1952

First thermonuclear bomb tested by the United States
On this day in 1952 on an atoll of the Marshall Islands, Edward Teller and other American scientists tested the first thermonuclear bomb, its power resulting from an uncontrolled, self-sustaining nuclear chain reaction.

Thermonuclear bomb, also called hydrogen bomb, or H-bomb, weapon whose enormous explosive power results from an uncontrolled self-sustaining chain reaction in which isotopes of hydrogen combine under extremely high temperatures to form helium in a process known as nuclear fusion. The high temperatures that are required for the reaction are produced by the detonation of an atomic bomb.

What is the difference between nuclear fission and fusion?
[size=14]See all videos for this article[/size]
A thermonuclear bomb differs fundamentally from an atomic bomb in that it utilizes the energy released when two light atomic nuclei combine, or fuse, to form a heavier nucleus. An atomic bomb, by contrast, uses the energy released when a heavy atomic nucleus splits, or fissions, into two lighter nuclei. Under ordinary circumstances atomic nuclei carry positive electrical charges that act to strongly repel other nuclei and prevent them from getting close to one another. Only under temperatures of millions of degrees can the positively charged nuclei gain sufficient kinetic energy, or speed, to overcome their mutual electric repulsion and approach close enough to each other to combine under the attraction of the short-range nuclear force. The very light nuclei of hydrogen atoms are ideal candidates for this fusion process because they carry weak positive charges and thus have less resistance to overcome.

Gary Player
South African golfer

Britannica On This Day November 1 2023 Gary-Player

.Gary Player, in full Gary Jim Player, byname the Black Knight, (born November 1, 1935, Johannesburg, South Africa), South African who was one of the world’s best professional golfers in the post-World War II era. He was the third man (after Gene Sarazen and Ben Hogan, both of the United States) to win the four major tournaments composing the modern golf Grand Slam.

In 1955 Player entered competition on the Professional Golfers’ Association (PGA) of America circuit of tournaments, and in 1961 he was the leading winner of prize money on the circuit. His international record, unsurpassed by any golfer, was a tribute to his remarkable fitness and love of competition. Player was an integral part of the popularization of golf in the 1960s, as his weekly competitions with fellow golf stars Jack Nicklaus and Arnold Palmer showcased the sport being played at its highest level. His nine career wins at the major tournaments—the Open Championship (British Open; 1959, 1968, 1974), the Masters (1961, 1974, 1978), the PGA Championship (1962, 1972), and the U.S. Open (1965)—are the fourth highest total in golf history (tied with Hogan). He also won the South African Open 13 times, the Australian Open 7 times, and the World Series of Golf 3 times (1965, 1968, 1972).
