> A number is a mathematical object used to count, measure, and label.
>Counting is the process of determining the number of elements of a finite set of objects.
>Measurement is the numerical quantification of the attributes of an object or event, which can be used to compare with other objects or events.
>Nominal numbers are categorical, which means that these are numerals used as labels to identify items uniquely.
All three of the main ways that Wikipedia describes numbers invoke the word number in their own definition. Is this like how linguists have difficulty escaping the self-referentiality of pure language, where a real language must rooted in something intuitive or experienced?

Also, without making Wikipedia’s error: What is a number?

What is gravity?
I mean I know it's a force that draws things together according to their mass but what (ACTUALLY* is it?
Like what is it made of?
And why does it draw things with mass together?
How did it did it originate in the unvierse?

I have my own theory that nobody seems to have addressed which is basically that it was an intentional decision created by one individual, likely a leader of a specific tribe who decided it would be convenient to have a sound he could use to refer to something. So, for instance, he wants a term for "rock", so he simply comes up with a noise for it and gets the attention of the other tribe members by making that noise while interacting with the rock in some way. Eventually through pattern recognition abilities the others catch on and with that we have the first language with a grand total of one word. This process repeats many times, likely over many generations with more and more words added over time.

I haven't heard of anyone explaining why this idea wouldn't work. I've heard it said that humans couldn't have sat down and decided to make a language because they would have already needed a language in the first place, but that only applies if the idea was executed by a group rather than a single specific individual.

If this was so dangerous, wouldn't we see extreme increases in dementia, alzheimers, lower IQ, cardiovascular and pulmonary problems with people who live in all urban areas relative to people who have lived in rural areas for decades? This would look very obvious, but I do not see such data to confirm it is true.

What would a proof of the Riemann Hypothesis look like if we had it? What is the problem?

The Biochemists and Biophysicists calculation is a healthier $75,000, but I'm not sure that a person with a bachelors degree in Biology can easily choose those areas for a PhD. I suspect Biology is so low because it is apparently highly competitive. Many people enjoy the field, I suppose, so many that they are making only about $4,000-$5,000 per month after taxes with a PhD.

What is the best rock and why is it sedimentary?

Why can't you factor out the sum of two squares? Like, I get how it works with the difference (because if you factor one side out then you have one side of the square), but why wouldn't it work when you're summing the two?

How do you find the ABC values in the standard form of linear equations?

Ax + By = C

I've looked all over my notes and this is never actually explained.

Dude... what?

The power of a power rule states that:

>(a^m)^n = a^mn

But unless I'm doing something wrong, this doesn't actually hold true, because if you have an expression like:

>(-4y^2) (3y)

Then you end up with 12y^3. But if we just multiplied the exponents like in the power to a power rule, we would expect to have 12y^2 (since 2*1 = 2). What am I missing here?

there like a triangle that forms inside of the main circle where anystep from any initial point of your first step will take two steps but i have no idea how to calculate it and that doesnn't even include moving in a completely randowm direction

I'm taking a remedial math class at my second-rate college and it's going really good and I like it lots :)
