A profound fear of his own mortality.

Why this year’s Seder will bring a whole new understanding to the holiday.

It’s a stereotype that’s unfortunately true—and spans many religions.

The most difficult aspect of being a rabbi? Dealing with Jewish people.

At the New Shul in Manhattan, being Jewish isn’t everything.

Rabbi Niles Goldstein helped create a modern synagogue that’s home to all sorts of untraditional ideas.

Sometimes too many options lead to disengagement, says the New Shul rabbi.

How martial arts enabled a spiritual leader to open up.

A conversation with the founding Rabbi of the New Shul in Manhattan.

A rock tune celebrating his work has become an Internet hit. But did it please the professor himself?

As the celebrated mathematician writes his memoirs, he reflects on the combination of good luck, hard luck, and constant dreaming that made his life a success.

The mathematician has long believed the traditional understanding of market fluctuations would need to be replaced with his fractal model. Unfortunately, he says, “my time…has come.”

The word “fractals,” which Benoit Mandelbrot invented, has caught on with everyone from kids to club owners.

The father of fractal geometry marvels that his work has led to computer renderings of natural shapes that are indistinguishable from the real thing.

The geometry of fractals may be relatively new, but humans—especially artists—have perceived them in nature for ages.

How a quest to combine aesthetics with mathematics produced one of math’s most famous, and gorgeous, images: the Mandelbrot set.

What are fractals? The man who invented the term—and the geometry to go along with it—explains how complex natural shapes such as mountains and coastlines can be represented mathematically.

A conversation with the mathematician and Professor Emeritus at Yale University.

“We live in an era where science is important to the decisions we make,” the Harvard physicist points out.

Why the Harvard physicist recently tried her hand at writing a libretto.

The Harvard physicist describes one of her most surprising moments of discovery.

The Large Hadron Collider in Switzerland will test some of physicists’ most radical conjectures, from supersymmetry to extra dimensions of space.

Because dark energy doesn’t dilute as the universe expands, it will ultimately speed up that expansion exponentially, turning the cosmos into a giant void.

The Harvard scientist explains the daily work of a particle physicist and what problems lie at the cutting edge of her field.

A conversation with the professor of theoretical physics at Harvard.

The real issue is not whether we can prove that climate change will or will not occur within 30 years. It’s that we don’t really know for sure, but we […]

In energy technology, it’s clear if your invention works or not. Either the device saves energy and people buy it and find out, or it doesn’t.

The reason we haven’t innovated enough in energy technology is because energy used to be cheap.

A process that mimics photosynthesis could create a fuel that provides energy in a convenient form.

“When carbon dioxide is free to emit, we emit it like it ain’t going out of style.”
