## The Calculus Diaries

We’re trying to post up some of the books we’re reading at the Adafruit shop, some are biz related, some science/physics and others might just be for fun. We heard an interview with Jennifer Ouellette talking with Ira Flatow (Science Friday and was at Maker Faire!) – so we picked up the The Calculus Diaries. We’ll post up afer we finish the book – we’re interested in the history of calculus as well as thinking of new ways to help folks with math as they do electronics…

The Calculus Diaries is the fun and fascinating account of her year spent confronting her math phobia. With wit and verve, Ouellette shows how she learned to apply calculus to everything from gas mileage, diet, and the rides at Disneyland, to surfing in Hawaii, shooting craps in Vegas, and warding off zombies famished for tasty fresh brains. Along the way, she proves that even the mathematically challenged can learn the fundamentals of the universal language.

Looking to learn the basics of electricity in a fun way? Manga Guide to Electricity by Kazuhiro Fujitaki. Now in stock in the Adafruit store and shipping immediately!

Rereko is just your average high-school girl from Electopia, the land of electricity, but she’s totally failed her final electricity exam! Now she has to go to summer school on Earth. And this time, she has to pass. Luckily, her ever-patient tutor Hikaru is there to help. Join them in the pages of The Manga Guide to Electricity as Rereko examines everyday electrical devices like flashlights, heaters, and circuit breakers, and learns the meaning of abstract concepts like voltage, potential, current, resistance, conductivity, and electrostatic force.

The real-world examples that you’ll find in The Manga Guide to Electricity will teach you:

• What electricity is, how it works, how it’s created, and how it can be used
• The relationship between voltage, current, and resistance (Ohm’s law)
• Key electrical concepts like inductance and capacitance
• How complicated components like transformers, semiconductors, diodes, and transistors work
• How electricity produces heat and the relationship between current and magnetic fields

If thinking about how electricity works really fries your brain, let The Manga Guide to Electricity teach you all things electrical in a shockingly fun way.

Kazuhiro Fujitaki is a lecturer at the Tokyo Metropolitan Vocational Skills Development Center. He has written a number of books on electrical engineering and runs a website offering useful information about Japan’s qualifying examinations for electrical technicians.
