This doesn't strike me as particularly accurate, I can't imagine where in the production cycle of a burger all that water comes in, and the site on the image has absolutely no information backing it up, other than vague graphs. Is this just how much water a cow drinks?

How are they arriving at these figures? My assumption is that they're fudging something somewhere.

>There's a limited natural supply of fresh water

No there isn't. It falls from the fucking sky. There might be a limit in the rate it falls, but effectively the supply is infinite. Also there is the quite obvious detail that the water that is drunk drink is breathed, sweated and pissed out again so it isn't like it is being removed from the system.

Which is exactly the limiting factor. If you use water faster than it falls from the sky, you've got a drought. We can speed up the water cycle with desalination, but it's a lot more expensive than water conservation.

>>4525

>The UK doesn't have a major water problem

Not yet, but there are some very real concerns about localised drought due to climate change. We've made big gains over recent years in reducing leakage, but we're approaching the point of diminishing returns. Thames Water already operate a desalination plant at Beckton; it's only used intermittently and processes brackish water, but it does indicate the relative insecurity of water supplies in the south east.

Well lets look at what you've actually claimed and go from there...

>The laughably incompetent assassins of the world's most nefarious security state (completely subverting our rather bloated GCHQ) - run simultaneously by a decentralised "Wild East" oligarchy and the iron will of that modern day Napoleon, Putin -

>The laughably incompetent assassins of the world's most nefarious security state (completely subverting our rather bloated GCHQ)

GCHQ is not omnipotent and this isn't a group of eskimo teenagers plotting a jihad on Facebook. The Russian agents understand how to use secure methods of communication. It would be like claiming that 9/11 couldn’t happen because the US air force exists.


>run simultaneously by a decentralised "Wild East" oligarchy and the iron will of that modern day Napoleon, Putin -

I'm not quite sure what you are trying to claim here, it is almost like you are trying to say the attack couldn't have happened because it is impossible for the Russian state to exist and operate even though it plainly does as we see it every day. Those 2 ideas are not as contradictory as you think that is basically how the Roman Empire operated for hundreds of years.

Suppose you have a cube of width x. Increase one dimension by dx and the volume will increase by (x^2)dx. Doing this on on all three dimensions will increase the volume by 3(x^2)dx. Integrate and we get x^3 as the formula for volume. Is this right?

More examples.

The surface area of a sphere is 4pi(r^2). An increase in radius by dr will increase the volume by 4pi(r^2)dr. Integrate and we get (4/3)pi(r^3) as the formula for volume.

The circumference of a circle is (2pi)r. Integrate and we get area = pi(r^2).

Am I doing it right?

The volume of the cross-section of an n-dimensional cone is kw^(n-1), where w is the width and k some constant. Integrate this over the length of the cone to give V = kAl/n where A is the volume of the base and l the length.

The case k=1, A=h, n=2 gives hl/2 as the area of a triangle.

Right?

Energy conservation only applies over small regions of constant spacetime.

So if we had the technology to manipulate spacetime we could create energy from nothing.

There are probably beings out there somewhere already doing this.

Conversation of momentum is space symmetry. Conservation of energy is time symmetry.

Because the universe is expanding space and time are not symmetrical and these things aren't conserved at the large scales. They are only approximately conserved over small regions of space and time like a small region of the Earth is approximately flat.

Bend a region of spacetime up enough in the right way and you can create or destroy any amount of energy or momentum you want.

4418 What are the waste products to this synthetic liquid fuel created from carb
Journal article here: https://www.cell.com/joule/fulltext/S2542-4351(18)30225-3

From what I understand, air is extracted from the atmosphere, the CO2 is separated and liquefied and turned into a fuel, to be used with hydrogen. This is supposedly, carbon neutral or "carbon-free energy". What are the waste products of using this as an energy source? Is it carbon neutral because no new carbon is being released into the atmosphere i.e. the only CO2 used is released back (net increase zero)?

The process is you take CO2 and crack it to form carbon monoxide, then you take hydrogen which is made from natural gas or from electrolysising water. The next part is called the Fischer–Tropsch process and we've been doing it industrially since the 1930s, you react the two together to make methanol which is the liquid fuel.

The downside is that you still need to put energy into it to get the fuel. So it's only carbon-neutral if you have a carbon-neutral energy source to put in. Recent developments have mainly focused on cheaper and more efficient ways to make the carbon monoxide.

Well, the CO2 that was released as a result of combusting the methane is the same CO2 that was captured from the air; when you burn wood the CO2 that is released was captured by the tree initially.

So why are computers so useful in the real world? The problems in the real world can't be random.

Is the universe is made of computational elements?

Or is it just that our computers are good at solving physical problems because they're made of the parts of the physical universe themselves?

Maybe computers in a different universe with different physics would be useful for solving problems in that universe.

Logically, what is a 'problem'? We can conceive of solving a problem as deciding whether a string belongs to a specified set of strings.

Solving the problem 'is 6 is even?' means deciding whether '6' belongs to the set {'0', '2', '4', '6', '8', ...}.

A computer program can be expressed as a string of text but not all strings are computer programs. So the set of all possible computer programs is smaller than the set of all possible strings.

By the power set rule, the set of all possible sets of strings is greater than the set of all possible strings.

Therefore, there are more problems than programs to solve them.

programs = strings

problems = sets of strings

That is like asking so why is a hammer so good at knocking nails in even if that type of nail was invented afterwards. The tool was designed for that purpose.

Up until recently we have used computers to solve a very specific set of problems that they have been designed specifically to solve (abstract maths and logic) things had to be broken down by someone who would explain things to the computer in the most basic of ways for really quite narrow use it is only that the work of hundreds of thousands of people has been colabrative that it seems like they are more than an input output box.

It has only really started getting a bit freaky since we developed evolutionary programing, but even a school boy understanding of dawinism should make it immediately apparent why that works not that that makes it's potential power less frightening.
