What’s the best way to see all of Catriona’s puzzles? I see that you have posted collections 4 (?) times. Is that the complete set so far? Do I need to wade into twitter to find one-off puzzles?

Sorry for jumping into the middle of a conversation… but Your main argument is, these puzzles (and geometry in general) don’t have any real-life application. Well, I think as long as they challenge someone’s mind they are much more useful than many other things such as pointless games and surfing social media etc. Why do we care about real life applications only when it comes to math and puzzles and not other pointless activities that might occupy most of our spare time?

Yes – those are the five posts I’ve done featuring her puzzles. She actually has *lots* more on her Twitter! http://twitter.com/cshearer41

Unfortunately, it reminds me of my horrendous time in high school when I had that stuff rammed down my throat. The worst of it was that no one would ever take the time to explain how and why it would be helpful in real life. Thus, in my future careers in accounting and law, I say again that it is just as useless to me today as it was 40 years ago.

Oh, for sure! I think way too many people, through no fault of their own, have a terrible experience with school math, and that understandably shapes their outlook on the subject for decades thereafter.

Some of Catriona’s puzzles yield to a single geometric insight. This one offers a different kind of pleasure. Catriona explains: “I doubt many people could do this one in their head – I couldn’t – but it makes the highlight reel on account of an unreasonably nice answer.” (See the original here.)

1. Norwegian: habitational name from a farm so named, most probably from bu ‘small house, hut’ (compare Buan). 2. Italian: nickname for a powerfully built man, from bue ‘bull’, a dialect form of bòve (from Latin bos, genitive bovis). In some cases it may have been originally a metonymic occupational name for a herdsman. Compare Lo Bue. Some characteristic forenames: Scandinavian Ragnhild, Sig, Svein.

In terms of ethnicity, the data from the Decennial U.S. Census shows a shift within the ethnic identities associated with the surname Bue. Over the decade from 2000 to 2010, the number of people identifying as Asian/Pacific Islander more than doubled, increasing from 3.33% to 7.08%. There was also a significant increase in those identifying as Black, from 0.72% to 2.19%. The percentage of Bues identifying as White decreased slightly from 88.70% to 83.91%, and the Hispanic population saw a moderate increase from 4.06% to 4.63%. It is important to note that the data for those identifying as Two or More Races and American Indian and Alaskan Native were suppressed in 2010 for privacy reasons.

Sad but true. Unfortunately for me, my outhouse of a high school had a mentality of LEARN THIS OR ELSE. Consequently, I have both a lifetime hatred of my old high school and and a triggered aversion to all things STEM, I’m afraid. And yet, college and law school was so much fun

These puzzles, for what it’s worth, are just that: puzzles. They belong to the same family as crosswords, or sudoku, or jigsaw puzzles. Everyone will have different preferences on these – e.g., I enjoy crosswords and these geometry puzzles, am neutral-positive on sudoku, and don’t like jigsaws – but it comes down to how much you enjoy the activity itself, rather than any promise of usefulness.

Micro drill bits have smaller diameters than other styles of drill bits and are used for creating precise, tiny holes with close tolerances.

There are some arguments to be made that a good course in geometric proof is great preparation for law (Lincoln and Jefferson, for example, were both huge fans of Euclid, and Lincoln made this case explicitly, saying that geometric proofs are what taught him how to construct an argument). But a bad course in geometric proof is not very good preparation for anything!

They are arranged in roughly ascending order of challenge, but can be consumed in any order (unlike most four-course meals).

Catriona describes this as a riff on her very first puzzle (which I dubbed Garden of Clocks). I’ll take this moment to make the vapid point that, in addition to impeccable geometric taste, Catriona always chooses the perfect colors. (See the original here.)

I don’t have anything against the puzzles. My only point is that one would be a little disinclined to see the utility of an academic topic when one is made to learn it with a gun at his back…again without ever being told of it’s real life relevance.

This website was useful because there were a lot of different examples, so when I have to narrow down my topic this will be a great website to refer back to.

The surname Bue based on the Decennial U.S. Census data has seen a rise in its popularity between 2000 and 2010. In the year 2000, it was ranked 31,658 in terms of prevalence in the United States, however, by 2010, it had climbed to a rank of 30,165, demonstrating a positive change of 4.72%. The actual count of individuals with this surname also increased from 690 in 2000 to 777 in 2010, marking an uplift of 12.61%. Despite this growth, the proportion per 100,000 people remained steady at 0.26.

I am pleased as punch (which is, as I understand it, a very pleased drink?) to offer you four new puzzles from geometric visionary Catriona Shearer.

Where is this going to ever be relevant in one’s life if one doesn’t work in a stem field? That stuff is a worthless to me now as it was when I had it shoved down my throat 40 years ago in high school.

People kept asking Catriona if this one was a “trick question.” It’s not; just a tasty little hors d’oeuvre, which you may wish to nibble at for a while, or to eat in a single bite. (See the original here.)

By the way, it’s a scientifically proven fact that puzzles and mind games help preventing or postponing brain deterioration and diseases such as dementia, Alzheimer’s and such.

In any case, geometry is like most subjects – whatever the benefits of learning it, most people will be pretty much fine without it.

I love this construction. Nothing but midpoints, connected with the elegance and economy of a calligrapher. “I’m sure this is a classic that’s been done many times,” says Catriona, “but it was new to me.”
