Re: Plasma

Make sure you note the difference to the students !
1 st I taught a general physics class and said "The Universe -- the space
between the Stars -- is filled with plasma!"
A student responded " I didn't know there was that much blood around!"

The word "plasma" is used to describe the
liquid part of blood. And in physics the same
word is used to describe a mixture of positive
and negative ions (usually electrons and positive
ions). What do biological and physical plasmas
have in common (to justify the same word)?
