who just decided to start studying space like me? <3
Oh yes big daddy astronomy, put me in my place
three minutes in and the existential crisis strikes
I want to be an astronomer when I grow up. I'm not sure if that means writing books, or teaching a class, or working in an observatory, but I just want to be able to learn about the universe and then teach it to other people. I'm not sure if I'll actually be able to DO that, but I'll just have to see how life goes and learn what I can for now. Thanks for this Crash Course!
Me: [starts the astronomy playlist] This is big brain time
I started crying in the end I don't know why, but it's so touching I love knowledge, I love science I love learning about new things and the world It's just so fascinating😭
As a kid in a country like Afghanistan it's been always a big dream of mine to learn about the cosmos and become an astronomer. I remember every summer night which I was sleeping outside on the balcony, I was staring at the sky for hours and I was amazed (and still I am) by the world up there. As the time went on and I grew up, specially in the last years of my school I realised that in order to make a living for myself and for my family I've to study sth. which I could find a job in the future in a country like Afghanistan. So I decided to Study Civil Engineering; right now I'm doing my postgraduate studies in Civil Engineering in Germany. But still I couldn't forget about my dream and even today astronomy is my passion and who knows may be this video was a kick off to start with it. And I'm sure I am going to start learning about the universe seriously. one day.....
Anyone in 2024?
"the fault in astrology lies within ourselves and not in our stars" I see what you did there. Clever
I'm actually really looking forward to this. :]
This dude's voice is so awesome it's now going to replace my brain's narration voice, so I can hear him explain everything I do. "ManToast, feeling more creative today than usual, decided to combine his coffee with the hot chocolate he forgot he kept in the back of his cupboard, thus creating a mediocre, yet still satisfying, Mocha coffee." It's not weird, I promise.
his 'astronomy puts you in place speech' intensified my existential crisis
"Understanding that our understanding might be wrong is essential, and trying to figure out the ways we may be mistaken is the only way that science can help us find our way to the truth." My, that's deep.
Awesome presentation. I can only hope Neil DeGrasse Tyson makes a guest appearance in future episodes. Phil Plait does an absolutely outstanding job presenting here. The pacing felt just right. I would love to just listen to a conversation between Neil and Phil.
I like the pace of your speech. New subscriber. Thanks!
I wanna be an Astronomer !
I demand MOAR of this, NAO! By that I mean, thank you so much for doing this.. for free, you guys are awesome!
I never hated anything more than hearing people saying that I am majoring in Astrology.. One of my mom's friends wanted me to do fortune telling to them and after me saying that i can't she told me that I am bad at my job and I am not going to be able to find a husband lol..

Shoutout to JohnGreen the author of the book "The Fault In Our Stars." "The fault of astrology lies in ourselves, not in our stars." Hahaha
