Video Title: (Interview With John Hall On Laser Measurement) Video Duration: 6:21 From: SPIETV Category: Science and Technology the winner of the 2005 nobel prize in physics reflects on a career spent with a fascination for lasers and science. john l. hall is a fellow and senior research ociate at jila, a joint insute of the university of colorado at boulder and the national insute of standards and technology. he was awarded the 2005 nobel prize in physics. hall is known as a pre-eminent laser experimentalist, concentrating on improving the precision and accuracy with which lasers can produce a specific, sharp frequency or color of light, and the stability to hold that frequency. his work has been essential to precision spectroscopy for physical and chemical annaysis, new tests and measurements of fundamental physical laws and constants, time and length, metrology and fiber-optic communications. in the 1960s he worked on the development of the methane-stabilized helium-neon laser, which became the cornerstone of a famous experiment at nist to measure the speed of light at least 100 times better than any previous determination. the work ultimately led to a fundamental redefinition of the meter, the basic unit of distance measurement. hall shared the nobel with theodor hänsch of the max planck insute for quantum optics and a professor of physics at ludwig maximilians university in munich, germany, and roy j. glauber, a professor of physics at harvard university. hall and hänsch were awarded half the nobel prize for their contributions to the development of laser-based precision ltbgt...lt bgt Tags: "Most Linked", Spie "spiegel", "spielaffe", "spie", "spiegel online", "spiele", "spiel", "spielberg", "spier", "spies like us", "", Spie Optics Photonics Lasers Jila Nist Nobel Frequency Comb Physics Science
Video Title: (Peter Heathfield - A Working Cl Hero) Video Duration: 4:07 From: solidaritet2010 Category: Nonprofits and Activism peter heathfield 2nd march 1929 4th may 2010 it is with deep regret that we note the death of former national union of mineworkers general secretary peter heathfield who ped away after a long illness on 4th may 2010. peter was a close ally of arthur scargill who along with mick mcgahey formed the heart of the leadership of the num during the miners' strike of 1984 85. like arthur, peter was vilified and slandered by the bourgeois media. roy greenslade, while editor of the daily mirror which was responsible for accusations of 'financial irregularity', was later to offer a public apology to both scargill and heathfield claiming he had been 'misled'. but the disgraceful role of the media was not forgotten or forgiven. peter said: "i never imagined i would have to face the kind of pressure that i experienced during the year-long strike, but the animosity and vilification that has emerged in large sections of the media during the past four months has been pretty overpowering." in the guardian obituary for peter it was noted that "it became obvious that there had been a deliberate attempt to vilify both num leaders" and "very possibly with some secret political involvement in a bid to finally discredit and destroy the union leadership." despite distasteful pressure put on peter by sections of the media later in his life to turn against his old comrades he adamantly refused to do so, regardless of the substantial amounts of money that was purportedly offered. peter and ltbgt...lt bgt Tags: "Top Favorites", Peter "peter andre", "peter graves", "peter gabriel", "peters of kensington", "peter pan", "peter pan bus", "peter alexander", "peter jackson", "peter jones", Peter Heathfield Working Cl Hero Num Slp
