Science Combo Pack Stationery (4)

Description

Perfect for your four best friends - the chemist, the biologist, the physicist, and the mathematician. Four (4) blank ivory greeting cards with envelopes. I screen printed one of each design onto the front of each card. They are original and handmade designs by me! Signed on the back in small letters.

You will get one of each design. ~4x5.5"

A bit about the designs:

The Chemist
Avogardro’s Number is one of the most important constants in Chemistry. What is it? Well, a mole of any substance consists of Avogadro's number of the constituent entities of that substance. That should clear things up.

The Mathematician From wikipedia...
"Pi or π is one of the most important mathematical constants, approximately equal to 3.14159. It represents the ratio of any circle's circumference to its diameter in Euclidean geometry, which is the same as the ratio of a circle's area to the square of its radius. Many formulae from mathematics, science, and engineering involve π."

The Physicist
This formula was derived by Albert Einstein and is the mass-energy relationship for special relativity.

The Biologist
Diatoms are typically unicellular organisms that can be found in fresh or sea water or moist areas. They are believed to have originated during or before the Jurassic period. They are an important food source of mollusks and fish. My father is a biologist and has spent a lot of time studying these organisms, and this design is dedicated to him. These diatoms are my own renderings of a Pinnularia, and some other species inspired by these photographs: http://thalassa.gso.uri.edu/flora/arranged.htm

Shipping:
First Class USPS for domestic orders. If you buy multiple items, each additional item is only 20 cents extra. For international orders, I will ship it with International First Class USPS. It says that the time "varies" for this method of shipping and I agree -- it REALLY varies!
