Ultimately, protons and electrons make the atoms about some elements, and atoms make the molecules that spell out a splendor in the rich variety of matter and life in the world.
They are too small to be perceived as separate entities by our naked eyes, and so large in their numbers we can hardly imagine them. A spoonful of water contains more atoms than there are stars in the universe. They are at the deepest roots of perceived reality.
We are not content with the experience of heat and cold. We want to know what exactly is the source of these sensations.
V. V. Raman’s magnum opus. In ten succinct chapters, he traces the development of Indian religion and philosophy from its distant origins to its most recent evolutions in an age of science. Comprehensive, scholarly, and eminently readable.
It is light that weaves the distant corners of the universe into a cosmic wholeness and that informs us of the presence of people and things beyond ourselves.
First, what is there in the external world that strikes us as sound? Second, what is happening in the internal world underneath the skull that creates this sensation?
We are immersed in seas of waves—not just of the light and sound that please our perceptions, but many more to which our senses don’t respond.

The box can be moved by giving it a push, and the cart by pulling it. We affect the motions of objects by imposing direct or indirect pushes and pull. Pushes and pulls are what we call forces.
Ours is not a static world like a dark dungeon where inert objects may lie immobile indefinitely. It is not a grand still-life, where mute matter stays scattered here and there, like boulders.
