Today, I learned that:
We are in the middle of the Winter Olympic games and the Paraolympic games, but did you know that not only humans compete in skiing? Watch the video in reference #1 and marvel about what our AI friends can do!
On various occasions, I have told you the story about a new fantastic material called graphene. If you want to catch up on those, look at my posts from 2016-02-01, 2016-05-22, 2016-10-29, and 2017-06-23. And here comes another interesting fact from “down under”. Researchers in Australia have produced a very effective water filter using graphene film with microscopic nano-channels. When tested with the polluted waters in Sydney harbor, the result was so good that they could drink the water without any health issues. See more in reference # 2 below.
Finally, look at this amazing photo! It shows the light emitted by a single atom. More information can be found in reference #3 below.
The tiny dot in the center of the screen, between the two metal electrodes, is the light emitted by a single atom. Photo taken by quantum physics professor David Nadlinger, University of Oxford.
That’s what I learned in school !
