Alan Kay: cool concepts also need love

Let me start by showing a video recorded by the National Science Foundation (NSF) at the recent graduation ceremony at Harvard, where they asked some alumni and their teachers to answer some simple questions about what caused the change of time year and phases of the moon. Everyone was sure of their answers, but about 95% of the respondents did not even closely approximate the scientific justification.
 
 
Their main theories were based on the fact that the change of seasons is a consequence of the decrease in the distance between the Earth and the Sun in the summer, and that the phases of the ...

Alan Kay: How things are for all mankind, the view "from outer space"

Alan Kay: How things are for all mankind, the view "from outer space" Why then is science and its cartographic language - mathematics - considered difficult to study? I believe that this is not because they are so complex, but rather because they are surprisingly simple, but very different from ordinary, sound human thinking.
 
My favorite examples of early science and a wonderful overall metaphor about what science is doing are attempts at accurate mapping, which was initiated by the Greeks and lost afterwards for thousands of years, and then resumed in the 15th century. By the end of the 1700s, people were delighted that they could buy a pocket globe of "the ...
