I’ve been too busy to blog

by Janie Jones

I’ve been swamped with homework.  I’m writing two papers this year, and one of them has a big first draft phase due today.  Also due today is my group physics project.  We built a catapult:

Life in a physics cartoon

I went to get help from my physics TA.  This is the result of 45 minutes of “help” with a homework problem.

No Freakin’ Way. Did that really just happen? To me?

by Janie Jones

So you must now all share in my Physics shock.

Today we had lab.  Lab so far has been mostly us looking confused and in pain trying to follow the mumbling ramblings of our teaching assistant (the TA) who is apparently too brilliant to be understood by any of the classmates I’ve talked to about what is going on in lab.

Today’s lab was on projectile motion.  I had been assigned a lab partner whose grasp of physics was no better than my own.  Somehow, perhaps due to the grey hair, I became the “leader,” and was responsible for most of the measurements and calculations and I pretty much thought we’d be screwed.  We had to calculate where to put a small cup on a stand on the floor in order to catch a ball which was released from a ramp which shot it off the table.  We were given the height of the opening of the basket and the diameter of the opening (which we were told wasn’t strictly necessary for the calculations).  We had to measure all the rest of our variables, calculate the speed and velocity of the ball, do the derivations for the equation to calculate the position for the basket, and then, once we had done the calculations we were given 5 tries to try and get the ball into the basket.

If the ball went in on the first try we’d automatically get full credit for the lab without having to do the homework for the week.

If the ball went in on the second try, we’d still have to do the homework and we’d only earn the points we earned from doing the homework.

If the ball took 3 tries, we’d have to do the homework, but with a 1 point penalty to our final homework grade.

If the ball took 4 tries, we’d have to do the homework with a 2 point penalty.

And if the ball took 5 or more tries, we’d have to do the homework with a 3 point penalty.

I was hoping against hope to break even and just not have to worry about a penalty, because I figured there was no way my partner and I would be able to sink that ball on the first try.  After all, I was the one leading this party and it involved math, my arch nemesis.

So, we measured the speed of the ball and I calculated the velocity of the ball.  I measured the height of the end of the ramp.  I asked for just a little help with deriving the equation to make sure I was going in the right direction.  I crunched the numbers.  I conferred with my partner, who said, “I trust your math more than mine.”  I shuddered, that did not bode well.

From there I followed the directions implicitly.  We used a plumb bob to find the horizontal position exactly below the ramp.  We shot the ball off the ramp onto carbon paper so it marked the floor where it hit, then we shot the ball from about a third of the way down the ramp onto the carbon paper to mark a second point.  I got out a meter stick and lined up the two carbon paper points and the point indicated by the plumb bomb exactly below the ramp.  Then I placed a target at the distance from the ramp that I got from my calculations, lining up the cross hairs with the line connecting my three points.  I verified this with my partner.  We agreed this was as good as it was going to get.  We agreed that it would take a miracle for this to work.  I said, as long as it goes in on the second try I’ll be tickled pink.

The TA brought over the cup on the stand and lined it up on our target.  My partner released the ball down the ramp.  I stood at the basket waiting to judge how far it was off so I’d be ready to adjust it accordingly.

And, then the damn thing sunk perfectly in the cup on the first damn try.

Damn.

I’m stunned.

And thrilled I don’t have to do lab homework this week.

Happy Elephant Appreciation Day

I didn’t believe it, but apparently it’s true. Today is National Elephant Appreciation Day.

Why shouldn’t they get their own day?  They are pretty magnificent.  Who doesn’t like elephants, or at least respect them?

As Graydon Carter, an American journalist, says, “We admire elephants in part because they demonstrate what we consider the finest human traits: empathy, self-awareness, and social intelligence.

Of course we, as humans, have an odd way of showing our respect sometimes, the rest of that quote goes on, “But the way we treat them puts on display the very worst of human behavior.

I guess they have been considered endangered/vulnerable species, but without doing some digging I don’t know where they stand today.  I seem to recall once hearing that a zoo would give their elephants painting supplies and sell their artwork to generate funds.  Apparently elephants are considered to be extremely intelligent and have a sophisticated elephant culture.

But when it comes to quotes, I think Dr. Seuss says it best, “I meant what I said and I said what I meant – An elephant’s faithful, one hundred percent!

Here are some fun facts about Elephants, in no particular order:

  • Elephants don’t really like peanuts.
  • Asian elephants don’t actually run, which would require having all four feet off the ground at once.  Asian elephants always have at least two feet in contact with the ground.
  • Elephants will recognize themselves in a mirror.
  • Elephants can get sunburned.
  • Elephants have 6 toes.

These and other fun facts were found at Smithsonian.com website.

And even though it’s not Tuesday, here’s a joke in honor of National Elephant Appreciation Day:

Q: What do you get if you cross an elephant with a whale?
A: A submarine with a built-in snorkel.

This and other elephant jokes can be found at Elephant Jokes-Lanet.

 

Have a great day, and don’t forget National Elephant Appreciation Day!
