    I attended class today and I appreciated the joke.

    I liked the talk on how we identify if something is actually ours.

      Thanks for that, Erik. As a quick illustration, imagine you’ve rented a car from Budget. In the parking lot outside your hotel, a thief is breaking in to the car you recognize as the one you rented. You say: “Hey, that car belongs to Budget, and I will report to them that you are leaving here with their property!” Or you say: “Hey, that’s my car!”

    The feedback today was interesting to see because I enjoy hearing other peoples views about the class.

    I was mystified with the coffee filter in the water. The only reason that might be possible was that the pressure of the air was stronger than the pressure of the water around the filter. I am going to try and figure it out when I get back to my room.

    • davidbdale's avatar davidbdale says:

      I guess pressure is a reasonable candidate, Erik, but I’ve been thinking maybe cohesion is the better answer. After all, air does stay clustered together in bubbles when it makes its way to the surface of water, right? So maybe the natural tendency of air molecules to stay together is stronger than the force that would make it rise?

    I was here last class but forgot to comment on this post but I liked the talk we had about your shopping list and how that was an argument. It surprised me once you explained it because i never thought that a simple shopping list could be an argument

    The Lasik surgery talk we had gave me some good ideas about how I can help make an argument and proposal for my topic of choice. I taught me what I have to consider when writing about a topic and being persuasive.

    I forgot to post last class but the videos and information about the table saws really caught my attention. It amazes me that people can create saws that will stop in a couple of milliseconds when touched by the human hand.

    The video of why we should have people on death row donate organs to help other people was very interesting. It makes sense to me because the people on death row killed people and in turn should save people by donating their organs. Its a complete waste to just kill these criminals without taking into consideration the people who could benefit from what they offer.

    The question of what is sex and what is gender was interesting because I never thought of it they way you described it. The Heightened Security essay we reviews in class is going to help me extremely when I start writing mine.

    The riddle in class got me thinking but I still did not understand your argument for how many options there were for the dogs. No matter how much I thought of it I could only still logically think of two options.

      Thanks for saying so, Erik. Allow me to offer two charts that show the situations the best I can understand and explain them. For the Monty Hall problem, in which the contestant first chooses a door, then gets shown a goat behind another door, then has to decide whether to switch her choice or stick with the original door, there are exactly six possible scenarios, three in which she sticks, and three in which she switches. The patterns look like this:
      SHE STICKS WITH HER ORIGINAL DOOR
      CAR GOAT GOAT She sticks with 1 and wins.
      GOAT CAR GOAT She sticks with 1 and loses.
      GOAT GOAT CAR She sticks with 1 and loses.
      Odds of winning by sticking: 1 in 3

      SHE SWITCHES DOORS AFTER BEING SHOWN A GOAT
      CAR GOAT GOAT She abandons Door 1 and loses.
      GOAT CAR GOAT She abandons Door 1 and wins.
      GOAT GOAT CAR She abandons Door 1 and wins.
      Odds of winning by switching doors: 2 in 3.

      Now, for the beagles, there are four original possibilities.
      BOY BOY
      BOY GIRL
      GIRL GIRL
      GIRL BOY
      All four possibilities are in play before we know one of the dogs is a boy. So the odds of either dog being male are 4 in 8, or 1 in 2.

      But as soon as we know “at least one” of the dogs is a boy, we’re down to three possibilities:
      BOY BOY One is a boy; the “other dog” is a boy
      BOY GIRL One is a boy; the “other dog” is a girl
      GIRL BOY One is a boy; the “other dog” is a girl
      Odds of the “other dog” being a boy? 1 in 3.

      Does that do it for you?

    It definitely makes more sense now. Thank you for taking the time to respond.

    There is no final for this class

  13. erikobs's avatar erikobs says:

    I thought I understood what the cause and effect was for my essay but the more I try to write about it, the more trouble I have figuring out what to write

  14. erikobs's avatar erikobs says:

    I appreciate the feedback we got on our titles today in class.

  15. erikobs's avatar erikobs says:

    The essay we read today in class will definitely help me when writing my first draft.

    The analyzation of the video was impressive. I didn’t realize that we could talk for 10 minutes about each second of the video.
