4 billion years of fixing inorganic carbon in the biosphere. Sometimes mistakes O2 for CO2. Not as fast as some enzymes, but very abundant. Here, have some phosphoglycerates about it.

5·1 month agoThe on-the-fly meme-making by the Trekkies is positively inspiring.
Lies, Inc. is another by PKD that will leave your head spinning.
2·2 months agoLooks like Sepia (Peertube), 藍 ‘Ai’ (Misskey), Mastodon, Fox Tan (Pleroma), and Lemmy.

Beautiful. Now I’m feeling the need for an ickplant opossum meme version.
“People are taking the piss out of you every day. They butt into your life, take a cheap shot at you and then disappear. They leer at you from tall buildings and make you feel small. They make flippant comments from buses that imply you’re not sexy enough and that all the fun is happening somewhere else. They are on TV making your girlfriend feel inadequate. They have access to the most sophisticated technology the world has ever seen and they bully you with it. They are The Advertisers and they are laughing at you. You, however, are forbidden to touch them. Trademarks, intellectual property rights and copyright law mean advertisers can say what they like wherever they like with total impunity. Fuck that. Any advert in a public space that gives you no choice whether you see it or not is yours. It’s yours to take, re-arrange and re-use. You can do whatever you like with it. Asking for permission is like asking to keep a rock someone just threw at your head. You owe the companies nothing. Less than nothing, you especially don’t owe them any courtesy. They owe you. They have re-arranged the world to put themselves in front of you. They never asked for your permission, don’t even start asking for theirs.”

Practice.
Taking notes during lecture helped. Not only does it help cement the information in your mind, it is practice writing legibly enough it can be studied later. You could practice this now, before school starts, by watching something like Khan Academy.
If your major sends you to the whiteboard often, that will help a lot, too. You will naturally improve as you do it out of necessity. Practice on the board until you can write a straight line of consistent text that doesn’t droop or curve down as it goes along.
I second the suggestion for calligraphy in a script you like.
Perhaps practice by trying to quickly write down song lyrics as you listen? I think that’s when I first started to improve.
Pay attention to your classmates who can take good notes quickly. I made a friend who found my writing to be glacially slow, so I watched how they wrote to learn some tricks.
Sorry if some of these won’t help until you’re in, but don’t worry about it too much. I’m sure your handwriting will be markedly improved by the end of even the first year.
p.s.
Write letters or postcards to friends.
Try to fit your favorite quotes on a notecard.
Love it. One example that springs to mind is calling out the NCAA.
“‘Student Ath-uh-letes’? Haha, that is brilliant, sir.”
4 laws passed in 3 states over the last 2 years with 1 million dollars.
Clever and impressive. Will YT brush this off and move on or double down and wade into it? Would you want to pick a fight with clever, eloquent nerds who seem to enjoy battling dragons, or EEE while quietly going about other business?
What if the shells were on something like a joystick, such that left-right could be one scale and up-down could be another?
Or maybe sliders in the grooves of the shell?
I love your project and hope it comes to fruition. Best of luck.

I could also be wrong, but I believe SDS has less ‘affinity’ for protons than acetic acid (which is part of the reason why detergents work so well). You’d need sulfuric acid, or something stronger, and removal from solution of its buddy ion sodium. Then I think you could protonate dodecyl sulfate.
Now acetic acid and soaps…yeah, far more likely to generate scum. The polar head is a weaker acid.
The importance of soap to human civilization is documented by history, but some problems associated with its use have been recognized. One of these is caused by the weak acidity (pKa ca. 4.9) of the fatty acids. Solutions of alkali metal soaps are slightly alkaline (pH 8 to 9) due to hydrolysis. If the pH of a soap solution is lowered by acidic contaminants, insoluble fatty acids precipitate and form a scum. A second problem is caused by the presence of calcium and magnesium salts in the water supply (hard water). These divalent cations cause aggregation of the micelles, which then deposit as a dirty scum.
These problems have been alleviated by the development of synthetic amphiphiles called detergents (or syndets). By using a much stronger acid for the polar head group, water solutions of the amphiphile are less sensitive to pH changes. Also the sulfonate functions used for virtually all anionic detergents confer greater solubility on micelles incorporating the alkaline earth cations found in hard water.
