Wilhelm Konrad Rontgen (1845-1923) published a report in 1895, which described his discovery of a mysterious source of energy emitted by a cathode ray tube.This source of energy caused barium platinocyanide coated on paper to luminance.The French physicist Antoine Henri Becquerel (1852-1908) wondered if X rays might be among the energy given off by fluorescent materials.In 1896 Becquerel discovered that potassium uranyl sulfate (K2UO2 (SO4)2 did create energy that penetrated black paper to expose photographic film.Even so, early work done by Bertram Borden Boltwood (1870-1927), an American chemist and physicist demonstrated several important consistencies.First, the same Pb/U ratios are obtained in samples from the same geologic age.

Furthermore, the formation of the daughter isotope is exponential and inverse to the parent decay.

To his surprise the compound could do this even when it was not fluorescing.

This energy did not only have penetrating power it also ionized the air as shown by an electroscope.

Second, atoms of radioactive elements are unstable and spontaneously decay to other elements by the emission of alpha and beta particles.

Thus the transmutation medieval alchemist desired was in fact being done by nature continuously.

  1. Szpilman, who died three years ago, was an artist of sterling pedigree, which all but guarantees his recordings won't be a redux of the David Helfgott-style compromised pianism heard in the wake of the 1996 film Shine.
