Time may be the least-understood concept modern physics encounters on a daily basis, but we probably hold more pieces of the puzzle than we think. Surprising experimental results and tantalizing theories abound in fields where time is part of the investigations. What has generally been lacking are attempts to assemble these into better models of time and put them into plain language. This text attempts to formulate an intuitively satisfying theory of time based on some of these results. It brings together the philosophical concept of holons (with a four dimensional twist), the 'subjective observations' or Qbist interpretations of quantum mechanics, and the idea that taken together these allow an intuitively satisfying understanding of how the laws of quantum mechanics express themselves at macroscopic scales. Various phenomena that are perplexing from a Newtonian worldview can be explained by this model. This book explores psychological flow, agency, and prayer, encompassing all previously published work on the subject. .

Throughout history complex, open-ended professions have been used as the basis of traditions for self-development. Architecture, alchemy, swordsmanship and carpentry have all at various times served as metaphors and schools for improving oneself through daily practice. Once the open-ended nature of such a skillset is recognised, any practise of the skill becomes a practise for better living. This book asks whether programming may be the next profession to join this list. Drawing on various great thinkers from our age and others, it examines how programming affects us and what it can teach us about our work, our selves, and our future.

With the cost of energy rising and environmental concerns becoming ever more mainstream, many homeowners and contractors are seeking to offset the energy cost of their homes or outbuildings in ecologically-friendly ways. The Walton Solar Thermal kit describes one means of achieving this goal. It provides complete information on how to build and install a solar thermal system that can offset a significant fraction of a building's heating costs using sunlight. This manual presents the three parts of a solar thermal system - the collector, the mechanical system, and the control system - and lays out straightforward, field-tested instructions on how to set up and install each of these in either a new building or a retrofit.
