OKAY THIS ARTICLE IS SO COOL
I'm going to try to explain this in a comprehensible way, because honestly it's wild to wrap your head around even for me, who has a degree in chemistry. But bear with me.
Okay, so. Solids, right? They are rigid enough to hold their shape, but aside from that they are quite variable. Some solids are hard, others are soft, some are brittle or rubbery or malleable. So what determines these qualities? And what creates the rigid structure that makes a solid a solid? Most people would tell you that it depends on the atoms that make up the solid, and the bonds between those atoms. Rubber is flexible because of the polymers it's made of, steel is strong because of the metallic bonds between its atoms. And this applies to all solids. Or so everybody thought.
A paper published in the journal Nature has discovered that biological materials such as wood, fungi, cotton, hair, and anything else that can respond to the humidity in the environment may be composed of a new class of matter dubbed "hydration solids". That's because the rigidity and solidness of the materials doesn't actually come from the atoms and bonds, but from the water molecules hanging out in between.
So basically, try to imagine a hydration solid as a bunch of balloons taped together to form a giant cube, with the actual balloon part representing the atoms and bonds of the material, and the air filling the balloons as the water in the pores of the solid. What makes this "solid" cube shaped? It's not because of the rubber at all, but the air inside. If you took out all the air from inside the balloons, the structure wouldn't be able to hold its shape.
Ozger Sahin, one of the paper's authors, said
"When we take a walk in the woods, we think of the trees and plants around us as typical solids. This research shows that we should really think of those trees and plants as towers of water holding sugars and proteins in place. It's really water's world."
And the great thing about this discovery (and one of the reasons to support its validity) is that thinking about hydration solids this way makes the math so so so much easier. Before this, if you wanted to calculate how water interacts with organic matter, you would need advanced computer simulations. Now, there are simple equations that you can do in your head. Being able to calculate a material's properties using basic physics principles is a really big deal, because so far we have only been able to do that with gasses (PV=nRT anyone?). Expanding that to a group that encompasses 50-90% of the biological world around us is huge.

Hey you. You know you should be doing The Thing. I don't want to do The Thing, either. But we can sit down and do it for 2 minutes together. Then we can do it for 5 minutes. Then 10. And so on and so forth until it is done. I'll be coming back to reiterate this.
To whoever needs to hear it: it does not have to be perfect. It does not have to be world altering. It just needs to be done. And I'll sit with you while you do The Thing.
Now go. Stop scrolling. Go work on The Thing. I'll be back to check on you and cheer us both on.

adhd study affirmations + tips to stray from discouragement by a stem student with adhd.
you’re not always going to be consistent. you’re not always going to be motivated. you’re not always going to be efficient. and that is okay.
edit : thank you so much to whoever blazed this post. It means the world to me.
and the fact that you even got this far is an accomplishment in and of itself. In this line of work, people aren’t always the kindest to neurodivergent people especially since our symptoms can often hinder our performance academically.
if you’re good to go after reading the above, I’ve also made a post regarding adhd study tips that I haven’t seen anywhere else. (Part 2 is here!) But, if you’re burned out like me, feel free to keep reading.
honestly, these might serve a bit more as reminders because they’re kinda simple but even I needed this, so, here we go.
do not seek advice from anyone neurotypical unless it genuinely helps you. I cannot tell you the amount of time and tears I could have saved if I just considered the fact that just because popular self-improvement tips or study techniques didn’t work for me, it doesn’t mean I’m stupid or useless. It simply means our brains isn’t motivated by the same things neurotypical ones are, and therefore a lot of popular self-improvement videos or study tips aren’t going to work for you because 90% of the time, they’re not designed to work for neurodivergent people. So if you’d like to seek help in this area, look for tips and videos that ARE for neurodivergent people.
you might experience burnout a lot more than others. again, that is fine. if this doesn’t apply to you, great! Feel free to skip to the next tip/affirmation. If this does apply to you, read this carefully; if you’ve had any sort of streak in studying right now, chances are you know at least a portion of your studies were led purely on interest, curiosity or even novelty, as these are what keep us engaged in our studies. Knowing this, it is natural for you to experience burnout more frequently than others due to the possible hyperfixations that have been forming around your work. If you get burned out, please remember to take a break for a day and make sure it is efficient. Like your studies, your breaks are the key to having efficient study sessions in the future. So please treat yourself, especially if you’ve been working extra hard!
do not admire studious fictional characters unless it genuinely helps you or they too are neurodivergent. I know this technically could have been thrown in with tip number 1 but I felt like this tip alone is so important, because nowadays I see a lot of study tips with the title, ‘how to study like (insert studious fictional character here)’ and when I look at the post it kinda repeats the same few study tips I see all the time like ‘stay organized’ or ‘time block your day’ and I feel like admiring fictional characters who do things that don’t work for you can be damaging for your mental health, because we’re already told by neurotypical people all around us that we’re slow or lazy just because we don’t do things the way they do, and I think idolizing neurotypical people that make us feel bad at the end of the day just further promotes that kind of toxic thinking.
expect that a routine/schedule/technique that has been working for a while now may not continue to work in the future. things will always have to be new for us to be interested or engaged, that being said, if you expect this in the future you won’t be frustrated with yourself because you already had this in mind. It doesn’t mean you’re not smart. It doesn’t mean you’re lazy. It doesn’t mean you’re useless. It just means that you’ve done what you could, and now it’s time to move on to another routine/schedule/technique.
keep doing the things you love alongside work. I find that because our symptoms may cause us to fall behind on our studies, we tend to neglect our other needs as human beings just to make up for the fact that we simply do not learn or pick things up the same way neurotypical people do. Your hobbies and interests need to be part of your day, just as your studies do, even if you may take longer to learn things or remember important concepts in your studies. Neglecting your hobbies or interests can lead to even more frequent burn outs and even a relapse in depression and anxiety, so please take care of yourself and recognize that you need and deserve these things just as much as anyone else.
regularly discover what works for you on your own. here’s the thing; neurodivergent or not, no two brains work the same. Of course it is good to try out advice or tips you find online because they’re backed up by experience, but they’re backed up by that person’s experience with working with their own brain. So naturally, you need to find what works with your brain. Be open to trying everything, even the tips that are discouraged like listening to lyrical music while studying. That was the only way I learnt that this tip actually does help me at times, even when many people have said that it negatively affects your focus.
that’s all I have right now guys, I think I’m experiencing burn out or probably falling back into depression again so more than anything this also served as a reminder for me, but I really hope it also helped you guys nonetheless.
As always, tell me if you guys would like more posts like these and I’ll be happy to make more <33 please take care of yourself guys, and remember that your studies is just one aspect of your life. There are other aspects that need your care and attention too.

How to make plasma in the microwave using a grape (don't)
youtube
For those of you who don't want to watch the whole video (I recommend watching it, if only for the guy's extremely blase attitude to fire and poisonous gas in his microwave, here is just the plasma part:
Tumblr media
And the crazy thing is, even though people have been making videos of this for over 20 years, scientists didn't actually know why it happens until 2019.
Basically, plasma is what happens to matter when it is superheated enough that electrons start to come loose from the atoms they belong to and just create a soup of charged particles. This Science article explains well how this effect is created by a halved grape connected by a thin strip of skin:
"Water-heavy grapes trap the wavelengths of energy microwave ovens emit because the waves are roughly the same size as the diameter of grapes. That energy starts charging up electrolytes inside the fruit, which then flow from one half of the grape to the other—using the strip of skin like an electrical wire and gaining energy as they go. The current quickly burns through the skin, causing the charged electrolytes to try to jump from one half of the grape to the other, supercharging the surrounding air into a bright flare of plasma—the same light-emitting state of matter responsible for the sun's rays and fluorescent lighting."
You can see in these energy diagrams of the microwaved grapes that when the grape halves are moved closer together, alllllll of the energy that is normally distributed throughout the two grape halves condenses down into an extremely small area between them to form a hotspot of radiation. The energy of this area is so great that it can heat the surrounding gas enough to turn it into plasma.

All this to say that this is a super cool quirk of science that you definitely should NOT try at home (the scientists doing the experiment to find out why this happened destroyed 12 different microwaves in the process lol)

I saw a TikTok recently that really changed my view on education and learning. I forget the exact quote but it said something along the lines of “learn in good faith, and the grades will come”
So often I find myself obsessing over getting an A and not taking time to enjoy the fact that I am studying what middle school/high school me dreamed of. My younger self would hear about the things I am accomplishing and would be so excited. So that raises the question, if I picked these classes, why should my desire for a 4.0 outweigh letting myself enjoy the learning process and just doing the best I can? Good grades come to those who like and resonate with the material being taught. Maybe instead of focusing on memorization for some topics, emphasizing and spending time on relating the content and deepening my understanding is better. I've found that my chem lecture is so fascinating and just having the opportunity to learn more about the complexity of the world around us is so cool. While reaction rates can be boring, when thinking about it, catalysts have huge biological impacts in our body's daily functioning. Life simply would not be able to do what it does without these reactions. I am learning about details that relate to the reactions that allow me to have the energy to move. Learning becomes more valuable when you don't focus on the destination( a grade) but think about it as a journey.

sorry we applied an operator to your boyfriend. he's an eigenfunction of that operator so the operator returned his function but he's multiplied by a constant. yeah he has an eigenvalue now
