  General Relativity - A...

  General Relativity, formulated by Albert Einstein in 1915, is a theory of gravitation that revolutionized our understanding of space, time, and gravity. Unlike Newton’s theory of gravitation, which treated gravity as a force between masses, General Relativity posits that gravity is a result of the curvature of spacetime caused by the presence of mass and energy. This chapter serves as an introduction to the fundamental principles of General Relativity and the key concepts that underpin this theory. 
  One of the central ideas of General Relativity is the equivalence principle, which asserts that there is no distinguishable difference between acceleration due to gravity and acceleration due to other forces. This insight led Einstein to the realization that gravity could be described not as a force, but as a manifestation of the curvature of spacetime. Spacetime, a four-dimensional continuum, is distorted by mass and energy, and this curvature dictates how objects move within it. Objects follow the “straightest” possible paths, known as geodesics, which are curved in the presence of massive objects. 
  Another cornerstone of General Relativity is the concept of curved spacetime. The presence of mass and energy alters the fabric of spacetime, much like a heavy ball placed on a stretched rubber sheet deforms the sheet’s surface. The more massive an object is, the more it warps spacetime. This warping of spacetime is what we perceive as gravity. For example, the Earth orbits the Sun not because the Sun exerts a force on Earth in the traditional sense, but because the Sun’s mass curves spacetime, and the Earth follows the geodesic path within that curvature.

  Walleye - A Beautiful Fish of...

  Among the more than 34,000 species of fish, few have the walleye's following—among anglers and diners, states conferring official status on the fish, and towns battling for recognition as the Walleye Capital of the World. And among those passionate fans, few know the walleye as well as Paul J. Radomski does—a fisheries biologist, lake ecology scientist, and old fisherman. In Walleye: A Beautiful Fish of the Dark he unspools the mysteries of this fascinating fish. 
   
   
   
  Radomski looks at walleye from every angle, with something to say to the curious naturalist, committed ecologist, and avid fishing enthusiast. People who view walleye as the "lion of the lakes" might be surprised to learn that rivers are their ancestral habitat. Some might wonder about the name "wall-eye," a nod to an evolutionary adaptation to dark water environments. Others might ask: what are they, where do they exist, how do they survive, and how have people come to depend on them? Radomski discusses the principles and pitfalls of managing this predator of the twilight and shares his informed perspective on when and where stocking is prudent. He also explores three of the best walleye lakes. 
   
   
   
  From the simple pleasures of fishing for walleye to the most pressing questions about how this species survives, this book is the best word on this beautiful fish of the dark.

  Multisolving - Creating Systems...

  For most of Elizabeth Sawin's career, she was not a multisolver. Instead, she worked on a single, albeit immensely important problem: climate change. Despite tremendous effort, she felt like she was chasing her tail. Unless people began to recognize the multitude of unexpected benefits from ratcheting down emissions, climate change would remain a losing political issue.That experience, along with the guidance of leaders in systems thinking and racial justice, convinced her that the world's thorniest problems may be easier to tackle together than one by one. That's multisolving: using a single investment of time or money to solve many problems at the same time. Multisolving addresses the current mismatch between complex, deeply intertwined societal issues and our siloed approach to them.This unique resource is for local school boards that need revenue for their students but don't want to overtax low-income seniors. It is for nonprofits working to reduce food waste and combat the root causes of hunger while increasing racial justice. It is for seaside communities that can protect themselves from flooding while also improving biodiversity with a living coastline. It may also be for you: doing the work you know is imperative but that is sometimes overwhelming, a tiny drop in a swirling ocean.

  Recently, I learned about General Artificial Intelligence and the implications it will have in our lives. The array of opinions crosses the full spectrum from the wonderful ways it will improve our lives to the fear it could unleash a ‘Self-Controlled Superintelligence’ that may not align itself with human social and ethical constructs. This subject is fast moving rocket and it is important that everyone understands some key terms when it comes to Artificial Intelligence. Whether you know it or not, AI touches your lives today and in future, will increase exponentially as it exerts this massive influence in our lives. 
  In addition, being a student of Economics and Business, I always seek to refresh my knowledge of key terms in these areas. Economics, Business and Politics overlap a great deal in academia and in real-world applications. Artificial Intelligence will add for the better bringing the fields of Business, Politics and Economics together for the betterment of society. 
  Contained within is a small list of common terms in the areas of Economics, Business and Artificial Intelligence. Political terms are not included here but you will read some definitions of Economics that do have an overlap of political inferences. 
  I hope these terms and definitions provide some insight into the world of economics, business, and artificial intelligence. They all affect your lives more than you realize.
