A philosopher, a mathematician, a chemist and a physicist were at coffee shop.
The physicist turns to the chemist sitting next to him and says "You know, chemistry is just applied physics!"
They all laugh a bit at the chemist.
The mathematician turns to the physicist sitting next to him and says "You know, physics is just applied mathematics!"
They all share a laugh at the physicist.
At which point, the philosopher interjects, "And mathematics is just applied philosophy!"
The laughter roars even louder.
The mathematician turns to the philosopher and says: "That's funny. Now shut up and bring me the coffee I ordered."
Three professors (a physicist, a chemist, and a statistician) are called in to see their dean.
Just as they arrive the dean is called out of his office, leaving the three professors there.
The professors see with alarm that there is a fire in the wastebasket.
The physicist says, "I know what to do! We must cool down the materials until their temperature is lower than the ignition temperature and then the fire will go out."
The chemist says, "No! No! I know what to do! We must cut off the supply of oxygen so that the fire will go out due to lack of one of the reactants."
While the physicist and chemist debate what course to take, they both are alarmed to see the statistician running around the room starting other fires.
They both scream, "What are you doing?!?"
"Trying to get an adequate sample size!"
It's a nice day at the university, when members of the teaching staff, a physicist, a law professor, a political science professor, a chemist, and a statistician walk into an office to discover the trash can is on fire!
The political science professor says: "Don't worry! I'll take care of everything!" and proceeds to exit the room.
The physicist announces "We must put the garbage can in the fridge so that the temperature will be below the ignition temperature and therefore put itself out!"
The chemist replies "No, we must cover the garbage can so that the fire consumes all of the oxygen and, in the absence of reactants, can no longer continue!"
The law professor declares: "Please stop blaming the victim, you have yet to prove the can is indeed on fire!"
Meanwhile, the three turn around to find that the statistician is running around the room setting everything else on fire!
"What the heck are you doing??" they scream at him.
"Getting a proper sample size!"
