Chemistry Jokes

A chemistry teacher was scholding her 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."

'H2O is hot water, and CO2 is cold water'

Q: Why are chemists great for solving problems?

A: They have all the 'solutions'.

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".

Teacher: 'What is the formula for water?'

Student: 'H, I, J, K, L, M, N, O'

Teacher: 'That's not what I taught you'.

Student: 'But you said the formula for water was...H to O.'

"My name is Bond - Covalent Bond."

Math Humor!

This post includes a few mathematically humorous jokes and sayings that any mathematician can appreciate! The jokes contain something essential about mathematics and the mathematical way of thinking.

 Enjoy!

Q: What did zero say to eight?
A: Nice belt!!


Q: What do you call a mathematician's bird that won't eat?
                            A: A poly "no meal"


Q: How does one insult a mathematician?
A: You say: "Your brain is smaller than any ε > 0"


Q: Why do you rarely find mathematicians spending time at the beach?
A: Because they have sine and cosine to get a tan and don't need the sun!


Q: How do mathematicians induce good behavior in their children?
A: 'If I've told you n times, I've told you n+1 times...'


In some alley, a function meets up with a differential operator:
"Get out of my way - or I'll differentiate you till you're zero!"
"Try it - I'm ex..."
"Too bad... I'm d/dy."


Top ten excuses for not doing homework:
I accidentally divided by zero and my paper burst into flames.
It was Isaac Newton's birthday.
I could only get arbitrarily close to my textbook. I couldn't actually reach it.
I have the proof, but there isn't room to write it in this margin.
I was watching the World Series and got tied up trying to prove that it converged.
I have a solar powered calculator and it was cloudy.
I locked the paper in my trunk but a four-dimensional dog got in and ate it.
I couldn't figure out whether I am the square root of negative one or i is the square root of negative one.
I took time out to snack on a doughnut and a cup of coffee. I spent the rest of the night trying to figure which one to dunk.


Salary Theorem: The less you know, the more you make.
Fact #1: Knowledge is Power
Fact #2: Time is Money
We know that: Power = Work / Time
And since Knowledge = Power and Time = Money
It is therefore true that Knowledge = Work / Money
Solving for Money, we get:
Money = Work / Knowledge
Thus, as Knowledge approaches zero, Money approaches infinity, regardless of the amount of Work done


Q: How many mathematicians does it take to screw in a light bulb?
A1: None. It's left to the reader as an exercise.
A2: None. A mathematician can't screw in a light bulb, but he can easily prove the work can be done.
A3: One. He gives it to four programmers, thereby reducing the problem to the already solved
A4: The answer is intuitively obvious


Q: Why do they never serve beer at a math party?
A: Because you can't drink and derive...
