One more for this little project and then we will take a vote.  So many difficult and sad things related to Covid and lockdowns in various parts of the world these days. Maybe puzzles and games seem frivolous and just make it worse. Or maybe music, art, chess, Go, Bond, James Bond are a good thing for some...  
If I receive even one vote to keep going here, I will be happy to continue this calendar. Otherwise, I wish you all peace, warmth, and better times ahead.

Keep going!

I think I got most of the Bond ones. But I refuse to google and I also refuse to answer any question about a Bond film that has nothing to do with an Ian Fleming book except a title!

References: 
International Skiing History Association - US Resorts
Canadian Skiing History - Banff

3. Roughly how many countries in the world offer some form of ski area/resort?

 
About 80 countries around the world have ski areas or resorts. List of Ski Resorts International - Wikipedia

4. Besides ski gear and suitable clothing, name an essential item to bring with you on a heliskiing adventure.

 
Avalanche safety gear!

5. Name three of the most challenging ski runs in the world. 

 
Your choice here: The World's Most Challenging Ski Runs - SkiOlympic.com

6. Where does the word “ski” come from?

 
The word “ski” originates from the Old Norse word “skio,” meaning a split piece of wood.

7. Where was the oldest known ski in the world found and how old is it estimated to be?

 
The oldest know ski was discovered in Sweden and dates back to 4,500-2,500 BC. (Of course, our resident Norsemen may disagree vehemently with this one.)

8. How many calories does downhill skiing burn per hour? (given moderate effort)

 
Harvard Medical School created a table for calories burned during various sports activities.
For downhill skiing, a 125 pound person burns 360 calories/hour; a 155 pound person burns 446 calories/ hour; and a 185 pound person burns 532 calories/hour.

From the same report: 396, 492, and 586, respectively. 

10. Cross-country skiing is said to be good training for what off-world activity?

 
Astronauts heading to the Moon should learn the art of cross-country skiing. Harrison Schmitt, part of the 1972 Apollo 17 crew, said it would allow them to explore faster and more easily.

By the way, I am looking for a good way to build better, more interconnected puzzles.

Going back to my childhood, my grandmother enjoyed working on The New York Times Sunday puzzles, which were quite challenging, but nicely laid out:
NYTpuzzle.JPG
If any of you have clever ideas of how to do this without hours of structuring effort on my part, I'd be happy to hear them.

Also, on Taleb; recommended reading for sure, especially his many appendices, notes, and bibliographies at the end of the books. 

Fine to read and reread the single books alone, but Nassim provides plenty of hints and signposts for a longer and more circuitous adventure. I've certainly gone on such journeys over the years and cold winter nights apres ski are perfect for them!

Next up - mathematical trivia on the weekend. Requests for calendar content are welcome. Just keep your suggestions in the G, PG, or R-rated range; thank you! ; )

Back to Square One

A Quiz on Ancient Times and a Quartet: The Answers

1. Name the famous Babylonian tablet that features derivations of a certain form of triples.

Plimpton 322 - The tablet appears to be working what are now known as Pythagorean triples, but it was created more than 1,000 years before Pythagoras was born.

2. A rare and fragile relic of early Egyptian mathematics, written on reeds.

The Rhind (Mathematical) Papyrus, circa 1650 BC.

3. An ancient Greek mechanism used to predict astronomical positions and eclipses; it was discovered in a shipwreck in 1901.

The Antikythera mechanism. 

4. Arab mathematicians and astronomers spent a great deal of time developing and refining this “star taker” device.

The astrolabe.

5. The Greek mathematician Hippasus came up with this mathematical construct, so disturbing at the time that it was banned and he was exiled or possibly drowned for his discovery. 

Irrational numbers.

6. Euclid’s 13-book set, which remains the basis for much of mathematics today.

The Elements, circa 300 BC.

7. Among many accomplishments, Persian polymath Muḥammad ibn Mūsā al-Khwārizmī made significant contributions to which branch of mathematics?

Algebra, with his publication of The Compendious Book on Calculation by Completion or al-Kitāb al-Mukhtaṣar fī Ḥisāb al-Jabr wal-Muqābalah, from which the math gets its name: al-Jabr.

8. A Platonic Solid is defined as is a convex regular polyhedron in three-dimensional Euclidean space. How many Platonic Solids are there, what are their names, and how many faces do they have?

There are five Platonic Solids: Tetrahedron (4); Cube (6); Octahedron (8); Dodecahedron (12); Icosahedron (20).

9. Around 150 CE, Ptolemy wrote the Almagest, an influential treatise on the apparent motions of the stars and planetary paths. What was its major misconception?

Ptolemy’s Almagest presented (and canonized) a geocentric model of the universe. This misperception persisted for about 1,200 years.

10. Jumping ahead in Geometry: This quaint satire, published in 1884, featured A. Square and his journey to The Land of Three Dimensions. What was the name of this book? Bonus: Who was its author?

Flatland, by Edwin A. Abbott
