On Spacetime as a Damped Oscillator and The Dark Universe

Balungi Francis

Sinossi

The universe is full of matter and the attractive force of gravity pulls all matter together.The expansion of the universe has not been slowing due to gravity, as everyone thought, it has been accelerating.Maybe it was a result of a long-discarded version of Einstein's theory of gravity, one that contained what was called a "cosmological constant." Maybe there was some strange kind of energy-fluid that filled space. Maybe there is something wrong with Einstein's theory of gravity and a new theory could include some kind of field that creates this cosmic acceleration.It turns out that roughly 68% of the universe is dark energy. Dark matter makes up about 27%. The rest - everything on Earth, everything ever observed with all of our instruments, all normal matter - adds up to less than 5% of the universe. Come to think of it, maybe it shouldn't be called "normal" matter at all, since it is such a small fraction of the universe.Balungi Francis explains this major conundrum in modern science, modifies General relativity and gives a solution to the cause of an accelearting expansion of the Universe.This book provides solutions to the following major questions In Physics:What is the cause of the observed accelerating expansion of the universe (the de Sitter phase)? Are the observations rightly interpreted as the accelerating expansion of the universe, or are they evidence that the cosmological principle is false?Is the universe homogeneous and isotropic at large enough scales, as claimed by the cosmological principle and assumed by all models that use the Friedmann–Lemaître–Robertson–Walker metric, including the current version of the ΛCDM model, or is the universe inhomogeneous or anisotropic?Is the Friedmann–Lemaître–Robertson–Walker metric the right metric to use for our universe?Why does the zero-point energy of the vacuum not cause a large cosmological constant? What cancels it out?Is dark energy a pure cosmological constant or are models of quintessence such as phantom energy applicable?Not since  James Clerk Maxwell celebrated best-seller a Dynamical Theory of the Electromagnetic Field and  Carlo Rovelli  Reality Is Not What It Seems: The Journey to Quantum Gravity  has physics been so vividly, intelligently, mathematically  and entertainingly revealed. This is a First Edition to the study of spacetime and dark energy .

Mighty Bad Land - A Perilous...

Bruce Luyendyk, Edward J. Larson

What does it take to prevail in Antarctica? 
 
 
 
Four geologists and two mountain guides face the brutal beauty of West Antarctica eight hundred miles from the United States main base. Their search reaches far into the treacherous mountains of Marie Byrd Land. Over six weeks of living in tents and traveling by snowmobile, the team endures endless cold and furious blizzards. They cross ice fields and hidden crevasses, which one of the team learns about the hard way. 
 
 
 
What keeps them going in spite of these dangers? Will the mountains give up their secrets? Can these scientists find evidence of the formation of the ranges many millions of years ago as the giant continent of Gondwana began to break apart? Was a new continent, now known as Zealandia, created by this event? 
 
 
 
Mighty Bad Land, told firsthand by Bruce Luyendyk, a former professor of geology, reveals his inner battles and challenges: he's almost fifty, asthmatic, and fights chronic pain. Through deft storytelling, listeners are invited into a land of emptiness, beauty, constant daylight, and unseen menace.

The Great Dead Body Teachers

Jackie Dent

An adventure into the world of anatomy and dissection. 
Since I was a child, I’ve been interested in dead bodies. When I was eight years old, I dug up the remains of my pet budgie Zazbut. He had been buried for about eight weeks in a patch of grass outside our house in Dasmarinas, a fortified village in Manila, in the Philippines. 
 
‘The first exhumation was the beginning of my intrigue with death, which has persisted. As a journalist, I’ve written about graveyards, funerals and death doulas. I always visit the local cemetery wherever I am in the world. But one thing that has largely been hidden from me in this death trip is the dead body. 
 
Dissection might not be a normal topic to contemplate but when both your paternal grandparents donate their bodies to science it does intermittently cross your mind. 
 
This is the story of how Jackie Dent’s grandparents - Ruby and Julie - gave their bodies to science when they died. No one in her family seems to know why, or what really happened with their bodies afterwards. Were they avid science buffs? Was it to save on cremation costs? How do scientists tackle the practicalities and ethics of cutting up the dead for research? And who are body donors generally? 
  
Weaving the personal with the history of anatomy and the dissected, Jackie Dent explores the world of whole-body donation — all the while looking for answers as to what happened to her grandparents.

Cannabis in the Treatment of...

Pharmacology University

Welcome to explore this wonderful audiobook in which you will learn about the benefits of cannabis sativa as a treatment for anxiety.
At the beginning you will surely have some doubts such as: what is anxiety? How do I know if I suffer from it? Read it with us and find out.
Anxiety disorder is a collection of mental health conditions, characterized by ambiguous situations, by a disproportionate concern about future events that provoke physiological and behavioral responses, which prepare the individual for defense or flight.
Worldwide, the estimated number of people with anxiety disorders totaled 264 million in 2015, a consequence of population growth and aging. In the Americas Region, it is estimated that up to 7.7% of the female population suffers from anxiety disorders (3.6% of men). Therefore, there is a greater need to address new therapeutic alternatives such as medical cannabis for the management and control of these conditions and to improve the quality of life of those who suffer from them.
In this audiobook, you will understand how molecules derived from the cannabis plant, known as cannabinoids, could be indicated for the effective treatment of patients diagnosed with this disorder. For this it is important to know the evolutionary history of anxiety, epidemiology, risk factors and how the diagnosis is made, the endocannabinoid system and its distribution in the body, its receptors and all the wonderful homeostatic-physiological functions it performs in our central nervous system, as well as clinical studies showing that phytocannabinoids, especially CBD, works as a possible anxiolytic treatment, for a satisfactory clinical evolution.
Learn more about the incredible medical cannabis and how it can improve the quality of life of those suffering from anxiety disorder. We invite you to enjoy this audiobook that Pharmacology University brings to you.
