− | This | + | This comic is a joke on the common phrase "Shit just got ''real''", meaning that something has suddenly increased in difficulty so it is now a real challenge. [[Cueball]] is standing in front of a board delivering a lesson, and is about to multiply a wavefunction by its complex conjugate. In mathematics, a complex number has a real part (a) and an imaginary part (b*the {{w|imaginary unit}}). The number can be written as a+b{{i}}. The complex conjugate of a number (a+b{{i}}) is a–b{{i}}. When one multiplies a complex number and its conjugate, the result is (a+b{{i}})(a–b{{i}}), which is a<sup>2</sup>–(b{{i}})<sup>2</sup> = a<sup>2</sup>–b<sup>2</sup>{{i}}<sup>2</sup>. The imaginary unit {{i}} is defined as "the square root of –1", hence {{i}}<sup>2</sup>=–1. |
− | This | + | This process yields a result (of a<sup>2</sup>+b<sup>2</sup>) that does not have an imaginary part, making it a ''real'' number, which is a play on the aforementioned phrase. Accordingly, Cueball dictates that the people who are not skilled enough should leave. |
− | + | The title text states that if you joke about this every time it's applicable, that will be annoying enough that the class will ditch you and attempt to take place in another room. | |
