Rest in peace Phil Anderson, a giant on whose shoulders we stand

On Sunday March 29, Philip W. Anderson passed away.  Anderson is doubtlessly one of the greatest condensed matter physicists who ever lived.

Anderson made foundational discoveries in localization, high-temperature superconductivity and antiferromagnetism. Indeed, his achievements stretch beyond condensed matter; his work on spontaneous symmetry breaking contributed to development of the Standard Model of particle physics. I’m sure many more competent people will eulogize him, but I wanted share one specific personal connection I have to his work.

CVD success: Rep. Himes co-sponsors the Keep STEM Talent Act!

For the APS Congressional Visit Day last month, my team visited the DC office of Representative Jim Himes (D-CT-04) to advocate for a number of issues important to science (see previous post). One of our asks was for Rep. Himes to cosponsor the Keep STEM Talent Act. I just heard that Rep. Himes is now a cosponsor! Thanks so much to my CVD team, to Rep. Himes and to the staffer we met with, Jessica Hagens-Jordan!

APS Congressional Visit Day 2020

APS Congressional Visit Day 2020

This week, I am in Washington DC for the APS Congressional Visit Day and Annual Leadership Meeting. We started on Wednesday with the Congressional Visit. APS broke us up into teams by region. I’m a Massachusetts voter, so I joined a team of people from Massachusetts and Connecticut. We had six meetings with the offices of Massachusetts Senators Ed Markey and Elizabeth Warren, Connecticut Senators Chris Murphy and Richard Blumenthal along with House Representatives James Himes and Rosa DeLauro.

Outreach: The World in Your Classroom

Science is a powerful way of learning how our world works, but that knowledge is useless if ordinary people don’t trust scientists. This lack of trust is at the core of issues like climate change denial and the anti-vaccination movement. Scientific literacy is a huge and complex problem, but I think one cause of this mistrust is how few people know a scientist personally (in fact, one study found that only 4% of Americans could name a living scientist). People tend to trust people they know, so with that in mind I’ve decided to get more involved in science outreach.

I have now visited two local junior high school classrooms through The World in Your Classroom, a program that brings foreigners living in Taiwan into classrooms to meet with Taiwanese students and tell them about their home countries. I’ll describe one of those experiences now.

For the first thirty minutes or so I showed the students some slides talking about where I grew up and how I ended up in Taiwan. In advance, their teacher had sent me a list of questions from the students. They certainly knew a lot more about America than I knew about any foreign country when I was their age, and they weren’t afraid to ask the hard questions. Examples were “Do you support the US maintaining good relations with China?”, “Who did you vote for in the last presidential election?” and “What is your opinion on racism and same-sex marriage?”. Many of their questions asked whether America was friendly to immigrants, to which I said yes. (I imagine news coverage of current events might have inspired those questions). I did not talk extensively about my research, but I did talk about what it’s like to be a scientist and why I like my job. I especially wanted to address the misconception that scientists are all supergeniuses, so I made sure to point out that I was a very poor student when I was their age and I struggled quite a lot in school. They responded really well to this message.

For my trouble I was given a few small gifts, including a box of the best pineapple cakes I’ve had so far (I really need to figure out where those came from). I’m looking forward to meeting more Taiwanese students in the future.

The death of Le Grand K

Last Friday, the 26th General Conference on Weights and Measures voted to replace “Le Grand K”, the 129 year old physical prototype of the kilogram, with a new measure based on physical constants. The new definition, which comes in to force next spring, is now fixed by defining the Plank constant as exactly 6.626 070 15 x 10-34 Joule seconds. 

The kilogram was the last SI unit based on a physical prototype (which means that until next year, Le Grand K is, by definition, exactly one kilogram). Other prototypes, such as the physical meter, have been long since retired. This redefinition is a triumph of high-precision experimental physics. The problem with physical prototypes for units is that they can change. Le Grand K, for example, has been losing mass, to the tune of about 50 micrograms (5 parts in 100 million), possibly because the identical cylinders it is compared to have gotten dirty from being handled more often.

Farewell Le Grand K! Thank you for your service!

Keeping up with science policy

If you have three minutes every month to devote to keeping up with science policy, I highly recommend subscribing to APS’s Signal Boost. Signal Boost is a monthly video update about key developments in science policy. Among other things, they provide critical information on the budgeting process for science funding in the House and Senate along with how to contact your elected officials about each issue. Scientists are a small group, so we need to speak up to be heard.

This month: appropriations and a bill to fight harassment in STEM:

My first session with “Skype a Scientist”

A few months ago I signed up for Skype a Scientist, a service that connects scientists with classrooms around the world so students have a chance to meet a real scientist. Today I had my first session with a 7th grade IB class in Bangkok, Thailand. It was a lot of fun! I introduced myself and my field and talked a little bit about what it’s like being a scientist, then I answered questions from the students for the remaining time. There were all sorts of questions from “What challenges did you overcome to become a computational physicist?” to “Is the Earth’s magnetic field changing?”

If you’re a fellow scientist or a teacher who wants to skype a scientist you can sign up on their website: https://www.skypeascientist.com/ The commitment is small (you can sign up to do just one session) and there’s no need to prepare a lecture. I had a blast and I’m looking forward to more skype sessions!
