Did the NSA make a major math breakthrough?
From The Daily Dot: To date, there is no known shortcut to quickly factor large integers into primes. It has never been proven that no such shortcut exists. We’ve just never found one. If the unfactorable nature of these large integers doesn’t … Continue reading
Chaos Game
The chaos game, previously seen on Frank Noschese’s 180 blog and Jonathan Clayton’s blog Infinite Sums. I had to make this myself (deja vu?). Here’s what I made (processing 2.0): Check it out live. All these live links will probably … Continue reading

@fawnpnguyen whoa. Need to try and make this. — Dan Anderson (@dandersod) June 4, 2013 I started off and used VPython to create the fractal, but it was slow and buggy. Here’s a movie of my first attempt. When you … Continue reading
Calculate Pi with Python
Intro to Computer programming worked at calculating digits of pi today. The actual algorithms aren’t too bad, but getting more than the standard number of digits from a double is a bit trickier. Here’s a program that calculates pi using: Bailey–Borwein–Plouffe formula … Continue reading
Powers of 2 without a Zero
2^86 is largest known pwr of 2 that does not contain 0.What about other digits?Does each non-zero digit occur inf often among the pwrs of 2? — James Tanton (@jamestanton) March 6, 2013 Interesting. The Intro to Programming Students gave … Continue reading
Reducing Prime
Number theory nugget: 357686312646216567629137 is a prime number which remains prime after removing any number of digits from the left side! — Maths World UK (@MathsWorldUK) March 4, 2013 Otherwise known as left-truncating primes with every suffix prime and no … Continue reading
Bret Victor’s Learnable Programming
Bret Victor (Inventing on Principle) wrote an excellent essay on Learnable Programming. If you have any interest in how people learn computer programming best, or how people learn in general, then go read it. Now. Shoo. And you probably want to read … Continue reading
Move The Turtle (iOS)
Move The Turtle. The “game” portion of this app is pretty simple, but it comes with a programming interface which is very easy to get into. Fun stuff. After 10 minutes of tweaking:
