They're equations that combined the formerly separate theories of electricity and magnetism. They show how they aren't actually two different forces, but two different aspects of a single phenomenon. It is one of the earlier unifying theories for what would become known as four fundamental forces.

  1. One equation (Gauss's Law) describes the electric field generated by a static charge.

  2. One equation (Gauss's Law for Magnetism) shows that there are no magnetic charges (monopoles--although some theories postulate their existence no one has found one to date).

  3. One equation (Faraday's Law) shows how an electric field is created by a magnetic field changing in time.

  4. One equation (Ampere's Law) shows how a magnetic field is created by an electric field changing in time.

As you may tell from the equations' names Maxwell did not necessarily come up with the equations, but he put them together and understood many of their implications. Any classical electromagnetic properties can de derived from the equations.

Perhaps the most profound implication of Maxwell's equations are electromagnetic waves. He realized that a changing electric field will generate a changing magnetic field, which in turn would create a changing electric field, which in turn would create a changing magnetic field, ad nauseam. From this he realized that electric and magnetic fields could generate a self-propagating wave. Combining the equations you can calculate the speed of propagation which just so happens to be the speed of light...

Could you go into a bit more detail? I mean, a book publisher actually prints books and has them shipped to bookstores. But a game on Steam doesn't need to be printed or distributed, and Steam barely has any ads in the first place. So a videogame publisher does, what? Just the ads? Are they basically just an advertising agency specialized in videogames?

The Egg cooker has a fixed volume. If you load all the eggs in the same chamber to cook, it takes less water to fill to the ideal level of water than if you only have 1 egg in the same chamber.

Egg cookers where each egg has its own chamber are not expected to have the same problem but the design is usually more expensive.

Yes, and it is unlikely that what you are 8 hrs prior is making it's way out of you. After the small intestine is the large intestine, and then you can poop it out. Gut motility varies from person to person, and "normal" can be anywhere from 16 hrs - 2 days to get through your system.

Curious how long yours is? Eat corn and see when it passes. Or eat a bunch of beets and wait till you see purpleish-red poop!

Pounds are a unit of force, while kilograms are a measure of mass, true. However, on Earth they are interchangeable because the difference between a measure of force and a measure of mass in this case is gravity. The pound takes into account gravity, and mass does not.

However, so long as they are in the same gravitational field, they are effectively the same unit. You can think of it as adding gravity to kilograms to make it a force or removing gravity from the pound to make it a unit of mass. Either way, you end up with comparable results if the gravity is the same.

It also does not matter what gravity it is, on the Moon, Earth, Jupiter, or a neutron star. So long as the gravity for both is the same, kilograms are effectively a unit of force and pounds a unit of mass.

Indeed, you have repeated the part I already understand, but it feels like saying that, "The probability that I could transform into a duck are the same in this moment that they were 10 seconds ago according to quantum physics". At some point it seems that a certain number of throws in a row would force us to consider things differently. If I did indeed turn into a duck, folks would not shrug that off as a quantum possibility, even if highly improbable. Hypothetically, if you had one quintillion throws in a row, you would have a team of scientists on the scene and it would make international news. Nobody would ever shrug that off and say "ah well, the probability of the next roll doesn't change." At that point, all involved scientists and statisticians and any interested parties would effectively be falling victim to the gamblers fallacy, but it still seems to make sense that they would, right?

It's not "taking days or weeks off" from life. You said it yourself, it's a pain in the ass with laughable compensation (that is taxed!) No one has the "means or desire" to miss their regular life for that.

They need to make jury duty worth everyone's time. The way it is, clever but unscrupulous people will finagle out of jury duty because it pays shit and their jobs don't have to pay them for the lost time.

So if they want a demographic of the overall population, they need to entice everyone to actually want to do it. Make the process more efficient, require employers to pay regular wages, etc.

When you see someone doing this, it's because they're taking a shortcut, usually without even realizing that they're doing it. On the surface of the earth, where acceleration due to gravity is roughly 9.81m/s^2 no matter where you are (it DOES change a bit but not by a huge amount), then we can use the force an object applies to the ground to determine what its mass is. In other words, we can treat a unit of force like a unit of mass. Doing so will get you yelled at by physicists, so don't do this in any scientific or engineering environment.

They advertise and essentially endorse the game. A small time developer can publish their own video game, but they're going to get a lot more sales by having a bigger name backing their funding and attaching their name to it. It's similar to someone self-publishing a book they wrote. A lot of those are never heard of, but going through a large publisher whose sole purpose is making it a success financially will be a lot more profitable

Just do what I did when they asked me if there was any reason I couldn’t serve on the jury, I just said I was racist and sexist and they didn’t pick me to serve on the jury. Worked like a charm

While pounds are indeed a unit of force, most people treat them as a unit of mass assuming Earth's gravity.

When someone says that 1 pound is 454 grams, they mean a mass that weighs 1 lb in Earth's gravity has a mass of 454 grams.

Because "not 6" is 5 times more likely to happen than 6 on a six sided die in a single throw. You're focusing on the one combination result that is 6 for all 1000 dice rolled and comparing it to the many combinations that are not that one single very specific result you want.

If the billionaire gave you a die to roll 1000 times to get a single specific order of numbers like "123545453621145..." you'd still have the same horrible odds of getting that one result.

Now if it were 1000 die to roll and the result must be all 6s except one single roll anywhere among the 1000 rolls, your odds of getting that goes up because there are more than 1 results that match that criteria.

Make it must get only one 6 anywhere out of 1000 throws/die while the rest are not 6 and your odds are much better because there are even more results that match that criteria.

Going back, if you had already thrown all 6s for 999 throws and you only have to throw the last die, your chances are 1/6 because the result you want is 1 out of 6 results now. The more 6s you got, the probability of getting the rest of the throws as 6s went up because there are less possible results available for the rest of the row of throws. Up until you achieve all 6s, at which point the probability is now 1 out of 1.

Because the measurement of force on an object of a particular mass due to gravity is effectively identical everywhere on planet Earth. For the general purposes of needing to know weight, fluctuations in the force applied by gravity aren't even rounding errors - they are too minuscule to matter.

Given that that force is effectively a constant in Earth-gravity, we can convert between mass and force on Earth.

From a more philosophical standpoint, rights are accompanied by responsibilities. Sometimes, we codify those responsibilities in law. For example, you have the right to freedom of speech. You have the responsibility not cause harn to the person, property, or reputation of another through speech that is not true, hence libel and slander laws. You have the right to be armed. You have the responsibility to only use weapons for legitimate purposes. You have the right to a trial by a jury of your peers. You have the responsibility to serve as a juror when called upon to do so.

Sometimes I think we forget how absolutely incredible it I'd that most of us live under a system where human rights are codified I'm law. Most of our ancestors would be floored at the rights we enjoy. Serving on a jury is a very small price to pay for a legal system with fairness and objectivity as its goal.

In almost all situations, brakes can exceed the traction the tires have to the road, so applying additional braking force to the wheels will not allow you to slow down more quickly. To put it another way, apply brakes "too hard" can already exceed the tires ability to slow the car down through friction with the road, as can be felt when the car slides while you're trying to brake. ABS is a system that keeps brakes from locking up by lessening the braking force applied to the tire to the point where it has traction again or is within it's braking threshold.

One thing that isn't touched on here is that engine compression applies a passive slow down and can be very important for situations where your brakes might overheat, such as descending a steep and long hill.
