  • How to Live Much Longer

    The Mitochondrial DNA Connection

    Series series Biomedical and Life Sciences (R0)
    This book is about why we age and how to fix it. Human aging, a complex biological process, has long eluded a unified explanation. The book explains that aging is fundamentally a cellular energy crisis, driven by the progressive accumulation of damage to the vulnerable DNA of mitochondria, the cell's primary energy producers. Drawing on this perspective, which emphasizes energy conservation and ... Read more

  • A Brief History of Physical Science

    by John Cramer ...
    Why do we think matter is made of atoms and the Earth goes around the Sun? How big is the universe? Did it have a beginning or is it eternal? Is heat a fluid or just the random motion of molecules? Is light made of particles or is it a fluid or maybe something else? This book answers these questions and many more as it traces the development of the modern scientific understanding of the physical ... Read more

  • How Alien Would Aliens Be?

    by John Cramer ...
    How alien would aliens be? Would they look like us or perhaps more like an octopus? How would they communicate? Could we even hear their voices, assuming they have them? Like us, aliens would be constrained by the physical world. Understanding how those physical constraints apply both to us and to aliens is the theme of this book. The constraints imply that they will not be all that different from ... Read more

  • The Quantum Handshake

    Entanglement, Nonlocality and Transactions

    Series series Physics and Astronomy (R0)
    This book shines bright light into the dim recesses of quantum theory, where the mysteries of entanglement, nonlocality, and wave collapse have motivated some to conjure up multiple universes, and others to adopt a "shut up and calculate" mentality. After an extensive and accessible introduction to quantum mechanics and its history, the author turns attention to his transactional model. Using a ... Read more

  • Solving Diophantine Problems

    by John Cramer ...
    Diophantine problems are word problems that essentially set up algebraic equations to be solved for positive integer or at least rational solutions. They are typically under-determined which opens up the possibility, if not the likelihood, of multiple solutions. This under-determined nature lends an air of mystery to them that adds to their fascination. Solving them seems magical because one ... Read more

  • Your Choice of World

    by John Cramer ...
    In case you haven't noticed, you get to choose the world you live in. I don't mean you can control the conditions of your life.
