British astronomer who was a pioneer
in radar and observational astronomy. During and after WW II he worked
with
R.A. Watson-Watt and then E.G.
Bowen to develop radar for uses in aerial combat. In the 1950s he applied
this experience to radio astronomy, developing radio-telescope technology
at Jodrell Bank Observatory and mapping stellar radio sources. He designed
a radio interferometer capable of resolving radio stars while eliminating
atmospheric distortion from the image (1952). With R.Q. Twiss, Brown applied
this method
to measuring the angular size of bright visible stars, thus developing
the technique of intensity interferometry. They set up an intensity interferometer
at Narrabri in New South Wales, Australia, for measurements of hot stars.«

Born 31 Aug 1913
Sir Alfred Charles Bernard Lovell was an English radio astronomer
who established
and directed (1951-81) Jodrell
Bank Experimental Station, Cheshire, England, with (then) the world's
largest steerable radiotelescope, now named after him Prior to WW
II, he worked at Manchester University on cosmic ray research. During the
war, he helped develop aircraft onboard radar systems. After the
war, to escape interference to radar equipment from city trams, he moved
his research to the University's more remote Jodrell Bank property. In
1946, he showed that radar echoes could detect optically invisible daytime
meteor showers. He gained funding to build the 250-ft-diam. telescope.
When completed in 1957, it was able to track the first artificial satellite,
Sputnik

American forensic scientist
who was most recognized for his contributions to the understanding and
control of alcohol impairment in traffic accidents, and who invented the
Breathalyser. He collaborated with Professor R.N. Harger of the Indiana
University School of Medicine in the introduction of the Drunkometer, the
first instrument for accurate measurement of quantities of alcohol in the
blood by breath analysis. Subsequently, he invented
the Breathalyzer, an instrument that changed the approach of forensic science
and police enforcement in response to drinking-and-driving problems. This
innovation enabled traffic enforcement authorities to determine and quantify
blood alcohol concentrations with sufficient accuracy to meet the demands
of legal evidence. |

Aug 1887; died 17 Sep 1958.
Austrian-British chemist
who improved methods in the 1920's to isolate and measure the minute
amounts of helium (as little as 10-10 cm3) slowly
released by traces of radioactive elements in rocks. This enabled determination
of both the age of rocks on earth, and also the age of meteorites which
implies the age of the solar system, (presently accepted as 4,600 million
years). Earlier, he and his friend George Charles de Hevesy introduced
radioactive tracer techniques (1912-13). Paneth used radium D as a tracer
to measure the solubility of lead salts, then extended the technique to
the study of the unstable hydrides of lead and bismuth. He contributed
to the study of the stratosphere by determining its composition as a function
of altitude up to 45 miles.«

Edward L(ee) Thorndike was a U.S. psychologist
considered to be the father
of Educational Psychology who studied the process of learning in animals,
children and adults. His theory of connectionism proposed that mental or
behavioral responses to specific stimuli are the result of a process of
trial and error that produces neural connections linking the stimuli with
the most satisfactory response. Thorndike studied how animals learn through
trial and error in his "puzzlebox" experiments, such as observing a hungry
cat in a box which received food when it escaped. Gradually, the animal
learned what it had to do to escape, and the escape time became shorter.
He applied such associative learning to humans and to the practice of education.« |

essay, The Question of Rest for Women during Menstruation. In this
work, she refuted allegations of the physical limitations of women, such
as published by Dr. Edward H. Clarke's in Sex in Education (1873).
She supported her position with scientific data including sphygmographic

Hermann Ludwig Ferdinand von Helmholtz was a German scientist who contribed
much to physiology, optics, electrodynamics, mathematics, and meteorology,
including the law of the conservation of energy (1847). He also developed
thermodynamics, in particular introducing concept of free energy. In 1850,
he measured the speed of a nerve impulse and, in 1851, invented the ophthalmoscope.
He discovered the function of the cochlea in the inner ear and developed
Thomas
Young's theory of colour vision (published 1856). His study of muscle
action led him to formulate a much more accurate theory concerning the
conservation of energy than earlier proposed by Julius
Mayer and James Joule.

Aug 1786; died 9 Apr 1889.
French chemist
who began the study of the chemistry of fats. He discovered fatty acids,
which led to a great improvement in the quality of stearine candles and
in the fats used to make soaps. Stearine was first described by Chevreul
in 1814 and was produced by heating glycerine with stearic acid. When used
in candles it gave a steadier, brighter, odourless light. He was the first
to find sugar in urine. He investigated and named margarine.
In physics, he introduced (1839) his attempt at producing a
systematic approach to seeing colours.
In his 90s he turned to the study of the psychology of the elderly. When
he died at 102, in his lifespan he had experienced both the French Revolution
and the building of the Eiffel Tower.

French physicist,
who developed the air thermometer - which relies on increase in volume

measure change in temperature in terms of a proportional change in pressure.
This observation led to the concept
of absolute zero in the19th century. Deaf since childhood, Amontons worked
on inventions for the deaf, such as the first
telegraph, which relied on a telescope, light, and several stations
to transmit information over large distances. Amontons' laws of friction,

upon by engineers for 300 years, state that the frictional force on a body
sliding over a surface is proportional to the load that presses them together
and is also independent of the areas of the surfaces. |

for Physiology or Medicine for the discovery
of acquired immunological tolerance to tissue transplants. He
studied the nature of antibody formation and immune processes and developed
the notion of immunological tolerance to explain why humans do not form
antibodies to their own bodily constituents. He also wrote about how mistakes
of the immune system might cause obscure forms of blood, liver and kidney
disease. He made pioneering use of fertile hen's eggs as hosts for virus
multiplication. The concepts he developed are part of the basis for current

Polish mathematician
who founded modern
functional analysis and helped develop the theory of topological vector
spaces. In addition, he contributed to measure theory, integration, the
theory of sets, and orthogonal series. In his dissertation, written in
1920, he defined axiomatically what today is called a Banach space. The
idea was introduced by others at about the same time (for example Wiener
introduced the notion but did not develop the theory). The name 'Banach
space' was coined by Fréchet. Banach algebras were also named after
him. The importance of Banach's contribution is that he developed a systematic
theory of functional analysis, where before there had only been isolated
results which were later seen to fit into the new theory. |

31 Aug 1937 (born 12 Apr 1849)
Swiss geologist
whose studies of the Swiss Alps greatly advanced knowledge of the dynamics
of mountain building and of glacial effects on topography and geology.
He studied the formation of overthrusts and nappes in the Alps. He supported
the idea of a contracting Earth. He also studied the mechanics of rock
deformation, proposing that rocks can deform plastically under pressure
and that the same pressure causes metamorphism. After a near-fatal fall
in the Alps during which he had a mystical experience, Heim began the first
serious study
of near-death experiences. Over a period of several decades he collected
observations and accounts from numerous survivors of serious accidents.
Heim first presented these findings at the Swiss Alpine Club in 1892. |

he stressed the use of experimental methods drawn from the natural sciences,
which he expanded and published as Lectures on the Mind of Humans and
Animals (1863). In his important work, Principles of Physiological
Psychology (1874) he maintained that psychology should investigate
the immediate experiences of consciousness, including sensations, feelings,
volitions, apperception, and ideas. His methods are still used in modern
psychophysical work, where reactions to external stimuli are measured in
some way, such as reaction time, reactions and comparison with graded colors

In 1993, a skin test for Alzheimer's disease was announced
from research led by Dr Daniel L. Alkon at the National Institutes of Health.
This disease gradually destroys memory, the ability to function, and is
eventually fatal. The benefit of the skin test, if validated by further
research, would be to differentiate the incurable Alzheimer's disease from
other more treatable forms of mental impairment. If effective, the test
would save hundreds of millions of dollars in diagnostic evaluations, though
several years of work remained before any clinical test would be widely
available. It was previously known that potassium channels closed in brain
cells affected by Alzheimer disease. The new test was designed to detect
if a similar collapse of potassium channels could be detected in skin tissues.«

In 1909, Nobelist Paul Ehrlich began the first chemotherapy (a term he

two organic arsenic compounds to test as a treatment for syphilis caused
by Treponema pallidum. That micro-organism could not be grown on
a culture medium, but Hata became the first to discover
how to infect rabbits to produce syphilis. After many careful experiments,
Hata reported success with "Preparation 606" (the 606th chemical devised
by Ehrlich's team). On 31 Aug 1909, Ehrlich watched Hata inject 606 into
a rabbit with syphilitic ulcers. The next day, no treponeme could be found,
and the ulcers healed within a month. Thus syphilis was the first disease
caused by a microorganism to be cured with a specific drug.«

and nearly all of its 14,000 chimneys were broken off at the roof. However,
geologically the most severe earthquakes in U.S. history had occurred earlier
in the century (16 Dec 1811). The epicenter then was in a sparsely populated
region and caused no known casualties, so the human consequences were relatively
not significant, although the violent movement of the ground changed the

| Curved stereotype
plates |
(source) |
In 1861, full pages of the New York Tribune were printed for the
first time in the U.S. using curved stereotype plates. Such plates were
first cast by Charles Craske in 1854 in New York City for a Hoe rotary
press. Stereotyping also enabled the publisher to make duplicate plates
for two presses which could half total production time to run an edition
with no extra costs in typesetting. Flat stereotyping had been used as
early as 1725 when William Ged took metal castings from plaster moulds
made from a frame of type, and in this way introduced a method for book
publishers to reduce wear on their type, and let the type itself be reused
for subsequent pages. Papier maché replaced plaster in the 1830's.
Craske extended the idea to making curved plates for rotary use.« [Image:

Board of Navy Commissioners with a more efficient organisation with true
division of labor among Navy Department employees. (The other bureaus were:
Naval Yards and Docks; Construction, Equipment, and Repairs; Provisions
and Clothing; and Ordnance and Hydrography.) Much of the impetus
for change was due to several scathing articles (Apr 1840 - Jun 1841) in

2,766). In 1838, Rugg had a blacksmith shop where with Martin Barnes,
he began making bolts and nuts for the market. Together, in 1840, they
established the first U.S. nuts and bolts factory in Marion, Connecticut.
It was a specially-designed one-story, 30 ft by 20 ft, wooden building
where with six employees, their capacity production was 500 bolts a day.
(Prior to 1838, when they started making bolts commercially, these articles
were hammered out and hand-finished by blacksmiths. An earlier but impractical
machinehad
been patented by David Wilkinson of Rhode Island on 14 Dec 1798.)  |

In 1836, a second U.S. patent was granted to one of the earliest African-American
inventors, Henry Blair, a free man of Glenross, Maryland, for a cotton
seed planter (No.
15). His first patent was for a corn planter (14
Oct 1834, No. X8447). Blair was born in Maryland about 1807 and lived
until 1860. He was a successful farmer
whose inventions met a need to increase efficiency in farming. His patents
were signed with a simple "X" because he had not learned to read or write.
Henry Blair was the second African-American to hold a patent. For some
time he had been regarded
as the first, until it became better known that the first African-American
on record to be granted a patent was Thomas Jennings for a "dry-scouring"
cleaning process (3 Mar 1821 No. X3306).« [Image:

In 1831, Charles Darwin was visiting
Maer Hall, home of his uncle Josiah Wedgwood II, whom he told of his father's
(Robert Darwin) opposition to him joining a two-year voyage on H.M.S.
Beagle. Charles was enthusiastic about the opportunity, but his father
objected to it as a waste of time, delaying his expected career in the
clergy, and would not give his permission. His father said, however, he
could be swayed to change his opinion, he said, if Charles found a man
with common sense who would regard the proposed trip as being worthwhile.
Charles found that man in his uncle Josiah, who wrote a letter to Robert,
answering all of the objections in his favour. Josiah was Robert's brother-in-law,
and as a family member was successful in influencing him to change his
mind.«

In 1625, the first patent for antifouling paint
was issued in Britain to William Beale (No. 32/1625)*.
