A lot to learn from this video about explaining things:
- Know your stuff. It's obvious he's been over all of this hundreds of times.
- Figure out great analogies and other aids. Part 3: 5:20 he makes an analogy out of multiplying bacteria in a bottle that fill it in an hour to show us at what point of the exponential function you notice your in one. It's got two parts and is very effective. It allows him to say things like "5 minutes before the bottle is full."
- Introduce your aids gradually and keep using them. Make clever decisions about your aids and make sure they accumulate to a powerful toolset. After that analogy which all the time he introduces the analogy above he has:
- A trick for calculating doubling time 70/annual growth in %
- A graph
- A table
- An example (Boulder) that he keeps running scenarios on.
- The bacteria analogy
By the time he's 20-30 minutes into a lecture, this guy has a very powerful vocabulary built up. He can take something like oil consumption and examine it with you very quickly using these tools. The bacteria in a bottle analogy is a great example of this. Once he's explained it (kind of hard) and practised it once or twice, he can say "What time is it?" and immediately have his audience understand something relatively complex. .
