so i know it's already pretty much half way through august but i was on holiday for the first week and have been having a bit of a weird week this week, so i didn't get round to planning until today.
i'm getting kinda bad at picking themes for my planner, so i decided to try something new and get some stickers! i really love how this page turned out, and it's much quicker to make spreads without having to draw things.

Hubble's law is considered the first observational basis for the expansion of the universe, and today it serves as one of the pieces of evidence most often cited in support of the Big Bang model; v = HₒD where v - recessional velocity Hₒ - Hubble's constant D - Proper distance Happy 132nd birthday to the the father of extragalactic astronomy and observational cosmology, Lawyer and Astronomer, Edwin Hubble who was born on this day, 20th November 1889 in Marshfield, Missouri, United States.

11 November 2021 // my sleeping schedule is very messed up atm but i'm trying my best regardless. woke up at noon, got coffee with a friend and then studied at the library from 20.00-midnight.
this library looks so beautifulllll

hi!! your blog is lovely!! my questions are- what does a typical career path in astrophysics look like? a lot of colleges don't offer astrophysics at that level, so what degrees/courses in physics should one consider so that they can study astrophysics in their masters? which programming languages should i learn now as a high schooler so that i can have a smooth transition in college? how do i know if astrophysics is definitely the path for me, considering i'm not a huge fan of high school physics but i love learning about space and am quite fascinated by the field? i'm sorry if they're too many, have a great day!!
tiredphysicist Answer:
First, thank you so much, this made me so happy !
I wouldn't say there is a "typical" career path because any physics course is quite a flexible degree and comes with a range of jobs you can be qualified for. Perhaps a lecturer, researcher for an institution or a data analyst (not necessarily cosmological data, data analysis can be in business too). I would try to keep an open mind when it comes to career choices tbh.
As for prerequisite courses for a Masters in Astrophysics, I would surely say that you will need a Bachelors in Physics or Maths. Perhaps engineering? I would say any Bachelors degree that offers a strong foundation in Physics and Maths would suffice and that should include electromagnetism, quantum mechanics and calculus at the university-level.
It helps to know python well in terms of programming languages. I think that's the one a lot of people start with. It's also quite widely used to analyse experimental data.
As I always say, astrophysics is physics ! So I guess it would be helpful if you liked physics. And honestly it will be so rewarding if you have a strong foundation in high school physics so don't frown upon it just yet !! If astrophysics is truly where your passion lies then go for it. As long as you're willing to give physics a shot and try your best to do well in physics and math then it shouldn't be an issue ! As a school student, I loved physics but I wasn't really the sharpest tool in the box and I suffered greatly to cope with the maths and physics involved in astrophysics. I was under the misapprehension that I would use telescopes and learn all about supernovae or how mysterious blackholes are. While this is true to a small extent, the facts you learn about space are not so much in "words and sentences" as much as they are in the form of rigorous mathematical derivations and proofs. So I guess you would have to see if this is something you'd enjoy.
Hope this helped a bit and have a nice day !!

had to dig out my old particle physics notebook and brush up as i slog through papers from the lab i want to work in this summer…
meanwhile, the yarn *pakidge* arrived and i have launched in— it will someday be a throw blanket for my aunt's upcoming birthday.

Hey everyone (for those who care or just happen to see this)
I've been suffering from depression for several years and realized that being at University made it harder. It was also really tough to just function overall, my grades dropped drastically and I felt I should take some time off to focus on my mental health before I try to finish my degree
It's been almost 2 years since I made that decision and I'm better but not enough… at this point I'm lost in life and not even sure if I still want to continue with my Physics degree. I hate quitting and it feels like I am if I don't… but I really don't know what I want in life
Long story short, I'm sorry I've been MIA but I'm lost and floating through life right now so I'll still be distant and hardly here.
I don't enjoy school and I also lack the focus and drive I'd need for online self-education… so there's also that
If you read all this, thank you ❤ Hopefully you'll still be around when I'm back… if I ever find my way back…

Heloo Tumblrs!
So exam season is starting soon, and everyone is studying (hopefully). Here are some tips that were shared to me by my friends, teachers, and my mom.
These are gonna help y'all a lot. Here goes.
Here's everyone's favorite: *drum roll* treats. Treat yourself. Give yourself food, or some reading time, or even some Tumblr time. Basically whatever you do in your free time. Except you don't do this in your free time. You do this after you finish a topic or a concept. You treat yourself. I study for 45 minutes, and take a 15 minute break. That shit works like medicine.
Next one: don't procrastinate. I love procrastinating. You love procrastinating. Everyone loves procrastinating. *insert tiktok video here* don't do it bitch. As much as you want to do it, you'll never reach your goal if you procrastinate. And you need to reach your goal. So to stop procrastinating, use a bujo/studyjo (bullet journal/ study journal). Plan stuff out. Sooner or later, you'll start feeling guilty for not completing those tasks. Be your own creepy duolingo bird.
Don't use your goddamn phone. Phones are distracting. Very distracting. If you have enough self-control, use your phone during that 15 minute break of yours. But don't keep it beside you in those other 45 minutes. Use a wallpaper which says go study bitch or keep your phone down. If y'all are Gilmore Girls fans, just use Rory as your motivation. Here's my wallpaper:
Now we'll move on to guilt. Guilt is a main factor that motivates most people. I feel guilty for not studying when I read all those motivation quotes on Pinterest. Find your guilt factor. Push yourself towards success.
Feeling sleepy while studying? Stop studying. You might say that this is shit advice, but listen to me, it isn't. Put on a timer for 20 minutes, and take a power nap. Sleep the hell outta yourself in those 20 minutes. You'll be refreshed when you wake up. And if you don't trust yourself to wake up or if you think that sleeping isn't a good idea, hydrate. Hydrate, hydrate hydrate. I'm ready to type this a million times till y'all get it. HYDRATE.
Bonus: For those who have their exams in two/three months. Exams are in May? You don't wanna study? Great. Just don't have a zero day. Read a few pages of your textbook. Or reread your notes. Solve a few sums. Solve one sum. Why one you ask? Because one isn't zero.
I hope these help! Toodles.

Planetary nebula
A planetary nebula, abbreviated as PN or plural PNe, is a kind of emission nebula consisting of an expanding, glowing shell of ionized gas ejected from red giant stars late in their lives. The word "nebula" is Latin for mist or cloud, and the term "planetary nebula" is a misnomer that originated in the 1780s with astronomer William Herschel because, when viewed through his telescope, these objects resemble the rounded shapes of planets. Herschel's name for these objects was popularly adopted and has not been changed. They are a relatively short-lived phenomenon, lasting a few tens of thousands of years, compared to a typical stellar lifetime of several billion years.
Most planetary nebulae form at the end of the star's life, during the red giant phase, when the outer layers of the star are expelled by strong stellar winds. After most of the red giant's atmosphere is dissipated, the ultraviolet radiation of the hot luminous core, called a planetary nebula nucleus (PNN), ionizes the ejected material. Absorbed ultraviolet light energises the shell of nebulous gas around the central star, causing it to appear as a brightly coloured planetary nebula.
Planetary nebulae likely play a crucial role in the chemical evolution of the Milky Way by expelling elements to the interstellar medium from stars where those elements were created. Planetary nebulae are observed in more distant galaxies, yielding useful information about their chemical abundances.
Stars greater than 8 solar masses (M⊙) will likely end their lives in dramatic supernovae explosions, while planetary nebulae seemingly only occur at the end of the lives of intermediate and low mass stars between 0.8 M⊙ to 8.0 M⊙.

wonders-of-the-cosmos:
Herbig–Haro (HH) objects are small patches of nebulosity associated with newly born stars, and are formed when narrow jets of partially ionized gas ejected by those stars collide with nearby clouds of gas and dust at speeds of several hundred kilometres per second. Herbig–Haro objects are ubiquitous in star-forming regions, and several are often seen around a single star, aligned with its rotational axis.
HH objects are transient phenomena that last less than a few thousand years. They can evolve visibly over quite short astronomical timescales as they move rapidly away from their parent star into the gas clouds of interstellar space (the interstellar medium or ISM). Hubble Space Telescope observations have revealed the complex evolution of HH objects over the period of a few years, as parts of the nebula fade while others brighten as they collide with clumpy material of the interstellar medium.
