A complex chart consisting of dates, page numbers, topics, etc. that math and science teachers enjoy making you do. Your teacher will harp at you to write down the table of contents every day and threaten your grade if you don't. It is intended to be useful, but for the most part, it's not.
Teacher, glaring at your paper: Have you done the table of contents for today?
You: N-n-no?
Teacher: *eyebrows raise* You have to do the table of contents every day! Minus 10 classwork points.
The Wadsworth Constant is the fundamental idea that the true meaning of a video, conversation, or comment approaches importance after approximately 30% of it has been skipped over.

"the true meaning of a video, conversation, or comment approaches importance after approximately 30% of it has been skipped over."
The Karpathy constant is one of the best learning rates for the popular Adam (deep neural network) optimizer. It is defined as η = 3e-4. The actual symbol for the constant is α_k.
The result when summing all the divisors of the numbers from 1 to 9. Seems to be a fundamental constant of nature, since it occurs many times on the Internet.
