I'm wanting to learn math over again from the ground up but came across a series of weird operations while browsing algebra questions. I get how 2x2 is the same as 2+2, but how does something like 3×.75 equal 3-.75? Is there a name for this phenomena where signs can be switched out to achieve similar answers? This is stuff not really talked about in basic math as many operations are suggested to be accepted on assumption (like how when multiplying fractions we assume but don't ask why (1/2 x 2/3 = 2/6 )) >>TLDR; why does something like 3-.75 = 3×.75 and what is this kind of problem called? 9 replies omitted. Click here to view. >> >>10727728 This is basically the idea of two diagrams commuting (and thats about as deep as my knowledge of category theory goes). Definitely an interesting phenomenon, but its surely mean I'll ngless if you dont already know a shit ton of math. The very fact that youve noticed this and are thinking about these things as someone new to math is a good sign. >>10727867 >>10727874 Its definitely not completely a coincidence, but to get into the details that would take us very far afield into philosophy. The process is essentially nitpicking definitions but you can show that these aren't coincidences. In fact you could provide two different accounts: a set theoretic/model theoretic semantic account, or you could analyze the syntax of formal systrm youre working in and basically show that based on information theoretic properties of our base ten system that 3×0.75 = -0.75 >> anon I think I found the general case for all n [math]x=\sqrt{n^2\over (n+1)^2}[\math] i'm no wizard but thanks for the challenge! >> >>10727914 Do patterns and seemingly unimportant coincidences like this happen often in Math?

To add to that: more generally for any number x, there exists a real number r such that 0<r<1 and xr = x-r. Just graph f(x)=xr and g(x)=x-r and find where they intersect. Its what's called a fixed point.

It seems pretty god damn ridiculous that human intelligence being genetic is even a point of contention with our modern understanding of darwinism.
IF human intelligence werent genetically based it inherently would mean for instance, that it couldnt have "evolved" in the first place.
We would have had to have had the exact same level of intelligence as our primordial primate ancestors.
As our lesser mamal ancestors
as the fucking fish and bacteria we evolved from that didnt even have neuro system.
How the fuck is this a question in the scientific community?
The Ideal of genetic equality litterally flies in the face of the entire field of biologically since DARWINISM NECESSITATES INEQUALITY.

What’s the narrative?
>>
>>10727875
Skin color is phenotype. As is stuff like appendixes and eye color. The variations you mention vary a lot within a population, they're not really the major differences that can deviate on a species level and change generationally. Intelligence tests show intelligence rapidly changing by the decade as well. Developing countries in IQ surveys consistently show intelligence which catches up to developed countries. That shouldn't happen if intelligence is racially determined or that one's ability to learn is limited racially.

Phenotype differences don't include sweeping structural elements such as our brains growing for decades after we are born. As an aside, Skull shape I should note, does not correlate to intelligence. If you believe it does you minus well read horoscopes as phrenology is basically astrology for those who don't like hippie shit.

So you think IQ has no genetic component, so according to you any of us should be able to obtain a 200+ IQ then ?

Can anyone here give me an idea of what would be needed to move the moon? Lets say strapping rockets to it and pushing it?
>>
>>10726535
More than we could possibly get there with any technology we currently have can reasonably conceptualize
>>
The kinetic energy needed to move the moon substantially is on the same order as the energy required to break the moon apart; any movement of a planetary mass object would need to be done very slowly.

>>10726506
mass of moon = 7.342×10^22 kg
thrust of falcon heavy = 2.224×10^7 newtons
acceleration of moon from 1 falcon heavy = 3x10^-16 m/s^2
acceleration of moon from 10^16 falcon heavies = 3 m/s^2

We discuss research, offer advice (Just see your family physician), make fun of premeds, discuss residency and different specialties but we mostly shitpost.

If you want to discuss vaccines or clamping, please make your own thread because it takes a lot of replies and the discussion degenerates.

Path, clinical lab, onc, rad/onc, anesthesia

>What are the best specialties lifestyle wise?

Dentist here, so I don't know what the fuck I'm doing here, but my maxillofacial trauma rounds were pretty wicked. We were in Chicago and were trying to make mouths work again after assaults, car accidents, bullets through the oral cavity, etc. Often worked together with plastics and ortho for le fort fractures, dislocated jaws, and other mangled faces. It was something.

so /sci/ what is your number?

I'm feeling stressed out this summer since school starts on september 3rd and I feel like so much time flew by since May. I want to know what books I should read to help better prepare myself for calculus I in the fall during this summer, especially since that I plan to double major in Math and Computer Science when I transfer.

You should already know at least the first 2 semesters of calc if you are serious about math, anon is gonna have a lot of catching up to do same with already knowing everything up to data structs and algos in cs.

>>10727895
yes I in fact think anon is being a bit too gratuitous with choice to double major. although they explained they were a schizo-austist. that is a crude combination, they should just be a code fag and philosophy major as to support their insane schizo induced grandiose.
