Molecular gastronomy is a hot topic burning up the culinary world. As with any controversy, the Rubinos are hooked by opposing views coming in from gastronomic purists and hypermodern cooks alike. The only way to really get to the heart of the matter is to jump right in. A fresh approach to demystifying the old school vs. new school battle leads the Rubinos to some of America's leaders in culinary science. In the end, only ones palette can be the true judge of any culinary creation and an expert panel is called in to assess the validity of the food science movement or to make it history.

Organic chemistry goes industrial with William Perkin exploring carbon's tetrahedral bonds and the discovery of chirality. This video looks at the concept of atoms as 3D objects and 3D structural diagrams and models. There is also a brief look at various synthetic organic compounds developed from natural ones, both achievements and difficulties.

Shows how carbon's structure allows it to be the backbone for macro molecules, and why starch and not cellulose is digestible by humans. Further sections show the extreme non-organic case of diamonds and the discovery of nitrocellulose and its importance; give the definitions of thermoplastics, thermosets, and glass transition temperature; and look at celluloid, bakelite, and nylon.
