What is this miracle device?

Payback says...

Enlightenment, or, "DUDE! IT'S DOING IT TO YOU AS WELL!!!"

I felt sad when I found out non-euclidean geometry was only theoretical too.

And that moment of enlightenment when he sees the dude in red *also* has a twin on the other side of the portal !

Vi Hart - Why Every Proof that .999... = 1 is Wrong

Wormholes & Portal 2 - Sixty Symbols

GeeSussFreeK says...

Imagine a universe that lasts of only 10 seconds and only has one particle in it. Lets call the end of time X. At X - .99999999999999999999999, we send the particle back to T = 1. At T= 1, we now have 2 particles. At T = 1, we send both particles back to X - .99999999999999999999999. We do this again, and again until we create a universe of infinite density from one particle. I don't know if this is exactly the time of feedback they are talking about, it is from my own thought experiment on time travel.

The whole feedback thing was really interesting though, the reason we can see through the portals is because light radiation is streaming through the portal to our eyes. If you stuck a portal infront of you and then a portal behind you, light radiation would stream in and out of the portals into an infinite feedback loop causing catastrophic energy output.

Why would that happen? You're not creating more sources. It would be the same net effect as pointing two mirrors at each other. Only instead of light bouncing off and heading back, the light stops being in front, and then appears behind.
Light passing through recursive portals would end up collimated, but I can't see how it would multiply, as the light coming out of portal a is disappearing into portal b at the same rate.
Personally, I was kinda let down that the portal system didn't really change, they just added magic goo. I was TOTALLY expecting PortalGun 2.0 to create bi-directional portals, that is, you would exit one side or the other of portal b, depending on what side you entered portal a. True non-euclidean physics. Also, did Valve ever describe the portals as worm holes? I always thought they were quantum teleporters or something to do with nth dimension physics.

Illusion - The Impossible Puzzle

GenjiKilpatrick says...

Dan Secrest - The reason why there is a gap in these "triangles" is actually related to fibonacci's sequence. But I wont go there. The easy solution is simply because those are not triangles. Each has 4 sides. The red triangle has a different slope than the green. The red triangle has slope 3/8 while the green has 2/5. Therefore, in the upper "triangle" there is increasing slope along the hypoteneus and in the lower there is decreasing. The short short answer is that the areas of both triangles are EXACTLY the same, but the lower triangle has a gap to make up for the different slope it has on the hypoteneus. If anything, these resemble non-euclidean triangles because there angles add up to over 180 degrees.>> ^dannym3141:

Notice how easily the pieces slip into place in the first layout compared to how he has to force them into place on the second layout.

>> ^MINK:
according to the survey, 6/10 people believe the new ideas that everything can be rationally understood.
"evolution is the explanation for our existence"
HOW? explain to me how evolution is the explanation for our existence you pompous twat. I watched loads of your videos and all you can prove is that we evolved. From WHAT motherfucker?


Abiogenesis ?

Are you talking about the formation of amino acids and proteins from inert base gases with an electric catalyst ?

Evolution is the process by which something very very simple, undergoes natural selection, and evolves into something complex. Its been shown in the lab time and time again, without evolution we wouldn't need AIDS medication, nor anti-biotics, as germs wouldn't evolve...but alas, they do.

We've also shown in lab environments that we can create life from non-life materials.

We can also see through Doppler principle and phase shift of the stars, that literally everything in the universe originated in a single point, about 14 billion years ago.

We can also model accurately with the laws of physics, the evolution of the universe, which eventually unfolds basic hydrogen and helium into the more complex, heavier elements. We can also show how solar systems, stars, planets, moons etc. can form.

Its truly amazing what hydrogen can do given 14 billion years.

If you cant wrap your head around it, don't presume its false. I cant wrap my head around non-euclidean geometry, that doesn't mean I'm about to run around claiming that its a load of crap, and the relativists out there are all in it for the grant money.....the scientific method ensures that theories (the highest scientific standing of any hypothesis), are the best model of our understanding of how stuff works.

In science, the word "fact" does not exist. It ranges from guesstimate, to theory, with theory being as close to the laymen understanding of fact as you can get.

Reaching your intellectual limitations and claiming that something beyond your understanding is false, is supremely arrogant.

Evolution is the framework for which the natural selection mechanism allows simple life to become complex and adapt, and it most certainly not a random process. Think of it similar to a binary accumulation search algorithm.

Im thinking of a number between 1 and 100, each guess I will tell you if you are higher or lower. The binary search dictates you guess in the middle each time, it should only take 7 guesses max to reach the number (if its less than 128). This is very similar to evolution via natural selection.

Lets try this gene...is it better or worse than its pre-decessor ?

If better - propogate it, else, kill it. Very very simple.
