The comic depicts a relationship between how philosophically exciting the questions in a field of study are, versus how many years are required to understand the answers.  For example, {{w|special relativity}} poses very intriguing philosophical questions, such as "{{w|Relativity of simultaneity|can the temporal ordering of spatially separated events depend on the observer?}}", or "{{w|Twin paradox|can time run at different rates for different observers?}}".  But it doesn't take a lot of mathematical knowledge to understand the answers - that when objects move very close to the speed of light, {{w|time dilation|time slows down}} and their {{w|length contraction|lengths contract}}: the key {{w|Lorentz transformation}}s ultimately involve little more than high-school algebra. Hence, Special Relativity is very high up on the y-axis but not very far on the x-axis.  Basic physics is not very philosophically interesting but also not very complicated.  {{w|Fluid dynamics}}, as captured by the {{w|Navier–Stokes equations}} is very complicated, but it's concerned with a very specific topic - how water or other fluids flow around - so it doesn't lead to big philosophical questions.

The "danger zone" in the top right of the chart is when a field of study is wide-ranging enough to pose broad philosophical questions, and also so complicated that most people can't answer those questions.  {{w|Quantum mechanics}} deals with some very strange concepts that readily lend themselves to philosophical questions, such as the idea that merely observing something can change it, or the idea that something can be both a wave and a particle at the same time.  However, the explanation for those phenomena is a very complicated piece of math, notably the {{w|Schrödinger equation}}, which means that most people don't have accurate answers to those questions. [[Randall]] suggests that this is the reason why so many people have "weird ideas" about quantum mechanics.

[[1240: Quantum Mechanics]] also discusses weird ideas that people have about quantum mechanics.
