The Hidden Half of Nature: The Microbial Roots of Life and Health by David R. Montgomery and Anne Bikle

A geologist and a biologist buy a house with fixer-upper dirt and learn how to make it fertile. They added tons of coffee grounds, wood chips, leaves, and home-brewed compost tea and it worked over a period of several years. " nurturing the microbial life below ground, we can reverse much of the damage caused by the ancient practice of plowing and the modern overuse of pesticides and fertilizers. Microbes maintain our health too.

The Hidden Life of Trees by Peter Wohlleben

The subtitle is What They Fell, How They Communicate, Discoveries from a Secret World. Trees lives longer and do things at a slower pace. The send slow electrical signals and release chemicals that other trees can detect. The are social and care for each other by means of soil fungi. Isolated trees live shorter lives than those living connected together in forests.

Now: The Physics of Time by Richard A. Muller

As the Big Bang creates new space, it also creates new time ... and that new time is the key to now.
At least some random element originated in quantum physics so physics is incomplete implying free will is possible.

He explores the limitations of physics. "What does the color blue look like?", for example. "the evidence leads to the conclusion that physics is incomplete, that it will never be capable of describing all of reality."

Beyond Culture by Edward T. Hall

It's fascinating how much we are influenced by out culture. Chapter 6, Context and Meaning, defines a high-context communication in which most of the information is in the physical context or internalized in the person, while very little is in the explicit coded part of the message. In a low-context communication the mass of information is vested in the explicit code. Cultures tend to emphasize one or the other which makes communication difficult between them, if different.

Chapter 10 covers action chains. An action chain is a set sequence of events in which usually two or more individuals participate. He gives an example of college students courting behavior as shown in the library.

A Language Older Than Words by Derrick Jensen

The insight here is that humans should feel part of the world and respect the plants, animals and stuff in our shared endeavor. Even science he says assumes we are trying to conquer nature and make it work for us. Smithsonian magazine had an article about trees communicating in a forest so we have barely scratched the surface of reality.

Ubiquity: Why Catastrophes Happen by Mark Buchanan

     Build a sand pile grain by grain. At some point one grain will cause others to fall. At first only a few fall but overtime one grain can cause all manner of avalanches, big or small, depending on the history of the sand pile and its current structure. There can be a critical state where one grain causes a big effect but there si no big cause just a grain dropping in the wrong place.
     The author illustrates with examples from earthquake prediction, forest fires, evolution, historical events and more. Trying to predict big earthquakes or historical crises may not be possible. Extinctions may not have great causes but may be just the result of an event at the wrong place in the historical flow.

Breathe: The Simple Revolutionary 14-Day Program to Improve Your Mental and Physical Health by Belisa Vranich

Proper breathing is essential for good health. It really does make a difference in ones physical and mental health. She recommends full breaths from the diaphragm so that the stomach expands and contracts not the shoulders. The books goes into details with analyses and exercises.

I just heard a lecture on mindfulness and regarding breathing, the slower animals breathe the longer they live. The author recommends longer deeper breaths so she is on to something. (Added 6-4-18)

The Brain's Way of Healing by Norman Doidge

Doidge gives fascinating insights regarding the neuroplasticity of the brain.

Chapter 1 reports on a case study of a doctor who had an accident that caused intense pain, but he found that the brain can eliminate pain. If you don't move your brain rewards you because pain is a danger signal and there is no danger when you don't move.  The use of much morphine prevented his nerves from becoming chronically stimulated and saved hi from developing a chronic pain syndrome.

The brain controls how much pain we feel. When neurons in our pain maps get damaged they fire false alarms that make us feel the pain is in our body. A chronic injury can cause pain maps to expand so we feel pain over a larger area. Pain can expand to adjacent brain maps causing us to feel pain over a larger area of the body. Chronic pain is a more top-down process.

The same brain areas that process pain also perform other functions. If we can perform those other functions the brain won't process pain. Brain maps are dynamic allocating space according to use it or lose it.  Moskowitz used visual activity to overpower the pain. He asked patients to imagine that the are of the brain devoted to processing pain was shrinking. He never let a pain spike occur with doing some visualization. It takes time but by six weeks his pain was almost gone. It took a year for him to be almost always pain free. He formulated the MIRROR principle for patients to organize their minds: Motivation, Intention, Relentlessness, Reliability, Opportunity, and Restoration. Patients got pain reduction when they stretched or compressed fingers and a camera magnified the effect.

Chapter 2 tells about a man who overcame the symptoms of Parkinson's disease with an exercise program he devised and a special kind of concentration.  Exercise, fast walking, is effective and reduces the risk of dementia.

Chapter 3 covers the stages of neuroplastic healing and the how and why it works.
The Pervasiveness of Learned Nonuse
       Put the good arm in a cast otherwise it will take over the functions of the weak arm whcih will 
       get weaker.
The Noisy Brain and Brain Dysrhythmias
        Turning off the sympathetic nervous system improves the signal-to-noise ratio in brain circuits.

Chapter 4  Rewiring the Brain with Light
Chapter 5 Moshe Feldenkrais ... Healing serious brain problems through mental awareness of movement.
       The brain cannot think without motor functions. Emotions show.  Awareness of movement is key to improving movement. Differentiation -- making the smallest possible sensory distinctions between movements -- builds brain maps. When a body part is injured its representation in the brain map becomes smaller or disappears.  If the stimulus is small then we can detect very small changes.  Slowness of movement  is the key to awareness and awareness if the key to learning.  Reduce the effort whenever possible. Errors cannot be avoided. Let your nervous system decide how to do the movement. Random movements provide variation that leads to developmental breakthroughs.

Chapter 6 A Blind Man Learns to See
     William Bates did for vision what Feldenkrais did for movement. He showed that the habitual ways eyes move affect the eyesight. Eye muscles change the shape of the eye allowing change of focus. Movement of the eye is essential to vision.

Chapter 7 A Device That Resets the Brain
     The device fit into a shirt pocket. The part that goes into the mouth looks like a stick of chewing gum and rests on the tongue. It has 144 electrodes to turn on the tongue's sensory neurons. When it stimulates the neuroplastic brain it modifies and corrects how the neurons are firing. A singer who had lost his voice to 30 years of MS got it back withing a week.  The tongue is one of the most sensitive organs and tongue stimulation activates the whole brain. The team invents exercises to help a person to regain whatever function was lost. The device treats many brain conditions.Yuri believes that the device works by triggering the brain's self-correcting, self-regulating system that allows it to achieve homeostasis. There are no side effects.

Chapter 8 A Bridge of Sound
     Singers were singing themselves into deafness; they sang poorly because they heard poorly. If hearing is fixed it can heal the voice. People with good listening skills mostly speak with the right side of the mouth. Most professional singers are right-eared.

Tresspassing on Einstein's Lawn by Amanda Gefter

  This book is a well-written, fascinating treatment of the lastest results in physics and cosmology in the context of the author's quest to understanding nothingness. Below is an inperfect summary for me to recall what I read.
Asking a yes or no question gets a bit of information. John Wheeler suspected that the universe is built up bit by bit by these measurements. Ours is a participatory universe. Wheeler like to say that the universe is a self-excited circuit, and that the boundary of the boundary is zero.
Wheeler "believed that the universe was right for observers because, somehow, observers create the universe." In special relativity the Lorenz transformation moves one path to another so that you are both loooking at the same world whatever your reference system (in unifom motion). With accelerated motion the parth through spacetime is curved. To match it up with a straight line path you need to curve space. "The wrinkles are gravity." "An inertial frame with a gravitational field is indistinguishable from an accelerated frame without a gravitational field."
Guth said, "...Today we think that the universe has zero values for all conserved quantities." Gravity has a negative contribution to the total energy. It always attracts and it takes energy to separate. It takes energy to bring electric charges together. Guth also said "Everything we see is in some sense nothing." Hawking said that we need to work from the top down, from the present to the past. We create the history of the universe.
"Something is real only if it's invariant." The same in every reference frame.  "..all the forces arise in essentially the same way--specifically, to account for the fact that things appear differently in different reference frames." An electron is described by a wave function which has a phase. If you step to the left you change the phase. The phases don't line up because you can't change it everywhere so you have to bend things which is electromagnetism which is a gauge force.  To "keep all reference frames on equal footing, you need a gauge force.
Chapter 7, Carving the World into Pieces, has much in it, and is too hard to adequately summarize. Gefter talks about the arrow of time and entropy which is a measure of hidden information. Temperature and pressure are shorthand for the detailed information about a gas. An individual molecule doesn't have a temperature. Gravitational entropy points in the opposite direction. It clumps stuff. Gravity is interesting at a black hole. The area of an event horizon can never decrease which resembles the second law of thermodynamics. Bekenstein claimed an event horizon's area is entropy. Hawking showed that black holes do radiate. The event horizon restructures the vacuum. It restricts the wavelengths of zero-point energy that can fit, spawning particles that wouldn't otherwise be there. The particles of Hawking radiation are observer-dependent. An accelerated observer sees a Rindler horizon which is like the event horizon of a black hole. Gravity and acceleration are equivalent. If space expands you get a deSitter event horizon, so we are surrounded by an event horizon. We each have our own universe.
The idea that the total amount of information in any region of three-dimensional space scales with the area of the two-dimensional boundary is called the holographic principle. Two descriptions--inside and outside the horizon--are complementary. The location of a bit becomes observer-dependent when gravity becomes important. Spacetime is no longer invariant.
Geometry, spacetime, doesn't fluctuate.
There isn't a single reality that all observers share. Wave-function collapse is observer-dependent. Interference in the two-slit experiment refers to a comparison between what is observed by one observer and what would be observed by another observer, a comparison between two different frames. If reality weren't observer dependent we wouldn't see interference. Interference cancels out the disagreements between our perspectives.
Light uses up its entire spacetime quotient on space, leaving none for time. It sees all of space in no time. Light is everywhere in a single instant. A photon sees a singularity. Horizons don't have horizons. The boundary of the boundary is zero. Eleven points in Chapter 15 summarize her results. The universe is nothing. If it were something it wouldn't be described by quantum mechanics.You need a broken symmetry to have information and information gives rise to the world. It from bit.
