Magic !

A magician has one hundred cards numbered 1 to 100. He puts them into three boxes, a red one, a white one and a blue one, so that each box contains at least one card. A member of the audience selects two of the three boxes, chooses one card from each and announces the sum of the numbers on the chosen cards. Given this sum, the magician identifies the box from which no card has been chosen.

How many ways are there to put all the cards into the boxes so that this trick always works? (Two ways are considered different if at least one card is put into a different box.)

This seems like a textbook question, but i want able to find it in the 6 books that I own.

Rectangle Tangle

A rectangle is cut out from another bigger rectangle. How can you divide the remaining portion into two equal parts ? Of-course, you don't have the measuring tape, where the heck these things are when you need them the most ?

An Automatic Siphon?

I installed an "automatic" siphon spillway tube in my pond. When it rains, the siphon draws the water back down to the proper level.

How does an "automatic siphon" get started?

World Record

The current world record in the men's and women's Discus Throw stands at 74.08 and 76.80 metres respectively. All other records in athletics including shot put, javelin and hammer throw is better for males.

So what's happening here ? What's the explanation ?

The big water fall

There's a place where a water fall, falls almost 400 feet over the edge and width of falls is about 3 miles. Currently there is no water falling, but there's water at the foot of the falls. When the water fall was active, it was five times size of Nigira Falls.

Where on earth are these falls, and what is it's name?

On Solving Problems

Tom appeared for a maths exam. He was given 100 problems to solve. He tried to solve all of them correctly but some of them went wrong. Any how he scored 85.
His Score was calculated by subtracting two times the number of wrong answers from the number of correct answers.

Can you tell how many problems he solved correctly ?

'kay, everyone know The Northern Lights, the first book of His Dark Materials by Philip Pullman?
Well, if you don't, too bad.

From the book, there is a certain instrument called the Alethiometer, from the greek words alethia, meaning truth, and meter, meaning measurer (not to be confused with metre, meaning measurement). And only Lyra could understand it without the "book" that tells you what the symbols mean.

Now, pretend you have the alethiometer in your hands.
You spin the dials to ask a question:

Griffin-Sun-Angel (Does magic really exist?)

And the alethiometer tells you:
(in order for this one)
Man-Tree-Anchor-Dolphin-Sun-Dolphin-Moon-Griffin-Candle-Compass-Snake-Owl-Bird-Sword and the sequence repeats.

Now, what is the answer to your question?
Answers might vary

***Even though, I might have performed very few wonders with my own alethiometer, I might not be a perfect Symbol Reader, like Lyra***

Our World

Most on Earth believe that they live in a 3-dimensional world.
Few, not very few, know that when a world is described as a x-dimensional world, x=the minimum number of coordinates needed to describe the exact location of any point in that world.
So,
regarding when a world is described as a x-dimensional world, x=the minium number of coordinates needed to describe the exact location of any point in that world,
which dimension do you think you live in and WHY?

**I just wanted to see what you make of it ^^**

Another Odd Rafting Trip

There are 8 people that need to cross the river on a raft.
Only 2 can be on the raft at a time.
There is a Red Indian Chief and his two daughters. A Cowboy with his two sons. A policeman with a criminal.
The Red Indian Chief cannot be with any of the Cowboy's sons or he will kill them, unless the Cowboy is present.
The Cowboy cannot be with any of the Chief's daughters or he will kill them, unless the Chief is present.
The policeman must be with the criminal at all times or the criminal will escape.
Only the Policeman, Chief and Cowboy know how to operate the raft.
Try getting everyone across.

SideNotes:
The Red Indian Chief and Cowboy will not kill each other. Well you can say they know they are evenly matched so fighting is pointless.
And when I mean they cannot be together, it means either together on shore or on the raft.

Well it will take a while but it is possible. Have fun. :D
