normal
Explanation
This comic is a math joke about the concept of "normal numbers" in mathematics.
The single panel shows a group of alarmed mathematicians staring at a computer screen. One announces: "See? Just around the 10 sextillionth digit it becomes 'stay away from the humans' over and over and over."
The caption reads: "The discovery that pi is non-normal was made in an especially disturbing way."
In mathematics, a "normal number" is one whose digits are uniformly distributed -- every possible sequence of digits appears with equal frequency. It is widely conjectured (but not proven) that pi is a normal number, meaning its digits are essentially random with no pattern favoring any particular sequence.
The joke imagines a scenario where mathematicians discover that pi is NOT normal -- its digits eventually settle into a repeating pattern. But the specific pattern is a message: "stay away from the humans," as if encoded into the fundamental mathematical constant by some cosmic intelligence warning others about humanity.
The humor operates on multiple levels: the mathematical concept of normality, the cosmic horror of discovering a message embedded in a universal constant, and the self-deprecating implication that any sufficiently advanced intelligence would warn others to avoid us. The disturbed expressions on the mathematicians' faces sell the joke -- they have not only disproved a major mathematical conjecture but also discovered that the universe itself contains a warning about their species.
