Sup /sci/. 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?

Newton was literally retarded compared to a modern normal person. The average hoodlum could have come up with principia. What trash.

/pol/ never ceases to amaze. Every time I think they have reached the ceiling of stupidity, they just raise the bar even further. Congrats

They seem to cite top scientists talking about the photon cloud earth will pass through very soon.

What is that photon cloud?
Can /sci/ pls explain the topic to a pop sci pleb?

Why some fiction depict aliens as having no morals or being completely logical beings?

How could a biological species not develop moral and ethics since both have biological grounds?

How could the same forces that gave rise to life in earth make extraterrestrial lifeforms that doesn't share the same basic foundation as earth beings?

>huh duh diferent planets
I still don't believe why pack and group behaviour in alien animals will be diferent.

pls /sci/. i know you can do this :c

anyone?

>what does /sci/ think of the intangible, of things we can't measure?

It's not bullshit, but it's not really what men of science explore (i guess neurobiologists kind of touches the subject, but only the measurable) but the things you can't measure isn't really what we do. It's like asking a scientist what he think's about architects.

It's all good.
I'm attending Cornell, and waiting on the Stttanford waitlist, so I'm just anxious as all fuck. Anything to make myself feel better.
