First 10,000 digits of Pi in blue and orange Spiral Notebook
This wonderfully geeky design is the perfect gift idea for an engineering student, or any math geek in general. It features Pi, the famous mathematical symbol and number. This number is closely related to the circle, which also makes its appearance in the design, very lightly shaded over the digits. Pi is derived from the division of a circle's circumference and its diameter, and this simple division yields this powerful number. No repeating pattern has been found to describe Pi, and it is considered an irrational number. Showcase your geeky, math-loving side with a lot of style with this design.
