Euler and Venn diagrams are not really the same. For example, given the sets A={1}, B={2}, and C={3}
the Euler diagram would consist of 3 totally disjoint (non-overlapping) circles labelled A,B, and C. The Venn diagram would be the familiar 3 mutually overlapping circles with 5 of the 8 determined regions being empty.

If Steve reads this, my condolences on the less of Quincy. Losing pets is extremely sad. I'm thinking of you and your family!

Whoa, mispronouncing Euler. That is just awful. And Bob not even knowing who he is? Ouch.  :(

Sorry to hear about your dog.  We have a few in the garden that we miss.

I think Heaviside is pronounced heavy-side, based on Stephen Fry talking about the Heaviside layer, named after the same Oliver Heaviside.

I think you are right. I've had a few students who thought that the "Heaviside function" was the "Heavy Side function", and was a description of the appearance of the function's graph, not a name of a person.

2000 calories from glycogen is about what an elite marathon runner will use in a two hour race.  He/she will also will happily lose several kilos of water and finish the race up to 5kgs lighter than at the start; and will not be dehydrated, btw.  Last mile is the fastest mile.

Strava reckoned I "burnt" half of that on a casual road bike ride today.  I did refuel at 32 kms (after an 18 hour fast) with a flat white and a lamb burrito (yum), though.

How much glycogen would an elite marathon runner on a low carbohydrate/high fat ketogenic diet have? 

When I ran marathons (not at elite level, or anywhere close, my best time was 2 hours 47’), I used to carbohydrate load in the 3 days before, but I worked on the assumption that my glycogen stores wouldn’t last anywhere near to the end of the marathon, and that I’d eventually have to use fat stores (and in training, I attempted at times to carbohydrate deplete to get used to running on fat).

I don’t think you burnt half your glycogen stores on a casual bike ride, unless you were putting in many sprints in the ride.  Skeletal muscle fibers fall into two basic groups, fast twitch for sprints (which are higher in glycogen and lower in fat stores) and slow twitch (for sustained effort, lower in glycogen and higher in fat stores).  The enzymes for metabolism also vary in amount.  You would have been using mainly slow twitch muscle fibers and their fat stores.

Ideas, a program on CBC Radio 1, has a fascinating discussion of fascism in the US, called Flirting with Fascism: America's New Path? (The link takes you to a short article on the topic and an audio player so you can listen.)

An idea I had not considered before:

Quote
Fascism looks different in different cultures, depending on that culture. In fact, it is the essence of fascism to have no single, fixed form.
- Henry Giroux

Considering that, it is no surprise that it presents like reality TV in the US but wears a different skin elsewhere. There are still common underlying behaviours and practices that are common to all the variants, no matter the mask fascism wears.

Administrator Comment Let loose of your butts now, and continue discussing the episode here, and Cara-carping elsewhere.
