Jim Al-Khalili - The Story of Information

01:30 Review of Al-Khalili’s vid on the Slit Experiment
05:25 Summary: The Rope Hypothesis explains the Slit Experiment
07:08 Review of fatal problems with Mathematical ‘physics’
12:00 Introduction to Al-Khalili’s talk on information: order, enables the mathematicians to understand the workings of the Universe. Is that so?
15:30 Harness a concept? How do you do that, Jim?
16:35 Al-Khalili: “We are surrounded by order!”
18:25 Al-Khalili is a caricature of Science: information exists, attempts to grab concepts. 24:30 Al-Khalili is definitely a caricature of Science: he moves concepts around.
29:45 Al-Khalili morphs info into a rock.
30:10 History of information.
35:00 Shaka Zulu’s version of information.
36:10 Sumerians invented writing.
36:40 Other cultures invented writing independently. Therefore, writing was ‘in the cards’.
38:20 History of human modes of production was also ‘in the cards’ and leads to extinction of Man. Information is, therefore, not eternal.
40:45 Al-Khalili takes information outside the body.
44:00 Until the 19th C, info could travel only as fast as objects. 44:50 Development of the telegraph sped things up.
47:35 Maxwell’s demon shows we can convert information into order without expending energy.
50:35 What is Maxwell’s demon?
51:15 Al-Khalili’s corollary: Demon uses nothing but info to create energy.
53:20 Two components to info: data and what to do with it. Binary system.
55:55 Al-Khalili: information is a concept. Computers DESCRIBE complexity with luxury of details. Computers can’t EXPLAIN mechanisms.
58:55 Al-Khalili: information is NOT a concept. Info can be stored and carried.
01:01:00 If you can store info, it implies that you can also handle it. Is DNA information or just a molecule?
01:04:35 Summary
01:07:25 Corollary: What is information?
