Almost in the beginning was curiosity....There comes a point where the capacity to receive, store, and interpret message from the outside world may outrun sheer necessity. An organism may for the moment be sated with food, and there may, at the moment, be no danger in sight. What does it do then?....[The] higher organisms, at least, still show a strong instinct to explore the environment. Idle curiosity we may call it. ....The more advanced the brain, the greater the drive to explore....[Curiosity] for its simplest definition is "the desire to know."
Description:
- What is science?
- The Physical Science (The Universe, Earth, Atmosphere, Elements, Energy, etc.)
- The Biological Sciences (Molecules, Proteins, Cells, Microorganisms, The Body, The Mind, etc.)
- What separates humans from most other animals and drives science is curiosity, the "need to know" and to find answers;
- How to measure great distances, such as miles from the Earth to the Moon, to the Sun, to other planets, and far-flung stars as well as determine planetary and other astronomical orbits;
- With the naked eye, we can see about 6,000 stars on a clear night;
- Galileo's telescope showed for the first time that the Milky Way was composed of millions of stars and was flat-shaped;
- A light year is 5.88 trillion miles, i.e., 186,282 miles per second (the speed of light) x 31,536,00 (the number of seconds in a year);
- The unsolved question whether the universe is "evolutionary" (continually expanding and contracting), or whether it is "steady-state" (density of galaxies remains the same);
- A nova is not the death of a star but simply its sudden expansion (sometimes "a millionfold in less that a day") before settling back into its usual brightness;
- Clear explanations and examples of white dwarfs, red giants, super novas, comets, quasars, interstellar gas, dust clouds, telescopes, spectrum photography, radio waves, and so much more)
[N]o one can really feel at home in the modern world and judge the nature of its problems -- and possible solutions to those problems -- unless he has some intelligent notion of what science is up to. But beyond this, initiation into the magnificent world of science brings great esthetic satisfaction, inspiration to youth, fulfillment of the desire to know, and a deeper appreciation of the wonderful potentialities and achievements of the human mind.
Asimov, Isaac. Asimov's New Guide to Science.
Updated version (written 25 years later in 1984) of the original Guide to Science, and covers new discoveries in physics, robotics, biology, astronomy, computers, artificial intelligence, and other fields.
Happy reading.
