Maths and Physics Group
Equation of the Month: Bayes’ Theorem. This theorem in probability is easy to prove. When fitting model parameters to some measured data the theorem reads “the probability of the model parameters given the data is proportional to the probability of the data given the model parameters multiplied by the a priori probability of the model parameters.” The answer therefore depends on the prior probability - a fact that has caused much controversy.

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.
