Researchers create ‘thinnest possible’ LEDs at only three atoms thick

LEDs are already pretty tiny, but they just got a whole lot smaller. Researchers at the University of Washington have built what they say are the “thinnest-possible LEDs” — tiny lights that measure just three atoms thick. “Such thin and foldable LEDs are critical for future portable and integrated electronic devices,” Xiaodong Xu, co-author of a paper on the research that was published over the weekend in Nature Nanotechnology, says in a statement. At three atoms thick, the researchers’ LEDs are said to be 10 to 20 times thinner than conventional LEDs, opening up a number of potential new uses for them.

What number comes after a Googolplex?

A googolplex is 1010^100, where the exponents are solved from the right. The exponentiation symbol (^) means the number just to the left multiplied by the left number’s self the number just to the right number of times. If the left number is 10, that means 1 followed by the right number of zeros. That is 10googol=1010,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000. So the answer to your question is a-googolplex-and-1=(1010^100)+1.

Physicists invent flux capacitor, break time-reversal symmetry

In the popular movie franchise “Back to the Future”, an eccentric scientist creates a time machine that runs on a flux capacitor.

Now a group of actual physicists from Australia and Switzerland have proposed a device which uses the tunneling of around a capacitor, breaking time-reversal symmetry.

The research, published this week in Physical Review Letters, proposes a of electronic circulators, which are devices that control the direction in which microwave signals move.
