So people, what did the positive charge say to the negative charge? Buzz off! – I know, you’re all saying: “**Ohm** my God, that was bad. **Watt** made you tell that joke?” – and while I can think of **amp**‘le reasons, the main one is because today, I’m going to talk about static electricity!

And you thought it was safe to go out again. No, circle theorems are not over – we’ve got to know how to prove them as well, much like many different things in Maths. And although only one is really likely to be on the exam, we’ll cover all of the proofs for the theorems that have even the slightest chance of coming up – to see these, continue reading…

There’ll be an in-depth explanation of moments coming along soon, but for now, we’re doing a series of posts to jog your memory on simple equations, their units, and how to rearrange them… So, if you’re stuck for an equation, then first up: the moment equation…

There are two types of chromatography. Today, we will be discussing paper chromatography, also known as ‘simple’ chromatography – for that very reason: it’s simple! As you may have guessed, paper chromatography is carried out on paper. Chromatography is used to separate different mixtures into their separate components – for example: you can separate inks, food colourings and dyes.

Pardon the pun – you’ve probably guessed what we’re talking about here. If you haven’t, then let me tell you that it’s the perfect tense – another one of those 3 past tenses, but with more meanings than you might expect. But what does it mean? And how do you form it? To find out, read on…

Circle theorems. Ah, what a wonderful part of the Unit 3 Maths exam. Or not, as it may be. Confused between your cyclic quadrilaterals and alternate segments, or between your chords and your tangents? Don’t worry, because here, I take the plunge and give you a crash course in circle theorems. To find out, read on…

Salt is something we’ve come familiar with in every day life, but how exactly is it made? That particular question is almost certainly one that you’ve never really asked yourself, but let us consider it anyway… In basic terms, a salt is the produce of an acid and an alkali mixed together. But how exactly does that happen?

*Sorry, I couldn’t think of an appropriate image for this topic!*

Bounds? What are bounds? Bounds are actually quite a simple idea, but sometimes they can take a while to get your head around… So, with this in mind – let’s go!
