I can't seem to understand...

I can't seem to... 16 posts and 0 image replies omitted. Click to view.
Hey /sci/ bruhs. This is somewhat of a math related question, but, is there anyway to 'understand' math? Basically what I'm asking is: my mind can't seem to comprehend it. All of the 'advanced' shit. As if I am struggling at solving an alien language of some sort. I cannot solve problems mentally, so I have to rely on using calculators or even looking back at old notes to be able to solve 'em problems and such. As if my mind merely 'forgets' a day afterwards. Am I dumb?

Hi /sci/, so I want to have some math to do as a recreational activity in my free time and I got Calculus - A Complete Course 7th Edition, R. Adams, C. Essex but it seems I actually went through most of this stuff in high school. Where else can I go? I like geometry. Stuff that isn't about functions would also be nice for a change. Any recommendations for books?

Since the event horizon of a black hole is the point beyond which the escape velocity becomes greater than the speed of light, does that mean that any matter that's pulled in by a black hole's gravity is accelerated to the speed of light?

Does anybody have an idea to improve the cristalisation of a mixture of 7,5g sorbitol, 10g lactose, and 20g glycin per 100ml destilled H2O, during freeze drying, without preventing the sorbitol to turn amorphous first?

Sup, /sci/, /ck/ here. I have a little bit of a chemistry background, enough to roughly understand the reason brining chicken works the way it does, and enough to realise that it wouldn't work with saltwater fish. My question, then, is how would you go about 'brining' saltwater fish? (With the same end result of making the meat more tender and succulent)

Sup /sci/ I am trying to teach myself javascript right now. I am trying to make a calendar, but I haven't made much progress. I have some text and then a button underneath that text. When you click the button, the text should change to today's date. I'll attach a picture of my code. Do any of you know why this isn't working? I click the button and nothing happens.

Ayyee I came up with a bullshit theory and did a horrible job explaining it. I'm not sure if this theory already exists or not, or if it is just a smaller part of a larger theory. I understand how unlikely it is but do you fine gents think you could determine whether it is legitimately possible and tell me what to fix and change if it isn't? Molecule Expansion Theory Everything is made of a singular molecule that expands and collapses accordingly based on your position and perception of objects around you. V.2 Molecules multiply and divide themselves accordingly on your position to achieve their fully perceived form. Molecules in your vision's range multiply to take the form of a fully developed object and are perceived to have always been in this form. Objects outside of your range collapse into a single molecule to conserve space and energy in the universe. Expansion and collapse rate is measured faster than any moving object(s) and can be considered as phasing, sending energy and powering other molecules. This theory would explain the concept of Half-Lives. The more the molecule is perceived and acted upon, the less energy it consists of.

In a parallel universe, the Axis won WWII.
