SELF MEASUREMENT OF BLOOD PRESSURE (SMBP):
SELF MEASUREMENT OF BLOOD PRESSURE (SMBP): ________ The figure above shows correct way to measure blood pressure at home. _______ Prologue: When the heart beats it generates a pressure in the arteries to pump blood around the body. In some people, the pressure generated is too high and this is called hypertension. Way back in 1981, Dr. R. C. Hansoti was head of cardiology department in Nair hospital, Mumbai and he was taking a clinic on hypertension for a group of medical students and I was one of the medical student attending his clinic. He asked a question to everybody: What are the symptoms of hypertension? Some said headache, some said giddiness and some said palpitation. When my turn came, I said hypertension has no symptoms. Dr. Hansoti was satisfied with my answer. He said that there is only one wise doctor among the crowd. I felt elated. Even today, I […]

THE ATOM
___________ THE ATOM: ___________ The figure above is an animation of the nuclear force (or residual strong force) interaction between a proton and a neutron. The small colored double circles are gluons, which can be seen binding the proton and neutron together. These gluons also hold the quark-antiquark combination called the pion (meson) together, and thus help transmit a residual part of the strong force even between colorless hadrons. Quarks each carry a single color charge, while gluons carry both a color and an anticolor charge. The combinations of three quarks e.g. proton/neutron (or three antiquarks e.g. antiproton/antineutron) or of quark-antiquark pairs (mesons) are the only combinations that the strong force seems to allow. ________ Prologue: Since childhood I was curious about breaking down any matter (table/chair) into smaller pieces continually till I reach a point where it cannot be broken down. What is that point? Is matter infinitely divisible? […]
ALCOHOL (beverage based on ethanol)
______ ALCOHOL (beverage based on ethanol): ______ President Obama loves Irish beer and celebrates the St.Patrick’s Day only with it! ________ Prologue: Abraham Lincoln said: “It has long been recognized that the problems with alcohol relate not to the use of a bad thing, but to the abuse of a good thing.” We find alcohol throughout our daily lives. Alcoholic beverages have been consumed by humans since prehistoric times for a variety of hygienic, dietary, medicinal, religious, and recreational reasons. We associate the consumption of alcohol with the most pleasurable aspects of our culture. Parties and sports, picnics and vacations, summer and winter are all influenced by the attraction of alcoholic beverages. World Cup 2014: festival of football or alcohol? Whichever country hoists aloft the World Cup trophy, the real winner will be the alcohol industry according to BMJ report. I had written article on ‘Alcohol’ on February […]
SCIENCE OF LANGUAGE
_ SCIENCE OF LANGUAGE: _ The figure above shows English to Gujarati mappings for consonants: _________ Prologue: Human life in its present form would be impossible and inconceivable without the use of language. To the question: “Who is speaking?” Mallarme, the French poet, answered, “Language is speaking.” The traditional conception of language is that it is, in Aristotle’s phrase, sound with meaning. Everybody uses language, but nobody knows quite how to define it. Language is arguably the defining characteristic of the human species, yet the biological basis of our ability to speak, listen and comprehend remains largely mysterious; about its evolution, we know even less. The origin of language is a widely-discussed topic. Whole doctorates have been based on it, thousands of books have been written on it, and scholars continue to argue about how and why it first emerged. Many animals can communicate effectively with one another but humans […]
