From the microchip to the laser, the 20th century was a pivotal point in the development of communications technology. But what does the 21st century have in store for us in the area of communications? "To understand the future, we should also look in the past, because that is where the future began," writes Anthony Wilson. The Internet, virtual reality, and even advances in home technologies and entertainment are discussed in this in-depth look at the future. Interesting text and more than 100 photographs bring you up-to-date on the most modern of inventions.
brain The main part of the nervous system in vertebrates that controls all body activities, such as breathing and walking. In humans, the brain is the center of speech, memory, thought, and feeling. The brain is protected by bones of the skull and is connected to the spinal cord.
The adult human brain weighs around 3 pounds and contains about 10 billion nerve cells. Each nerve cell is connected to about 10,000 other nerve cells, meaning there are 100 trillion nerve connections in the brain. The nerve cells are constantly sending signals to each other—a million times more signals per second than the world's fastest computers.
