3.1415

This is really only Pi Day, and a very special one this year, to those somewhat backwards countries who post the date in neither descending nor ascending order of significance.

piToday is Pi Day, pi being the ratio of the circumference of a circle to its diameter. But you knew that. You probably were even aware that pi was a very old number, and, of course, an infinite decimal, roughly equivalent to 355/113.

But did you know: “Pi (rather than some other Greek letter like Alpha or Omega) was chosen as the letter to represent the number 3.141592… because the letter π in Greek, pronounced like our letter ‘p’, stands for ‘perimeter’.”

Of course, this is really only Pi Day, and a very special one this year, to those somewhat backward countries who post the date in neither descending nor ascending order of significance, but rather Month, Day, Year.

The primary country using this system is the United States, so it gets noticed. The others, as far as I can tell, are Belize and the Federated States of Micronesia, though Canada, Kenya, and the Philippines use multiple designations, including MMDDYYYY.

Since pi and pie are homophones, some people seem to think that today is Pie Day. But Pie Day in 2015 was January 23.

Still, all sophisticated folks, understandably, recognize the pie as the perfect food, available as dinner (pot pie, e.g.) or dessert, and will use any excuse to eat, or get hit in the face with, pie.

Here’s Dustbury’s pi post from last year, which shows that I’m very pi; either I go on forever, or I’m irrational. Take your pick.

Born this date: Albert Einstein in 1879, who undoubtedly used pi in some calculations; and Quincy Jones in 1933, who recorded and produced many albums that were shaped like a circle.

Both my sister’s boyfriend Mike and my friend, artist Stephen Bissette, turn the big SIX-OH today. Happy natal day to them.

Cheaper pizza

The Daughter is doing order of operations at school.

General problem 2I went to the local pizzeria on a recent Saturday night. The cost was $10.50; I gave the cashier a $20 bill and a $1 bill. But he gave me back the dollar bill, and then gave me change for the $20, which was $9.50.

As it turned out, they were out of five-dollar bills, so he was going to give me nine one-dollar bills and 50 cents. Seeing this, the owner yelled, “Just charge him [me] ten bucks.” The clerk says, “But I’ve already closed the register.” The owner overrides the register to reopen it, puts back the $9.50 and gives me a $10 bill.

Of course, I gave the clerk $21 in the first place so he would not have to give me a bunch of ones. If you’ve ever been in retail, you know that you don’t want to give away ones if you can help it, and certainly not nine of them. I knew that, the owner knew that, the clerk, not so much.
***
For some reason, I’m reminded by a story from long ago, where a guy I knew wanted to buy milk and a newspaper. At the time the milk was 99 cents and the newspaper, 35 cents. But the register wasn’t working properly, and couldn’t give the total, though it could give change. The problem is that the clerk couldn’t figure out the change from $2, because he didn’t know the total of the purchase.

The guy tried to explain: “99 cents is a penny less than a dollar, so it’s $1.34. These are non-taxable, so it’s $2 minus $1.34 is 66 cents.” This was too complicated.

I worry that when the computers all go down, no one will know how to add and subtract, never mind do multiplication and division.

gas_prices I was watching the NBC Nightly News and saw this story: Gas Prices Drop to Lowest Level in Nearly Four Years, using the picture. I had to write to them.

“The average price drop is NOT 30% [as Brian Williams said], it’s 30 CENTS, as the graphic showed, from $3.34 to $3.04,” I noted. If it had been 30%, the drop would be about $1.

The Daughter is doing the order of operations at school. At a website quaintly called Math is Fun, it reminded me that the order in which one does math problems is:
P
Parentheses first
E
Exponents (i.e. Powers and Square Roots, etc.)
MD
Multiplication and Division (left-to-right)
AS
Addition and Subtraction (left-to-right)

I’ll admit to forgetting where the exponents fit, exactly.

So what is the answer to the item posted above?

Soccer, a.k.a. football; and lies on the Internet

I’ve seen any number of people who refused to believe that an event happened because they read it on Facebook, and “Facebook can’t be trusted.”

The first time I ever even had a passing interest in soccer was watching some eight-year-olds play in the early 1980s. Now my daughter has participated the last three years, so I’ve become vaguely informed about the nuances. The Daughter wants one of those new soccer balls, called a brazuca, but I hear it costs $160; not happening.

Not that I would dis anyone who didn’t like the sport because they thought it was boring; I used to think so myself. But I figuratively rolled my eyes at certain Americans with their observations. Ann Coulter and her “Any growing interest in soccer a sign of moral decay” is self-evidently idiotic, but I note the source.

I was more annoyed, actually, with sportscaster Keith Olbermann, who suggested that the US shouldn’t have advanced to the knockout round because Portugal was the better team, based on “momentum.” If we were seeding the March Madness men’s basketball playoffs, one can factor in “momentum.” But it seemed to me to be the height of arrogance to suggest such a change at FIFA, who’s been doing this World Cup thing, in a sport most Americans still do not understand, since 1930. Keith should butt out.

Now satirical analysis, such as the piece Ken Levine provided, is welcome.

A female friend of mine noted, not just that the players collectively are quite buff, but that even her most macho-sounding male friends were making the same observations. And I noticed that the refs in these games have to move nearly as much as the players.

I saw bits and pieces of the earlier matches. But I managed to see the last 77 minutes of the epic 120-minute match between the US and Belgium, which the Americans lost 2-1, despite epic goal play by Tim Howard, the most saves in at least 50 years. After the US scored its goal at 107 minutes, I was on my feet the rest of the match, a clear sign I was really into that game.

Moreover, I started figuring out the notations online for the yellow card (penalty), substitution, and how much extra time would be allowed per period. I enjoyed it more because I understood it more than I ever have before. Still think the stoppage time is weird to me and seemingly arbitrary, but maybe it’ll make sense, eventually.

Amy Biancolli writes about the thrill of a good loss. And mostly unrelated, here’s a comic about the Existential World Cup.

Early on, I picked Argentina to win the World Cup. I figured it was a strong team that didn’t have so far to travel, and that the host Brazilians would wilt under the pressure. If the US HAD won its Belgium game, it would have been up against Argentina, and I would have had a quandary. OK, I wouldn’t really; it’d just be a classic head/heart bifurcation.

Oh, here’s something I don’t get: about a week into the World Cup, I saw an article that indicated that the Argentina team had been banned from play because of some infraction. When I click on the article, it was one of those GOTCHA phony stories, and I was 123,456th person (or whatever) to fall for it. As someone who values real information, the site made me irritable. (But not the temporary change in the Wikipedia entry for U.S. Secretary of Defense to ‘Tim Howard’, which was an obvious prank.)

It was the second time in less than a month I saw the more annoying version of this; some guy from Walking Dead, a show I never had watched, supposedly died. But it was another “GOTCHA to click through to this lie, dummy” thing.

I understand that one has to verify things, say, that one sees on Facebook. Designing Women actor Meshach Taylor died late on June 28 – at age 67, sad (yes, I watched the show) – and his family had announced that he had begun his “grand transition” on June 27. So some people began posting news of his death soon afterward. I waited until I had seen sources I trusted (both the LA Times and the Hollywood Reporter, which is generally good with deaths of celebrities) before I would post it.

But I’ve seen any number of people who refused to believe that an event happened because they read it on Facebook, and “Facebook can’t be trusted.” I’m not talking about anything mildly controversial, such as climate change; I’m talking PAST weather reports from NOAA.

OK, one more pet peeve often posted on Facebook: it’s this calendar showing, e.g., August 2014, which has five Fridays, five Saturdays, and five Sundays. And the graphic says, “This won’t happen again for another 823 years.” But the calendar for 2014 is EXACTLY the same as the calendar for 2003, 1997, 1986, and will be repeated in 2025, 2031, and 2042. Moreover, any month with 31 days in which the 1st falls on Friday, is in this category. Examples from recent past and near future: January 1988*, 2010, 2016* and 2021; March 1996*, 2013, 2019 and 2024*; May 1992*, 2009, 2015 and 2020*; July 1988*, 2011, 2016* and 2022; August 2008* and 2036*; October 2004*, 2010, 2021 and 2032*; December 2000*, 2006, 2017 and 2028*. *leap years.

This meme is so OBVIOUSLY wrong (to me), that the fact that SO many people have sent it shows a certain math phobia or unawareness. Ah, an interesting observation that I can add to a book review I’m doing…

April Rambling: Buy the niece’s new album, and end Daylight Saving Time

“Your attention to detail often makes you isolated and aloof, but your heart is also deeply passionate and romantic.”

rjcoldfact
New album from Rebecca Jade & The Cold Fact the debut release from San Diego-based eclectic soul/funk band. RJ is my niece, my sister Leslie’s daughter.
From NBC San Diego: “Not everything on April Fool’s Day was a joke. Rebecca Jade & the Cold Fact released their self-titled debut and it’s no laughing matter. Channeling everyone from Candi Staton and Betty Davis to Morcheeba and Brightback Morning Light, these 12 tracks of soul and funk are stunners. Do yourself a favor and pick up a copy.”
Another review.
In this picture, she’s the one in the blue dress.

After watching this video, I’m even more convinced than I was before: Daylight Saving Time is a waste of time. Having tried to schedule a phone call from the UK at a point when the US is in DST and the UK has NOT yet moved to British Summer Time, I know of which the speaker is talking about.

In one of those Facebook memes: “I’m Picard: Few are smarter and more reliable, but that doesn’t mean you’re bad in a fight. You surround yourself with great people, but maintain a strong devotion to the chain of command. You’re fiercely loyal to your friends and family, but never had time to start one yourself. In the minus column…you can be a touch boring.” And speaking of which: Picard’s tea. Also, Trek-lit reading order.

I’m also Led Zeppelin: “You’re an overachiever and a perfectionist. You work hard at what you do, and it shows. Your attention to detail often makes you isolated and aloof, but your heart is also deeply passionate and romantic. If you continue to refine your skills, you’ll eventually become one of the greatest ever in your chosen field.” Third sentence is almost certainly correct.

Z is for Zero

Helping to working on my daughter’s homework, I get to rediscover centimeters to meters (100), milliliters to liters (1,000), and grams to kilograms (1,000).

Zero has fascinated me for-practically-ever. I saw this article in BoingBoing, which led to this piece in the Guardian:

“Only [India] introduced a symbol, 0, and treated it as if it was a normal digit just like all the others from 1 to 9. The invention of the number zero was possibly the greatest conceptual leap in the history of mathematics.

“But why did the Indians make this leap and not China or Babylon? …

“India made another contribution to world culture as well as zero: the idea of nirvana, the transcendent state of “nothingness”, when you are liberated from suffering and desires.

“In fact, the word used in philosophical texts to mean nothing or the void, is “shunya”, the same word later used to mean zero.

“For George Gheverghese Joseph, a maths historian at the University of Manchester, the invention of zero happened when an unknown Indian mathematician about two thousand years realized that “this philosophical and cultural concept would also be useful in a mathematical sense.” …

“In the modern world, it is common to see religion and science as always in conflict. Yet in ancient India, one cannot untangle mathematics and mysticism.”

I read Thinking in Numbers, On Life, Love, Meaning, and Math by Daniel Tammet this autumn. He wrote about Shakespeare’s Zero, how the Bard wrote a lot about nothingness and was “one of the first generations of English schoolboys to learn about the figure zero.”

For zero means nothing, but, combined with other numbers, can represent an incredible size, e.g., a one, followed by a zero (10), or two zeroes (100), or many more. Helping to work on my daughter’s homework, I get to rediscover the relationship of centimeters to meters (100), milliliters to liters (1,000), and grams to kilograms (1,000).

Of course, we often make a big deal about a birthday or anniversary when it contains a zero in the one’s place, and more so when it’s in both the ones and tens place. Read the Wikipedia piece about zero.
