I experiment. Magic trick

Let's do a "magic" experiment.

The game:

It is an example to foresee numbers between 0 and 63

You need these letters

(We leave some reader crush you, to design a few nicer stage to us)

You will have to forgive me, but a kind reader has indicated me that one has strained an error to me in the LETTER 2. Where it puts 8 it must put 6

Now you ask your "victim" to choose a number between 0 and 63

Later you are teaching him the letters and ask him if his number is in each of them.

If he says to you that yes, you should plunge mentally the first number of the letter.

When you have taught him all the letters, the sum that you have done will be the elected number.

Let's do an example.

The elected number will be 47

Is it in the first letter? Yes (I plunge 1)

Is it in the second letter? Yes (I plunge 2, whole 3)

Is it in the third letter? Yes (I plunge 4, whole 7)

Is it in the fourth letter? Yes (I plunge 8, whole 15)

Is it in the fifth letter? Not (I do not plunge 16, I am still conl 15)

Is it in the sixth letter? Yes (I plunge 32, whole 47!!)

Ta chaaaaan!!

And now the explanation

In the conjuring tricks, when they "foresee" something to you it is for one of these two skills. Or they force you to choose what they want, or force you to reveal your election.

In our case... they have made you "sing" the number as a goldfinch... gullible!

"If I have not said anything..." - you will protest.

Yes, son yes... what it spends is that you speak in BINARY.

You have said: Yes, yes, yes, yes, Not, Yes...

What can be understood like 1,1,1,1,0,1

47 in binary is 101111... This way of simple.

How to do the letters

In the first letter you put all the numbers that they have the first bit to one

In the second letter those that they have the second bit to one... etc.

Here you have a table of the first 64 numbers in binary

With this you can already do to yourself yourself the letters that you want, according to up to the number that you want to cover. With one more letter you can come up to 100 (in particular up to 127), but you have to include more numbers in the six first ones using the skill that we have described.

That you amuse yourself!!
