Adam Frank: Alien Civilizations and the Search for Extraterrestrial Life | Lex Fridman Podcast #455

Came to YouTube to watch a falling Slinky but now I guess I'm stuck here for 3 hours

This is the kind of enthusiastic, open-minded professor you HOPE to get for ANY class. You’ll never forget them, what they taught you, and most importantly, how to approach critical thinking so you KEEP LEARNING. That’s the gift.

Lex. Aliens. Sunday night. Lets roll.

Never heard of Mr. Adam Frank before, but I like this guy! He's very level headed yet still not afraid to appreciate the fun from multiple perspectives. Not a bit of the condescension that a large number of top scientists project. The type of teacher students aspire to learn from.

More than 3 hours and I never lost any attention. A rollercoaster of ideas

Best way to get people interested in what you’re talking about is to speak like you’re interested in it yourself! Gotta love the enthusiasm

I love this episode. As I grow older I see I'm falling more back into my 16 year old self. When I get home from work all I want to do is play video games and read/listen/watch stuff about space and aliens. This is all cool and peaceful for me.

Спасибо за новые переводы видео на русский язык! Пересматриваю их, и каждый раз нахожу для себя что-то новое. Лекс, респект и уважение

His passion on the subjects is clearly translated in his knowledge and enthusiam he has for a conversation with someone who has only a base knowledge on the subject. This man is a treasure, and an excellent ambassador for the subject
