#computational astronomy

[reionized]

are there any books/yt tutorials that helped you learn how to do data processing w python? I really want to learn this summer

FOR SURE!!!! THIS python for astronomy course by freecodecamp is excellent and i have been looking for something like it for AGES!!! https://www.youtube.com/watch?v=H9KefzbryEw&ab_channel=freeCodeCamp.org the same people behind the bootcamp also have a bunch of machine learning projects relevant to space that i am hoping to go through, you can find them here: https://www.youtube.com/@Spartificial/playlists if any of you studyblr folks know any other resources for data processing for space, or just data processing in general, please add on <33

Eviction in the most comical way.

For the past two weeks eye have been trying to crowdfund for a new pair of strong prescription glasses. Because mine are broken.

CA: $HushEmu

PP: emuslayter@gmail.com

Goal: $1275

In that interval I was fired due to “job abandonment” for calling off of work, because I cannot legally drive nor can I see. Now I am facing possible eviction with a very aggressive and hostile landlord.

Proof

THEY tried to evict me despite paying. Just because it didn’t “reflect” on their system on time.

Proof of my broken glasses

I’m still trying to raise $275 for my prescription glasses while trying to raise rent because I am now unemployed.

I am asking to stay housed! :/

If you can’t help financially please advocate for me.

• c+p on my behalf on various platforms

• If you mutuals with large following ask if they can share.

pls help. I’m just a girl.

The top speedrunning discourse for 2024 will revolve around whether deliberately arranging your world record attempts to coincide with predicted peaks in solar flare activity in the hope of performing otherwise-irreproducible skips due to the resulting radiation randomly flipping bits in memory should be considered RTA legal.

Science Major: Man, I sure wish I had time to enjoy college but I have so much studying and homework to do. At least I'll get an easy high paying job after, right?

Physicist: I think I have a pretty good work life balance (does not, actually) and I think my grad students should have the same work life balance (which is not having that)

Astronomer: I work *about 40 hour weeks, but sometimes there are hours are in the middle of the night 'cause, y'know, stars. But who needs a consistent sleep schedule, really? Not me. I got Redbull.

Geologist: Sometimes I get to spend 15 hours a day wandering through the desert in severe weather conditions looking for cool rocks! also I have to like survey the land or whatever so I can get money

Chemist: Oh, you know, my PI only lets me see my family at night for dinner, then I have to come back and sleep in the lab, but overall I’d say I’m not too stressed.

Physician: Well, I had to work really hard, so why shouldn't everyone else have to work even harder? I'm sure the patients could only benefit from everyone being sleep deprived.

Biologist: I work so much I don’t even remember the last time I wasn’t working.

Science Major: huh?

Biologist: I MUST OBSERVE THE CRAB AT ALL TIMES. I OBSERVE THE CRAB EVEN AS WE SPEAK. IF I DO NOT PUBLISH 60 PAPERS ON CRAB BEHAVIOR BY NEXT YEAR MY COLLEAGUES WILL SENSE MY WEAKNESS AND DEVOUR ME ALIVE, LIKE A PACK OF STARVING CRABS

Computer Scientist: Um… I work from home for at most 8 hours a day then play video games

Biologist: *licks lips*

Computer Scientist (Game Dev): I would murder you if I wasn't so... oh there I go- *passes out from exhaustion (hasn't slept or touched grass in five years)*

just found a whole bunch of mick interviews randomly…think this is the most he’s talked throughout the 80’s so i think we should consider ourselves lucky rn.

On god, this semester is my academic comeback. manifesting good study habits and strong self-discipline.

I got my cumulative due dates spreadsheet all set up before classes officially start in the morning, and I got my new desk all decorated and tidy so I feel motivated to study. I'm feelin really optimistic!!

Courses I'm taking this semester:

Elements of Astrophysics (finally!!!)

Analytical Mechanics

Methods of Experimental Physics

Object-oriented programming

Philosophy of Science

Why should you care about quantum computers?

Post #5 on Physics and Astronomy, 23/09/23

Welcome back. It’s been a while. 

First, let’s backtrack. What even are quantum computers?

Today’s computers are run on bits. These are the smallest increment of data on a computer, and are run in binary–they can be in the state of either 0 or 1. This essentially corresponds to two values: off and on. 

This, therefore, means that information can only remain in one, definite state. 

So, what makes quantum computers so different?

A quantum computer is run on qubits (short for quantum bits). Qubits, instead of a single state, can remain in an arbitrary superposition of states (meaning it’s not in any specific state until it’s measured). Qubits, on their own, aren’t particularly useful. But it performs one, very useful, function: it can store a combination of all possible states of the qubit into one area. This means that complex problems can be represented differently in qubits compared to bits. 

Quantum computers aren’t fully developed and at their full capacity quite yet. So far, there’s nothing a quantum computer can do that a regular supercomputer cannot. However, this opens an opportunity for some wonderful new things to happen. 

One of these things can include the cracking of passwords. 

Today’s encryption works by using “trapdoor” functions, which means that data is easy to compute in the forward direction, but extremely difficult to crack in the reverse without special keys. Keywords, ‘extremely difficult’; it is not impossible. However, this is not a massive concern: encryption works on the basis that it would simply take too long to crack.

To give you a tangible example, 100,003 and 131,071 are relatively easy to multiply together, giving you the answer 13,107,493,213. How easy, however, would it be to determine a prime factor pair of this number? It would take a computer a long time to figure this out, since it runs on bits, which can only show one definite state of data.

With quantum computers, it’s different. As aforementioned, qubits can remain in a superposition of states; somewhere in there, the desired answer lies. It’s just a matter of obtaining the resources to make this happen. 

Don’t worry, though. Ordinary people aren’t at any risk quite yet.

why am i actually slaying in computer science this semester

[ad-astra-per-aspera-1389]

The difference between Big Sciences and Little Sciences is so funny to me. I'm taking chemistry and physics at the same time, and I'm an astronomy major, and so far it's been:

biology, chemistry, computer science, etc. : if you're even 0.00001 off from the CORRECT answer then it's WRONG

physics and astronomy: hmm...yeah that looks like enough 0s on the end. you've got enough numbers. that's close enough, who gives a shit
