- In a blind double slit experiment, particles go through two slits, which show up on a backboard in a wave form. However, the wave form is not physical, It's a probability distribution. Can anyone explain what a "probability distribution" in this case is, and what happened to the initial particles?

| Do carbonated drinks lose their fizz faster or slower depending on the altitude? Posted: 20 Jul 2017 07:37 AM PDT I just had a big move down to sea level from a much higher elevation, and I feel like my soda all goes flat much faster here, so I was wondering if Edit: People have guessed that it is also much hotter here in China than where I lived before (Northern USA). So even though the lower altitude should be preserving my fizz, the heat is kicking its butt. [link] [comments]  |
| What would happen if I started to rotate a 100,000km rod at 1 round per second? Posted: 20 Jul 2017 11:31 PM PDT Made out of the strongest lightest material possible. https://www.wolframalpha.com/input/?i=100000km+radius+circle The perimeter is larger than the speed of light per second.

| Why do some allergies only affect certain parts of the body? Posted: 20 Jul 2017 11:05 PM PDT Many allergies seem to only affect the respiratory system or the digestive tract. Why can the same allergen be rubbed on skin in some cases and no reaction occurs, or post stomach not cause reactions throughout the rest of the digestive systems? I am assuming there is no reaction after leaving the stomach due to the acid denaturing the protein responsible, but why is this the case for other parts of the skin/body? [link] [comments]  |

| Are atoms perfectly spherical? Posted: 20 Jul 2017 11:05 PM PDT I was thinking about how atoms are depicted as spheres, and were wondering how perfect they are? Thanks [link] [comments]  |

| Are there seasons on the moon or on the other planets in our solar system? Posted: 20 Jul 2017 05:38 PM PDT Is there autumn/winter/summer on the moon? How about on different planets? [link] [comments]  |
| How do you explain the photoelectric effect as a result of the wave function? Posted: 20 Jul 2017 08:25 PM PDT So in class, I've only been taught the photoelectric effect as a result of the particle nature of light. However, is there a way to describe it using QM tools like the wavefunction? [link] [comments]  |
| Posted: 21 Jul 2017 12:02 AM PDT Many primary sources list severe physical trauma that troops had from heavy shelling even miles away from the line. Any biological break down helps. Thanks. [link] [comments]  |

| If there's no ultimate frame of reference, how do we know the Universe's age? Posted: 20 Jul 2017 12:28 PM PDT Could some other civilization in a different galaxy measure CMBR and derive an age other than 13.7 billion years? [link] [comments]  |

| Posted: 20 Jul 2017 02:17 PM PDT A team of researchers in Mainz, Germany just measured the mass of a proton to a record new precision as 1.007276466583 AU. I was under the impression that 1 AU ≡ mass of one proton. How can you measure the mass of a proton in terms of itself and have that number not be 1? Furthermore, if AU is separate from the mass of a proton, then what is it? And how can we know what it is with more precision than they got for the mass of a proton? If we only knew what an AU was up to 60 decimal places for example, then wouldn't we only be able to know what a proton is to 60 decimal places just by how error works? [link] [comments]  |
| Posted: 20 Jul 2017 11:59 AM PDT Seeing as like speed is finite we arent able to see beyong 43 billion light years away. But if we know generally how fast the universe is expanding, is there a rough estimate to how far it extends to where we cant see? [link] [comments]  |
| Does the cosmic expansion of the universe change the universe's "flatness"? Posted: 20 Jul 2017 06:08 PM PDT Minute Physics released a video that explained that the amount of matter in the universe affects its shape (less matter makes space negatively curved and more matter makes it positively curved). Given that the universe is expanding, but new matter isn't popping into existence, does that mean that the universe will eventually become extremely curved? Follow up question: if it becomes more curved, does that mean that inevitably, space will eventually become so curved as so create points that become infinitely dense (as space curves in on itself?)

| Is there a finite amount of prime numbers? Posted: 20 Jul 2017 01:31 PM PDT I was watching a recent Numberphile video where they explained that formula can be used to calculate a gap of primes of any size. So taking that and using ∞ as x, wouldn't that mean that there is an infinitely long prime gap and couldn't be any primes after the gap, because the gap never ends? Thanks. EDIT: thats not an equation, it's a formula! [link] [comments]  |
| Posted: 20 Jul 2017 08:36 PM PDT Edit: Wish I could adjust title: Specifically what type of geography is this and how did it come to be? What are all these industrial sites near each of the ponds? https://www.google.com/maps/@61.5628831,72.9922958,11454m/data=!3m1!1e3 --this one includes a street view of some drilling machine? https://www.google.com/maps/@64.1883935,74.2266735,10016m/data=!3m1!1e3 --another example of the hundreds of industrial sites that dot the area: https://www.google.com/maps/@61.547417,72.732247,3a,15y,189.37h,93.65t/data=!3m6!1e1!3m4!1sQkLPkbJHCVCpm_cp7KuKsw!2e0!7i13312!8i6656 [link] [comments]  |
| Posted: 20 Jul 2017 11:44 AM PDT Am I misunderstanding the experiment? Like, what do they mean when they say "probability distribution"? That sounds just like math. Is the entire experiment just done via math, or with physical tiny bits of matter? Are particles actually hitting a backboard? What does it mean for particles to become a "probability distribution"? For some reason this is not making sense, but I may just be entirely missing something. [link] [comments]  |
| How will the world look in a few years, in terms of climate? Posted: 20 Jul 2017 11:24 AM PDT I don't mean things like "temperatures/sea levels will rise", since I already know that. I mean, if things continue as they are right now, how bad will the world be? How will it affect my life, basically? I'm scared for my future :( [link] [comments]  |
