The journey of a loner in just another engineering college

From the skinny uncouth instrumentation engineering graduate to the Hep Sandy! He's probably been gymming, managed a total makeover - hep clothes, style and (something I always notice) neat footwear!

From a lecturer who couldn't in one semester explain the basics of measurement to the (ahem...) professor who explained how a sampling oscilloscope down converts the input frequency with eloquence and finesse.

From the throwing chalks and "yes you, stand up and tell me how the transducer converts the flow of water to an electrical signal" to the guy who manages to laugh at his mistakes and laugh along with us and manages a few PJs in the process.

Sandy has travelled miles, and a pretty decent journey, in my not so humble opinion!

But then there are those things that never change. Like after one of his attempts to explain a particular concept, the eerie silence is broken by a voice that says "excuse me sir" or probably just a tentative "sir" Sandy goes like "yeah"? Please note the "yeah" and not "yes" ! And by the end of it you've forgotten your question. The "yeah" has so much emotion (!!) to it that you could practically melt in his arms ;-)

It conjures the image of Sandy on his bed, thinking about some international issue, a woman half onto him *the morning after* and after some time groggily says "Sandy", part tentatively, part asleep, part not knowing she's talking to him, part wanting to say something to him (Women........!!!) and good old Sandy with all thats left of him says "yeah baby"?

And by then if you can "Sir, wouldn't this method of down conversion have its drawbacks, such as in case of a non periodic signal?" you deserve a letter of commendation!
