UPDATE: I’m hearing reports of calendar apps crashing quite severely. Please only experiment on non-vital apps as you could hypothetically lose data stored in them! But apparently if the app crashes and restarts don’t fix it: a forced restart will.

Proceed with caution, at your own risk, and report any findings!

CORRECTIONS
— At 01:51 I accidentally said “Senate” when I meant “Congress”. But on-screen it says “House Republicans” so I think it still makes sense despite my mis-speak.
— Let me know if you spot any more mistakes!

Thanks to my Patreons who mean I can keep throwing time and effort at videos about this election. And dont worry, I am a prudent spender of your money: that judges robe was hired not purchased outright. But I do now own the wig.

If youre a masters or PhD student from an ESA member state, and zero-g sounds like your thing, have a look at the Fly Your Thesis program: www.esa.int/Education/Fly_Your_Thesis — the 2017-18 submissions are closed, but that just gives you time to start planning for next year…

Сколько раз вы пытались понять квантовую механику? А сколько раз получилось? Наконец за объяснение взялся Дерек Маллер. Из видео узнаем, что там с параллельными мирами, сколько их может быть и еще раз попробуем вникнуть в то, что такое суперпозиция и квантовая запутанность.
