I don't know. Barely know how the game works myself. I played for two or three days several months ago. I always lost by a huge margin. Now all of a sudden I seem to have a shot at winning.

Although, I forget if the diagonals will change color if I place a chip on b1. I know the four white chips in the center of the first row will turn black, but that won't be enough to win.

Imagine a hypothetical alternate earth where there was no coal.

Could humans ever have invented things like current computers, the internet, and so on? Is there any alternate pathway of historical development that does not require coal, and achieves modern levels of technology?

Burning wood? There are very few things that coal can do which wood cannot, albeit at a lower efficiency and higher cost.

>>8136237
the Chinese were piping and burning natural gas for energy before Jesus was born, so I'd guess it's possible to skip the coal step.
>>
>>8136237
We have other fossil fuels right? Just no coal?

The US would not be the greatest country on Earth. Our success is largely because of our enormous coal deposits (there's a reason both sub periods of the Carboniferous are named after places in the US). But with other fossil fuels available we would simply rely on them more.

I saw a reddit AMA where Richard Dawkins was asked "what is the biggest mystery to science?" and he answered consciousness was.
What do we not understand about consciousness?
To me it seems like it is just simply the ability to reason?
22 posts and 3 images submitted.

>>8136065
Here is my thinking for this.
intelligence = ability to reason. with reason/logic being a limited thing (deduction upon reality, reality being limited) so too will the ability to apprehend this deduction
(intelligence) be limited.
hypothetically if a person we're to be absent all ability to reason, their mind being equatable to a sort of fathomless dream, are they
still an intelligent being?
no they are not. if define intelligence as ability to reason, without reason there cant be intelligence.
consciousness = an apprehension of reality
if they do not have the ability to reason they do not have the ability to apprehend.
therefore consciousness = ability to reason

Being so smart that you perceive actions before you're doing them. It's a rather ambiguous term as were not the only things living, just the only ones deciding to live. Not all decisions are conscious, so how are we to tell which part of our thinking is the conscious bit? There are of course levels of conciousness as in some people are infinitely less concious in their decision making. Most decisions have been social and cohabiting ones, even though they persisted from times we would not have considered ourselves as concious. Is relating to another's intelligence what simply defines consciousness, is IQ a measurement of that or is knowledge unconscious?

Just finished reading The Walking Whales: From Land to Water in Eight Million Years. It's a reasonably easy read and a comprehensive guide to what we know about the evolution of the whale. Do you guys know of any other books that provide a readable outline of the evolution of a clade?

Does it talk about that hip bone which has no current use? I've been interested in learning more about that.

Also interested.

While this isn't the same thing and it is fiction, but the book "Evolution" by Stephen Baxter follows humanities' evolution from tiny mouse-like creature to homo sapiens, to some other thing later on. It is actually pretty depressing.

Not enough to read it just for that. Really glosses over modern stuff and goes into each landmark fossil we have.

This man thinks that the insights of theoretical computer science are as deep and as important in the endeavour of understanding the universe as the ones of physics. According to him theoretical computer science is like physics with a bottom-up approach.

Does anyone know how to replicate a ln(x) function using simple math?

Doesn't need to give a similar result mathematically, but the graph should look similar.

Is the big chill taken very seriously in cosmological circles?

Because there's a huge problem with it. For the universe to keep expanding it needs more energy so infinite energy has to keep coming from somewhere so it can't ever run out of energy.

To put it simply, an object in motion stays in motion unless acted upon by an outside force. Ie. You can move something an infinite distance with a finite amount of energy. That being said, spacetime isn't actually expanding, so no energy is required. In fact, the lack of energy density is what is acclerating the expansion

I don't think so, the sails have to be massive to achieve a worthwhile amount of thrust, and that amount decreases as the solar sail vessel is pushed further away from Sol. You could use lasers to help push it along, but eventually you'll still run into the same problem. For example, if you wanted to take 40 tons to mars, you'd need a solar sail 2000 square meters across, and the trip would take almost two years. VASIMR thrusters could push you up to a faster speed and don't get weaker the further away they are from Sol.

Could work in conjunction with electrical thrusters for small light probes though.

no
solar sails are useless

Fusion is obviously the future, but until then fission would do just fine if anyone besides shitty Old Space government assets were spending money on it. Or if it ever got a "go" for actually being done.

http://www.bloomberg.com/news/articles/2016-06-07/china-pushes-plan-for-oceanic-space-station-in-south-china-sea

Reportedly the prototype/initial base will support 12 men. Then it will either be expanded or replaced so that it can support 33 men. It wil lbe nuclear powered and, contrary to earlier reports it will be a fixed seafloor habitat rather than a mobile submarine.

The official story is that the base is meant to facilitate deep sea mining. Aren't there cheaper ways to do this, like operating tethered robots from a boat? Could there be some other use for a structure of this type that they're not being open about?

I've no idea. I'd imagine there would be, but this might be more about some show of economic and technological might. A bit like the US did with the space race.

Eh, yes, ROVs might be simpler, but you could say that about space, too. This is a potential propaganda coup for them, rather than playing "space oneupsmanship" and trying to beat us to Mars, perhaps they hope to be the first to get people waaaay down there, instead.

What? No, the brain is the physical organ composed of neurons, and the mind is the result of the connections between neurons. That's like saying that a computer exists in the OS... The OS is that software that runs in the hardware of the computer.

Reality and perception is based in the brain and the brain is located in reality. Hmm
