> you might want to buy a glucose testing kit to see if you have diabetes.

Just come to the fucking hospital and don't dick around with that.

For real, most shit people come to the ER with is such bullshit but sugars causing polydipsia and polyuria (excessive thirst and urination) actually count as an emergency and aren't going to magically fix themselves if you just wait it out.

I get that healthcare can be prohibitively expensive in the US. But if you fuck around mulling over what to do with the "maybe I have diabetes" armchair doctor shit, you're just going to get sicker and sicker, possibly to the point of being in a coma in the ICU or even dying.

This is where my answer is a bit messy. Imaginary numbers can be thought of that way, but using them for 2d space is an application.

We do have quaternions. This gives us 3 imaginary numbers, we call i, j and k, where squaring any of them gives -1, and ij = k, jk = i and ki =j. Weirdly, we lose commutivity here. ij = k, but ji = -k. Reversing the order gives a negative result.

It is possible that what seems random to you actually has a pattern. There are several factors contributing to the level of thirst. Let's first exclude physical expenditure (sweating), because that would be too obvious. And let's just assume that we didnt actually go without water for a long time.

The things going on in your digestive tract are far less obvious than other losses of water. You need to know one fact about the body: anything that is inside your digestive tract is basically outside of your body. So once there is a lot of secretion of digestive fluids this counts as loss of fluids from the body to the outside world. So then you can suddenly feel like you have lost a lot of water when it is actually still inside you. And then another curious thing can happen, once the food has reached the end of the digestive tract most of that water gets re-absorbed, and then you suddenly have to pee and you wonder why, because you didnt actually drink that much.

edit: or Diabetes. I guess this needs to be mentioned given the prevalence. Thirst that does not go away with drinking should be taken seriously, it is not normal.

Electricity is a fairly recent discovery. When it was discovered and formally described by science, the world was already connected to a decent degree, so as the knowledge of electricity was passed along, so were the units.

On the other hand, physical quantities like distances and weights were measured independently by different cultures basically since the dawn of civilization, so every culture developed their own set of units.

If electricity were discovered by say, ancient Greeks and ancient Chinese, we would most likely have two different sets of units for electricity.

Looking online I can see that W is used for the Whole numbers, but I never saw the W symbol used in all my math classes.

Personally I learned that 0 was a natural number and looking online it is said that 0 was not included in the original definition, but was later added. To avoid mistake, N* is often used to indicate that it contains 0. At the end, it's not really that important but it's good to know !

There is front end and back end code. Front end code is like Javascript that gets downloaded to your local machine and it is run using your own computing resources. This part you can steal.

What you can't steal is backend code. Google's search function on their main page sends your text input into their own proprietary servers and returns the results to you, so their searching algorithm is nowhere in the web page source code.

> You can owe the mob 5 sheep. Which means that if you want to have 2 sheep, you'd better buy 2 sheep so you can pay your debts before you start farming wool.

Your math is wrong. If you owe the mob 5 sheep and you want to have two sheep, you're going to need to buy 8 sheep (5 for the mob, 1 for the "big" and 2 for you).
