Messier 66 taken by Hubble Space Telescope on January 28 2021

In this picture, it showcases the star forming regions of the galaxies, which can be seen in red. Star forming regions are vulnerable to disturbances, which can cause the gas in the interstellar medium to collapse into dense clumps of material. These are called protostars.

During the formation of these protostars, gravitational energy is converted into thermal energy. If there is enough thermal energy produced, it is enough to spark nuclear fusion. The star then joins the main sequence.

Due to nature of the star forming regions, it often yields the creation of star clusters, since many stars are being created in close proximity. Large stars especially can emit radiation and produce stellar winds, which pushes the star away from these regions.

target haul!! i went to go grab two notebooks (one for physics and one for math) i normally just use one for the entire year, but this time i’ve already run out of pages in one semester 😳

my computer science teacher says f the trees (his words not mine) and that you should use the paper to do your work and not try to compress it super small. a little extreme, but the point is, don’t be shy to take up space with your notes.

i went for a walk later this evening to decompress and it was so pretty— prepare for more sky pics because i will be going outside more often after today.

- final review physics 2

- ap frq practice

i failed one of the frqs which was pretty disappointing. focusing on the positive, i now know what i need to practice before my final tomorrow!

academia moodboard

nevermind i resolved it

I SWEAR IT WAS WORKING FIVE SECONDS AGO AAA

NGC 2403 taken by John C. Yu on January 30 2024

NGC 2403 is a intermediate spiral galaxy. There are typically two types of spiral galaxies: barred and regular spirals. This galaxy falls between the two, denoted as SAB.

The bar in spiral galaxies forms due to gravitational instability. However, this bar can help with star formation as it funnels material to the center of the galaxy.

Interactions with neighboring galaxies or having greater instability can lead to a greater bar shape in the galaxy. However, dark matter halos also play a big role in having the opposite effect, often preventing the bar from forming. These combined factors lead to the median shape of this galaxy.

Intermediate spiral galaxies can eventually evolve into either regular spiral galaxies or barred spiral galaxies, but we won't be there to see the final form of NGC 2403.

today is a study day (fortunately or regrettably depending on your perspective). this problem set is really cool and i actually like learning about circuits, which i didn’t expect.

- circuits problem set (88 mins)

- circuits quiz (39 mins)

- advanced circuits lecture

i’m REALLY behind in my course and i need to catch up by the time school starts again so i probably have another 4 hrs of work minimum. it’s finally feeling like crunch time lol

random physics comp i probably bombed 😭

classical mechanics is so fundamental but also kind of plain

Sirius A and B taken on 13th December 2005 by Hubble Space Telescope

Sirius A is well known for being the brightest star in the night sky and a part of the constellation Canis Major. However, its binary partner, Sirius B was only discovered in 1862.

Ever since the creation of Newton’s law of universal gravitation, star mechanics became not only descriptive, but also predictive. Sirius A’s path across the night sky was unexpected. It wasn’t a straight line, but rather oscillated across its path. This caused many scientists to suspect that Sirius A had a binary partner.

Sirius B was first observed by Alvan Clark, who was testing a new telescope at the time. This was later on confirmed by other telescopes.

Sirius B is a white dwarf, while Sirius A is a main sequence star, meaning it is much larger and much brighter. 1000x brighter than Sirius B, in fact.

In the photo, Sirius A is in the center (although there are some effects due to the instruments) and Sirius B can be seen in the lower left.

it's okay not to be productive some weeks.

i feel like i got so little done this week. i had to ask for an extension on my physics work and my essay in english. i barely managed to finish the work i needed this week. but that's okay. sometimes its good to have mental breaks.

a good advice i was given was to separate the work from relaxation.

when you are studying, you are studying. less distractions when you are working, and good mental breaks (like going outside or grabbing a snack). but when you are relaxing, you are relaxing. don't let the guilt of not getting stuff done eat at you.

put it in your schedule to relax or something, but sometimes you need breaks. sometimes its difficult for me to get up and do work, and i feel horrible for not being able to do that. but at the same time, its a sign that my mind and my body needs the rest.

go to sleep <3
