Imagine this could you craft your very own radio set from scratch? Before you rush to answer, consider this carefully. We‚Are not asking if you can assemble a set from pre-made parts; were challenging you to create every single component yourself‚Aîfrom the ground up. This means fabricating vacuum tubes, generating the acid for batteries, and even weaving the wires and insulation. Now, envision yourself as the protagonist in a gripping tale‚Aîstranded among intelligent savages in a primitive world. With only your scientific knowledge to guide you, and no tools other than those you fashioned yourself, could you, under dire circumstances, build that radio set? ‚AîR. M. F., 1926. (Foreword)
