From what I can tell by casual observation, maybe 10 to 20% of the population doesn't want to take the vaccine.

Yellowstone super volcano eruptions are rare and one is not predicted to happen in the next few thousand years. I read that smaller eruptions are more likely than bigger ones.
I suspect that in the event of a big eruption, the safest place to be (or head to) would be Florida. It might be safer to stay indoors. According to one site, the ash fallout in Indiana would be just a few millimeters, and extend down to the southern states like Georgia.
However, the ash contains silicates that can damage your lungs. You would want to have protective breathing gear.
A major eruption would severely damage the environment, causing crop failures worldwide.
There would be massive loss of life in the western states. The last major eruption, around 700,000 years ago, wiped out all the animal life in the neighboring states. The entire western half of the country would be in danger, as well as parts of Canada and Mexico.

All that shipping and freezing requires a level of technical sophistication that, for now at least, mostly exists in hospitals and labs—posing significant logistical challenges in rural areas and in the developing world. These are the "cold chain" problems that Koff mentioned, the problem of refrigerated shipping. (A critical Ebola vaccine needs the same deep freeze, and engineers stepped up to create specialized coolers to transport it across western Africa—but that was a pandemic that affected tens of thousands of people, not billions, and the people who made the coolers have since gotten out of the cold-chain innovation game.)

I love mathematics, physics and history. This is probably far more detail than most people would care about, because it might seem like useless trivia, but it lead to the discovery of physical properties that we didn't know about. No telling what we might discover next.

We don't even know if Dark Matter is matter. We just know that extra gravity exists that we can't explain. According to Einstein, gravity isn't so much of a force as it is a side effect of curved space-time. Even while we are still we are moving through space-time, and the curvature of space-time exerts a force on us. (Which to me sounds more like a cute mathematical model than reality.)
I wonder if the extra gravity could be related to the Higgs field or some as of yet undiscovered field?
Do Black Holes have Dark Matter in them? Do Neutron Stars have Dark Matter in them?

There is a small amount of evidence of cattle usage going back to 8,000 BC, but this didn't really get going until about 4,500 BC. During this period there were locally ruled cities along the entire length of the Nile. Eventually, there would be northern and southern kingdoms, which were untied by force in 3,100 BC, and this began the dynastic period of the Pharaohs.
Egypt was conquered by the Persians in 525 BC and conquered again by Alexander the Great in 332 BC. This continued till 30 BC when they were conquered by the Romans. Egypt began shifting to Christianity. During the late Roman period from the 4th to 6th centuries, they would be ruled by the Byzantine Empire, which had split from the Roman Empire. In 640 AD Egypt was conquered by the Muslims. It would be conquered by the Ottoman Empire in 1517 and conquered by the Napolean Bonaparte (the French) in 1798. Egypt was conquered by the British in 1882 and remained under their control until 1954 when the Egyptian Republic was established.
Egypt is one of the oldest examples of farming and human civilization.

I had a swamp cooler in my first house in Salt Lake City. It worked very poorly and my house would get unbearably hot, which is why I installed central air. I wouldn't dream of using a swamp cooler in my current home Indiana where the humidity is already at unpleasant levels.

"Methanol is not an acceptable ingredient for hand sanitizers," the FDA wrote. With use of hand sanitizers at a high amid the COVID-19 pandemic, the agency advised that anyone who has used the methanol-containing products "seek immediate treatment, which is critical for potential reversal of toxic effects of methanol poisoning."
The newly identified products are in addition to nine methanol-containing sanitizers the FDA identified last month, which are all made by the Mexico-based manufacturer Eskbiochem SA de CV.

Our understanding of the laws of physics is not complete enough to know for sure what will happen in the very far future. Maybe the universe will collapse and be reborn.

According to these scientists, who used 25 separate "parameters" or "variables" to describe every aspect of a bicycle's motion, there's no single reason for a bicycle's balance and stability. As they say:
"A simple explanation does not seem possible because the lean and steer are coupled by a combination of several effects including gyroscopic precession, lateral ground-reaction forces at the front wheel ground contact point trailing behind the steering axis, gravity and inertial reactions from the front assembly having center-of-mass off of the steer axis, and from effects associated with the moment of inertia matrix of the front assembly"
Or, in simple terms, it's partly to do with gyroscopic effects, partly to do with how the mass is distributed on the front wheel, and partly to do with how forces act on the front wheel as it spins. At least, I think that's what they said!'
I see a danger to the future existence of the human race, and it is the kind of thing that people should think about and prepare for now. Sometime in the next 50 years, machines will be smarter than people. There are major technical hurdles to overcome, such as the inevitable end of Moore's Law, which probably means that it is not right around the corner or even within the next couple of decades, but it will happen, and easily within this century. And if for some reason it does happen within the next couple of decades then that means the results will be upon us that much sooner.
We can predict what will happen next and follow it to its logical conclusion, which is a future without people.
As machines become smarter, people will become increasingly reliant on technology. We can see that already with smartphones, which only have been with us for barely over a decade. Eventually, machines will do all the heavy mental work, which will make our lives easier, but also make us more dependent.
And since we will be so dependent on the machines, we will start incorporating them into us. This will evolve over time until we are no longer purely human, but human-machine hybrids. Perhaps when your biological brain dies, the machine part of you will be able to continue with all your memories intact. Maybe it would have an artificial body or maybe it will exist in a virtual world. It is likely that some would prefer to live in a virtual world where they can do more things than they could in the real world. Taken to the eventual extreme, our descendants would no longer bother with biological bodies and prefer to exist as machine intelligence either in the real world or in virtual ones.
The evolutionary pressure will be against purely biological people. Having machines incorporated into you will make you more productive, competitive, and increase your quality of life.
The future I describe might be long distant, but if it is not the future we want for the human race then we should start thinking about it now. Maybe we could have a Pure Human movement that would prohibit the merging of machine intelligence with human intelligence? This could be roughly analogous to the current legal ban on human cloning, because we very likely have the technology right now to clone humans, but countries ban it because they are uneasy about the implications of where that might take us.
However, we might not be able to prevent it. Linking machines with human intelligence is likely to happen in such small steps that we will easily adjust to it. It is sort of happening already with our dependence on computers. It could also start as a series of military applications where having the most effective soldiers determines who wins wars. And once the genie is out of the bottle, we will never get it back in.

Sunspots go through a cycle roughly every 11 years where they alternate between no sunspots and intense sunspots. This affects temperatures on earth and can interfere with communications. There have been some really bad sunspot eruptions, like around 1860, where the electromagnetic interference damaged telegraph wires. If this were to happen again then we could see disruptions to the electrical grid and communications.
We did not know why this happens every 11 years but now we think that we do. The planets, Earth, Jupiter, and Venus align roughly every 11 years, and the combined effect creates gravitational tidal forces that interfere with the magnetic/electrical currents on the surface of the sun. The video gives more details.

Some of this ties in with conspiracy theories, which seem to me to be fueled by the belief that there are sinister forces that intend to do us harm.
A crude chess program in order to look 10 half moves ahead would take the hypothetical 25 moves possible and do roughly 25 to the 10nth power calculations, which would take a very long time. However, the alpha-beta algorithm eliminates mathematically unnecessary calculations making this more like 5 or 6 to the tenth power, which is a huge difference.
What surprises me is that program Stockfish reduces this to more like 2 to the N power, which is considerably less. Exactly how it does this I'm not sure, although I have some idea.
I would contend that looking deeper in chess will always involve an exponential increase, by definition. To not be exponential means that we could look infinitely far ahead and completely solve chess. This is kind of the point of the video.
This is interesting.
