| 0:00.0 | The following is a conversation with David Kipping, an astronomer and astrophysicist at Columbia University, |
| 0:06.4 | director of the Cool Worlds Lab, and he's an amazing educator about the most fascinating scientific |
| 0:13.6 | phenomena in our universe. I highly recommend you check out his videos on the Cool Worlds YouTube |
| 0:20.2 | channel. David quickly became one of my favorite human beings. I hope to talk to him many more times |
| 0:26.8 | in the future. And now a quick few second mention of each sponsor. Check them out in the description. |
| 0:32.8 | It's the best way to support this podcast. We got Simplestafe for Home Security, Shopify for |
| 0:38.6 | e-commerce, and ExpressVPN for privacy on the internet. She's wise to my friends. And now onto |
| 0:45.7 | the full adries. As always, no ads in the middle. I find those annoying. So I try my best to make sure |
| 0:52.4 | we don't have any. But if you skip these, please still check out the sponsors. I mean, without them, |
| 0:59.7 | this podcast would not be possible. So it's a huge, huge thank you to them for believing this |
| 1:04.4 | podcast, for supporting it. And they make good stuff, which is the reason why they're a sponsor. |
| 1:09.8 | So maybe you might consider checking out their stuff. Maybe it will make you feel good as well. |

| 1:22.2 | I don't remember at this point how long it took me to set it up. But it must have been certainly |
| 1:27.2 | less than an hour, it's probably like 30 minutes. Everything just works. Everything's connected. |
| 1:32.3 | All the sensors are amazing. Just super easy to use. And I think that first layer of security |
| 1:37.2 | of physical security is essential. I take my security extremely seriously. There's many, many layers |
| 1:43.2 | of both physical and digital security. And I think it's just taking security seriously allows you |
| 1:51.3 | to kind of take control of your life and take responsibility for being in this world, |
| 1:56.8 | at world that's sort of full of dangers and risks and all that kind of stuff. And it's just really |
| 2:02.0 | empowering. Just like discipline is freedom. I think in that same way in taking your security |
| 2:09.0 | seriously is the kind of freedom because it gives you freedom to take on the day. |
