...celebrity also gave her the opportunity to speak out on concerns she felt strongly about. As early as 1945, Carson and her close colleague Clarence Cottam had become alarmed by government abuse of new chemical pesticides such as DDT, in particular the "predator" and "pest" control programs, which were broadcasting poisons with little regard for the welfare of other creatures. That same year, she offered an article to Reader's Digest on insecticide experiments going on at Patuxent, Md., not far from her home in Silver Spring, to determine the effects of DDT on all life in affected areas. Apparently...
...Carson could count on the support of leading scientists and conservation organizations, and was well positioned to command a hearing. Even so, the Digest and other magazines had little interest in this gloomy subject. Then, in 1957, there was a startling wildlife mortality in the wake of a mosquito-control campaign near Duxbury, Mass., followed by a pointless spraying of a DDT/fuel-oil mix over eastern Long Island for eradication of the gypsy moth. Next, an all-out war in the Southern states against the fire ant did such widespread harm to other creatures that its beneficiaries cried for mercy...
...Bell Labs, Shockley recognized early on that the solution to one of the technological nightmares of the day--the cost and unreliability of the vacuum tubes used as valves to control the flow of electrons in radios and telephone-relay systems--lay in solid-state physics. Vacuum tubes were hot, bulky, fragile and short-lived. Crystals, particularly crystals that can conduct a bit of electricity, could do the job faster, more reliably and with 1 million times less power--if only someone could get them to function as electronic valves. Shockley and his team figured out how to accomplish this...

...organization gave him $30,000 and told him to develop a contraceptive that was "harmless, entirely reliable, and aesthetically satisfactory to husband and wife." Within 10 years, however, Pincus and his colleagues delivered, inventing the drug that sparked the sexual revolution. Introduced in the U.S. in 1960, the birth control pill, known simply as the Pill, was an ovulation-suppressing mix of estrogen and progestin that was 99% effective...
