"The Wonders of Flow: Understanding Fluid Dynamics ABCs Through Play" Ryōzō Ishiwata / Mitsumasa Nemoto / The Japan Society of Mechanical Engineers Price: ¥1012 I've only read it once, so it's in very good condition. There's a slight crease at the top of the back cover, but there are no stains, folds, or writing on the main body. Shipping will be free and anonymous. I am listing many books from the same series. If you purchase them together with other books, I will offer a discount on shipping. #RyōzōIshiwata #Ryōzō_Ishiwata #MitsumasaNemoto #Mitsumasa_Nemoto #TheJapanSocietyofMechanicalEngineers #book #nature/physics"
