99 bottles of…oops January 28, 2014

Yesterday, I was helping guide some cub scouts (specifically webelos) through their scientist achievement.  One of the things we had to discuss was Pascal’s law.  Unfortunately, the instruction set on this was pretty limited: read and discuss.  That, to me, means they likely wouldn’t understand it at all, so I felt like a demo was in order.

I decided to demonstrate the pressure change in a beer bottle.  The concept is simple: fill an empty bottle with a non-compressible fluid (so water works, air won’t) and tap on the open end with a rubber mallet or even your hand.  Of course, you want to do this over a bucket because the sudden change in pressure causes the bottle to break at the weakest point, usually the seam along the bottom, and spill it’s contents.

I did this demo for the first time in front of the kids.  (I had ONE bottle of beer.  No, I didn’t imbibe in front of them…I used it to bake bread.)  It worked like a charm.  If I didn’t trust physics so much, I wouldn’t have been okay trying it cold like that.

If you don’t have a beer bottle handy and would like to see this demo, there’s a good video on YouTube:

This is NOT what a scientist looks like August 26, 2013

The younger son’s school is starting a new science curriculum this year. Mike and I were very excited to learn about it as it’s supposed to emphasize hands-on learning. But this came home today, and I could only roll my eyes. Can you see what’s wrong?

I only wear goggles when swimming May 21, 2013

I was recently chatting with an acquaintance when they mentioned they had seen me in the local paper a while back.

You were wearing goggles, right?

No.

Well, you did have a lab coat…

No, I was actually wearing a sweater.

I have had articles on my work run in the paper a couple times in the past few months. However, only one had a picture, and I cringe every time I think about it. I learned the hard way that it is important to wear solid colors on such occasions.

The picture involved me standing in front of several racks of computers wearing a rather ugly ombré sweater. I find it interesting that this acquaintance knows I’m a scientist and equates that with the goggles and lab coat schtick so heavily that they remember me wearing one even when I was not.

I remember reading about a project where kids drew pictures of scientists, visited some at Fermilab, and then drew pictures after their visit. The contrast was striking.

Having talked with this person on and off during the years, never once while wearing a lab coat (probably because I haven’t worn a lab coat since freshman chem and certainly wouldn’t out in public), I’m very surprised that they still imagine me that way. I guess it goes to show how powerful those stereotypes are.

I think I need to have a “Visit Cherish At Work” day where people can watch me sit at my computer, lab coat free.
