Two blood cells met and fell in love. Alas, it was all in vein.

A clever wordplay with the words “vein” and “vain”.

Pavlov is sitting at a pub, enjoying a pint. Suddenly the phone rings and he jumps up shouting, “Oh no, I forgot to feed the dog!”

Pavlov is a physiologist who used to ring a bell every time he fed his dogs. After some time, he noticed that ringing the bell by its own caused salivation in his dogs, even if he didn’t offer them any food.

“I wish I was adenine, then I could get paired with U.”

In RNA (Ribonucleic acid), adenine (A) makes a “base pair” with uracil (U).

“What did one sister chromatid say to the other?”
“Stop copying me.”

“Sister chromatids” are two identical chromatids (replicated chromosomes), which are joined with each other.

What does DNA stand for? National Dyslexia Association.

Dyslexia is a reading disorder, which causes various troubles during reading, even for people with normal intelligence. If read correctly, the abbreviation for National Dyslexia Association should be NDA, not DNA.

“What did the stimulus do to the neuron after they got married?”
“It carried it over the threshold.”

The “threshold” is the depolarization level over which a stimulus must carry the neuron, in order for an action potential to be fired.

An infectious disease enters a bar. The bartender says, “We don’t serve your kind here”. The disease replies, “Well, you are not a very good host.”

The word “host” has several meanings, one of which is “a person who accommodates guests”, and another one is “an animal or a plant in which a parasite lives”.

The scientists have just found the gene for shyness. They would have found it earlier, but it was hiding behind two other genes.

“What is the fastest way to determine the sex of a chromosome?”
“Pull down its genes.”

Word play with the words “genes” and “jeans”.

One lab rat says to another:
I’ve got my scientist so well trained that every time I push the buzzer, he brings me a snack.”

“Girl, you are so hot, you denature my proteins.”

When things get hot, proteins denature, i.e. lose their shape and structure.

“What did Gregor Mendel say when he founded genetics?”

Gregor Mendel made his experiments using pea plants.

“What is sleeping brain’s favorite rock band?”

REM stands for “rapid eye movement”, which occurs during sleep.

Physics Jokes

“Where does bad light end up?”
“In prism.”

A word-play with the word “prison”.

“Why does a burger have less energy than a steak?
Because it is in its ground state.”

The ground state of a mechanical system has the least possible energy.

Einstein developed a theory about space. And it was about time too.

The joke is a wordplay with the fact that Einstein developed a theory about space-time relativity.

“Theory is when you know everything, but nothing works. Practice is when everything works, but no one knows why. In our lab theory and practice are combined – nothing works and no one knows why.”

“What is a physicist’s favorite food?”
“Fission chips.”

Fission chips” sounds like “fish’n’chips“. Fission is a radio-active process during which a nucleus splits into two or more nuclei.

Two theoretical physicists are lost at the top of a mountain. Theoretical physicist No 1 pulls out a map and peruses it for a while. Then he turns to theoretical physicist No 2 and says:
“Hey, I’ve figured it out. I know where we are.”
“Where are we then?”
“Do you see that mountain over there?”
“Well… That’s where we are!”

Theoretical physicists are regarded to be very detached from reality.

I have a new theory on inertia, but it doesn’t seem to be gaining momentum.

Inertia and momentum are related to the motions of solid bodies.

“How did Einstein begin his stories?”
“Once upon a space-time…”

The space-time is a mathematical model of the universe introduced by Albert Einstein.

Yesterday I was reading a book on anti-gravity. Couldn’t put it down.

Anti-gravity is the concept of having a place or object which is free from the force of gravity.

A cop pulls Heisenberg and asks him:
“Do you know how fast you were driving?”
Heisenberg replies:
“No, but I know where I am.”

Heisenberg’s uncertainty principle in quantum mechanics states that you can not know with certainty both the position and the momentum of a particle.

My friend Power has been very stressed all week. His boss keeps making him work over time.

A word play with the formula:

One day, Einstein, Newton and Pascal met up and decided to play a game of hide and seek. Einstein volunteered to be “It”. As Einstein counted to 100, eyes closed, Pascal ran away and hid. Newton however stood right in front of Einstein and drew a 1 meter by 1 meter square around himself. When Einstein opened his eyes, he immediately saw Newton and said, “I found you Newton,” but Newton replied, “Nope, you found one Newton per square meter, that’s Pascal!”

A word play with the formula:

A photon checks into a hotel. The bellhop asks, “Can I help you with your luggage?” The photon replies, “I don’t have any, I’m traveling light.”

Photons are traveling light particles.

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?” 

Physical observations depend on the point of view of the observer.

Why is electricity so dangerous? Because it doesn’t know how to conduct itself properly.

Electricity is formed by conduction of electrons in a wire.

A male magnet says to a female magnet:
“From your backside, I thought you were repulsive. After seeing you from the front however, I find you rather attractive.”

Depending on the way you connect magnets, they could either repulse or attract each other.

Schrodinger’s cat walks into a bar. And doesn’t.

Schrodinger’s cat is a thought experiment related to the theory that a system can be in multiple states until interacts with the outside world. The classic setup is with a cat closed in a box with radioactive substance in it, which could potentially kill her. Before you open the box, the cat is supposedly both dead and alive.

The dean addresses the physics department:
“Why do I always have to give you so much money – for laboratories and expensive equipment and stuff? Why couldn’t you be like the mathematics department – all they need is money for pencils, paper, and waste-paper baskets. Or even better, like the philosophy department – all they need is pencils and paper.”

Scientists like physicists and mathematicians consider philosophers to produce mostly useless results and materials.
