Hello everyone!I have started a brand new Discord server dedicated to Math, STEM, and Physics enthusiasts. Whether you are working through High School Algebra, struggling with Calculus, or just want to discuss interesting Physics concepts, this is the place for you.We have dedicated channels for different subjects so you can easily ask for homework help or share interesting problems. Come hang out, study together, and help us build this community from the ground up!

I know there are probably a bit of people who don't like physics, or I am just wrong. Anyway, I just started out and to all those physics enthusiasts out there, I would love that you join my community Theworldofphysics. You can post doubts, theories whatever, just related to the topic. Those who are interested please join...

When wanting to find a particular equation, I often use dimensional analysis. For people who are just starting out in math and have never heard of dimensional analysis, well now you have. Suppose we want to find the formula for calculating pendulum time-oscillations, we need to find what influences the time. You might think of mass (kg) length (m) and gravity (m/s^2). kg does not match with any unit, meaning mass doesn't influence time. We cancel it out. We divide m with m/s^2 but dividing flips the fractions, m becomes the denominator. Ms cancel out and we are left with s^2. Take the root to get s and the formula you derived is almost identical to the real one. root of l/g. The real formula is 2 pie and root of l/g. Find more info on r/Theworldofphysics
