Um..Dan?



your article states the following (cut and pasted) "and he decided to make the boiling point of water zero degrees and the freezing point of water 100 degrees"



Freezing was zero, and boiling 100 inthe °C scale..I am unaware of anyone using a lower number in any system for the boiling point (at lest in any system that caught on.

I know you are generally infallible (to the point I am begining questioning the °C scale...and I am a Canadian!)

But can you clarify?

You repeat that statement later in the article..

Look under history in this link:

More things I didn't know.

I looked Paul

and even the almighty Wiki says freeze = 0 , boil = 100.

sometimes

you can't find that screw drivers thats right in front of you??

I'd assume dan just didn't 'see' the mistake right in front of him?

Celsius

Keep Reading.....

Under History:

"In 1742, Anders Celsius (1701 – 1744) created a "reversed" version of the modern Celsius temperature scale whereby zero represented the boiling point of water and one hundred represented the freezing point of water."

Looks like Dan got it right. - DF

NOVA

It was also mentioned on the NOVA show " Absolute Zero" on PBS that when Celsius first created his thermometer boiling was zero and 100 was freezing. It was later reversed to match the other popular thermometers of the time

is Heating and Ventilating Buildings by Rolla C. Carpenter, M.S., C.E., M.M.E. He was the Professor of Experimental Engineering at Cornell University and was also one of the early presidents of the American Society of Heating and Ventilating Engineers, which became ASHRAE. He wrote this book in 1901. I've attached the pages for your files.

In 1742, Celsius was using zero as boiling and 100 as the freezing point. See page 2 of the PDF.

SEE..I told you Dan is NEVER wrong!

Thanks for the information...messes my mind though

Dan thought.....

.....he was wrong once.


Turned out he was mistaken........
