“Actually, Quaternions failed because they perverted what the Vectorists thought they know of God’s intention — that space be simple, three-dimensional, and real, and if there must be a fourth term, an imaginary, that it be assigned to Time. But Quaternions came in and turned that all end for end, defining the axes of space as imaginary and leaving Time to be the real term…” — Thomas Pynchon, Against the Day
Time as the real and everything else as imaginary.
Think about the implications for a moment.
If Time is all that is truly real, why do we waste so much of it seeking the the imaginary?
