| How many distinct (linearly independent) fields are there in QFT? Posted: 09 Jun 2019 09:07 PM PDT My very basic understanding of QFT is that it describes all of physics in terms of fields, and particles are simply waves within these fields. So we not only have our basic fields like electric and magnetic, but also fields that describe the location and properties of electrons, quarks, etc. As such, the universe could, at least conceptually, be entirely described by the values of these fields at every point. The standard model describes all known particles, but I can't find anything that discusses the fields from which each particle arises. So my question is, how many of these fields are there, and of what types (scalar, vector (always 3 dimensional?), etc.)? In other words, how many distinct numbers would we need to fully describe all the properties of a single point in space. Bonus points if you can list all of these fields for me. Or if I have completely misunderstood QFT, please clarify. [link] [comments]  |
| How we know that how kreb cycle actually happens in the cell? Posted: 09 Jun 2019 03:47 PM PDT How do scientists study microscopic biochemical mechanism at cellular level like Na/K Pump, glycolysis, kreb cycle etc. In cycles products keep changing/converting so how do they keep a track of all of them? Considering they are so so minute and so so less in amount in comparison to average lab samples and experimentation. [link] [comments]  |

| Posted: 09 Jun 2019 08:58 AM PDT I get the science of how we see color via reflected light but I'm genuinely curious about how if an object is left in the sun for an extended period of time it will seemingly lose its color. How does it happen and what causes it? [link] [comments]  |
| Is Gibbs energy of activation same as Activation Energy? Posted: 09 Jun 2019 08:19 AM PDT I am solving a problem involving calculation of the activation energy of the reverse reaction and I've read that to calculate that, I need to add the change in Enthalpy of the reaction and the activation energy. In the problem, the Gibbs energy of activation was given instead of the activation energy. Thanks for the response! [link] [comments]  |
| Do two waves have to have the same frequency for interference to happen? Posted: 09 Jun 2019 04:08 PM PDT I can't find a clear answer to that. If i understood it right, fourier synthesis lets a bunch of waves with different frequencies interfere to model a complex one. So it should be possible for two waves with different frequencies to interfere, right? [link] [comments]  |
| Posted: 09 Jun 2019 08:18 AM PDT Edit: has been answered I know that in a vacuum a hammer and a feather fall at the same speed. On Earth everything regardless of mass falls with a certain acceleration speed A and on Mars everything falls with another acceleration speed B. I don't understand how this can be true regardless of mass, because it leads to different results depending on the perspective. What would happen if I dropped a feather and a hammer with the mass of Mars onto Earth? From the perspective of Earth you would expect them both to accelerate at speed A Okay, but what would happen if you dropped a feather and a hammer with the mass of Earth onto Mars? From the perspective of Mars you would expect them both to accelerate at speed B Mars-hammer onto Earth is the same scenario as earth-hammer onto Mars, but you get two different results depending on which side you are looking at it from.

| What makes a substance good neutron absorber? Posted: 09 Jun 2019 08:07 AM PDT Like many I too watched chernobyl on HBO and I was wondering what makes a noble gas like xenon a good neutron absorber? And how exactly does xenon stop the nuclear reaction in the core when it's concentration goes too high? [link] [comments]  |
| What exactly will happen when you swallow a piece of chewing gum? Posted: 09 Jun 2019 07:54 AM PDT What if i become lazy, so instead of finding a piece of paper to throw away my chewing gum, I just swallow it? Is there any consequences? [link] [comments]  |
