Pro Tip 1/3Small but Mighty
In physics, 'quantum' suggests something extremely small yet fundamentally crucial.
Atoms are composed of quanta.
Pro Tip 2/3Discrete Units
'Quantum' refers to fixed, distinct levels or amounts in scientific contexts, not continuous.
Electron transitions happen in quantum steps.
Pro Tip 3/3Technical Term
Used mainly in technical or scientific fields, not regular conversation.
Quantum computing will revolutionize technology.

most importantly, its wavelength, which is the distance between two neighboring peaks, or two neighboring valleys. But we can't assign it a single position. It has a good probability of being in lots of different places. Wavelength is essential for quantum physics

The Uncertainty...
Perhaps he has an opinion on the matter. Ha ha. Very amusing. Albert, the uncertainty principle works. It functions, and it allows us to make use of the quantum world. The goal of scientific pursuit should not be merely to make use of the world around us.

It's no longer a solid, a liquid or a gas. It enters a new state of matter called a superfluid. The atoms lose their individual identity, and the rules from the quantum world take over, and that's what gives superfluids such spooky properties.

The everyday world you know and love behaves according to the laws of classical mechanics. But systems on the scale of atoms behave according to the laws of quantum mechanics. This quantum world turns out to be a very strange place.

because there's still so much we don't understand about the universe. Perhaps we'll find new exotic forms of matter that'll force us to revisit the laws of thermodynamics. Or maybe there's perpetual motion on tiny quantum scales.

Julia Sawalha
British Actress
I'm into the law of attraction and quantum physics. Like cosmic ordering. It's all about thinking lovely things that you would like in life, and feeling good about them before they manifest, so that by the time they do, you don't want them because you're on to your next desire.
Quote examples
Leonard Susskind
American Physicist
The most important single thing about string theory is that it's a highly mathematical theory, and the mathematics holds together in a very tight and consistent way. It contains in its basic structure both quantum mechanics and the theory of gravity. That's big news.

Ashoke Sen
Indian Physicist
In many ways, string theory attempts to go beyond Einstein's dream... an all-encompassing description of nature that works at large distances where gravity becomes important as well as small distances where quantum mechanics is important.

Francis Collins
American Scientist
I finished up my graduate degree in quantum mechanics, but underwent a bit of a personal crisis, recognizing that I didn't want to do that for the rest of my life. It was too abstract, too far removed from human concerns.

I come from a long line of below-stairs maids and gardeners. Good ol' peasant stock. My mother and her sister made a quantum leap out of that life. Then I made another quantum leap.

Life is strong and fragile. It's a paradox... It's both things, like quantum physics: It's a particle and a wave at the same time. It all exists all together.
