Grade school teachers love to emphasize this concept to students, but it takes adult perspective to realize it’s true: Math is at the root of just about everything a person does. Sure, you can use an app to calculate the tip, but it’s so much cooler if you can do it in your head. Arizona Science Center’s “MathAlive!” shows that there’s more to math than playing Tetris on your smart phone. The interactive exhibit explores practical applications of the subject through its presence in video games and robotics, as well as fashion and music. Museum guests can exercise their mathematical prowess by building a bridge, making movies, and mixing a song.
