It was the Nobel Prize announcement that launched a thousand "How many physicists does it take to change a light bulb?" jokes on twitter. (I know, we all thought we were being totes original.) The Nobel Prize committee awarded this year's prize in physics to Isamu Akasaki, Hiroshi Amano and Shuji Nakamura, who produced blue light beams from semi-conductors in the early 1990s -- i.e., blue light-emitting diodes (LEDs). Until then, we could create red and green light, but blue remained elusive. The Nobel-Prize-Winning Tech Helped Enabled Mobile Computing, Highly Efficient Lighting. The blue LED might save more energy than just about any other technology. But there's a dark side to LED lighting too, according to New Scientist.

It might not sound impressive, but the physics behind it — and the power of its applications — are literally world-changing. Weird factoid: One of the Nobel Prize-winning physicists only got $200 for his invention. Chad Orzel offered a handy background explainer on the physics of blue LEDs. Also, apparently blue LEDs are good for prizes, but bad for insects: "traps placed near LEDs captured 48% more insects than traps near sodium-vapor lights."

Depending on your perspective, physics also horned in on this year's Nobel Prize in Chemistry for Improving Microscopes. Eric Betzig of Howard Hughes Medical Institute, US, Stefan Hell of the Max Planck Institute for Biophysical Chemistry, Germany, and WE Moerner of Stanford University, US, shared the prize for ‘the development of super-resolved fluorescence microscopy,’ which made it possible to see single molecules.

Even though Alfred Nobel was an inventor, fundamental discoveries have won more Nobel Prizes. And maybe that's OK, says science writer George Johnson. There was also the usual post-game analysis on all the deserving scientists who haven't won. For instance, National Geographic highlighted 10 Huge Discoveries Without a Nobel Prize.

Women were sadly lacking representation in this year's crop of Nobel Prizes (excepting the Peace Price) -- and no woman has won the physics prize in over 50 years, despite the fact that there are plenty of excellent candidates. Slate weighed in with a list of several Women Who Deserve a Nobel Prize in Physics. "The women on this list have collectively received almost every honor available to scientists. But despite the recent proliferation of scientific awards, including some with purses larger than the Nobel, the prize established in 1895 by the Swedish dynamite inventor still carries unrivaled cachet both within science and among the public. It’s time for the Nobel Committee to recognize some of the great women who have pushed their way into a nearly all-male world and, in the process, pushed physics forward. Give some of them the prize already!"

On the lighter side, here's What It’s Like to Carry Your Nobel Prize through Airport Security, courtesy of 2011 Physics Nobel Laureate Brian Schmidt, who brought his medal with him to show his grandmother in Fargo, North Dakota and ran afoul of the TSA on his way back to Australia.

They said, ‘What’s in the box?’

I said, ‘a large gold medal,’ as one does.

So they opened it up and they said, ‘What’s it made out of?’

I said, ‘gold.’

And they’re like, ‘Uhhhh. Who gave this to you?’

‘The King of Sweden.’

‘Why did he give this to you?’

‘Because I helped discover the expansion rate of the universe was accelerating.’

At which point, they were beginning to lose their sense of humor. I explained to them it was a Nobel Prize, and their main question was, ‘Why were you in Fargo?’”

J. Robert Oppenheimer jumps for photographer Philippe Halsman's 1952 "Jump Book," inspiring an article on the kinematics of jumping. Image source:

Addressing the Kinematics and Dynamics of One-Dimensional Motion: Jumping in the July 1970 issue of the American Journal of Physics. "[Elmer] Offenbacher relates a famous photo of Robert Oppenheimer jumping for Philippe Halsman's Jump Book (1952) which was a book by the great photographer of images of people jumping. And jump Oppenheimer did--one of the best jumps in the book, a jump reaching for something with an outstretched finger, coat open and flying, a big effort, jumping for something.... [T]he notion of jumping and relating it to physics with a picture of Oppie got students to think about the kinematics and dynamics of one-dimensional motion."

Physicist Brian Cox: "Why’ questions always fail, scientifically. Why does that object fall to the ground? Because of the force of gravity. Why is the gravity there? Because of the curvature of space-time. Why does it…?” Cox rolls a hand in the air, suggesting endless questions. “In the end you always get to I don’t know. Science is really about ‘how’.” He takes a bite of his pastry. “But with cosmology you do tend to start to touch on these ‘why’ questions."
