Richard P. Feynman

We get the exciting result that the total energy of the universe is zero. Why this should be so is one of the great mysteries - and therefore one of the important questions of physics. After all, what would be the use of studying physics if the mysteries were not the most important things to investigate?

Fundamental physics is like an art more or less. It's completely non-practical, and you can't use it for anything. But it's about the universe and how the world came into being. It's very remote from your daily life and mine, and yet it defines us as human beings.

I had a project for my life which involved 10 years of wandering, then some years of medical studies and, if any time was left, the great adventure of physics.

Werner Heisenberg

I had imagined doing nuclear physics and cosmic ray work in greater style in peace time. To do modern physics in a small way is of no use of all.

German Physicist

Stephen Hawking

I hope I have helped to raise the profile of science and to show that physics is not a mystery but can be understood by ordinary people.

I chose to pursue a career in physics because there the truth isn't so easily bent.

Laws of physics don't necessarily apply to real-life political situations.

Space, the whole universe - I know no better place to find new physics.

Nuclear physics is interesting but it is unlikely to help society.

I want to try to do something for women in physics worldwide.

Physics is a scientific field, often studied in educational settings and associated with experiments and theories.

Academic Subject

Physics has many branches, like quantum physics or astrophysics, focusing on different phenomena.

Branches of Physics

Physics can be very practical; it explains how things work, from roller coasters to smartphones.

Not Just Theoretical

When talking about physics in this context, think of how principles apply to real-life situations or products.

Real-world Applications

Physics engines are software that simulates physical systems in video games and simulations.

Technology & Software

Physics might be used in conversation to describe something as being very reliable or behaving as expected.

 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 because an object's wavelength is related to its momentum,

 is much different than the physics of the macroscopic objects you see around you all the time. 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.

 There's a concept that's crucial to chemistry and physics. It helps explain why physical processes go one way and not the why ice melts, why cream spreads in coffee, why air leaks out of a punctured tire.
