“This wonderful book is full of such insights, reflections, analyses, appraisals, and even anecdotes, and should be a smash hit: we should all seek to know more about these foundations, and we have a wonderful set of essays here, based off Hilbert’s original wonderful lectures, and a lot more.” (Michael Berg, MAA Reviews, July, 2018)“The book provides innovative ways of thinking about the linkage between planning and environmental issues. I recommend this book to all researchers, policymakers, and planning practitioners engaged in searching for effective solutions for future sustainable urban and rural development.” (Eduardo Oliveira, Journal of Urban Affairs, Vol. 40 (6), December, 2017)
