Nobel Prize for Blue LEDs

Alfred Nobel's signature in blue LED's. From the Nobel Prize Twitter feed.

The 2014 Nobel Prize in Physics has been awarded to Isamu Akasaki, Hiroshi Amano and Shuji Nakamura for the development of blue LED’s. As always, this is kind of fascinating to watch evolve in the social media sphere, because as a genuinely unexpected big science story, journalists don’t have pre-written articles based on an early… Continue reading Nobel Prize for Blue LEDs

Nobel Season 2014

With this morning’s announcement of the 2014 Nobel Prizes in Physiology or Medicine, the annual Nobel season is upon us. I didn’t do a betting pool post this year, because when I announced last year’s winner, I was reminded that I had never paid off the prize to the previous year’s winner. So I think… Continue reading Nobel Season 2014

Yes Virginia, There Are Quantum Jumps

Quantum jumps, from the Wineland group paper described in the text. The top is a mercury ion with just the 194nm laser, the middle a single ion with both 194nm and 281nm lasers, and the bottom two ions in the same trap with both lasers.

In a weird coincidence, shortly after I wrote a post about “quantum leap” as a metaphor, I was looking up some stuff about John Bell and ran into mentions of a paper he wrote called “Are There Quantum Jumps?” Bell is borrowing a title from Schrödinger, who wrote a pair of articles (really, one article… Continue reading Yes Virginia, There Are Quantum Jumps

Eureka Publicity: Blurbs and Talks

Cover for the book-in-progress.

Eureka: Discovering Your Inner Scientist has officially been sent to the printers, so we’re at the phase of things where I don’t have anything to do but think about publicity. There are some reviews forthcoming, at least one of which I’m very happy about, but I’ll share more about that when it becomes public. I’ve… Continue reading Eureka Publicity: Blurbs and Talks

Metaphors and Style

Two language-related items crossed in the Information Supercollider today: the first was Tom’s commentary on an opinion piece by Robert Crease and Alfred Goldhaber, the second Steven Pinker on the badness of academic writing. All of them are worth reading, and I only have small dissents to offer here. One is that, unlike Tom and… Continue reading Metaphors and Style

Finding Extrasolar Planets with Lasers

Cartoon representation of a frequency comb, from one of my papers.

On Twitter Sunday morning, the National Society of Black Physicsts account retweeted this: Using Lasers to Lock Down #Exoplanet Hunting #Space http://t.co/0TN4DDo7LF — ✨The Solar System✨ (@The_SolarSystem) September 28, 2014 I recognized the title as a likely reference to the use of optical frequency combs as calibration sources for spectrometry, which is awesome stuff. Unfortunately,… Continue reading Finding Extrasolar Planets with Lasers

Trains of Clocks

Students at work on the trains-of-clocks demo.

My Gen Ed relativity course has mostly been me lecturing about stuff to this point, so on Wednesday I decided to shake things up a bit and convert a chapter of David Mermin’s It’s About Time. The idea was to get students up and moving around a bit, and actually making some measurements of stuff.… Continue reading Trains of Clocks

On Putting Words in Einstein’s Mouth

Screen shot of my TED-Ed video mentioning Einstein.

Modern media being what it is, I should get out in front of this, so: I am guilty of putting words in Einstein’s mouth. I mean, go watch my TED-Ed video on particles and waves, or just look at the image up top– that very clearly shows Einstein saying words that he probably never said.… Continue reading On Putting Words in Einstein’s Mouth

The Edge of the Sky by Roberto Trotta

I get a fair number of books to review, but I’m often pretty bad about writing them up in a timely manner. Of course, most of them are well over 70 pages long, which is why I’ve managed to turn around Roberto Trotta’s The Edge of the Sky: All You Need to Know About the… Continue reading The Edge of the Sky by Roberto Trotta

Uncertain Dots 22

After a long absence due to travel (some of which is discussed), Uncertain dots returns! Rhett and I talk about recent travels, how people going into internet-based physics outreach these days would probably do better to make videos than blog, physics in science fiction, celestial navigation, and as always, our current courses. Some links: —… Continue reading Uncertain Dots 22
