A force is a push or a pull that acts on an object due to the interaction with another object. Force is measured in newtons (N). Forces are divided into contact forces and non-contact forces. A force ...

July 3, 2026 Researchers have created quantum control techniques that can make a system appear to run backward in time. By precisely managing quantum measurements, they can reshape the system's arrow ...

Quantum physics is the study of matter and energy at its most fundamental level. A central tenet of quantum physics is that energy comes in indivisible packets called quanta. Quanta behave very ...

There has never been a more exciting time to study the exciting discipline of physics, spanning the workings of the sub-atomic world to the ever-expanding universe. The BS Physics Program in the ...

The Martin A. Fisher School of Physics enjoys an international reputation for excellence in research, and is one of the highest-ranked of its size in the country. The department offers rigorous ...

Matter is made up of small particles called atoms. Atoms can exist on their own or together as molecules. Atoms are very small and around 100,000,000 of them end to end would measure 1 centimetre.
