We decided to go for a bath in Ganga. We chalked out a programme to go on a boat from Baluaghat to Sangam. The idea was liked by all. So we started on foot to Baluaghat. We were 16 in number. We chose a small boat beautifully decorated. The remuneration was settled and we sat in the boat. There v/ere two boat-men. They asked us to sit properly on both the sides of the boat. The boat sailed. It moved gently. We saw the buildings on the banks. It was pleasant sight to watch. We were going down the current. So the boatmen had not to work hard.

One  of the  most  beautiful achievements of man is a garden. Man has loved gardens and gardening from the earliest times. Gardening is a delightful and interesting hobby. 'Garden refreshes the spirit of a man, without which buildings and palaces are but gross handy works,' wrote Bacon. A beautiful garden is in itself a constant source of pleasure. It forms a quiet retreat where one can rest far from the madding crowd. Soothed by the singing of birds, a weary man enjoys soothing coolness. Smooth green lawns of grass with beds of gay flowers fill the air with sweet smell. No wonder, man has dreamt of garden, the Paradise on earth. It is the expression of his first state of innocence,                          Gardening promotes physical as well as mental health. Looking after a garden all the year round with more...

Russell Ohl (1898-1987) was a precocious talent who by the age of sixteen had already entered Pennsylvania State University After a period in the Army Signal Corps and a brief career as a teacher, OhI finally took a research position in U.S. industry. Early radios were only able to receive low- frequency transmissions. At Bell Labs in Holmdel, New Jersey, Ohl worked to create an improved radio receiver for high frequencies. Here he experimented with semiconductor materials that he thought would outperform the electron tubes used in existing receivers. An expert in the behavior of crystals, Ohl investigated different materials for semiconductors, such as germanium and silicon. The crystals were heated, and when cool would be sliced for use. In 1939 Ohl was working with a silicon sample that he noticed had a crack down the middle. When he tested the electrical resistance of the sample he noted that when more...

"An antibiotic for all seasons, it's used for a dozen reasons... there is no proxy, for our antibiotic doxy." James McCallum, from the poem "Doxycycline" The world existed for a long time without antibiotics, but as soon as they were discovered, the race was on to find more. Penicillin and streptomycin had both been isolated from some form of fungus, and the search continued for products that came from naturally occurring bacteria. Research groups looked everywhere but one of the more promising avenues of investigation began to emerge from groups studying certain fungi that lived in soil—organisms known as actinomycetes. Lederle Laboratories found the now forgotten antibiotic aureomycin in dirt samples. Pfizer soon followed suit with the equally obscure antibiotic terramycin. Both aureomycin and terramycin functioned as broad-spectrum antibiotics, covering a range of both gram- positive and gram-negative bacteria. This sparked a great deal of interest in figuring out how more...

"The Space Shuttle is the most effective device known to man for destroying dollar bills." Dana Rohrabacher, U.S. Congressman Booster rockets—such as the Saturn V that launched the Apollo astronauts toward the Moon—are extremely wasteful. They can fly only once, parts are thrown away after use, and 97 percent of the mass is Consumed in the first few minutes. Clearly, what was really needed for advanced and economic space exploitation was a spacecraft that could take off and return, to be reused time after time. In 1972 NASA-.in the United States decided to build the Space Shuttle. Rockets were to be used to assist the launch. Crew facilities were to be provided for up to eight people, and the huge cargo bay would be used to take satellites and sections of the International Space Station (ISS) into orbit. New instruments would also be taken up to existing spacecraft, and In-orbit more...

In 1952 Gregory Pincus (1903-1967), a biologist working at the Worcester Foundation for Experimental Biology in the United States, demonstrated that a synthetic form of the hormone progesterone, known as norethidrone, inhibited ovulation in rabbits and rats. Norethidrone had been developed a year earlier by Carl DJerassi, a chemist working at the Syntex company in Mexico City. It had initially been created with the aim of producing high concentrations of progesterone to treat menstrual disorders. It had the advantage of being more active than the human hormone, and also of being effective when taken orally. Margaret Sanger, founder of the American Birth Control League, saw the potential of Pincus's work. She enlisted the help of heiress Katharine McCormick, who agreed to fund research to develop a contraceptive pill. Pincus developed a pill with the aid of gynecologist John Rock (1890-1984), a devout Catholic aiming to improve conception among infertile couples. more...
