Did they "dial down" Watson?

Well, Watson strutted his stuff last night, and he started out pretty strong. But as the questions got tougher, he showed some of his weaknesses with the nuances of the English language. Or did he? I have a colleague who thinks they "turned down" Watson's capabilities halfway through. What do you think? How will Watson behave tonight?

[Watson on PBS, pre-Jeopardy! showdown.]

Until then, here are the answers, or questions, rather, to yesterday's physics Jeopardy! clues of yore. Did you get them all right?

Jeopardy! Round:
A sound's repetition by reflection. What is AN ECHO?
Detection of gamma rays was 1 of the uses for this 1947 instant picture taker. What is A POLAROID-LAND CAMERA?
After length, width & depth, the 4th dimension.
($400) What is TIME?
Negative particle that orbits an atom's nucleus.
($500) What is AN ELECTRON?
Shattering sound that accompanies breaking the sound barrier. What is A SONIC BOOM?

Double Jeopardy! Round:
What we call the flow of electrons through wire, air, or even yourself. What is ELECTRICITY?
In light, 2 colors are said to be complementary if, when added together, they produce this color. What is WHITE?
Though it holds our planet together, it's actually a much weaker force than electro-magnetism. What is GRAVITY?
Invented in 1947 to improve electron microscope images, this science created a 3-D picture. What is HOLOGRAPHY?
Branch of physics dealing with motion, like the bumping of molecules in a gas. What is KINETICS?

Double Jeopardy! Bonus Round (Why not?):
In the late 19th century, scientists postulated that this travels in waves through what they called luminiferous ether. What is LIGHT?
A 1992 experiment using surface tension on polished silicon got water to defy physics by doing this. What is TO GO UP?
The second law of thermodynamics says that this will of its own accord only move to a colder object. What is HEAT?
When you press the nozzle of an aerosol can...the contents are pushed out by pressurized gas. The gas is called one of these, a general term for chemicals that create thrust. What is A PROPELLANT?
Newton said the gravitational force between 2 objects is inversely related to the square of this measurement. What is THE DISTANCE BETWEEN THE 2 OBJECTS?
Final Jeopardy! Round:
Edward Lorenz' idea of linking this creature to changes in the weather became the basis of chaos theory. What is THE BUTTERFLY?
