The Future of Currency
The Lost World of the Kalahari
Laurens’ stirring account of his mid-century exploration of the Kalahari Desert in search of the mythical San peoples.
The Night of the New Moon
Laurens’ deeply moving account of his time in a Japanese concentration camp. A valuable alternate perspective on events culminating in the August 6th, 1945 dropping of ‘Little Boy’ on Hiroshima.
The Nature of Technology
Ambitiously, this book promises to offer a cohesive model for technological progression. Instead, we find a repetitive miss-mash of ill-defined concepts, knotted together through liberal usage of clichéd analogies – “technology is like language”, “technology is like Darwinian evolution”, etc., etc. Highly disappointing.
