I just though of something.

Before mine by just a bit....I don't even remember about WWII since I wasn't born until 1950.  I know about the Nazis, too.  These days The Muslims are going nutso and we a lot of folks here in the States don't like any of them just because they are Muslims.  Most all are not fanatics.  Most are just normal people trying to make lives for themselves.

Biology was such a great course to take in school. Remember dissecting frogs?....

[LizStreithorst]

With their little beating hearts still a thumpin' away.  Yes. I remember.  I only did it because it was forced on me.  I suppose if I'd had guts I'd have refused.

I remember my lab partner.....  good thing it was biology class.

Antoine Lavoisier

Discoverer of oxygen.
Beheaded in the French revolution.

The concept of mass conservation is widely used in many fields such as chemistry, mechanics, and fluid dynamics. Historically, mass conservation was discovered in chemical reactions by Antoine Lavoisier in the late 18th century, and was of crucial importance in the progress from alchemy to the modern natural science of chemistry.

I dissect fish every chance I get!

[LizStreithorst]

Dead stuff, yes.  You're looking for answer when you dissect something dead.  The answer might help the other fish. 

The frog with the beating heart was brutal.  I've been involved in many animal surgeries.  Some on my own animals.  I can handle it if good is hoped to come of it.  That frog with the beating heart they made us do was just making a live animal die so we could see a beating heart.  The lesson was painful emotionally and had no value to me.  I was such a quiet little mouse back then.  I did it was expected of me.

I dissected a frog last year . It was so COOL. The girls were grossed out but that was to be expected.

[LizStreithorst]

Was it dead and reeking of formaldehyde or was it's little heart still beating?

[BillT]

Normally a frog would be pithed or it head would be chopped off before looking at the heart.
This removes any possibility of them feeling anything.
If they didn't do this, they probably did it wrong in some way.

A frogs heart (and the hearts of many vertebrates) can beat without a functioning brain.
I have had hearts of embryonic fish beating in tissue culture (without any body attached) for days.

[LizStreithorst]

They had been pithed.

[BillT]

To me, the pithing is kind of brutal, but not the stuff after that.

[Ron Sower]

Pithed off for sure!

Ours was dead.
