[MINT] NEEWER TT560 Speed Lite DSLR cameras with single hot shoe: I used to wonder how it comes about that the electron is negative. Negative-positive—these are perfectly symmetric in physics. There is no reason whatever to prefer one to the other. Then why is the electron negative? I thought about this for a long time and at last all I could think was “It won the fight!” ...(more by Einstein)

Richard Feynman: It is the facts that matter, not the proofs. Physics can progress without the proofs, but we can't go on without the facts ... if the facts are right, then the proofs are a matter of playing around with the algebra correctly. ...(more by Feynman)

Short Stories of Science and Invention

Weekly, from September 1942 to July 1945, Charles F. Kettering (who invented the first automobile self-starter) gave five-minute intermission talks about Science and Invention during the radio broadcasts of the General Motors Symphony of the Air. These radio talks are a fascinating legacy from the mind of a prolific inventor.

2022 Norse Gods Loki 2 Oz Silver - Cook Islands - Antiqued Stories About Chemistry

Henning Brand's “Philosopher's Stone”: There once lived in the Middle Ages in the German town of Hamburg a merchant by the name of Hennig Brand. We do not know how inventive he was in his trade operations, but can assert confidently that he had only a very crude idea of chemistry...
One fine evening the former merchant had a streak of luck. A substance, white as snow, settled at the bottom of his retort. It burned quickly, forming thick asphyxiating fumes. And the strangest thing was that it glowed in the dark. The cold light it gave off was so bright that Brand could read his ancient alchemical treatises by it (for him these treatises had now taken the place of business letters and receipts).

Perpetual Motion

Introduction: The history of the search for perpetual motion does not afford a single instance of ascertained success; all that wears any appearance of probability remains secret, and like other secrets, can not be defended in any satisfactory way against the opinions of the skeptical, who have in their favor, in this instance, an appeal to learned authorities against the principle of all such machines, and the total want of operativeness in all known practical results. Published statements afford sorry examples of talents and ingenuity strangely misapplied. Some, but very few, are slightly redeemed from contempt by a glimpse of novelty. Of genius all are deficient, and the reproductions of known fallacies show a remarkable ignorance of first principles on one side and of the most ordinary sources of information on the other. ...

Nature bears long with those who wrong her. She is patient under abuse. But when abuse has gone too far, when the time of reckoning finally comes, she is equally slow to be appeased and to turn away her wrath. (1882) -- Nathaniel Egleston, who was writing then about deforestation, but speaks equally well about the danger of climate change today.

Carl Sagan: In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' and then they would actually change their minds and you never hear that old view from them again. They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion. (1987) ...(more by Sagan)
