I have a better example than a tattoo.Answer: Because you're scared of the pain a cover-up of your solar system tattoo?
Cool article! However, nothing in it suggests what has been taught in HS chemistry classes was wrong. Hydrogen bonds still hold molecules together.I don't know. I don't teach chemistry. However, perhaps THIS is an example of the type of new knowledge he was referring to.
It was part below that suggests it may have been taught differently. BTW he teaches graduate chemistry classes at a public university not high school. Are you trying to make an argument that Chemistry is a static science and has not made significant changes over the last 20 or 30 years?Cool article!

"Krylov and her colleagues demonstrated that protons are not obligated to travel along hydrogen bonds, as previously believed. The finding suggests that protons may move efficiently in stacked systems of molecules, which are common in plant biomass, membranes, DNA and elsewhere."
Yes we are in agreement to suggest that "everything" (or even most things) taught twenty years ago was wrong would be absurd.Right, when hydrogen bonds ("roads") are absent, they make their own "roads." To suggest that everything taught twenty years ago was wrong, is absurd.
So why did you paraphrase your friend, when you said this:Yes we are in agreement to suggest that "everything" (or even most things) taught twenty years ago was wrong would be absurd.
I have never insisted on that.I think you guys insisted it was a planet too at one time, so I wouldn't talk.
And that never has been the question. The question was: What do you mean when saying "planet".The question shouldn't be: "Why do I think Pluto is our ninth planet?"
So why did you paraphrase your friend, when you said this:
"Reminds me of what a co-worker of mine said, who is a college chemistry teacher. "I spent the first 20 years flunking students for not knowing, what we now know is wrong." He was exaggerating a bit, but he was sincere in his sentiment."
Sounds like you're talking out both sides of your mouth.
Because when I point out that, for 76 years, reality dictated Pluto to be considered our ninth planet, I get some educated propaganda that equates to: "No it didn't".
I would say YES.Saturn is our sixth planet from the sun.
Is this reality?
Just YES or NO please.
Anything else will be considered as an attempt to confuse - not clarify - the issue.
Scientists make mistakes. But thats human.All that after-the-fact.
Remember Thalidomide?
Assuming Thalidomide was a mistake, it was one of the most notorious after-the-fact tragedies around.
While scientists were leaning on Frances Kelsey to okay it in the United States, children in the wombs* were mutating.
(But then we're mutants anyway, aren't we? )
* That would be "fetuses" to the educated.
Honorable mentions are the Titanic and the Hindenburg.
But scientists look forward to eventually being shown to be wrong.Scientists arent "special" in this regard. Why would they be?
Do they?But scientists look forward to eventually being shown to be wrong.
They go through this elaborate method to establish how right they are; then look forward to being shown wrong with another discovery.
No.Do you look forward to being wrong, av?
