What kind of experimentation? The sort that would be unethical if performed on people?

If it was demonstrably sapient, then no.

>The sort that would be unethical if performed on people?

I'm thinking social sciences. Thousands of AIs in a double blind randomized controlled experiment. On one side, you have a control society, and on the other side you have an experimental society, where you change some policy like taxes or a regulation to look at its effects. Time would be accelerated and we will be able to see its effects in 5, 10, or 20 years.

Then they would be reset.

I try to take it easy on the snacking, though. It's easy to get fat.

Back when I took QM, I'd stay up all night and go through a box of donuts before 2 am. Gained 20 lbs that semester.

Why the hell are there so many global warming alarmists today? "Oh no, if we don't stop now, it's fucking game over. We'll never get back to where we were before!". Fuck all of you.

You believe in science just long enough to believe climate change, but don't believe that science can also fix this.

>We have too much carbon dioxide in the atmosphere, it's all over!
Except for the fact that we can remove carbon dioxide from the atmosphere easily. The only thing is, there needs to be more funding to make this more viable as today it's prohibitively expensive (so was solar panels back in 1980, but today you can get one installed at home)

>The sea water is rising! It'll swallow up entire countries!
Today, due to pollution we're running out of fresh water. One of the ideas is using sea water. In the labs, technology exists today that can filter out the salt without needing to boil the water. Again, it's expensive as of today, but soon it might not me. The amount of sea water we'd need to give to drought stricken California would be enough that it in and of itself would be able to stem the rising sea levels.

>Species are dying off! We'll never see them again!
Store a diverse set of DNA and cell structures. One day when we're able to create cells from scratch, we'll just make one in that shape and throw the DNA in it. Then, through the magic of science, we'll be able to repopulate once lost species when we've saved the world.

>>7723278
Are you slow? The problem isn't that we don't know about these technologies, it's that most people don't care enough to fund them and actually make them viable on a large scale. That's why scientists are so vocal, because we need to develop these technologies but politicians want to keep most of our budget in fossil fuels and military.
>>
>>7723369
They don't though.
Even at the high level paris talks, all they were talking about was sustaining the Earth rather than fixing it.

We have the tech, but no one cares to use it. They just put plugs in their ears and go "la la la la la the world's gonna explode la la la la la can't fix it"

Why do we focus so much on Mars?

Shouldn't we be sending robots to Venus and other planetary-mass objects?
33 posts and 12 images submitted.

>>7722495
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 ?

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.
