So, just admit it - all that talk of being an "engineer" is a lie. It is like in the USA, when someone says that they "do construction", it often means "deal drugs". (No offense to the actual hardworking men and women who actually do construction, as also to real engineers) > > you willnever find the above ful dimension analysis !! Of course I will - I did it myself a day ago. We do simple problems like this all the time in general chemistry I. If students can't do these kinds of problems, they fail. > you know why prof. Dulitle?? Because you're stupid? > > because such simple analysys as NEVER DONE > IN ANY BOOK!! It is in some books. The only reason it is omitted is that the problem is too trivial for an advanced text. > un;ess you or someone else show it andf quoteit > without hand wavings Who needs hand waving - I did it for you in SI (Systeme International) units, and artful just did it for you in general units.

This is when they are 13 or 14 years old. Maybe you can go back to high school and learn this. Probably not, though. > BTW > without releasing Dulitle from that > 9since he gave me the advice to look in books > i ask him tell me exactly** where** > or else -- a single example for that !!!) > > invite any other sane person HERE > to so us a quote about that > photon momentum dimestion analysys "Digestion analysis" - watching what you eat, eh? > INCLUDING ALL ITS DIMENSION LESS FIGURES !!!

I will NOT teach you this basic skill. You will have to go back and instruct yourself in it again, WITH A BOOK, before I'd even engage with you on it. Nor would I teach you how to add or subtract if you demonstrated that you didn't know how to do that reliably either. I would expect you to stop claiming you know how to add and subtract until you actually learn how to do it. Your taunts to show you how *I* would add and subtract would similarly go ignored. PD
