Pi is magic. It is a number that is infinite, universal, transcendental, and irrational. It appears everywhere, and my mathematician friends tell me that Pi is as close to religion as you can get in math. Pi is a perplexing, elegant representation of something vast and profound. The symbol 蟺 was first used by William Jones, a Welsh mathematician, in 1706 as an abbreviation for the ratio of the circumference to the diameter of any circle, yet that description belies the power and range of Pi.
Pi can be fun. Some people enjoy playing games with Pi and challenge themselves by seeing how many digits they can memorize. Here is Pi to the 50th decimal point: 3.14159265358979323846264338 32795028841971693993751. Now, with the help of computers Pi has been calculated to 62.8 trillion decimal places. One of the allures of Pi is that we can鈥檛 totally know it and it goes on for infinity with no repetition or pattern. If there is a pattern, no one has discovered it yet.
I think it鈥檚 always more interesting when you cannot totally grasp or know a thing, there is a sense of mystery and unattainability. I am a visual artist鈥攏ot a mathematician鈥攂ut I have spent much of the last several years photographing the chalkboards of some of the greatest mathematicians in the world. I was interested in recognizing, celebrating, and seeing the beauty of higher mathematics. And I was lucky to be invited into the insular and mysterious world of mathematics through my friendship with the mathematicians Amie Wilkinson and Benson Farb, a married couple who both teach at the University of Chicago.
Amie and Benson are 鈥渢heoretical鈥� or 鈥減ure鈥� mathematicians, which means they do 鈥渕ath for math鈥檚 sake.鈥� They are interested in ideas, abstraction, exploring the boundaries of pure reason without explicit or immediate application in the physical world鈥攁kin to art, philosophy, poetry, and music. Practitioners of applied math, on the other hand, use theories and techniques to solve 鈥減ractical鈥� problems in the physical world. Although their objectives are different, these two branches of mathematics are inextricably linked: there are numerous examples of discoveries in pure math that were abstract at the time but would be revealed to have revolutionary applications years later. In fact, one could say that all modern technology is derived from pure mathematics.
Photographing the mathematical formulas on chalkboards was an interesting way for me to get a window into their world. As an outsider, the formulas and mathematical symbols were inaccessible to me. And I didn鈥檛 mind not knowing. I actually liked the tension of being seduced by the formal abstract beauty鈥攖he patterns, symmetry and structure鈥攚hile simultaneously feeling totally disconnected, not being able to fully access the meaning of their work. This friction of being drawn in and pushed away was exciting to me. I may not know the specific meaning of the theorems, but I do know that beyond the surface they are ultimately revealing (or attempting to reveal) a universal truth.
The work of these mathematicians should be recognized and understood as important contributions to furthering knowledge and helping us understand the world around us. In fact, numbers and mathematics are in the fabric of our universe, and some mathematical Platonists believe that mathematics exists independently of the human mind, just as planets and stars exist. We should have more days in the year that celebrate numbers, mathematics, formulas, and mathematicians. But for now, on 3-14, let us pay tribute to and celebrate Pi, a ubiquitous, unique number that continues to fascinate us all.
