TED-Ed: What’s a squillo, and why do opera singers need it?
An orchestra fills an opera house with music, but a singer’s voice soars above the instruments. Its melody rings out across thousands of patrons— all without any assistance from a microphone. How is it possible that a single voice can be...

TED-ED: How do we study living brains? - John Borghi and Elizabeth Waters
As far as we know, there's only one thing in our solar system sophisticated enough to study itself: the human brain. But this self-investigation is challenging because a living brain is shielded by skull, swaddled in tissue, and made up...

Wavelength
In this video Paul Andersen explains how the wavelength is the distance between oscillations in a wave. In a longitudinal wave this might be the distance between areas of compression. In a transverse wave it might be the distance between...

The Cosmic Lasers That Form in Outer Space
Lasers are incredible narrow beams of light we can use to do everything from cutting metal to operating on people's eyeballs. But even though we came up with the idea on our own, humans didn’t actually make the first lasers.

Hearing & Balance: Crash Course A&P
Crash Course A&P continues the journey through sensory systems with a look at how your sense of hearing works. We follow sounds as they work there way into the ear where they are registered and transformed into action potentials. This...

Matter as a Wave
In this video Paul Andersen explains how matter can act as a wave at the nanoscale. Louis de Broglie showed that the wavelength of matter can be calculated using the momentum of an object and Planck's constant. The Davisson-Germer...

TED-ED: The sonic boom problem - Katerina Kaouri
Objects that fly faster than the speed of sound (like really fast planes) create a shock wave accompanied by a thunder-like noise: the sonic boom. These epic sounds can cause distress to people and animals and even damage nearby...

Pilot Wave Theory and Quantum Realism
There are some pretty out-there explanations for the processes at work behind the incredibly successful mathematics of quantum mechanics - things are both waves and particles at the same time, the act of observation defines reality, cats...

Why Don't Whales Deafen Themselves?
Whales have a lot of the same ear parts as humans, but they are capable of making sounds that could easily shatter a human's eardrums. So why are they seemingly immune from their own sense-shattering sounds?

When Quasars When Quasars Collide STJC
In this video, we discuss the reports about the detection of a pair of supermassive black holes orbiting only one light year apart from each other. Studying the dance of these giants should tell us a ton about how black holes grow.

Why Can't We Get Power From Waves?
Wave power hasn’t yet made a splash because it’s hard to use waves to spin turbines, and because the sea is a harsh place to build things. ___________________________________________ To learn more, start your googling with these...
