Humble Pi: A Comedy of Maths Errors by Matt Parker
My rating: 4 of 5 stars

I was getting ready to give this book 3 stars at the beginning but as I went on I realized that some of these math mental hurdles are driving the covid spread. For starters, many Governors, even 11 months in seem fundamentally unaware of how exponential growth works which is the underlying prediction threat of covid growth. Additionally, most people have very little familiarity with even the basics of how statistics work, useful in understanding all types of science research, for example in vaccine trials. Another example is the Swiss cheese engineering strategy which is also necessary to implement to avoid covid spread but many people and even state governments seem unaware of this.

This book is interesting both for people that do not understand math and for those that do. Those that understand math are usually unaware of how deeply clueless others are but since they make systems for people who do not understand- or at a minimum are fallible humans- humans are likely to screw everything up, possibly with fatal results. It's also a pretty entertaining book as the author genuinely seems to enjoy math and resultant foibles.

“I love the example of someone who starts work at 8 a.m. and by 12 p.m. they need to have cleaned floors eight to twelve of a building. Setting about cleaning one floor per hour would leave a whole floor still untouched come noon.” 

“There is always the chance that something else is influencing the data, causing the link. Between 1993 and 2008 the police in Germany were searching for the mysterious ‘phantom of Heilbronn’, a woman who had been linked to forty crimes, including six murders; her DNA had been found at all the crime scenes. Tens of thousands of police hours were spent looking for Germany’s ‘most dangerous woman’ and there was a €300,000 bounty on her head. It turns out she was a woman who worked in the factory that made the cotton swabs used to collect DNA evidence.”
