Physicists: The Words We Are Using To Define Terms Have Specific Mathematical Definitions, So It’s

Physicists: the words we are using to define terms have specific mathematical definitions, so it’s important to use the correct words to talk about the correct quantity

Also physicists: Hahaha, luminous intensity isn’t an intensity, luminous flux isn’t a flux, and optical power isn’t a power!

How to remain productive with online classes:

A few tips from a broke neuro-divergent academic

Try and wake up early, and go to bed early too. I’m not saying get up at 5 (unless that’s you’re thing) but sleeping into noon is a productivity blackhole. I go for 8 or 8:30, generally, but that’s just what works for me.

Get dressed for the day. I’m not talking like, jeans and a business casual outfit, but a clean pair of sweatpants, fresh underwear, and a new shirt can really put you in the mood for a new morning.

Have a workspace. Whether it be the kitchen table, a desk, a spot on the floor with a lap desk, have a place that’s dedicated to your work. Have items that signify that workspace too, like your book, planner, laptop, lamp, whatever. It can help you get into the zone, being in that space.

Have a morning drink. I choose earl grey tea with honey and cream, but black coffee, herbal tea, lemon water, whatever works for you is awesome, as long as itll wake you up and start your day.

To do lists. To do lists and to do lists and more to do lists. I have three. One is a post it weekly planner deal (3.99 at a local grocery store). it’s a weekly spread already set up, and if you’re anything like me, its really hard to set up a weekly spread. Then I have an app called Ike. I have a daily to do list I write on that app, and then I have four more to-do lists of what I have to for each specific class.

Spread out your assignments. Don’t overwhelm yourself. If you’re professors are like mine, and have the due date for each module as Sunday at midnight. What I do is spread out all my assignments from Monday to Saturday, and I leave Sunday blank, so anything I didn’t do that week, I finish on Sunday. It works for me, it might work for you.

Have a folder for each class, and a notebook for each class. I hate spending money, I’m broke as hell, sono al verde as the Italians say, but a 0.99 cent folder and a 0.25 cent notebook can do wonders for motivating one to fill them up.

Study with a drink. Tea, water, coffee, whatever, but my go to is generally a warm drink. I cannot study if I’m cold, I get tired and groggy, so warm socks, a robe, and a hot drink really keep me going.

Take breaks. Make time for your hobbies, for something fun. Working without stopping absolutely destroys my motivation, and let me tell you, when I feel like that, an episode of Avatar and a snack gets me right back on the wagon.

Do self check ins. Does your back hurt? Are you sad? Stressed? Do you have to pee? Are you hungry? Never put your homework over your health. You won’t be able to get anything done well anyway if you’ve got those blocks.

Most importantly, get enough sleep. I beg of you. Sleep is so important, and it’s the game changer, at least to me. We as students have such an amazing opportunity to get more sleep than we ever have before during the year. Take advantage of that.

You know what. I’m starting a new aesthetic, population me.

Romantic Science, AKA Dark Academia for STEM people.

Thrifting a lab coat and embroidering it with your initials and a little insignia, whose significance is known to you and your lab partner only

Watching The Theory of Everything and The Imitation Game and Hidden Figures and basically every movie about historical scientists and mathematicians you can find

Decorating your desk with old slide rules and vintage lab equipment. Your prize possession is a set of vintage lenses you found at a thrift store

Wanting an articulated human skeleton far, far too much

Getting a set of (brand new, NOT thrifted, be safe ppl) beakers to drink from, and putting them directly onto your stovetop to boil water for tea or coffee, because borosilicate glass can survive anything.

Secretly relating far too much to Henry Jekyll and Victor Frankenstein, because you too want to do a gay little science experiment that challenges god.

Thunderstorms and late nights in the lab, the light of the Bunsen burner glistening off of your flasks and scribbled chalkboard equations

Papering your walls with vintage scientific diagrams; even if you know that our understanding of the world has evolved since they were made, looking back at scientific history is amazing

Writing code late at night and feeling, in some metaphysical way, as though Ada Lovelace herself is with you in spirit

Being far, FAR too obsessed with the concept of emergent ai sentience and how it has the potential to be Frankenstein irl

Looking through a telescope on clear nights, whispering the names of the constellations and stars, painting a star chart on your ceiling in a burst of creative inspiration

Collecting and mounting samples from everywhere you can think of to pore over in an antique microscope

Bringing a field journal wherever you go, learning how to draw and label botanical samples, preserving plants and flowers for study later

Dreaming of what undiscovered mysteries lie in the deepest depths of the sea, feeling the thrill of discovery whenever you learn about a new species and one day hoping to discover one yourself

Just. Romanticise STEM.

Listen to your elders

So last week I posted abut the importance of downloading your fic. And then three days later AO3 went down for 24 hours. No one was more weirded out by this than I was. But while y’all were acting like the library at Alexandria was on fire I was reading my download fic and editing chapter eight of Buck, Rogers, and the 21st Century. And also thinking about what I could do to be helpful when the crisis was actually over.

So first off, I’m going to repeat that if you’re going to bookmark a fic, you really need to also download the fic and back it up in a safe place. I just do it automatically now and it’s a good habit to get into.

But let’s talk about some other scenarios. Last October I lost power for over a week after hurricane Ian. Apart from not having internet or A/C I did find plenty to do, I collect books so I had plenty to read, but maybe, unlike me, your favorite comfort reads aren’t sitting on a bookshelf. So let’s do something about that, shall we?

In olden times many long years ago around 1995 we printed off a lot of fic. It was mostly SOP to print a fic you planned to reread and stick it in a three ring binder. And that’s totally valid today too, but you can also make a very nice paperback with a minimum amount of skill and materials.

Let’s start with the download; Go to Ao3 and select your fic, we’ll be working with one of mine. This method works best with one shots, long fic tends to need a more complicated approach. Get yourself an HTML download

Listen To Your Elders

Open up the HTML download and select all then copy paste into any word processor. Set the page to landscape and two columns, then change the font to something you find easy to read, this is your book, no judgement. This is all you have to do for layout but I like to play a little bit. I move all the meta, summary, notes to the end and pick out a fun font for the title: 

Listen To Your Elders

No time like the present to do a quick proofread. Congratulations, you’ve just created your first typeset. On to the fun part.

Now you’re going to need some materials:  8.5x11in paper ruler one sheet of 12x12 medium card stock (60-80lb) scissors pencil pen or fine tip marker sheet of wax paper white glue two binder clips 2 heavy books or 1 brick butter knife

You’ll also need a printer, if you’re in the US there is almost a 100% chance your local library has a printer you can use if you don’t have your own. None of these materials are expensive and you can literally use cheap copy paper and Elmers glue.

Print your text block, one page per side. Fold the first page in half so that the blank side is inside and the printed side out:

Listen To Your Elders

use the butter knife to crease the edge. Repeat on all the sheets. When you’ve finished, stack them up with the raw edge on the left and the folded edge on the right. I used standard copy paper, because you’re only printing on one side there’s no bleed to worry about. Take the text block and line everything up. Use the binder clips to hold the raw edge in place.

Wrap the text block in the wax paper so that the raw edge and binder clips are facing out. I’m going to use my home built book press but you don’t need one, a brick or a couple of books or anything else heavy will work fine.

Listen To Your Elders

Once the text block is anchored down, take off he binder clips and get out the glue.

Listen To Your Elders

You can use a brush but you don’t need one, smear some glue on that raw edge.

Go make a margarita, watch The Mandalorian, call your mother. Don’t come back for at least an hour

In an hour smear some more glue on there and shift your brick forward so that the whole book is covered. This keeps the paper from warping. While glue part 2 is drying we’ll do the cover. Get out your 12x12 cardstock

Listen To Your Elders

Mark the cardstock off at 8.5 inches and cut it. Measure in 5.5 inches from the left and put in a score line with the butter knife (the back edge not the sharp edge)

Carefully fold the score line, this is your front cover. You have some options for the cover title, you can use a cutting machine like a cricut if you have one, you can print out a title on the computer and use carbon paper to transfer the text to the cardstock. I was in a mood so I just freehanded that beoch. Pencil first then in pen.

Take your text block out from under your brick. Line it up against the score mark and mark the second score on the other side of the spine

Listen To Your Elders

Fold the score and glue the textblock into the cover at the spine. Once the glue dries up mark the back cover with the pencil and then trim the back cover to fit with your scissors.

Voila:

Listen To Your Elders
Listen To Your Elders

I’m going to put this baby on the shelf next to the Silmarillion.

The whole process, not counting drying time, took less than an hour.

If you want to make a book of a longer fic, I recommend Renegade Publishing, they have a ton of resources for fan-binders.

Asperitas and Mammatus

Well-defined, wave-like structures in the underside of the cloud; more chaotic and with less horizontal organization than the variety undulatus. Asperitas is characterized by localized waves in the cloud base, either smooth or dappled with smaller features, sometimes descending into sharp points, as if viewing a roughened sea surface from below. Varying levels of illumination and thickness of the cloud can lead to dramatic visual effects.

Occurs mostly with Stratocumulus and Altocumulus

Mammatus is a cellular pattern of pouches hanging underneath the base of a cloud, typically cumulonimbus rainclouds, although they may be attached to other classes of parent clouds.
