How did it come to be that 140 (SD15) was made the "genius" IQ cut-off? Is it just something they arbitrarily generated when looking at the rarity and saying "yeah, that's good enough" or something?

Should be 130 given it's the same distance from average as legally retarded

Should be 150 since 100 is average and 50 is the gain from the "genius gene".

If I drink water with my food, how does my food still get digested when the stomach acid is diluted by the water? Checkmate, atheists.

>>9136604
The acid is diluted with the food itself, anyway. Your stomach calculates with that.

Drink bleach anon. Nothing to worry about since the acid counteracts it.
>>
>>9136604
The water is acid too.

Is liquid water scratch-able?

If not scratched, the water is certainly displaced by a scratching object and water can be used to clean or break softer elements at high speed.

So I wonder what this value would be on the mohs hardness scale, if above 0.

depends. is the water structured or not?

Lets talk about black holes again.

I have a problem for you:
There is nothing special about the event horizon for an observer passing through it, and with a large enough black hole the tidal forces from the extreme gravity wont be a problem here either. This seems to be the current consensus among physicist now.
You can also have an object in a stable orbit around the black hole that gets close to the event horizon. (The orbit gets very funky, but that doesn't matter.)

So lets say a man is orbiting this BH very closely and he stretches out his arm just so it dips into the event horizon, now clearly he cannot pull it back again, and even the blood and the signals from his nervous system couldn't come back.
Doesn't this directly go against an event horizon not being special to someone falling in?

Is there a known solution to this problem? Or am I just wrong about the scientific consensus somehow?

I have no idea where I should ask this so I figured I'd ask it here since this does involve some math. I've designed some rollers that I want to use to support a piece of pipe that is chain driven. Pic related. What would "optimal" spacing of these rollers be? Evenly spaced 45deg apart in relation to the center of the pipe? More? Less? Plz hlp anons

If the pipe is unsupported, that chain will be more slippery than your mom's holes upon my approach.

I'm not a mechanical engineer but I reckon it depends on the slack in your drive chain. You want your rollers as close as possible to minimize the radial stress, but at the same time, you want them far enough apart that the pipe is unlikely to escape. Theta is a function of alpha which is a function of the slack in your chain and how much risk you want to take.

The pipe is more likely to escape on the pull-side, so that roller might be higher.

do people actually break radicals into primes? i thought it was about factoring out more radicals. like you'd factor out the square root of 4.
2 posts and 1 images submitted.
>>
>>9136203
If you see a factor of a number that is a perfect square, then sure, remove it. But if you have something like sqrt (6*3*4*12) it might not be obvious unless you break into primes first.

Is there life on Enceladus and Europa? And how likely would it be to find life?

What's the point of finding life if it hasn't evolved into catgirls yet? You can just put some lichens on a space-rock if you want to find life there so badly.
>>
I don't think life can develop just from there being a presence of water. There's have to be other forces at play. Moons don't have cores, they don't have atmospheres, ruling out any serious form of electromagnetic inteference. I don't think it's very likely.

Doing some research for a book. How feasible would it be for a "mad scientist" to set up a lab somewhere without anybody noticing? He needs to do mostly genetic work, specifically sequencing and altering DNA. How much would it cost? If it was set up in a leased building instead of a house, what's the risk of getting caught? Whats the penalty if you do get caught? Pic unrelated.

>sequencing and altering DNA
This is not illegal.

If he's making some actually spooky stuff, like reviving old diseases, then he'll probably need around 2-10k EUR or USD. There was recently some research about how easy it actually is, since the genomes aren't secret and the tools are pretty much a commodity now.
I don't see why he'd need a lab, most of the equipment probably fits in a corner.
>>
>>9136128
Maybe a little over $1000 but it would be really crued and you'd still need to buy more supplies after each experiment.

Any brainlets on /sci/ who were bad at math/stats and turned it around? How did you do it? I seem to study forever, but when I get to answering a question, I just completely go blank.

There're various ways to increase intelligence. Image streaming aids in improving one's ability to synthesize information via strengthening the integration of various neurological spaces when thinking, which can bleed into analysis. Geniusintelligence.com also has a practice which boosts mathematical reasoning. It involves combining symbols and numbers in part of a mathematical addition sequence, but conditions the brain to think in terms of symbols = numbers, via representing numeracy in different formats. It's EXTREMELY effective at increasing computational speed, but like I said, facilitates the symbolically based computations of higher mathematics too

>I seem to study forever, but when I get to answering a question, I just completely go blank.
Supposing you really do study sufficiently, you just need to train yourself to stop and think. Every time you are presented with a problem, analyze the problem. Identify exactly what it is you are looking at before even putting pencil to paper. Closely examine every piece of information you are given until you understand exactly what is being asked. Even if you don't know the math, doing this can sometimes make it possible to come to a purely logical conclusion without any calculations even being necessary. Make an effort to understand the logic, rather than mindlessly plugging and chugging.

What are your scientific thoughts on Ecofeminism?
35 posts and 10 images submitted.

Due to the neurological disparities between men and women: Women are better at running societies, men are better at building them.

Being ecologically minded isn't purely a feminist trait.

Also egalitarianism's a superior nomenclature.
>>
>>9136040
Also espousing an ideology that women should run things is equally as oppressive and representative of a "logic of domination." Feminists trying to dominate men and the patriarchal society. Hypocrisy.
