7 years IMO. There is very little content in the math you need to know before calculus. However, this content is very, very important, and usually when people are struggling in calculus, it's the algebraic manipulation and trig they are actually struggling with.

Get things like properties of exponentiation, logarithms and such down. Note also that this is not a memorization task (though you should have them memorized with time) since everything can be re-derived from definitions and axioms. Trig identities are super important too.

Once you're done with calculus, you're at the "typical mathematics freshman in university" point, and university will get you ready for graduate school in 4 years. That 4 years is a lot of dedication though; I was setting aside 40-60 hrs / week every semester through undergrad for math alone.

There are some random things are worth committing to memory btw, just for the sake of pattern recognition. I'd be able to recognize powers of 2 up to 2^12 and powers of 3 up to 3^6 and small powers of other numbers too. Also all perfect squares up to 25^2. Decimal expansions of small square roots like root(2) and root(3) and common trig decimal expansions like root(2)/2, root(3)/2, and pi/3, pi/4, pi/6.

study cellular biochemistry and find out

Firstoff, people don't breed bacteria, scientists force bacteria to absorb and use DNA they find in the petri dish they're in.

Secondly

If Cancer could be detected so easily by the body, macrophages would eat them, some autoimmune signal would get triggered, whatever,

If cancer was easily detectable by cells, the cancer would be gone

>>8965132
it's really, really easy to find bacteria that will eat cancer.

what's wrong with RREFing the matrix and the identity at the same time?

>>8964337
Well you can lift it, so get some weights and just start adding weight until it feels about the same. Done. Alternatively find the density of concrete, measure its volume, then just multiply one by the other. Now, why the fuck do you care?

>>8964347
The first one isn't accurate enough and I don't have enough weights, I did the second and got too high a value.
I don't know why I care, I was bored

Just make scales like this, you really only need a big plank for that and something to hang it on or a rod to balance it on.

Can you believe if we were just a meter closer we'd all burn to a crisp?? Crazy. It can't be just chance...

They literally scramble to make shit up to salvage their dear theories when reality disagrees.

Theoretical physics is absolutely science fan-fiction

>>8964127
String Theory originated in trying to develop a theory of the strong force (before QCD was a thing). It was an accident that it happened to be a "working" model of quantum gravity.

yes, it's natural to fear change, but also natural to embrace the positives that come from it

We should fear being careless with it.

No. AI will never be a problem. It is too limited and will always be too limited. People project to much of their humanity/animalism onto strong AI.

Excuse me, biology and medicine is prohibited here.

This subreddit is reserved for physics and math majors to jerk each other off in peace.

>>8962402
well all the sciences spread out from physics right? they should have no problem answering this.

>>8962372
Yeah, we can look at objects and stay focused at smaller distances, thus increasing detail resolution. When I want to probe very small stuff, I sometimes remove glasses

the cancer epidemic is intentionally ignored as it culls the population as was historically intended

Cancer is pretty unavoidable in high age. FIxing heart disease just makes it more likely that someone will get cancer instead in the lifetime they have gained.
Cancer is damn difficult to cure, so don't blame politics for it.

>>8961796

lifespan in US remained constant while cancer rates increase to 80% of the population.
