Geometry that anyone with half a brain can understand

if a = b and b = c, then a = c

Is this some sort of new math?

A high school geometry teacher has been placed on paid leave and may be fired after using the example of shooting President Obama in a geometry lesson.

A student in the class described the lesson: “He was talking about angles and said, ‘If you’re in this building, you would need to take this angle to shoot the president.'” (Source.)

Think about the possibilities this opens up to finally, at long last, make word problems more interesting.

“Assume that little Johnny’s brain weighs 3 pounds. A pipe bomb is used to blow his head off, destroying 20% of brain mass. Then a chain saw is used to cut what remains exactly in half. How much brain matter remains?”

Yeah, much more interesting. Perhaps I should drop my plans to write a novel and go into mathematics textbooks instead. This might be the sign I’ve been looking for. This just might be my big break!

  1. Lucky they didn’t try it out in theory! Hmm, so what was the answer, a curious Loon wants to know!


    1. 1.2 pounds. πŸ™‚


  2. I think that may be just a teeeeeny bit scaring on young impressionable minds… But hey, they’ve gotta learn about the cruel world we live in sometime, right?


    1. I really think this opens up a whole new world of possibilities for math.

      Two trains are traveling towards each other. They start 100 miles apart. Train A travels at 40 mph and has a bomb with a 12-minute timer and 57 people on board. Train B travels 55 mph and has a bomb with a 10-minute timer and 93 people on board.

      1. Which train travels the farthest before it blows up?
      2. Once both bombs have blown up what is the remaining distance between the trains?
      3. How many people on each train survive the explosions?


  3. Something tells me if this was under Bush, this wouldnt have been posted.


    1. You don’t know me well enough to know the answer to that question, but don’t let that stop you from calling me a hypocrite. I guarantee you I’d find the story offensive under any president.


  4. Frightening.
    My physical science teacher high school hated cats and his equations on velocity and momentum would always involve a cat being thrown out a window or propelled via cannon or some such torture. Charming.


    1. Wow. So this phenomenon isn’t exactly new. I was lucky in high school. My physics teacher rocked.


    2. Anyone who hates cats should be tossed from the Leaning Tower of Pisa with an equal weight in iron, preferably right on top of him. Actually, I’m not a violent person…so I take that back! (Ugh, the photo of the snake eating the frog. Nightmares!)

      I always thought that mathematics classes would be a whole lot more enjoyable if you used real world problems that were useful in some way. I wasn’t thinking of bullets, but of figuring out the square footage of fabric to cover a sofa and such. Yikes, that geometry problem was so inappropriate, so wrong. There seems to be a tradition of hating on the presidents. There was a movie called “Assassinating Bush.” Hopefully, it wasn’t shown to school children.


      1. I couldn’t agree more about the cat thing. Any sort of animal, actually. I hate the abuse of power.

        The photo for this post was actually a compromise. I had scanned a lot of photos searching keywords like vivisection, autopsy, and dissection. In the end I went for something slightly less provocative. πŸ™‚

        The thing that bothers me is that I wasn’t happy about the “election” of George Bush. But I never comported myself in way that seems to be mainstream with the anti-Obama haters. I’d say, for example, “I don’t agree with the President on Iraq.” These days that sort of opposition would be considered prudish. Political divisiveness has gone too far in my opinion.


  5. For those of you who are critical thinkers and read the story, you’ll note the teacher is not named. As far as I can tell his/her identity is being protected.

    Here are a few more details that I was able to get:

    1. The parent of a high school student originally alerted the school board.
    2. The school board alerted the Secret Service.
    3. The Secret Service contacted the teacher and found “no credible threat.”
    4. The teacher works at Corner High School in Warrior, Alabama. This is a public school.
    5. The teacher is a member of the AEA (Alabama Education Association) union.
    6. The teacher and his union representative met with the Superintendent and was apologetic.
    7. attempted to contact the teacher through the AEA union and was unsuccessful.


  6. This post (text and image combined) reminded me of two very important things: Why I stopped attending school pretty much after the 7th grade, and the meat grinder animation from Pink Floyd’s Another Brick in the Wall – part 2 😐


    1. Did you happen to know I like that movie? πŸ™‚


      1. Weird minds think alike? πŸ™„


Bringeth forth thy pith and vinegar
