Scientists, Effects, and Principles

 

Our scientist for the week is Albert Einstein. He is famous for his special, and general, theories of relativity and the mass energy equivalence equation E=mc2 where E is energy, m is mass, and c is the speed of light. In the MKS measuring system energy is in joules, mass is in kilograms, and the speed of light is in meters/second. He won the Nobel prize for work in quantum physics showing that photons of light can react with some materials by knocking electrons from their surface; ie The Photoelectric Effect. Solar cells produce electricity with this process. He has a very big place in the Science Hall of Fame! Click here to see a some of his discoveries.

Werner Heisenberg (5 December 1901 – 1 February 1976) was a German theoretical physicist who made foundational contributions to quantum mechanics and is best known for asserting the uncertainty principle of quantum theory. In addition, he made important contributions to nuclear physics, quantum field theory, and particle physics.

Heisenberg, along with Max Born and Pascual Jordan, set forth the matrix formulation of quantum mechanics in 1925. Heisenberg was awarded the 1932 Nobel Prize in Physics.

Following World War II, he was appointed director of the Kaiser Wilhelm Institute for Physics, which was soon thereafter renamed the Max Planck Institute for Physics. He was director of the institute until it was moved to Munich in 1958, when it was expanded and renamed the Max Planck Institute for Physics and Astrophysics.

Heisenberg was also president of the German Research Council, chairman of the Commission for Atomic Physics, chairman of the Nuclear Physics Working Group, and president of the Alexander von Humboldt Foundation.

Many physicists have been working on linking the large scale work (The Big Bang) of scientists like Einstein, and the micro world of Heinsenberg, to come up with a unified field theory to explain what seems to be too diferent to imagine.

Heinrich Hertz, a German physicist, applied Maxwell's theories to the production and reception of radio waves. The unit of frequency of a radio wave -- one cycle per second -- is named the hertz, in honor of Heinrich Hertz.
Hertz proved the existence of radio waves in the late 1880s. He used two rods to serve as a receiver and a spark gap as the receiving antennae. Where the waves were picked up, a spark would jump. Hertz showed in his experiments that these signals possessed all of the properties of electromagnetic waves.
With this oscillator, Hertz solved two problems. First, timing Maxwell's waves. He had demonstrated, in the concrete, what Maxwell had only theorized - that the velocity of radio waves was equal to the velocity of light! (This proved that radio waves were a form of light!) Second, Hertz found out how to make the electric and magnetic fields detach themselves from wires and go free as Maxwell's waves.

You could find a place in the "Science hall of Fame" by anything from entering science fairs, to formulating "thought problems" like Albert Einstein did. You don't need millions of dollars to come up with a new concept in Science!!!
