(Click on the comic if you can't see the full image.) (C)Copyright 2014, C. Burke.Happy 7th Birthday, (x, why?)! Back? After seven years and 921 comics (more or less), I'm not going anywhere! Funny thing about using song lyrics. Thanks to the Internet I can check on the lyrics I'm not sure about, and discover that the ones I've "known" since I was a kid aren't actually the words, but they've been stored that way. As for "Signs", I discovered that every site had one of two distinct sets of […]

intothecontinuum: (click through the images to view in high-res) Penrose tilings are an example of the non-periodic tilings discussed in the last post. Recall that these are tilings that cover the entire infinite plane leaving neither gaps nor overlaps. Whats nice about these tilings is that the set of tiles used to construct the Penrose tilings only consists of two different basic shapes consisting of quadrilaterals.  Whats even more remarkable about Penrose tilings is that using just […]

Here are some interesting facts about math!  Proof is left as an exercise for the reader. Part I contains numbers 1 through 10.  Stay tuned for Part II which will feature numbers 11 through 23! 1. If you write out pi to two decimal places, backwards it spells “pie”. 3.14=PIE 2. A French word for pie chart is “camembert”. Because of course it is. 3. The spiral shapes of sunflowers follow a Fibonacci sequence. That’s where you a [...]

Hard to believe that nearly seven years have passed since I started making these comics to pass the time and to keep my sanity. And then I started to lose a little sanity trying to keep to a schedule. So much so that I even had vacation strips running for a week! But (x, why?), which started on this blog and then migrated -- for better exposure, I guess -- to the Comic Genesis site, is having a 7th birthday, or it is an anniversary, on Friday. I guess it isn't too hard to believe that a […]

PhotoMath App I saw this interesting video while browsing Reddit today and I wanted some opinions on it. The video shows an app called PhotoMath. From PhotoMath’s site: PhotoMath reads and solves mathematical expressions by using the camera of your mobile device in real time. It makes math easy and simple by educating users how to solve math problems. The app does just give you the answer, so it might become a crutch to students. However, it is a useful tool like any calculator, and […]

discoverynews: King Tut Re-Creation Presents a Shocking Image Tutankhamun’s beautiful golden mask, the embodiment of a man secure in his power, has been flattering the pharaoh for many centuries, according to the most detailed image yet of the teenage king’s face and body. In the flesh, King Tut had a club foot, a pronounced overbite and girlish hips, says a “virtual autopsy” built using more than 2,000 computerized tomography (CT) scans of the pharaoh’s body.

fouriestseries: Curves of Constant Width and Odd-Sided Reuleaux Polygons A curve of constant width is a convex, two-dimensional shape that, when rotated inside a square, always makes contact with all four sides. A circle is the most obvious (but somewhat trivial) example. Some non-trivial examples are the odd-sided Reuleaux polygons — the first four of which are shown above. Since they don’t have fixed axes of rotation, curves of constant width (except the circle) have few practical […]

Here is a histogram of when people showed up to a party. From FiveThirtyEight, begun by Walt Hickey, but then crowdsourced from readers. Of 803 guest times submitted, the median guest arrived almost an hour after the party's start time. Four guests showed up over 3 hours late. How fashionable is that?They also looked at a scatterplot of arrival time against number of party guests.  They fit a regression, with only a 5%  R2, and the following interpretation: as host you should […]

All graphs come from Wolfram Alpha (very cool resource).

(Click on the comic if you can't see the full image.) (C)Copyright 2014, C. Burke.Why are planes always parallelograms? Doesn't that get confusing? I've wanted to do this every Sunday since the season started, and then I forget until the last minute ... so I say, "That's okay. There's Monday Night, too!", but that hasn't worked out recently, either. So here it is.
