Blood and the respiratory system

...changes colour when bound by O2, oxygenated blood is often depicted as bright red, whereas deoxygenated blood is shown as blue in colour. This course doesn't explore how blood circulates around the body, but it is important to note that the lungs differ from other organs in that deoxygenated blood is carried to the lungs via arterioles (and larger arteries), whereas...

Grammar matters

...changes affect meaning. For example, if we left out the apostrophe in Let’s, which indicates that the u in us has been left out, there would be no loss or distortion of meaning. In this case, incorrect grammar would only be a superficial problem: it might make us question the attention to detail of the text producer, or even cause the reader to make negative social...

Exploring criminology: problem-solving courts

...change. It started one way, and it continued that way. Obviously, as the time goes by, things get better with yourself. You get more and more clean. So things obviously go off a bit with testing, et cetera, et cetera. But generally, it was the same experience the whole way through. What worked really well with FDAC is they keep you busy, they keep you very, very busy. So...

How does rugby provide a focus for South African unity?

...change into democracy, and then conquered the world in rugby. South Africa was united, and things looked very promising.

Rugby fields became a virtual Colosseum of dreams. Lack of transformation...

Who will lead Britain out of the European Union

...change people’s minds rather than focusing on getting existing eurosceptics out to vote. And there is evidence to support that approach. British public opinion towards European integration can be summarised as largely indifferent and mostly shallow. That makes it highly erratic. Famously, the 1975 referendum moved opinion from two-thirds in favour of a “No” to...

How we found gravitational waves

...change lengths, the laser beams take a different time to travel through them. This means that the two beams are no longer “in step” and what we call an interference pattern is produced – hence the name interferometer. The changes in the length of the arms are actually tiny – roughly one million millionth the width of a human hair. This is because the signal from a...

What's so exciting about gravitational waves being discovered?

...change in the diameter of the Earth compared to the 1m change due to a tidal bulge. What can gravitational waves be used for? Given that these ripples are so small and so difficult to detect, why have we made such an effort to find them – and why should we care about spotting them? Two immediate reasons come to mind (I’ll leave aside my own interest in simply wanting...
