Oooh, I Tried This Method In First Year Physics Too! It Was Very Effective, Since I Got Fine Details

Oooh, I tried this method in first year physics too! It was very effective, since I got fine details from the pre-reading, which was supplemented during the lecture! This method worked fantastic (as long as I kept a routine)! Good luck with it!

✨2/30 days of productivity✨

started taking notes on QM today. i think i figured out how i want to take notes this year (at least in this course); reading and taking a bit of notes pre lecture and then i made a column of space for adding things during the lecture so i don’t have to write everything down during the lecture, only the things i missed in my notes! this way i can focus more on listening and understanding during the lecture, i damn hope it works lol

Propagation of Error

When I first started in physics, I was utterly clueless about propagating error. After three years of college, I have a better grasp of it and feel more comfortable using it in the lab. Have a look if you’re having trouble with error propagation!

Error and Uncertainty

Error: an unknown quantity in the realm of the state of nature

Uncertainty: a parameter in the realm of our state of knowledge about nature

Type A uncertainty: statistical in nature (an example of this would be if you were launching an object 15 times and recorded each distance)

Type B uncertainty: not statistical in nature (an example of this would be a digital reading on a scale - no matter how many times you put the same object on the scale, you will get the same reading)

Random vs Systematic Error

Random Error

environmental fluctuations

equipment noise

natural processes

Systematic Error

environment: fixed beyond a relevant parameter

measurement technique: assumptions, experimenter bias

equipment with an offset or using equipment beyond its limits

uninformed choices

You can reduce random error by taking more measurements.

You can reduce systematic error through thoroughness, properly calibrating equipment, reading manuals, and ensuring reproducibility.

Basic Error Propagation

This is the standard equation for error propagation:

This represents the uncertainty in the measurement of some value x. Suppose you are measuring this value based on this equation:

You took three measurements, a, b, and c, and plugged them into this equation to get x. However, there is some uncertainty associated with each of these three values. Let’s say you measured a on a scale, b on an oscilloscope, and c with a ruler. There is uncertainty associated with all of those measurements. When you’re reading the scale, you read it as 15.45g. Let’s assume there is an uncertainty of 0.01g in that reading. Similarly, you read your oscilloscope to be 3V, and there is an uncertainty of 0.05V. You read your ruler to be 3.45cm, and there is an uncertainty of 0.05cm. We now have our uncertainties for the three values:

a = 15.45g +/- 0.01g

b = 3V +/- 0.05V

c = 3.45cm +/- 0.05cm

The other aspect of the uncertainty equation is taking the partial derivative. Those are the dx/da and dx/db parts of the equation. We will take the partial with respect of each term.

The partial derivative of the equation for x with respect to a is 2a2

The partial derivative of the equation for x with respect to b is 2

The partial derivative of the equation for x with respect to c is 4.5

Now, we can plug into our equation:

Your uncertainty in your measurement for x is +/- 22.86.

I hoped this helped you if you’re struggling with uncertainty!

Romanticize your education

the midday stillness of a library

coursework sprawled on top of a desk

notes on the margins of a textbook

tracing names carved into an armchair

the inherent eroticism of the library after dark

a note falling out of a battered book

reminders scrawled across your hands

cursive handwriting

whispers cutting through the silence of the dormitory

the cold glow of a laptop screen in a dark room

ink stains

notebooks with half the pages crossed out

passing notes during lecture

getting up at 3 am to google something

leatherbound books with gold lining

crisp white paper

the smell of new books

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

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:

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:

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.

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

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

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

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:
