How November 2018 Treated My Mathematics Blog


I knew that November 2018 was going to be a less busy month around here than October would. I didn’t have the benefit of hosting the Playful Mathematics Education Blog Carnival for it. I’m hoping to host the carnival again, though. Not until after the new year. Not until after I’ve finished the Fall 2018 A To Z and have had some time to recuperate. It’s a weird thing but writing two 1500-to-2000-word essays each week hasn’t lightened my workload the way I figured. If you’re interested in the current Blog Carnival, by the way, here it is. Anyway, as reversions to the norm go, November was not bad. Here’s what it looked like.

November 2018. Views: 1,611. Visitors: 846. Views per visitor 1.90. Total posts: 23.
WordPress readership figures around here for July 2016 through November 2018. I was able to capture this picture just before anyone visited me in December, which I’m going to say is because I had really good reflexes and not because nobody wanted to deal with me the first Saturday of the month.

So there were 1,611 pages viewed here in November. Down from the 2,010 of October, but noticeably higher than September’s 1,505. That’s still a third-highest month (March 2018 was busier still). But it’s weirdly gratifying. There were 847 unique visitors logged in November. That’s down from October’s 1,063, and even September’s 874. I make this out as my fifth-most-visitors month on record. All those months have been this year.

85 things got liked in November. That’s down from October’s 94, up from September’s 65, and overall part of a weird pattern. My likes are definitely declining over time. But there’s little local peaks. If there’s any pattern it’s kind of a sawtooth, with the height of the teeth dropping. I have no explanation for this phenomenon. There were 36 comments in November, well down from October’s 60, but equal to September’s. It’s above the running average of the last two months (28.5 comments per month) but it’s still well below, like, the average commentary you can expect on the Comics Curmudgeon. Granted, we serve different purposes.

Of the most popular essays this month the top two were perennials. Some A to Z stuff filled out the rest. I’m including the top six posts here there was a tie for fourth place, and sixth place was barely behind that. If this reason seems ad hoc, you understand it correctly. Read a lot around here were:

Mutt, hauling a Victrola in: 'Have I ever shown you these valuable records I have?' Jeff: 'No!' Mutt: 'These records are very valuable! They are the first records ever made!' Jeff: 'They sound scratchy!' Mutt: 'Yes, they have some scratches, but they are worth five dollars each!' [ Later that Day ... Jeff is sandpapering a record. ] Jeff: 'I'll surprise Mutt.' (To Mutt). Jeff: 'Now they don't have scratches any more! I sanded them until they were smooth!'
Bud Fisher’s Mutt and Jeff rerun for the 1st of December, 2018. Clearly an attempt to get itself added to my page about how many grooves are on a record’s side. I have no information about when this strip first ran. My gut says the art dates to the 1940s. The word balloons are all recent, computer-assisted reletterings. (Look at the lower end of each letter ‘S’.) The relettering is certainly easier to read than the original cramped and shakily reproduced lettering. (Look at the record player’s ‘Come, Josephine’ text, or the sound effect of Jeff scratching the record clean in the fourth panel to see how bad it could be.) But the relettering is probably why the dialogue has that slightly over-edited, not-quite-human flow we’re used to from Funky Winkerbean.

And where were all these readers coming from? Here’s the roster of countries and their readership totals:

70 countries sent me readers in November 2018. That’s down from October’s 74 but up from September’s 58. 13 of them were single-reader countries, down from October’s 23 and September’s 14. Czech Republic has been a single-reader country for three months. Colombia for four months now.

According to the Insights panel, I start the month at 71,506 total page views for the 1,185 posts I’ve done altogether. It also records 35,384 unique visitors, but I again have to defensively insist WordPress didn’t count unique visitors for the first couple months I was around here. I swear.

I published 23 posts in October. A to Z months tend to be busy ones. These posts held something like 26,644 words in total. For the 165 things I had posted this year, through to the start of December, I averaged 1,108 words per post. That’s up from the start of November’s 996 words per post, but still. I’m averaging 5.3 likes per post, and 2.7 comments per post. At the start of last month I was averaging 5.5 likes and 2.8 comments per post. This is probably not any important kind of variation. There’ve been 450 total comments and 870 total likes this year, as of the start of December.

Are you interested in reading me more regularly? You can put my posts in your RSS reader and enjoy them at your convenience. You can also add me to your WordPress Reader, using the button at the upper-right corner of the page. Also possibly a pop-up menu from the lower-right corner. On Twitter I’m @Nebusj. Through the end of the year I’ll keep working on the Fall 2018 A To Z. And every Sunday plus, usually, some other day of the week I’ll be Reading the Comics for the mathematics stuff. Thanks for considering any of this.

How November 2017 Treated My Mathematics Blog


I was barely done sulking about the drop in readership on my humor blog when I started preparing the mathematics-blog readership report. And readership did drop from October (and September). Not by much, though. There were 1,052 pages viewed here in November 2017, barely less than October’s 1,069. It’s a fair bit under September’s 1,232, but that’s to be expected when I don’t have a strong gimmick going on like an A To Z project.

The number of unique visitors dropped, down to 604 from October’s 614, again a trivial difference. September had seen 672 visitors and that’s a more noticeable drop. Still not much, considering. The number of likes rose a bit, up to 70 from October’s 64. Still down from September’s 98. And all that still way down from, like, a year ago. I don’t know if it’s my shuffling off into irrelevance or if there’s something making likes less of a thing lately. I’d be curious other bloggers’ experience.

I’d started December with 55,419 page views from an estimated 25,617 known unique visitors, although some of them I only know apart because of their nametags.

So what countries have sent me readers? 56 of them, up from October’s 51 but down from September’s 65. How many sent me multiple readers? All but 22 of those. That’s up from October — 13 single-reader countries — and September — 20 single-reader countries — but these things happen. Here’s the full roster:

Country Readers

Japan’s the only country to have sent me a single reader last month too, and no countries have sent me single readers more than two months in a row currently.

So that’s general popularity. What articles were popular around here? One traditional piece. Reading the Comics pieces. And the lovably misguided attempt by Józef Maria Hoëne-Wronski to give us a culturally neutral definition of π broke out to … well, second and third place, anyway:

Also, clearly, I need to think of more simple mathematically-answerable questions that everybody wonders since that record-side question is always popular. And when that is less popular, the question about how many kinds of trapezoid there are turns up.

Anyway, should you have read this and decided you want to be among my hundreds of WordPress followers who somehow don’t show up on the readership statistics, please, do so. There should be a ‘Follow on WordPress’ button in the upper right corner of the page. There’s also a ‘Follow by e-mail’ if you want things sent to an already-overfull box of things you haven’t time to read. Thank you.

How November 2016 Treated My Mathematics Blog


I didn’t forget about reviewing my last month’s readership statistics. I just ran short on time to gather and publish results is all. But now there’s an hour or so free to review that WordPress says my readership was like in November and I can see what was going on.

Well.

So, that was a bit disappointing. The start of an A To Z Glossary usually sees a pretty good bump in my readership. The steady publishing of a diverse set of articles usually helps. My busiest months have always been ones with an A To Z series going on. This November, though, there were 923 page views around here, from 575 distinct visitors. That’s up from October, with 907 page views and 536 distinct visitors. But it’s the same as September’s 922 page views from 575 distinct visitors. I blame the US presidential election. I don’t think it’s just that everyone I can still speak to was depressed by it. My weekly readership the two weeks after the election were about three-quarters that of the week before or the last two weeks of November. I’d be curious what other people saw. My humor blog didn’t see as severe a crash the week of the 14th, though.

Well, the people who were around liked what they saw. There were 157 pages liked in November, up from 115 in September and October. That’s lower than what June and July, with Theorem Thursdays posts, had, and below what the A To Z in March and April drew. But it’s up still. Comments were similarly up, to 35 in November from October’s 24 and September’s 20. That’s up to around what Theorem Thursdays attracted.

December starts with my mathematics blog having had 43,145 page views from a reported 18,022 distinct viewers. And it had 636 WordPress.com followers. You can be among them by clicking the “Follow” button on the upper right corner. It’s up from the 626 WordPress.com followers I had at the start of November. That’s not too bad, considering.

I had a couple of perennial favorites among the most popular articles in November:

This is the first time I can remember that a Reading The Comics post didn’t make the top five.

Sundays are the most popular days for reading posts here. 18 percent of page views come that day. I suppose that’s because I have settled on Sunday as a day to reliably post Reading the Comics essays. The most popular hour is 6 pm, which drew 11 percent of page views. In October Sundays were the most popular day, with 18 percent of page views. 6 pm as the most popular hour, but then it drew 14 percent of page views. Same as September. I don’t know why 6 pm is so special.

As ever there wasn’t any search term poetry. But there were some good searches, including:

  • how many different ways can you draw a trapizium
  • comics back ground of the big bang nucleosynthesis
  • why cramer’s rule sucks (well, it kinda does)
  • oliver twist comic strip digarm
  • work standard approach sample comics
  • what is big bang nucleusynthesis comics strip

I don’t understand the Oliver Twist or the nucleosynthesis stuff.

And now the roster of countries and their readership, which for some reason is always popular:

Country Page Views
United States 534
United Kingdom 78
India 36
Canada 33
Philippines 22
Germany 21
Austria 18
Puerto Rico 17
Slovenia 14
Singapore 13
France 12
Sweden 8
Spain 8
New Zealand 7
Australia 6
Israel 6
Pakistan 5
Hong Kong SAR China 4
Portugal 4
Belgium 3
Colombia 3
Netherlands 3
Norway 3
Serbia 3
Thailand 3
Brazil 2
Croatia 2
Finland 2
Malaysia 2
Poland 2
Switzerland 2
Argentina 1
Bulgaria 1
Cameroon 1
Cyprus 1
Czech Republic 1 (***)
Denmark 1
Japan 1 (*)
Lithuania 1
Macedonia 1
Mexico 1 (*)
Russia 1
Saudi Arabia 1 (*)
South Africa 1 (*)
United Arab Emirates 1 (*)
Vietnam 1

That’s 46 countries, the same as last month. 15 of them were single-reader countries; there were 20 single-reader countries in October. Japan, Mexico, Saudi Arabia, South Africa, and the United Arab Emirates have been single-reader countries for two months running. Czech has been one for four months.

Always happy to see Singapore reading me (I taught there for several years). The “European Union” listing seems to have vanished, here and on my humor blog. I’m sure that doesn’t signal anything ominous at all.

When Is Thanksgiving Most Likely To Happen?


So my question from last Thursday nagged at my mind. And I learned that Octave (a Matlab clone that’s rather cheaper) has a function that calculates the day of the week for any given day. And I spent longer than I would have expected fiddling with the formatting to get what I wanted to know.

It turns out there are some days in November more likely to be the fourth Thursday than others are. (This is the current standard for Thanksgiving Day in the United States.) And as I’d suspected without being able to prove, this doesn’t quite match the breakdown of which months are more likely to have Friday the 13ths. That is, it’s more likely that an arbitrarily selected month will start on Sunday than any other day of the week. It’s least likely that an arbitrarily selected month will start on a Saturday or Monday. The difference is extremely tiny; there are only four more Sunday-starting months than there are Monday-starting months over the course of 400 years.

But an arbitrary month is different from an arbitrary November. It turns out Novembers are most likely to start on a Sunday, Tuesday, or Thursday. And that makes the 26th, 24th, and 22nd the most likely days to be Thanksgiving. The 23rd and 25th are the least likely days to be Thanksgiving. Here’s the full roster, if I haven’t made any serious mistakes with it:

November Will Be Thanksgiving
22 58
23 56
24 58
25 56
26 58
27 57
28 57
times in 400 years

I don’t pretend there’s any significance to this. But it is another of those interesting quirks of probability. What you would say the probability is of a month starting on the 1st — equivalently, of having a Friday the 13th, or a Fourth Thursday of the Month that’s the 26th — depends on how much you know about the month. If you know only that it’s a month on the Gregorian calendar it’s one thing (specifically, it’s 688/4800, or about 0.14333). If you know only that it’s a November than it’s another (58/400, or 0.145). If you know only that it’s a month in 2016 then it’s another yet (1/12, or about 0.08333). If you know that it’s November 2016 then the probability is 0. Information does strange things to probability questions.

A Thanksgiving Thought Fresh From The Shower


It’s well-known, at least in calendar-appreciation circles, that the 13th of a month is more likely to be Friday than any other day of the week. That’s on the Gregorian calendar, which has some funny rules about whether a century year — 1900, 2000, 2100 — will be a leap year. Three of them aren’t in every four centuries. The result is the pattern of dates on the calendar is locked into this 400-year cycle, instead of the 28-year cycle you might imagine. And this makes some days of the week more likely for some dates than they otherwise might be.

This got me wondering. Does the 13th being slightly more likely imply that the United States Thanksgiving is more likely to be on the 26th of the month? The current rule is that Thanksgiving is the fourth Thursday of November. We’ll pretend that’s an unalterable fact of nature for the sake of having a problem we can solve. So if the 13th is more likely to be a Friday than any other day of the week, isn’t the 26th more likely to be a Thursday than any other day of the week?

And that’s so, but I’m not quite certain yet. What’s got me pondering this in the shower is that the 13th is more likely a Friday for an arbitrary month. That is, if I think of a month and don’t tell you anything about what it is, all we can say is it chance of the 13th being a Friday is such-and-such. But if I pick a particular month — say, November 2017 — things are different. The chance the 13th of November, 2017 is a Friday is zero. So the chance the 26th of December, 2017 is a Thursday is zero. Our calendar system sets rules. We’ll pretend that’s an unalterable fact of nature for the sake of having a problem we can solve, too.

So: does knowing that I am thinking of November, rather than a completely unknown month, change the probabilities? And I don’t know. My gut says “it’s plausible the dates of Novembers are different from the dates of arbitrary months”. I don’t know a way to argue this purely logically, though. It might have to be tested by going through 400 years of calendars and counting when the fourth Thursdays are. (The problem isn’t so tedious as that. There’s formulas computers are good at which can do this pretty well.)

But I would like to know if it can be argued there’s a difference, or that there isn’t.
