IAS increases upon entering a thermal, but nobody *really* knows

no experimentation has been done to figure it out. Some wise old

out there are certain of their explanation, and maybe they're right,

maybe it's just bad air.
This seems like it would be a good youth-in-soaring sort of question

solve with real science.

This ain't rocket science it is basic aerodynamics. Experimentation
is worthless without a basic understanding of aerodynamic force. You
will only propagate the narrow minded misinformation found in some real
science books. Its takes life long conspiracy to get pilots (private
and commercial) so ignorant about aerodynamic force that they do not
know the simple single difference between the definition of lift and
drag. You have to start when they are young and gullible and hope they
do not practice much original thought or apply what you tell them with
actual occurrence.

I hate to brag but I am a walking talking aerodynamic experiment. Why
even in my sleep I possess the ingredients for aerodynamic force. I am
a solid object that is influenced by a relative airflow 24-7 as a
result of respiration among other things. Not to mention other fluid
flows like blood and urine. And I have been known to emit a little
swamp gas (what you refer to as "bad air"). To the people that I am
related to this is referred to as relative wind.

LOL

Guess you're right Spock pun intended ;-) , the current fashion is to
eschew science in favor of "common" sense.
