of V2. Russian military saw the rockets as their next super weapon against the cold war with US. A rocket capable of taking nuclear payloads from Russia to US, will completely change the equations in the favor of Russians. 
Russians started assembling a team for their mission led by Sergei Korolev which started working on this rocket. Although,  the rocket he was developing was for military use, he had plans to use it for exploration of space. The Russian teams worked hard to develop an ICBM on the line of Stalin. In contrast to this, in America Von Braun and his group of scientists were involved in teaching the American scientists on the launch and operation of some basic rockets based on V2. The Russian team under Korolev got their first success when they created the world’s first ICBM – the R7 Semyorka rocket. This rocket was capable to taking a 3000 kg nuclear warhead to the range of up to 8000 km.  While the Russians were busy developing the R7; the Americans were planning to launch few satellites in space for scientific purposes through their under development Vanguard rockets, being developed by US Navy. The Eisenhower government did not wanted to create a warmonger with this and thus chose the Vanguard rockets that were for research purposes rather than the Jupiter class of rockets being developed by von Braun and his group for military purposes. If Eisenhower had selected latter, US had been the first country to launch satellite in space. Korolev took advantage of the rivalries between US and USSR to convince the Soviet Academy of Science to create a commission whose sole purpose was to beat US to Earth Orbit, by launching a Soviet Satellite first. On October 4, 1957 Korolev launched Sputnik 1 as the first satellite in space by humans on its R7 rocket. This event shocked the world and caused Sputnik crisis in America. The Eisenhower government now being criticized by media and people, put more emphasis on Vanguard program and launched a slew of measure like National Defense Education Act, which poured billions of dollars to improve American technological advantage and bring back the hurt pride of US back to its glory days. 
The US was still recuperating from this event, when the Soviets gave another serious blow to America by launching another satellite Sputnik 2 in space on November 3, 1957. But, this time, there was a living being on the satellite, a female dog named Laika. This was the first time in human history that a living being was launched into outer space. While the launch of Sputnik 2, brought fears in the mind of Americans of Soviets superiority in science and technology, the Russians were basking in glory. The media and the scientific community called this flight as the precursor to the first manned spaceflight. The Eisenhower government, now under pressure from rising clamour, changed its policy and instructed the Army to prepare for a satellite launch using Jupiter rockets. Meanwhile the launch date of first Vanguard rocket came near. On 6th December, the first Vanguard rocket was to be launched to put America’s first satellite in orbit. The event was a much publicized event, with lot of the event being broadcasted on television. But contrary to hopes of America , the rocket failed to launch and exploded on Launchpad. It was another serious blow to the reputation of America and to the Western World. While the Soviets were breaking one after another frontier of space, the Americans were not even able to launch their rockets. On January 31, 1958 the Army’s satellite launch was scheduled using the Juno rocket which was derived from the Jupiter class of rockets. The launch became successfully and US launched its first satellite Explorer 1 into the orbit. It was this Explorer 1 that discovered the Van Allen radiation belts. 
This launch proved to be a confidence booster, and the US Space Program started catching speed. To add to this, the Eisenhower administration created a civil space agency NASA on July 29, 1958  when he signed the National Aeronautics and Space Act. While the Americans were gaining in space, the Russians were still tangled in bureaucratic struggles. Even after lobbying for months, Korolev was not able to get sufficient support and funding from the government. Although, the Kremlin was happy with the glory that the first satellite launches brought; the program was still being dominated by the military. But the one lead taken by Korolev was in the rockets; the Russian R7 was the most advanced and heavy launch rocket of its day. The rocket was also much more reliable than American counterparts. Taking advantage of this fact, Korolev launched missions to moon – the Luna series of launches that became the first spacecraft’s to reach moon and take pictures of far side of moon. This was another shock to Americans who were now sure of the Russian  supremacy in space. Eisenhower believed that America needed to increase its technological sophistication as US scientists were falling behind the Russian Scientists. On September 2nd 1958, he signed a bill to increase the funding for education and research at all levels with a bill – National Defense Education Act. 
Meanwhile the Russians were trying a different sort of experiment, to launch living beings to space and bring them back. They launched a series of crafts to bring back dogs from space. But, it failed. This brought much criticism to Russian government and they warned Korolev that if any other such incident occurs, the program will be scrapped. But, Korolev, made impossible into possible with his sheer ingenuity. On August 19 1960, Sputnik 5 was launched which took dogs, mice and plants to orbit and brought them back successfully. It was now clear which way the Russian program was going. It came true when on April 12 1961, news came from East that Russians have launched Vostok 1. The Russians had launched the first human spaceflight. The Vostok – K rocket carried Yuri Gagarin to space in the Vostok spacecraft, where he orbited earth once and returned back safely. The flight took 108 minutes from launch to landing and is the shortest manned spaceflight till date. 
The reactions were mixed feelings. While officially US congratulated Russia over the first human spaceflight, internally there were concerns over the future implications of this event. This led to greater pressure on Kennedy government to prove US supremacy in space and is considered an important factor for Kennedy’s declaration of Space Race. Jawaharlal Nehru, the then prime minister of India congratulated Soviets for “ a great victory of man over the forces of nature”. This part of the race was over, and the other was beginning to start. This race was won by Russians, but the Americans were determined to win the next and show their industrial and scientific prowess. Only time knew, what was coming next; but the whole world was waiting eagerly on its heels to see that.

The Rise of Turkey from the Ashes of Ottoman Empire

Turkey or Ottoman Empire as it was known as then, was an ancient empire settled by Ottoman Turks in the end of 13th century. It was a huge transcontinental empire ranging from Caspian Sea in the east to the boundaries of Mediterranean sea in the west. Out of all the invaders who tried to defeat the Roman empire, no one was able to win over the capital of Constantinople; except the fierce Turk warriors, who put the final nail in the coffin of the weak Roman Empire. Whole of the Europe trembled before the disciplined army of the Turks. The empire was at its height in 16th and 17th Century under Suleiman the Magnificent. The location of this empire between Europe and Asia gave Turks the power to control the trade between both.

Like everything, a nation also has a life cycle. First there is the birth of a nation. People are energetic and motivated as everyone is in the beginning of an event. People work hard, nation is administrated properly and as a result, the nations moves to a high growth trajectory. But as the nation grows, it also starts to become rich. Similar to a projectile launched into air, it reaches to a peak; after which due to this growth and money, arrogance appears. And after this the decline begins. The Ottoman empire started declining from the end of 17th century. There were a lot of internal and external factors responsible for this. First of all the Turks were not business minded; they were from a military background and did not encouraged much growth in trade. As the world became further industrialized, ocean routes opened and the popularity of land routes declined significantly. This caused a major drop in Ottoman Empire's economy. While in contrast to this, the new surge in oceanic trade with Asia filled the coffers of European nations with gold. This new rise of Europe lead to inflation in the Ottoman Empire, which in combination of other factors led to serious decline in economy. 

Another factor for decline was the incompetency of the sultans; the sultans after Suleiman were not motivated or energetic towards the growth of the empire. Rather than being an able administrator, they were being seen as the military head of the nation, whose main role was to lead the armies into the war. As a result, Turks were stopped at the gates of Vienna and the few conquests were made after 1565. From ages, Turks had used the war to gain new revenues. This economic decline made their fighting abilities stagnant; while the European armies were growing under the economic boom. This further reduced their political and economic clout.

As the Ottoman Empire began to rot internally, many parts of it started breaking. Greece declared its independence in 1829. In 1875, the Balkan states also declared their independence.It was imminent now that the empire would break apart. All the countries of Europe were witnessing these events carefully. Every country wanted the result in such a way that they are benefited the most. Turkey was called 'Sick Man of Europe' and there was a hoard between England, Russia, Germany and France to get the biggest pieces of it. The burden of wars like Crimean War and the Russo - Turkish War caused irreversible damage to the economy. After a series of wars, the Ottoman empire had been driven out of nearly all of Europe and North Africa and its territory remained as the present day Turkey, Jordan, Syria, Lebanon and few parts of Iraq.

When the World War I started, Ottoman empire fought with the Central Powers of Austria-Hungary and Germany. The main reasons to join war were bitter rivalry with Russians, German pressure, early German gains in the war and to save the disintegration of Empire. After four years of war, the Central Powers lost to the Allies and it was imminent that Ottoman Empire would be divided among Britain and France. The British Prime Minister had promised Greece, that if they join with Allies in the World War, they will be given territories in Ottoman Empire after the war. After the war was over, Greece demanded those territories and under the supervision of England launched a massive attack on Ottoman Empire. France took the areas of Syria and Lebanon, while England took Mesopotamia and Palestine. The Arab lands were also partitioned to create a separate state. Moreover, the Allies were pushing for Treaty of Sevres which was planning severe punishments for Ottoman Empire and would have partitioned it in small pieces.

The Britishers formed a puppet government in Ottoman Empire with a new Sultan at the top following British orders. The people of empire were not happy with this and considered him as a traitor. The cruelties done by Greeks further raised the anger in people. When the news came of the Treaty of Sevres, which would partition the Ottoman Empire into various countries and regions controlled by Allies, people's anger turned to frenzy. Mustafa Kemal Pasha was an army officer who was sent to inner regions to control people and reorganize the remaining troops. But, Mustafa took advantage of the situation and started forming an army to fight the Allies. He also formed an association to gain complete independence of the nation. In the next Parliament elections, the candidates of this party got majority. The Britishers sensing danger to their plans dissolved this parliament. Later GNA(Grand National Assembly) was formed with Kemal Pasha as the speaker.

Kemal disapproved the  Treaty of Sevres and persuaded the parliament to gather an army and fight with the invaders to get complete independence. The GNA Army fight with the Caliphate army and had the main task to fight with the Greek and Armenian forces. After lot of bloody battles, the GNA Army defeated the Greeks and Armenians in many key battles. Allies led by Britishers sensing the success of this expedition, put forwarded an updated version of the Treaty of Sevres with few milder terms. But Pasha, refused it immediately on the grounds that they wanted complete independence; they wanted to form a separate republic of Turkey. GNA refused any proposal that will sacrifice the sovereignty of Turkey, such as the control of Turkey's finances, straits and other international affairs. On 24 July 1923, the Treaty of Lausanne was signed between Allies and GNA; Allies recognized the GNA as the government of Turkey. On October 29 The Republic of Turkey was incorporated.

After the Republic of Turkey was formed; Kemal Pasha became the first President of the new republic. From the beginning Pasha was oriented to form this new republic on the lines of modern states like France, Switzerland, Sweden etc. Pasha formed a treaty with Greece for transfer of Turks living in Greece and same happened for Turkey. This made the nation more homogeneous. With clever usage of events and time, Pasha started to rule like a dictator and abolished Caliphate system. Pasha wanted  the nation to run on  modern values, science and arts rather than on religion. Pasha passed a number of reforms in this direction to take the country away from the religion. The people's dress was changed to western outfits. The 'fez' was also banned and hats like Fedora were encouraged. Pasha brought reforms in the educational sector and persuaded people to educate their girls. The law was changed. The language was changed. The language usage was shifted to Turkish rather than Arabic. Women were given much more independence.

After, these changes Turkey never looked back. An age of prosperity began; even though there was not much changes in the economic life of people. Turkey rose from the ashes of the destroyed Phoenix( Ottoman Empire) and is modernizing rapidly. The ideas of people changed and they started thinking in areas never dreamt before. Pasha's reforms brought Turkey much closer to the western world; even though the economy was growing moderately.  So, it can be said that The Turkey of today, a strong regional power was modernized from the beginnings and the name of Mustafa Kemal Pasha will always remain written in golden words in the history of Turkey.

Inside The Living Body

Yesterday, I watched "Inside the Living Body" a documentary on human body from birth to death. I first heard about it from my cousin brother who had listed it in his Watched Movies List. I was amazed that he had given it 5 stars; as he won’t give 5 stars to even really good movies. According to his rating system, 5 stars are for out of this world eye openers which come one in a blue moon. So, that day only I decided to watch it. I copied it from my brother and stored in my movies folder. But due to one reason or another, I was not getting the time to watch it. Now, around 3 years later I downloaded it from internet and finally watched it. The documentary is of 1 hour 30 minutes and explains the human body during different phases of life starting from birth, to being a toddler to puberty, adulthood and aged. The film shows live footage from the new imaging techniques which allow us to see the body from the inside. We are able to see how food is being transferred from mouth to digestive system and how it is digested. The movie shows many processes of the body in a simple way.

After watching the movie, I realised that how delicate is our body and the whole process of life is based on the intricate balances of chemicals. I wonder how the body is able to do all of these functions. It is nature at its best. Sometimes, I think how can there be so much detail, creativity in the body. It feels like the work of god, because creating such a complex thing and still keeping it simple is still centuries away from the reach of humans. It seems like everything in the body is created after giving a serious thought. Another surprising fact is that the despite being delicate in one sense, the body is so strong. The heart and other vital organs work non-stop for 80-90 years. This is nature at its best.

Another thought which springs to my mind is the undeniable fact of death. The movie explains that as per a theory, the body starts to age from the moment we are born, but in the beginning we have excellent repair mechanism which repairs damaged cells and new cells replace the old ones continuously. But with the age, our repair mechanism weakens and the damaged areas are not healed as fast as they should be. Another theory of aging is that while oxygen is required for us to survive, it also leads to our destruction. Oxygen produces antioxidants which damage our cells. So, the only thing which keeps us alive, also corrodes us from inside. If I have to conclude my feelings, I will say that it is je ne sais qua, its indescribable as I don’t know the words or the way to describe what I am feeling for the ingenuity of nature and our creator.

The Future of Space Exploration

Curiosity has always been the basic trait of humans. We humans have always loved to explore and have tried to answer the greatest mysteries of universe. These mysteries have fascinated millions of minds around the planet. But out of all these, space exploration is on my top priority. I believe that space exploration is not just a fancy program for nurturing human curiosity and inspiring future generations; but is a need for us. Space exploration and the permanent settlement of humans in other locations in universe will diversify the risk and lower the chances of extinction in case of a calamity. Moreover, the rate at which the resources are being consumed and the environment is being polluted, in order to survive we need to mine other planetary bodies.

In spite the importance of space exploration for us, the current efforts being put in it are very less. After a spike in the last half of the century, the innovation in space seems to be at a decline. The simplest example of this is that despite sending multiple crews to moon in the last century, USA the world's only superpower is now struggling to even send their astronauts to LEO. United States is now relying on the Russian Soyuz to send and bring back their crews from ISS. Currently only a few nations are having active space programs - USA, Russia, EU(few nations only), Japan, China and India. Out of these only Russia, China and US have the capability to send astronauts in space.

The future of space exploration also seems not so bright. After the cancellation of Constellation program, Obama launched a new space policy that is without a single goal and intends to develop a heavy lift launch rocket - SLS (Space Launch System) which will be then used to go to asteroids and Mars around 2035. The Russian Space Agency RosCosmos is developing a next generation rocket known as Angara which will be the mainstay of Russia for next decade. Other than this, they are only launching few probes on Moon and a probe on Mars. Indian Space Research Organisation is also sending a small probe 'Mangalyaan' to Mars Orbit this year. But all these efforts are small and don't achieve any ambitious goals that re required in this area. Many other space agencies have future plans, but none is having a plan that we can hope to revolutionize the future. CNSA(China National Space Administration) is a taking few steps in the correct direction. CNSA has launched multiple manned missions in space and has started an ambitious project called Project 921 to build a space station in earth orbit

Other than these public efforts to explore space, the last few years have seen private sector entering space sector. Most of these companies are located in US and are a result of NASA's programs like COTS, CRS and CCDev which fund private companies to develop capabilities in space. The main aim of NASA with this is to build a competition in private sector for LEO launches. This will lower the cost of launches,  build new capabilities in space, bring forth new innovative ideas and let NASA focus beyond LEO. I believe this is a master stroke by NASA. These programs have brought forward companies like SpaceX and Orbital Sciences which have developed some really innovative and powerful rockets. SpaceX has demonstrated its Falcon 9 rocket capabilities by flying multiple missions to space with its spacecraft Dragon berthing with ISS. On September 18, Orbital Sciences flew their Antares rocket which launched its Cygnus spacecraft in space which then docked with International Space Station. SpaceX has also won contracts for future satellite launches due to its low cost launches.

The private efforts are still in the nascent stages, but hold the potential to shine in the future. But to carry on this momentum to the future, government needs to think ambitiously and plan a space policy which will revolutionize the industry like the Apollo missions. I am not an aerospace engineer, but a enthusiast who 
wants a great revolution in this field. So, I have thought a lot about these and finally I have planned a policy which I will start if I have the power to do so for NASA.

  • First of all funding, like all other things exploring space needs money. The current budget of NASA is very less than what is required for such feats as we expect them to do. First of all the budget of NASA should be increased from the current 16 Billion dollars to 19 Billion dollars till 2020. Moreover, a frugal approach should be implemented to reduce the costs. Space agencies like ISRO and CNSA are a perfect example of what can be done even with low costs. We cannot reduce the costs at the level of these agencies, but we should learn where we can. Moreover, rather than becoming totally dependent of federal budget, NASA should focus to find some new avenues for money like funding drives and licensing some older technology etc.
  • Second, the decision of Obama to continue the usage of International Space Station is a good move. US has spent billions of dollars to build the space station. Now, when the time has come to reap the benefits of the investment it should not be discontinued. In my opinion, the ISS should be continued till 2025 at least. These space stations are a first step for human settlement in the space in future. The International Space Station should be used to its fullest extent and a variety of new research experiments should be started. After this space station is retired, NASA should collaborate with private companies like Bigelow Aerospace to create private space stations.
  • Meanwhile, learning from the success of ISS, NASA should give private contracts to start building a small space station in lunar orbit around 2020 which should be completed by 2027. This will create a new era and will allow the continuous monitoring of moon. Once such a space station is created, it will be very easy to conduct missions on Moon. The space station will allow crewed visits and is a pre-requisite for temporary settlement in Space. Private companies like SpaceX are already planning to build Falcon 9 Heavy rocket which can take huge payloads to the space. Morever, by this time the SLS will also be in its initial stages.
  • The other logical step after/before building the space station in lunar orbit will be to create a propellant depot in the Lagrange point L1 around 2028. This will increase the reach of humans into space exponentially, the spacecrafts then can carry huge payloads into orbit and less fuel, which they can then refill at the depot. This depot should be an international effort and should take place as a collaboration between all the major space agencies of the world. The  embers can use this facility at a much cheaper rate than the non-member states.
  • After this, the crewed landing on the moon can be much more frequent and much bigger experiments like moon mining can be performed.The lure of mining in space and federal incentives for that can pull the private companies from Earth easily. This can be followed up by a temporary moon colony by 2050.
The above points represent my view on the space policy which should be followed. The greater participation of private organisations will hep in further reduction in launch costs and these structures will further act as boosters for exploratory missions in deep space. Maybe, by 2100, we will have a permanent settlement on Mars and crewed mission on Europa and Titan take place. 

Lagrange Points
What I really want is to experience the moment, when one of my friend says that I cannot come for party next weekend, my uncle living on Moon are coming to attend the marriage of my relative's daughter with a guy working on Mars.  WOW !!

World War I : A Brief Overview

World War I or The Great War is one of the most important events in the world history. It changed the world forever in every aspect. Even though the war was fought in the European continent, the repercussions were felt throughout the globe. The Great war was fought between 1914 to 1918 between the Central Powers and the Allied Forces. The Central Powers were led by Germany and comprised of Austria-Hungary, Ottoman Empire and Bulgaria, while Allied Forces comprised of British Empire, France, Russia, United States and plethora of other small European nations. Even though the battle already looks skewed in the favor of Allies, Austria-Hungary only looked strong on paper and was weak in reality; While Ottoman Empire was already the Sick Man of Europe. So, the war was actually between the Allies and Germany with little inputs from other Central Powers.
The war was already inevitable in the beginning of century due to the resurgence of capitalism. Industrial Revolution came early in the western Europe and countries like England, France and Holland benefited heavily with that. These countries grew their industrial production rapidly and made colonies all over the globe as markets to sell these manufactured goods. Leading all these nations was the British Empire having Canada, Australia, Egypt and lot of other countries with India as its crown jewel.

The newly industrialized nations felt cheated that there were no colonies left for them to exploit. The only colonies left were not as valuable as ruled by British or French Empires. In contrast to them, Germany only had three colonies in Africa. Even despite this disadvantages, Germany grew rapidly and became an industrialized nation. German army became one of the strongest armies in the world. On some social indicators, it even beat England. In England, the resentment against Germany started growing. So, in the first decade of twentieth century, almost all the countries of Europe started war preparations internally; nations were stockpiling ammunition as the war was inevitable in near future.

The spark to this bubble of gas was provided on 28 June 1914, when the Archduke Franz Ferdinand, the heir to the throne of Austria-Hungary was assassinated while his tour of Bosnia. The assassination was done by a Serbian student, and thus Austria blamed Serbia; Serbian apologies were unaccepted and an ultimatum was given to Serbia to accept 10 unacceptable demands drafted in a way to provoke war. Still Serbia accepted 9 out of 10 demands. But this was not enough, and one month later on 28 July, Austria-Hungary declared war on Serbia. The Russian Czars didn't wanted to lose the influence in Balkan States and ordered  a partial mobilization of troops one day later. Germany saw this mobilization of troops as a threat to herself and launched attacks on France and Russia on 30th July. Between the two hostile nations of France and Germany was a neutral land of Belgium. Germany asked Belgium to allow German troops to pass through so that they can attack France. Belgium refused; Germany attacked Belgium on 3rd August. Britain took advantage of this and used this violation of neutrality pact by Germany as a reason to launch war against it. So, the World War stared with The Triple Entente of UK, France and Russia against the Germany and Austria-Hungary. Italy kept watching and joined the Allied Forces next year. Both the groups tried to take other nations into their sides by offering them promised territories once the war is over.

Allies(Green) Vs Central Powers (Orange)
Germany gained quickly on the French troops and took control of important industrial regions. But after initial success, French were able to stop them 70 km from Paris. This turned out to be a major turn in the war as after this the trenches were formed and trench warfare kept on going on for 2 years. It led to stalemate with no side gaining any territory. The Germans used chemical weapons like Chlorine gas and mustard gas, but still the stalemate remain so. The war also led to introduction to technological improvements in warfare with tanks and aircraft's introduced in war front.

Meanwhile, another battle was being fought in the seas. The British Navy was the biggest and strongest navy in the world and it started a blockade of Germany in order to starve her and force her to surrender. While a counter offensive was launched by Germany to blockade Britain who was dependent heavily on imports for food supplies. German submarines hunted in the international waters to block ships entering into British waters. In 1917, Germany was tired and the British blockades were making a serious dent on Germany. So, they changed their strategy to attack even neutral ships coming to Britain with supplies. On 6 April, 1917 US declared war on Germany after Germany sank 7 US merchant ships and tried to cajole Mexico in joining the war against US. But these were not the only reason why US came into war. The another reason was money.

Every war needs money, lots and lots of money. In the beginning, France financed the Allied war, but by 1915, France was done. So, Britain stepped in and started financing the whole war. Britain financed for one year. But by the year of 1916, Britain also got broke. Then, both Britain and France went to USA for help and asked them to finance the war. USA agreed and started lending heavy amounts to Allies for their war. US had invested so much money in the war that if Allies had lost the war, US economy had gone into a recession. So, to save its own skin, US jumped into the war. The entry of US changed the dynamics of war totally. 

But there was one more major event left to happen. This was to happen on Eastern Front. The Russian armies fought with the Austrian - Hungary armies and were pushing them back easily. Then, Germany sent her troops and they were able to turn the tides. The superior German army - better led, better trained and better supplied were terrifyingly effective against the ill-equipped Russian forces. Moreover, the burden of war was too much for the common man of Russia and this increased the anger of people against the Tsars. Various strikes and demonstrations started against the Russian king. The biggest of this revolt started November 7 1917 as the October Revolution by Lenin. This led to the coming of Bolsheviks to the power. Bolsheviks led by Lenin had a socialist agenda and they wanted peace at any cost. Thus, the treaty of Brest-Litovsk was signed between two, with Russia paying a heavy cost.

But this brought an advantage to Germany, that now they can shift their entire focus on the Western Front. At this time, Germany was strong enough to fight with the France and Britain and win. Thinking on the same terms, Germany launched the Spring Offensive in 1918 and thought to win the war before US forces make any major contribution. But the Russian Revolution was impacting German people also. Now, people of Germany were also tired after fighting such a long battle, they wanted peace.Anti-war protests started in Germany and the soldiers shifted from Eastern front told other soldiers of the Russian Revolution. Thus, Germany started to weaken. Moreover, the Spring Offensive did not provided her with any major gains as due to improper supply lines and lack of tanks and artillery, Germany was not able to consolidate any considerable gains.

In response to the German Spring Offensive, Allies launched a counter - offensive named as Hundred Days Offensive. It began on August 8 1918 with the Battle of Amiens. This became a successful strategy and the Allies were able to gain considerable areas in the war. The weak Germany with a blockade leading to starvation at home, talked for armistice, but the Allies refused and demanded abdication of Kaiser. Thus, the Imperial Germany was no more and a new Republic Germany was formed.  But, the British did not removed the blockade till 8 months of peace treaty signed. The blockade led to starvation in Germany. The Blockade was not removed till 12 July 1919 when the the Treaty of Versailles was signed between Allies and the Central Powers. These times became one of the most devastating periods for the German people and it was claimed that 100,000 Germans died due to the continuation of blockade. German Chancellor Hollweg sayed that "and our children, and children's children, will bear traces of the blockade that England enforced against us, a refinement of cruelty nothing  less than diabolic."

Thus, the Great war ended in 1918, and the world was changed entirely. New nations were formed. Many old were no more. The industry, economy and politics of the world was never the same. The treaties done by Allies were very harsh and sowed the seeds for the World war II. Whatever happens, the World War I will be always remembered for the impact it had on earth.

The Mobile Timeline

Till now, I have had a number of mobiles, this post is a collection to just remember the best gadget known in 21st century. 
  • Motorola T190: This was my first mobile phone which I started using around 2003. It was of a white color and the body was sleek and sturdy. There was a small antenna protruding from the top right corner, but overall the design was good. The best feature of the phone was the small size of the mobile. Today, I may be using any smartphone, but the feeling I got after using this phone was amazing. It did not had any features of today's smartphones, but truly your first mobile phone has a je ne sais qua which binds you with it. 
Motorola T190
  • Nokia 2300: Nokia's 2300 was my second mobile. I got it from my sister in 2006. It was then the new kid in town and was a head turner with its sleek design and eccentric keypad. It was of greyish color. The display was much better than the Motorola and it also had FM Radio. I still love this phone. I still remember the nights I wasted playing Snake II, Opposite and Space Impact + on it. I made huge high scores on it. It also had polyphonic ringtones and a composer where one can build one's own ringtones. I remember how I used to play with composer and trying to build a new tone.

  • LG KS 360: The next phone in line was the LG's KS 360. It was a blue color slider phone with QWERTY keypad and touch screen only on keypad. This was a little weird feature as the touchscreen only worked while dialing numbers. I used this phone a lot during my college. It also had a small camera, but the quality was moderate only. I bought this phone from my cousin around 2009 for 4000 bucks, but totally loved it.

  • Nokia E63: This phone I got in 2011 from my brother. It was a red color candy bar shaped phone with a qwerty keyboard and other advanced features like Wi-Fi. I used this phone during my last year of college and the first year of my job. E63 also supported Symbian app store and I watched countless videos on YouTube on this phone.Other apps which I used a lot on this phone were Whatsapp, Word and few Java games. As of now, the phone is horrible situation. The back cover is fully cracked and is going to break. The keyboard has lot its luster and the battery life is pathetic. But, I cant remember the moments I had with this phone.
Nokia E63

  • Samsung Galaxy Note: This was the first mobile phone which I bought with my own money for myself in May 2012. I was so excited to buy it. Never before I had the chance to buy something for myself. It was a top end Android phone with all the best features of the time. It was like a dream come true. I spent 1.5 times my monthly income on this phone. Now, I believe how naive I was. It got stolen at a bus stop one month later; even before I had the chance to pay the first EMI.
Samsung Galaxy Note
  • Nokia Lumia 720: The latest smartphone still with me is the Lumia 720 powered with Windows Phone 8. It is a gorgeous phone with great look and smart features. I am loving it even more than the Note. There are very few apps in comparison with Android or iOS, but it feels good to use. My phone is yellow colored and to truly say, I am still in fear that it is not stolen again. Don't know when I will overcome this feeling.

This is the list of phones till September 2013. Lets see who's next...
