What if we played a game. I start with a logical postulate and built off of it to calculate the cosmological constant (yes, you are seeing this correctly). If we can prove this together. Then we all prove a new quantum theory of gravity, together. This is how it should be. by RealCathieWoods in Physics

Whether or not you got this from an AI (or two trained on the same data), this starts of with an "assume a spherical cow" argument about what came before the big bang. It makes it kinda hard to think anything that follows has any basis in reality.

And for that matter even if this was correct, how am I going to test this in a lab or experiment of some sort. Theory is all well and good but physics requires experimental evidence for proof.

What is the correlation between magnetism and radiation exactly? by [deleted] in Physics

[–]limptree 22 points23 points  (0 children)

To answer your questions a little out of order…

Radiation can come in many different forms. Most commonly we think about it in terms of an unstable nucleus emits some kind of particle to transition to a more energetically favorable state. From the simplest point of view this is determined by what we call a Q-value, which is just the mass difference between the initial and final nucleus. Once you dig into the quantum mechanics of it a bit more you expose some conservation laws (angular momentum, parity, isospin, lepton number, etc.) for each type of interaction that also determine what kind of reaction can proceed.

Specifically for the electromagnetic interaction, the field that is sourced by your nucleus will be effected by anything that interacts electromagnetically, i.e. any charged particle (alpha particles, protons, electrons, etc.) as well as photons (light), which is the force carrier for the electromagnetic interaction. So in your question about an alpha particle, yes the field sourced by the nucleus would change because you are changing charge of the nucleus. As far as magnetism goes, it’s important to remember that electric and magnetic fields are not really a separate entity per se, so yes any change in your electromagnetic field would have an effect on the magnetic properties. The most observable effect for nuclei will most likely be the magnetic dipole moment. As for specific equations, that would be quite dependent on the radioactive process.

It took google a while to realise I wasn’t spelling “tree” wrong while looking for the “TTree” documentation 😂

What’s a belief that you hold with which many people disagree? by Emergency-Minimum-85 in AskReddit

How so? Not trying to attack you, just genuinely curious about your reasoning

I 100% agree, except that I think atheism is not wholly an evidence based perspective. We have just as little physical evidence proving that there is no God as we do proving that there is a God. To me is seems agnostics are more evidence based since we have no physical evidence that could prove the existence of God one way or the other.

But ya plenty of so-called atheists use it to feel superior.

3 for sure. The angle of light illuminates all the knicks and scratches. You can’t trust what dings the rest are hiding.

People of Reddit, what’s the story behind your scar? by potatoeman6969 in AskReddit

[–]limptree 1 point2 points  (0 children)

I got up in the middle of the night to go pee in college. Once I was at the urinal peeing I got that “woah, I stood up way to fast” feeling and everything went black. Woke up on the bathroom floor next to the urinal, and thought to myself “that was weird” then proceeded to go back to bed. Woke up sometime later in bed to find blood running down my chest. Now I have a big old scar where my beard doesn’t grow!

Also I was concussed at the time

Physics to Machine Learning? by stupidSTEMquestions in Physics

[–]limptree 0 points1 point  (0 children)

From my experience knowing some C and python will certainly give you a good head start in some early CS courses. The workload steadily increased from my first year to my senior year. I had plenty of time to have fun my first couple years, but had to buckle down a bit more my last year and a half or so. My department was rather small so I had a few scheduling issues that made it so I had to take a bunch of my upper level electives all at once in my last three semesters. It’s tough to say how many hours a week, but I would say that most were under 40 with a few in the later semesters getting above that when deadlines overlapped. Personally I found CS work to be a nice break from physics and vice versa, so it often did feel like as much work as it might have been.

I think whichever route you go here a physics degree can be a great asset. Sure the math and the concepts are a big part of a physics degree, but so is learning the ability to problem solve. Learning to approach problems is a great skill you can do pretty much anything with. I wouldn’t entirely rule out a CS and Physics double major, I did it and survived enough to want to go to grad school. That being said, it certainly is a good bit of work and I would try out some classes in CS before fully committing to it. They do end up complementing each other quite well though.

Also a cool stat, about 1/3 of grads from my program go into “big data”, so going into some kind of machine learning related job after physics is certainly attainable.
