I'm using strang's introduction to linear algebra and this book is extremely hard. like, I've gotten to page 35 in 2 days and I think i understood about half the stuff i read, none of the challenge problems. It doesn't help that there are no solutions for the problem sets...
Is this book supposed to be for first time learners? What did you guys use? Should I just bite the bullet and get through this book or opt for something more learners friendly?

i'll give it a try, hopefully it's clearer than this textbook
the sequence
89;82;84;85;80;9(nine);91;93;X;96
X=? and why :)
let's have fun
>>8207749
(45241/9)+-(1176407/90)x+(308340161/22680)x^2-(5330767/720)x^3+(1262363/540)x^4-(79561/180)x^5+(53129/1080)x^6-(237/80)x^7+(421/5670)x^8
is one solution. For x=1, you get the first number in the series. For x=2, you get the second and so on. The ninth tells us that X = -(8381/9)

How do you flatearthers explain the magnetic field and the reason magnets work?
Ha! Checkmate!
> How do you flatearthers explain the magnetic field and the reason magnets work?
Or gravity
Or sunsets
Or the edges of the earth
>Earth is round

>Earth exists
wow really makes you think tin foil cap

As a math fag, should I be concern that I know nothing about tensor calculus? Should I care about them in pure math? What's a good book on tensors?
>>8206924
You know that pure math is a big field? This question is basically unanswerable. You'll probably never use it for math, and if you need it then you'll know.
>>8206924
Tensor calculus is pretty much where linear algebra and vector calculus become one subject.

I made the mistake of eating two burgers and started feeling uncomfortable. I'd had some wine beforehand, so that may have contributed.
I began breathing rapidly and shallowly, and because of this, I was afraid I would vomit.
Breath control didn't work. My skin felt like cotton wool, which is how it usually feels on the rare occasion when I can't get enough air into my blood (high altitude, etc.)
But then I remembered the "mammalian dive reflex," which lowers heart rate in cold water.
I rubbed my face with an icecube until my breathing and heart rate slowed.
Placebo is possible, but this is digestion. It's about as concrete as it gets. My stomach is just as stuffed as it was before.
Why did this happen in the first place, and why did a cold face make it subside?

And once again pseudo-intellectual high school calculus kiddies think there's nothing more to integrals than the first trivial examples of the fundamental theorem they had to solve in school.

Are you on your phone OP?
Are humans brainlets?
>>8205519
Not because of brain mass, but yes.
>>8205519
Baiting faggOP, go home fisherman, you're autistic.
>>8205527
What would happen if a human was born with an orca brain? Would they be smarter than John von Neumann?
or would all the people living in the colony work for free?
>>8204984
resources would simply be rationed.
but who wants to live in a trash can
Why do we assume that the laws of nature is the same everywhere in the universe? Is it simply because we want deterministic models or is there more to it than that?
Why would you assume otherwise when we have never observed otherwise...?
>>8204260
Because sci-fi?

"It hasn't happened before so it never will" is not logical. Surely, there's a better answer than that?
What did they mean by this? What PRACTICAL limits does the scientific method have in principle, beside certain experiments being too hard to perform? Is there another method that fills in the gaps?
No mental masturbation please.
> Scientific method has limits
It's not the fact that it has limits, It's the fact that scientific method is the most reliable and logical method for finding out answers, which is why it's the only option.
>>8204171
>Is there another method that fills in the gaps?
no. If our current "understanding" of the world has shown one thing, it's that humans are notoriously bad at reasoning about how the world works in absence of any evidence in one direction or the other.
Science explains everything, except for where science contradicts my political ideology. In those cases, only continental philosophy is sufficient.
Why are the prime numbers and pi related?
What is the trigonometry behind such relations? If not trigonometry, then what specifically?
Pictured is just one of the relations.

Because they're a tool of the patriarchy and a product of millennia of misogyny and rape culture.
It's all connected.

What's the word for when you feel euphoric after thinking / saying something intelligent?

Normal.
Absolutely nothing

Isn't it weird how many people don't get just how weird it actually is to exist? I mean the odds are so ridiculous, it's amazing how unconscious most people are, worrying about trivial shit 24/7
sry that I ENJOY LIFE rather be a no life reading all these geek shit XD

Amazing insights OP

DUDE WEED LMAO
Why is it that science accepts that height is genetic and that it differs from race to race, but chooses to not accept that intelligence is genetic and that it differs from race to race?
>>8206884
Is this topic the only thing you come to /sci/ for?
Because there are already studies showing differences in intelligence between races
Also because there aren't many people who will pay them to do so, and academia is not some magical holy grail of objectivity
Because it creates political friction and it's discussion is of no benefit - and really only relevant to Gorilla posting anons with superiority issues and his real life equivalents
Is there any truth to this?
