# Science notes

RadMaths home page $\text{Note created on 2021.5.4, Tuesday}$ Here I will be posting a course on science. The whole thing should be ready in a year or so :)
All content is handwrited :) feel free to comment below if you find any problems :)

Sorry that the pics are small :/ I can’t modify them :/ just adjust the size of your browser :)

Explanations are more than just a solution — they should explain the steps and thinking strategies that you used to obtain the solution. Comments should further the discussion of math and science. When posting on Brilliant: • Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused . • Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone. • Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge. • Stay on topic — we're all here to learn more about math and science, not to hear about your favorite get-rich-quick scheme or current world events.

i was acutually just about to mention you dude! cuz i prepare to write something about simple machines(springs, pulleys) later on, and i couldn't list them all out! could u help me?

- 2 months, 3 weeks ago

Of course I would love to^_^ ,why are u even asking ʕ º ᴥ ºʔ

A teeny weeny bit on springs that I just remembered

• All springs work because of restoring forces acting on them that tend to restore the spring's configuration.
• The restoring force is directly proportional to the displacement of the spring from its mean/equilibrium position (larger the force,larger the displacement).
• They somewhat are related to waves (spoiler alert) but that's a really interesting topic and I don't wanna spoil the fun and will be talking about it in detail later :).

thanks! what other kind of machines are there ? (im going to write this out so im paranoid of missing anything) you dont have to explain to much :) just listing them out would be ok :)

- 2 months, 3 weeks ago

Ohh okay!

Pendulums,trolleys,wheels on an inclined surface(rolling/sliding),Guns, airplanes,collisions of object with varying masses,lifts/elevators,ships/sailing vessels,etc

Nice! Thanks!

You're welcome:)

I mean those simple ones I can explain in physics so yeah, that’s enough :)

How many pics can you see now? I uploaded six, but I can only see four!

- 2 months, 1 week ago

Three ...only three

- 2 months, 1 week ago

Oh yes, three... each split into two if you look carefully. Must be the problem with my browser since I only see TWO pages :D

What’s wrong with the king? Is it overlapped?

What’s really funny is it doodles hilarious stuff that makes people laugh... u know what I’ll read it for a few minutes and perhaps it will load :)

- 2 months, 1 week ago

Yeah sounds like a greta idea:)

@Brilliant Mathematics is there a way to enlarge the size of photos through codes? Because I find it very annoying to adjust the size of my browser every time I read this :/

- 2 months, 1 week ago

Hi Jeff. You can adjust the image size as such:
