So, here is the presentation on light that I gave in class today.

May 4 is a special day for me!

YouTube – Fun Science: Light

Go watch and enjoy (and learn).

Thanks SO much to Alyssa for sharing!!

Do let me know if you see any vids that compliment our lessons in your youtubing of the internets.

NASA – A Supermassive Black Hole: “The colorful zigzag provides the evidence. If no black hole were present, the line would be nearly vertical. The Space Telescope Imaging Spectrograph measured a velocity of 880,000 mph within 26 light-years of the galaxy’s center. This measurement allowed astronomers to calculate that the black hole contains at least 300 million solar masses. “

Amazing!

We’ll talk more about photons and the Bose-Einstein Condensate in the Spring, but this is pretty exciting news…

New kind of light created in physics breakthrough – Technology & science – Science – LiveScience – msnbc.com: “Physicists have created a new kind of light by chilling photons into a blob state.”

Enjoy the break but don’t stop pondering!

Cosmonaut Sergi Avdeyev: By the time his stint in space was over, he had experienced 0.2 seconds less than the rest of the world did. This made him 0.2 seconds younger than he would have been if he had never gone into space. To put it in another way, he traveled 0.02 seconds into the future.

Quantum teleportation achieved over 16 km: “Scientists in China have succeeded in teleporting information between photons further than ever before. They transported quantum information over a free space distance of 16 km (10 miles), much further than the few hundred meters previously achieved, which brings us closer to transmitting information over long distances without the need for a traditional signal.”

Fascinating!
