In quantum electrodynamics, the bare charge of an electron is infinite, but the dressed charge is finite. The bare electron shields itself by polarizing the virtual electron-positron pairs of the nearby quantum vacuum to reduce its coupling at large distances to [latex display=”true”] \infty … Continue reading →

A focussed light beam can trap a small particle, such as a micron-sized latex sphere (or biological cell). If the sphere is much larger than the light’s wavelength, ray optics suffices to explain the trapping. Light bends as it passes … Continue reading →
