1 Ivar Giaever By: Matt VanDerWerff

2 Facts About Ivar -Born in Bergen, Norway on April 5, 1929 -Graduated in 1952 with degree in mechanical engineering -Giaever emigrated to Canada in 1954 -He obtained a Ph.D. in Physics in 1964

3 Fields Giaever Worked In -Thin Films-Thin material layers used in experiments -Tunneling-A particle can penetrate unexplored space regions -Superconductivity-Occurs in some materials at extremely low temperatures

4 Thin films -One micron thick -Conductive or dielectric (non-conductive) -Used in myriad applications

5 Tunneling -Quantum mechanics -Passing of particle through a seemingly impenetrable barrier -Without cause that is explainable by classical physics.

6 Superconductivity -Phenomenon observed in several metals and ceramic materials -When these materials are cooled to temperatures -They have no electrical resistance in this state

7 Other Fields -Solid State Physics -Biophysics

8 Biophysics -Discipline concerned applications principles physical sciences biological problems -Deals with biological functions depend on physical agents

9 Solid State Physics -Branch of physics concerned with experimental/theoretical investigations -Properties solids, such as superconductivity, photoconductivity, and ferromagnetism

10 Ivar Giaever on Global Warming -Not concerned about it’s effects -Thinks it is just a passing crisis fad -We will wait to see it gets worse

11 Greenhouse Gases -The atmosphere has a natural supply of greenhouse gases -They capture heat-without the greenhouse effect… -The planet would be an uninhabitable, frozen wasteland.

12 Global Warming -Too much greenhouse effect causes Global Warming -Global Warming heats up the planet -Melts ice and destroys arctic wildlife habitat

13 Prizes He Won -Oliver E. Buckley Prize combining tunneling and superconductivity -The 1973 Nobel Prize in Physics -Zworkin Award 1974
