oh no, not at all; I completely agree that people should study only what they want. but schools are really not quite that, and they teach everyone basics  of everything, math included, and I can only assume one knows how to get their taxes math by age 9(it really is just taking a number and multiplying it by another with a calculator), so yeah; assuming that you learn math all the way through highschool, that's really bad imo :/

Jell, when do people in your place learn quad?

I think at age 13-15, I'm not sure.
Fun story about that, in the final grades of high school in the Netherlands people have to use graphic calculators for Math (TI-84 and such). You can program simple programs on these things, so everybody had a program for those mathematic formulas, such as the quadratic formula, or trigonometric formulas. I was one of 4 or so people in my year who could actually make such programs, so most people came to me to write it for them. As such, I've never had a quadratic solver program on my own calculator, because I had implemented it in so many other calculators that I was one of the very, very few people who had actually memorized it.

Also, two of those other guys who could program these things were close friends of mine. Math, chemistry, physics and biology were far too easy for us, so we often spend these classes programming on our calculators. After a little while it became a competition among us to make these programs as light and efficient as possible. The quadratic solver took four lines (one to input the coefficients, one to solve and give the determinant which was often required to give on tests, and two for the two solutions) and the trigonometry program took even less thanks to clever use of complex numbers.

I also programmed my calculator to show the Batman logo whenever I booted it up, a very simple mine dodger/snake type game, a very, very simple RPG and one of my greatest moments, an oracle type thing which randomly generated a prediction for your future with a few sub-programs to determine the scenario, the people in that scenario and finally a special program to actually print the thing out on the screen because the standard font was too large to fit on the screen. For example: "Batman, Natalie Portman, Super Mario, George W. Bush and you team up together to form the new Power Rangers."
It would also occasionally show simply "You will die", which was always fun when it showed up.

If you were to rate my all of my posts together on a scale of 1 to 10, what would you rate it?

On a scale of 1 to 10.

probably a solid 3.5

a liquid 3.6

a gaseous 3.7

A plasma 3.8

a superfluid 3Ï€/2

pi looks weird in this font.  

A circumferential 3.1415926535897932.

(Question)
What are the highest possible numbers you can make when adding up the angles (in degrees) of a spherical triangle? I know about the 90-90-90 triangle, but is that the maximum? All I've read about says that the sum of the angles is over 180.

Also, what comes next?
Line - Circle - Sphere - ? - ?

I guess you could have a straight line across the sphere, which can be seen as a triangle with three angles of 180 degrees. You could define a triangle of 540 degrees.

Line - circle - sphere - hypersphere. I think you can denote the dimension as 4-hypersphere, 5-hypersphere, etc.

But a triangle is defined as a shape with 3 vertices. Or is it different in more than 2 dimensions?

Can you have a 3-sided 3D figure? If you said it earlier I did not read that.

An angle of 180 degrees is still an angle. But if that bothers you too much, you can have the three angles be infinitesimally close to 180 degrees and still get the same answer.



Depends on how you define a side. A sphere can be considered a single sided 3D figure. But if you mean straight sides, then no. You need at least four verteces to define a 3D polygon, which span up four sides.

in a multiplayer game, (like minecraft or whatever), how does the server tell one player apart from the other? i imagine if the clients didn't sign their communications, one person could impersonate another. but does the minecraft server thing really bother to implement pgp or something? i doubt it

I guess that each user has an unique key that is so long that it becomes practically impossible to impersonate.

From what I understand, when you join a server you send the server a "session" which tells it what user you are. Because of this, you can have a user join a decoy server (by way of social engineering) and have that server hijack their session and log in as them on any server. You can OP yourself and such like that.

In Minecraft, every entity has it's own unique ID for that world so it's able to distinguish one from the other. This also applies to players (which I don't think is per world) and the ID is shown in the console when they login.  

How come lots of film stars are dying this year so far?

Lots of famous people die all the time. This isn't any extraordinary.

So the results are out and You were right with this task, props! It seems it all would be a piece of cake for You, that's incredible. I've got 60% of the points, but it doesn't give me anything, meh.

It is not a very difficult task, but because it consists of a set of non-linear equations it just takes a lot of time to solve properly.

What do you think the world will be like in 10 years? 50? 100?

I have ∂ρ/∂t and ∂(ρu)/∂t. does dividing the latter by the former give me ∂u/∂t?
