A chemistry teacher was berating the students for not learning the Periodic Table of the Elements. She said, "Why when I was your age I knew both their names and weights." One kid popped up, "Yeah, but teach, there were so few of them back then. |

A Chemical is a Substance that:
An organic chemist turns into a foul odor. |
| Organic chemistry is the study of carbon compounds; biochemistry is the study of carbon compounds that wriggle. |

If an experiment works, something has gone wrong. 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. Always keep a record of your data. It indicates that you have been working. 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. In case of doubt, make it sound convincing. Do not believe in miracles - rely on them. Teamwork is essential, it allows you to blame someone else. All unmarked beakers contain fast-acting, extremely toxic poisons. No experiment is a complete failure. At least it can serve as a negative example. Any delicate and expensive piece of glassware will break before any use can be made of it. |

A chemist walks into a pharmacy and asks the pharmacist, "Do you have any acetylsalicylic acid?" "You mean aspirin?" asked the pharmacist. "That's it, I can never remember that word." |
| A physical chemist is a student who goes to university thinking he might want to be a physicist, but gets intimated by the math. |

For hundreds of years alchemists tried to change metals such as lead into gold. Many were cheats but some like Roger Bacon, though didn't "make" gold, made many worthwhile scientific discoveries like gunpowder and optic devices and had many interesting ideas about flying machines. He is regarded by many as the harbinger of experimental science. To learn more about alchemy, click here. |

David Smillie: Little Willie was a chemist. Little Willie is no more. For what he thought was H2O, Was H2SO4. |
|
Little Willie from the mirror Licked the mercury off. Thinking in his childish error It would cure his whooping cough. At the funeral, Willie's mother Smartly said to Mrs. Brown "T'was a chilly day for Willie When the mercury went down." – Anon |

John Dalton (1766-1844) is the father of the chemical atomic theory. He proposed an "atomic theory" with spherical solid atoms based upon measurable properties of mass. The main principles of his theory: chemical elements are made of atoms; atoms of different elements have different masses; atoms of the same element have the same properties, such as weight. |

It is disconcerting to reflect on the number of students we have flunked in chemistry for not knowing what we later found to be untrue. – Quoted in Robert L. Weber, Science With a Smile (1992) |

Stephen Wright, referring to a glass of water: "I mixed this myself. Two parts H, one part O. I don't trust anybody!" "They say we're 98% water. We're that close to drowning...(picks up his glass of water from the stool)...I like to live on the edge... I bought some powdered water, but I don't know what to add to it." |

The novelist Hermann Sudermann met once Emil Fischer and started thanking him on his discovery of veronal: "You know, it is so efficient, I don't even have to take it, it's enough that I see it on my nightstand." Fischer replied: "What a coincidence, when I have problems falling asleep, I take one of your novels. As a matter-of-fact, it's enough that I see one of your wonderful books on my nightstand and I immediately fall asleep!" |
| Here is a funny chemistry story. Somebody wrote a paper about how this chemical, dihydrogenoxide, has killed over 100,000 people world wide, usually through inhalation. The story also went on that even if you wash your food you can never get this chemical off. No matter what you do you will be exposed to this very dangerous chemical every day of your life until you die. The story finished by claiming that there needs to be a government research group founded to find a solution. yada yada yada...anyhow, a local press guy got a hold of this joke, if you haven't figured it out di-hydrogen-oxide is the correct name for H2O or water. The deaths that he was quoting were from drownings. Anyhow, this local guy ran the article in a paper and started a big outcry for a government study before they realized what the story was about.....kinda funny chemistry humor. |

In 1869, Mendeleev, a Russian chemist, made a list of all the chemical elements that were known at that time, sorted according to increasing atomic mass. There were many gaps in the table, and according to them, Mendeleev was able to forecast that new elements would be found to fill the gaps. Mendeleev's discovery was possible only because of former scientific knowledge, and as a matter of fact, a German chemist called Lothar Meyer made the same discovery as Mendeleev at about the same time. For a brief look at the history of the periodic table click here. |

Lothar Meyer and Dmitri Mendeleev Mendeleyev is regarded as the primary discoverer of the periodic table. However, in 1868, Lothar Meyer, a German chemist, had prepared a table which in many respects resembled the present periodic table. He did not publish this work until after the appearance of Mendeleev's first paper on the subject in 1869. His table was very similar to that of Mendeleev, but it contained some improvements and was, perhaps, influential in causing some of the revisions made by Mendeleev in the second version of his table, published in 1870. In general, Meyer was more impressed by the periodicity of the physical properties of the elements, while Mendeleev saw more clearly the chemical consequences of the periodic law. |

About Justus von Liebig (1803-1873). One day he was approached by his assistant who all excited informed him that he had just discovered a universal solvent. Liebig asked: "And what is a universal solvent?" Assistant: "One that dissolves all substances." Liebig: "Where are you going to keep that solvent, then?" |

| Two chemists meet for the first time at a symposium. One is American, one is British. The British chemist asks the American chemist, "So what do you do for research?" The American responds, "Oh, I work with aerosols." The Brit responds, "Yes, sometimes my colleagues get on my nerves also." |

A physicist, biologist and a chemist were going to the ocean for the first time. The physicist saw the ocean and was fascinated by the waves. He said he wanted to do some research on the fluid dynamics of the waves and walked into the ocean. Obviously, he was drowned and never returned. The biologist said he wanted to do research on the flora and fauna inside the ocean and walked inside the ocean. He too, never returned. The chemist waited for a long time and afterwards, wrote the observation, "The physicist and the biologist are soluble in ocean water". |
