Will there ever be another Einstein? This is the undercurrent(潜流) of conversation at Einstein memorial meetings throughout the year. A new Einstein will appear, scientists say. But it may take a long time. After all, more than 200 years separated Einstein from Isaac Newton.

Many physicists say the next Einstein hasn't been born yet, or is a baby now. That's because the search for a unified theory that would explain all the forces of nature has pushed current mathematics to its limits. New math must be created after the problem can be solved.

But researchers say there are many other factors working against another Einstein appearing anytime soon. For one thing, physics is a much different field today. In Einstein's day, there were a few thousand physicists worldwide, and the theorists who could argue with Einstein probably would fit into a streetcar with seats to spare. Education is different, too. One key aspect of Einstein's training that-is little noticed is the years of philosophy he read as a teenager --- Kant, Schopenhauer and Spinoza, among others. It taught him how to think independently about space and time and it wasn't long before he became a philosopher himself.

And Einstein was a clever musician. The interplay between music and math is well-known. Einstein would play his violin hard as a way to think through a knotty physics problem.

Today, universities have produced millions of physicists. There aren't many jobs in science for them, so they go to Wall Street and Silicon Valley to apply their analytical skills. Those who stay in science don’t work alone and they sometimes do experiment together which takes years.

It's hard to imagine a renegade(背叛者) like Einstein standing it. “Maybe there is an Einstein out there today,” said Columbia University physicist Brian Greene, “but it would be a lot harder for him to be heard.”
