The englisch mathematician George Boole described 150 years ago logic with mathematical formulas. He used statements that were either "TRUE" or "FALSE" and combined them with logical operations "AND", "OR" and "NOT".

Several mathematicians, among others **Augustus De Morgan**
presented, in the further course, a **set of rules**
and **completed** in that way the **Boolean algebra**.
The work however remained confined to the mathematics for a long time.

In the 1930s developed the american mathematician
**Claude Shannon** the so called
**"switching algebra"**.
He applied the Boolean algebra
to **switches** and **relays**
and was able to prove that all **logic operations**
could be **replicated** by **electrical circuits**.
This work was the breakthrough of the **digital electronics**.

In this **first part** you get to know in **20 experiments**
the Boolean variables, operations the set of rules.

In the **second part** (Go on ...) you simplify in
**10 experimenten** some
**logical problems** using Boolean Algebra.

Let's go...and have fun...
