Start with a square with length 1; label it R1.
Create a new rectangle as follows: attach a rectangle of area 1 to the right side and then attach a rectangle of area 1 to the top side. The border of this shape is a new rectangle, R2. Starting with R2, we can attach another pair of rectangles of area 1 to form a new rectangle, R3. From Rn – 1, attach a rectangle of area 1 to the right side, and then a rectangle of area 1 to the top. The border of this shape is rectangle Rn. The problem is: what is the ratio of the length, Ln, to the width, Wn as n goes to infinity? Watch the video for a solution.

Avoiding The Troll – Sunday Puzzle – Mind Your Decisions. Every day you make a trip from A to B, 2 miles away.
But your trip is unpredictable. On 50% of the days, you can walk between A and B without any obstruction. The other 50% of the time, a troll appears at the halfway point, blocking your trip. The troll also activates an invisible barrier that blocks 1 mile perpendicularly in both directions, forcing you to walk around it to complete your trip. You cannot see the troll or the barrier until you are halfway from A to B, so you cannot plan in advance whether you need to walk around the barrier.
If you can walk in straight lines to any points between A and B, what is your best strategy so you walk the least distance on average? Watch the video for an answer.

Euclid’s Elements form one of the most beautiful and influential works of science in the history of humankind. Its beauty lies in its logical development of geometry and other branches of mathematics. It has influenced all branches of science but none so much as mathematics and the exact sciences. The Elements have been studied 24 centuries in many languages starting, of course, in the original Greek, then in Arabic, Latin, and many modern languages. I'm creating this version of Euclid’s Elements for a couple of reasons.
The main one is to rekindle an interest in the Elements, and the web is a great way to do that. ▪ Τρία κλάσματα.
