“Quantum” originates from quantum mechanics, a branch of physics that deals with the behavior of particles at the smallest scales, such as atoms and subatomic particles. In physics, “quantum” refers to discrete units or packets of energy or matter. It suggests that certain physical properties, like energy, exist in discrete, tiny amounts, rather than being continuous. Quantum mechanics describes the behavior of matter and energy on the atomic and subatomic levels, often leading to phenomena that seem counterintuitive compared to classical physics.

**Quantum Quotes**

1. “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.”

**— Joan Jett**

2. “Quantum physics thus reveals a basic oneness of the universe.”

**— Erwin Schrodinger**

3. “Trying to understand the way nature works involves a most terrible test of human reasoning ability. It involves subtle trickery, beautiful tightropes of logic on which one has to walk in order not to make a mistake in predicting what will happen. The quantum mechanical and the relativity ideas are examples of this.”

**— Richard P. Feynman**

4. “We are the product of quantum fluctuations in the very early universe.”

**— Stephen Hawking**

5. “The uncertainty principle refers to the degree of indeterminateness in the possible present knowledge of the simultaneous values of various quantities with which the quantum theory deals; it does not restrict, for example, the exactness of a position measurement alone or a velocity measurement alone.”

**— Werner Heisenberg**

6. “Physics is really figuring out how to discover new things that are counterintuitive, like quantum mechanics. It’s really counterintuitive.”

**— Elon Musk**

7. “I became an atheist because, as a graduate student studying quantum physics, life seemed to be reducible to second-order differential equations. Mathematics, chemistry and physics had it all. And I didn’t see any need to go beyond that.”

**— Francis Collins**

8. “Until computers and robots make quantum advances, they basically remain adding machines: capable only of doing things in which all the variables are controlled and predictable.”

**— Michio Kaku**

9. “Readers probably haven’t heard much about it yet, but they will. Quantum technology turns ordinary reality upside down.”

**— Julie Andrews**

12. “Feynman once said, ‘Science is imagination in a straitjacket.’ It is ironic that in the case of quantum mechanics, the people without the straitjackets are generally the nuts.”

**— Lawrence M. Krauss**

13. “The development of quantum mechanics early in the twentieth century obliged physicists to change radically the concepts they used to describe the world.”

**— Alain Aspect**

14. “The quantum world is still very mysterious, still seemingly very powerful, and I’m definitely attracted to the mysterious and the unknown and just the vastness of what my imagination puts on it.”

**— Van Hunt**

15. “When you look at the calculation, it’s amazing that every time you try to prove or disprove time travel, you’ve pushed Einstein’s theory to the very limits where quantum effects must dominate. That’s telling us that you really need a theory of everything to resolve this question. And the only candidate is string theory.”

**— Michio Kaku**

16. “The verbal interpretation, on the other hand, i.e. the metaphysics of quantum physics, is on far less solid ground. In fact, in more than forty years physicists have not been able to provide a clear metaphysical model.”

**— Erwin Schrodinger**

17. “If someone says that he can think or talk about quantum physics without becoming dizzy, that shows only that he has not understood anything whatever about it.”

**— Frank Dukes**

20. “Old Newtonian physics claimed that things have an objective reality separate from our perception of them. Quantum physics, and particularly Heisenberg’s Uncertainty Principle, reveal that, as our perception of an object changes, the object itself literally changes.”

**— Marianne Williamson**

21. “It is often stated that of all the theories proposed in this century, the silliest is quantum theory. In fact, some say that the only thing that quantum theory has going for it is that it is unquestionably correct.”

**— Michio Kaku**

22. “The most important application of quantum computing in the future is likely to be a computer simulation of quantum systems, because that’s an application where we know for sure that quantum systems in general cannot be efficiently simulated on a classical computer.”

**— David Deutsch**

23. “Amplifying atoms is more subtle than amplifying electromagnetic waves because atoms can only change their quantum state and cannot be created. Therefore, even if one could amplify gold atoms, one would not realize the dreams of medieval alchemy.”

**— John Polkinghorne**

27. “There does seem to be a sense in which physics has gone beyond what human intuition can understand. We shouldn’t be too surprised about that because we’re evolved to understand things that move at a medium pace at a medium scale. We can’t cope with the very tiny scale of quantum physics or the very large scale of relativity.”

28. “I’m fascinated with quantum physics.”

**— will.i.am**
