I spent my adult life as a scientist, and science is, essentially, the most successful approach we have to try and understand the vast mysteries around.

We spend our lives on a thin slice between the unimaginably small scales of the atoms that compose us and the infinitely large scales of galaxies.

As we develop better technologies for probing the brain, we detect more problems.

The three-pound organ in your skull - with its pink consistency of Jell-o - is an alien kind of computational material. It is composed of miniaturized, self-configuring parts, and it vastly outstrips anything we've dreamt of building.

Among all the creatures of creation, the gods favor us: We are the only ones who can empathize with their problems.

One of the most impressive features of brains - and especially human brains - is the flexibility to learn almost any kind of task that comes its way.

The brain runs its show incognito.
