Using 10,000 atoms and 1 to probe the Bohr-Einstein debate
The double-slit experiment has often been described as the most beautiful demonstration in physics. In one striking image, it shows the strange dual character of matter and light. When particles such as electrons or photons are sent through two narrow … Continue reading

What on earth is a wavefunction?
If you drop a pebble into a pond, ripples spread outward in gentle circles. We all know this sight, and it feels natural to call them waves. Now imagine being told that everything — from an electron to an atom … Continue reading
