Ground was broken in by President Dwight D. Eisenhower when the Atomic Energy Act of authorized private nuclear power production in the U.

Su Lin died 1 Apr The True Adventures of Ruth Harkness Photon source Inin a letter published in Nature, G. Lewis coined the word "photon" when he suggested that it "would seem inappropriate to speak of one of these hypothetical entities as a particle of light, a corpuscle of light, a light quantum, or a light quant, if we are to assume that it spends only a minute fraction of its existence as a carrier of radiant energy, while the rest of the time it remains as an important structural element within the atom.

It would also cause confusion to call it merely a quantum, for later it will be necessary to distinguish between the number of these entities present in an atom and the so-called quantum number.

I therefore [propose for this] which is not light but plays an essential part in every process of radiation, the name photon.

Charles Dawson, steward of Barkham Manor, an attorney and secretary to the Sussex Archaeological Society; and Arthur Smith Woodward, keeper of geology at the British Museum announced their remarkable find had been made at Piltdown Common.

The specimen, known as Piltdown man, occupied an honored place in the catalogues of fossil hominids for the next 40 years. But inthanks to some rigorous scholarly detective work, Piltdown man was revealed to be nothing more than a forgerymanufactured from modern human and animal remains.

He was searching for missing cattle, following along the north side of the Mancos River when he came across site that he later named the Cliff Palace.

This launched his lifetime of further archeological exploration. These ruins of the largest and most famous cliff dwelling in North America, are now preserved in Mesa Verde National Park. In the s, the Anasazi, an ancient pueblo people, built rooms and 23 large, round kivas used for rituals within a large rock shelter, high on a cliff.

Wood pulp paper source Inpioneering samples of basswood pulp paper made by John Beardsley were reported in the New York Daily Times which reprinted an article from the Democrat newspaper of Buffalo, New York.

The article described three varied samples of the new paper that were shown to the editor of the Buffalo newspaper. Basswood is a tree of the linden family. Paper-making materials then in use included grasses, rag and flax. To transform wood into pulp, the cellulose fibres must be separated.

Beardsley used a mechanical means of revolving cutters. A later history of paper-making book stated that his results were not successful. Earlier patents had been issued to other inventors for the processing of wood pulp for paper.+ free ebooks online.
