Author Leah Elson, scientist and science communicator, answers questions posed to her through an online community. The 103 questions she answers are grouped into five categories (Biology, Chemistry, Physics, Human Physiology, and Space) and range from 'What is the function of nipples on men?' to 'Why isn't Pluto a planet anymore?'. Her replies are short, concise, and humerus... (ha, ha, see what I did there?). She has also provided an illustration for each response which she drew herself... in crayon. The questions vary from the simple to the complex, yet Leah always makes a good attempt to provide explanations accessible to non-scientists. There are a few, however, that are either too complex to be dealt with in the short one or two pages she has allotted for each one, and in some cases (really only a couple that I came across) obvious errors or 'mis-explanations'. One of these is her answer to why a feather and a hammer hit the ground at the same time when dropped on the moon (there is no mention of the importance of inertia). Another is her illustration for electric current in the very next question (she has not distinguished between electric current and electron flow).
This book may appeal most to the under-20 crowd... Leah seems personable, funny, and also uses some 'colourful' language from time to time (inconsistently blocking out letters but then using the full spelling in other places). It is a quick read, and overall a good effort at promoting science as an important way of answering common questions that many of us have.
