Beyond awesome for so many reasons… Frothy Magnetic-Bubble Sea Found at Solar System’s Edge: “The edge of the solar system may be a frothy sea of giant magnetic “bubbles,” a new NASA study says. The new findings may mean that our system’s magnetic barrier—once thought to be a smooth shield—may be letting in more harmful [...]
Photos of a Neutrino Detector
Neutrinos are uncharged particles and are so light that, for decades, most physicists assumed they were actually massless. As if that weren't enough, they only interact with other matter via the weak force, which is only significant at short distances. Thus, for the most part, they generally pass through matter without incident—trillions go through your body every minute, but most of us will only have them hit anything a total of about three times in our entire lives.John Timmer, Ars Technica
So very cool… go look at the pics.
Bye Bye Comet!
Wow! Bye Bye Comet! [HD Video] | Flickr – Photo Sharing!: “SOHO watched as a fairly bright comet dove towards the Sun in a white streak and was not seen again after its close encounter (May 10-11, 2011). The comet, probably part of the Kreutz family of comets, was discovered by amateur astronomer Sergey Shurpakov. [...]
May 4 Light
Two years ago, I had my interview at the Day School and I used this as my teaching guide. I’m so happy it worked out So, here is the presentation on light that I gave in class today. May 4 is a special day for me!
Gamma Ray Bursts
Here’s the video we watched in class on a gamma ray burst… Gamma-ray bursts: Introduction to a Mystery: “Gamma-ray bursts are short-lived bursts of gamma-ray photons, the most energetic form of light. At least some of them are associated with a special type of supernovae, the explosions marking the deaths of especially massive stars. Video: [...]
Radio Waves and Planets
We’ll be covering the various parts of the Electromagnetic Spectrum in class this week, including radio waves… New radio wave technique could detect alien planets, receive interstellar tunes — Engadget: “So scientists at the University of Leicester in England developed a new approach: looking for radio waves emitted when ultraviolet flares light up the atmospheres [...]
Charlie on Light
I’m not jealous that he is a much better teacher than I am (yeah, right!), but I am jealous of his awesome editing skills… 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 [...]
New Electromagnet Record!
Collin and Anders set the bar(s) now with 170+ paper clips! Nice work, guys!
72 Paperclips!
After Collin busted the school electromagnet record with 61 paperclips, Christian magnetized a wrench and achieved 72 paperclips yesterday! Impressive!
