You're completely wrong, but stars do have cores of heavier elements that are made during fusion and iron building up in the core of the star causes it to cool and larger stars to go supernova. The iron is said to be "poisoning" the star.

I'm trying to understand consciousness from a scientific perspective and I came across the qualia problem. Maybe I'm stupid, but I just can't think of a way how you'd explain to a blind man what the color blue looks like. Can /sci/ help?

You can't explain blue to a blind person

yeah. but why tho?

>> No.15778999

It's like saying "explaining to a brainless person what the color blue looks like"or "explaining to a nonexistant person what the color blue looks like"
His brain is simply missing the implimentation of the color blue. He hasn't seen the color blue, never even thought about it, hence the color blue does not exist for him.
It would make sense if humans for some reason had the capability to invoke and deactivate qualia at will or if our brains included a model of qualia itself so we could reverse engineer our own qualia and create new qualias on the spot. But we can't so that question makes no sense.

The brain does not know how it works.

>> No.15779004

it's weird, because if a blind person never visually experienced reality, and their brain just cannot build any kind of images and colors, that means that the qualia of red is transmitted (continually) by nature, in a way. and your brain "learns" of it at that point. if red does not exist in your mind in any way shape or form, it must exist outside it. it must come from somewhere, to you. which is still weird.

>> No.15779096

Red wouldn't exist if there wasn't at least one consciousness who experiences it. The qualium itself is not what's transmitted by nature, only the stimulus that evokes it in an observer. It doesn't exist immaterially (literally nothing does; if it did, thermodynamics would be violated), it exists only as instantiated in the physical substrates of minds that experience it

Why is everyone ignoring the elephant in the room. Aging.

Aging is the leading cause of death. Not only is it deadly but it's responsible for the systematic disintegration of your entire body and causes significant harm to an organism's quality of life. You might think..
>Oh I'm still young, let me not even think about it
But oh buster, as an adult it's happening to you. You might not notice it now if you're still young but soon you will start getting hit with the signs and effects of aging. It is the biggest existential threat your body faces.

So why isn't humanity focused on curing aging and finding the Fountain of Youth? Instead it seems people are busy arguing over petty bullshit when we should be figuring this out. The negative effects on quality of life because of aging happens at any age and happen in your 20s and younger even with some highschool kids balding. This isn't funny.

>Become adult
>Learn a lot
>Rinse and repeat
Bullshit I say. Imagine how much more advanced humanity would be with the average person having the wisdom and experience of a 200 year-old but the body of an 18 year-old. That would be sick.

Here's a thing to understand about immortality
It's actually the worst thing imaginable when you think real through.
There would be an inevitable point in life where you'll consider that would have lived enough experiences to satisfy your soul.
Now imagine you'll have to live the rest of eternity in complete boredom.
This is worse than anything you could imagine.
Now that obviously doesn't mean we shouldn't stop research in reversing aging.
A slowly decaying flesh prison isn't fun after all.
We will allow people to live fulfilling healthy lives until the day they consider they have lived enough.

The question is:
>given the boundary conditions as shown in the figure (red box enclosed because 'tism) find temperatures at T1, T2, T3, and T4
basically, two sides of the plate are at 100 Celsius and two sides are at 200 Celsius, and you have to find the temperature at 4 points in the middle

Just solve heat equation numerically. Pretty easy to do in python. It meant use a python library to solve DE. I would've done it but it's night and I'm in bed trying to get some sleep.

>> No.15778861

I can't tell if it's supposed to be like a plate of metal with lines drawn on it, or just the grid shown. I guess you've tried to solve for the grid shown, but I think you've got it wrong. There is a symmetry, which shows that T2 and T3 should be 150 (for either problem), in which case, T1 would be 125 and T4 would be 175. I think your initial equations are right, and I don't think your solution satisfies them.

In the case that it's really a 2d plate with boundary conditions along the edges, you are actually solving Laplace's equation, which is the time-invarianct version of the heat equation. It's not hard to solve numerically using a fine grid and solving a big linear equation. Analytically, the solution will be the real part of some complex analytic function, which I don't recognise. Near the TR and BL corner, the solution will approximately depend linearly on the angle from the corner.

Not any great difference. He merely added CCR5 to the gene mix. Immunity to HIV and a minor learning improvment is all it affects. Nothing notable.

Did you meant the CCR5 modification or in general? Because I understood that you asked for the purpose behind gene editing in general.
While no chimerification is known such modifications still need rigorious testing before such method can be implemented for medical praxis and then there will still be some resistance from conserative and preservationist groups.

Is it possible that the media is innacurately reporting an increase in droughts as the fault of climate change, whereas the true cause of an increase in droughts is due to increased demand.
Demand in 3rd world countries has increased immensely. For example, Pakistan's population in 1950 was 40 million, now it is 220 million. Without any chance in flood patterns of volume, the number of people exposed to flooding has increased.
The media then might state "the number of pakis exposed to flooding has increased five fold since 1950", and then in the article go on to talk about some unrelated aspect of climate change. Both statements would be factual, but deliberately misleading.

Try looking at the graph again. You will see how the supply though highly variable has no particular trend. Notice how demand starts well below the supply of water, and steadily increases until it surpasses the supply of water.
The demand then drops around the year 2000, but remains above the supply.

During this time where demand outstrips supply, the media will bitterly complain of droughts, how the cause of these conditions are climate change, and not simply an increased usage of water.

Electricity and energy aren't electrons, it is not movement of electrons, it is **movement** that carries particles or make them move, to be useful, this energy has to be 'converted' but esentially an action that makes/forces a particle to change its position in space is energy..
