![The microwave sky as seen by the ESA Planck satellite. This map shows the tiny departures from uniformity of the infant universe at about 1/1000th its present size as seen from space at microwave frequencies. These tiny fluctuations---at approximately one part in 100,000---subsequently grew to turn into the structures that we now observe in the nearby universe.

In 1964 Arno Penzias and Robert Wilson of the Bell Telephone Laboratories discovered the almost perfect blackbody microwave glow from the Big Bang. They found this glow to have a nearly uniform temperature of 2.7255 K that did not vary with position in the sky. Since then, as a result of immense effort and ingenuity, […]

Spontaneous symmetry breaking lies at the heart of modern physics, shaping our understanding of matter, forces, and even the universe itself. From condensed matter physics to particle physics and cosmology, spontaneous symmetry breaking unifies phenomena that at first seem worlds apart.

Few things stir emotions and financial markets quite like artificial intelligence, yet too few people understand how it’s made, how it’s measured, how it intersects with the law, and what its societal implications may be. The most well-known issues, such as misinformation, hallucinations, “nudify” apps, and the like, are the tip of the iceberg. I […]

A good question, you might say, and one that some astronomers asked when I presented a paper the subject at a recent meeting of the American Astronomical Society! The philosophy of science and of specific sciences such as physics, chemistry, and biology are well-developed fields with their own books and journals. These studies are important […]

The soul of modern complexity science lies in understanding, training, and controlling the interactions among millions of elementary degrees of freedom to generate emergent dynamics; in other words, to shape the effective physical laws that govern the behavior we observe. This goal has so far been achieved primarily in computer simulations and in models that […]

Human-built spacecraft have visited every single planet in our solar system, as well as several comets and asteroids. We have landed robotic spacecraft not only on Venus and Mars but also on Titan, the largest moon of Saturn. Spacecraft have dived down close to the Sun’s surface and others have escaped the solar system, flung […]

My first week of doctoral coursework at Johns Hopkins in 2017 came with four hundred pages of reading. The second week came with five hundred. I had been reading science for a living for a decade — as a journalist, a teacher, a writer — and by the middle of the term it was an […]
