So, things that I don't understand and it bugs me:
-Dimensions 5 and above
-Dark Matter (I can't say I fully understand string theory, but if you want a better understanding you absolutely have to read "The Elegant Universe" by Brian Greene)
-Saying we can't expand social services now because it will cost too much, then having to pay much more about 10 years down the road for all the people who slip through the cracks because we couldn't care for them now (why not just suck it up now and save a ton more money later on?)
-Larry the Cable Guy (and why he is successful)
-Why people think Kobe is a top 15 player of all time
-Why people can't understand that teammates matter a lot to a team's success in basketball (a la the Duncan vs KG debates or the unstoppable kobe hype machine)
-Why my shots rim out and everyone else's rim in
-Why everything good for you tastes bad and everything bad for you tastes so darn good
-Tyranosaurus Rex (I mean really stop and think about what it would be like to encounter a 40 foot tall land dwelling reptilian carnivore? I mean how much muscle mass is there? It's ridiculous.)
-Today's computers (microprocessors, hard drives, how info is stored, how one actually makes a hard drive or a microprocessor...geez.)
-My cat's moods.
