algebra

SHUDDER. I was terrible at maths at school, and even the thought of algebra still fills me with horror. But, I’m all for feeling the fear and doing it anyway (except when it comes to sharks, which I’m also very scared of), which is why algebra is my word of the week. Also, it has an interesting backstory which isn’t, as you might assume, anything to do with Greek.

Before we get into that though, let’s have a quick refresher for anyone who, like me, can only vaguely remember their school days. Algebra is a branch of maths that focuses on studying mathematical symbols and the rules for manipulating those symbols to solve equations (that just sent another shiver down my spine), which apparently makes it easier to solve complex problems. Here’s a super-simple algebraic equation:

2x + 5 = 11

And here’s a really not simple explanation for how to solve it (thanks to my robot overlord, sorry ChatGPT, for doing the maths for me. Also, feel free to skip to the next paragraph if you just don’t care):

In this equation, ‘x’ is the variable, and the objective is to find the value of ‘x’. First, we isolate the variable ‘x’ by subtracting 5 from both sides of the equation:

2x + 5 - 5 = 11 - 5

This simplifies to:

2x = 6

Next, to isolate the variable ‘x’, we divide both sides of the equation by 2:

(2x)/2 = 6/2

This simplifies to:

x = 3

So, the solution to the equation is x = 3.

For anyone who’s still here, here’s why algebra is called algebra. The word comes from the Arabic phrase ‘al-jabr wa'l-muqabala’, which means ‘reunion of broken parts’ or ‘restoration and balancing’, referring to the process of restoring balance by transferring terms from one side of an equation to the other. Nice, right?

This rather romantic-sounding term was coined by the Persian mathematician Muhammad ibn Musa al-Khwarizmi in the 9th century. I have mixed feelings about Al-Khwarizmi because he came up with this lovely phrase (like), but he also pretty much invented algebra in his book ‘Kitab al-Jabr wa'l-Muqabala’ (don’t like). Just to make things even more complicated, his book was translated into Latin in the 12th century, which is when the west adopted the term (and discipline) ‘algebra’ and ruined many school children’s lives for centuries to come.

(Muhammad ibn Musa al-Khwarizmi also gets a prize for best job title ever: ‘astronomer and head of the library of the House of Wisdom’. Tough to fit on a business card though.)

assassin

An assassin is someone who murders prominent people like politicians (I’m saying NOTHING) or royalty. You know that. But where does the word come from? And why has it got so many goddamn ‘s’s in it? Well, the word ‘assassin’ derives from has even more ‘s’s: hashshashin (it is physically impossible to not sound drunk when attempting to say this).

If you’re thinking ‘hashshashin’ sounds a bit marijuana-y, then you’re bang on – it means ‘hashish eaters’. But how did stoners become associated with political killers? Let me start by taking you back a thousand years or so to the mountains of Persia and Syria. Why? Because this is where we find a Muslim sect called the assassins, carrying out covert murders of both Muslim and Christian leaders they considered enemies of their state. According to my usual not-very-in-depth research, the assassins were pretty hardcore, and their missions were often suicidal. Their preferred method of killing was with daggers, and, over nearly 300 years, they took out hundreds of people including three caliphs and a ruler of Jerusalem.

This unassuming chap is Lee Harvey Oswald who assassinated JFK (OR DID HE?) on 22 November 1963.

So how did the link between the word ‘assassin’ and ‘hashish’ come about? Disappointingly, historians say there’s no real evidence that they smoked any hashish at all (which is probably a good thing as they’d never have got any murdering done with all the giggling and going to the 24-hour garage for snacks). One theory is that because ‘hash’ means ‘weed’, the name comes from the idea that they cut down their enemies as easily as if they were weeds. Whatever the answer, we can apparently blame Marco Polo for popularising the link between the two.

The earliest known use of the verb ‘assassinate’ in print in English was in a pamplet by one Matthew Sutcliffe printed in 1600. Sutcliffe was an English clergyman, academic, lawyer and ‘controversialist’ (according to Wikipedia). The pamplet was called A Briefe Replie to a Certaine Odious and Slanderous Libel, Lately Published by a Seditious Jesuite (I don’t know if this was controversial or not). Five years later a little-known writer by the name of William Shakespeare introduced ‘assassinate’ to the masses (sorry Matt), in Macbeth.
