I studied under C J Rallis (thermodynamics). He was an extraordinary man and my only regrets was that I did not spend enough time with him. He was born in Mozambique and taught at the University of the Witwatersrand for many years. He was the only engineer that had a Thermodynamic Cycle named after him since the 19th century. I could write a book about my experiences with him and how we finally produced an engine that had only one moving part! >My past is disappearing, often without my even knowing it existed. This reminds me of a friend that is fond of saying we are becoming ... yesterday's people! Luckily with the internet now we may leave something behind us that future generations may or may not find interesting:)
