This book (a collection of related articles from one of the sci-fi magazines of the mid 40's) describes the world of the future before the transistor was invented (so the new technology is based on vacuum tubes!) This book is a refreshing and delightful look at life and invention on board a space station. From the manager of the local eating establishment (who gets annoyed when the engineers keep taking his tablecloths to the drafting department to document their designs) to the engineer who discovers how to move matter from point A to point B by transmitting it through the ether (and has a slight problem demonstrating this with a patent judge's antique pocket watch), engineers will especially enjoy this refreshing look at what the future could have been.
