I enjoy watching Jeopardy!, even though I don't need dentures or “diabeetus” testing supplies. Part of the appeal for me is that I get to pick up little tidbits of information that I didn't know before. As a software developer, I find that I have pretty deep knowledge in my field, as one would expect, but that the waters become far too shallow or dry up completely in places when one moves too far away from the software area. Sure, this is the age of specialization, but I would like to be more well-versed in other areas.
Jeopardy! is pretty darn good at revealing what areas need the most work. If the category relates to technology, physics, math, English or Spanish, I'll probably do well. If it's history, art, literature, politics, sports or popular culture (not to mention the ever-popular “Potent Potables”), the odds are good that I'll strike out, or at least do poorly. Geography, chemistry and biology tend to end up somewhere in the middle. Even in the areas where I tend to do well, I will too often experience the distressing sensation that I used to know this in high school.
So I'm looking for ways to obtain more well-rounded knowledge. Watching Jeopardy! is one way, I suppose, but the problem with Jeopardy! is that what I pick up there doesn't tend to “stick” very well. An ideal solution would cover a wide range of subjects, encourage retention of the new information, not require a large investment of time each day, and be inexpensive or free. Any ideas?
