Milton Cole of Pennsylvania State University in University Park thinks that tiny variations in the crystalline structure of the cesium could somehow provide a foothold
for the superfluid.

Esslinger and his colleagues wondered if they could observe the transition from non-
superfluid to
superfluid, and use this as a model
for studying the onset of superconductivity.
Now
for the first time, researchers have made and photographed a

In the 1970s, Brinkman worked on
superfluid helium with Anderson and Douglas Osheroff, both Nobelists but

superfluids make
for strange bedfellows: One is famous
for being so dense that light can't escape, and the other is a bizarre liquid that flows without friction.
For instance, at low temperatures liquid helium's properties change dramatically, becoming a «
superfluid» that can overcome friction.
In a class of

When Cornell physicists Robert Richardson, David Lee and Douglas Osheroff received the 1996 Nobel Prize
for their discovery of the
superfluid state of liquid helium, it was only the beginning.
Superfluids don't exist in the everyday world — it's too warm
for the necessary quantum effects to hold sway.
The next step
for Khoury and Berezhiani is to figure out how to test their model — to find a telltale signature that could distinguish this
superfluid concept from ordinary cold dark matter.
Apple went a little hybrid with use of both buttons and touch
