slack sem

attended 2 meaningless lecture. the first one was QEII. the lecturer gave us a very brief overview of QE II. too brief. din learn anything useful at all. the only that i brought out with me after lecture is,

"Reliability is equal to Quality over Time."

...... okay. then so what? never say.

the next one is even more meaningless. Living with Mathematics. The "cheemest" thing this lecture has to offer is this.

"All bird can fly. A swallow is a bird. So a swallow can fly. Is this argument valid?"
The answer is.... no. why? cos the first statement is untrue. Not all birds can fly.

That is called a syllogism (dunnoe spelled correctly or not). For syllogism to be fundamentally correct, both the 2 beginning statements must be true to give a meaningfull, and always true conclusion.

The next most cheem thing is, consider the following statement true or false.
"This statement is false." Is this statement true or false?

If it is true, then it says it must be false. If it is false, then it (which is "this statement") cannot be false and so must be true.

This is known as a self-contradictory statement.

I shall end off this entry with a popular paradox, the Russell's Paradox.

"In a certain village, there is a certain barber who shaves all those who do not shave themselves. Does the barber shave himself?"


yay... what a fulfilling lecture.
