Here are a few of our favourite mathematicians. Some famous, some less famous and one not famous at all. Who's yours?

When it comes to lecturing, there's nothing our professors can't do. They smash courses of 16 lectures with a seamless brilliance which awes our students. There's nothing they don't know. Here's the latest 'Information Theory' lecture from Sam Cohen:

We like to encourage constructive feedback from our students. Sam Cohen is particularly keen on it. We are showing eight of Sam's 3rd year 'Information Theory' lectures. Here's the first (plus feedback):

Andy Wathen concludes his 'Introduction to Complex Numbers' student lecture. You can watch the lecture, and over 100 more of varying degrees of complexity and fun, on our YouTube Channel:

For some mathematicians, it's not just the coffee they drink, but the mug they drink it in.

Mathematics the mind reader. How much monetary pain would you take to deny someone else monetary gain? Marcus du Sautoy issues an ultimatum.

A computer scientist walks into a mathematics department... AI is in Frankenstein mode, worrying about the monster it has created. Even the tech bros seem terrified. So, where does mathematics fit in to AI's future?

Will you still need me, will you still feed me, when I'm 94? Happy Birthday Roger.

What percentage of a mathematician's time is spent in a state of frustration? Or, indeed, any scientist? 10%? 30%? Higher? Oxford Mathematician Torkel Loman puts a number on it.

Pure mathematicians tell us that our 30 billion or so credit, debit and prepaid cards are only safe because of number theory, and prime numbers in particular. But how? James Maynard takes your details in his Sophie Germain lecture. Watch it all:

It's tough, isn't? Probably one of the biggest challenges for mathematicians of all ages. Just how do you talk about your subject to friends and family who aren't mathematical? Our crack team of undergraduates ponder.

One thing you can guarantee about social media is that if you want 20 million views of your films, don't put up clips from student maths lectures. Unless the lecturer is Philip Maini. He's back with 3 lectures on Mathematical Biology. 40 million? No 1:

Remember all those kids who aced maths in school and went on to university to study, shock horror, maths? Well, no doubt they aced it there too because it was just more of the same. No doubt...

We have just put our 100th student lecture on YouTube. But you can watch them all in one minute. Or, alternatively, in about 80 hours:

When Roger Penrose goes for a walk you might expect him to be thinking about cosmology etc. But he isn't. At least not always. Sometimes he is thinking about the walk itself. And the mathematics of it. Because Roger has his obsessions. Like lots of us.

Here's a top tip for aspiring mathematicians from Oxford Mathematician Philip Maini. Be lazy. More advice (and maths) from Philip in his 1st year student lecture on Fourier Series, the latest we are making available.

Artificial Intelligence may not be up for the Fields Medal any time soon, but it may act as an intermediary for mathematicians working on proofs. However, something is lacking for AI to get down to it. Terry Tao looks to the positives. Full lecture:

The professor and the pendulums. We know what will happen when one pendulum swings. But two? 'Oxford Mathematicians and their Toys', episode three, starring Jon Chapman (and the pendulums).

Who are Field's Medallist James Maynard's heroes? Sophie Germain is one. Sophie is 250 this month and her work on prime numbers still matters as James explain in his public lecture. Watch from 5 pm UK today:

Mathematicians are all the same. They look the same. They only like other mathematicians. They only like maths. They did nothing but maths from the age of two. Etc.

When you put a mic on a ruler (we couldn't find a set square) and give it to three of our students...

When we put student lectures on YouTube we knew we'd get comments - positive, negative, funny, not so funny. But we weren't ready for one question. So finally we've decided to answer it. Here's a film about whiteboards. PS: And here's the next lecture:

'Thorough preparation, engaging delivery, active learning, supported by clear, visual-aided, well-structured content.' But enough Google AI. For a good student lecture, how about the human touch? Lecture 4 of Christiana's Mathematical Physiology course:
