Has anyone actually truly feared existence? What do I mean by this? Well here's what I mean: have you ever thought deeply enough to understand that existence in ANY FORM is scary? It's scary mainly because it's unexplainable and will never be explained. I'm wondering if you guys have ever thought this before as most other people havent (they're atheist or theist and believe in some form of physics or story that explains how the universe exists). I am personally agnostic which is technically atheist but as to how everything exists, I don't have any...

Laziness is a result of being highly intelligent. You realize that all human effort is ultimately pointless and irrelevant compared to the vastness of the cosmos, and thus do not see anything worth putting effort towards

Ok, so because of some timetable fuckery, I can only choose from two papers to add to my first semester of a physics major. This paper can be in classics, or in philosophy. So which one of these is ultimately more useless, and which one is ultimately more brain-numbing and uninteresting? Like to hear your thoughts.

Neither you dumbfuck. The only thing useless is your brain. Both fields will teach you how to think and view the world inquisitively. However, if you must choose one, I would go with classics.

What do you do if you've just found out you just 15seconds ago had unprotected sexual intercourse with someone who has an STD (let's say herpes)? Do you quickly run to the bathroom and soak your gooch in water and call the ambulance to get antibiotics or something? Surely there must be something you can do to reduce the risk of infection.

You know, just in case, I like to be prepared.
>>
I don't know the biology of it, so that missing knowledge would be a reason to wash my dick, yes.

I also know that a great bunch of girls have herpes anyway.

Herpes isn't that contagious when she doesn't have blisters. Washing won't do shit, and you could take antivirals for the rest of your life to prevent outbreaks but that's retarded.

Drinking anything you can that makes you piss a lot would probably help flush out your urinary tract. Other than that, I don't know, but I'm looking forward to see other answers.

Let $F:M \to N$ be a continuous map between smooth manifolds. I want to show that if smooth real valued functions on all of $N$ pullback to smooth real valued functions on $M$, then $F$ is smooth.

What's the way around this?

It's been awhile since I've taken any kind of calculus, so I'd appreciate it if someone could check this for me, since I'm working on my own at the moment to refresh what I've lost over the years:
If I wanted to find the surface area of a rocket nozzle with a curve modeled by the equation $3 + \left( \frac{\ln{(\frac{x}{2})}}{2} \right)$ with a domain 0.005 ≤ x ≤ 9 rotated about the x axis, would the equation be the following?
[eqn] \int_{0.005}^{9} 2 \pi \left( 3 + \left( \frac{\ln{\frac{x}{2}}}{2} \right) \right) \cdot (9-0.005)...

No, receding gums never grow back because they are a sympton of testicular cancer, which means that luckily for us, you will die in 2 months and thus will never propagate your shitt 2 digit IQ genes.

if there were an Atom made of one proton, one electron and one neutron, would it not be completely neutral in charge due to the proton and electron canceling out each others charge and the neutron being neutral... and thus not interact with what we understand as reality?

It occurs to me that the probability of there being atoms with every conceivable combination of particles becomes more likely the least amount of atomic weight and this particle, if it does exist, would be 2nd on the periodic table.

>>
>>7848996
It wouldn't be completely neutral. Your basic chemistry understanding of the model of the atom is wrong
>>
It would be neutral from far away. In the near field however, there will be fluctuations with time. Example: water molecules are neutral from far away, but close by they still attract due to their charge difference on the oxygen and hydrogen sites.
>>
>>7849015
What would constitute true chemical neutrality then?

my understanding of chemistry is limited to pool chemistry.

>if you don't understand something intuitively and find yourself keep asking for help about it, just give it up

This is probably the best advice I got but too late. I wasted years trying to get good at STEM subjects but to no avail. It was only too late that I realised trying to get good at STEM was essentially a sunk cost fallacy for me. I hope this helps someone who is in the same situation I was. If you're getting stuck and frequently find yourself asking for help for like a math or physics, just drop the subject immediately...
>>

it's not sunk cost because you develop the greatest problem solving ability from struggling through problems and finally solving them with a flash of insight.

I know 4chan is just trolls and people trying to bait eachother with discouraging advice and telling eachother to commit suicide but come on.

Ethnicity is a much older concept than that.

That's what I think as well, but how do I proof something that doesn't exist?

Can you break that sentence down to me a bit?
Do you locate those mutations in the current time or might they reach into the past?
