How to Really Comprehend a Scientific Paper

**credit to my research advisor, she’s an amazing mentor and I aspire to be just like her someday :)

Read the abstract. Write down what the paper says it is going to be about.

Read the introduction. Write down what the paper says it is looking to accomplish and how.

Read the conclusion. Write down what the paper actually did accomplish.

Go through and find all the pictures, graphs, or diagrams. Write notes explaining these images to yourself.

Read the whole paper start to finish. Write a summary of the paper as though you are explaining it to a layperson, and then another summary as though you are explaining it to a colleague.

Throughout all of the above steps:

If there are words you don’t know google them and write down the definitions

If the paper defines a formula, law, variable, etc in a certain way write that down

If there are references to or recommendations of other literature write those down. After the last step if there’s anything you’re uncertain about or would like more information on look to that list for further reading

So I keep seeing posts on studyblr about how to take notes, some of them “official” methods like the Cornwell method or whatever it’s called, others more based on personal experience/ideas, but basically all of those don’t work well with math and physics.

So I made examples of how I take notes in physics and math, which based on what I’ve seen from professors and other students is pretty standard. (Blue text is commentary on the notes)

In math always start by defining the variables, because you will forget and you need to know all the assumptions you’ve made (like “did I define the function f as continuous, differentiable, bijective or just continuous and bijective?”). Drawings are good since they help visualise the abstract stuff (and look pretty), but not necessary. Always write down definitions, theorems, and lemmas, and ESPECIALLY their proofs. Exercises (both proof exercises and application exercises should be written down too, with varying detail based on how easy it is for you.

In math, and a bit less so in physics, you should always try to use mathematical symbols to shorten text. For the theorem I wrote what I would actually write in white, and below in blue I wrote the full, no symbol version of that. It’s pretty obvious which will be written down faster in class.

And never forget to write that sweet little quod erat demonstratum square at the end of a proof.

In physics the only thing you ALWAYS have to write down is a work through of an exercise or proof (this, of course, includes defining the variables, unless you’re the same variables as last time and can refer back to those). Since physics is about THE REAL WORLD you should strive to draw diagrams constantly, since sometimes you won’t be able to find a solution until you draw the diagram and examine the system (some proofs, especially those in optics, rely heavily on diagrams to explain what the fuck is even going on).

Unlike in math, in physics everything has a unit, which you should ALWAYS mark SOMEWHERE, because you might figure an exercise out solely based on your knowledge of units.

Pass along and use the shit out of them

last minute orgo studying before my exam; i did a study guide of every single topic covering the most important reactions and their mechanisms; ಥ_ಥ  it was worth it! 

Astronomers are the funniest people on earth actually

This is the best use I have seen of a composition notebook without the pen and highlighter bleeding through! Stunning!

some more notes

Optical Astronomer: chronically tired, hates clouds, hates the sun

Radio Astronomer: sitting in the shade sipping lemonade while the big dish goes wheeee at 10 am

X-ray Astronomer: cries about the cost of a satellite launch

Hey remember when US and Russia was all like “We’re the best!!! We’ve won the space race!!!!” But India sent a kick-ass space probe to Mars and the whole mission was fuel efficient, costed less and a roaring success in the first try and then they were like “…..wait no that can’t be true” and still have the audacity to call us “underdeveloped” or only view us as a ‘third world country’? :)

For anyone who needs more info, the probe was called Mangalyaan (which literally means space probe vehicle) or Mars Orbiter Mission (MOM) and you can also get more information here and here

The tails of Comet NEOWISE!! Comet’s usually have 2 tails that always point away from the Sun.

Here, NEOWISE’s blue ion tail on the left points directly away from the Sun and is pushed out by the flowing and charged solar wind. Structure in the ion tail comes from different rates of expelled blue-glowing ions from the comet's nucleus, as well as the always changing structure of our Sun's wind.

The other tail, the dust tail, is pushed out by sunlight, but curves towards its orbital path as heavier dust particles are better able to resist this light pressure. Comet NEOWISE's (Comet C/2020 F3) impressive dust-tail striations are not fully understood, as yet, but likely related to rotating streams of sun-reflecting grit liberated by melting ice on its 5-kilometer wide nucleus.
