watched the 2 minutes of the video. He seems like a great professor. Later this year I'm definitely going to sit and listen to each of his lectures on this topic.

Sorry...isn't this lecture supposed to be a bit longer? I believe Professor Goldwhite was in the middle of a sentence when the video abruptly ended.

It keeps re buffering and going back to the very beginning. "Welcome to Educator", kind of frustrating.

I make a stew which uses kidney beans. I soak the beans overnight in water, and by morning, they have "swollen". I've been making this for 20+ years. The last few times, the beans have not absorbed the water. Do you have any idea why this might be?
