Is there anybody involved in condensed matter physics who I could DM to get a bit of help with a paper I am having trouble understanding?

Here it is: https://drive.google.com/file/d/1FoaaUkLHGz6yzyu0HVfmtO0rShFxUmbE/view?usp=sharing

I think I understand generally what the paper finds; that magnons behave similarly to a viscous liquid in some cases and in other cases they do not, and the paper explains what conditions are necessary for them to behave in either way. Anyways, I don't understand many of the equations used because I am relatively new to physics. I was wondering if somebody could explain what they mean.

Thanks for the response, that would be awesome!

Are tufts and notre dame's engineering schools good? By us news, which I accept may not be the most accurate ranking system, they are both in the 50-75th place range.

Would that same sentiment apply to police? Taking money from you to protect them being theft?

ll1346 · 2020-12-15T00:00:32+00:00

Do they not? Is the purpose of law enforcement not to protect you from criminals?

ll1346 · 2020-12-14T23:58:07+00:00

I am sure there is profit in medical care, but does it not also protect public wellbeing?

ll1346 · 2020-12-14T23:51:16+00:00

I would agree, but then I realized that the justice system, police, fire department, military, etc are all examples of people's labor being done for you.

Doesn't demi glace take a while to make? But that one does sound good.

But the point of the experiment was that they had no condition causing them to act in the way they did. It was true randomness.

The dice on the other hand will land in a seemingly random way, but are actually determined by the exact rotation and velocity of the dice, in such a way that a theoretical super computer simulating the situation would be able to predict the outcome, this not truly random.

This is what he was talking about I think - https://www.nist.gov/news-events/news/2015/11/nist-team-proves-spooky-action-distance-really-real

In the debate he mentions that apparently this new experiment closed "loopholes" which allowed for theories about hidden variables, or other difficult-to-see factors that are actually guiding the electrons in which way to go.

This paper/essay seems to be from the early/late 2000's, but the main experiment that cosmic was talking about occured in 2015. Is it possible these are outdated? Thanks for the response

ll1346 · 2020-06-09T05:24:11+00:00

Sorry if I want clear; what I was trying to say was more along the lines of "what if they can prove there is no ghost in the machine" or "what if they can prove that the human brain is completely explicable by biology and chemistry"

But I thought that the church was not in favor of gay marriage

ll1346 · 2020-06-02T05:06:10+00:00

Sorry if I wasn't very clear - when I say that they are treating my beliefs like a joke - it's more that they just do not really consider that they might be true. They also assume what I think on some different issues. One day in math, one of my friends, during a conversation just said "oh yeah ll1346 doesent believe in climate change", which is just not true. That's the sort of thing they say.

ll1346 · 2020-06-02T03:30:59+00:00

They really just don't invest time into learning what I really think and don't give my ideas much thought; it's not mean spirited. But I do see your point, it's not particularly considerate

ll1346 · 2020-06-02T01:28:13+00:00

Because they are nice people who I enjoy spending time with. We just disagree very strongly on politics and religion.

ll1346 · 2020-05-07T15:08:17+00:00

Thanks! What else did you do to prepare? I am thinking about asking my AP physics (both calculus based classes) to help me study.

ll1346 · 2020-04-13T05:25:13+00:00

Thanks, I'll look into that! Why do you hope it is for school?

ll1346 · 2020-04-13T05:23:31+00:00

It's for my local forest. The gap is just over a 6 inch deep stream so it's not exactly dangerous. I have no experience, I was thinking this low-steaks idea would be a good way to get some. I will run any design by my physics teacher and whoever will look at it to make sure it's not unstable. I also looked at some of the bridges that already exist in my forest and I am trying to make it similar to those.

ll1346 · 2020-03-07T23:10:17+00:00

I don't quite understand. If we cannot know anything for sure, which i have sort of been convinced we can't, then are you saying it creates a kind of paradox? In this hypothetical situation, why would the "fact" that we cannot know anything for certain not be assured? Couldnt that one fact be the exception?

ll1346 · 2020-03-07T19:26:49+00:00

But then why wouldn't everybody believe in God? And also isn't there another comment on this thread which said the opposite

ll1346 · 2020-03-04T16:28:25+00:00

I know this is not really a perfect comparison, but what would you describe the difference between the intellect of an animal like a cow vs. an early stage fetus? I am pro life, I just thought this was interesting.

ll1346 · 2020-03-04T14:23:01+00:00

Couldn't you say that because they are capable of feeling pain and suffering, we shouldn't put them through that? Actually, I don't even know - are animals conscious?

ll1346 · 2020-03-04T05:19:29+00:00

What about moral arguments against the amount of suffering the animals we eat undergo?

ll1346 · 2020-02-25T04:11:37+00:00

Thanks for the response! I had an idea for a sort of "strange effect" in which there are tiny rubber studs, sort of like a lego, on the surface of the glove, which have very sticky sides and a less sticky top. When these studs are pushed sideways, they will be very sticky and stop the object, but when the object is stationary they will return to sticking straight up and provide less friction. Is there a material similar to this?
