Summary
What does it mean for an electron to spin? Why do we have such a hard time measuring it? And why doesn’t Paul Dirac get any attention anymore, anyway? I discuss these questions and more in today’s Ask a Spaceman!

| 0:00.0 | You know what time it is. It's time for Ask a Space Man. I'm your host, Paul Sutter. You've got questions and I've got answers. You know how the show works, but let's take it for another spin. You go online, Twitter, Facebook, user the hashtag Ask a Spaceman.. Send me some questions, and I will pick a small subset of them to answer on this show |
| 0:25.5 | only because there's a lot of questions and not a lot of shows. |
| 0:29.3 | I got to work on that. |
| 0:31.0 | You can also email me directly at Ask a Spaceman at Gmail.com. |
| 0:34.8 | You can also go to Ask aSpaceman.com or YouTube.com slash Paul M. Sutter to check out the videos. |
| 0:41.6 | All those places can accept questions. |
| 0:44.3 | How awesome is that? |
| 0:46.4 | We have one simple goal with this show. |
| 0:49.4 | Complete knowledge of time and space. |
| 0:51.4 | And on the road to complete knowledge of time and space we have today's |
| 0:54.8 | questions from so many people asking the same question this is fantastic we've got dean b via email |
| 1:01.3 | what is fundamental spin we've got p e via email how does an electron have quote unquote spin we've got at |
| 1:09.8 | nirb nirb nirs on Twitter. Could you explain once |
| 1:14.8 | and for all what does the spin property mean in quantum mechanics? We've got Carrie Kale via |
| 1:20.3 | email. Why are so many things spinning? Where does that energy come from? We've got at |
| 1:24.9 | sojournal via Twitter 10 bucks. if you can explain the spin of the |
| 1:31.2 | electron. Now, I don't often take bets, but you know what? At sojournal, as you're listening to me, |
| 1:38.1 | prepare an envelope. I want you put on that envelope the address, Paul M. Sutter, P.O. Box 3322, |
| 1:43.7 | Columbus, Ohio, 43210- dash 3322 you can put that 10 |
| 1:48.7 | dollars in that envelope because i think at the end of today you're going to owe me 10 bucks |
| 1:56.0 | i think we're going to do it we're going to do quantum spin to your satisfaction i'm quantum spin to your satisfaction. I'm laying it out there. |
| 2:02.4 | I'm laying it out there. I haven't even recorded. I don't know how well this is going to turn out, |
