I'm not getting satisfied with Euclid's concept of straight line and shortest distance b/w to given points is a Straight line,At present I'm studying "The Elements".

Can you people know any alternatives on this topic?
I'm interested to study them.


Thanks:shy:

By today's standards, Euclid wasn't entirely rigorous. In 1899, Hilbert gave a course on axiomatic geometry from his own formulation. Whereas Euclid describes geometry in 5 axioms, Hilbert does the same with no less than 20.

Euclid relied more heavily on common sense in proofs. Granted, all proofs require an amount of common sense, it's clear that Hilbert assumed even less.

As for Euclid's definition I.4 of the straight line, it is NOTORIOUSLY vague, so you are not alone.

I think I'm alone but so many are here,its great.
I'm very confusing with dimension concept too,not satisfying with concept of 3rd Dimension.
