In her equally delicious follow-up to Geology Is a Piece of Cake (2017), Coppens as soon as once more retains the concentrate on the meals—linking introductions to seven elementary ideas of geometry, together with “Symmetry,” “Tessellations,” and “Angles,” by rapidly turning every matter pie-ward: “How does rotational symmetry relate to pie?” “How do polygons relate to pie?” “How does Pi (π) relate to pie?” The illustrations supply a equally enlightening (to not point out mouthwatering) combine of easy diagrams and shade images (most by the creator herself) of fantastically adorned pies, sliced or entire as required for demonstrative functions. Clear, easy line diagrams complement these images and ably assist to combine the content material. A dialogue of proper, complementary, acute, and obtuse angles (and extra) yields explorations of each equitable slicing and relative urge for food measurement. Recipes? After all…eight in all, starting from appetizer-sized samosas and a savory quiche to a butterscotch pie and a lattice-topped apple masterpiece (demonstrating parallel and perpendicular traces, natch). All include detailed directions, although for all however the closing array of miniature berry pies, pre-made dough or crusts are beneficial. The creator closes with 20 difficult assessment questions (about geometry, however solid in pie-centric language) and a closing picture gallery labeled “Simply Desserts” to drool over.
