Plutonium: A History of the World's Most Dangerous Element by Jeremy Bernstein

By Jeremy Bernstein

Whilst plutonium was once first synthetic at Berkeley within the spring of 1941, there has been so little of it that it used to be now not obvious to the bare eye. It took a 12 months to amass adequate in order that you can really see it. Now there's loads that we don't understand what to do to do away with it. now we have created a monster. The background of plutonium is as unusual because the point itself. while scientists begun trying to find it, they did so easily within the spirit of inquiry, no longer sure no matter if there have been nonetheless spots to fill at the periodic desk. however the discovery of fission made it transparent that this still-hypothetical aspect will be greater than only a clinical interest - it can be a robust nuclear weapon. because it became out, it truly is stable for nearly not anything else. Plutonium's nuclear power placed it on the center of the area struggle II fingers race - the Russians discovered approximately it via espionage, the Germans via autonomous study, and everyone sought after a few. Now, approximately every person has a few - the U.S. by myself has approximately forty seven metric plenty - however it has nearly no makes use of in addition to warmongering. How did the made from clinical interest develop into this sort of harmful burden? In his new historical past of this complicated and hazardous aspect, famous physicist Jeremy Bernstein describes the stairs that have been taken to remodel plutonium from a laboratory novelty into the nuclear weapon that destroyed Nagasaki. this is often the 1st publication to weave jointly the numerous strands of plutonium's tale, explaining not just the technology however the humans concerned.

Black Hole: How an Idea Abandoned by Newtonians, Hated by Einstein, and Gambled on by Hawking Became Loved

For greater than part a century, physicists and astronomers engaged in heated dispute over the potential for black holes within the universe. The weirdly alien thought of a space-time abyss from which not anything escapes—not even light—seemed to confound all common sense. This engrossing ebook tells the tale of the fierce black gap debates and the contributions of Einstein and Hawking and different best thinkers who thoroughly altered our view of the universe.

Not Even Wrong: The Failure of String Theory and the Search for Unity in Physical Law

At what aspect does conception go away the area of testable speculation and are available to resemble whatever like aesthetic hypothesis, or perhaps theology? The mythical physicist Wolfgang Pauli had a word for such principles: He could describe them as "not even wrong," that means that they have been so incomplete that they can now not also be used to make predictions to check with observations to work out whether or not they have been flawed or now not.

Meitner was given a copy of the medal. She certainly never complained publicly about this and even wrote Hahn a congratulatory note. But while they remained friends and colleagues, she did not collaborate with him again for more than a decade. By the time their collaboration resumed in 1934, the political situation in Germany had changed radically: The Nazis had come to power. This event affected Hahn and Meitner in different ways. In 1908, Meitner had been baptized. She had never had any connection with the Jewish community, and two of her sisters had converted to Catholicism.

The problem she had was that her samples of radium were contaminated with barium. ” This process takes advantage of the fact that, in a suitable solvent, different chemical compounds form crystals at different rates. Compounds have different degrees of solubility. The experimenter tries to concentrate what he or she is looking for in the crystals and remove the liquid. Madame Curie discovered that the radium salt was less soluble than the barium salt, so it became concentrated in the crystals. This was an immensely tedious task, but it worked.

In his autobiography, A Mind Always in Motion,3 Emilio Segrè notes that for the fun of it the young physicists around Fermi decided to give themselves ecclesiastical names. Segrè was known as the Prefect of Libraries because of his interest in physics literature. Orso Corbino, who ran the physics department and was also a state senator, was known as the Heavenly Father. Ettore Majorana, who was a brilliant and very critical theorist, was known as the Grand Inquisitor. ) Fermi was, of course, known as the Pope.
