Quantum physics is so ******* wizard, seriously, I'm only one year into an advanced physics course, so I know next to nothing on it, but quantum tunneling? Holy **** , it's literal magic. Quantum entanglement? Quantum spoopiness? **** . You could make so many people interested in physics and make a ******** tonne of money if there was a cosmos style tv show on the basic crazy things.

******* science man.

The general public won't understand even the most basic scientific principles.
I find the notion that they would get quantum mechanics or there could be huge amounts of profit to be made from a tv show about it naive.

You'd soon learn that alot of wizardry is explain with alot of complex math. Physics itself is not that hard; it's drawing a parallel from the math you're doing to the physical world that is hard; at least in my opinion.

Also, the thing in quantum mechanics I've found the most strange and counter-intuitive is the uncertainty principle for energy and time. Basically, a particle can borrow any amount of energy, seemingly out of nowhere, as long as it's for a short enough time, and it afterwards returns the entire energy to... whatever it borrowed it from.

I doubt that you study physics if you think quantum mechanic is wizardry. It got a lot of counter intuitive results but that's only because we're used to a scale where quantum effects are negligible, but it's all pretty rationnal. It's just that reality is probabilistic and non-local.

"pretty rational" is an overstatement. There's alot of new math and ways of thinking and rational and intuitive are the two words I would never use to describe it.
.. and the word "negligible" bothers me in that context.. Quantum effects simply does not happen on larger scales. It's not that it's too small variations so we can't see them, it literally does not happen on any small un-isolated particles.

How about the many worlds interpretation? Doesn't it state that a possible explanation for quantum effects only happening observably on smaller scales because when it happens on bigger scales it literally creates parallel universes?

I only know about quantum physics on a hobby level, please don't kill me if that's wrong.

kinda and not really.
Quantum effects don't happen on larger scales because for quantum effects requires a certain level of uncertainty or "unknowsness". The particle in question must be unobserved to be in that quantum state called a superposition where it is both a particle and a wave-form at the same time (particle-wave duality). If we know the, say, position of a particle at any given time, we've measured the superposition and it collapses to a particle and only a particle. We can't measure the position of wave-formation, so of course it's a particle. If you drop a pebble in water, exactly where is the waterwave?
[sidenote: Quantum effects have been successfully tested on larger scales as well, up to molecules of ~100 atoms if I'm remembering correctly. Just requires the right setup. ]

What your saying about the multi-verse theory (or many worlds interpretation) is a currently valid theory, and one I myself hope and believe to be true, but it doesn't explain why it quantum effects don't happen on larger scales. It, like you correctly say, states that every time a particle has to choose from a superposition, it creates two new universes, one with each outcome of the superposition. This however, is really really hard (if not impossible) to prove and will probably remain a theory for(ever) a long time.

\rant sorry

I'm a writer with a predisposition towards science biology is my speciality though , give me a shortlist of stuff you've found particularly wizard and maybe we can talk about this " ******** tonne of money".

I also appreciate your use of the metric system to describe the cash influx

Young's slit experiment is cray-cray
Quantum computers are cray-cray
Quantum tunneling and entanglement as previously stated are ******* looney toons
Three things that aren't quantum physics but that I love even more are room-temperature superconductors, nuclear fusion and thorium based nuclear reactors.

I can't wait until governments get their act together and start funding more research into these world changing and mind blowing things (Room temp superconductors even with limited funding are expected to be here in 10 years, fookin hyped) . Science is so much fun, and I'm really just in the shallow end, I've got so much science to come in my next 4-5 years of education, and I truly believe that we're entering a singularity of science in the immediate future.

Eliteangerous, it's a game where the entire map's one whole galaxy

Couldn't agree more. In my field we're getting close to synthetic DNA, a true understanding of epigenetics, negligible senescence (read: immortality), and maybe even genetic programming. By the time we've reached the limit of human understanding I truly believe we'll be able to move the goalposts.

I'm vaguely informed about fission, superconducters, and thorium reactors (why are we not funding this?) but my quantum physics is a little below par. Would you mind giving me the cliff notes on the three things you mentioned?

I've always found enthusiasm gives the best explanations.

Seeing as he doesn't I'll try.

Young's slit (never heard it by that name) or the double-slit experiment : Pictures a bolwing ally where someone blocking the lane at the halfwaypoint with two slits. If you throw a bowling ball you'd expect it to go through either one and end up in a similar pattern down the line where the pins are. ( cs-exhibitions.uni-klu.ac.at/uploads/pics/doubleslitexperiment.GIF first picture )
What we instead see is that the particles are actually waves interference so a wave pattern emerges on the back of the bolwing ally ( cs-exhibitions.uni-klu.ac.at/uploads/pics/doubleslitexperiment.GIF second picture )

Quantum computers: I've not studiet this in depth so I think these guys gives a better answer. Also, watch this and everything else they've made. They're geniuses: www.youtube.com/watch?v=JhHMJCUmq28

In quantum physics everything's a probability. quantum tunneling is where a particle has a low energi, but via. this probability, it can "tunnel" through a potential bigger than it's energy, without breaking the laws of physics. Image a ball getting outside of a bowl without anything pushing or lifting on the ball.

Quantum entanglement is really weird and something physicist still struggle to understand and is focus in many experiments. Basically, two particle can be linked and transfer information between them faster than the speed of light (breaks basic physical laws)
The last answer is somewhat wrong, but for simplicity, I won't go into further details, as that would take my whole afternoon ._.

Hope that wasn't too ******** written or to confusing to read.

Thanks for the cliffnotes, although I confess to not seeing the significance of the double-slit experiment. I may have just had an idea or two.

Do u have a sauce on that gif? it looks like elite dangerous but im not sure
User avatar #88 to #32 - reeeeeeeeeee (01/09/2016) [-]
Yeah it is
#18 to #15 - derangedbear (01/08/2016) [-]
yeah, but some people who get interested in physics by seeing the highlights you'd see from tv shows and pop-sci. Nobody talks about ******* depressing and excruciating it is to get through the whole degree. It's a whole 'nother ball game compared to what you see on television.

Nice architects pic btw.

Ta for the notice. And it is a shame that not everyone can like physics to the same extent, it's really only in the last couple of months that I've begun to like it a lot and I'm glad I have
