how to deal with rubberbanding selfesteem?

half the people i interact with are way lazier and dumber than me - if I have to work with them my confidence goes sky high.

the other half are much, much smarter than me, and talking to them makes me feel like an idiot braggart.

I literally dont know anyone who is at my level, so to speak, and as a result i dont know how smart I am. Am I an idiot with delusions of grandeur or a smart dude with shitty selfesteem? Do i need to push myself harder?
>>
for me personally, I just keep my head down and work hard and try to have fun while I am at it

I could say I am smarter than others, but everyone thinks that. And since Im not some great innovator and my life isnt astounding, I remind myself to just be humble

>most likely delusions of grandeur

I'm having discrete math next quarter and I would like to study in advance.

Good discrete math books?
>>
Let's just go ahead and solve all of these threads at once:

>go to well regarded university's website
>navigate to math homepage
>find course listing
>click on course of choice
>read page to find the textbook they use
>>
>>7783321
Mathematical entities are indispensable to our best scientific theories, therefore we should think of them as real
>>
>>7783321
If you want to study in advance for a particular course you should probably use the book the course uses

discrete math is a usually a potpourri of random shit, although with a big chunk of combinatorics; topics covered vary a lot.

Is a scientist with an interest in art less intellectual than a pure scientist because the former wastes time with non-science? Assuming both have the same IQ.
>>
no, just because someone doesn't devote all of their time to science and math doesn't mean anything about their intelligence. In fact, studies have shown that people who take an interest in art have a higher-than-average intelligence.
>>
>>7783294
OP stated both are equally intelligence. His question is about intellectualism. Nice reading comprehension, brainlet.

Are there any physical laws that are exact? How can we know if one is?

To clarify, I mean without taking into account universal constants that we only know approximately, and given the perfect situation in which the laws are (supposed to be) valid.

For example, we know Newton's 2nd law is only an approximation valid for low velocities, but if we consider relativity, can't the v^2/c^2 term in the gamma factor not possibly be v^2.0001/c^0.0001?
>>
>>7783269
>Are there any physical laws that are exact

That's not the point of physics.

But from (unprovable) symmetry: conservation of linear momentum, conservation of angular momentum, and conservation of energy are absolute.

The space that holds the matter is infinite by definition. The matter inside is finite.

How can space exist if it's not matter?

>>7783225
That's like asking, how can energy exist if it isn't matter? The point is, it is 'something', an undefinable something.

>the real volume (excluding inflation)

What does that mean?
>>
>>7783026
put it in a body of water
measure displaced volume.

this is middle school physics bruh
>>
>>7783037
The actual volume/size of the universe, as it was pre-inflation. I'm not talking about "it was smaller than an atom!", I'm talking about some way to measure it relatively to something that isn't affected by inflation; a constant.

After that you can determine and possibly predict the rate of inflation. When you find that inflation variable, you can also determine the exact limit of the speed of light, for an example, since what we currently have as C is scaled up as space inflated.

How much confidence do you have in modern society to overcome the increasingly daunting problems of achieving sustainability with the Earth?
>>
I have every confidence in the future of humanity. The reasons are best explained in this manifesto, which I highly recommend you read.

http://www.ecomodernism.org/

Key reasons;
- increasing development leads to less environmental dependence, and therefore impact, per capita
- the world has reached 'peak child', where global fertility rate is a stable ~2.6 children per woman. Result; better education and opportunities for children resulting in rapid development.
- projected global population at end of century is easily fed by farming current farmland more efficiently (inefficiency in developing world is staggering due to poor access to modern agricultural technology)

Does anyone know if an algorithm exists for reducing complex numbers.

reducing to reach what form?

$a\,=\,b\,q\,+\,r$ where $q$ is the greatest complex number smaller than $\lfloor \frac{a}{b} \rfloor$ and $0\,\leqslant r \,\leqslant b\,-\,1$.

seriously why doesn't he have a nobel? he has more cultural significance than any other scientist alive. so he must at least be on the shortlist.

How does anyone with a basic grasp of space and scale come to that conclusion?
