Cakewalk: On questions it can handle–especially computable ones in math, science, and engineering–Wolfram Alpha performs many original tricks. Presented with pancake ingredients (1), the engine offers possible variations (2), shows how it interpreted the input (3), and produces a combined nutrition label (4). Behind the scenes, Wolfram’s Mathematica software first performs any needed unit conversions (for example, converting “pinch of salt” to a computation-ready “380 milligrams of salt”). But an offer of “source information” (5) doesn’t trace facts to specific references.
