To detect the quantum friction of empty space, scientists are going for a spin. A twirling nanoparticle, suspended in a laser beam inside of a vacuum, can measure tiny twisting forces, making it the ...

Our data-driven world demands more—more capacity, more efficiency, more computing power. To meet society's insatiable need for electronic speed, physicists have been pushing the burgeoning field of ...

If you've ever tried to understand the difference between horsepower and torque, you've likely come across this silly ...

Many natural processes, ranging from magnetism to chemical reactions, entail the movement and rotation of particles at very ...

In this episode of Crash Course Physics, Shini sits down with us to discuss what torque is, how it works, why it works, and what it all has to do with this thing called "Moment of Inertia." And a ...

Escherichia coli bacteria are the workhorse of microbiology labs. These bacteria move through fluids by spinning their flagella — a clump of tails driven by a molecular motor in the cell walls.
