Year 12’s Shankar Vallinayagam took his place on the stage alongside professional mathematicians as a speaker at the 2022 Maths Fest.
Shankar was among 45 Year 12 mathematicians from QE to attend the annual series of lectures at The Royal Institution in London.
He was selected as a speaker after his video submission for a related Mathematics competition – the Maths Slam – was picked as one of the winning entries by the judges. He was one of four winners who gave presentations on the day.
Mathematics teacher Kirtan Shah said: “I know that many of our boys not only enjoyed the day, but also really relished the opportunity to learn about fascinating aspects of maths and its applications in the real world. As one of our students, Haipei Jiang, put it afterwards ‘It was great to be in an environment where so many other students appreciated really cool maths.’”
As in previous years, the day was chaired by Mathematics YouTuber and ‘stand up mathematician’ Matt Parker.
The day began with Professor Jennifer Rogers, Vice President for Statistical Research and Consultancy at PHASTAR, the London-based international biometrics contract research organisation, giving a talk on Stats to Save the World. As the lead statistician on a treatment trial for Covid-19, she explained the importance of sample size for clinical trials and the factors which help to determine how large a sample size should be.
Next was internet mathematician and public speaker James Grime, who talked about hidden Mathematics behind the digital world, from looking at how wifi signals are communicated to how cryptanalysis was used to break codes from Germany’s Lorenz cipher machines during World War II.
Host Matt Parker explained that our brains naturally think of numbers using a logarithmic scale, yet the modern world uses a linear system of numbers – which can easily confuse people in understanding how big large numbers actually are.
Puzzle expert and author Rob Eastaway looked at ‘fairness’ and ‘guilt’, telling the audience that chimpanzees have been seen to grasp the concept of fairness, refusing a treat if they felt they were receiving preferential treatment over their fellow chimps.
Mathematics teacher and examinations expert Nicole Cozens shared her top five tips for exam success from her experience of marking papers for 15 years, starting with: Always quote the formula first when using it in a question – this is to show the examiner that you know the formula, even if you end up making a mistake in how you use it.
Ben Sparks, musician and star of the educational YouTube channel, Numberphile, ended the day by explaining the Mathematics of the notes in an octave and sharing how sine waves, trigonometry and complex numbers are used to make noise-cancelling headphones work.
Shankar’s short talk was entitled The Alexander Horned Sphere: he came across the sphere, an object found in the branch of Mathematics known as topology, during his research for his Extended Project Qualification (EPQ) dissertation. Mr Shah said: “His talk interested the audience and got them thinking about why we shouldn’t say something is ‘obviously true’ in maths without proof.”
During breaks, the boys visited the event’s Maths Village, where they could enjoy mini-mathematical activities and meet people who use Mathematics every day at university and in commerce.
The boys were accompanied by Mr Shah and his fellow Mathematics teachers, Deljoo Mahdmina and Heena Haq.
Reflecting on the Maths Fest afterwards, pupil Rajveer Mukherjee said: “I particularly enjoyed it as although the talks were incredibly interesting, they also proved to be accessible to all, while leaving room for further research into the topics.” For his part, Abir Mohammed loved the opportunity to meet “renowned maths celebrities”.
In the final of the competition, which was modelled on ITV’s The Chase, the winning teams from the Year 7, 8 and 9 heats each competed against a teacher ‘chaser’ as they tried to make it through to the last round.
Headmaster Neil Enright, who came to the final, said: “This event was great fun and was for a very good cause. My thanks go to our Sixth Form charity team for organising it and to all the members of staff involved, including the ‘chasers’ who cheerfully put their credibility on the line for charity!
The lunchtime final in the Main School Hall followed preliminary rounds held during lunchtime breaks over the previous week.
Shriram paid tribute to the role of charity team captain, Lourdes Kumar, of Year 12, and of Assistant Head (Pupil Involvement) Crispin Bonham-Carter and Extra-curricular Enrichment Tutor Katrin Hood in liaising with the recipient charity, Teach Sri Lanka. Ms Hood was also the host and quizmaster.
With the 2021 event moved online because of the pandemic, this year’s convention provided an eagerly awaited opportunity for the School’s newest alumni to meet face-to-face with Year 12s thinking about following in their footsteps.
Most of the OEs attending the convention are currently in their first years on sought-after degree courses at leading universities, including Oxbridge and the Russell Group institutions.
Then, in the afternoon 16 visiting old boys headed for the Martin Swimming Pool for the water polo friendlies.
The pair took on Old Elizabethan challengers Ravi Karia and Jathieesan Umaasuthan (both OE 2011–2018), who argued against the motion, This House would ban all non-electric vehicles.
“Not only was it the first time some had worn black-tie, but I understand that one boy’s clip-on bow tie had been manufactured only that morning using a 3D printer!” added Mrs Mayer.
The visitors were formally proposed by the 2021 School Captain, Siddhant Kansal, of Year 13, while the Elizabethan Union was proposed by Izzet, who last month took up a new post with international law firm Kirkland & Ellis.
PE teacher Oliver O’Gorman said: “This is an extraordinary achievement: we believe it’s the first time in QE history a pair has made it to a national Fives final. I am beyond proud of this pair, who have put in non-stop work this year to deservedly claim this title.”
Other QE achievements in the sport this year have included Year 10’s Rishabh Bhatt and Dinuk Dissanayake reaching the final of the national U15 qualifying round after beating Aldenham in the quarter-final and Ipswich School in the semi-final. They were eliminated 2-1 by a pair from Mill Hill School in the final.
