Maths and Physics Group
Equation of the Month: Euler-Masheroni constant. This constant, which is roughly 0.5772, occurs in various mathematical contexts, but most notably in analysis and number theory. It is not known if this constant is irrational, algebraic or transcendental.

Dave Waymont: AC Circuits The talk will cover electrical impedance and where AC circuits become interesting: filter design Jun 11
John Ibbitson: Modern Monetary Theory Modern currency issuing economies don't work the way you think. In classical economics money is simply a number in the economy. Modern Monetary Theory claims the of role money is fundamental. Jul 9
Phillip McFarlane: The Thermin A talk about the musical instrument you don't touch - and which is fiendishly difficult to play. The schedule may change, so please check again closer to the date

The Maths and Physics Group meets on the 2nd Wednesday of the month in the Lower Classroom at the Holy Trinity Parish Centre from 9.30 am until 10.45 am. Most meetings consist of one of our members giving a talk on a subject of their choice, but we are open to suggestions. There is also a WhatsApp group for people to ask each other questions, or to point out interesting news articles or books they've read.
New members are very welcome. You don't need to be Einstein be a member! You just need to be interested in maths or physics (or engineering, technology, astronomy ... ). Contact [email protected] for further information.

Please make all the usual assumptions, and don't worry if you can't solve the problems! Solutions can be found in this pdf.
The questions are best viewed on a desktop as they may contain pictures that cannot be scaled easily for a mobile.
Two new problems will appear next month.
