People forget

People do forget things. But often it is just an excuse for major blunders, used if you simply didn't know the issue, didn't feel like looking it up, or just plain guessed. If you forgot some of the topics needed for the course:

In engineering, guessing is generally a bad idea. In case of doubt: Look it up!

Your mistakes are potentially dangerous. You will not just make a fool out of yourself like the "creative" genius (In Germany all advertising people call themselves "Kreative") who did the add shown below. I wonder if (s)he ever noticed.

	We do know, of course, that people behind advertising quite generally have a somewhat disturbed relation to the truth. But here we see that they are also very generous when it comes to recent technical history.
		Above, the left part of a two-page add is shown that appeared for quite some time in all major magazine in the US (around 1998). If one assumes that the SONY people look at their adds before the are printed, this beauty demonstrates very nicely that the really fundamental human achievements in this century did not make a deep impression on our "creative thinkers".
		The great-grandmother alluded too above lived about 80 years ago, i.e. around 1910 - 1920. That the quantum theory, the base of transistors was not yet quite invented, must be seen as an irrelevant detail. Unfortunately, however, the transistor itself was not invented before 1947 (by John Bardeen, Walter Brattain and William Shockley) - tough luck! "Transistors", meaning battery powered mobile radios, only hit the market in the sixties. Great-grandma, by the way, did not listen to the radio at all - it didn't exist then.
		Grandmother too, hardly enjoyed her first kiss in front of the black-and-white TV. It just barely existed, but not many people could afford it or lived in areas where there was actual broadcasting.
		Mother, that much could be true, may have listened to the stereo in the car while making-out; car radios and stereos did exist about 20 - 30 years back.
	Colour TV it appears, was not so impressive as to be mentioned. And vacuum tubes obviously never existed at all in the world of our "creative" geniuses.
