im so fine right now. im normal, even

#i need to eat dinner but i cant do so because if i do i will cede the study room and theres NO fucking way i'll get work done anywhere else #so i have to wait for my roommates to get here so they can keep the room so i can go get dinner (and also so i dont ahve to write alone)#and aslo i cant take another ibuprofen on an empty stomach adn i am in so much pain rn #my luck has been so fucking ass the past couple of days #nearly fell in the pond and did drop my water bottle in it; scalded my hand while boil washing it; tripped on the way to one of my classes;#slept through astronomy this morning; they didnt have any coffee at the dining hall until after i left; spilled my second cup of coffee all #-over the table in the study room; AND i have a major essay and two homework assignments due tomorrow and an upcoming exam

skipped my beloved astronomy lecture to go through another practice calc exam </3 I am in shambles

#doing pluto so dirty rn #it's okay I already know a fair amount abt the kuiper belt missing one lecture won't tank my grade #but my beloved astronomy lecture </3 #no new space facts today I'm afraid only grinding for my exam #stella rambles #actually unreasonably upset by this #like I was the one who made the decision but a part of me regrets it </3 #because I haven't skipped a single astronomy lecture this quarter #because I love the subject so so so much #but idk I cannot afford to do badly on this calc exam #so like I'm full of regret but also know I gotta keep grinding for this exam </3

Queer Media class ended.

Today was the last day technically.

So that’s a little saddening.

#mun says things #I’ll rest once I finished what I need for German and study for my astronomy exam

My headcanon about you is that you have those glow in the dark star stickers on your ceiling.

Awwwwwww I actually had these when I was younger. My room always had some star patterns somewhere and if it didn’t i would have just painted the walls with acrylic paint hehe ✨

#about ness #thxuuu jay🧡#ask game #maybe i should get those glow in the dark star stickers again #kinda miss them ngl #i just really love the stars #back in school i even had astronomy #but i sucked at the exams because i never studied for it lol

I actually refuse to believe that i did this entirely correctly, and only missed half a point for forgetting that $\pdot_x = - dh/dh$ is negative

#me #college #astronomy #physics #exam #45.5/50 how does that happen

The other day (literally yesterday) in physics I got a question on a binary star system, about redshift and the Doppler effect. Now, I missed the initial lesson on Doppler shift and the Hubble constant etc., but I caught up in my own time, this means I don’t know the intricate details, but being familiar with the wider concept.

In this question I was trying to use the equation

Change in wavelength over wavelength equals speed of observed body over the speed of light

But I hit a snag - the question said “the stars are observed using light that was wavelength 656nm in the laboratory. The observed light from the stars is Doppler shifted.”

I thought that this meant that the light observed in the laboratory from the star was already Doppler shifted, so I did the question accordingly. I found out, however, that I couldn’t find out how much it was Doppler shifted, so after a few minutes I asked my teacher. He said that actually the light wasn’t Doppler shifted. The question meant that they reproduced the light in the laboratory and they found it was 650nm without Doppler shift.

How was I meant to get that from the question????

Anyway that sucked but I carried on. I then found out that I didn’t know what the speed was the stars were moving away from the earth. The equation v=H0d didn’t help as I didn’t know what the distance d from the earth was.

Feeling bewildered I asked again, and he said “it’s a binary star system, just find out the speed of the circular motion” and started explaining that. I said “I know, but that speed would be negligible compared to the speed of it moving away from the earth”

And then he went “oh no they’re not moving away from each other”

??? I though everything moved further away from each other, and it was directly proportional to the distance.

He said “yeah but the stars are in the same galaxy as the earth so they’re orbiting a common point”

I was just supposed to assume that??? Yeah it turns out that they went over this in lesson but I didn’t find out about it in my catch up.

The guy next to me then went “v=H0d” only applies to galaxies

That would’ve been nice to know 😂

Anyway this is why we go through papers, so this doesn’t happen in exams
