UnAesthetic Studyblr

i’m finishing my degree this year so i thought i’d share some of the things i’ve painstakingly and slowly learnt over 4 years of studying physics at university. i started out by failing foundation mathematics, then all of my first year physics modules, but despite never having to go back and pass these basics (thanks covid) i’m somehow doing well in third year. so, here is my wisdom:

[disclaimer: of course, the way i study will definitely not work for everyone so only take the parts that resonate. this is not the healthiest way to study, but rather how i personally am getting through such a hardcore course with limited physical and mental energy.]

past exam papers. look for patterns and types of questions that are asked often, and focus on understanding those. if you’re lucky this could be all you need to get a great grade.

don’t worry about understanding whats going on in lectures. sitting in lectures and not knowing what the hell was going on used to stress me out to the point that i stopped going, but i found that actually, just turning up and calmly copying down the maths and notes without understanding them really helped me piece it all together later, on when studying on my own.

similarly, i find copying out the notes without trying too hard to understand them to be very helpful. it is very time consuming, but worth it when no information will sink in by just reading through the notes. even if you still don’t understand it all after writing it out, you now know what information is covered, where to find it, and you hopefully have it in a clearer, more interesting to look at format to help you later.

learn on your own terms. don’t listen to what any other people say about how you should study. you know what works for you. its always stressed here how important it is to go to lectures and tutorials, but i know that for me, a lot of the time my energy is better used by staying at home and teaching myself in a calm, comfortable, low pressure environment.

hyper-organisation. have as many planners as it takes to keep a grasp on time and schedules and deadlines. i have a bullet journal, a pre-made planner to scribble in, a planner and tables of dates and deadlines on notion, as well as sticky notes above my desk reminding me of the main things i should be working on at the moment. keep it all in front of you where you can see it, or make it easy to access. 

create a nice environment. this is possibly the most important part. make it so that sitting down to work is enjoyable, and setting up doesn’t take valuable brain power. playlists of background music ready to go, everything you need nearby and organised and easy to access.

ask for adjustments, extensions, ECs. i’m still not good at this, but it can really make all the difference. when you can’t complete something in time or the thought of doing a thing alone makes you feel like dropping out, its always worth asking if something can be done to make it easier for you. (for instance i usually skip presentations and  take the 0 but after asking, i have been allowed to make videos instead and sometimes even just make the powerpoint and write out a script.)

a consistent sleep schedule would be great, but don’t sweat if your class schedule makes it difficult. i work best at night, but lectures mean i have to wake up early in the morning. i have tried going to bed early and while that made waking up and going to classes easier, without my nighttime productivity i got way behind on everything. so instead i let my body do what it wants when it wants, which usually means sleeping less at night along with naps in the day and a lot of catch up sleep at the weekend.

caffeine can be your best friend or worst enemy. use it wisely. (i owe my second year grades to the ginger monster energy flavour)

know when to push and when to rest. sometimes you know its just executive dysfunction stopping you from getting things done, in which case gently push yourself to keep working. even if you don’t manage much, any amount of productivity is good. but on the other hand, if you keep trying and trying and its still not working, thats probably a sign you should stop. if you don’t make time for rest, your body will take it for you. 

on that note, if you really can’t focus, stop to think about whats actually wrong. sit still, relax for a moment and zone in to yourself. is it because you’re hungry? cold? understimulated? do you not have all of the materials you need right in front of you? it could be something as simple as the lighting being off, or things being in the wrong place on your desk. 

break it down. when i’m stuck, most often the problem is that i don’t clearly know what to do next. break tasks down into steps, and then break those down again until you have small tasks you can easily face. baby steps are the way to go. 

something is always better than nothing! you don’t have to put your all into everything. if you’ve got 60% to give on an assignment, thats great. even 40%, 20%. handing in something bad and unfinished is still worth it, and sometimes all you need. 

The human eye only has three types of color sensitive cones, which detect red, blue, and green light. Your brain is making up every other color you perceive.

Let’s have a little fun with that thought. This is the visible spectrum of light.

You will of course note that yellow is on the chart. Yellow has a discreet wavelength, and is therefore a distinct physical color. But we can’t see it.

“Sorry, what the fuck?”

What we call yellow is just what our brain shrugs and spits out when our red and green cones are equally stimulated. We have light receptors that can pick up on the physical spectrum of light we call yellow: that’s why yellow things don’t just look like moving black blocks to us. But your brain has no fucking idea what the color yellow looks like. 

Some animals have eyes that can perceive the color yellow! Goldfish have a yellow cone in their eyes. If they could talk, they could tell us what yellow looks like. But we wouldn’t be able to understand it.

What your brain actually sees of the color spectrum:

We can measure the wavelength of light, so we know that when we see ‘yellow,’ we are seeing light in that 550-ish nanometers range. But we don’t have a cone in our eyes that can pick that up. Your brain just has a very consistent guess about what color that wavelength of light could be. We decided to name that guess ‘yellow.’ We can’t imagine what yellow really looks like any more than a dog can imagine the color red.

Here’s the funny thing: your brain is never perceiving just one photon of light at a time. Something like 2*10⁸ photons per second are hitting your retina under normal conditions. Your brain doesn’t individually process all of them. So it averages them out. It grabs a bunch of photons all coming from the same direction, with the same pattern, and goes, “yeah, that cup is blue, fuck it, next.”

That’s how colors blend in our eyes. So sure, if a photon of light with a wavelength of 550 nanometers bounces into our eyes, we see what we call “yellow.” But if we see two photons at the same time, coming from the same object, one of which is 500 nms and the other of which is 600 nms, your brain will average them out and you will still see yellow even though none of the light you just saw was 550 nms.

So how does magenta factor into this?

Well, as we’ve just established, when your brain sees light from two different slices of the visible light spectrum, it will try to just average them together. Green plus red is yellow, fuck it. If it’s more red than green, we’ll call that ‘orange.’ Literally who gives a shit, we’re trying to forage over here. There are bears out here and it’s so scary.

What happens if you take the average of blue and red light, which we perceive to be magenta? What’s the centerpoint of that line?

Fucking green.

Hey, that’s not gonna work? We live on a planet where EVERYTHING IS GREEN. If something is NOT green, that means it’s either food, or a potential source of danger, and either way your brain wants you to know about it.

So your brain goes, WHOOPS. Okay - this is fine. We already made up yellow, orange, cyan, and violet. We’ll just make up another color. Something that looks really, really different from green. 

And so it made up magenta.

So, physics-wise, is magenta “real?”

No; there’s no single wavelength of light that corresponds to magenta. But you’re rarely seeing only a single wavelength of light anyway. And even when you are, every color other than RGB is a dart thrown on the wall by your meat computer. This is the CIE Chromaticity Diagram:

Explaining this thing is a little more than I want to take on on a Saturday morning, but I’ve included a link above that goes into it a little more. The point is that only the colors that actually touch the ‘outline’ of the shape actually correspond to a specific wavelength of light. All of the other colors are blends of multiple wavelengths. So magenta isn’t special.

Given that color is just a fun trick your brain is playing on you to help you find food and avoid danger, is magenta real?

Yeah, absolutely. Or at least, it’s just as real as most of what we see. It’s what we see when we mix up blue and red. It would be disastrous from a survival standpoint to perceive that color as green, so we don’t. Because it’s not green. Light that’s green has a wavelength of around 510 nm. Stuff that’s magenta bounces back light that is both ~400 and ~700. Your brain knows the difference. So it fills in the gap for you, with the best guess it has, same as it does with your blind spot.
