when you put ur hand near something cold as to feel the cold. are you really just feeling the gradient of heat moving in that direction away from you?

>>9146908
yes. humans cannot actually sense temperature, merely heat transfer. its the basis of the "REEL FEEL" temperature they show you on the news.
>>
>>9146908
Yes. Though I do recall one entrepreneur trying to sell "cold focusing" mirrors some time back.

Reifying "cold" is a common human misconception.

Consciousness and electricity seem to be correlated. There are many cases of people who lost their consciousness in accidents (died), but when a conductive material was stuck in their heads, they regained consciousness, and when it was removed shortly after, they "died" again, and you literally could turn them on and off by sticking that metal shank in and out their heads. And if you do look into it, there are many cases showing electric shocks improve people's mathematical capabilities.

So I would like to share an hypothesis. I think consciousness arises from electricity. To be precise, there must be a very large circuit system with any number of components. The smallest possible circuit makes a binary consciousness, on and off, either 1 or 0, but it becomes more familiar to our concept of sentience when you get to the order of tens of billions of components. However, this would only be a temporary form of consciousness. For that to be more like our consciousness, large parts of the whole circuit would be arranged to store memory - the past - and make calculations and predictions - the future -. Note that, therefore, the number of components can make a gigantic circuit have as much consciousness as a light bulb's circuit if things are not arranged in the right way.

I would like to know what you think about this. I wonder if there's a way to test this hypothesis. And if a dumbass like me thought of this I imagine actual scientists must also have thought of this, so are there any papers on this subject?

I think its bullshit for an extremely specific, basic reason.

There is no reason why a particular configuration of electrons should have a subjective experience. Even when people call it an 'illusion', something has to be experiencing that illusion. Then, consciousness can in no way be explained by our current laws of physics - there's no causal connection between the four basic forces and there being subjective experience.

Then, I believe consciousness is an inherent aspect of the universe and exists in a kind of field, similar to mass or gravity, and that specific configurations of matter produce organizations of consciousness which have the behavior of having a feeling of 'self-ness', i.e, our brains. Then, while the entire universe would then be collectively conscious, only particular configurations of matter would have the sensation of being limited to a body or being a single self.
>>
>>9146828
No there isn't. I dont think any scientist would say consciousness was the product of a single thing like electricity.
>>
>>9146828
I.e. I don't think there's a unit of consciousness. It emerges. I think the only bit i would agree on was on arrangements for prediction, memory etc.

Let's say you're doing some pretty basic trig subs, you go through the integral and then convert it back to being in terms of the original variable, introducing maybe a few inverse trig funcs. Done. Or so you thought. Unfortunately you realize that that pesky arctan or arcsec or sqrt you end up with introduces a sign error when x is negative.
Any good tips to avoiding this?

Yes, I have a solution for this. It is a simple method: change your major from pleb engineer to masterrace mathematician.

There calc is only for its symbolic value. In ODEs not once have I even put the absolute value inside the logarithm when integrating 1/x. I just don't give a fuck. It doesn't matter. We only care about the substitutions and qualitative aspects of solutions because we will never actually apply the solutions we find.

I was thinking this graphic is misleading because it shows the height of the explosion and explosions are about volume.

I wanted to know how the diameter of a Tsar Bomba blast would compare with the Hiroshima blast.

So.. a sphere is (4pi/3) * r^3. Let's suppose the volume/power of the Hiroshima blast is 1. then 1 Hiroshima Blast Volume = (4pi/3) * r^3. Solving for r we get ((3/(4pi)) ^ (1/3) = r = 0.62035049089 (units of length I hope?)

Tsar Bomba at 5000kt was 333.3 times as powerful as the 15kt Hiroshima blast.

5000 Hiroshima Blast Volumes = (4pi/3) * r^3
So r = ((3 * (5000/15)/(4pi))^(1/3) = 4.30112668869 ( are these Hiroshima blast radii? What units? )

((4 * pi) / 3 ) * (4.30112668869)^(1/3) = 6.81212624003 ( of what?) I thought Tsar Bomba was supposed to be 333.3 times Hiroshima..

What about if we assumed explosions were cubes? Then the formula for volume is l^3.

1 Hiroshima blast volume = 1 Hiroshima blast length ^ 3

1 Hiroshima blast volume ^ (1/3) = 1 Hiroshima Blast Length.

1 Tsar Bomba Blast Volume = 1 Tsar Bomba Blast length ^ 3

5000 Hiroshima Blast Volumes = 1 Tsar Bomba Blast Length ^ 3

((5000/15) Hiroshima Blast Volumes) ^ (1/3) = 1 Tsar Bomba Blast Length = 6.93 (units = Hiroshima blast lengths?)

I feel like I am fumbling around like an idiot.
(1000/15) Hiroshima Blast Volumes ^ (1/3) = 1 Mike Blast Length = 4.05 ( units = hiroshima blast lengths?)

er, that graph has nothing to do with volume or size, except referencing how much energy is released in kt (and mt) of TNT
>>
>>9146696
It's drawing a mushroom cloud shaped thing as tall as the energy difference is. But I would assume the volume of the explosion would be proportional to the power. And volume increases as the cube, so the cloud of Tsar Bomba would be much smaller than shown here relative to Hiroshima.

But then I started trying to calculate how tall Tsar Bomba should have been drawn to look right and realized I generally suck at this sort of thing...
>>
>>9146715
just dont assume things based on the graphic, it's just a cute picture but doesnt really hold any data other than the tip of the mushroom cloud being the data point. I really doubt like "destructive power" is directly proportional like that. But yea i can't help with the calculations sorry

What actually IS the best framework of racial anthropology?
Coon's racial types get used in a lot of literature on the subject until around 1970, when all of a sudden people stop talking about him, but I can't find anything to actually refute his research, just accusations that he was a racist/segregationist.

Not really, although it does have the issue of not having any modern capability to be experimentally tested. Because of that, it's stuck in a state whereas it makes sense and adds up in theory but no one really knows for sure if it is true

I think i have discovered a theoretical way of cloning. Im not bullshitting. Everyone knows how identical twins are made, the egg is fertilized and splits into two and two foetus' develop into twins. Well that is the whole principal of the theory. If science can find a way to perfect the splitting of the fertilized cells and have a good success rate, then /sci/ may have unlocked cloning.

>>9146535
This has already been done. You can pay an IVF company to do that. It's not "cloning" per se because cloning implies that you are making a copy of something already born.

A friend of mine told me once in passing that if you could collect all of the energy emitted by a black hole with the mass of 40 billion suns through hawking radiation,across its entire unfathomably vat surface area, and concentrate it together, it wouldn't even be able to power a nightlight. Is that true?

Hey /sci/, italianfag shitting myself out.
Tomorrow I'll leave my country to follow an applied mathematics Msc programme of 90 CFU.
I have no idea on how the English university system works, but for what I have seen it's two semesters of hell, with few lectures and lots to study on your own.
Now I am scared as shit: in your system what happens if you fail an exam? Do you have the chance of repeat the exam in the same semester or you loose the whole year?
