IST DIE QUANTENMECHANIK ODER DAS RECHNEN FUNDAMENTALER? Is quantum mechanics as currently conceived the ultimate theory of nature? In his book "Atomic Physics and Human Knowledge", Niels Bohr argued that because of the uncertainty principle quantum methodology might not be applicable to the study of the ultimate details of life. Delbruck disagreed, claiming that biosystems are robust to quantum disturbances, an assertion that is only partially valid rendering Bohr's argument still significant, even though normally ignored. The methods of the quantum physicist and of the biological sciences can be seen to involve two alternative approaches to the understanding of nature that can usefully complement each other, neither on its own containing the full story. That full story, taking into -
Isamu Akasaki(Professor at Meijo University
Nanotechnology and Materials (FY2016 update) Meeting the challenge of "impossible" technology Succeeded in the practical implementation of blue light-emitting diode! Research in the unattainable territory that won the Nobel Prize The 2014 Nobel Physics Prize was presented to blue LED. The development of blue LED resulted in the three researchers, Professor Isamu Akasaki, Professor commercialization of much brighter and energy-saving Hiroshi Amano and Professor Shuji Nakamura for the white light, thus contributing to energy conservation invention of an efficient blue light-emitting diode (LED). in the world and an improvement of people's lives in Red LEDs and yellow-green LEDs were developed in the areas without sufficient electricity. In addition to their 1960s; however, practical implementation of blue LEDs use as light sources, blue LEDs are now being widely was so difficult that it was even said that "it would be applied in various fields such as information technology, impossible to realize blue LEDs by the end of the 20th transportation, medicine and agriculture. Additionally, century." Amid such a circumstance, Professor Akasaki, the technology to put gallium nitride into practical Professor Amano and Professor Nakamura worked on implementation developed by the three researchers is the high-quality single crystallization and the p-type expected to find various applications in the future, such doping of gallium nitride (GaN), both of which had been as an application in power devices that serve as electric given up by researchers around the world. Their efforts power converters in electric vehicles and smart grids, from the 1980s to the 1990s finally led to their success next-generation power distribution grids,. -

“““Kings of Cool” Superconductivity Who are these people? SUPERCONDUCTORS An Introduction by Prof George Walmsley Normal conductor eg copper • Current, I. • Voltage drop, V. • Resistance, R = ? • Ans: V/I = R eg 2 Volts/1 Amp = 2 Ohms I Copper I V Normal conductor eg copper • Source of resistance: • Electron collides with lattice ion to produce heat (phonon). Copper lattice Lower Temperature • What happens when we cool a metal? • Ans 1: The electrons slow down and current is reduced maybe to zero.

William Bradford Shockley
William Bradford Shockley Born February 13, 1910, London, UK- died 1989, Santa Clara, Calif.; with Walter Brattain and John Bardeen, inventor of the transistor in 1947, the 1956 Nobel laureate. Education: BS, physics, California Institute of Technology, 1932; PhD, physics, MIT, 1936. Professional Experience: Bell Telephone Laboratories: member, Technical Staff, 1936- 1942 and 1945-1954, director, Transistor Physics Research Facility, 1954; director of research, Antisubmarine Warfare Operations Research Group, US Navy, 1942-1944; founder, Shockley Semiconductor Laboratory, 1954-1989; Stanford University: lecturer, 1958-1963, Alexander M. Poniatoff Professor of Engineering Science and Applied Science, 1963-1975, professor emeritus, 1975-1989. Honors and Awards: Nobel Prize in physics,1 1956. Co-inventor of the transistor in 1947 with John Bardeen and Walter Brattian, Shockley participated in one of the most important discoveries of the century. They applied for a patent in 1948; this device was described as a germanium “transfer resistance” unit, from which the name “transistor” was derived. Shockley continued his research on the device to create the germanium junction transfer transistor, which was much more reliable than the first unit. From this start he founded Shockley Semiconductor Laboratories in Santa Clara Valley in 1954. After he received the Nobel Prize in 1956, disenchantment with Shockley's management style and his propensity for pure research led to the defection of the “Fairchild Eight” in 1957, and the deterioration of his company. His controversial views on genetics and his racist theories have shocked the society around him, but he has continued his research into “grave world problems.” QUOTATION “The only heritage I can leave to Billy is the feeling of power and joy of responsibility for setting the world right on something.” (Shockley's mother, about her 8-year-old son) BIBLIOGRAPHY Biographical 1 Jointly with John Bardeen and Walter H. -

Proposed Changes to the SI , Their Impact on Fundamental Constants and Other SI Units
Proposed changes to the SI , their impact on fundamental constants and other SI units . < < >> >>>> >> Fundamental Constants Edwin Williams Planck constant, h,e LNE, Guest Scientist & NIST LNE CCM is asking: What system is best for the CCM and your metrology Community? The new SI in which we scale our system by fixing the values of e, h, NA and k provides: A system that is favorable to the mass community. Agreement with other measurements of h and NA. A system more stable over time and more suitable for the expression of the values of the fundamental constants. (P. Mohr) What is needed to implement the new system? Educate your community. Implement the changes required to be consistent with new values of h and NA . When? 2011 If 1ppm discrepancy resolved. Atomic mass and quantum electric standards are more stable, long term, than macroscopic mass standards What is the purpose of SI Provide a basis for a practical measurement system so that both science and industry can prosper We are being asked to simply choose the scales against which all measurements are made We still have the same metric system but it won’t drift and the scales will be clearer (have less uncertainty) Scientists can only disprove theories never prove them. The SI assumes that our present knowledge is valid but it is understood that the sciences upon which it is based must be tested. The SI simply provides a system where we can compare results from around the world. The adjustment of the fundamental constants is the most stringent test we make of the system. -
