43Basic Proportionality Theorem


If a line is drawn parallel to one side of a triangle to intersect the other two sides in distinct points, the other two sides are divided in the same ratio.

In Boolean Algebra, there are some very important laws which are called the De Morgan's laws (the spelling can change from author to author).

These laws teach us how to interchange NOT with AND or OR logical operators.

In formal logic, De Morgan's laws are rules relating the logical operators 'and' and 'or' in terms of each other via negation:

not(p or q) =
(not p) and (not q)

not(p and q) =
(not p) or (not q)
Using logic gates (commonly used in Digital Electronics), they can be expressed in two forms:

the OR form:
De ....etc

Automated Theorem Proving
AbstractAutomated theorem proving (ATP), currently the most well-developed subfield of automated reasoning (AR), is the proving of mathematical theorems by a computer program. Depending on the underlying logic, the problem of deciding the validity of a theorem varies from trivial to impossible. ....etc

his is a very simple square wave generator circuit built with IC 74LS00 that can generate square signals with frequencies between 20 Hz and 1 MHz. Its stability is good enough for most applications. The output freq. is dimensioned through the RC components and time delay of the 3 inverter gates. The time delay of a logic gate is the elapsed time between a change of input state and the resulting change of the output state.

To prevent the temperature and voltage supply from affecting the frequency of the square wave generator, the oscillator f ....etc

THALES OF MILETUS : THALES OF MILETUS Thales of Miletus -Socratic Greek philosopher from Miletus in Asia Minor, and one of the Seven Sages of Greece. Many, most notably Aristotle, regard him as the first philosopher in the Greek tradition. According to Bertrand Russell, Western philosophy begins with Thales. Thales attempted to explain natural phenomena without reference to mythology and was tremendously influentia ....etc

Verification and interpretation of truth tables for AND, OR, NOT, NAND, NOR Exclusive OR (EX-OR), Exclusive NOR (EX-NOR) Gates.

Apparatus: Logic trainer kit, logic gates / ICs, wires.
Theory: Logic gates are electronic circuits which perform logical functions on one or more inputs to produce one output. There are seven logic gates. When all the input combinations of a logic gate are written in a series and their corresponding outputs written along them, then this input/ output combination is called ....etc
