I had to vacuum the Den and the master bath before I figured it out! Solution below the fold. To clarify a bit. Each of the four shapes has one value (positive integers). The numbers in each of the eight figures are the sum of the shape’s value PLUS the values of the shape(s) it
It’s really getting green out everywhere out there! Well, except for what’s covered with pine pollen. Last day on the Mathematics and Logic course. Things are going well. Learned a lot.
is impossible. You can square pretty much all other shapes, even lunes (crescents) but you cannot square a circle because our old friend pi is a transcendental number. Now you know. And now I will return to a project I began earlier this morning. Trust me when I tell you that the folk who are
We’ve been dealing with the aftermath of last month’s cold. I will not go into detail but the following words will give you a clue. Lake. Frozen. Ice. Deer. Thirst. 5-degrees. Deersicle. 70-degrees. Floating. Stink. Waiting. For. Buzzards. And I just now wondered how the Beavers managed. I’m sure they were altogether cozy warm in
sure were smart. This is a fun course. Good exercise for the old neurons. I especially like the proof showing that the square root of 2 is an irrational number. And I will be honest and tell you that I was stopped dead in my note taking when it hit me. I wrote: RATIO RATIONAL
I started taking a Hillsdale College online course, Mathematics and Logic: From Euclid to Modern Geometry. The second lecture ended with a puzzle from Lewis Carroll. Everyone who is sane can do logic. No lunatics are fit to serve on a jury. None of your sons can do logic. The puzzle to to views your
Toward a Logic of Historical Thought David Hackett Fischer (1970) People write histories. Writers (often) commit fallacies. People read histories. [Normative statement coming up.] Readers should read critically. Readers familiar with writers’ fallacies are better critics. I’m not a logician and that’s not a good argument (?) but you get the gist. So we are
For the City Mice who have no idea what you’re looking at, I shall explain. These stumps are evidence of beavers. Using their rather large incisors, they have ‘chopped’ down a whole bunch of trees and have dragged them to the location of their lodge. These are actually rather small sized trees– I’ve seen much
“The turkey vulture not only acts but looks as if it had been born in a garbage can and doused with slop and ashes.” American Wildlife Illustrated (1953) These are black vultures, which are described as “another unbeautiful bird.” Little known fact, vultures are protected by law because they are migratory birds. In some regions,
I am at a meeting of the Southern Society for Philosophy and Psychology (SSPP). This particular session is on Neural Tools. I was going to skip the first talk but I’m glad I didn’t. The image is of the inside of a cell, taken with some fancy crystallography tool. Beautiful, isn’t it? If you remember
Chat with some famous… [checks email] Japanese neuroscientist coming up shortly. Need to buy a new television. Feel as if I need to look forward to something being delivered to day but cannot remember what. Listened to Dvořák’s New World Symphony last evening. That was nice.
Looks as if it must have been delivered to E. 5th St. at least twice if not three times. Arrived at E. 10th St. today. Miss M advises me to put the apartment # on separate line. No idea who lives at 2505 E. 5th St. but it was nice of them to not just
So this is how I compromised: That pic of a slide rule is gone. I can do much better. In the read through of The Companion Book Mr. Big Food took exception to my exposition of how slide rules work. And I did not want to omit talk of logarithms. so this is what I
Late yesterday afternoon I thought I had finished The Companion Book. The Prairie voles were a struggle. Access to the Mississippi State Library requires that some algorithm sends Mr. Big Food’s phone a push– whatever that is… blah blah blah. The 1978 paper I needed and searched for is only in the stacks. That was
In the next book, which is currently being written in my brain, Miss Missy’s School will take a field trip to Rainwater Observatory in French Camp, Mississippi. The question is, which of these two programs should we request? There are telescopes under the domes!
