Not true. Elliptic curves can be characterized intrinsically via Chevalley's theorem on algebraic groups.

### Re: How come there is no such thing as 1 dimensional geometr

I think elliptic curves are a pretty successful example of one-dimensional geometry...

Finally wrote my first paper. Hopefully many, many more to follow.

### Re: bumber theory, no of primes

Note that for x = 2500 the right-handle side is less than four.

### Re: "Numbers" Discussion

I like that there's a severe dropoff between 9th grade / freshman and 11th grade / junior, presumably due to a widespread inability to spell the word "sophomore." (Also, note that all those grades get doubled up, because you're a freshman in high school and then again in college...)
