Rutherford was the greatest of the pioneers of subatomic physics; he
"led us to the confines of knowledge in respect of the ultimate
structure and constitution of matter."
Teller, Edward (1908- ):
Hungarian born physicist, who studied under
Niels
Bohr at Copenhagen. Leaving Germany in 1933, Teller was to lecture both
at London and at Washington (1935). During the war years he was to join Oppenheimer's
theoretical study group at Berkeley, California. Teller was instrumental in
the development of the first earthbound thermonuclear explosion. He
repudiated, as a scientist, any moral implications of his work, indeed, it
is reported (Chambers) that he thought that but for
Oppenheimer's qualms, the United Sates might of had the hydrogen bomb by
1947.
Torricelli, Evangelista (1608-47):
Italian scientist who was to become a helper (amanuensis) to
Galileo.
Upon Galileo' death, in 1642, Torricelli was to take a position at the
Florentine Academy. We will always know him for the invention of the "Torricellian
tube." It was on account of Torricelli's experiments that we were to
come to better under stand the nature of atmospheric pressure, for example,
it was Torricelli who first determined that water will not rise above 33
feet in a suction pump. So, too, it is to Torricelli that we owe the first
statement of the principles of hydro mechanics. His efforts also led to
considerable improvements to both the telescope and microscope. First and
foremost, however, Torricelli was a mathematician and he is credited with
"several mathematical discoveries."
Tyndall, John (1820-93):
Tyndall is tagged as an English physicist, lecturer and writer. He
collaborated with
T.
H. Huxley in certain of his scientific studies. A classic, is Tyndall's
book, Fragments of Science. I am fortunate, in addition, to
have, in my library, Tyndall's Six Lectures on Light (London:
Longmans, Green; 1885).
Venturi, Giovanni Battista (1746-1822):
Italian physicist, who determined that "a short constriction in a
tube between two longer tapered portions that are usually of unequal
length but terminate with the same diameter, so that there is a drop in
pressure in a fluid flowing through the constriction which may be used to
determine the rate of flow or used as a source of suction; also devices
having this form and the effect involved." (OED.)
Another way of putting it, is, that the speed of a fluid flowing through a
tube can be accelerated by introducing a tapering constriction into the
flow path.
Bernoulli’s
principle tells us that Venturi’s constriction will also lower the
fluid pressure, since an increase in velocity must lead to a decrease in
pressure, and, for all you cottager's out there, this is the principle
behind the jet pump.
Volta, Alessandro, Count (1745-1827):
Volta was the Italian physicist which will always be remembered by the
label "volt," one applied to describe a unit of electric
pressure. It was Volta who developed the theory of current electricity;
further, that water might be decomposed through the application of
electricity; and further, he invented the electric battery.
Wallis, John (1616-1703):
Wallis, the English mathematician, was to see to the publication of his
work, Arithmetica Infinitorium. In it will be found Wallis'
pioneering work which "presaged the calculus and the binomial theorem
and a value for Psi."
Watson, James Dewey (b.1928):
Watson made his reputation in the field of genetics. He was born in
Chicago, and, at the age of 15, he was admitted to the University of
Chicago, graduating in 1947. At Indiana, he finished his Ph.D. in Genetics
(it is interesting to note that both Cal. Tech and Harvard turned him down
for their graduate programs). In 1950, Watson joined Cavendish Laboratory
at Cambridge, England; there to meet and work with such people as
Francis
Crick, and others, who were trying to determine the makeup of DNA (Deoxyribo
Nucleic Acid). Thus it was, that Crick and Watson made their big discovery,
viz. that DNA was a winding helix in which pairs of bases held the strands
together. This model of the DNA double helix formed the basis of important
research in the areas of Biochemistry and Molecular Genetics. In 1962,
Watson and Crick, together with Maurice Wilkins, were awarded the Nobel
Prize. In 1976, Watson was to become the full-time director of Cold Spring
Harbor Laboratory (Long Island, New York), which to some, came as a surprize,
as he had, by then, established the image of the "Nutty
Professor." At the Cold Spring Harbor Laboratory, Watson made important
contributions to the understanding of genetic code. In 1988, Watson's
achievement and success led to his appointment as the Head of the Human
Genome Project at the National Institute of Health, a project which turned
out to be the most determined and most generously funded effort in biology.
Wöhler, Friesrich (1800-82):
Wöhler, born near Frankfurt and educated at Heidelberg, was to become a
professor at Göttingten in 1836. Wöhler's work led to him isolating
aluminium. "His synthesis of urea from ammonium cyanate in 1828
revolutionized organic chemistry."
