chemistry is boring
IT'S OFFICIAL : CHEMISTRY LECTURES ARE A YAWN.
October 9, 1995
A scientist has come up with proof of something students have known for years -- chemistry lectures are boring. In an article published in the current issue of Chemistry in Britain, a university chemistry lecturer introduced a guest lecturer to a class of 50 doctoral candidates.
Then, he and his colleagues studied variations in what he calls the HTFDR -- "head-to-floor distance reduction." After about an hour , the average HTFDR dropped from 135cm to 121cm, said the author of the study, who preferred to remain anonymous.
The HTFDR immediately bounced back to normal when the speaker uttered the magic words: "And in conclusion . . ."

jokes of science 01
At the physics exam: 'Describe the universe in 200 words and give three examples.'
Q: What do physicists enjoy doing the most at baseball games?
A: The 'wave'.
The Stanford Linear Accelerator Center was known as SLAC, until the big earthquake, when it became known as SPLAC. SPLAC? Stanford Piecewise Linear Accelerator.
A student recognizes Einstein in a train and asks: Excuse me, professor, but does New York stop by this train?
Researchers in Fairbanks Alaska announced last week that they have discovered a superconductor which will operate at room temperature.
The answer to the problem was "log(1+x)". A student copied the answer from the good student next to him, but didn't want to make it obvious that he was cheating, so he changed the answer slightly, to "timber(1+x)"
One day in class, Richard Feynman was talking about angular momentum. He described rotation matrices and mentioned that they did not commute. He said that Sir William Hamilton discovered noncommutivity one night when he was taking a walk in his garden with Lady Hamilton. As they sat down on a bench, there was a moment of passion. It was then that he discovered that AB did not equal BA.
Why did the chicken cross the road? Albert Einstein: Whether the chicken crossed the road or the road crossed the chicken depends on your frame of reference.

ideas about science
The beguiling ideas about science quoted here were gleaned from essays, exams, and classroom discussions. Most were from 5th and 6th graders. They illustrate Mark Twain's contention that the 'most interesting information comes from children, for they tell all they know and then stop.
Q: What is one horsepower?
A: One horsepower is the amount of energy it takes to drag a horse 500 feet in one second.
You can listen to thunder after lightning and tell how close you came to getting hit. If you don't hear it, you got hit, so never mind.
Talc is found on rocks and on babies.
The law of gravity says no fair jumping up without coming back down.
When they broke open molecules, they found they were only stuffed with atoms. But when they broke open atoms, they found them stuffed with explosions.
When people run around and around in circles we say they are crazy. When planets do it we say they are orbiting.
Rainbows are just to look at, not to really understand.
While the earth seems to be knowingly keeping its distance from the sun, it is really only centrificating. [this guy is going to do well in college! *haha* ...Lj]
Someday we may discover how to make magnets that can point in any direction.
South America has cold summers and hot winters, but somehow they still manage.
Most books now say our sun is a star. But it still knows how to change back into a sun in the daytime.
Water freezes at 32 degrees and boils at 212 degrees. There are 180 degrees between freezing and boiling because there are 180 degrees between north and south.
A vibration is a motion that cannot make up its mind which way it wants to go.
There are 26 vitamins in all, but some of the letters are yet to be discovered. Finding them all means living forever.
There is a tremendous weight pushing down on the center of the Earth because of so much population stomping around up there these days.
Lime is a green-tasting rock.
Many dead animals in the past changed to fossils while others preferred to be oil.
Genetics explain why you look like your father and if you don't why you should.
Vacuums are nothings. We only mention them to let them know we know they're there.
Some oxygen molecules help fires burn while others help make water, so sometimes it's brother against brother.
Some people can tell what time it is by looking at the sun. But I have never been able to make out the numbers.
We say the cause of perfume disappearing is evaporation. Evaporation gets blamed for a lot of things people forget to put the top on.
To most people solutions mean finding the answers. But to chemists solutions are things that are still all mixed up.
In looking at a drop of water under a microscope, we find there are twice as many H's as O's.
Clouds are high flying fogs.
I am not sure how clouds get formed. But the clouds know how to do it, and that is the important thing.
Clouds just keep circling the earth around and around. And around. There is not much else to do.
Water vapor gets together in a cloud. When it is big enough to be called a drop, it does.
Humidity is the experience of looking for air and finding water.
We keep track of the humidity in the air so we won't drown when we breathe.
Rain is often known as soft water, oppositely known as hail.
Rain is saved up in cloud banks.
In some rocks you can find the fossil footprints of fishes.
Cyanide is so poisonous that one drop of it on a dogs tongue will kill the strongest man.
A blizzard is when it snows sideways.
A hurricane is a breeze of a bigly size.
A monsoon is a French gentleman.
Thunder is a rich source of loudness.
Isotherms and isobars are even more important than their names sound.
It is so hot in some places that the people there have to live in other places.
The wind is like the air, only pushier.
