A time series is a sequence of observations or measurements ordered in time. The first picture that comes to mind when talking about time series is usually stock prices. However, time series are ubiquitous.

Blog posts can be strange and unpredictable things. There are times when I pour a ton of energy and creativity into a post only to have it largely ignored. Other times I quickly and haphazardly put something together and it ends up attracting thousands of hits. Such was the case with my recent post, Must-know terms for today's intelligentsia. Owing to all the interest, feedback and requests, I've decided to revise the list and provide greater detail and links. I apologize for not providing this in the first place. Before I get into the list, however, I'd like to clarify the purpose of this exercise. First, I am trying to come up with a list of the most fundamental and crucial terms that are coming to define and will soon re-define the human condition, and that subsequently should be known by anyone who thinks of themselves as an intellectual. I admit that there's an elitist and even pompous aspect to this exercise, but the fact of the matter is that the zeitgeist is quickly changing. It's not enough anymore to be able to quote Dostoevsky, Freud and Darwin. This said, while my list of terms is'required' knowledge, I am not suggesting that it is sufficient. My definition of an'intellectual' also requires explanation. To me an intellectual in this context is an expert generalist -- a polymath or jack-of-all-trades who sees and understands the Big Picture both past, present and future.

We live in an era of accelerating change, when scientific and technological advancements are arriving rapidly. As a result, we are developing a new language to describe our civilisation as it evolves. Here are 20 terms and concepts that you'll need to navigate our future. Back in 2007 I put together a list of terms every self-respecting futurist should be familiar with. I reached out to several futurists, asking them which terms or phrases have emerged or gained relevance since that time.

These forward-looking thinkers provided me with some fascinating and provocative suggestions -- some familiar to me, others completely new, and some a refinement of earlier conceptions.
