1, because 0 is always closed. In computer science 1 and 0 correspond to whether a transistor is opened (1) or closed (0).

A man picked up a plastic water bottle and filled it to the rim with water. He put a ketchup sachet in it and closed it up.

The man approached a woman and said, "If you can solve how this works, I'll give you a dollar."

The man said "down" and the sachet of ketchup suddenly went down. Then he said "up" and it went up. Then he said "down", and when it was halfway down, he said "stay" and it stayed.

You have a iron rod with length of 1 lightyear. Now, suppose you pushed one end of the rod. About how much time will pass before the other end moves?

Following are possibilities, which one would be correct and why?
a) One year
b) Instantly
c) One week
d) More than 1000 years

First Clue: this is not related to the area of a circle (pi r squared). What's interesting about pi, is that it comes in 2 forms: digital (3.14159....) and degrees of a 1/2 circle (180 degrees). And a sine wave is an incredibly beautiful curve found everywhere in nature.

Once you get the answer, memorize it and how you arrived at it. And it will serve as a reference for problem solving in wave mechanics.

Remember, according to the De Broglie Wave Equation, everything in the entire Cosmos travels as both a wave and a particle. And sine waves, or approximations to sine waves, are the standard form of travel representing everything from light waves, sound waves, to waves on an ocean.

The study of wave mechanics will then lead you to the understanding of Fourier Analysis/Transformation, noise cancellation head phones, and unlimited adventures in science and math.

Moral of the story: Sine Waves rule! And to figure out how powerful they are you must know how to integrate the area/volume.
Second Clue: "integrate".

In Mrs. Sharma's Science class, they are holding a contest. She has a glass bottle, and a little bronze ball, the size of which is the exact same as the hole in the bottle. Mrs. Sharma is giving the student who can put the ball in the bottle, without breaking the glass or destroying the ball somehow and get an iPOD.

In her room there is a microwave, petroleum jelly, a stove, and a freezer.

Six of her seven students attempted this feat, but with no luck.

After the sixth student, the seventh, Gagan, comes up to the bottle and the ball. He thinks of using one of the tools in Mrs. Sharma's room at his disposal, and uses one (not the jelly as it was already proven to not work) and five hours later, gets the ball in the bottle and his free iPOD.
