    1. Gray discusses the ‘bandwidth of consciousness’. He cites figures from Vincent Deary who has calculated that overall we process some 14 million bits of information per second. But the bandwidth of conscious action and thought, however, is only 18 bits!
    1. I am increasingly concerned when I hear my colleagues refer to themselves with computer metaphors—“I don’t have the bandwidth,” “I have to boot up,” or “I need to recharge.”
    1. Now, if we think of the tasks that we perform throughout the day as consuming separate "bands" of time, then the term makes perfect sense.

Using the term bandwidth to describe time maps more closely (in my opinion) to the original definition, than the current definition describing data capacity does.
    2. Bandwidth, literally, is the amount of data that can be passed along a communications channel in a given period of time.

    1. There must be an ‘industrial revolution’ in education

      This first phrase is the most telling of all the issues we deal with on the edtech front. Because the industrial revolution touched almost every aspect of life since its inception, everyone presumes that it must also affect education.

      Sadly other than helping to make searching for and obtaining material much quicker, it still needs to be consumed, thought about, and digested by a student. The industrial revolution simply hasn't increased the bandwith of the common student's brain. It's unlikely that anything in the near future will expand it.
