Why is physics considered a math?
Because physics concentrates on the material world, it tests its theories through the process known as observation or experimentation. In theory, it may seem relatively easier to detect where physics leaves off and mathematics picks up. However, in reality, such a clean-cut distinction does not always exist. Hence, the gray areas in between physics and mathematics tend be called "mathematical physics."

Atomic Physics, Nuclear Physics, Relativistic Physics, and Quantum Physics are examples of modern Physics.
What is Modern Physics?
Modern Physics designates the new conceptions of Physics developed during the first three decades of the 20th century , which resulted from the theoretical propositions of physicists Einstein and Max Planck. After the emergence of the relativity of Einstein and the quantization of the electromagnetic waves, this new field of study has emerged, expanding the limited horizons of classical physics.
What is the general theory of relativity?
The relativity general is a generalization of the special theory of relativity, also developed by German physicist Albert Einstein. According to this theory, massive bodies, like planets and stars, are capable of deforming the weave, or the relief, of space-time . This deformation, in turn, gives rise to gravity.
Why does the gravitational lens occur?
The phenomenon of the gravitational lens occurs due to the distortion of space-time exerted by large masses , such as those of stars and planets. According to general relativity, proposed by Albert Einstein, the gravity exerted by massive bodies is the result of deformation in the space-time relief. As a result, when propagating through the deformed space-time, the light would suffer a deviation.
Who developed the photoelectric effect?
The photoelectric effect was a phenomenon without a satisfactory explanation until the studies developed by Albert Einstein. For explaining this effect, Einstein was awarded a Nobel Prize in Physics. Through Max Planck’s idea, Albert Einstein expanded the energy quantization theory of blackbody radiation to any type of radiation, thus establishing the notion of wave-particle duality.
