The basic solution to the paradox is integral calculus. The normal statement of the paradox keeps using smaller and smaller time intervals. Integral calculus lets you take an infinite number of infinitely small areas and have it add up to a finite answer. (Which is scary at first, but you get used to it pretty quick.) Once you have that insight, the paradox goes away and the normal view of velocity versus time gets strengthened.

It depends on how fast money is created versus how fast the growth in goods and services is. If goods and services grow faster than the money supply grows, then prices decline over time. This is really painful to people who have borrowed money and have to do more work to pay it off. If the money supply grows at the same rate that goods and services grow then prices are stable. If the money supply grows faster, we have inflation which we are currently experiencing. If the FED can rein the US money supply growth back to levels closer to the growth in goods and services, then it can go on indefinitely.

Yellow is a primary color in the subtractive system. This is the ones that paint and printing use where the ink or paint subtracts some of the white light. TVs and monitors used the additive system where the three primary colors are Red, Green and Blue. You mix Red and Green to get yellow.

The tilt of the Earth's axis. The axis the Earth spins on is not straight up and down when you look at the orbit that the Earth takes around the sun. It is tilted at 23 degrees. If you look at a globe, you'll see something called the arctic circle. Winter happens in the northern hemisphere where the axis is pointed away from the sun. If you are north of the arctic circle, you will have a period where the sun never rises in the winter. As you head south, the day period gets longer and as you go south of the equator, you find it has gotten longer still until you are at the south pole and find that it has 24 hour a day sunlight for a period.


Bottom line, the north pole points away from the sun in northern hemisphere winter and the closer you are to it, the shorter the days.

The good stuff isn't overly salty and it certainly isn't fishy. Try some on a piece of toast with some cream cheese. Sadly though, the good stuff is really expensive.

If you want to get an idea at a reasonable price, go to a good sushi place and get an order of Masago sushi.

There are a number of different causes. Sometimes, something specific to that product happens. Like if there is a bad frost in an apple growing area and all the apple blossoms get destroyed, then the price of apples will rise as they have to be brought in from other areas.

Sometimes price rises are more general. If the central bank creates money faster than the amount of goods and services is growing, then all prices will rise, in roughly the same proportion.

Finally, a rise of price of one good can cascade through the economy. Russia was a big gas and oil exporter. With their supplies closed off, most industries have increased costs. They have to pass these costs along to their customers, so most prices rise.

What's going on now is a combination of the last two reasons and then the economic disruption of the Covid pandemic.

What can be done about them? Not much actually. Price controls just cause prolonged shortages. The high prices will bring in more suppliers and pricing will moderate, albeit at a new generally higher level.
