One aim of the author included to instill math sense rather than rote knowledge. This did not come through in the writing. Nor did it make me think of math in a different way. It simply went through formulas and graphs for addition, subtraction, multiplication, division, and some algebra. There were some new ways of doing things (or perhaps I forgot) and british phrases. ...more

From there, the narrator goes through the historical developments of geometry. It combines biographical anecdotes and snippets of theory. As in art, many thinkers took pieces of a previous theoretical approach and gave new interpretation. Humanity would have more research to use if religion had not come around to kill people, torture people, and sometimes burn works of original thinkers. I love that people made abstract systems to the physical world around them. It is pretty neat.

Most of the theory was readable. I could follow the general ideas: Euclid put math formulas to geometrical shapes-understand distance, invention of graphs, Gauss' rejection of two dimensional formulas in favor of multi dimensions, and Einstein's theory of relativity- the relationship between objects, space, and time is relative to the framework which varies. I don't understand the attempts of the book to explain quantum mechanics or string theory. Furthermore, it is difficult to imagine how these (beasite boys intergalactic in head) "other dimension" formulas will have real life implications. Lots of the Greek math provided a basis for understanding everyday inventions such as electronics and magnetism.

It was wonderful to read the first few pep talk chapters of this book. Sarah Flannery felt confident in math because her math professor father David, had presented it in an accessible manner to his children. She provides word problems and simple logic to try to lure in non math oriented thinkers. Philosophically she states math is a great equalizer that is refreshing because anyone can try and bring new insight. Then, she goes on to explain some math behind cryptography. There are three dense chapters or just my personal thickness chapters. In any case, I got some superficial ideas behind coding and the applications for computers. Sarah first won an award in Ireland’s Young Scientist contest. Her curiosity deepened and led her to expanding her project. She was invited to several more competitions and lectures. Portions of the writing are directly from her diary. Some parts of from her math journals which trace her thinking. It was a fun read about a subject to which I am normally averse toward.
