"The zeta function is probably the most challenging and mysterious object of modern mathematics, in spite of its utter simplicity"

M.C. Gutzwiller - Chaos in Classical and Quantum Mechanics (Springer-Verlag 1990)

"We may - paraphrasing the famous sentence of George Orwell - say that 'all mathematics is beautiful, yet some is more beautiful than the other.' But the most beautiful in all mathematics is the zeta function. There is no doubt about it."

Polish cosmologist Krzysztof Maslanka

"...a variety of evidence suggests that underlying Riemann's zeta function is some unknown classical, mechanical system whose trajectories are chaotic and without [time-reversal] symmetry, with the property that, when quantised, its allowed energies are the Riemann zeros. These connections between the seemingly disparate worlds of quantum mechanics and number theory are tantalising."

Critical Strip Explorer v0.67, a wonderful applet produced by Raymond Manzoni for this site - explore the behaviour of the Riemann zeta function in and around the critical strip in a highly visual, interactive way. The resulting images are quite astonishing!

more applets for exploring the behaviour of the Riemann zeta function can be found on Glen Pugh's homepage, as well as here.
