okay, same thing is true in our workplaces. now, most of us work in open plan offices, without walls, where we are subject to the constant noise and gaze of our coworkers. and when it comes to leadership, introverts are routinely passed over for leadership positions, even though introverts tend to be very careful, much less likely to take outsize risks -- which is something we might all favor nowadays. and interesting research by adam grant at the wharton school has found that introverted leaders often deliver better outcomes than extroverts do, because when they are managing proactive employees, they're much more likely to let those employees run with their ideas, whereas an extrovert can, quite unwittingly, get so excited about things that they're putting their own stamp on things, and other people's ideas might not as easily then bubble up to the surface.
now i think at this point it's important for me to say that i actually love extroverts. i always like to say some of my best friends are extroverts, including my beloved husband. and we all fall at different points, of course, along the introvert/extrovert spectrum. even carl jung, the psychologist who first popularized these terms, said that there's no such thing as a pure introvert or a pure extrovert. he said that such a man would be in a lunatic asylum, if he existed at all. and some people fall smack in the middle of the introvert/extrovert spectrum, and we call these people ambiverts. and i often think that they have the best of all worlds. but many of us do recognize ourselves as one type or the other.

i have the answer to a question that we've all asked. the question is, why is it that the letter x represents the unknown? now i know we learned that in math class, but now it's everywhere in the culture -- the x prize, the x-files, project x, tedx. where'd that come from?
about six years ago i decided that i would learn arabic, which turns out to be a supremely logical language. to write a word or a phrase or a sentence in arabic is like crafting an equation, because every part is extremely precise and carries a lot of information. that's one of the reasons so much of what we've come to think of as western science and mathematics and engineering was really worked out in the first few centuries of the common era by the persians and the arabs and the turks.
this includes the little system in arabic called al-jebra. and al-jebr roughly translates to “the system for reconciling disparate parts.“ al-jebr finally came into english as algebra. one example among many.
the arabic texts containing this mathematical wisdom finally made their way to europe -- which is to say spain -- in the 11th and 12th centuries. and when they arrived there was tremendous interest in translating this wisdom into a european language.
