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.
Chemist's last words
1) And now the tasting test ...
2) And now shake it a bit ...
3) In which glass was my mineral water?
4) Why does that stuff burn with a green flame?!?
5) And now the detonating gas problem.
6) This is a completely safe experimental setup.
7) Now you can take the protection window away ...
8) Where do all those holes in my kettle come from?
You enter the laboratory and see an experiment. How will you know which class is it?
If it's green and wiggles, it's biology.
If it stinks, it's chemistry.
What did one lab rat say to the other?
I've got my scientist so well trained that every time I push the buzzer, he brings me a snack.
The National Institutes of Health have announced that they will no longer be using rats for medical experimentation. In their place, they will use attorneys. They have given three reasons for this decision:
1. There are now more attorneys than there are rats.
2. The medical researchers don't become as emotionally attached to the attorneys as they did to the rats.
3. No matter how hard you try, there are some things that even rats won't do.
