Physics is the scientific study of how the universe works in terms of its fundamental constituents, its motion and behaviour through space and time. All this is done through studying the entities of energy, gravity, force, pressure, electricity, magnetism, etc. This fascinating study makes it possible to understand how we are able to walk on a road but not on water, how a ballpoint pen works, how the sound waves that we generate into a microphone are amplified, why stars twinkle, and so much more. To know of all these and other interesting concepts of physics, we have for you a wide range of topics from the fields of astronomy, atomic physics, biophysics, electronics, environmental physics, machines, nuclear physics, optics and acoustics, etc. Browse through to spot something that catches your eye or search with specific key words to find what you need.
