Don't LOOK at anything in a physics lab.
Don't TASTE anything in a chemistry lab.
Don't SMELL anything in a biology lab.
Don't TOUCH anything in a medical lab.
and, most importantly:
Don't LISTEN to anything in a philosophy
The First Law of Philosophy: For every philosopher, there exists an equal and opposite philosopher.
The Second Law of Philosophy: They're both wrong.
A philosophy professor walks in to give his class their final. Placing his chair on his desk the professor instructs the class, "Using every applicable thing you've learned in this course, prove to me that this chair DOES NOT EXIST."
So, pencils are writing and erasers are erasing, students are preparing to embark on novels proving that this chair doesn't exist, except for one student. He spends thirty seconds writing his answer, then turns his final in to the astonishment of his peers.
Time goes by, and the day comes when all the students get their final grades ... and to the amazment of the class, the student who wrote for thirty seconds gets the highest grade in the class.
His answer to the question: "What chair?"
Final philosophy exam:
Is this a question?
If this is an answer!
The teacher of the earth science class was lecturing on map reading.
After explaining about latitude, longitude, degrees and minutes the teacher asked, "Suppose I asked you to meet me for lunch at 23 degrees, 4 minutes north latitude and 45 degrees, 15 minutes east longitude?"
After a confused silence, a voice volunteered, "I guess you'd be eating alone."
Rules of the lab
1) If an experiment works, something has gone wrong.
2) When you don't know what you're doing, do it neatly.
3) Experiments must be reproduceable, they should fail the same way each time.
4) First draw your curves, then plot your data.
5) Experience is directly proportional to equipment ruined.
6) Always keep a record of your data. It indicates that you have been working.
7) To do a lab really well, have your report done well in advance.
8) If you can't get the answer in the usual manner, start at the answer and derive the question.
9) In case of doubt, make it sound convincing.
10) Do not believe in miracles--rely on them.
11) Team work is essential, it allows you to blame someone else.
12) All unmarked beakers contain fast-acting, extremely toxic poisons.
13) No experiment is a complete failure. At least it can serve as a negative example.
14) Any delicate and expensive piece of glassware will break before any use can be made of it.More jokes
