A Low carb Calculator to find unlisted carbs based on a food products nurtrition label. It works by using the formula Calories = (Fat X 9) + (Carbohydrate X 4) + (Protein X 4) . Note that this formula is not perfectly exact, but an approximation. The program takes the difference between the stated calories and actual calories and divides by 4 to yield grams, and then adds that to the Carbohydrate grams listed on the label.

Produces stereoscopic graphs of mathematical functions or of approximations to their 1st and 2nd order partial derivatives. Most people are able to view these stereographs without any paraphernalia and feel a true three-dimensional effect. True depth perception is due to binocular vision and the Stereographer does provide this fascinating 3-D sensation. You can rotate and translate the surface or space curve, zoom in or out, pan, etc.

Classic games and challenging puzzles are fun for games lovers. Classic Pythagorean Puzzles is the best variation of tile-based antique Greek games offered by Pythagoras as an excellent brain trainer for abstract thinking. When you start new game you see a sample you need to replicate with the fixed set of tiles on the game board. The samples you replicate are being approximations of real objects, which are easily to recognize by shapes.
