Someone could kill you by holding your nose

And breathing through your mouth is essential for any kind of physical effort.
Running to hunt your prey or escaping from a predator is millions times more beneficial than not choking on food even if you're a retard who can't eat properly.

Is this book a good starting point for someone studying proofs for the first time?
Can you guys recommend some other intro to proofs books?
>>7833056
This is my favorite intro to proof book.
It's very short, very well-written, and covers some useful (and interesting, in my opinion) things as well rather than the contrived examples many how-to-prove-it books are filled with.
It's also cheap, which is nice.
Keep in mind that there's very little to actually _learn_ about doing proofs. Only a few pages.
The important part is to do a fuckton of them to get experience with writing and reading proof.
How can I calculate the volume traced by a circle in R^3 that rotates x radians while translating a distance d along a line? (center of circle stays on the line)
At the start the circle is oriented along the xy plane and it's translated along a line in the xy plane while rotating "forwards". For example if r=1, x=2pi and d=0 it's obviously a unit sphere.

You don't pick your parents, you don't pick your genes, you don't pick the environment in which those genes were expressed, you don't assemble the micro and macro structures of your brain which decide every conscious and unconscious action you will make in your 2.5 billion seconds of life, you don't choose the thoughts in which you think.

Faggot.
Check mate.
>>7825360
it's not like we are trapped in our bodies, we are our bodies, so the result of our thought processes is our free will. It's not free from the laws of nature, but then nothing is, so it's pointless to expect somethign else.
You expect some kind of divine/transcendent qualities for free will, but that isn't a necessity at all.

Does anyone have the paper? Still can't believe the cat sees us as big cats
>>7824438
It is from 1999, I coud not find a digital version.
But it is a legit Berkley experiment.

Did they comment on that big cats thing? Is it an accepted fact that I wasn't aware of?

A train originally has no passengers on it.
The train stops at villages [math]v_1, v_2, v_3, \ldots [/math] respectively.
At each village, 2 people board the train and 1 person gets off.
After visiting all the villages [math]v_i[/math], the train gets to village [math]v_\omega[/math]. How many people are on the train at that point?
______________
Side-note: If you don't believe the train ever gets to village [math]v_\omega[/math], think of village [math]v_i[/math] as being at location [math]\frac{2^n-1}{2^n}[/math] on the real number line, and village [math]v_\omega[/math] as being at location 1 on the real number line. Imagine the train moving at constant speed across the interval [0,1], with people hopping on and off the train arbitrarily quickly at each village. Clearly the train reaches village [math]v_\omega[/math] in finite time.
There are two types on infinity - countable and uncountable. Your thought experiment relates to the countable type.
Watch from the 2 minute mark; or watch it all, its an interesting video.

So what's the answer then?
>>7815585
The answer is that you don't understand infinity well enough to ask a coherent question.

I know M.D. Programmes are not easy but come on.
>>7811028
Nobody has any kind of understanding of what a doctor of physics does. And a lot of them who do simply do not see it as important as what doctors do. On the other hand, everyone has seen a doctor. Everyone has seen how one of them 'saved' their lives or maybe someone else they know.
However, there is an underlying question here.

Holy fuck. An insightful answer on sci to a post like this?
Are you ok anon?
So due to the theory of special relativity, the speed of light in vacuum, c ~= 3x10^8 m/s is the fastest speed possible, but emitted photons do not accelerate up to that speed right? It's just an instantaneous electromagnetic wave. I know that photons can be affected by gravity which gives them acceleration ( change direction of velocity), but I'm talking about when an excited electron returns to its ground state by emitting a photon, the photon just appears i to existence already going at the speed of light. Is this correct?
What is the difference between the cyclo/synchrotron and particle accelerators like the LHC?
What is the highest %age of c that humans have been able to accelerate a massive particle to?
Is there a limit to acceleration in the universe like the limit of c for speed? Is it possible to accelerate a particle at 3x10^9 m/s^2 for 0.09 s to get it to 0.9c?Or even at arbitrarily larger accelerations than that for even smaller time intervals?
What would be the limit to acceleration? The magnitude of the force and so the energy needed to create that force?
Too many questions.
Realistically, how would you solve the overpopulation issue? Mass killings, forced migration?
Personally the idea of chemicals in the tap water reducing sperm count appeals to me

So we have yet to come in to contact with aliens. I do believe they exist.( virtually impossible for them not to) but what if they don't exist... Yet. There has to be a first everything. What if it is us?
