International Space Station Transit Of The Moon Taken By Quinn Groessl On January 31 2023.

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.

i made this post a while ago and omg its even worse than i thought. i'm working on some electrostatics problem sets rn. how are you going to have v for velocity, V for electric potential, V for the volts unit, V for volume, U for potential energy, u for energy density, v (or i guess nu) for neutrinos, v for frequency???? they all look the same...

don't even get me started on k

why are there so many variables in physics? it’s like reading a whole new language and i’m dying here 😭

.. > 12dopmas challenge, Day 2

I made notes for one of my last year's math units (im repeating the exam) and I started making notes for this year's work

/

/

Did 2 pistol squats on each leg (seems very little but they're actually very difficult! or are for me anyway)

I finished a digital drawing I started a while back. I think it's just alright, no strong feelings about it but im glad I got it done

I forgot about the questions again but I will catch up on them!

130 days clean

Day 0

chemistry has been kicking my butt lately. so i’m staying after school to study. yay 😀

on the bright side, i somehow managed to secure more than 100% in my comp sci class with a huge fail rate… not really going to question it in case it was a mistake tho. take the wins when they arise

Messy notes are so nice to make! The diagrams just hit different. Reading back through it is a pain though.

I love aesthetic notes but its not realistic for a lot of people. If it is for you, that is amazing! But this is an appreciation post for messy/near-unreadable notes, notes that still work as notes and help you get good marks but don't look pretty "like they should"

#1. NO MORE GUILT

Ever find yourself crashing out after a long day at school, sitting on your bed watching Netflix, and getting nothing done? It sounds horrible when I put it that way. Bed rotting, doom scrolling, whatever it is, it’s never a fun thing.

Here’s the thing though— it doesn’t have to feel that way.

There are two states that we can consider you to be in. Focus and Relaxation. The situation I described above is caught in between these two states. You want to be in a focus state, but you’re overwhelmed and stuck in your relaxation state. The opposite is also true. You try to get work done but catch yourself distracted, on your phone, instead. You are in a focus state, but you want to be in a relaxation state.

The number one change you can do to help your mental health is to choose a side.

When you are in your focus state, commit. You put your best effort in and keep your mind engaged in what you are working on. No distractions. This is going to help you get so much more work done in a shorter period of time. As you practice this, you are going to realize that when you are in your focus state, distractions are less enticing and you will be able to maintain it for longer.

Disclaimer: if you have to tell yourself to “lock in” you aren’t doing it right. Forcing yourself into a focus state is never going to work, it's just going to lead to that same, tiring, useless feeling.

To actually decompress and feel happier, you can’t have second thoughts in your relaxation. Set a timer if you have to, but you need to let yourself enjoy whatever you are doing. Imagine this: after a long hard day, you treat yourself by getting some popcorn, bundle yourself up in blankets, dim the lights, and get to watch the movie that’s been on your bucket list for the past week. So much better than what we started with, right? The cycle of guilt relaxation starts with wanting to decompress but feeling guilty the whole time. You don’t rest and aren’t happy because all you’ve been thinking about is “I have to get work done.” Instead, you get more tired, and you need to continue laying around or scrolling on your phone.

You don’t have to change your entire routine— just be more mindful about which state you are in and how you can take advantage of that.
