We are bad at dealing with the chronic stress of working/commuting every day, having not enough sleep every day, seeing scary news every day etc. We are good at dealing with the acute stress of dangerous situations that last for minutes, not weeks, months and years.

The site tracks the movement of the mouse cursor when you are clicking that button, and there are specific ways in how humans move the mouse that can be analyzed and recognized.

There are people who are willing to risk their life or health just to put some graffiti in such a place. I mean there are people who would risk their lives for literally nothing at all, and in the graffiti case at least there’s a graffiti.

Worldwide, there are on average about three or four 5.0-5.9 magnitude earthquakes every single day. They are usually not destructive (or not very destructive) and don’t kill anyone. It’s just that these relatively small earthquakes are now getting reported in the media all the time because of the recent big one that was very destructive and killed a lot of people. And there is no wonder that a known seismically active zone keeps getting them.

Grocery stores know very well from experience how much food they are going to sell each day and plan accordingly. There isn’t much food going to waste really. The stores keep a lot of food on the shelves because it looks good that way (and is arguably convenient for the customers).

The fastest way to stop a car is to drive it into a wall. Also when you are braking with brakes you are already doing engine braking as well, since that takes place whenever you are in gear and not pressing on the accelerator.

Typical for Russians with a bar.

A hot object has fast molecules, i.e. molecules with high kinetic energy. When it touches a cool object (which has slow molecules), its fast molecules randomly whack into the slow ones and make them move faster, increasing their kinetic energy.

Those nutrients eventually get decomposed down to carbon dioxide and other simple compounds, which enter the oceanic circulation and get back up eventually, although it might take hundreds of years for a single atom of carbon to enter the atmosphere again. Sometimes the nutrients get buried by sediment before they can be completely decomposed, and then they become part of the tectonic plate and only get recycled in volcanoes (or not at all).

Both liquids and gases are fluids. That is the difference. Gas is a fluid, but not a liquid. All liquids are fluids, but not all fluids are liquids.

Other mammals, unlike humans, don’t even need to eat vitamin C at all.

In short, no, it varies. Most mammals can produce their own vitamin C, for example, so they don’t need to take it in with food. Humans (and other primates from the same group as humans, and also bats and guinea pigs) can’t make their own vitamin C, and therefore require to have it in their diet. In humans it’s due to a certain mutation that have broken our vitamin-C-making gene a long, long time ago.

It stayed to hibernate for winter in your house and woke up for whatever reason. You might have a nest somewhere inside, or in a place that connects to the inside. Or the nest is outside and it got in through an open door or window at some point.

Well it’s not 72,828 multiplications, it’s something like thirty multiplications. If 2838393 is N, you first need to calculate N^2 , then N^4 as the previous result squared, then N^8 as N^4 squared etc. and then just multiply some of those power-of-two results to combine them into the required final power. For example, if you wanted to calculate 3^9, you don’t need to make 9 multiplications. You calculate 3^2, 3^4 and 3^8 (three multiplications), and then multiply 3^8 by 3 to get 3^9 (fourth multiplication).

Modern computers can perform many millions of operations per second thanks to how tiny their components are. Computing isn’t a problem for computers, it’s what they do.

Because he was really good at what he did, and he had behind him a country with very motivated population that has just recently overthrown monarchy in a successful and popular revolution.

Millions of people experimented with food, many thousands got something interesting and passed down the technique of how precisely they did it. Exact measurements aren’t usually necessary if you manage to do the same things the same way as the original author.

Temperature effects of dissolving sugar (and table salt) are very small.

Gas molecules are light and fast molecules that can easily be bounced away and leave the liquid altogether. At low temperatures molecule speed is lower, so the gas molecules are less prone to do that.

No it’s not always like that. During dissolving the bonds between the pieces of the solid are broken but new bonds between water molecules and ions are formed. Breaking bonds requires energy, and making bonds releases energy. Therefore, if the pieces of solid are more inclined to bonding with water than with other pieces of the same solid, then overall energy is released and the temperature rises (e.g. sugar). Otherwise, energy is consumed and the temperature falls (e.g. table salt).

Dissolving is molecules of water hitting the solid particle and taking away pieces of it. Molecules of water are constantly moving around. Temperature is the measure of average molecule speed. So hot water has faster molecules. Faster molecules means that they hit the solid harder and more often. Therefore they dissolve it more quickly.

Water conducts electricity fairly well (due to the presence of dissolved ions in it). So from the point of view of electric current water is something it can run through. And since water tends to leak everywhere it is likely to be in contact with further conductors.

Yes, more or less that’s what is happening. The purpose is the formal declaration that the British government didn’t like something about what the Chinese government did, and they want the Chinese government to be fully aware of it. Other, more material steps might follow, or they might not. It depends.

Calculus has been developed over the course of two centuries, from about 1700 till about 1900. First the overall concept and useful results were discovered without a firm foundation, then people worked for a long time on refining the details. Nowadays it’s usually taught the other way round - from the basics like the definition of real numbers to the results like the derivative and the integral. But historically those things have been usefully employed with enormous success in math and physics much earlier than being defined in the modern way.

Because writing them over with zeroes or anything takes considerable time. Basically deleting files would then be as slow as copying them. That doesn’t apply to modern SSDs though, they do reset the memory taken up by deleted files.
