On the relationship between media, representation, communication and thinking, this part remembers me of Bret's Victor Media for Thinking the Unthinkable

In some talk, I don't remember if this one, Victor says that using printing media as the main medium for communication is kind of an historical accident. It could be sound, or other media as main representation/communication vehicle.
On my own memories, I remember thinking the relationship between representation and processing/cognition in my early undergrad years as a freshmen, when I saw the two notations for derivates (Leibnitz's and Newton's) and how both make some kind of operations easier (or not). The example I came with, to explain such insight to my postgrad education sciences students later, without appealing to calculus was multiplying in roman numbers versus in arabic ones (and example I would find years later is also employed by Victor)
