Phil MacFarlane: Why do so many physicists go into the financial services sector? The talk will summarise the techniques to calculate the value of financial derivatives and how to price risk. In particular it will look at how techniques familiar to physicists - entropy, quantum mechanics, etc - have parallels in pricing financial products. June 12
How does that work? Together we'll try to work out how a piece of Victorian engineering works. July 10
Dave Waymont: Making a radio-telescope. This talk describes the design of the telescope, the numerous problems encountered, and the first results. 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 mathsphys@dorchesteru3a.org.uk for further information.

Lastly, a bit of fun ...
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.
