Is it possible to create...
What we think of as subatomic particles, electrons and photons and their relatives, are actually vibrations in a quantum fabric that extends throughout the universe. And because of a physical law called the Heisenberg Principle, these fields never stop oscillating, even without any particles to set off the ripples.

Well, just about any calculations involving circles, from the volume of a can of soda to the orbits of satellites. And it's not just circles, either. Because it's also useful in studying curves, pi helps us understand periodic or oscillating systems like clocks, electromagnetic waves,

No matter how skilled a clockmaker may be, every pendulum, wind-up mechanism and quartz crystal resonates at a slightly different frequency. However, every cesium 133 atom in the universe oscillates at the same exact frequency. So thanks to the atomic clock,

a musical effect in which a note slightly oscillates in pitch. This creates a fuller sound that rings out over the instruments’ comparatively narrow vibratos. Once they have the right partials, they employ other techniques to boost their volume.

Is radiation dangerous?...
Electromagnetic radiation is pure energy consisting of interacting electrical and magnetic waves oscillating through space. As these waves oscillate faster, they scale up in energy. At the lower end of the spectrum, there's radio, infrared,

Coralline algae applies a kind of purple paint. The deepest red I've ever seen in my life lives underwater. Gorgonian fans oscillate with the waves.

Bel Powley
British Actress
Movies make teenagers have quippy answers for every question. Nothing seems to faze them, and they're like, 'Oh, whatever.' You're not like that when you're a teenager. You're really earnest. Things really feel like life or death. And you kind of oscillate between emotions at one time. It's very emotionally draining being a teenager.

Quote examples
Barbara Ehrenreich
American Writer
I routinely oscillate between exultation and despair. Maybe at the end of the day I feel pretty good about what I've written, but the next morning I see that it's crap. Then I start again - make a new outline, do some more research, try to rethink the whole question.

Quote examples
Sebastian Horsley
British Artist
Everyone says Oscar Wilde was a dandy, but he wasn't - he was an aesthete. He took pleasure in food and stuff like that. Dandyism is much more austere - much more Calvinistic, more neurotic - it oscillates between narcissism and neurosis.

Killian Scott
Irish Actor
Politics is real. It has an impact on people's lives. It's harder to quantify the impact art has. Personally, I oscillate between two extremes. Some days I think it's very important. Other days I think it isn't important at all.

I'm always oscillating between if I should sprinkle more gunpowder or less. But if I put too much gunpowder, there may be holes throughout the silk. If not enough, the power and energy would not be shown.

When you're a teenager, your essence is so specific to being a teenager, and everything becomes so extreme. Your emotions are on the surface, and you oscillate between different things at one time.
