Michaelmas 2014 Termcard

All talks are to be held in the Winstanley Lecture Theatre, Trinity College, and will begin at 8.30pm with port and orange juice from 8.15pm. With the exception of the first talk, which is open to all, talks are for members only; non-members may join at the door.

Monday, 13th October: Dr. Piers Bursill-Hall (DPMMS):
Pythagoras Never Existed. You Have Been Lied to, and All School Maths is False.
Everyone in the Universe has heard of Pythagoras, and knows about the Theorem, and how the Pythagoreans discovered that root-two is irrational. And all of that is false: in fact, just about everything you have been told about ancient mathematics is wrong and rubbish. Hey: Welcome to Cambridge.

Monday, 20th October: Dr. Perla Sousi (Stats Lab):

Monday, 27th October: Dr. Julia Gog (DAMTP):

Monday, 3rd November: Dr. Daniel Baumann (DAMTP):
The Quantum Origin of Structure in the Universe
Quantum fluctuations in the vacuum play an important role in fundamental physics. In this talk, I will show that these fluctuations get stretched to cosmic scales if the early universe experienced a period of inflationary expansion. Using little more than the quantum mechanics of a simple harmonic oscillator, I will compute this effect and explain how it provides the primordial seeds for all structure in the universe. I will show how these predictions compare to recent observations of the cosmic microwave background. Finally, I will speculate about the physical cause for the inflationary expansion.

Monday, 10th November: Dr. James Cranch (University of Sheffield):
Which Real Numbers are Pleasant?
Every well-educated fresher has already been indoctrinated with the right answer to this question: reals are either algebraic or transcendental. Algebraic numbers are obviously fantastic. By contrast, the transcendental numbers are utterly hideous and deserve no attention whatsoever, with the two exceptions of pi and e (bless their little cotton socks). Contrary to this received opinion, I’ll explain why it should be a major goal of 21st-century mathematics to reclaim more of the reals for explicit use by mathematicians, and I’ll tell you about some difficult problems that need to be solved along the way.

Monday, 17th November: Prof. Benjamin Allanach (DAMTP):
Possible Hints for Supersymmetry at the Large Hadron Collider
The Large Hadron Collider is about to start operation again at a higher energy at the beginning of 2015. I shall introduce the machine, particle physics and the discovery of the Higgs boson. Standard theory predicts that the quantum fluctuations should make the Higgs boson much heavier than it is observed to be, but a speculative theory of particle physics (supersymmetry) explains why the quantum fluctuations are small. This theory predicts a host of new particles for the LHC to find. There were a few small anomalies in LHC data already that can be interpreted as the production of certain supersymmetric particles. Such interpretations are ready for further experimental testing next year.

Monday, 24th November: Dr. Nathanaël Berestycki (Stats Lab):

Monday, 1st December:
Mathmo Call My Bluff
Come and celebrate Christmas with the TMS’s annual Call My Bluff event. Watch a Freshers’ Team take on a team drawn from the combined might of the rest of the university in a competition in which mathematical knowledge takes a second place to the ability to hold a good poker face.

Dr. Rachel Camina, Conjugacy Classes in Finite Groups

Speaker:Dr. Rachel Camina (DPMMS):
Venue: Winstanley Lecture Theatre
Time: 10/03/2014 20:30, drinks from 20:15

If we know the sizes of conjugacy classes in a finite group what does this tell us about the group? We will discuss this problem.

Dr. Mike Tehranchi, Fun with Gaussian Measures

Speaker:Dr. Mike Tehranchi (Stats Lab):
Venue: Winstanley Lecture Theatre
Time: 03/03/2014 20:30, drinks from 20:15

The standard normal distribution is probably most famous for its starring role in the central limit theorem. This talk will explore useful and unexpected properties of normal distributions, also known as Gaussian measures, and how they arise in a variety of contexts. A few old open problems will also be discussed.

Dr. Helen Mason, Our Active Sun

Speaker:Dr. Helen Mason (DAMTP):
Venue: Winstanley Lecture Theatre
Time: 17/02/2014 20:30, drinks from 20:15

The Sun should be at the peak of its activity cycle, but actually it has been rather feeble. Several solar space observatories have been watching the Sun over the past few years: SoHO, Stereo, Hinode, SDO and IRIS . We now have high spatial and spectral resolution images of the Sun, with a high cadence. This talk will review what we have learnt about the active Sun, in particular what we know (and don’t yet know!) about solar active regions and flares, and how they might affect the Earth’s environment (via space weather).

Speaker:Prof. David Tong (DAMTP):
Venue: Winstanley Lecture Theatre
Time: 10/02/2014 20:30, drinks from 20:15

A story of geometry and particle physics.
