  Changing Our System Of Land...

  Most people aspire to become property owners and view real estate investments as an important way to build wealth and security. Mortgages are the norm. But does this system truly serve the well-being of either the economy or the individual? Martin Adams shares a view that profiting from land ownership causes social and cultural decline as well as environmental devastation. He introduces a radically new economic model that points to a more fair and abundant reality for everyone. He says this about mortgages, “As long as it remains an ongoing reality for the majority of human beings to have to pay other human beings for the land that they’re standing on, the economic system will forever cause wealth inequality at a core level.” Tune into this dynamic dialogue in order to fully understand his vision of a more equitable economic system that takes banks out of the picture and puts community in the center of economic of wealth and prosperity.

  Anthropocene - A Very Short...

  The proposal that the impact of humanity on the planet has left a distinct footprint, even on the scale of geological time, has recently gained much ground. Global climate change, shifting global cycles of the weather, widespread pollution, radioactive fallout, plastic accumulation, species invasions, the mass extinction of species—these are just some of the many indicators that we will leave a lasting record in rock, the scientific basis for recognizing new time intervals in Earth's history. The Anthropocene, as the proposed new epoch has been named, is regularly in the news. 
   
   
   
  Even with such robust evidence, the proposal to formally recognize our current time as the Anthropocene remains controversial both inside and outside the scholarly world. Instead, the Anthropocene has emerged as a powerful new narrative, a concept through which age-old questions about the meaning of nature and even the nature of humanity are being revisited and radically revised. 
   
   
   
  This Very Short Introduction explains the science behind the Anthropocene and the many proposals about when to mark its beginning: the nuclear tests of the 1950s? The beginnings of agriculture? The origins of humans as a species? The Anthropocene remains a work in progress. Is 
  this the story of an unprecedented planetary disaster? Or of newfound wisdom and redemption?

  Euclid: The Life and Legacy of...

  Of the many mathematical advances made by the Greeks, none rival those established by Euclid of Alexandria, who likely remains the most famous ancient mathematician despite the fact little is actually known about his life. He revolutionized geometry, mathematics, and astronomy in Alexandria, Egypt, around 300 BCE, yet left almost no clues about his life story. Historians know he was a trailblazing mathematician and dabbled in astronomy because he wrote many books on these topics, and a 13-book treatise of his has survived, along with four other books. Thus, it’s clear what Euclid learned and knew, but virtually nothing is known about how his life unfolded or what he was like as a person.  
  	To this day for many students, geometry class was the first time discovering that mathematics is more than calculating numbers. Some may have expected to study shapes, sizes, positions, and the properties of space, but perhaps for the first time, a geometry class required proving why the calculations were true through rigorous, logical arguments using definitions, postulates, and theorems. For countless students, it is excruciating, while others find it fascinating. Either way, the person to thank (or blame) for that is Euclid.  
  	Often called the “Father of Geometry,” Euclid’s influence is so pervasive that his book, The Elements, was the primary math manual for over 2,000 years. It was not a “textbook” in the modern sense, as it did not have problem sets, word problems, or diagrams for practice, but it was a foundational reference and logical guide that students had to read, memorize, and demonstrate. In both the Western and Islamic worlds, Euclid’s Elements was the standard geometry text for almost every educated person until the 19th century.

  Pass the respirator fit test...

  This audiobook is a study guide to prepare for the Respirator Fit Test CNC method exam. It presents more than hundred questions and answers relating to human respiratory system and defence mechanisms, health effects of airborne contaminants, respiratory hazards in the workplace, general respiratory fit testing and respiratory selection requirements, and a sample script to prepare for the submission of a video demonstrating respiratory fit testing by the CNC (Condensation Nuclei Counter) method. 
  Respirator fit testing is a process used to determine whether a particular respiratory protective equipment (RPE) fits an individual properly and provides an adequate seal to protect against hazardous substances. Fit testing is required for tight-fitting respirators, from disposable filtering facepieces to reusable full-face respirators, including some respirators that typically operate in positive pressure mode. 
  There are several methods that can be used for respirator fit testing, including the CNC (Condensation Nuclei Counter) method. The CNC method involves measuring the particulate concentration inside the respirator while the user is wearing it and performing a series of exercises or movements to simulate the physical demands of the job. If the ratio between the air concentration inside the respirator and outside of the respirator meets the respiratory protection standard it is considered to have a good fit. 
  To prepare for the RESP-FIT CNC method exam, this book provides the listener the principles and procedures of respirator fit testing, including the CNC method. This includes excerpts from Australian and International Standards and guidelines and learning about the various types of RPE and their specific fit testing requirements. The listener should also become familiar with the equipment and procedures used in fit testing, as well as the potential risks and limitations of the CNC method.

  The James Webb Space Telescope or JWST was launched on Christmas in 2021 to provide the most sensitive telescopic views of the Universe.It has already revolutionized our real world views of the early Universe and these observations question our current theories of the creation of the Universe.This book gets into the history of the JWST, the instruments it carries, new observations, and ideas of what these anomalies mean.We review some of the most important observations made to date, and finally, some theories of how to explain these incredible views of the early reality of the Universe.There are also some other anomalies in Space which are mentioned which were known before the JWST existed which also question the current Big Bang paradigm.We are living in a revolutionary period of Astronomy much like the questions which occurred to Astronomers and Physicists in the early 20th Century which led to the theories we have today on Universe creation.I’m sure that new paradigms will be the result of the current confusion which will contribute to new theories and better understandings of the world we live in.
