George William Hart (born 1955) is an American geometer. He is an interdepartmental research professor at the State University of New York in Stony Brook, New York and his work includes both academic and artistic approaches to mathematics.
His artistic work includes sculpture, computer images, toys (e.g. Zome) and puzzles. His sculptures have been featured in articles in The New York Times, Games, Science News, Science, Tiede (Finnish), Ars et Mathesis (Dutch), Наука и жизнь [failed verification] (Russian) and other publications around the world.
His academic work includes the online publication Encyclopedia of Polyhedra, the textbook Multidimensional Analysis, and the instruction book Zome Geometry. He has also published over sixty academic articles.
Hart is a co-founder of North America's only Museum of Mathematics, MoMath, in New York City. As chief of content, he set the "Math is Cool!" tone of the museum and spent five years designing original exhibits and workshop activities for it.
Hart is a coinventor on two US patents, U.S. Patent 4,672,555 Digital ac monitor and U.S. Patent 4,858,141 Non-intrusive appliance monitor apparatus. These patents cover, in part, an improved electrical meter for homes called nonintrusive load monitors. These meters track changes in voltage and current usage by a given household and then deduce which appliances are using how much electricity and when.

Incompatible Food Triad
The Incompatible Food Triad is a puzzle to find three foods for which any pair will taste good together, but all three together will not. The puzzle is believed to have originated with the philosopher Wilfrid Sellars, and has been spread by some of his former colleagues and students, including Nuel Belnap and George W. Hart. The puzzle was also featured on WNYC's The Brian Lehrer Show.
Given three foods that do not go together, it is usually because two of them don't go together. For example, Richard Feynman's famous example of accidentally requesting milk and lemon in his tea is not a solution. While tea and lemon do go together, and tea and milk do go together, milk and lemon do not go together. For this solution to work, milk and lemon would have to go together as well.
According to Hart, most attempted solutions tend to overlook one of the three pairs. Issues of personal taste and preparation complicate the issue, as combinations some consider acceptable sound unpalatable to others, and problems such as milk curdling with the addition of lemon juice can potentially be overcome if a cheesemaking process is employed.
In a posting on its website after the puzzle was aired on the WNYC radio show in New York; Beer, 7Up, and Whiskey was given as a solution with the statement that beer with 7Up makes shandy, beer with whiskey makes a boilermaker and whiskey with 7Up is a 7 & 7, but the three together would "make you sick". Other possible solutions from viewers included:
- pie crust, raspberries and spinach
- chocolate, peanut butter and chicken
- Conway polyhedron notation - Created propellor and reflect operations for his artwork.
