NCERT books are considered the best source for clearing out the theoretical concepts and making the fundamentals strong. The questions and answers given in NCERT textbooks at the end of each chapter ...

It is something like the "Holy Grail" of physics: unifying particle physics and gravitation. The world of tiny particles is described extremely well by quantum theory, while the world of gravitation ...

Gravitation is a force by the virtue of which objects get attracted towards each other because they have mass. There are various laws and principles which govern this attractive force in the whole ...

For more than a century, gravity and quantum physics have stubbornly resisted a common language, one describing the smooth curvature of spacetime, the other the jittery statistics of particles and ...

Gravity is one of the four fundamental forces in the universe, alongside electromagnetism and the strong and weak nuclear forces. Despite being all-pervasive and important for keeping our feet from ...

[Translated by Dr. Robert W. Lawson.] MODERN physics renders it probable that the only fundamental forces in Nature are those which have their origin in gravitation and in the electromagnetic field.
