8:43 PM | Red Nose Collection
Comic Relief is nearly upon us once more; the extraordinary British charity event that results in the biennial reinvention of the red nose. Every two years you can either fork out for a new ruddy conk or throw caution to the wind and reach down the back of your sofa to find the one from last time. And some peanuts. And something that used to be less slimy.This year, there are nine of the handsome little hooters to choose from.Stripey, Astrosnort, Supernose,Snotty Professor, Nosebot, […]

8:28 PM | Normalized Frequency For The Win
Frequency response plots are often shown with normalized frequency on the X-axis. This sometimes confuses people. The normalized frequency is computed by dividing the true frequency by the sample rate. Hence, the sample rate itself has… Tags: Signal Processing

3:00 AM | The Stable Marriage Problem (Gale-Shapley Algorithm) – An Algorithm Recognized In the 2012 Nobel Prize And Used In The Residency Match
I’ve been meaning to post about this for a while now, especially after the 2012 Nobel Prize went to Alvin Roth and Lloyd Shapley for work in matching markets. I have made a video that illustrates the Gale-Shapley algorithm and hopefully introduces many people to this wonderful part of game theory. The Stable Marriage Problem […]

4:46 PM | Wolfram|Alpha can’t. But CP can!
. @christianp has turned into a one-man plug for the holes in Wolfram Alpha. I’m genuinely impressed. — Colin Beveridge (@icecolbeveridge) February 28, 2015 For a while, I’ve been following this cool Twitter account that tweets questions Wolfram|Alpha can’t answer. The genius of it is that the questions all look like things that you could half-imagine... Read more »

6:00 AM | (x, why?) Mini: Septagon
(Click on the comic if you can't see the full image.) (C)Copyright 2015, C. Burke.I think the only reason Septagon, as in September, isn't used is because then we'd have to use Sexagon for six-sided. This leads to misunderstandings with Sexy Primes, of course. Sadly, there are no Septy Primes

3:00 AM | Solution to Divide Into 4 Equal Parts
Last week I asked you to divide a trapezoid into 4 equal parts with 4 equal pieces. There’s a neat trick on how you can do this: you can tile the same shape to re-create the original! (Click to see image of solution) It’s a pretty neat trick that can sometimes work in other dissection […]

3:00 AM | Monday Puzzle: The 15 Puzzle
Sliding block puzzles were a part of my childhood. The puzzle involved moving blocks using the “free space” until you assembled the pieces to re-create a picture. This toy seems pretty boring today, but at one point there was a huge craze about them. In the 1880s, the 15 puzzle was as big as more […]

maxwellsequations:#tbt I decided last night that this is probably my all-time favorite page of notes of mine because while I’m p sure I got some things wrong, I was on the right track. And, I dunno, it’s got some kind of page of notes “it” factor to me.Early 2013, I was in Honors Calc III, diffy q, Intro Astro II, and I think some gen eds or something. Ha, first A(+/-) in a math class in my entire life was in Honors Calc III with Brodskiy, who rules fwiw. I loved that class so gd much.

12:45 PM | Black Swans…
Today's Sunday reflection comes from the "Prologue" to Nassim Taleb's "The Black Swan": "Before the discovery of Australia, people in the Old World were convinced that all swans were white, an unassailable belief as it seemed completely confirmed by empirical evidence. The sighting of the first black swan might have been an interesting surprise for a few ornithologists… but that is not where

12:00 PM | Richard Elwes.... Writing Maths For the Masses
 Math-Frolic Interview #28                 "...it's time to slay some ghosts and kill some prejudices. Let's admit that any field of human endeavor worth investigating eventually gets to a level of technicality that becomes challenging, and it's fair to say that many people hit that ceiling earlier in mathematics before they do in other, perhaps more verbal, subjects. But before that level

3:23 AM | On An Arithmetical Pursuit - student
Whilst taking our afternoon tea, my fellow students and I occasionally pass the time with some arithmetical pursuit, being a game in which the goal is to be the swiftest to manipulate six randomly chosen integers with addition, subtraction, multiplication and division to hit a randomly chosen target, or at least to land as closely as possible to it, admitting no more than one appearance of each number and no fractions.
