People have always yearned to see into the future, to peek around the corner and make sense of what's going on, according to author and mathematician David Orrell. But predicting the future is difficult. ...
A couple of days ago on The Conversation, I set myself up with a task: to defend the usefulness of so-called "useless" maths. Today, that defence continues, with a look at the RSA algorithm.
I once made the mistake of asking a mathematician why he devoted his whole life to maths. "Because it's fun!" he replied wildly, his flabby cheeks beaming with childlike excitement.
