My Mathematical Jewellery Collection

Today I'm going to a barbecue hosted by one of my colleagues. The theme is maths. We will be doing maths puzzles and games, and there is a prize for the most mathematical outfit. On reading this I exclaimed "What shall I wear?!" Not, as you might think, because I don't own any mathematical clothing. In fact it was because I own so much, that choosing was going to be difficult.

Two of my absolute favourite things in the world are maths and fashion. When you combine the two, you get mathematical fashion. And I LOVE it. I have a few mathsy clothing items, but I'm not going to show you those in this post. This post is dedicated to perhaps my favourite aspect of fashion: jewellery.

At my academy I'm known by both staff and students for having a massive collection of bold and bright rings and necklaces. A subset of this collection I will be showing to you today.

First up, my absolutely amazing, custom-made SOHCAHTOA necklace;


I bought this necklace from one of my favourite jewellery shops, Tatty Devine. As well as stocking quirky and unique perspex jewellery, they make name necklaces (like Carrie's from SATC). Seeing this feature gave me the genius idea of turning my favourite maths word into a necklace. I thought long and hard about what word (containing nine letters or fewer) to choose. I settled on SOHCAHTOA because it's so recognisable, not to mention useful. I've had several strangers see it and proudly exclain "I remember that! It means..." which is so nice to hear!

I think my favourite thing about this necklace is my students' reactions when I tell them I had it custom-made. I think to them it just confirms my status as geekiest teacher ever.

Onto my next necklace: The Infinity necklace:

I bought this necklace on Amazon after a lot of searching. I had decided I wanted a necklace in the shape of the infinity symbol, and then set about trying to find one, which is the complete opposite of how I normally shop, where I see something I never knew I wanted and then buy it immediately. This necklace is sterling silver and contains an actual real diamond, which sadly my poor eyesight inhibits me from seeing. Amazon assures me it is there, though.

Necklace number three: the Rubik's Cube:


Everyone loves my Rubik's cube necklace. I have been nearly strangled countless times as students grab it as  I walk away. Nobody can resist turning it a bit, which is why it is a jumbled mess. I am actually rubbish at solving them, although I keep telling myself I will learn the algorithms soon. My friend Emma appeared to learn overnight when she got one for her birthday, but knowing her she probably spent hours and hours learning it obsessively.

Oh, I almost forgot to tell you where this amazing necklace is from! I got it from Folksy, a brilliant website where random people sell all kinds of handmade and vintage stuff. I have bought so many things from there. The necklace was from a seller called Mary Quite Contrary.


And now, a bracelet:

I bought this bracelet quite recently from Folksy, from a seller called I heart my art. It was the only one of its kind, which makes me feel special. Check out her other items though. I like how the bracelet contains "e" because most of my students don't know about the exponential constant, so they'll ask questions about it. Any excuse to talk about e and logs! Although I bet most of them just assume it stands for Emma.

Next, my Origami necklace:

Boy was this hard to photograph! This little stunner really is origami: it was made from a single square of silver and folded into the iconic crane. I saw a very similar necklace on Anthropologie, one of the most beautiful shops in the world, but it cost way too much so I went looking elsewhere. I found this on Etsy, which is basically the American version of Folksy. I bought it from the hugely talented AllegroArts who handmakes all of these stunning origami pieces. This exact necklace can be found here.

.
So that's my mathematical jewellery collection as it stands at the time of writing. I fully expect it to be twice the size this time next year!

I will leave you with one last photo: a little cutie I just had to buy from Ryman's as I was picking up my back-to-school stationery:

I just can't resist cute geekiness.

Playing to Lose

(I was contemplating calling this post "Every Loser Wins", but I hate that song).

As all of you should know by now, I'm a winner. I win things. So when my friend Stacy challenged me to a game of Noughts and Crosses today, I was prepared to win. Until she said this:

"The winner is the person who loses. The aim is to NOT get three in a row".

As you can imagine, I was flummoxed. Winning is easy, losing is difficult. She told me to go first, which, now that I think about it, was a sneaky way of increasing my chance of winning - and hence losing. I obviously avoided the middle square. I figured the corner squares were also too good to use. So I opted for a side square. That decision was pretty easy. The rest was not so trivial. Stacy lost the game, and hence won. Apparently I am such a winner that even when I'm trying to lose, I win.

Please please please grab your partner/your child/your flatmate/the guy next to you on the bus and challenge them to lose a game of Noughts and Crosses. It's the only way you can really think about the strategy involved.

Have fun!

Why We Actually Won The Olympics

Before this year, I'd never watched so much as one minute of an Olympic event. Not even China's opening ceremony last time (I have a phobia of fireworks). I am an incredibly competitive person, and the idea of watching a massive competition into which I'm not even entered, really holds no interest to me. Who cares what happens? The bottom line is, I'm not coming home with a shiny medal around my neck.

But then I went to spend a week in the house of a family who were interested in the Olympics, and (this is important) actually had television (we stopped buying our TV licence several years ago as our favourite shows only air in Japan anyway). I didn't have much else to do that week, no longer being a fifteen minute walk from a city centre (and hence, shops) so I found myself watching the Olympics A LOT. And I found myself enjoying it. I finally got it: sure, I wasn't going to win anything, but my country would, and in a way, me and my country are one and the same. I suddenly understood what Nick Hornby was on about in Fever Pitch (OK, I never actually read it, because, I enjoyed About A Boy and all, but seriously, a book entirely about football?) and I felt that I was Team GB. It was a great feeling.

And then we didn't win.

Those of you who know me well know that I don't particularly enjoy not winning. Please note this only applies to competitions I deem worthy: me always failing to win at Laser Quest, Mario Kart, and anything that involves Geography does not bother me in the slightest. Because they're stupid. But the Olympics was something I wanted to win, something I thought I was really good at (by me, I mean Team GB of course). I wasn't going to let stupid countries like China and the USA beat me. It's not fair: they already have crazy cheap designer clothes and fifty flavours of Pop Tarts, why do they have to have this too?!?

Naturally I did what I always do when I am told I have not won. I set about moving the goalposts, scouring the rule book, and  examining the data to try and find a way that means I actually won. But whichever way you count the medals, we were not higher than third place.

There was only one thing I could do: "To the math cave!!"

I'm sure that anyone who is even slightly mathematically minded automatically saw a problem with the scoring system. I don't mean the fact that it's all done on the number of Golds and not on a 5-3-1 system, because we still wouldn't win then. I'm sure that when most people looked at the scoreboard, their first thought was "Well of course those two countries are winning, they're absolutely massive". China and the USA are well known as having huge populations, along with India, Brazil and Indonesia (interesting point: this is probably the one geographical fact that I actually know without having to look it up. Maths teachers from my Academy will know why). Is it really fair that we are being compared to countries with 5 or even 21 times more people than us? (I had to look that up). If we randomly divided the USA into five pieces, and selected the best athletes from each piece, would they still be the best? And if we cut China into 21 pieces? I don't think so.

So, here comes the maths: I have created a table of the competing countries, and their number of golds per 10 million people. This is like doing population density (urgh, there is way too much geography in this post) but instead it's gold density. Except out of the number of people, not the area of land. Hmm. OK.

 
Country Golds Population (10 millions to 3sf) G/10mill (2 dp)
USA 46 31.5 1.46
China 38 135 0.28
Great Britain 29 6.23 4.65



As you can see, we're actually 3 times better than the USA, and loads better than China. So, we actually should have w... Wait a minute. What?!?! Looking further down the list I can see some pretty disturbing numbers. I'd better give you the whole table. This is it ordered by golds:

So Grenada (a country I'm not even sure I've heard of) has stormed the league table with a whopping 95, making our 4.7 look pretty pathetic. We don't even make the top ten! Random places like Lithuania and Slovenia (who?) have done well, and places that I'm sure only exist for people to take holidays in have managed to come second and third!

I was really hoping that maths would prove we won the Olympics. I suppose this is why I should work out all the data BEFORE writing a blog post. It's not my fault: how was I supposed to know that our little Island actually has a lot of people on it? I felt so sure we were one of the smallest countries. I mean, we only have two types of Skittles over here! Big countries have at least five (including the sour ones, mmmm)! I am outraged.

And before anyone mentions it: the failure of this post has absolutely nothing to do with my lack of geographical knowledge.

The Point of This Post

This post has been a cluster-fudge of poor formatting and lazy researching, so you probably want the payoff now. Well here it is: whatever country you're in, think about doing the following activity at the start of the new term. Announce to the class: "I don't know what you've heard on TV, but Grenada actually won the Olympics". They'll be like, what? Show some pictures of the beautiful country of Grenada, and pictures of, uh...  *googles* nutmeg and mace and the uh... Grenada dove. Then, with or without giving them any extra information or instructions, but giving them access to the internet, get them to find out why Grenada actually won. I'm sure that intelligent pupils will be able to work it out, and you can give them lots of hints if need be. Extension: get them to prove that another country actually won the Olympics (e.g. by looking at the number of golds per GDP or something).

If you're worried the kids will google and find this blog and get the answer from here, fear not. As if any teenager is going to read through this long, dull piece! I'm surprised you've got this far, to be frank.

My Final Conclusion


That last bout of googling I did to find out the main exports and national bird of Grenada revealed something interesting to me: Grenada is a Commonwealth country. Do you know what that means? Yep, it's owned by Queen Elizabeth. Who? Yep, the Queen of England. So technically, technically, we won the Olympics. I knew it!!!
