A column of porous black graphite formed during the experiment. Carbon snake experiment. The carbon snake is a demonstration of the dehydration reaction of sugar by concentrated sulfuric acid. With concentrated sulfuric acid, granulated table sugar performs a degradation reaction which changes its form to a black solid-liquid mixture. [1]
Carbon disulfide (also spelled as carbon disulphide) is an inorganic compound with the chemical formula CS 2 and structure S=C=S.It is also considered as the anhydride of thiocarbonic acid. [8]
Emoto claimed that water was a "blueprint for our reality" and that emotional "energies" and "vibrations" could change its physical structure.

Homochirality is an obvious characteristic of life on Earth, yet extraterrestrial samples contain largely racemic compounds. [7] It is not known whether homochirality existed before life, whether the building blocks of life must have this particular chirality, or whether life must be homochiral at all.
[6] [8] Szilárd pointed out that a real-life Maxwell's demon would need to have some means of measuring molecular speed, and that the act of acquiring information would require an expenditure of energy. Since the demon and the gas are interacting, we must consider the total entropy of the gas and the demon combined.
Laboratory Life: The Social Construction of Scientific Facts is a 1979 book by sociologists of science Bruno Latour and Steve Woolgar. This influential book in the field of science studies presents an anthropological study of Roger Guillemin's scientific laboratory at the Salk Institute. It advances a number of observations regarding how ...
The journals are grouped into four main sections: Physical Sciences and Engineering; Life Sciences; Health Sciences; Social Sciences and Humanities.; Article abstracts are freely available, and access to their full texts (in PDF and, for newer publications, also HTML) generally requires a subscription or pay-per-view purchase unless the content is freely available in open access.
