As Russell said The word matter is, in philosophy, the name of a problem and our scientific investigations and philosophical inquiries show that it becomes more and more complex and interesting as we study it. This book seeks to show how ideas of matter have developed from Democritus to Heisenberg. The problem of matter may well be insoluble but at least we can begin to appreciate the mystery of what is so often taken to be the mundane 'stuff' of common sense.

The story behind one of the most significant technological wonders of the modern world that may change our understanding of matter and how the universe began.

This volume presents a basic overview of the human brain. The brain is the center of the nervous system in all vertebrate, and most invertebrate, animals. In vertebrates, the brain is located in the head, protected by the skull and close to the primary sensory apparatus of vision, hearing, balance, taste, and smell. This work contains a quick look at mankind's knowledge about the human brain throughout history. It also looks at human brain anatomy, the neurons, sensory perception, and the capacity for language, intelligence and creativity, memory, psychiatry, states of consciousness and sleep, as well as other rudimentary examinations of several medical aspects of neurology.

In the first fractions of a second after the Big Bang lingers a question at the heart of our very existence: why does the universe contain matter but almost no antimatter? The laws of physics tell us that equal amounts of matter and antimatter were produced in the early universe—but then something odd happened. Matter won out over antimatter; had it not, the universe today would be dark and barren. But how and when did this occur? In The Mystery of the Missing Antimatter, Helen Quinn and Yossi Nir guide readers into the very heart of this mystery—and along the way offer an exhilarating grand tour of cutting-edge physics.

Lily and Sam’s mother takes them to Prof Simplicius’ laboratory to learn about chemicals. While talking to the sharp and witty Professor, they come to know that the professor has misplaced an important formula he just invented. The only way to recover it is by learning more about the chemical matter. Through puzzles and puns the professor weaves interesting stories about chemicals present in air, water and things around us. He reminds the children that chemicals can be good or bad, but they are vital for our existence. Can Lily, a budding detective, apply this new found knowledge to solve the mystery and recover the precious formula?
