Vortices that form in quantum liquids can now be studied with a camera that uses particle-like disturbances to take images instead of light. Normal cameras can’t capture these whirlpools, so the device may lead to a more detailed understanding of how they form.
Swirl a spoon in a cup of tea and you can easily create a vortex. But researchers have long struggled to predict exactly how these tiny tornadoes form or how they …
