## Strategic dating: The 37% rule

How to find love using the numbers game. Image: iStock. This self-proclaimed Type A personality figured out the perfect love formula and is now happily married. When I became single in my mid-twenties, I decided to get serious about dating. The rest of my life was great: I had a successful career, friends who made me laugh, and I’d just come back from a three-month backpacking holiday. My Type A personality and obsession for planning stuff helped me achieve life goals.

All of us mathematicians have discovered a sad truth about our passion: It is pretty hard to tell anyone Mating, Dating, and Mathematics: It’s All in the Game.

So how do we learn to discern between a love that is imperfect, as all meaningful real relationships are, and one that is insufficient, the price of which is repeated disappointment and inevitable heartbreak? Making this distinction is one of the greatest and most difficult arts of the human experience — and, it turns out, it can be greatly enhanced with a little bit of science. Mathematics is ultimately the study of patterns — predicting phenomena from the weather to the growth of cities, revealing everything from the laws of the universe to the behavior of subatomic particles… Love — [like] most of life — is full of patterns: from the number of sexual partners we have in our lifetime to how we choose who to message on an internet dating website.

These patterns twist and turn and warp and evolve just as love does, and are all patterns which mathematics is uniquely placed to describe. Mathematics is the language of nature. It is the foundation stone upon which every major scientific and technological achievement of the modern era has been built. It is alive, and it is thriving. In the first chapter, Fry explores the mathematical odds of finding your ideal mate — with far more heartening results than more jaundiced estimations have yielded.

She points to a famous paper by mathematician and longtime singleton Peter Backus, who calculated that there are more intelligent extraterrestrial civilizations than eligible women for him on earth. Backus enlisted a formula known as the Drake equation — named after its creator, Frank Drake — which breaks down the question of how many possible alien civilizations there are into sub-estimates based on components like the average rate of star formation in our galaxy, the number of those stars with orbiting planets, the fraction of those planets capable of supporting life, and so forth.

Fry explains:. Drake exploited a trick well known to scientists of breaking down the estimation by making lots of little educated guesses rather than one big one. The result of this trick is an estimate likely to be surprisingly close to the true answer, because the errors in each calculation tend to balance each other out along the way.

Generally they ignore the history of mathematics in Africa south of the Sahara and give the impression that this history either did not exist or, at least, is not knowable, traceable, or, stronger still, that there was no mathematics at all south of the Sahara. In history, to Europeans, even the Africanity of Egyptian mathematics is often denied or suffers eurocentric views of conceptions of both ‘history’ and of ‘mathematics’ form the basis of such views.

It is a small lake about 30 miles by 60 miles. The place where their remains were found has a name now given to these people – Ishango. Among their remains is the second oldest mathematical object the oldest is here in Africa. Some say that the Ishango Bone is the oldest table of prime numbers. Marshack later concluded, on the basis of his microscopic examination, that it represented a six-month lunar calendar.

The most interesting, of a large number of tools discovered in at Ishango, is a bone tool handle called the Ishango Bone now located on the 19th floor of the Royal Institute for Natural Sciences of Belgium in Brussels, and can only be seen on special demand. At one end of the Ishango Bone is a piece of quartz for writing, and the bone has a series of notches carved in groups shown below. It was first thought these notches were some kind of tally marks as found to record counts all over the world.

However, the Ishango bone appears to be much more than a simple tally. The markings on rows a and b each add to Row b contains the prime numbers between 10 and

Love can be glorious, life-affirming and blissful. The issue isn’t just the parade of less-than-promising partners many daters confront. The problem is also figuring out what constitutes “good enough. In a world of some nine billion or so people, how can you know when the nice guy or gal you’re currently dating is the best you’re going to find? Are you settling down — i. For some lucky percentage of lovers, violins play, the heart beats fast, and the decision is blazingly obvious.

You simply know you’ve found “the one. Wait, what? Math, you’re probably thinking, you must be crazy! But at least one mathematician claims that knowing a little bit about the area of mathematics known as optimal stopping theory can help lovers decide whether to keep swiping right on Tinder or to get out of the game for good. In a timely and entertaining post on the TED Ideas blog mathematician Hannah Fry explains that this type of math was designed to handle just the sort of challenges faced by those looking for love.

Such a list would be pretty pointless by then, but if only you could have it earlier, it would make choosing a life partner a fair sight easier.

## Mathematicians are strange!

First off, why are you assuming that because someone is a mathematician, they have “stuff they like to do in general”? The friends I have in Math couldn’t really be more different. They’re as diverse as any other set of graduate students, in my experience.

Anecdotally many mathematicians report a shared genealogy with Swiss mathematician Leonhard Euler, born in Most of the world’s.

Our prehistoric ancestors would have had a general sensibility about amounts, and would have instinctively known the difference between, say, one and two antelopes. In the absence of settled agriculture and trade, there is little need for a formal system of numbers. Early man kept track of regular occurrences such as the phases of the moon and the seasons. Some of the very earliest evidence of mankind thinking about numbers is from notched bones in Africa dating back to 35, to 20, years ago.

But this is really mere counting and tallying rather than mathematics as such. Pre-dynastic Egyptians and Sumerians represented geometric designs on their artefacts as early as the 5th millennium BCE , as did some megalithic societies in northern Europe in the 3rd millennium BCE or before. But this is more art and decoration than the systematic treatment of figures, patterns, forms and quantities that has come to be considered as mathematics.

Mathematics proper initially developed largely as a response to bureaucratic needs when civilizations settled and developed agriculture — for the measurement of plots of land, the taxation of individuals, etc — and this first occurred in the Sumerian and Babylonian civilizations of Mesopotamia roughly, modern Iraq and in ancient Egypt. According to some authorities, there is evidence of basic arithmetic and geometric notations on the petroglyphs at Knowth and Newgrange burial mounds in Ireland dating from about BCE and BCE respectively.

These utilize a repeated zig-zag glyph for counting, a system that continued to be used in Britain and Ireland into the 1st millennium BCE. Stonehenge , a Neolithic ceremonial and astronomical monument in England, which dates from around BCE, also arguably exhibits examples of the use of 60 and in the circle measurements, a practice which presumably developed quite independently of the sexagesimal counting system of the ancient Sumerian and Babylonians.
