Probability

Image from lecture

The first of six 'Probability' lectures we are showing, taken from the first year undergraduate course, is now available to watch.

The First Year Probability lectures are for students of Mathematics, Computer Science and joint degree courses between Mathematics and Statistics and Mathematics and Philosophy. First year lectures are supported by lecture notes and complemented by one problem sheet for every two lectures, which students are asked to solve in preparation for discussion in pairs with their tutors in tutorials. 

Lecture 1 takes the intuitive notion of randomness (and perceived randomness) in the real world and introduces mathematical models, in which events that may be observed are captured as sets of possible outcomes to which we can assign probabilities. 

This lecture joins another 85 undergraduate lectures that can be watched via the playlist.

Roger Heath-Brown appointed OBE in 2024 New Year Honours List

Image of Roger

Oxford Mathematician Roger Heath-Brown has been been appointed Officer of the Order of the British Empire (OBE) for services to Mathematics and Mathematical Research in the 2024 New Year Honours List.

Roger Heath-Brown is one of the foremost analytic number theorists of his generation. His important works on prime numbers and related topics include, among many others:

- "Heath-Brown's identity", an important way of decomposing the primes into multilinear pieces, used in many other works such as Zhang's work on bounded gaps between primes

- There are infinitely many primes of the form x^3 + 2y^3 (currently the sparsest natural sequence where one can find primes)

- if a is coprime to q, there is always a prime a (mod q) of size < q to the power 5.5

- at least one of 2,3,5 is a primitive root modulo infinitely many primes.

His contributions to solving equations in integers and rationals include, for instance:

- every nonsingular cubic form in 10 variables has a rational point (and 10 is best possible)

- every cubic form in 14 variables has a rational point

- development of "the determinant method"

- breakthrough quantitative results on the number of rational points up to a given height

Roger Heath-Brown was educated at Cambridge (a student of Alan Baker) and moved to Oxford in 1979. He was made FRS in 1993, and was twice a speaker at the International Congress of Mathematicians. He remained at Oxford throughout his career, first at Magdalen College and then, upon being promoted to a personal statutory professorship in 1999, at Worcester College. He retired in 2016. Among his many graduate students was James Maynard, who was awarded the Fields Medal in 2022.

Roger said: "Naturally I am thrilled to receive this honour. It is a reflection of the ever growing importance of mathematics in modern life. Indeed, I have been delighted to see the corresponding growth in the subject at Oxford over the past 40 years, and also within Number Theory - my own research area. I would like to take this opportunity to acknowledge the friendship and support of my colleagues both at Oxford and across the globe. They have made my work a pleasure."

A puzzle for Christmas - the answer

James Munro in Christmas jumper

Here's the answer to yesterday's Christmas puzzle. If you missed it, you can find it here although James Munro recaps it in the answer video below.

In a roasted chestnutshell, it's a story of three kings bringing gifts (sound familiar?). However, they are not all telling the truth. Your job is to work out who is and who isn't telling the truth and what gifts they have really brought.

Not too taxing, easy to digest, just follow the star. Merry Christmas.

A puzzle for Christmas

Opening shot of video - James Munro in Christmas jumper

Here's a Christmas puzzle for mathematicians and non-mathematicians alike. Especially non-mathematicians.

Three kings each arrive with a gift; one has brought gold, one has brought frankincense, and one has brought myrrh (and no-one has brought more than one gift).

The first king, Balthasar, says “I have brought gold.”

The second king, Caspar, says “I have not brought gold.”

The third king, Melchior, says “Caspar has not brought gold”.

Suddenly the angel Gabriel appears with the following divine intervention; “beware! One of the kings has brought myrrh and is lying. The king with frankincense is telling the truth...”

To find out more watch the video below. James Munro is our guy in the festive jumper. Answer tomorrow, same time, same place.

Conrad Shawcross exhibition extended

Image of Conrad and artwork

What was your highlight of 2023? 

Without doubt, Conrad Shawcross' exhibition of over 40 mathematically inspired artworks has been one of ours, not only attracting visitors to our building who would not otherwise visit a mathematics building, but also inspiring our mathematicians to think about their own field and work. A gallery of art in a gallery of minds.

So if it was a highlight in 2023 why not reprise in 2024? We are delighted that Conrad has agreed to extend the 'Cascading Principles' exhibition until the summer of 2024. You are all very welcome to visit as most of the works are publicly accessible. Please email @email to arrange a full tour (some of the items are in the private, working parts of the building).

You can read more about the exhibition here

And you can watch a series of four lectures focussed on the exhibition where artists and scientists compare notes on creativity.

The Conrad Shawcross exhibition is generously supported by XTX Markets.

Oxford Mathematics merchandise now online

Beanie

When we needed a design for our Oxford Mathematics merchandise, we thought we didn't have a badge or coat of arms. Until we realised we did. At the entrance to our building is the Penrose tiling, our mathematical coat of arms.

So our designers, the excellent Stephane Harrison and his team at William Joseph, came up with the idea of the exploding tiles. They have now become our unofficial logo (if you can have such a thing), on all our merchandise and materials.

You can now sample our Penrose-inspired swag, from hoodies and fleeces to caps and beanies. And its mathematical Black Friday from today until 27th November. You'll get 15% off by using the code: GREEN15.

A Mathematical Journey through Literature - Sarah Hart

Banner for lecture

In this Oxford Mathematics Public Lecture, Sarah will explore the many connections between mathematics and literature. She'll show the hidden mathematical structures behind everything from poetry to novels, and reveal some of the beautiful mathematical imagery and symbolism in fiction, from simple fairy tales to classics like Moby-Dick. Her goal is to show that not only are mathematics and literature inextricably linked, but that understanding these links can enhance our enjoyment of both. 

Sarah Hart is the the Gresham Professor of Geometry at Gresham College, Professor of Mathematics at Birkbeck, University of London, and author of Once Upon a Prime: the Wondrous Connections between Mathematics and Literature.

Please email @email to register to attend in person.

The lecture will be broadcast on the Oxford Mathematics YouTube Channel on Thursday 14th December at 5pm and any time after (no need to register for the online version).

Mathematics Admission Test (MAT) 2023 - update

Image of 'trees from MAT

The delivery of this year’s Mathematics Admissions Test (MAT) has caused widespread distress and difficulties, most especially for the candidates themselves. The Oxford Mathematical Institute would like to apologise for this distress, and assure everyone that our priority is to ensure that no one is disadvantaged during the admissions process. We would also like to thank everyone who has provided feedback so far, whether via the special consideration forms or via email and social media.

We have decided on the following steps:

The Mathematical Institute will offer an additional test to candidates who submit a special consideration form after experiencing disruption when taking the MAT on 19 October, whether they applied to Oxford, Imperial or Warwick Universities.

The additional test will be optional; candidates are not required to take it if they are happy with how the MAT went for them on 19 October. For candidates who suffered disruption and wish to take the additional test, that test will supplement the information we already have.

On the 3 November, we will send out invitations for the additional test to all candidates who submitted a special consideration form, or who are identified as having experienced disruption, as well as to test centres where that disruption took place. We recognise that some candidates may not have access to information via schools or centres - we are doing all we can to identify them. 

The invitation will ask candidates to complete a simple form to register (by noon on Friday 10 November) for the optional additional test which will take place on Tuesday 14 November at 09:00 GMT. (Candidates in the USA for whom 09:00 will not work will be identified and contacted separately).

The additional test will comprise ten multiple-choice questions in the style of (and with the syllabus of) MAT Q1, and candidates will have one hour to complete the test.

Where possible, we would like the additional test to be hosted by schools or colleges; where necessary, remote invigilation will be arranged at home. The additional test will be made available to test centres (or candidates taking the test at home) for printing just before the start of the test on 14 November. The additional test will be administered entirely by the University. 

The Mathematical Institute is marking the MAT test as normal. The majority of candidates experienced no disruption – we do not want to disadvantage those candidates. College tutors (who are responsible for shortlisting) will have access to a candidate’s UCAS form, the results of the MAT test taken on 19 October, and the results of the additional test, if taken, as well special consideration forms. Tutors will take all this information into consideration when deciding whether to shortlist a candidateOxford Mathematics will liaise closely with colleges to manage the situation.

Once again, we apologise for all the disruption. We are doing all we can to make sure all candidates have an opportunity to display their full potential, and no one is disadvantaged.
