Physicists have demonstrated a new type of tunable liquid lens whose focus can be changed simply by varying the pressure on it. The lens is formed from the curved interface between a liquid and air at ...

The Romantic poet John Keats once defined a state of mind wherein a person "is capable of being in uncertainties, mysteries, doubts, without any irritable reaching after fact and reason." He called it ...

The questions in this quiz are suitable for GCSE physics students studying calculating pressure, pressure in a liquid and atmospheric pressure. If you struggled with the quiz, don't panic - we've got ...

The movement and space between particles in a fluid affects the amount of pressure the fluid exerts. This means that the pressure in a fluid changes depending on its height, depth and temperature. The ...

Pressure-temperature (P-T) phase diagram of a NaYbSe2 single crystal. Courtesy: Run-Ze Yu Researchers in China report that they have observed both superconductivity and an insulator-to-metal ...

In a significant advance for semiconductor manufacturing, mechanical engineers created a simulation that makes it easier to choose environmentally friendly water jet and underwater ultrasound ...

In a demonstration that defies basic assumptions in physics, researchers have created liquid sodium at room temperature. As a member of the alkali metals—the first column in the periodic table—sodium ...

University of Salford provides funding as a founding partner of The Conversation UK. When we boil a kettle, we observe what scientists call a phase transition: the water changes from being a liquid to ...
