The electric engineers declared for long
That flowing current can do mathematics
But they had many other head aches too.
They had to maintain correct current levels
In the eight parallel metal wires.
This is like controlling levels
Of water in parallel canals.
Even before the computers were invented
The engineer experimented for long years
With current carrying wires
He tried many different ways
For connecting the positive and negative ends.
One way is “join positive wire of the first cell
To the negative of the second cell,
Join positive of second cell to negative of third cell
And so on for any number of cells
And finally connect the positive of last cell
To negative of first cell to complete the full circuit”.
The voltage level for whole circuit
Was the sum total of voltages of all the cells.
Another way is knotting all positives at one end,
Knotting all negatives at another end
And completing an outer circuit
Between the big positive knot
And the big negative knot
If five cells of same voltage
Were to be connected in that way
The voltage would not increase
But the current fivefold would increase sure.
If several current carrying wires are joined
At one converging point
And some wires carry the currents inward
While some carry the “juices” outward
Then there is the famous “Kirchoff’s rule”.
The sum of currents flowing into the notch
Would equal the sum of currents
Flowing outward and away.
The electric engineer befriended the mathematician
They worked together to use
George Boole’s “binary mathematics”.
Here in Boole’s mathematics
The numbers 0 and 1
Are the only numbers which exist.
They both are enough to solve
All the world’s mathematics!
In George Boole’s mathematics
There are no such numbers
Like 2,3,4,5, and 6!
When we add large ordinary numbers
We do the “carry one” operation
Several times till the end .
Same thing in binary mathematics.
We write one string below the other
And do the “carry one” operations
As many times as required.
(Binary strings mean only the 010101 strings)
But the “carry one” operations
Done here are a little different.
“1 plus 0” means “sum is 1 and carry is 0”.
“1plus 1” means “sum is 0 and carry is 1.
“1 plus 1 plus ‘carry 1’ (coming from previous step)
Means “ sum is 1 and the carry is 1”
