Robert Sabbagh on 01 Dec 13After watching this video, the first thing that came to my mind was, "wooooow". I really liked the way Mr. David Christian had explained his thoughts and ideas. His analogy of the egg being mush and our complexity being similar was clear in his context. It all also made sense to me about the difference between humans and other species since we have language and a different degree of collective learning. Overall, the video was very instructive, explanatory and very well constructed. That's why even though it seemed to be very confusing and had a sort of overload of information, the way it was represented made it easier for the audience to comprehend. That's why I got the chance to really understand and think about his ideas in depth. The way he studied history and explained it to the audience was most entertaining and educational in my opinion. The reason I think this is because he took a different approach to history. Usually when people refer to history it's focused on human history and what we had done as species. But his approach is very scientifically based and focused which made it more factual which in affect made it make more sense to me. I understood what he meant about the complexity of the world being the base of it's development although I didn't completely understand it.

Himesh Settinayake on 03 Dec 13The most intriguing idea I took from this video was the first concept presented by David Christian - the idea that the general tendency in the universe is for things to go from order to lack of order and entropy. Although he does present this idea in the context of physics through the second law of thermodynamics, I find this a little confusing personally because if I were to think in terms of, say, particle physics, the general tendency is for particles to decay from a high energy state to a low energy state; this could be interpreted as things going from lack of order, to order, contrary to what Christian introduces in his TED talk (do correct me if I'm wrong). However, I do see the error in my thought processing as I realise that if I were to look at things in the context of scientific history, single-cell organisms evolved into multiple-cell organisms, which then developed tissues and organs and so on and so forth. From this perspective, I completely understand the tendency of "mush" going to complexity. Hence, I am a little perplexed at this first premise of the video. I found the Goldilocks condition to be intriguing as well as we see this happen often if we were to look at it in terms of science. For instance, an electronic transition can only occur if you transfer the exact amount of energy to an electron, or the activation energy required for a chemical reaction to occur (you may have noticed my trend to look at things in terms of science). If the model of the universe follows these Goldilocks condition, would it ever be possible to predict the next "threshold" of development? This comes back to the Positivist school of history: the idea that we are able to predict future events based on patterns derived from the past course of history. However, as we established today in class, history may not exactly be predictable, due to inconsistencies and irrationalities of the human mind. Then again, factoring out mankind and its tendency to be illogical
