The Physics and Philosophy of Time – with Carlo Rovelli

The Physics and Philosophy of Time - with Carlo Rovelli From Boltzmann to quantum theory, from Einstein to loop quantum gravity, our understanding of time has been undergoing radical transformations. Carlo Rovelli brings together physics, philosophy and art to unravel the mystery of time. Subscribe for regular science videos: http://bit.ly/RiSubscRibe Carlo's book "The Order of Time" is available now - https://geni.us/JjwvO Watch the Q&A: https://youtu.be/NXcu0BlbTrM Time is a mystery that does not cease to puzzle us. Philosophers, artists and poets have long explored its meaning while scientists have found that its structure is different from the simple intuition we have of it. Time flows at a different speed in different places, the past and the future differ ...

Electric Charge: Crash Course Physics #25

Electric Charge: Crash Course Physics #25 Moving on to our unit on the Physics of Electricity, it's time to talk about charge. What is charge? Is there a positive and negative charge? What do those things mean? In this episode, Shini talks about electrostatic forces, electrical charge, Coulomb's law, and the force between charged particles.

Superfluid used to make sounds that might be heard in neutron star

Superfluid used to make sounds that might be heard in neutron star By Abigail Beall Physicists have sent sound waves through a superfluidChristine Daniloff, MIT Nobody will ever be able to hear the sounds produced inside a neutron star, but a group of scientists have created what might be the next best thing. The team, led by Martin Zwierlein at the Massachusetts Institute of Technology, listened to sounds moving through a type of superfluid called a perfect fluid – a gas with the lowest possible amount of friction. Although the conditions are totally different, Zwierlein says this experiment can be used to work out the resonant frequencies at the centre of a neutron star. Theory suggests that the cores of neutron stars contain strongly intera...
