I didn't say it couldn't happen. Read the links I posted. Im not going to post 200 pages of scientific studies just to get a point across, if you choose to ignore the data that's perfectly fine by me.
With four family members with degrees in botany, not all earned at the same time in the same eras, and with the five of us owning a pot-in-pot nursery that covers roughly 17 acres of of land we have a pretty good grasp of things and of what can happen.
I never said it was a sure thing that will always happen. I also left out that at times the burn will not be because water droplets will work like a magnifying glass and focus the light rays on one small spot and instead the burn will come from an excessive amount of fertilizer sitting on one small area of a leaf, or leaves, long enough because the water droplet it is in is large enough to remain long enough for burn to occur. But it can happen regardless of what you might have read.
There is one thing about education, depending on where you are educated and what your professors believe and teach, you can take a course with the same name as someone else going elsewhere, or even just with a different professor, and be taught different things.
Not all economic majors are taught the same thing. That is why there is such an argument now in the U.S. about Obama's love of Keynesian economic and why those who were taught and believe in other economic theories say he is wrong .. which he is wrong.
Look at the two sides of the myth of man-made global warming and how each can provide differing data about the very same things that each side will swear to be 100% factual.
If you have taken philosophy courses you may have had professors who believed a certain philosopher, or several philosophers hit the nail on the head and that others totally missed the mark. That assumption would be coming from a likely intelligent person but almost certainly not someone with the 190 or higher IQ that a philosopher would normally have so they might not fully understand any of them and aren't actually qualified to say who was right or wrong, or maybe better said who was more correct and who was less correct.
You can find contradictory 'scientific evidence' for many things. Personally, I tend to believe what my family members were taught, what I have read and what we have all witnessed.
If you prefer to believe otherwise, that is of course your prerogative. As I said, possibly N.C. State University did instruct my family members incorrectly and possibly what I have read could have been wrong ... but at the same time it is equally possible that what you have read was incorrect regardless of its source.
Not all scientists in each and every field fully agree with each other on every topic, but each will preach and profess what they believe to be accurate as if there is no question whatsoever that they might possibly be inaccurate, or at least partially inaccurate.
