Project in Physics 105.3

Greek mathematician, physicist, engineer, inventor, and
astronomer. Although few details of his life are known, he is
regarded as one of the leading
scientists in classical antiquity.

Discovered that pressure
applied to an enclosed fluid
is transmitted undiminished
to every part of the fluid and
to the walls of its container
(Pascal's principle).

Made the first terrestrial measurement of the speed of light;
invented one of the first interferometers; took the first pictures of the Sun on daguerreotypes.

Co-discovered that intensity
of magnetic field set up by a
current flowing through a
wire varies inversely with the
distance from the wire.

2

The first American physicist; characterized two kinds
of electric charge, which he
named ``positive'' and
``negative''.

Developed hypothesis that
all gases at same volume,
pressure, and temperature
contain same number of
atoms.

Studied conditions that occur when an object moves
through a fluid at high
speed. Proposed ``Mach's
principle,'' which states that the inertia of an object is
due to the interaction between the object and the rest
of the universe .

Pioneer in study of electricity; invented the first electric
battery.

Proposed a simple geometrical
wave theory of light, now
known as ``Huygen's principle''; pioneered use of the pendulum in clocks.

Developed the fundamental
relationship of fluid flow
now known as Bernoulli's
principle.

Performed fundamental observations, experiments, and
mathematical analyses in astronomy and physics; discovered mountains and craters on
the moon, and other planets.

Discovered that current flow
is proportional to potential
difference and inversely
proportional to resistance
(Ohm's law).

Developed theories of gravitation and mechanics, and invented differential calculus.
Best known for his Three

Hypothesized foreshortening
of moving bodies (LorentzFitzGerald contraction) to
explain the result of the Michelson-Morley experiment.

more than one hundred patents and invented
countless unpatented inventions. In 1885,
George Westinghouse, head of the Westinghouse Electric Company, bought the patent
rights to Tesla's system of dynamos, transformers and motors. Nikola Tesla was Thomas Edison's rival at the end of the 19th century. In fact, he was more famous than Edison
throughout the 1890's.

A German-born theoretical physicist who developed the general theory of relativity, one of
the two pillars of modern physics (alongside quantum mechanics).
While best known for his mass–energy equivalence formula E = mc2 (which has been
dubbed "the world's most famous equation"),
he received the 1921 Nobel Prize in Physics
"for his services to theoretical physics, and
especially for his discovery of the law of the
photoelectric effect". The latter was pivotal in
establishing quantum theory.
