Star Trails taken by Rob on February 24 2024
Star trails are photographs taken over long exposures, where the rotation of the Earth causes the stars to appear as arcs in the sky instead of points. The Earth rotates around its axis every 23 hours and 56 minutes.
Typically, star trails are focused on Polaris in the northern hemisphere, but I found this photo unique because it opted for a different composition. It also really highlights how dense the sky is with stars.
It begs the question, why isn't the sky infinitely bright with infinite stars? This is actually the observation that helped cosmologists find theories for the age of the universe. For a young universe, not enough time has passed for the light from incredibly distant stars to reach us, leading to the dark sky we see when we look up at night.
homemade strawb matchas & cozy nights studying ššµ
Pretty winter sunset but Iām stuck inside š Just cleaned my room though so I donāt mind that much.
3rd picture is my deskā should I put something on the wall? I donāt want to drill anything in.
Today was pretty frustrating for a variety of reasons, so I didnāt think I would get much done today but then I hopped on to Tumblr and saw a bunch of peopleās study posts so I guess Iām trying this again.
- Study for math test
- Work on research program applications
- Upload a new software onto my computer
Good luck š
there's nothing more satisfying than the program finally working!! i went through multiple breaks of despair only for the stupidest line in the code to be the issue
I did it. I fucking did it. Itās over!!!!
Math exam day stats:
Cry count: only 3!
Headache: 3/10 - pretty good, really not a lot
Moodswings: 10/10 - the first exam was awful the second one alright + confused crying laughing
Tired: 9/10 Iām exhausted
- and only like 18 weeks until I can do all that again and have the pleasure of taking my FINAL exam (Abitur) šš
But until then⦠life is good again
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 supernovaās can produce neutron stars.
Supernovas occur at the end of a starās 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 explosionā 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.
last week this actually worked a little bit, so i'm going to continue doing this. unfortunately, i didn't finish my research paper on immigration by the due date, so i got an extension to this wednesday.
FINISH immigration research paper
submit to photography competition
study for lab quiz :)
gas law and graham's law problem sets
thermodynamics problem set
physics quiz
thermodynamics frq
revise mini-essay
finish enigma machine simulation
probability problem sets
early morning study session! iāve been at it for two hours and iāve only gotten through 7 physics problems but thatās the fun part š
pretty sure i got one wrong bc one of my solutions is 1.3 x 10^65 hydrogen atomsā¦.
I cannot stress the importance of paying attention in language classes in high school. Maybe the reason why your English teacher taught you about unreliable narrators is because a lot of the media around you is written by unreliable narrators posing as reliable. Maybe they gave you assignments on interpreting texts so you could draw your own conclusions about news articles. Some of you clearly thought English classes were useless in high school and now are unable to engage critically with media.
āSince it is now past 2 AM, perhaps itās time to get some sleep and tackle this tomorrow?ā
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.
Itās a never-ending cycleā stay up late to study, too tired the next day, procrastinate because youāre tiredā¦
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, Iāve decided to listen to my body a lot more, often sleeping 9-10 hours.
Iāve 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 tiredā 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, thereās 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 Iām not feeling as if Iāll 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 š
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
calculus unit 4 problem sets
magnetostatics FRQ
read literature for research project
update astrophysics notes
