Physicists finally know where at least some of these high-energy particles come from, which helps make the neutrinos useful for exploring fundamental physics.
It seems impossible, but there’s a way to cool things off without tapping into a fuel source. (Hint: It involves outer space.)
Mathematicians can often figure out what happens as quantities grow infinitely large. What about when they are just a little big?
In the physics of water displacement, the answer isn’t always intuitive.
The line, from the Hindu sacred text the Bhagavad Gita, has come to define Robert Oppenheimer, but its meaning is more complex than many realize.
How much energy would it take to fuel a wave that you can shred like Kelly Slater? Here’s the math.
Electric vehicles are increasingly popular, so it’s time to talk about regenerative braking—and all the other ways you can stop a vehicle.
There’s a surprisingly straightforward answer to how many numbers are needed to fill an infinite grid so that identical numbers never get too close together.
