Published on Sunday, July 30, 2006 in , ,



Here is one of the weirder ways I've ever seen of solving the Rubik's Cube. C. J. Karr solves his cube while riding a bicycle! The camera operator is on a bicycle, also, so the solving itself can become impossible to see at some points, but it does make for some interesting and dynamic shots.

Chris Hardwick, whose blinfolded Rubik's Cube videos I've referenced here and here, has posted some more interesting videos.

In these videos, Chris is solving the cube one-handed. First, there's a 44.98 second one-handed solution, followed by a 29.09 second one-handed solution! This is even faster than the Dave Campbell video I posted just two days ago!

Judging by the number of one-handed Rubik's Cube solving videos on YouTube, this form of challenge is becoming more and more popular!

Triangular Peg Solitaire

Published on Monday, July 10, 2006 in



Triangular Peg Solitaire is a simple, classic puzzle that still has the power to confound. If you're not familiar with it, or it doesn't seem that difficult, try it for yourself (Javascript required).

In the above video, you see “Kenny” solving the puzzle at a Cracker Barrel in Pennsylvania.

Update (1/16/07):Toby” can also solve the Triangular Peg Solitaire puzzle. “Thea”, after a few false starts, manages to solve the puzzle, as well.

Arthur Benjamin: Mathemagics

Published on Sunday, July 09, 2006 in , , ,



In my previous entry concerning Dr. Arthur Benjamin, I mentioned that I'd like to find his Mathemagics lecture. It's now been posted over on YouTube!

The complete lecture itself teaches how to improve your mental calculation skills, and is very clearly taught. These videos also came with audio tapes and a workbook, which are referred to in the videos. It's not hard to make up your own sample problems, however.

The above video is only the first of 11 parts. Here's an index for the complete set of Mathemagic video clips:

Part 1: Introduction, Adding 2- and 3-digit numbers
Part 2: Adding 2- and 3-digit numbers, Calculating tips, Subtracting 2- and 3-digit numbers
Part 3: Subtracting 2- and 3-digit numbers
Part 4: Subtracting 2- and 3-digit numbers, Multiplying 2- and 3-digit numbers by 1-digit numbers
Part 5: Multiplying 3-digit numbers by 1-digit numbers, Percentages, Division of 2- and 3-digit numbers by 1-digit numbers
Part 6: Division of 3-digit numbers by 1-digit numbers
Part 7: Multiplying fractions
Part 8: Multiplying, Adding and subtracting fractions, Converting fractions to decimals
Part 9: Converting fractions to decimals, Estimation, Squaring
Part 10: Squaring, Algebra
Part 11: Algebra, Fibonacci addition trick

Towards the end, there are a few times you are referred to the workbook for a more detailed explanation. Here are some links on the web that can give you the required explanations:

Converting fractions to decimals
The 1089 trick
How did Dr. Benjamin predict the result of digit #11 divided by digit #10?
