I enjoy the "Table Talk" Card Game that suddenly appeared on out dining room table. 52 Cards, each with a paragraph of information about a subject and then two questions about that subject.

Designed for children from 3 to 12, it is perfect for children from 65 to 99. One card was a brief biography of Mathematician and philosopher Rene Descartes. Most famous for the quote "I think, therefore I am." He also invented the Cartesian Co-ordinate system for measuring a flat plane mathematically. Graph Paper is often used... This is A very important idea especially in computer graphics. The BMP format for images assigns a pair of numbers to every PIXEL (Picture Element) and then assigns a COLOR to that location. Location is described using X and Y co-ordinates with X defining a Left-Right position and Y used for the Up-Down position. In Three Dimensional Space, there is a Z dimension as well, In-OUT... The JPG format for storing Images uses a different technique that allows a picture to be stored using much less data than BMP. The computer looks at a photo and determines How Many adjacent pixels have the same color. For example a portrait of a person standing in front of a clear blue sky has thousands of pixels of the same color, blue... So a JPG File would say something like, paint the entire top row (1,200 pixels) blue... then paint the next row blue... etc, etc, etc until it gets to a row that has the first 600 pixels blue and then the next 300 pixels brown and then the rest of the row blue... That would describe a row with a PERSON (brown) standing in front of a sky (blue).
