The simplest ideas in mathematics can also be the most perplexing. Take addition. It’s a straightforward operation: One of the first mathematical truths we learn is that 1 plus 1 equals 2. But mathematicians still have many unanswered questions about the kinds of patterns that addition can give rise to. “This is one of the… Continue reading Graduate Student Solves Classic Problem About the Limits of Addition

In the mid-1950s Marthe Gautier, a young French doctor and cytogenetics researcher, led a cutting-edge experiment to investigate the cause of Down syndrome. She painstakingly cultured cells in a ramshackle lab until one day she discovered an extra chromosome in the cells of people with Down syndrome. This proved beyond a doubt that Down syndrome… Continue reading Who Discovered the Cause of Down Syndrome?

After her adventures in Wonderland, the fictional Alice stepped through the mirror above her fireplace in Lewis Carroll’s 1871 novel Through the Looking-Glass to discover how the reflected realm differed from her own. She found that the books were all written in reverse, and the people were “living backwards,” navigating a world where effects preceded… Continue reading How the Universe Differs From Its Mirror Image

Geometry is one of the oldest disciplines in human history, yet the worlds it can describe extend far beyond its original use. What began thousands of years ago as a way to measure land and build pyramids was given rigor by Euclid in ancient Greece, became applied to curves and surfaces in the 19th century,… Continue reading How Did Geometry Create Modern Physics?

For all the world’s linguistic diversity, human languages still obey certain universal patterns. These run deeper than grammar and syntax; they’re rooted in statistical laws that predict how frequently we use certain words and how long those words tend to be. Think of them as built-in guardrails to keep language easy to learn and use.… Continue reading Whale Songs Obey Basic Rules of Human Languages

They started by imagining a very fine grid superimposed on their fluid. They then computed how long particles spent in each square of the grid, on average. In some squares, the fluid acted like a rushing river: Particles tended to sweep straight across the square, spending only a brief period of time there. In other… Continue reading New ‘Superdiffusion’ Proof Probes the Mysterious Math of Turbulence

To find out if KIBRA and PKMζ work together in response to synaptic activity, the researchers used a technique that makes interacting proteins glow. When they applied electrical pulses to hippocampal slices, glowing dots of evidence appeared: Following bursts of synaptic activity that produced long-term synaptic strengthening, a multitude of KIBRA-PKMζ complexes formed, and they… Continue reading The Molecular Bond That Helps Secure Your Memories

A stain drying on the counter. A raindrop splashing onto the sidewalk. A pile of gravel settling. Historically, such phenomena have rarely caught the attention of physicists, as they seem mundane and devoid of fundamental significance. At the same time, these everyday happenings are also deceptively hard to understand. Out of balance and disordered, they… Continue reading Finding Beauty and Truth in Mundane Occurrences
