# Mathematics, Jewishness, and Direction

When I was nearly 18 I was part of the British team to the International Mathematical Olympiad (IMO) in Bucharest (see my account of the experience).  The US team were Jewish1, all eight of them.  While this was noteworthy, it was not surprising. There does seem to be a remarkable number of high achieving Jewish mathematicians, including nearly a quarter of Fields Medal recipients (the Maths equivalent of the Nobel Prize) and half of the mathematics members of the US National Academy of Sciences2.

Is this culture or genes, nature or nurture?

As with most things, I’d guess the answer is a mix.  But, if of culture, what? There is a tradition of Biblical numerology, but hardly widespread enough to make the substantial effects. Is it to do with the discipline of learning Hebrew, maybe just discipline, or perhaps is it that mathematics is one of the fields where there has been less prejudice in academic appointments3.

I have just read a paper, “Disembodying Cognition” by Anjan Chatterjee, that may shed a little light on this.  The paper is an excellent overview of current neuroscience research  on embodiment and also its limits (hence ‘disembodying’).  One positive embodiment result related to representations of actions, such as someone kicking a ball, which are often depicted with the agent on the left and the acted upon object on the right.  However, when these experiments are repeated for Arab participants, the direction effects are reversed (p.102).  Chaterjee surmises that this is due to the right-to-left reading direction in Arabic.

In mathematics an equation is strictly symmetrical, simply stating that two thinsg are equal.  However, we typically see equations such as:

y = 3x + 7

where the declarative reading may well be:

y is the same as “3x + 7”

but the more procedural ‘arithmatic’ reading is:

take x, multiple by three, add seven and this gives y

In programming languages this is of course the normal semantics … and can give rise to confusion in statements such as:

x = x + 1

This is both confusing if read as an equation (why some programming languages have := read as “becomes equal to”), but also conflicts with the left-to-right reading of English and European languages.

COBOL which was designed for business use, used English-like syntax, which did read left to right:

ADD Tiree-Total TO Coll-Total GIVING Overall-Total.

Returning to Jewish mathematicians, does the right-to-left reading of Hebrew help in early understanding of algebra?  But if so then surely there should be many more contemporary Arab mathematicians also.  This is clearly not the full story, but maybe it is one contributory factor.

And, at the risk of confusing all of us brought up with the ‘conventional’ way of writing equations, would it be easier for English-speaking children if they were introduced to the mathematically equivalent, but linguistically more comprehensible:

3x + 7 = y

3. The Russians did not send a team to the IMO in 1978.  There were three explanations of this (i) because it was in Romania, (ii) because the Romanians had invited a Chinese team and (iii), because the Russian national mathematical Olympiad had also produced an all Jewish team and the major Moscow university that always admitted the team did not want that many Jewish students.  Whether the last explanation is true or not, it certainly is consonant with the levels of explicit discrimination in the USSR at the time.

# mathematics goes reality TV!

In 1978 I was on the British team for the 20th International Mathematical Olympiad (recollections of the trip). It was in Romania and the event was prime time news … and I was one of a group interviewed for the news of the event. the following year the 21st IMO was held in London and there was no press coverage that I found whatsoever. OK mathematics is hardly a spectator sport, but the complete British lack of interest in anything remotely intellectual was disturbing.

But now … nearly 30 years later … perhaps things are changing. On Sunday BBC2 are showing a 90min documentary about the olympiad team. Maybe maths will get sexy!

Beautiful Young Minds1
BBC2 Sun 14 Oct, 9:00 pm – 10:30 pm 90mins
Beautiful Young Minds tells the story of some of the brightest mathematical brains of a generation. Each year, exceptionally gifted teenagers from over 90 countries compete for medals at the International Mathematical Olympiad. The film follows a group of brilliant teenagers as they battle it out to become the chosen six selected to represent the UK.
