Advent Oil & Gas: Fossil fuels – what’s in a name?

It’s probably not escaped your notice that this series is about ‘oil and gas’, but you’ll also have heard a lot about ‘fossil fuels’ – they’re even in the title of this article!  What’s the difference?  The answer is somewhat complicated: fossil fuels are often oil...

Filter paper

Advent Chemistry: Filtration

You all know what a filter is. It’s that thing you make coffee with. It’s a way of seperating solid particles from liquids. A sieve is a filter, if not a very fine one. A teabag is a filter with leaves inside. It is one...

The Turing machine

Advent Computing: The Turing machine

If we’re going to have a series of posts about computer science, it’s probably helpful to define what a “computer” is. So let’s do that. The standard academic definition of a computer is what’s called a “Turing machine”. It goes a little bit like this:...

Advent Biology: A summer of Bats

A late entry from me, and very much self indulgent…so Ecology, then. My absolute favourite part of ecological studies is the fieldwork- I’m happy to be out in all weathers, in any gear, with scientific equipment ranging from GPS trackers to a bamboo pole and...

Advent Chemistry: Getting Started

So here we are, day one, and first things should come first. Let’s talk about measurement. Measuring out your reactants is fairly vital to doing chemistry. You can’t get very far if you don’t know what you’ve got and how much of it. So you...

Advent Oil & Gas: Power and energy basics

It’s generally known that oil and gas are pretty big industries but it’s important to quantify exactly how big.  As this is the first article of Advent I’ll take the opportunity to run through some common units, and use them to get to grips with...

Advent Finish Line

89 articles, 24 days, 8 topics, and a partridge in a pear tree (Which was actually the name for a kind of bamboo bird cage, rather than a fruit tree). Thank you for everyone who was reading, and especially everyone who was writing, every single...

Advent Roller Derby: Post-bout curry

The final whistle blows, the head ref signals the end of the game… so what happens now? (No, don’t start singing that song from Evita!) There is often a lot of hugging straight after the end of a bout. Skaters hug their team-mates, their opposition,...

Advent Chemistry: N-glucoside

Well, it’s the 24th of December, the last day of Advent. We’ve looked at some of the fundamentals of organic chemistry: bonds, functional groups, resonance (“shuffling electrons around”), aromaticity, chirality, conformation (shape) and stability, along with some other aspects of chemistry like ionic bonds and...
