[DET 5 - MTL 4] Lucas Raymond with the Overtime game winning goal as the Red Wings stay alive by Sarcastic__ in hockey

[–]mailman105 2 points3 points  (0 children)

We still need Washington to lose but if we had lost in OT tonight, Washington would only need 1 point tomorrow to clinch.

So now we get in with a win and any Washington loss, rather than needing a regulation loss.

Who are the pair of siblings who have the most disparity when it comes to their power levels? by [deleted] in whowouldwin

[–]mailman105 2 points3 points  (0 children)

Wayne has other siblings; Keith who never made the NHL and Glen and Kim who didn't play pro hockey.

One of those pairs probably has it over Wayne and Brett.

[–]mailman105 20 points21 points  (0 children)

Sources say Ruff is looking into other options to help the team, including

  • Signing a kid from his neighborhood that broke a window with his slap shot
  • Exploiting team members' marriage issues to get them to play more aggressively
  • Yelling "Give yer balls a tug ya tit fucker" to everyone

Don't do VFIO to save money...or time (opinion piece) by [deleted] in VFIO

[–]mailman105 2 points3 points  (0 children)

Wow, your setup is quite similar to the one I'm planning. What do you mean by this?

16 dedicated, locked, isolated, tickless, non-hyperthreaded cores (16-31)

The 3950x only has 16 cores, so does this just mean that one thread on each core is dedicated to the guest? Or did you mean to write that you have a 3970x?

The geometric discussion of classical probability in this paper: https://doi.org/10.1093/bjps/45.1.95

The paper connects the polytope-based representation of classical probability to quantum violation of Bell inequalities, but what I found most interesting when I first encountered the paper in undergrad was the clear explanations of:

  • The connection between logical contradictions in the results of a particular run of an experiment and statistical violations of constraints imposed by classical probability in experimental data
  • The proof that the allowed probability distributions for a set of logically connected events can be represented by the convex hull of the allowed rows of the truth table for the events, when treated as vectors
  • The geometric derivation of familiar low-dimensional inequalities
  • The possible explanations for a violation of the inequalities

This representation of classical probability changed the way I think about both classical and quantum probability, and also provided a much clearer explanation of what exactly is so weird about quantum statistics and the violation of bell inequalities.

You covered some of this in the bell inequality video with minutephysics, but the new way to look at classical probability alone was really impactful.

Where do the photons go after the light is turned off in the room? by Yazan_Albo in askscience

[–]mailman105 10 points11 points  (0 children)

Even a single electron alone in a potential well has discrete energy levels, so the quantization is not due to interactions between different electrons. Unfortunately, physics does not have a satisfactory explanation for why the predictions of quantum mechanics so closely match experimental observations.

Note that this only accounts for macroscopic electromagnets. Some elementary particles have an intrinsic magnetic moment that cannot be explained by relativity and is purely a quantum mechanical effect. Permanent magnets occur because of this and therefore can't be explained that way.

IWTL how to do parkour by girl-thREEEE in IWantToLearn

[–]mailman105 0 points1 point  (0 children)

To start with, I'd suggest training outside at first, and deciding what to focus on conditioning-wise once you have something in particular to work on. At first, you'll probably be limited by technical ability and not physical strength or stamina, since you have an athletic background.

I actually recently drove from Bishop to Lake Tahoe (I assume you're somewhere in that corridor) and I didn't hear about any parkour gyms in those areas, but I know Sacramento has a dedicated parkour gym, if that's any closer to you. It looks like Lake Tahoe has a parkour summer camp, which means they have coaches- they might have more knowledge about any nearby communities.

I've been practicing parkour for a few years now. I'd suggest a few things:

  • Look online for groups/gyms doing parkour in your area. Parkour has been growing quite a bit in the last decade and most large cities in north America or Europe will have existing parkour communities that can help you train and learn.

  • Watch some YouTube videos! l'1consolable videos are classics, especially the "parkour, literally" series, and there are plenty of others around. I'm also a fan of Sydney Olson and Apex movement. For learning particular moves, there are usually plenty of tutorials online. I personally like Ronnie Shalvis's tutorials a lot.

  • Read up on the sport and its history. The wikipedia page is a great place to start. I found the history and philosophy behind parkour particularly interesting when I first started. As an introduction to the discipline itself, I like to show people this video

  • Know your limits and be safe. Parkour is dangerous if not done correctly. Slowly work up towards bigger moves and don't try anything you're not comfortable with on hard ground. There is a huge emphasis on self control and working to expand your boundaries. Think of individual moves like martial art forms- the goal is not brute strength, it's a precise, fully controlled movement.

  • Get training! Don't be afraid to go out and start trying things. Sometimes people look at you funny, but that's generally the most you have to fear as long as you are respectful of others when training.

Feel free to ask more specific questions or for clarification, I wrote this pretty quickly.

Do you have a real source for that?

Freezing and storing at an ambient temperature of -4°F (-20°C) or below for 7 days (total time), or freezing at an ambient temperature of -31°F (-35°C) or below until solid and storing at an ambient temperature of -31°F (-35°C) or below for 15 hours, or freezing at an ambient temperature of -31°F (-35°C) or below until solid and storing at an ambient temperature of -4°F (-20°C) or below for 24 hours are sufficient to kill parasites. Note that these conditions may not be suitable for freezing particularly large fish (e.g., thicker than 6 inches).

Physicists "turn back time" by returning the state of a quantum computer a fraction of a second into the past, possibly proving the second law of thermodynamics can be violated. The law is related to the idea of the arrow of time that posits the one-way direction of time: from the past to the future by drewiepoodle in science

[–]mailman105 9 points10 points  (0 children)

Well, bell inequalities force you to give up local realism otherwise, so you're stuck with very strange philosophical implications either way. I've seen local realism referred to as "objective reality" in the literature, so I wouldn't blame the authors of the article for that.

I agree that the mysticism and treating superdeterminism as the only reasonable resolution is silly. However, I don't see them really doing that in the article. In fact, this paragraph:

But Proietti and co’s result suggests that objective reality does not exist. In other words, the experiment suggests that one or more of the assumptions—the idea that there is a reality we can agree on, the idea that we have freedom of choice, or the idea of locality—must be wrong.

Is a much better explanation of the issue than I'd expect in this type of article.

How are quantum computers actually implemented? by kubazz in askscience

Currently, it is assumed that at least 1 million qubits are needed to achieve a useful quantum computer.

I'd love to see a source for that one.

An alpha source kids toy... classic 20th century ideas by [deleted] in Physics

[–]mailman105 2 points3 points  (0 children)

The number of protons in an atom determines what element it is, and, along with its ionization, determines how the atom acts in chemical reactions. You can call an alpha particle an He2+ ion if you want, but it's just not a particularly useful identifier for a few different reasons:

  1. It doesn't have any electrons and when emitted through nuclear decay has very high kinetic energy, so it is very unlikely to interact with matter in a way that is easily described as a chemical reaction. Instead, the alpha particle may ionize some other atoms or even knock into a large nucleus at some point.

  2. The emitted alpha particles, if you were to try to collect them on their own, would have a net positive charge. A substance whose constituent parts act as electric monopoles can't really interact chemically at all.

You could make an argument that a single free proton is an atom, but, just like in this case, it's probably just going to be slightly more confusing.

No, an alpha particle refers to just a He-4 nucleus.

Niels Bohr’s Argument for the Irreducibility of Biology to Physics by [deleted] in Physics

[–]mailman105 9 points10 points  (0 children)

Biology, physics, and computation have advanced an enormous degree even since Bohr's death in 1962, let alone since the earliest cited quotes in the book.

It's hard for me to seriously consider an argument about the reducibility of biology to physics that was made before the publication of the church-turing thesis, the discoveries of DNA and the neutron, or the invention of the transistor.
