to gases, which spread to fill their containers.<br />

But they were far less dense than any liquid that<br />

exists under normal circumstances, and<br />

maintained their liquid state through a<br />

process known as quantum fluctuation. The<br />

researchers cooled a gas of<br />

potassium atoms cooled to minus 459.67<br />

degrees Fahrenheit (minus 273.15 degrees<br />

Celsius), close to absolute zero. At that’s a state<br />

of matter where cold atoms clump together<br />

and start to physically overlap. These<br />

condensates are interesting because their<br />

interactions are dominated by quantum laws,<br />

rather than the classical interactions which<br />

can explain the behaviour of most large bulks of<br />

matter.<br />

Potassium condensate droplets, however,<br />

aren't dominated by those other forces and have<br />

very weakly- interacting particles, and<br />

therefore spread themselves across much wider<br />

spaces — even as they hold their droplet<br />

shapes. Compared t o similar helium<br />

droplets, the authors write, this liquid is<br />

two orders of magnitude larger and eight<br />

orders of magnitude more dilute.<br />

When researchers pushed two of these<br />

condensates together, they formed droplets,<br />

binding together to fill a defined volume. But<br />

unlike most liquids, which hold their droplet<br />

shapes together through the electromagnetic<br />

interactions between molecules, these droplets<br />

held their shapes through a process known<br />

as "quantum fluctuation “emerges<br />

from Heisenberg’s uncertainty principle.<br />

These new droplets are unique in that quantum<br />

fluctuation is the dominant effect holding<br />

them in their liquid state.<br />

Matching Feature Comes to India<br />

While the belief 'there are seven lookalikes in the<br />

world' may not be true to the word,<br />

according to Google Arts & Culture app there is a<br />
