An Interesting Math Problem

Post by rkovars »

I didn't know where to stick this as it does pertain to time (well calendars at least). Being a math 'headed' person this was a really interesting video. I did pause the video where suggested and fell into the correct wrong answer trap. After the explanation it really makes sense and I found the ramifications to astronomical calculations fascinating. It is worth watching the whole thing.

I saw that, and my instinct was to select the most popular answer, also. No spoilers. Sidereal effects. Who knew?

Veritasium is brilliant. A couple of good ones.

Excellent video. I fell into the trap too, although I did do some contemplations that were along the lines of the real answer, but given that it was supposed to be solved in about a minute, my exam technique told me I must be going down the wrong path, so I turned back! Doh! #-o

That was fascinating!

Honestly, I can’t see how any student today could even solve that to get the wrong answer. Just getting the wrong answer involves a level of thought and logical analysis that I just can’t see 80% of students being able to do. It depresses me to say, but it’s true…at least where I teach.

I did feel like throwing a couple of quarters on the bar top and asking the question should get you a few free beers :lol:

I watched that last week and was (eventually) relieved to find that my initial answer, based on 2PiR was correct.... strange behavior depending on the point from which the rotation is viewed though.
