Even More Quick Snippets

Luc Viatour's plasma lamp pictureApril's editions of snippets is dedicated to math and videos, so let's get started right away!

• Many people originally knew Danica McKellar as Winnie from The Wonder Years, and now know her as the author of several books designed to make math less intimidating for girls. Ever wonder how that change came about? In her brand new blog, she answers that question in her Why Math? post. Between that, her current roles, and her baby boy Draco, she's been keeping pretty busy:

• One of the newest items in the Grey Matters Store is my original 2011 Dice Calendar iPad, iPod Touch, and iPhone cases. The dice part is easy to understand, but the calendar part is hidden as part of the design. Here's the explanation:

Scam School recently delivered two podcasts that dealt with math somewhat indirectly. By that, I mean that the focus is on numbers and patterns instead of equations. Try and see if you can work out the answers for yourself before getting the answers:

The first of these two podcasts is called Petals Around The Rose, which I originally brought up in their forums:

The other one concerns a trio of number puzzles:

• During their 1941 movie, In The Navy, Abbott and Costello present a comedy routine in which Costello keeps showing that 28 ÷ 7 = 13:

10 years later, Marjorie Main and Percy Kilbride would perform a similar routine in Ma and Pa Kettle Back on the Farm. Only this time, the proof was that 25 ÷ 5 = 14:

This routine originated in the 1921 musical Shuffle Along, written by Flournoy Miller and Aubrey Lyles. This routine was still going around in 1972, when Flip Wilson performed the former version with Michael Jackson! Olivette Miller Darby, who was Miller's daughter, saw the routine and sued Flip Wilson for unauthorized use of the material.

Even though the math itself isn't exactly sound, here's some food for thought: Assume that there are always a single 1-digit number and two 2-digit numbers involved, what other sets of numbers could be used in such a routine? I'll give the answer in Thursday's post.
