Only certain people need a scientific dictionary.

It provides a lot of information for scientists. The term is used for a lot of different books. So many sciences require their own special volume. We'll examine a few.

One scientific dictionary is found on line. The name is Kimball's Biology Pages. It organizes information both alphabetically and via a search. The alphabetic list leads to many index pages each one about a different subject. Here's one.

The scientific dictionary has zygotene under the letter z. It's when cells separate into chromosomes. This only happens in some cells. The cell must be encased within a membrane.

This scientific dictionary contains the word chimera. Genetic mosaic is another name for it. It's when two early embryos combine into one. It happens within the human species too. The name comes from the Greek monster. It had a lion's head, a goat's body and a serpent's tail.

The scientific dictionary chimera is not the chimera of mythology. It was a native of Lycia in Asia minor. It was featured in the Iliad. This creature could also breathe fire. Some forms of the myth gave it three heads instead of just one.

The scientific dictionary doesn't mention the chimera's brother creature. It was called a Hydra. It too had many heads. Hercules faced one of them. When one head was cut off, two more would grow instantly in its place. Needless to say it was very difficult to kill.

Another scientific dictionary is one that contains information on math for kids. The online version includes interactive and animated displays. There's a lot of good knowledge to be gained from it. It covers the acute angle. Any angle less than 90° is acute. A cartoon pelican demonstrates the concept with its beak.

Another concept contained within this scientific dictionary is that of area. That's how much space something uses. To show this kids can drag various shapes over a grid and then count the number of squares taken up by the shape. It also shows different units both standard and metric.

The possibilities are endless. There is practically a scientific dictionary for every different subject under the sun.
