Japan, Bullet Train and India

Many Indians have grown up with the wonder of Bullet Train, a synonym for technology, speed, and comfort. The Japanese are the pioneers of high-speed trains (French close competitors with TGV in Europe) and due credit to Mr. Hideo Shima, the father of the Shinkansen train aka the bullet train. It’s not a pleasant surprise that the Japanese government will be facilitating the development of high-speed rail in India. The public-private partnership model sponsored by Japan offers an extremely generous rate of 0.1% with repayment of 50 years for the yen denominated loan. A huge game changer for India, trains would be operating at speeds between 300 to 350 km per hour. It’s going to save travelling time, increase productivity and over medium term bring down costs of traveling within India especially airfare. India will buy 18 Shinkansen train sets with the first high-speed rail working by 2022 between Mumbai and Ahmedabad. Apart from extremely benevolent funding agreement,  there is also  provision of transfer of technology to develop production locally. An article published in Economic Times, states that the economy class will only cost INR 3000 (USD 40) for travel time between Mumbai and Ahmedabad (508 km). This is one of the best policy initiatives taken by the government and must be given the utmost importance for support for effective implementation. Further high-speed railway network should be implemented nationally along key routes with increased alacrity.  Continue reading “Japan, Bullet Train and India”

Why India needs a lot of fighter jets? RAFALE & GRIPEN

Dassault has finally cleared the controversy over Rafale planes, and its time we move ahead with more orders for fighter planes. Indian Air-force desperately needs fighter planes to replenish its existing defunct MIG 21 and MIG 27 squadrons. I am writing this article as an exception. A country must have a redoubtable defense to protect against any threats. Generally a critic of defense spending, here I am emphasizing purchase of fighter jets. Compared to peers, India lags behind in defense know how in spite of many attacks and threats to our motherland. Continue reading “Why India needs a lot of fighter jets? RAFALE & GRIPEN”

Quarks

Going ahead with my article on elementary particles, a fact about matter particles i.e. quarks. Individual quarks cannot be observed while only bounded states of quarks and anti quarks known as mesons are  observed.  Quarks have asymptotic freedom i.e. force between quarks is weak over shorter distances while stronger over longer distances. This is a  small correction to my earlier article wherein it could be implied that individual quarks had been observed.

 

One for Science: Elementary Particles, Mass and Forces of Nature

In pursuit of science, fitness, and happiness, this article is a continuation of the video shared here on fat loss. The chemical equation of human fat C55H104O6 decomposes into Carbon and Oxygen.  Ruben Meerman’s video on the mathematics of weight loss led to the genesis of this article. Dipped with a small dose of quantum mechanics, this article shares a very brief overview of the micro world of elementary particles and laws of nature governing our bodies and this Universe.

Carbon, Hydrogen and Oxygen atoms play a fundamental role in burning fat. About 96% of human body is made up of carbon, oxygen, hydrogen, and nitrogen. Hydrogen and Helium are also the elements which build the atomic mass of our universe. Hydrogen and Helium atoms make up 99.8 % of all atoms and 98% of all atomic mass in the Universe. An atom has protons and neutrons in its nucleus with electrons orbiting the nucleus.  Protons and neutrons have the same weight which is much more than the weight of electrons. Mass of electrons is negligible compared to the weight of protons and neutrons. The number of protons decides the elementary characteristics of the elements on the periodic table. The mass differs from the weight. Mass measured by mass of atoms in the body which is equal to the mass of protons and neutrons combined. Mass is constant while weight changes according to the gravitation pull of the planet. The movies Interstellar and The Martian are good examples of how weights can vary in different planets. Continue reading “One for Science: Elementary Particles, Mass and Forces of Nature”

Math of fat and weight loss: Is there an arbitrage ?

Many fitness enthusiasts might not be aware that fat has a mathematical equation.  Have you ever wondered how does weight loss happen ? Welcome to an intersection of science, mathematics and  weight loss. Coming soon mathematics of fat and the art behind weight loss…

I shared this video with a few people before I decided to post here. The equation of human fat is C55H104O6.  The article is intended to be a lot on fundamentals of physics and will try to complete the article by tomorrow. Till then, watch this informative video…

Statistics series will soon begin. Three types of statistical methods are used throughout econometrics : estimation, hypothesis testing and confidence intervals.  Stay tuned…

Rise of Impact Investing in India

Impact investing in India is the largest in South Asia and second in the world according to a report published in May 2016, titled A decade of impact investing in India. Impact investing or impact capital’s mission is to create a positive social impact related to social or environmental cause along with a financial return. Impact capital has a dual goal, blended, between social (first priority)  and financial return. Continue reading “Rise of Impact Investing in India”
