Physics jokes

Do you know a good one? Send me. :)


A neutron walked into a bar and asked, "How much for a drink?" The bartender replied, "For you, no charge."

Two atoms were walking across a road when one of them said, "I think I lost an electron!" "Really!" the other replied, "Are you sure?" "Yes, I 'm absolutely positive."

Here is a teaching tip for physics professors: When a student tries to paraphrase something you have just taught, feed her or him the following line: "I know you believe you understand what you think I said, but I am not sure you realize that what you heard is not what I meant." This will guarantee that the student will not interrupt your class again until the next semester.

This is apparently a true story. It took place just outside of Munich, Germany. Heisenberg went for a drive and got stopped by a traffic cop. The cop asked, "Do you know how fast you were going?" Heisenberg replied, "No, but I know where I am."

Q: How many theoretical physicists specializing in general relativity does it take to change a light bulb?
A: Two. One to hold the bulb and one to rotate the universe.

A student riding in a train looks up and sees Einstein sitting next to him. Excited he asks, "Excuse me, professor. Does Boston stop at this train?"

Absolute zero is cool.

Seen on the door to a light-wave lab: "CAUTION! Do not look into laser with remaining good eye."

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.
If it doesn't work, it's physics.

A theory is something nobody believes, except the person who made it.
An experiment is something everybody believes, except the person who made it.
(Albert Einstein)

A mathematician, an engineer and a physicist sat around a table discussing how to measure the volume of a cow. The mathematician suggested the use of geometry and symmetry relationships of the cow, but his idea was rejected on the grounds of being too time consuming.
The engineer suggested placing the cow in a pool of water and measuring the change in the height of the water, but his idea was rejected on the grounds of impracticality.
"It's easy," said the physicist. "We'll make an assumption that the cow is a small sphere, calculate the volume and then blow it up to the actual size."

The renowned cosmogonist Professor Bignumska, lecturing on the future of the universe, had just stated that in about a billion years, according to her calculations, the earth would fall into the sun in a fiery death. In the back of the auditorium a tremulous voice piped up: "Excuse me, Professor, but h-h-how long did you say it would be?" Professor Bignumska calmly replied, "About a billion years." A sigh of relief was heard. "Whew! for a minute there, I thought you said million years."

After Receiving an Invitation to a Physicists' Ball:

Volta was electrified and Archimedes was buoyant at the thought.
Ampère was worried he wasn't up on current research.
Ohm resisted the idea at first.
Boyle said he was under too much pressure.
Hertz promised that in the future he will attend with greater frequency.
Henry begged off due to a low capacity for alcohol.
Pierre and Marie Curie were radiating enthusiasm.
Born thought the probability of enjoying himself is pretty high.
Einstein thought it would be relatively easy to attend.
Heisenberg was uncertain whether he could make it.
Schrödinger had to take his cat to the vet, or did he?
Hawking said he'd try to string enough time together to make a space in his schedule.

Why did the chicken cross the road?

Aristotle: It is the nature of chickens to cross roads.
Issac Newton: Chickens at rest tend to stay at rest, chickens in motion tend to cross roads.
Albert Einstein: Whether the chicken crossed the road or the road moved beneath the chicken depends on your frame of reference.
Werner Heisenberg: We are not sure which side of the road the chicken was on, but it was moving very fast.
Wolfgang Pauli: There already was a chicken on this side of the road.

How many physicists does it take to change a light bulb?
Eleven. One to do it and ten to co-author the paper.

How many astronomers does it take to change a light bulb?
None, astronomers prefer the dark.

How many radio astronomers does it take to change a light bulb?
None. They are not interested in that short wave stuff.

How many general relativists does it take to change a light bulb?
Two. One holds the bulb, while the other rotates the universe.
