SCIENCE!!! Here are some buttons for all you science lovers. I was a bio major in college and I’m still a big science geek. ;) I tried to get creative with the hearts, it was difficult but fun.
The biology button has a strand of DNA for the “I” a diagram of blood flow in the heart, and paramecium spelling out “biology”.
The chemistry one is pretty self explanatory, I used the chemical symbols to spell “love” (well, luv anyway).
The formula under the graph on the math button actually will make that heart shape on graph. I got the formula from here: http://mathworld.wolfram.com/HeartCurve.html
The physics button has the equation equation for the gravitational force between two objects (attraction, get it?)
The biochemistry button has an oxytocin molecule, the “love hormone”.
For the astronomy one I drew the heart nebula, which is a real nebula located in the Perseus Arm of the Galaxy in the constellation Cassiopeia. Space stuff is really hard to draw. D:
Send me a note if you’d like to buy one. :)
