What Is Your Petri Dish?

2013.01.16 What's Your Petri Dish
A petri dish is a small container used by scientists, usually biologists, to discover and explore cultured cells, plants, and so on.┬áIt’s usually, but not always, 100mm in diameter and 15mm in height. In 1887, it played a key role in discovering penicillin. While petri dishes come in different sizes and other variables scientists do great work with them. They’re only so big; they’re only so small. It’s a 100mm x 15mm constraint where the world is changed. A petri dish is a tangible disc of embracing constraints: there are parameters and boundaries… yet so many wonderful things can happen within those boundaries. A petri dish is a playground for the creativity of a scientist.
A standard “letter” size piece of paper is 8.5″ x 11″ in diameter. A hard drive holds a certain amount of documents. A canvas or piece of fabric can be any size in theory yet at some point it has to be cut.
Stages come in a variety of sizes, yet each is a size. Speeches and sermons can only go so long before they become rants. Soapboxes are only so high, so wide, so placed, so sturdy, and so afforded.
A guitar has only six strings. A ukulele has four. An erhu has two.
