Through my work as a data scientist, I frequently encounter all manner of dubious forecasting models, most of which, nevertheless, rely upon exceptionally sophisticated mathematics. How many of these so-called scientific models, I wondered, could even beat the predictions of superstitious astrology? It’s a question I became very curious to answer. But what, actually, is astrology?
In my new book, A Scheme of Heaven: Astrology and the Birth of Science, I set out to recast astrology as the ancient world’s most ambitious applied mathematics problem, a grand data-analysis enterprise sustained for centuries by some of history’s most brilliant minds from Ptolemy to al-Kindi to Kepler.
Just consider that for much of the last two thousand years, the word “mathematician” (mathematicus) simply meant an astrologer – there was no distinction....
Astrologers were the quants and data scientists of their day, and those of us who are enthusiastic about the promise of numerical data to unlock the secrets of ourselves and our world would do well simply to acknowledge that others have come this way before.
Whether you’re intrigued by astrology, repelled by it, or anywhere in between, I contend that astrology remains tremendously relevant as a challenge to what we think we know and why we think we know it. Regardless of whether astrology has distilled any truth or not, what seems clear to me is that it has bottled up a certain type of magic, one that has proven time and again its ability to get us to stop and think about our connections to the wider universe.
