THE CYCLONE
THE CYCLONE: _ _ Prologue: I am not fond of weather analysis. Many times I inadvertently watch weather forecast on TV which I find quite boring. Nonetheless, after discussing earthquakes and tsunamis, I felt that I should discuss adverse weather events which also affect our lives. A storm is any disturbed state of atmosphere, and strongly implying severe weather; marked by strong wind, thunder, lightning and heavy precipitation (rain, ice etc). Storms are created when a center of low pressure develops, with a system of high pressure surrounding it. This combination of opposing forces can create winds and result in the formation of storm clouds. Storms generally lead to significant negative impacts to lives and property. The vertical wind shear in thunderstorm can cause airplane crashes. Severe weather is also responsible for plenty of helicopter crashes, and delay launch of space shuttles. There are various types of storms including tropical […]
THE SCIENCE OF RELIGION
THE SCIENCE OF RELIGION Caveat: The purpose of this article is not to discuss any specific religion but to discuss relevance of various world religions in the context of science and therefore specific details about various religious beliefs relating to the existence, nature, and worship of any deity; and the values & practices advocated by any prophet or sacred text will not be discussed. Also, no attempt is made to show superiority or inferiority of any religion with respect to other religions. Instead, an attempt is made to discuss all religions together vis-à-vis science. I offer unconditional apology to anybody hurt or offended by this article. I am willing to post any criticism of this article below this article itself provided the browser logs in my website. _ Prologue: When I wrote an article on my wall in Facebook about “The Coincidence”, my intention was to educate masses about the […]
THE NANO WORLD
THE NANO WORLD Prologue: Can you identify what is this? A group of scientists discovered that placing gold nanoparticles within the leaves of trees causes them to give off a luminous reddish glow. The idea of using trees to replace street lights is an ingenious one – not only would it save on electricity costs and cut carbon dioxide emissions, but it could also greatly reduce light pollution in major cities. The picture speaks louder than the words. Majority people of the world know very little about nanotechnology & nanoparticles but we are ushering in an era of nano-revolution which is going to change our lives for ever. I myself was as ignorant as you on this subject until I decided to welcome the year 2011 with a novelty. Nano (symbol n) is a prefix in the metric system denoting a factor of 10 – 9 or 0.000000001. The […]
GENETICALLY MODIFIED
GENETICALLY MODIFIED (GM): Prologue: A year 2006 study of the global impact of GM crops, published by the UK consultancy PG Economics and funded by Illinois-Missouri Biotechnology Alliance concluded that globally, the technology reduced pesticide spraying by 286,000 tons in 2006, decreasing the environmental impact of herbicides and pesticides by 15%. On the other hand, a year 2009 study published by the Organic Center stated that the use of genetically engineered corn, soybean, and cotton increased the use of herbicides by 383 million pounds, and pesticide use by 318.4 million pounds. Whom to trust? This is the paradox about GM food. There are thousands of studies and research works on GM whose conclusions contradict each other. People are caught in the cross-fire between pro-GM lobby and anti-GM lobby. I do not know the truth but I will try to educate people on the most controversial issue of 21’st century. […]
HUMAN ERROR
HUMAN ERROR Prologue: On 10’th December 1996, the Mumbai high court passed an ex-party order asking me to pay rupees 10,000 every month to estranged wife on the ground that my lawyer was absent in the court-room. I immediately appealed to the divisional bench of Mumbai high court. The divisional bench of two judges heard my appeal and reduced the amount to rupees 7,000 in the open court in front of everybody present and dictated the court typist to type the new order. The court then got busy with many other matters pending before it. However the court typist typed rupees 10,000 in the new order. Later on, my lawyer met the judges in their chamber and pointed out the typographical error. The judges refused to accept human error and said that due to inflation, cost of living is more and therefore rupees 10000 is appropriate. Till today, I […]
