17 March (last day of classes)
This quarter has collectively brought out the best and and worst in me. From dealing with heart issues, to dealing with mental issues it hasn’t been a fun time.
I had hopes of getting straight A’s, but ultimately I find myself once again looking just to get through it without failing (read: anything less than a B+). The burnout has been real and very hard to with but, I persevered.
It’s ok just to get through the quarter...
I love y’all ✌🏿
15 March (linear algebra study session)
Today was rough, I was constantly fighting tooth and nail to study, and ultimately didn’t get much done. As much as I love being neurodivergent, it definitely has its drawbacks. However I am going to be headed back to the doctor soon to try and help with my focus.
Just because someone looks alright doesn’t mean that they are conversely, don’t assume that people who don’t look the best are struggling.
I love all of you beautiful creatures

12 March (Calc 3 Pain)
I normally try not to post in color, but today I feel that it’s warranted. I just finished my last lecture with my calc 3 professor and I couldn’t help but be a bit sad.
We all have that teacher whom we don’t expect to make a difference in our lives, but upon getting to know them you come to find that they are a giant breath of fresh air.
With the toxicity of school leeching itself into every orifice, nook, and cranny it was nice having that one class I could count on to be invigorating.
This one is for you Mr. Lewis. I can’t begin to repay you for your teaching service, but the least I can do is show my genuine appreciation for you.
8 March (Calc 3: Test Day)
You know, taking notes by asking questions really has improved my memory retention. I find myself getting the problems correct because I actually understand the process of what is happening not just the system that gets me to where I need to be.
If you haven’t feed yourself or hydrated please do that, every bit helps
Stay up ✌🏿

I SWEAR IT WAS WORKING FIVE SECONDS AGO AAA
i was just looking around the rate my professor for caltech… just for fun…
bro why does this fictional character have more ratings than any real faculty 😭 like most of them just have 1 or 2
should i give in to the hype and watch big bang theory???? 🤨
in my academic weapon era ✍️
physics feels so inaccessible.
like what do you mean the only information on this topic is a power point presentation from ten years ago with only half of the information on it?
or you tell me there's three ways to download the software i need for the calculations, but only one of the ways actually works and you don't even tell me how to do it!!!
never mind the sheer amount of prerequisites. i never struggled with math too much, but i also never took the opportunity to skip a level in math. when i was starting out, you can't do anything without trig. so then i went and learned trig on my own, but then i needed matrices. so i went and i learned matrices and vectors on my own, but now i need calculus. and holy shit is there a lot of stuff within calculus.
half the important papers are hidden behind paywalls and the diagrams are so confusing they take me forever to figure out. maybe i'm just inexperienced, but isn't the whole point of diagrams for the information to be more accessible?????
i might be wrong since i'm young and inexperienced, but it seems as if there's this tone of exclusivity in physics. why is it so hard to find mentors, and when i do, they have such trouble believing in me? i might be young, but i can still understand and help with something. why would you ignore all my emails and just tell me to take the easy way out? i'm in it for the long run.
Dolphin Head Nebula taken by Ben Brown on February 23 2024
The Dolphin Head Nebula, Sh 2-308, is an emission nebula caused by the Wolf-Rayet star EZ Canis Majoris. WR stars have completed fusion of hydrogen and are now fusing heavier elements such as helium and carbon. They have unique emission spectrums for this reason, with no hydrogen emission lines.
The temperature of WR stars is much higher than typical stars, reaching 20,000 K to 210,000 K. WR stars are some of the most luminous stars due to their high temperatures, but most of their output is in the ultraviolet spectrum, meaning we can't see it with the naked eye.
This UV radiation ionizes the gas around it, leading to the emission nebula you can see in the photograph.
The Large Magellanic Cloud taken by Rory Broesder on Februrary 18 2023
The LMC is a satellite galaxy to the Milky Way, set to collide in 2.4 billion years. It is an easily observable object from the southern hemisphere and is the fourth brightest galaxy in the local group. Within this galaxy is the Tarantula Nebula, a very active star forming region.
It was once a barred spiral galaxy before it was disrupted through tidal interactions with the Milky Way galaxy and Small Magellanic Cloud. In fact, there is a bridge of hot gas showing the connection between the LMC and SMC which is also an active star forming region.
The LMC is one of around sixty other satellite galaxies orbiting the Milky Way.
i went to the local library to pick up some books today :) i'm literally so dumb because i was in the wrong row for the nonfiction section (looking for spacefarers) and i did not even stop to question why all the books around me were on the culinary arts.
i heard the master of djinn is a really good book and would be good for people that liked arcane. IF I MAKE IT THROUGH THE BOOK, maybe i'll write a review. hopefully i can because it looks really interesting...
i have a lot of random stuff to do these next two days since i wasn't productive for the first three days of break :(
study for computer science midterm

Flame Nebula taken by Hubble Space Telescope
This nebula is an emission nebula— a star forming region in the Orion constellation. The nebula is filled with young stars; however, dense gas obscures the majority of the cluster.
In this cluster, it contains at least one O-type star that emits light, exciting the gas around it.
O-type stars are huge blue stars that are easily seen from Earth, even from farther distances. They have extremely high surface temperatures, causing them to lose energy at a much faster rate than other stars. These massive stars live for much smaller lifetimes, before resulting in supernova explosions and eventually forming a neutron star or black hole.
f=ma exam…. either i cooked or completely flunked lol
Vela Supernova Remnant taken on February 6 2021 by jeff2011 on Astrobin
The supernova remnant resides within the Vela constellation, having exploded over ten thousand years ago. It is the closes supernova remnant to Earth. Observational data from this remnant provided proof that supernova’s can produce neutron stars.
Supernovas occur at the end of a star’s life. Stars with mass over eight solar masses finish burning the hydrogen in their core and become a red supergiant. Successive fusion then occurs until the core contains iron. Fusion can no longer occur at iron since it is not energetically favorable. Gravity then takes over leading to a supernova explosion— expelling a huge amount of stellar material.
Neutron stars can form as a result of this, as protons and electrons collide to combine into neutrons. The neutron stars are stable by neutron degeneracy pressure. This pressure is caused the Pauli Exclusion principal which prevents neutrons from having the same positions.
The Soul Nebula taken by Kurt Wallberg on Februrary 1 2024
This image depicts The Soul Nebula (IC 1848) on the left and Westhout 5 (IC 1848) on the right. Westhout 5 is part of the bigger Soul Nebula. It’s an emission nebula— consisting of the star forming regions with ionized hydrogen gas and dark nebula. Dark nebulas are when the stellar medium is so dense that the light from objects behind it cannot pass through.
As you can see in the image, there are cavities in the gas. These were carved out by stars due to radiation and stellar winds. There is a theory of triggered star formation, which describes that these cavities compress the gas around it to trigger star formation. Images such as these have been used to help prove this theory, showing that the closer the star is to the cavity, the younger it is.
International Space Station transit of the Moon taken by Quinn Groessl on January 31 2023.
The ISS orbits the Earth at a typical velocity of 28000 km/h (very fast) and at a typical altitude of 400 km. Gravitational forces keep the ISS in constant freefall, but with the forward velocity of the ISS, the overall distance to Earth and velocity stays pretty much the same.
These transits are pretty infrequent. The angle of the moon from the orbital plane can vary over time, and any small changes in the ISS orbit can have major effects on its path. In the sky, they are both fairly small objects, leading to smaller probabilities as well.
An important factor that allows these events to occur is that the ISS is traveling much faster relative to our perspective on Earth compared to the moon. The ISS orbits the Earth around 16 times a day, while the moon takes around a month (27.3 days).
You can see the video of it at this link. It's incredible how precise astronomers have to be with how short of a timespan there is to record this.
AAAAAAHHHH I HAVE A MATH TEST TMRW
Normally, I’m not so stressed, but I missed class this week (I was skipping shame on me 😭) and I have no clue what’s going on… Me and the math teacher are besties because he’s the coach of the golf team, so I’m scared of disappointing him with my bad test scores.
I also had a long lab in chem this week. It’s really sad because we got bad results even though we ran our trial for over and hour lol. I think it’s my lab partner’s fault because he keeps on putting his crusty fingers all over the cuvettes which is messing up the spectrophotometer. Hopefully he actually writes his part so it’s not another repeat of last year.
- Practice midterms for matrices
- Grade practice midterms
- Write lab report
- Debug binary system simulation
- Work on astro research paper
- Work on program applications
- Finish new deal research
- Finish college assessment
- Email people back 😬
Don’t ask me why we have a midterm in January… I have no clue.
Rosette Nebula taken by Suzanne Beers on January 29 2024
The Rosette Nebula is part of the Milky Way Galaxy and is located 5,000 light years away from Earth. The Rosette Nebula is an emission nebula (not to be confused with planetary nebula).
These kinds of nebula are formed around massive, hot stars, whose ultraviolet radiation ionizes the surrounding gas. The excited atoms in the nebula also emit radiation, causing the nebula's glow.
The Rosette Nebula is also home to star forming regions, as observed by the Chandra X-ray Observatory. These are especially concentrated in the bottom of the nebula, although it is difficult to see in this image. Note that this photo uses the Hubble color palette.
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.
Comet C/2022 E3 (ZTF) taken by Auvo Korpi on January 27 2023.
During the formation of the sun, there was a protoplanetary disk (cloud of debris and gas) that orbited around it. The farthest parts of this disk were far from the heat emitted, and cooled down. The cold material clumped with frozen gasses and water, creating icy rocks.
These rocks orbit far away from the sun in huge elliptical orbits, in the Kuiper belt and Oort cloud. At one point, the icy rocks get closer to the sun. The ice is heated and releases dust, known as the comet’s trail.
Comet ZTF was first discovered in March 2022, but came closest to Earth in a long time in January of 2023. At first, the comet was believed to be an asteroid, but when it got closer to the sun, it was observed to have its signature green glow.
The green comes from the diatomic carbon, which is part of the comet’s atmosphere. As it got closer to the sun, the molecules became excited and radiate green light. This is also why the green color doesn’t extend to the tail, instead it is happening in the comet’s nucleus.
I remember going out with my telescope around this time to view the comet. At that point I think it was just above the Taurus constellation, and I had a lot of trouble angling the lens to point that high up.
I don’t remember being able to see the tail, but just with the naked eye, I could see the comet’s light. I can’t believe it’s already been two years since then. Time really flies.
NGC 1316 taken by Hubble Space Telescope on January 26 2021
NGC 1316 is an elliptical galaxy formed by the collisions of multiple galaxies near the constellation Forax in the southern hemisphere. What makes this galaxy unique is the dark lanes of dust visible around the galaxy. These are indicative that they galaxies NGC 1316 was formed by were spiral galaxies.
What helped scientists determine that this galaxy was created due to a "recent" collision where different types of images taken of NGC 1316. Hubble's images helped to reveal huge collisional shells and a small number of globular clusters. Collisional shells are formed from debris of the parent galaxy, which under the effects of gravity and tidal forces. These tails last for a long time, before eventually being reabsorbed into the progenitor (object of origin). Globular clusters are a group of stars bound by gravity.
These two events were indicative of a merger that occurred within the past couple billion years.
“Since it is now past 2 AM, perhaps it’s time to get some sleep and tackle this tomorrow?”
Especially as a student, it seems necessary to sacrifice sleep in order to study for a test more or get that last homework assignment done, and I get it.
It’s a never-ending cycle— stay up late to study, too tired the next day, procrastinate because you’re tired…
I used to sleep around 8 hours, which is generally the norm, when I found that I was still procrastinating and still tired. I thought that this was due to stress and therefore needed to study more to reduce my stress about upcoming tests. This led to me sleeping 6-7 hours instead.
These past couple of weeks, I’ve decided to listen to my body a lot more, often sleeping 9-10 hours.
I’ve become more productive: being able to work towards my goals without losing out on my health, being more energized, and also having more free time.
It seems counterintuitive, right? Sleeping three hours more should reduce how much I get done in a day, but no. I realized I spend a lot of time while I study being off track or doomscrolling on my phone. This actually is a logical result of being tired— not having enough energy to focus on a task and needing the dopamine in a fast release.
So what do I do if I enjoy working late at night? Especially in high school, there’s strict schedules and timings for when you have to be up so that you can be on time. Unless you can get a prep period, you have to wake up at 7:00 am.
I started taking naps as soon as I get home. If I’m not feeling as if I’ll get anything done, I try to get off my phone and just listen to music or daydream as I try to get a little bit of sleep.
If I keep this up, hopefully Copilot will stop criticizing my sleep habits 😁
finally finished my online class!
and now i go back to regular school tomorrow…
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!
