A Waste of 20 Minutes

The American Mathematical Monthly featured an article in January 2014, which reads as such:

"You spend 20 minutes telling them how wonderful it all is."
I'm sorry. It is wonderful how we can get around both the vertical line rule and the horizontal line rule
how the curve can flower, spiral, and cross itself again and again
how we can now make any pretty picture we want. Yes, it is all very wonderful but okay, I promise, I won't ever again waste 20 minutes.
And thank you for letting me in on the big secret, how to get through the syllabus: By not telling them how wonderful it all is.

In support of teachers around the world, what is a wonderful fact that your teacher has shared with you (instead of rushing through the syllabus)?

For me, it was seeing a proof of the Pythagorean Theorem when I was really young. I was amazed at how "it magically fit", and was surprised that there could be an equation like $a^2 + b^2 = c^2$ .

This discussion board is a place to discuss our Daily Challenges and the math and science related to those challenges. Explanations are more than just a solution — they should explain the steps and thinking strategies that you used to obtain the solution. Comments should further the discussion of math and science.

When posting on Brilliant:

Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.
Stay on topic — we're all here to learn more about math and science, not to hear about your favorite get-rich-quick scheme or current world events.

Thank you for this wonderful article :) i really wished my teachers have shared with me more fun facts and beautiful math when I was younger... Sigh...

In my school, I plan to set up a maths club where it entails different types of maths from different degrees such as looking into the Monty Hall Problem and different proofs such as this and dealing with the mathematical side of card tricks.

That's awesome. We should start collecting ideas here or on another thread for starting math clubs.

My junior-year high school physics teacher proof of Torricelli equation. He was the only one among all my teachers that actually explained where things came from.

$V_{F} ^2 = V_{O} ^2 + 2 a \Delta S$
