Walkabout the Galaxy
Nobel Prize; black holes
Astrophysics and Astronomy | Physics
We celebrate the Nobel Prize in Physics for Roger Penrose and Andrea Ghez and Reinhard Genzel for discoveries about black holes, but Strange quark has some grievances to air about the Netflix show Away and Penrose's penchant for exclamation marks. We also see how the Sun is helping us better understand observations of distant stars and learn about the Astroquarks' very own satellite getting ready for launch.
The Hall Effect
It's late at night and you're all alone. All the doors are locked in an empty corridor. Then, one opens behind you, and from it emerges a terror you know you must flee as fast as you can. But as you try to run, your legs become sluggish and the hallway before you seems to stretch to infinity. That's the nightmare hall effect. So pinch yourself, and wake up from that bad dream and enjoy a nice DC voltage seemingly for free, with a capital H Hall Effect. Just cross a current with a magnetic field and presto, of H pops up orthoginal to the other two, giving you piece of mind and satisfaction that not only electromagnetism (Physics 2), but the world as a whole makes sense again. Leave those nighmare hallways behind and get your voltage going with the Hall Effect. The Hall Effect is not to be confused with the nightmare hall effect, the quantum hall effect, the spin hall effect, the quantum spin hall effect, or the anomalous hall effect. The Hall Effect, m'm m'm good. (Campbell's Soup)
