George Francis Fitzgerald

Died 21 Feb 1901 at age 49 (born 3 Aug 1851).Irish physicist whose suggestion of a way to produce waves helped lay a foundation for wireless telegraphy. He also first developed a theory, independently discovered by Hendrik Lorentz, that a material object moving through an electromagnetic field would exhibit a contraction of its length in the direction of motion. This is now known as the Lorentz-FitzGerald contraction, which Albert Einstein used in his own special theory of relativity. He also was first to propose the structure of comets as a head made of large stones, but a tail make of such smaller stones (less than 1-cm diam.) that the pressure of light radiation from the sun could deflect them. FitzGerald also studied electrolysis as well as electromagnetic radiation.«

FBI agents conducted a raid of a psychiatric hospital that was under investigation for medical insurance fraud.
After hours of reviewing thousands of medical records,
the dozens of agents had worked up quite an appetite.
The agent in charge of the investigation called a nearby pizza parlor
with delivery service to order a quick dinner for his colleagues.
The following telephone conversation took place:
Agent: Hello. I would like to order 19 large pizzas and 67 cans of soda.
Pizza Man: And where would you like them delivered?
Agent: We're over at the psychiatric hospital.
Pizza Man: The psychiatric hospital?
Agent: That's right. I'm an FBI agent.
Pizza Man: You're an FBI agent?
Agent: That's correct. Just about everybody here is.
Pizza Man: And you're at the psychiatric hospital?
Agent: That's correct. And make sure you don't go through the front doors.
We have them locked.
You will have to go around to the back to the service entrance to deliver the pizzas.
Pizza Man: And you say you're all FBI agents?
Agent: That's right. How soon can you have them here?
Pizza Man: And everyone at the psychiatric hospital is an FBI agent?
Agent: That's right. We've been here all day and we're starving.
Pizza Man: How are you going to pay for all of this?
Agent: I have my checkbook right here.
Pizza Man: And you're all FBI agents?
Agent: That's right.
Everyone here is an FBI agent.
Can you remember to bring the pizzas and sodas to the service entrance in the rear?
We have the front doors locked.
Pizza Man: I don't think so.
