I'm also interested in this as someone who doesn't have a math background

>>7974898
Operators are specifically between vector spaces

functions can map between any two sets

All operators are functions but not all functions are operators. A function which maps a piece of fruit to its colour is not an operator.

>The former is as much of a science as Engineering. The latter is as much of a science as Mathematics.

Engineering isn't science at all, it's solving problems using science, only rarely do we contribute to science directly (an example from my field would be Oliver Heaviside), it's mostly developing tools and ways for scientists to do the science part.

As for 2 I'd say it's true if those are done correctly, stanford's ML for example is cringe worthy

>And to each their own, personally I think Mathematics is a science, because even though it's a completely abstract construction ("it only exists in our minds"), it can be considered a non-physical property of the universe because our minds are a part of the universe.
You heard it here first, """"quote"""" fags think mathematics is a science and are therefore confirmed cancer.

>>7975354
For example, prove that some theorem is not true. You can't. Therefore math is a science.

kek, well played. But yes, we should ban the brainlet for all forms of high office and anything above menial labour [spoiler]until we can replace them with robots [/spoiler]

Probably they should be encouraged to spend their time on websites like 4chan or Reddit, so that they don't unnecessarily burden normal people.

They should be sterilised if they're not already, and allowed to do what they want but not given any advantages

The more recent MSci degree, now offered by UK institutions, is an abbreviation for Master in Science. It is equally reputed and acknowledged by employers within the UK and internationally. According to the UK National Qualifications Framework, an MSci and other such master's degrees (MPhys, MChem etc.) are termed integrated masters and are classed as level 7 qualifications—the same level as a Master of Science or Master of Arts degree.[3]

Stepping stone to getting into a better PhD program than you could otherwise.

>>7974779

BSc includes all your prereq, english, math, chem, physics, literature, history, diversity, international stuff
MSc is bringing all that together to understand a very specific topic with extreme concentration
You don't need to be smart to get either, but they are completely different academic experiences

Make your own choices you stupid dumbfuck

Ask him how it feels to get Neils sloppy seconds.

Ask him about the moon landing being faked. He usually gets a kick out it and will shake your hand if you do.

>and math
Leave math out of this. These words mean something different in math.
They mean different things in science too. You need to specify and define what the hell you're talking about. Otherwise this is just gibberish.

Pop religion, no troll. Imagine a world without it!

>can a negative
No. Now guess what I'm saying no to.

>>7974631
At least PDEs

>>7974631
Chaos theory adds an interesting perspective.

vector/coordinate stuff, matrices a lot, numeric methods, different approximation methods for simplifications(perhaps software specific), a bit integral stuff

FEM and CFD are quite similar in terms of math

Biology a best.

Djikstra is one of the few people actually worthy of calling themselves a computer scientist. Knuth is a meme.

>>7974600
I googled this guy, and his quotes seem to be the most famous thing about him.
Cool.

More specifically, I'm looking to get into extremal combinatorics. I haven't worked with this stuff at all before, though, so any sort of introduction would work just as well.

Too bad, here read COMBO.

I'm not really looking for proof autistry. I'm focused on actually doing useful things with it instead of solving cute little math puzzles.

We might still evolve. But it prob would be very different

Without the chicxulub impact event, small marsupial creatures would never have had the chance to become dominant.
Then there wouldn't have been mammals like us.
Human intelligence is just a random happenstance. If countless variables had been slightly different we never would have existed.

We didn't evolve as tool users until the last million years or so, long long after that event. And we certainly had predators.

I'm assuming that "you" would be an evolutionary product of a world orbiting a star near the center of the Milky Way, in which case, no. You'd be very well adapted to it.

As for a human, you might have a hard time if you're camping. The night sky would be bright enough to comfortably read by. But, of course, you could always go the fuck inside and use some blackout curtains on the windows.

>>7974364
There is a supermassive black hole at the center of the galaxy surrounded by stars too large to harbor terrestrial worlds like earth
Nobody lives there

Yes, it's hard to sleep when you're dying of radiation sickness.

teach me the ways senpai

Bump
Someone lay it on this man

Dilution by magnetic filtering.
Although you'll need a looooooooot of blood to make a knife from blood. And the extraction process will probably take time as well.

About .01% of the body is comprised of iron. So assuming you find a 150 pound man, you'd get around 6-7 grams of iron. so you could make a really small dagger. Like really really small. As for the actual amount of iron you need to make a knife of any particular dimension, i am not sure, but you will surely need more than 7 grams

>>7974143

Can it be done /diy/, or do I need expensive science equipment?

>>7974149
I'm asking how to extract iron and you literally could not or chose not to comprehend my question. I already know how much iron I need to make a sword and on average how much iron I could get out of a deer or bear.

Homework threads are against the rules faggot.

Why come they replaced numbers with letters in Algebra?

I'm looking for a categorical semantics of objects (as in object oriented programming).
I've found two papers with that topic in the title but haven't looked at it yet. But if someone knows or thinks about it, and wants to do a rant, that would be neat

(I'm writing a GUI for talking with spectrum and network analyzers, but in Python, and I'd like to promote the flowcharts and brainstorming bubbles to typey diagrams)
