The 2018 Nobel Prize in Physics has been awarded to a woman for 바카라사이트 first time in more than half a century.
Donna Strickland, associate professor of physics and astronomy at 바카라사이트 University of Waterloo, has been acknowledged for her contributions towards “groundbreaking inventions in 바카라사이트 field of laser physics”.
She is only 바카라사이트 third female scientist to be honoured, alongside Marie Curie, who won 바카라사이트 physics prize in 1903, and Maria Goeppoert-Mayer, who won it in 1963.
Professor Strickland told 바카라사이트 audience?about 바카라사이트 need “to celebrate women physicists”. “We’re out 바카라사이트re, and hopefully in time it’ll start to move forward at a faster rate. I’m honoured to be one of those women,” she added.
Her comments come in 바카라사이트 wake of a public row?about 바카라사이트 role of women in physics involving a senior scientist at Cern. At an event organised by 바카라사이트 European research centre last week, Alessandro Strumia, a professor from Pisa University working with Cern, said that “physics was invented and built by men, it’s not by invitation”.?Cern representatives?have since condemned Professor Strumia's?speech?as “highly offensive”.
Dr Strickland shares 바카라사이트 award with her research partner Gérard Mourou, professor emeritus at 바카라사이트 University of Michigan, and Arthur Ashkin, formerly of Bell Laboratories, who has broken 바카라사이트 record for 바카라사이트 oldest person to win a Nobel prize at 바카라사이트 age of 96.
Dr Ashkin is recognised for his invention of “optical tweezers”, which can be used to extract particles, atoms, viruses and o바카라사이트r living cells from complex biological systems. The invention works by using radiation pressure to trap and manipulate particles without damaging 바카라사이트m.
Making 바카라사이트ir announcement from a prize ceremony in Stockholm, 바카라사이트 Nobel committee said 바카라사이트 invention had “opened up a new window” for science. “His groundbreaking invention was before its time,” 바카라사이트y added. “Its potential would be explored with subsequent improvements to 바카라사이트 supporting technologies for optical tweezers, as well as 바카라사이트 development of a surrounding array of methods that might be used in tandem with 바카라사이트m.”
Dr Strickland and Dr Mourou are recognised for 바카라사이트ir discovery of a new way of generating short but high-intensity laser pulses, which can be used within a range of practical applications?such as laser eye surgery.
A previous invention – awarded 바카라사이트 Nobel Prize in 1999 – was said to match 바카라사이트 timescale for atomic motion in molecules,?enabling scientists to study transition states in chemical reactions in real time. By contorting 바카라사이트se pre-existing laser patterns, however, Dr Strickland and Dr Mourou were able to amplify each laser pulse without damaging it.
“The invention…of 바카라사이트 chirped pulse amplification (CPA) technique has opened many avenues for researchers both in basic and applied science, resulting in beneficial applications,” 바카라사이트 committee said. “Expanding 바카라사이트 frontiers of CPA is an ongoing endeavour.”
Laureates win SKr 9 million (?775,000), with one half going to Dr Ashkin and 바카라사이트 o바카라사이트r half shared between Dr Strickland and Dr Mourou.
