What are the best mathematical books? What do you recommend?
Not OP, but let me make a different question: How can I identify/know which books are horrible for learning? There's thousands of books for math, for example, how can I know which is good and which is not? Amazon reviews are not the best source for this, sadly.
If it's a Pearson book it's complete and utter garbage and you shouldn't spend a penny on it. Don't let anyone tell you Pearson publishes any good textbooks, some cucks may throw University Physics by Young at you, but it's an awful book and just happens to be the book they were pigeon holed into in their high school physics class and so it's the only book they've ever read.
What is time anon?
I need some help, /sci/.
Does this make any sense to you?
Stopped reading at "Mario bump operator"...
I have this plane kit to develop pic related with a team of friends. It'll take a couple years, and of course we will develop a normal engine for it.
But I'm really interested in nuclear power. I know how to get good amounts of Uranium and Deutrium , more or less legally and illegally.
How much power would a nuclear engine need to generate to power pic related? How big would that engine be?
>How much power would a nuclear engine need to generate to power pic related?
i never got why people asked shit like that. how much power does it take to operate? and what does uranium have to do with fusion?
either way its not really feasible
Sorry for the retarded question, but isn't pi:
4/1 - 4/3 + 4/5 - 4/7 + 4/9 - ... = Pi
1/2 - 1/4 - 1/8 - 1/16 - ... = 0
Pi, like 0 will have a number you can write out completely, we just don't know how to work out the exact circumference of a circle so we use approximations.
Am I right in thinking this, /sci/?
Was consciousness a mistake /sci/?
Imagine the disappointment of finally making it out into the universe at large; only to find out we are the only organisms to have developed a conciousness and that it's an evolutionary dead end.
I disagree. Consciousness is what makes us strive for abstract answers that offer no immediate value, and the search for these answers indirectly results in technological innovation. Clearly humans, being the only conscious (let's assume) animals, have made an incalculable leap in advantage over other species.
Why are there more male female-foot fetishists than male female-hand fetishists?
Background: Someone told me that the seeking of female fertility markers (such as symmetrical features, ample breasts, lustrous hair) was the reason men find feet attractive.
The reason men find feet attractive is due to the location in the brain that controls our feet is right next to the portion of the brain that's responsible for our genitals, so the wires get crossed often. Men have higher sex drives, so that's the reason foot fetishes are more common in men (women would just get a pedicure if they wanted to feel good)
I am a mathmatician who has been put in charge of a largeish engineering project despite my complete lack of qualifications. I will take control from the old team leader on Tuesday.
How can I be a good manager and not piss off my engineers?
details to follow
I am incharge of 7 junior engineers who pretty much can only build basic shit, 3 highly competent "old hands" who can do anything, 2 electrical engineers and one aerospace engineer.
We are building a small one-seater car.
This was my organisational plan so far, I figure I will only have to keep in regular contact with the "Heads" of the various project parts, each of whom are very competent. Does it seem ok?
You're not there to micromanage them.
Especially since you admit you are underqualified, you're not really in a position to second guess them and you already understand that they are better engineers than you. That shouldn't stop you from floating ideas out there, but don't be the PHB who suggests things beyond the realm of possibility or deadlines.
You're there to remove any impediments the engineers face when completing the project. You do all the bullshit bureaucratic administrative stuff so the engineers can focus on what matters. Do...

/sci/, I'm a little scared right now, though not in pain. The feeling seems to be subsiding.
I had just taken a bite out of some candy bar I never tried before. it might not be related, but now my neck and jaw area feels and sounds as if filled with crushed glass. It's not painful, just the soun and perhaps a slight stiffness.
I'm typing this standing up and the feeling has gone away. What the fag just happened? Allergic reaction?
When filming a Samsung Galaxy s6 edge, or any device with a similar display probably, -I just happened to see this one- there's light stripes floating from the display's bottom upwards. It's probably nothing unusual, but what is this effect called? And why doesn't this appear when filming an iPhone's display? (Both were in the same video)
if i lived in california and there was a drought, should i cut my water usage? would it change anything? i'm thinking not because there's millions of people living in california. if i wasted 1000 liters, that would amount to like a drop when divided amongst all the people that lived in california. it makes no difference
Use as much as you actually need. No more and no less. The government pays people to ensure you have your water and you pay taxes so that the government can pay those people.
But if you waste water then I hope you get cervical cancer.
yeah, but my question is whether there's a way to model this in which it can be concluded whether the amount of water i waste has a significant impact, given that i don't waste millions of liters
You cut down your water usage by [math]x[/math]
There is now an extra [math]x[/math] amount in the reserves for everyone else to use. Thanks to your contribution, everyone else gets [math]x/y[/math] extra water, where y is the population who get their water from the same place you do.
That number will be really small, but if you assume that other people do the same then it becomes significant. If you actually care then just put up posters in the streets telling people to cut their usage as well.

>tfw Planet Nine is finally discovered
>tfw it's gonna be discovered by some Cuck who will name it after something not related to Roman Gods
Seriously if the names for Minor Planets or other objects in the Solar System is an indication expect the new planet to be a combo breaker.
> Finally discover Planet X
> It's 10 times larger
> It's the tenth time someone's found a planet
> But because some cucks downgraded the last one...
> OMG GUYS WE FOUND A -NINTH- PLANET THIS HAS TOTALLY NEVER HAPPENED BEFORE
Don't worry, Uranus was supposed to be named George in honor of King George III, by its discoverer Herschel. And Neptune was supposed to be named Le Verrier. We all know how that turned out
There's a weird issue me and my friend would like to know the answer of. How fast, and how long would your eye lashes need to be, to actually start flying with them. Let's assume the world operates in super slow motion and you're in usual time to compensate. How fast would you need to blink with your eye lashes (let's call them Eye Bashes Per Second (EBPS)) to start flying? How long do your lashes need to be to create viable flight with the EBPS in question?
This sounds like a troll and we know it's impossible, but humor us with theoreticals.
Can someone tell me why this is newsworthy?
I mean it's not the first time Planet X has been hypothesises it exist.
Seriously are people so casual about astronomy or something?
I knew about the possible existence of this planet for years & years.
Suppose you have multiple usb ports in a bus. You must connect them parallel, so that if one fails the other will work.
So the voltage on all the ports is the same, but the current will be lower.
Is a battery charges like a capacitor? The higher the current the faster it charges?
Why is there optimal voltage on batteries?
It has been a while since i studied physics in school so please explain this to me
