My Math Blog Statistics, August 2014

So, August 2014: it’s been a month that brought some interesting threads into my writing here. It’s also had slightly longer gaps in my writing than I quite like, because I’d just not had the time to do as much writing as I hoped. 515 more words


Q: Of the 20 students in the classroom, 14 are taking Calculus, 12 are taking Physics, and 4 are taking neither Calculus nor Physics. How many students are taking both Calculus and Physics? 93 more words


Venn will we use this Miss?

Now that Sets and Venn Diagrams are back on the syllabus at KS4, how do we go about teaching it? 889 more words

180 Years of Venn

In my family, we were rather casual about birthdays and other event days. It wasn’t  unusual to celebrate a birthday, not on the exact day, but on a nearby day. 971 more words

Let's Draw Some Venn Diagrams!

Google Doodle today, August 4th 2014, marks 180th birthday of John Venn, the man who gave us Venn Diagrams (http://www.google.com/doodles/john-venns-180th-birthday). Anyone who has ever taken any course in statistics knows Venn Diagrams, probably as the most interesting thing they learned in the class. 152 more words


In the Overlap between Logic, Fun, and Information

John Venn, an English philosopher who spent much of his career at Cambridge, died in 1923, but if he were alive today he would totally be dead, as it is his 180th birthday. 88 more words

Joseph Nebus reblogged this on nebusresearch and commented:

Since I do need to make up for my former ignorance of John Venn's diagrams and how to use them, let me join in what looks early on like a massive Internet swarm of mentions of Venn. The Daily Nous, a philosophy-news blog, was my first hint that anything interesting was going on (as my love is a philosopher and is much more in tune with the profession than I am with mathematics), and I appreciate the way they describe Venn's interesting properties. (Also, for me at least, that page recommends I read Dungeons and Dragons and Derrida, itself pointing to an installment of philosophy-based web comic Existentialist Comics, so you get a sense of how things go over there.)


And then a friend retweeted the above cartoon (available as T-shirt or hoodie), which does indeed parse as a Venn diagram if you take the left circle as representing ``things with flat tails playing guitar-like instruments'' and the right circle as representing ``things with duck bills playing keyboard-like instruments''. Remember --- my love is ``very picky'' about Venn diagram jokes --- the intersection in a Venn diagram is not a blend of the things in the two contributing circles, but is rather, properly, something which belongs to both the groups of things.


The 4th of is also William Rowan Hamilton's birthday. He's known for the discovery of quaternions, which are kind of to complex-valued numbers what complex-valued numbers are to the reals, but they're harder to make a fun Google Doodle about. Quaternions are a pretty good way of representing rotations in a three-dimensional space, but that just looks like rotating stuff on the computer screen.
