Quotes about the profession in general:
What in the world ISN'T chemistry? Unknown
Chemistry ought to be not for chemists alone. Miguel de Unamuno (1972)
The Tragic Sense of Life, Princeton U.
A mosquito was heard to complain
"A chemist has poisoned my brain."
The cause of his sorrow was paradichloro-
diphenyltrichloroethane.
Two sodium atoms were walking along the street when one stops and says,
"Oh my goodness, I think I've lost an electron!" "Are you sure?" asks his
companion. "Yes," replies the first sodium atom. "I'm positive." or
the equivalent:
Two ions are talking to each other in a solution. One says: "Are you a
cation or an anion?" To which the other replys, "Oh, I'm a cation." The
first asks, "Are you sure?" The reply, "I'm positive."
"What is zinc?" That's what you do if you can't zwim.
"Why do chemists use nitrates?" Because they are cheaper than day rates.

A chemistry Fairy Tale:
-
If you look closely (at this chart) you can see
-
the electrons whirring around the nucleus... (?)
-
If you look hard, you can see fairies...(!)
-
I have seen miracles,

I have seen ghosts,
-
I have seen angels,

A Lesson
-
Jesus took his disciples up the mountain and,
-
gathering them around him, He taught them saying:
-
Blessed are the poor in spirit.
-
Blessed are those who mourn.
-
Blessed are the meek.
-
Blessed are those who hunger and thirst for righteousness.
-
Blessed are the merciful.
-
Blessed are the pure in heart.
-
Blessed are the peacemakers.
-
Blessed are those who are persecuted for righteousness' sake.
-
Blessed are you when men revile you on my account.
-
Rejoice and be glad, for your reward is great in heaven.
-
Then Simon Peter said, "Are we supposed to know this?"
-
And Andrew said, "Do we have to write this down?"
-
And James said, "I don't have any paper."
-
And Phillip said, "Will we have a test on this?"
-
And Bartholomew said, "Do we have to turn this in?"
-
And John said, "The other disciples didn't have to learn this."
-
And Matthew said, "May I go to the bathroom?"
-
And Judas said, "What does this have to do with real life?"
Then one of the Pharisees who was present asked for Jesus' lesson plan
and inquired of Jesus, "Where are your anticipatory set of goals and objectives
in the cognitive domain?"
-
And Jesus wept. Author unknown
And some pertinent ones about physical
chemists:
Comment by a physical chemist on being shown a successful experiment:
"That's all very well in practice, but will it ever work in theory?"
G.
Hill, Education in Chemistry, 1992(1), 28.
Physical Chemistry is the study of theories in chemistry.
Chemistry is the study of matter and all its aspects.
Since all science involves matter, and anything interesting in science
involves theory,
a physical chemist can study anything interesting in science.
Physics is the taking of very accurate measurements on impure and poorly
defined materials.
Chemistry is characterized by sloppy measurements on very pure materials.
Thus Physical Chemistry is sloppy measurements on impure materials.
Although they like to think of themselves as the only ones
making very accurate measurements on very pure materials. Reed Howald,
Montana State U.

-
Q. Do we have to know this?
-
A. Yes
-
Q. Is this going to be on the exam?
-
A. Maybe
-
Q. Is there something I can do for extra credit?
-
A. These are offered throughout the course. Do them when offered or accept
the consequences.
-
Q. You're kidding about all this - I mean the "time" stuff, the "organization",
"keeping up" and all that?
-
A. No.
-
Q. No, really. This is just to scare us?
-
A. No.
-
Q. But this doesn't give me time for my other classes.
-
There's a longer answer here.
-
Q. I missed class this morning. Did you do anything important?
-
A. Yes
-
Q. I have to study for an exam in another class; are you going to cover
anything important?
-
A. Yes
-
Q. Are you busy?
-
Yes, but I'll always try to make time for your questions - once.
-
Q. WHY do we have to know this?
-
A. Employers expect a SUNY degree to mean you have learned it.
-
If you haven't, there are consequences for us both.
-
Q. What does this stuff have to do with being a (doctor, lawyer, native
american leader, etc.)?
-
A. You will find out (I hope.).
-
Q. Are you going to collect the homework? Sometimes.
-
Q. Is there going to be a final; is it comprehensive? Yes
-
Q. How can this be wrong when my calculator gave me that answer?
-
There is no substitute for the calculator between your ears.
-
Q. Will the test problems be like your examples?
-
A. No. I worked those problems to distract you.
-
Q. Will we have to report our answers to the proper number of significant
figures?
-
A. No. Just like in lab, only your instructor knows the proper number of
significant figures to use.
-
Q. Are the examinations going to be curved? No
-
Q. But I studied for (fill in number from 2-12) hours - why didn't I get
a better grade?"
-
How and when did you study? Did you read the book? Etc., etc.
-
Q. How about students in lab who ask (with a thermometer in their hand
. . .)
-
"How do we measure room temperature?"
-
I really like the method demonstrated to me by another teacher:
-
Take the thermometer out into the hall.
-
Then, with flourish, thrust the thermometer through the open doorway;
-
pause; and carefully note the reading.
-
Q. Why'd you count my answer wrong just because I got the wrong answer?
I got part of the set-up right.
-
As to the partial credit question, the math and physics professors here
have a cartoon of a bridge with a noticeable vertical gap between the two
parts of the bridge. The caption reads: "Don't I get partial credit??"
-
Q. One of my favorites from advanced inorganic was a dialog that ran "All
of this stuff is right."
-
"Yes, but it doesn't have anything to do with the question."
-
"So why didn't I get any points?"
-
"Because you didn't answer the question."
-
"But all the stuff I wrote is right (true)."
-
"Yes, but it doesn't have anything to do with the question......"

Seven Dangerous Assumptions About Lecturing
-
If your students are looking at you, they must be listening.
-
When teachers start lecturing, students start listening.
-
Students will remember the points you think are the most important.
-
Students finish listening when teachers finish lecturing.
-
Students accurately repeat what teachers tell them.
-
Students process things in the same way their teachers do.
-
If students understand and agree with the information presented, they will
apply the principles in their work.Source: INSTRUCTIONAL STRATEGIES

And tests:
The following story is true: Gotcha!
There were these two fairly average college students taking the required
chemistry course at their school one semester. They were both pretty good
at chemistry, so by the end of the course they both had A averages.
The final for this class was on a Monday. Since they were both doing well,
they figured that they could go to a party that weekend up at another school.
Well, obviously they didn't quite make it back. (Hangovers are a real bitch.)
So they decided they would tell their professor that they went up to another
school that weekend, had a flat tire on the way back, and couldn't get
help for a long time so that they just didn't get back in time.
The professor thought about it and finally decided to let them take the
final the next day. So they went home that night, studied hard, and went
to bed early. The next day they went in, the professor gave each of them
a copy of the final, and put them in separate rooms. So they started the
exam. The first page had one problem worth five points, and it was a fairly
simple problem dealing with molarity. So they figured this would be an
easy exam.
The second page also had one question. It was worth ninety-five points:
"Which tire?" Unknown

RULES OF THE LAB
-
When you don't know what you're doing, do it neatly.
-
Experiments must be reproducible. They should fail the same way each time.
-
First draw your curves, then plot your data.
-
Experience is directly proportional to equipment ruined.
-
A record of data is essential. It shows you were working.
-
To study a subject best, understand it thoroughly before you start.
-
To do a lab really well, have your report done well in advance.
-
If you can't get the answer in the usual manner, start at the answer and
derive the question.
-
If that doesn't work, start at both ends and try to find a common middle.
-
In case of doubt, make it sound convincing.
-
Do not believe in miracles---rely on them.
-
Team work is essential. It allows you to blame someone else.
-
All unmarked beakers contain fast-acting, extremely toxic poisons.
-
Any delicate and expensive piece of glassware will break before any use
can be made of it.(Law of Spontaneous Fission) Dave Coble

Are these straight from the MSDSs for these materials? Toxic Comments:
Someone down the hall from me put up a sign beside her door that says
"CAUTION: The Surgeon General has determined that doing just about anything,
anytime, anywhere can be hazardous to your health."
Oxygen is a very toxic gas and an extreme fire hazard.
It is fatal in concentrations of as little as 0.000001 ppm.
Humans exposed to these oxygen concentrations die within a few minutes.
Symptoms resemble very much those of cyanide poisoning (blue face, etc.)
In higher concentration e.g. about 20%, the toxic effect is somewhat delayed
and it takes about 2.5 billion inhalations before death takes place.
The reason for the delay is the difference in mechanism of the toxic effect
of of oxygen in 20% concentration.
It apparently contributes to a complex process called aging,
of which very little is known, except that it is always fatal.
However, the main disadvantage of the 20% oxygen concentration is the fact
that it is habit forming. The first inhalation (occurring at birth) is
sufficient to make oxygen addiction permanent. After that, any considerable
decrease in the daily oxygen doses results in death with symptoms resembling
those of cyanide poisoning.
Concentrations higher than 20% decrease the above mentioned delay. High
oxygen concentration provokes in prematurely born babies placed in incubators
a condition known as retrolental fibroplasia resulting in blindness. Lung
irritation has been reported on experimental animals exposed for several
days to high oxygen concentrations.
Oxygen is an extreme fire hazard. All the fires that were reported in the
continental U.S. for the period of the past 25 years were found to be due
to the presence of this gas in the atmosphere surrounding the buildings
in question.
Oxygen is especially dangerous because it is odorless, colorless and tasteless,
so that its presence cannot be readily detected until it is too late. Richard
Graham
It should also be noted that the delayed toxic effect with 20% oxygen is
completely inhibited by the presence small amounts of a number of other
gases including CO and HCN. Allan Smith
NO: A few years ago at a Dairy Queen in Ottawa, a young clerk on
the night shift was found dead by the morning shift. He'd been breathing
nitrous oxide from the cylinder used to make whipped cream; apparently
he'd stuck the tank nozzle in his mouth. The gas expansion had cooled the
nozzle, of course, and his lips froze to it; his lungs ruptured shortly
afterwards. Not exactly a laughing matter, though I suppose it makes a
fairly graphic demonstration of how gas laws can be relevant to the Real
World. Joel polowin@hyper.com
And then there is H2O:
When I was teaching a lab as a GTA, one of the students apparently didn't
see the word "with" when reading the lab manual, which instructed the students
to "dilute with distilled water". The student walked to the end of the
lab bench, where there were large carboys labeled "DISTILLED WATER". She
looked at the label on the carboy for a second, then asked me "Is this
concentrated or dilute distilled water?" I smiled a little, then said "It's
55 molar, so I would say it is pretty concentrated." When it was obvious
that she didn't get the joke, I explained it to her. Sometimes these students
just have no sense of humor whatsoever.... :-) James H. Burness, Penn

Ban Dihydrogen Monoxide!! THE INVISIBLE KILLER:
Dihydrogen monoxide is colorless, odorless, tasteless, and *kills* uncounted
thousands of people every year. Most of these deaths are caused by inhalation
of DHMO, but the dangers of dihydrogen monoxide do not end there. Symptoms
of DHMO ingestion can include excessive sweating and urination, and possibly
a bloated feeling, nausea, vomiting and body electrolyte imbalance. For
those who have become dependent, DHMO withdrawal means certain death.
DIHYDROGEN MONOXIDE:
-
is also known as hydric acid, and THE major component of acid rain.
-
contributes to the greenhouse effect.
-
may cause severe burns.
-
accelerates corrosion and rusting of many metals.
-
may cause electrical failure and decreased effectiveness of automobile
brakes.
-
has been found in excised tumors of terminal cancer patients.
CONTAMINATION IS REACHING EPIDEMIC PROPORTION!
Quantities of dihydrogen monoxide have been found in almost every stream,
lake and reservoir in America today. But the pollution is global, and the
contaminant has even been found in Antarctic ice. In the Midwest alone
DHMO has caused *millions* of dollars in property damage.
DESPITE THE DANGER, DIHYDROGEN MONOXIDE IS OFTEN USED:
-
as an industrial solvent and coolant.
-
in nuclear power plants.
-
in the production of Styrofoam.
-
as a fire retardant.
-
in many forms of cruel animal research.
-
in the distribution of pesticides. Even after washing, produce remains
contaminated by this chemical.
-
as an additive in certain "junk-foods" and other food products.
-
Waste DHMO is allowed to pollute our precious lakes, rivers, streams and
the ocean itself. The impact of wildlife is extreme, and we cannot afford
to ignore it any longer!
THE HORROR MUST BE STOPPED!
The American government has *refused* to ban the production, distribution,
or use of this damaging chemical due to its "importance to the economic
health of this nation." In fact, the navy and other military organizations
are conducting experiments with DHMO. Unknown
