#can you believe i forgot to tag my last post
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.
