ALICE detects the conversion of lead into gold at the Large Hadron Collider

AI to chemistry, scientists can perform virtual chemical experiments.

In such a scenario all antimatter would subsequently have annihilated itself with matter in the dense primeval gas, inundating the universe with high-energy photons. But there would be a small relic of matter left, no more than one part in a billion, which, almost as an afterthought, would make up the roughly 1050 tons of matter of which you and I

"Transmutation" is a term usually employed to designate the ancient art of the transmutation of metals--particularly of the base metals into gold.

in all, the model contains about twenty parameters, key numbers such as particle masses and force strengths, whose often surprising values are not predetermined by the theory but must be measured experimentally and inserted into the formulas by hand. Physicists usually refer to these parameters as constants of nature,

the three isotopes of hydrogen, only one, tritium, is radioactive—it decays into a stable isotope of helium.
