In both cases it is clear that the base of "imaginary" numbers has very real meaning. Mathematicians may construct airy or ephemeral glissandos of their own amusement. But, as reality is real, these must have some practical application, even if the technology has not yet been invented. Link to post Share on other sites

But, as reality is real, these must have some practical application, even if the technology has not yet been invented.After over 200 years this is still considered the most amazing equation in mathematics. If you substitute pi for x you gete ^ (i*pi) = - 1 or e^(i * pi) + 1 = 0. This connects the busiest numbers in mathematics ; 1, 0, i, e and pi. The sin and the cos functions are periodic and basic to the physical harmonies: light and time. Pendulums rock themselves to sleep to the tune of sin and cos. And the waves of light are described by these. In addition, the sin and cos functions are the basis of Fourier series and integrals which are basic to all of the mathematics used in physics. It is a remarkable equation.Ba'al Chatzaf Link to post Share on other sites

Archimedes using the limit concept figured out the area of a circle and the constant pi without the zero.Ba'al Chatzaf Link to post Share on other sites
