While there may be examples of what you are thinking of, I think the most common solution developed by evolution is invertebrates without an exoskeleton, meaning no skeletal structure at all.

Would you please elaborate on your question? What do you mean by an elastic skeletal system?

Can you give an example, even if fictional?

They were very careful in how they worded the request. They are not asking for people to change their voting behavior, only to create a plan, and to make some public statements.

Obviously, the latter part is fine but the voting plan doesn’t require that someone actually change their behavior. They are definitely skirting the line, but I’m sure they had the help of a lawyer when they made this.

I think you’re approach is generally correct, but you’ve made a few errors which make it hard to follow (e.g. mixing up suit and denomination).

However, method two is only more efficient if onky a few cards will be drawn. If nearly the entire deck is drawn or dealt, then 1 is superior. Method 1 can be done with two lists and a random number generator. The length of the 2 lists will always sum to 52 and the RNG is used to decide the order that cards are removed from the first list and added to the 2nd. It requires generating at most 51 random numbers.

Have you seen the Tom Scott video?

If it works for hamsters may be a properly built one could work for people, but there’s absolutely no ethical way to test that.

As an example, UW Madison which has a fairly large and profitable athletics program generated 12 million in profit last year. They aren’t the largest athletics program in the country, but it is bigger than many. Sits around the middle.

The patents and IP owned by the university provided $134 million in grants and support. Again, the school has a large STEM component, but it isn’t a top tier university. Again, sits around the middle. The organization providing this funding manages its investments carefully and intends to provide this level of funding year after year.

Research departments generated more revenue and the funding is likely more reliable.

As long as they do not interact with any other particles then yes.

Remember, in the photon’s frame of reference (i.e. It’s point of view), time does not progress. So it is created and destroyed in the same moment. Any distance traveled for any amount of time in our reference frame, happens instantaneously for the photon.

It belongs in a museum!

The video you linked summarizes the intent and benefit of Veritasium videos at about the 2:25 mark, stating that they are for a general audience. I agree that Veritasium isn’t perfect, and doesn’t provide complete depth, but they do a good job of creating interest in topics. So they accomplish their goal.

Additionally, the video you linked is wrong about the principles it discusses. The drift and diffusion velocity (group velocity) of electrons and holes is small compared to the speed of light. The relativistic effects discussed are caused by the phase velocity, which will be closer to the speed of light in the medium for even small currents.

Edit: originally, I incorrectly worded the last sentence which implied that the electrons and holes had a phase velocity equal to the speed of light. I hope the statement is more clear now, but I’m happy to provide additional clarification if necessary.

I think these are all excellent questions, but to my limited knowledge they haven’t been answered yet. I think these are all active areas of research in cosmology.

They are fun to wonder about though. If you have a deep interest maybe check out your library or bookstore. Once in a while scientists in these fields will write a book about their work in these areas.

Yes, that’s the one. Not exactly the same topic as the original question, but related.

It’s an interesting question, but a bit vague. Even at room temperature, relatively needs to be considered for the motion of electrons.

You’re probably thinking about bigger stuff though. The short answer is that temperature is unbounded so yes, there is a temp at which it is significant for the motion of all particles. I think inside of stars this can happen, but my knowledge jn that area is pretty limited.

Veritassium has a recent video about some of this that you may find interesting if you haven’t already seen it.

Thanks for the video. As it notes, the observations are real, but the explanation may not be known.

However, preventing the evaporation and then finding that the process does not occur kind of proves the evaporation theory, so I’m not sure that point works the way that you or Derek claim it does, unless I’m misunderstanding.

Lastly, I’m not claiming nor do I believe that there is some mystical way of violating the laws of thermo. I’m claiming that when the mass of water is reduced that the total latent heat is also reduced; that is completely consistent with thermo.

The reason the hot one freezes first is because the hot one evaporates more, thereby lowering it’s mass. The amount of energy that must be removed from water to cool it is small compared to the amount of energy to freeze the water. Therefore, the mass of the water that freezes determines the total energy much more strongly than the starting temperature.

Not by adding the hot water to the cold.

But if you can use the hot water to heat up the cold water a little bit, that can help. That would mean bringing them into thermal contact but not allowing them to mix.

Bonus question. What will freeze faster: a cup of 100 ml hot water or 100 ml cold water? Both are uncovered.

You can actually run your demonstration, literally in front of your own eyes, using a balloon and drawing some dots on it.

Anything with mass can’t travel at the speed of light, but a massless particle, such as a photon, completes its trip instantly from its perspective. A photon is created, departs, and arrives at its destination simultaneously.

I agree with nearly all of your points. The stopping problem is the same as the accelerating problem. Assuming near infinite energy reserves, but limited power generation, then the ship would accelerate for half the trip, turn around, and then decelerate for the 2nd half. Depending on the amount of power that can be generated, earth gravity may be possible during the trip (except for the turn around in the middle).

From some quick searches (so not a definitive answer, but a place to start), it seems that sound waves are most likely longitudinal which doesn’t cause shear. However, shear forces can be created by sound waves when they hit a surface.

From that information, I don’t think the shear energy imparted by a sound wave is very large. Since non-newtonian fluids only thicken under shear, they may not actually behave very differently than a regular fluid in these conditions. Preventing sound waves from traveling is usually accomplished by causing lots of scattering (open cell foam) or by absorbing the energy in a viscoelastic material (usually polymers).

It already has lost its meaning. Semites are anyone who speak or spoke a semetic language. Arabic and Hebrew are both semetic languages. Palestinians and Israelis are both semites.
