Schedule

10:00 AM - 10:30 AM  Registration
10:30 - 11:30 AM Speaker: Alannah Hallas (UBC Physics & Astronomy)
Title: Superconductivity: From MRIs to Magnetic Levitation
Abstract: Superconductors are materials that can carry electricity with zero resistance, unlocking remarkable possibilities for technology. They already play a critical role in medical imaging through MRI machines and in particle accelerators that probe the fundamental nature of matter. Even more futuristic applications, like frictionless magnetic levitation and lossless power transmission, show the transformative potential of these materials. This talk will explore the science of superconductivity and its journey from discovery to cutting-edge innovations.
11:30 AM - 12:30 PM Lunch break
12:30 PM - 1:30 PM Speaker: Colin Macdonald (UBC Mathematics)
Title: Interpolation, a witch, and poles in the complex plane
Abstract: The approximation of functions is fundamental in mathematics. Polynomial interpolation---such as drawing a straight line segment between two points---is a useful approximation in applications, some of which we'll discuss.  Using basic ideas of roots (x-intercepts) of polynomials, we'll look at a beautifully-constructive mathematical proof.

Following some computer experiments and a little bit of history, we'll see how studying imaginary numbers can help explain why interpolation works well for some problems, but not for the Witch of Agnesi.

Registration

Registration will be $20 for the semester.

Directions

Archimedes Talks will be held at the Irving Barber Learning Centre (1961 East Mall) room 261.

Bus Travel
UBC is the terminal stop for many bus routes. The Irving K. Barber Learning Centre is a short walk from the main bus loops.

By Car
The North Parkade is the nearest parking garage, 6115 Student Union Boulevard. This is also a convenient location for dropping students off. Note, however, that parking is not free.
