Its a cool idea, but I am slightly dubious that you can learn an interesting amount of knowledge about any of those topics in an hour...

True, it would be very difficult to gain a meaningful amount of knowledge in that time. But I view it as a gateway into subjects that I normally wouldn't touch. It is more about exposure rather than depth.

Another purpose of the project is to get out there and have meaningful interactions with others. It's fantastic to be taught by someone who is passionate about what they are teaching.

Brilliant idea!

We covered quite a bit of ground in our couple hours and now I want to continue this project on my own. Cheers.
