Smart people are being excluded from reproduction. Women choose to mate with the most brutal and anti-intellectual of all males. Sexual selection favors douchebaggery over intellect. Smart people will go extinct within the next generation. Welcome to idiocracy.

Why do we focus so much on Mars?

Shouldn't we be sending robots to Venus and other planetary-mass objects?

Mars is the most likely candidate to sustain life.
>>
Because Mars is the next logical step in the human expansion into space. If something were to happen to the Earth, a colony in space should be able to sustain itself indefinitely. It's much much harder to do this on Venus than it is on Mars. Mars has readily available water and other resources and we can live on or under the surface. Venus has none of that, and even if it does, it's not easily accessible.
>>
Venus is too dangerous. Mars is the most habitable planet for humans in the Solar System after Earth.

Could the reason why no one knows what happening to the factors of a number when adding 1 be because we defined x^0 = 1 ?

x^0=x^(n-n)=x^n/x^n=1

What is the difference between this and this:

suppose that a = b
then a2 = ab
subtracting b2 from both sides gives us a2 – b2 = ab – b2
factorising gives (a + b)(a-b) = b(a-b)
dividing both sides by a-b gives a+b = b <- Here is the problem, we are not allowed to divide by zero!
But also a+b = b+b = 2b, so 2b = b. Dividing by b gives 2 = 1

We are not allowed to divide by zero because it results in shit, yet we are allowed to exponentiate n-n which also results in shit. What am I missing?

we can't have that even in theory retard.

now making a shit ton of energy is something else, so nuclear is the way to go. harnessing atomic forces is the best way to obtain energy. we might find new elements work better than what we currently use, but other than that i see no other solution we can exploit

Here's a fun science question:

I am a male who is about 20 years old, and since around the age of 16 I have been able to cum as many times as my cardiovascular system and muscles will allow, over and over again, with no refractory period to speak of. Even when my penis eventually ends up completely flaccid, I can still coax more orgasms out of it if I have the strength left. The more times I cum, the better it feels. I used to count my orgasms when it first started happening, but once I regularly began to push the 20+ limit I stopped. I am able to orgasm multiple times in a minute, and there seems to be a slightly irregular pattern of smaller and smaller ejaculations as I get farther in, until nothing comes out. I have searched the internet for information about this, but I haven't ever heard of another man who is capable of the things that I am. Am I a freak of biology? Has anybody here ever heard of a man with no refractory period and unlimited, stacked orgasms? Please advise.

Some high school students who got extremely good grades in their finals (i.e. good enough for Medicine in non-American countries) decide to major in stuff such as Physics, Anthropology, Linguistics, Chemistry, etc. in the hope of doing research in the future. Why would they pick that?

>If you don't have anything published, your funding will be cut and you will have no income
>There is no guarantee that you will like research and most people hate if over time
>Jobs are meant to be monotonous, not fun
>They can easily major in Medicine, Law, Actuarial Science, Dentistry science, etc and switch to research later on or do a Master's degree in their area of interest
>The market for researchers is very bad at the moment - it is 100+ people competing for a tenured professorship post and it will not be you getting that job
>Being an adjunct professor sucks as all the contracts are short-termed
It is hard to even secure a mortgage with such unstable employment
>If you can't find any professorship job, it is hard to find anyone else to hire you as they know that you will go back to academia as soon as you find another professorship job, so chances are you will either end up unemployed or working at McDonalds during this time

These people get top grades in their finals though. Their marks are good enough for Medicine, Law, Acturial Science, etc. I am not talking about people who did poorly in their finals so they are stuck with picking Biology, Geography, European Studies, etc majors.
