Exploring the Nobel Mind: Unraveling the Legacy of Physicist Ivar Giaever
Ivar Giaever is a Norwegian-American physicist. He was awarded the Nobel Prize in Physics in 1973.
Life and Career
He was born on 5 April 1929, in Bergen, Norway. He earned his undergraduate degree in mechanical engineering from the Norwegian University of Science and Technology in Trondheim in 1952. He went on to work at the General Electric (GE) Research Laboratory in New York, where he made significant contributions to the field of superconductivity. In 1960, he established that tunneling also took place in superconductors. He conducted the experiment with a thin layer of oxide, coated with layers of superconducting metals. The experiment also demonstrated the existence of an energy gap, which is an energy range where no electron states can exist.
After that, he earned his Ph.D. in physics at the Rensselaer Polytechnic Institute in Troy, New York, in 1964. His thesis work focused on the properties of superconductors. In 1969, his interest turned to biophysics. On receiving Guggenheim Fellowship, he traveled to England and spent one year at Clare Hall, University of Cambridge, working on biophysics In 1970, he returned to the General Electric Research and Development Center, where he continued working on biophysics. In the following year, he began his work on the behavior of protein molecules at solid surfaces and the interaction of cells with surfaces.
Later in his career, Giaever became interested in climate change and became a vocal skeptic of the mainstream scientific consensus on the issue. He has made controversial statements about climate change, including denying the link between carbon dioxide emissions and global warming.
