Introduction to Astronomy

[@celticfreemason9721]

Thank you so much Professor Dave. I'm a 49 year old maintenance technician and am interested in studying to get a BA in mechanical engineering. I use your physics and math courses from time to time as a way to keep my mind fresh and pass time in an educational way. Recently my 14 year old son has showed an interest in science, particularly astronomy. Long story short, I turned him on to your channel and he is now a well-spring of knowledge. Keep up the good work Dave.

[@sarasij1477]

This is very wholesome. Wish you get that degree, sir!

[@unknownbeing8222]

i’m 14 as well, and i cant thank professor dave enough!

if these videos were my teacher during my school years, i probably wouldn't have had to be in special ed learning disability classes from k to 12., I have leaning disability and school was beyond frustrating and upsetting at times. only if i had these videos before i left in grade 12, 2008

[@Strype13]

Damnit. This series isn't receiving nearly enough attention. Dave has put together one of the most excellent astronomy series' ever made (I've seen A LOT!) and hardly anybody is watching it. This saddens me deeply. Honestly, Dave's knack for making complex subject matter incredibly easy to grasp & understand... I'd love to see some of his work make it into classrooms. If it were up to me, his entire channel would be required viewing. We'd have a lot fewer "flat-earther" buffoons running around, for one.

[@geetarani2875]

sir it seems u r super all rounder .. teaching everything .. physics , maths , biology, chemistry , now astronomy.. great

[@SpaceAnomaly09]

He explains in many videos that he gets professionals in that subject to go over his content and acknowledges that he doesn’t know everything, thats what sets him apart from other teaching channels. In real life he was a chemist.

I would suggest you find out what astronomy text they use at your local college,and pick up a copy of it.Or do what I did,and sign up for astronomy 101.I did it because I was interested in astronomy,and because we got to play with the college’s 14”Celestron on a German equatorial mount with a clock drive.It was that telescope that spurred me to get my ownCelestron SuperC8+,whenHalley’s comet appeared in the 1980s

This is why Dave is so good " how can we be so arrogant as to attempt to know them". He's coming from a perspective of the unknowing. Dave understands most of us weren't paying attention during high school cause (unfortunately) most teachers are bad. Bless you, Dave. I know you make money from this but you could make so much more if you just debunked idiots constantly. Thank you for providing education the way you do. You're a man of the people, my dude.

[@kaxtorplose]

I watched this video not because I didn't or don't already understand a lot about astronomy, as a lay person, but because I love hearing these descriptions from a lot of different sources. When I was a kid, the only thing I had was Carl Sagan's book, Cosmos. That's what kicked off my interest. And now, so much more is available. Understanding is at the tips of our fingers, with this enormous thing called the internet. So, I'll watch all of these videos. There's so much that I don't understand or which is hard for me to understand, especially the math of everything. I wish I understood the language of math, but it's always been hard for me. Almost impossible seemingly. I know that understanding math is a talent, and although I have a lot of talent in other areas, I don't have talent in math. Basic algebra is about as far as my understanding goes. But I'm always looking and trying to understand, even math. Trigonometry and calculus, algebra - and once I understand all the math, I will invent: Hypercalculus! And then the internet will break. Sorry about that. Look forward to it though!

It's probably impossible for us to truly understand the deep connection people had to the mysteries of the sky in the past, before the internet, before television, before we had harnessed electricity to illuminate the darkness. It encompassed their worldview, inspired myths, gave rhythm and regularity to their lives, and allowed them to navigate the world.

[@Jazzes.official]

(Correct me if I am wrong.) Earth is in the goldilocks zone, and it might be one of the many possible reasons why there is life on earth. Earth's SOLAR orbit was in the goldilocks zone, which the goldilocks zone is the distance from the sun. The distance the earth, well orbits from the sun, is just perfect enough to form water. It wouldn't be too cold for the water to freeze, nor too hot to evaporate the water. As well as having-- well, non-poisonous oxygen for us to live in. Thus, forming life. Although there are many articles/reports of living things, organisms, in other planets and moons that may not have edible oxygen. There are also reports of water in other planets and moons, such as Mars, the 4th planet from the sun, and Titan, which is one of Saturn's 100+ moons. Although there are more examples. An AU is an astronomical unit! Which is known to be how far the planet is from the sun, some examples is Venus: 0.7 AU, which totals to 107.72 million km! 1 AU totals to ~149,600,000 million km. And Earth is 147.12 million km, which means Earth is 1 AU away from the sun. And, the AU of the goldilocks zone is between 0.95-1.67 AU, so it means Earth fits in the goldilocks zone perfectly. Thus also becoming the main reason that Earth was able to form life.

[@tom2443]

I have a question I'd very much like an answer to, like most things I'm sure there is a simple explanation I'm unaware of : I know about conservation of momentum, this is somewhat related. The earth is in orbit around the sun traveling at something like 60 or 70 thousand miles an hour through space... If we launch a rocket or a satellite or whatever into space, once it leaves Earth's atmosphere wouldn't the Earth be speeding away and have to constantly catch up?

[@tom2443]

I think I've figured it out with some googling ... It's about the Earth's atmosphere, it's gravity etc. I'm guessing that the farther away an object is from Earth the less of this effect, and wouldn't be able to keep up with the Earth's speed.

[@rxmy6690]

I've been trying to decide whether I should pick astronomy or astrophysics. I really like space and I have this drive where I just wanna know everything I can about everything we don't know. We know so little about space, and I hate it, and I wanna learn everything about it I possibly can in my lifetime. What do you think I should pick? For a bit of background I'm pretty smart I would say and I do great in school. Like, on average, I usually finish the year with 97-98 or higher in everything, sometimes almost all 100s, except art. I hate art. I really fvcking hate art. I'm also above grade level in multiple subjects, like in math im 1 or 2 grades above, and in ELA, im 3 grades above. (These are based on test scores that my teachers showed and told me btw). So, what do you think is better, or what I should pick?
