Physics Nobel awarded to Donna Strickland, third woman in history to win
Strickland, whose research helped advance the field of laser science, is the only living female Nobel laureate for physics.
- Strickland, a 59-year-old Canadian physicist, helped develop a technique that led to many laser technologies used today.
- Two other women have won the Nobel for physics; one in 1963, the other in 1903.
- Strickland shares the award and $1 million prize with two other scientists, Arthur Ashkin and Gerard Mourou.
The 2018 Nobel Prize in physics has been awarded to three physicists, including one female, for their work in advancing laser science. It marks the third time a woman in physics has won the award.
Donna Strickland, a professor at the University of Waterloo in Canada and self-described 'laser jock', shares the award and a $1 million prize with Arthur Ashkin, a retired American physicist, and Gerard Mourou, a professor at the École Polytechnique in France and University of Michigan.
In the 1980s, Strickland and Mourou developed a technique called chirped pulse amplification, which produces ultra-short and "ultra-sharp" laser pulses through a three-part process that involves stretching, amplifying and compressing a laser beam. The pair outlined their landmark research, which led to the development of many medical tools including those used to perform laser eye surgery, in a 1985 paper. It was Strickland's first time being published.
Ultra-sharp laser beams make it possible to cut or drill holes in various materials extremely precisely – even in living matter. Millions of eye operations are performed every year with the sharpest of laser beams.#NobelPrize pic.twitter.com/MiYb4i8AHw

Female laureates: A very short list
Strickland, who's the only living female Nobel laureate for physics, said it's crazy to think she's only the third woman to have won the prize, the other two being Maria Goeppert-Mayer, who won in 1963 for her work on atomic structure, and Marie Curie who won in 1903 for her research into radioactivity.
"We need to celebrate women physicists because we're out there, and hopefully in time it'll start to move forward at a faster rate. I'm honored to be one of those women," she said in a phone interview with the Royal Swedish Academy.
Strickland wasn't the only scientist surprised by the very short list of female laureates in physics.
"The most thrilling thing for me is to see Donna Strickland share this year's prize," Jim Al-Khalili, professor of theoretical physics at the University of Surrey, told The Guardian. "It is quite shocking to know that she is only the third woman to win a physics Nobel ever... It is also quite delicious that this comes just a few days after certain controversial and misogynistic comments made at a conference at CERN about women in physics."
Al-Khalili was referring to comments made by Alessandro Strumia of Pisa University during a presentation he gave at CERN, the nuclear research center and particle accelerator in Geneva, in which he said physics was "invented and built by men, it's not by invitation."
To create wiser adults, add empathy to the school curriculum.
- Stories are at the heart of learning, writes Cleary Vaughan-Lee, Executive Director for the Global Oneness Project. They have always challenged us to think beyond ourselves, expanding our experience and revealing deep truths.
- Vaughan-Lee explains 6 ways that storytelling can foster empathy and deliver powerful learning experiences.
- Global Oneness Project is a free library of stories—containing short documentaries, photo essays, and essays—that each contain a companion lesson plan and learning activities for students so they can expand their experience of the world.
Philosophers like to present their works as if everything before it was wrong. Sometimes, they even say they have ended the need for more philosophy. So, what happens when somebody realizes they were mistaken?
Sometimes philosophers are wrong and admitting that you could be wrong is a big part of being a real philosopher. While most philosophers make minor adjustments to their arguments to correct for mistakes, others make large shifts in their thinking. Here, we have four philosophers who went back on what they said earlier in often radical ways.
The inequalities impact everything from education to health.
Astrophysicist Michelle Thaller talks ISS and why NICER is so important.
- Being outside of Earth's atmosphere while also being able to look down on the planet is both a challenge and a unique benefit for astronauts conducting important and innovative experiments aboard the International Space Station.
- NASA astrophysicist Michelle Thaller explains why one such project, known as NICER (Neutron star Interior Composition Explorer), is "one of the most amazing discoveries of the last year."
- Researchers used x-ray light data from NICER to map the surface of neutrons (the spinning remnants of dead stars 10-50 times the mass of our sun). Thaller explains how this data can be used to create a clock more accurate than any on Earth, as well as a GPS device that can be used anywhere in the galaxy.
Just before I turned 60, I discovered that sharing my story by drawing could be an effective way to both alleviate my symptoms and combat that stigma.
