Helium is inert, which makes it useful in a lot of different industries. But helium’s colorless and odorless non-reactivity ...
Sound is usually treated as the most familiar of physical phenomena, the background noise of daily life rather than a frontier of fundamental physics. Yet in laboratories around the world, carefully ...
A quiet revolution is taking shape in the world of physics, and it doesn’t rely on exotic particles or massive particle colliders. Instead, it begins with something much more familiar—sound.
The acoustic properties of an ultracold fermion gas have been measured either side of the superfluid transition temperature in an experiment that has been described as “near perfect” and “beautiful”.
At University College London, Lesley sings I Dreamed a Dream inside an MRI scanner to reveal how her vocal tract acts as a ...
The range of materials that concrete contains, such as stone, chalk, and sand, scatters normal sound waves, making clear ...
The pressure variations of a sound wave can make a gas bubble in a liquid periodically shrink and grow. At certain temperatures and pressures, the bubble may implode to generate a huge pulse of energy ...
Scientists at MIT have directly captured signs of “second sound” in a superfluid for the first time. This bizarre phenomenon occurs when heat moves like sound waves through an unusual state of matter.
