Where I continue speaking of the rude lay scientific crowd…
One case on this rudeness came from a post I saw about the strange effect about hot water freezing before cold water.
It seems to defy some Law of Thermodynamics but it has been recorded.
Before some people actually clinked the link and read the article, many were quick to point out that it defied said Law and it flew in the case of common sense. One astute commenter with a wealth of historical knowledge claimed that this thing had been “disproven” too many times to enumerate.
Wow! That’s one mighty hefty claim.
Had these people actually bothered to read the article, it was about the Mpemba effect. He was a youth in Tanzania who was entering an ice-cream making contest but had forgotten to put his water in the freezer before going to school or something. When he discovered he oversight, he realized there was no time to make the ice. At least not the regular way. So, he used hot water instead – remembering an “old wives’ tale” – and he had time enough to make the ice and make the ice-cream.
This story would have been lost to history had the young man not asked a visiting scientist, Dr. Denis G. Osborne, physicist at the nearby university, the explain it.
Skeptical – of course! – Dr. Osborne returned to his lab and attempted the experiment. Surprisingly, the hot water froze faster!
Further experimentation showed it did not happen in every case but often enough that they co-authored a piece in “Physics Education” on what has become known as the Mpemba Effect.
Many have tried and re-created the experiment but no one has yet to determine WHY it works sometimes and doesn’t work other times.
Unaware of this minor little thing called “science”, many commenters attacked the poster and other commenters as being “idiots”.
One should learn to investigate before mudslinging, huh?
