Lab Tale of the Day

We recently changed the details of our MOT coils (OK, we had to. We messed around and there were … consequences. There was a shotgun involved, as it were) The old MOT coils were wound on a form, which held the wires in place. The new geometry is tighter and required something smaller, so we decided to go with no holder — the wires would be free-standing, but since they had adhesive on them, they would stick together. And we could coat them with epoxy, just to make sure.

But this still required something on which to wind the coils, and in machining terminology, such a device is called a mandrel. Which I immediately named “Barbara.”

Increasingly, The Answer is "No"

Aren’t We Clever?

“There is really no debate about climate change in China,” said Peggy Liu, chairwoman of the Joint U.S.-China Collaboration on Clean Energy, a nonprofit group working to accelerate the greening of China. “China’s leaders are mostly engineers and scientists, so they don’t waste time questioning scientific data.” The push for green in China, she added, “is a practical discussion on health and wealth. There is no need to emphasize future consequences when people already see, eat and breathe pollution every day.”

And because runaway pollution in China means wasted lives, air, water, ecosystems and money — and wasted money means fewer jobs and more political instability — China’s leaders would never go a year (like we will) without energy legislation mandating new ways to do more with less. It’s a three-for-one shot for them. By becoming more energy efficient per unit of G.D.P., China saves money, takes the lead in the next great global industry and earns credit with the world for mitigating climate change.

I don’t understand our hesitancy to go down the path of alternative energy. It seems like a no-brainer (making it a good match for many of our politicians) — we can become less dependent on foreign sources of energy, can create jobs here, and reduce CO2 emissions. Even if the bought-and-paid-for-by-big-oil politicians don’t like the last one, surely spending money domestically instead of sending it overseas has to be good for the economy. Waiting to act only makes things worse.

My Pen Crashed

The Pen That Never Forgets

The pens perform an interesting trick: when Dervishaj and her classmates write in their notebooks, the pen records audio of whatever is going on around it and links the audio to the handwritten words. If her written notes are inadequate, she can tap the pen on a sentence or word, and the pen plays what the teacher was saying at that precise point.

Dervishaj showed me how it works, flipping to her page of notes on exponents and tapping a set of numbers in the middle of the page. Out of a tiny speaker in the thick, cigar-shaped pen, I could hear her teacher, Brian Licata, explaining that precise problem. “It’s like having your own little personal teacher there, with you at all times,” Dervishaj said.

Fun to Imagine 1: Jiggling Atoms

Richard Feynman, one of America’s most renowned physicists, sits down in an armchair at his Californian home to explain the physics that underpins the world around us. In this first episode, he explores the beauty of the way atoms interact with each other and reveals why fires feel hot.

Boy drops DS in gorilla cage, inadvertently creates the best photo op ever

After reportedly being unable to figure out the confusing friend code system, the gorilla knocked it around and eventually lost interest.

The boy got his system back when a trainer lured the gorilla with an apple and was able to snatch the device out of the gorilla’s hands. It then grabbed a princess and jumped up a tower of ladders and construction beams before throwing down barrels of oil.
