How'bout the fact that This isn't a girl?

Corn Flakes were invented to prevent victorian era children from masturbating, puely by being bland in taste.

I have not had a bowl of Corn Flakes since 1998.

When I was first taught about general relativity I found it hard to believe. I mean, come on, simply by being in low-gravity you age faster and time just general moves quicker?
But it's true, as it turns out. They have to reset the ATOMIC CLOCKS (super accurate clocks) on satellites every day, lest GPS be miles and miles off.

It could be so hard to believe because general relativity isnt true. At least certain aspects you have to use special relativity to get a sensible answer. If we ever get one theory that actually works for everything it may well be a whole lot easier to understnad.

Also, the actually US GPS system, I dont know about GLONASS, GNSS or future Galileo, Compass or IRNSS systems, but I suspect they are the same, you don't actually alter the clock on the satellites (I misspelt this as satalites and auto correct has suggest to me Australites, Natality, Satanism and Satanist.....Go go autocorrect...) they check them individually against known location ground station and then work out the time error based on the error in position, the satalite then as part of the ping it sends out of its position says "I have an error of this" which the handheld devices then compensate for.

Also, I'm fairly sure the standard theory for the loss of time is due to the speed they are travelling relative to the earth is that much greater and the closer you get to the speed of light the slower you age (Though this could just be the special theory of relativity). The actual loss of time per day for satellites is negligible but it does become significant over time. For one day however the inaccuracies generated by the bending of the signal path as it travels through the atmosphere is significantly greater. Compensating for this bending is one of the biggest problems in satellite navigation as the difference it can make is huge.

They don't lose time, the clocks actually SPEED UP when orbiting the Earth. Yeah, their high speeds will make their clocks slow down too, but the effect gravity has on time is much greater than the effect speed has on time.
When they first developed satellites they didn't believe simply being high up, away from stronger gravitational pull, would effect them. Within MINUTES the satellite was so far off GPS would mark you miles from your position. Granted, it's literally hundredth of a millisecond difference, but when you're trying to triangulate say, a phone out of anywhere on the whole EARTH, it makes the difference.

Pretty sure the satelites' time doesn't quite speed up. They are only fast in RELATION to us. Time for the satelite continues on at exactly a steady pace in the same manner it does for us. It is all about the relative relation between mass, time and position.

And thus, we have another victim who had a Bridget dropped on him. So, to help avoid such occurances again i have made up the following.

First Rule of Anime: Until proven otherwise, assume all characters are the opposite gender to how they appear..

I can't believe that someone made a thread complaining that someone said Portal was a bad game.

uhddh:
Pluto is a planet god damn it.

well given how many other objects are in our solar system just like pluto or larger and thus would be "planets" too you better start working on a new and very long mnemonic device to replace "My Very Excellent Mother Just Sent Us Nine Pizzas"

I Feel this is relevant.

That human beings are capable of treating words and categories as real and objective rather than immediately realizing they are mutable conventions for the transmission of concepts. Case in point: planet.

It meant thing that wandered because ancient people had no idea why they should move in odd orbits compared to the "fixed" stars. The definition changed over time. It will change in the future. Further discovery shall lead to new ideas of what objects orbit Sol and the other stars. In the meanwhile, Pluto will remain what it is in itself regardless of what we label it.

Schrödinger's Cat just seems impossible to me. Although I'm not sure if it's a fact or just a theory. (Although I have heard about those particles which behave differently when being observed, which just fucks my mind.)

JokerCrowe:

Think of the surface of a sphere. Every point is equally regarded as the center, and there is no edge.

In the fact, the boundary of any shape has no edges. Boundaries have no boundaries.

It was a thought experiment designed to show how crazy a particular view of quantum mechanics is, so the answer is neither fact nor theory. (Incidentally, theory means "a large model of reality which explains a lot of features, is well supported by evidence, and allows us to make predictions.") Schrodinger disagreed with Einstein and Co regarding what the new models of physics meant. He designed the thought experiment as a reductio ad absurdum - take the argument to its logical conclusion and show that it just doesn't make sense.

How particular physicists answer the question of "What happens to the cat?" basically tells you how their interpretation of the theory works. Some claim the cat is an observer, so the waveform collapses. Some say many worlds. Etc. Basically, how they handle this paradox explains how they interpret what the experimental results and equations of modern physics all mean.

That is totally a girl. It has to be. Or else in that universe, sex change operations appear almost literally perfect..

Also, snowfall in March. WTF!?

That there's a show targeted for 8 year old girls that's good. Well, I guess I accept it, but still. It's pretty shocking

Congratulations, that was actually the point of the Schrödinger's Cat thought experiment when it was proposed, to prove how ridiculous the idea of the wavefunction is by taking a sub-atomic system and linking it to a larger one we can easily observe.

Sadly, that doesn't mean that particles existing as wavefunction is false. In fact, Alpha and Beta radiation is proof of it, as it is not the particle that tunnels through the potential barrier of the electron "shells", but the wavefunction which extends beyond the barrier.

The way I've had to imagine it is that when a particle begins to act as a wavefunction, it basically stops existing. Instead, it becomes an abstract mathematical concept which, when squared, tells you the probability of the particle existing in any one place at any one time..... Looking back I'm not sure how much help that will be :P

Seeing as I'm doing a physics degree the maths does help alleviate a lot of the "wtf?!" you get from quantum mechanics.

What I refuse to believe is that the official scientific name for the numbers of nucleons that make up stable nuclei is "Magic Numbers". I'm not kidding you, there is a part of nuclear physics that requires magic. wtf?!

There is a planet somewhere in space made of Ice. This planet is also on fire.

I quite like to imagine God creating the universe and just going "Hey angels, lookit. This one will really screw with them."

...Now I want to photoshop a beard onto the trollface.

Can we shorten it to if lay public had any idea how freaking counter-intuitive and downright weird most advanced science was, they'd think it was all made up?

That people honestly think Super 8 is a good movie.

You've got my support. The mental cartwheels I have to do are proof enough of that!

I just can't get my head around the fact that some people, idiots you might say, take Yahtzee seriously.

Super position. How can something be in more than one place at the same time? And how does observation change where it is? Are the particles camera shy or something? I just can't wrap my head around it.

quantum mechanics are not for the sane to understand :P

also superposition is one word

Yes... Pretty much... I like quantum mechanics, because it throws common sense out the window, stomps on it, then spits in it's face.

Still, it's useful for taking the wind out of people that think everything about the way the world works should be obvious and simple...

One of the best quotes about quantum mechanics has to be this one though:

"If you think you understand quantum mechanics... You... Don't understand quantum mechanics."

Still, the logic of it is... Well, let's put it this way:

Normal logic:

This statement is true.
This statement is false.

A statement is either true or false. We may not be entirely sure which it is, but it is one or the other.

Quantum logic:

This statement is both true and false.

When we measure it, it will be one or the other. But until that point it will be all possible things at once.

In other words, quantum mechanics, if applied to the world at large implies something quite bizarre.

We tend to think things are false until proven otherwise.
Some of us may be inclined to think things can be true until proven otherwise, but even those people don't usually think contradictory statements can both be true.

Quantum mechanics implies not only that things can be true until proven otherwise, but that ALL options are literally true at the same time, even if they contradict.
That would be bad enough, but it then goes on to imply that if we try and find and answer, there will only be one correct answer.
But which one, depends on what we do while measuring it.

If that isn't enough to melt your brain, I don't know what is... (I mean, every possible answer is true at once, even contradictions... Yet at the same time only one answer is true if you measure it... Also, impossible things happen all the time, as long as they have a probability of happening greater than 0...)

Yeah, good luck getting that to make sense... Just as well that so far as we know it only applies to things at very small scales.
If day-to-day life worked that way... Ouch...

Quantum mechanics. As in, all of it. How can an electron be in one place, then be in another without going through the space in between? How can an atom's electron theoretically be located at the other side of the Universe? Why, if it's so happy to be everywhere else, does t refuse to be located at certain points? And so on...

Right, space is a 3D "edge" of 4D spacetime. A better term might be "slices", like the layers of an onion. Each point in time corresponds to on slice/layer of space.

People are talking about quantum superposition. But without interference of amplitudes like in the double slit experiment, there is nothing counter intuitive about quantum superposition. Flip a coin, and while it spins in the air it is neither heads or tails, then it becomes either heads or tails when you look at it.

The coin example shows that "existing in two states at the same time" is just bad language, we had a prejudiced way of describing the system (it's either heads or tails) and it breaks down because our description was too limited.

Now, coins flipping in mid-air do not exhibit quantum interference or entanglement (if they did we could use them to build a quantum computer!), so I'm not claiming that all the mysteries of quantum mechanics are this simple. But the Shrodinger's cat argument is really just about the superposition of possibilities, so unless we cause the alive/dead states to interfere with each other (classical probabilities can't interfere with each other, by interference I mean the technical notion of wave interference), then Shrodinger's cat is no more counter intuitive than a coin in midair that is neither heads or tails.

Eh. To be honest that's a fairly ambiguous drawing considering what men look like in anime.

Besides, being a drawing, it's quite possible to draw anything at all, then claim it's something else.

You want a real mindscrew, you need an actual, real person.

So... That being said...

Well, I love the whole quantum mechanics thing and also the whole 'there are different levels of infinity' thing (which I can kinda wrap my head around), but one fact which I frequently tell people that they don't believe is that the actual physical matter that exists in a human body can be compressed to the size of a grain of salt.

A true fact I have hard time believing is that artists went for 1000s of years before discovering how to paint and draw with 3D perspective.

rollerfox88:
That if the height of a single step on a flight is 2mm different to the rest, 80% of people will trip on it.

I cant bring myself to believe that we are that uncoordinated as a species...

Remember though, humans can't even sleep standing up. 2 legged locomotion is extremely unstable to begin with and walking for humans is really just a series of coordinated falls. Given that, I don't think it's too surprising that changing the required method of walking in an amount that humans can't really perceive would cause them to trip.

Also, fuck science. Pluto is a planet. I don't care about classification I just love the little guy :P

It's not walking it's falling in style?

OT:
People believe that the world is flat
People actually believe the Michael Jackson is dead, I mean come he obvious goes by Lady Gaga now
That the smallest level know particles is really made up of rubber ducks

Ah yes, 4D spacetime. I forgot about that. I guess the problem with the edge is that we intuitively understand it in the framework of 3 dimensional space, with an edge being 2 dimensional. Thanks for clearing that up, it makes a lot more sense now! ;)
