Visualizing Einstein's Special and General Relativity"

     Ira Glickstein    22 Jun 2015        Reference Site    

While we all recognize the importance of Einstein's Theories of Special (1905) and General (1915) Relativity, for Ira Glickstein, as an engineer, the complex math leaves him cold and frustrated by an inability to 'visualize' the 'slowing down of Time' and the 'contraction of Space' that occurs at high velocity and/or high acceleration.   Having wrestled with these theories this pas year, he has developed an interesting (perhaps unique) way to visualize 'Relativistic' effects and their (perhaps surprising) consequences.  Dive deeper into his concepts and perspectives at his website:  http://visualira.blogspot.com/

    Michael Richardson    8 Jun 2015   Part 1 early history pdf      27 Jul 2015   Part 2 storied history pdf 

Astronomy is the oldest of the natural sciences, dating back to antiquity, with its origins in the religious, mythological, cosmological, and astrological beliefs. Ancient astronomers, like Aristotle, were able to differentiate between stars and planets, as stars remain relatively fixed over the centuries while planets move an appreciable amount during a comparatively short time, but it was not until the 16th and 17th centuries that the first to attempt to derive mathematical predictions of celestial phenomena in astronomy. Part 1 looks at the earliest history. Part 2 follows a progression of 'interesting stories' that comprise the science of astronomy through time.

"Broadcast Digital TV Reception:  a technical perspective"

     
Steve Martin    25 May 2015       view pdf    


Broadcast digital television offers many advantages over the old analog broadcasts, including high definition pictures, Dolby 5.1 surround sound, multiple language tracks, and a huge increase in the number of available channels.  Technical differences between digital and analog broadcasts, along with marketing hype, can cause confusion over what is needed to receive over-the-air television signals.


Steve explains the results of his home-base laboratory investigation:  implementing digital TV reception in the Villages, sans cable.  He discusses antenna selection, amplifiers, channels and signal strengths.  Very practical.  Extremely informative.

"Technical Ideas for the Origin of Life"

     
Phil Geis    27 Apr 2015       view pdf    


Most Science estimates life on Earth began about 3-4 billion years ago.  Working backward under the theory of evolution, an understanding of past and current life form progression, continues to be established.  However, no theory has been accepted for the beginning of life, a concept that itself has no easy definition.


Creation or initiation of life on Earth is an unimaginably improbable phenomenon that occurred at least once and has not been observed since.  I will discuss concepts that inquire at the edges of life's beginnings, none of which has risen to the level of scientific theory.


"What Makes Us Human"

     
Lee Conrad    13 Apr 2015       view pdf     


Comprehending that the Earth's evolution began 4 billion years ago is difficult for most.  Presented within the context of a 24-hour day, Lee Conrad clearly presents an understanding of evolutionary time.  His presentation discusses: 

  •     The conventional view of the Origin of our Genus, Homo
  •     How going hairless had profound consequences on subsequent phases of evolution
  •     The iconic molecule called DNA
  •     The importance of the Human Genome to expressing our many evolutionary traits ( eye color, height, weight, build structure, etc )
  •     Tracking the origins of modern Humans from Africa to the Americas 
  •     Alphanumeric genetic markers that express patterns occurring in Mitochondrial DNA to Y-Chromosomes to the whole genome  

Lee Conrad looks specifically at the distinctive DNAs.  Discovery of the 1st distinctive DNA to humans,  HAR1 (Human Accelerated Region 1) played a role in the developing of cerebral cortex.  Five other distinctive DNAs  (FOXP2, AMY1, ASPM, LCT, HAR2) are functionally examined, along with the rate of change over tens of thousand of years:  the painfully slow process of natural selection. 


"Alan Turing's Wonderful Machine"

    
Dan Sullivan    23 Mar 2015       view pdf    


The popular movie, The Imitation Game, tells the story about how Alan turing invented a machine that decoded German military messages in World War II.  Turing is credited with cutting two years off of the war by doing this.


But before that, in 1937, he published a paper in Proceedings of the London Mathematical Society about the kind of numbers people could compute.  To prove what he claimed in this paper, he invented a different machine:  a computing machine which later became known as a Turing computer.  The title of the paper was "On Computable Numbers with an Application to the Entscheidungsproblem". Though this paper was about mathematics, it is the foundation of just about everything we know today as Computer Science and the Theory of Computation.


Dan Sullivan presents the paper in a clear and understandable format.  He covers what a computing machine is, the incredible insight Turing had into the automatic computation of numbers, and what we commonly refer to today as 'computing'.  The talk covers the mathematic problems Turing solved, and at least for some of them, how Turing solved them.  He shows how a Turing machine works and how it relates to computers today.

Entanglement and Other Quantum Weirdness

     Bob Miller    23 Jun 2014


Quantum mechanics is a highly successful theory that nonetheless contains many strange, non-intuitive, and difficult to imagine aspects that still puzzle the experts. The theory has explained the physical nature of chemistry. It provides the understanding of semiconductor devices that are the basis of the growth of digital electronics. It has explained many phenomena in atomic theory and particle physics. Besides entanglement, we will look at the wave-particle duality, uncertainty, the exclusion principle, tunneling and the elusive meaning of the wave function.


A Virtualized Artificial Pancreas System for Type 2 Diabetes

     Michael Albisser    9 Jun 2014


Type 2 diabetes is 20 times more prevalent than Type 1 and leads to diabetes-related complications sooner. In addition to islet cell transplantation, major initiatives to create an artificial pancreas system for the Type 1 subgroup are in progress. By comparison options are limited for the Type 2 population.Preliminary experience with a novel, virtualized artificial pancreas system for Type 2 suggests that patients referred by their doctors can learn 1) why a goal of optimal diabetes control is important and, 2) how to use this system to help achieve and then maintain this otherwise elusive goal.The presentation will describe the technical and scientific novelties of the artificial pancreas system for Type 2 diabetes and illustrate its efficacy in exemplary cases of advanced diabetes. A Pamphlet will be provided that describes the 3 Support Group Sessions available for the 30,000 with Type 2 diabetes right here in The Villages.


Lascaux Cave Painting Preservation

     Phil Geis   26 May 2014


Lascaux is one of the world's treasures - cave paintings of bison, antelopes and other animals, some huge. In a testament to ancient artistry, the painted animals appear to lunge and gallop in the flickering light of torches as their prehistoric painters must have used. Discovered just after the second world war, human presence and modifications exposed the cave and its paintings to insects, flooding and molds, the last of which most immediately threatens the paintings. Efforts to preserve the cave and its art have been burdened with bad science, big ego and politics both French and with the UN. This discussion will trace the modern history of the cave Lascaux and its paintings, the attempts, many now seen as foolish, to preserve the cave and its art and the current efforts with their technical and political realities.

Optimal Span

    Ira Glickstein  10 Feb 2014


Optimal Span - The Amazing Intersection of Information Theory, Hierarchy Theory, and Complexity Theory" (AKA "The magical number 7 +/- 2"). It turns out that such diverse-seeming structures as RNA (Biology), Sensory Span of Absolute Judgement (Psychology), Management Span of Control (Human Organization), and Written Language (Literature) ALL have a common Optimal Span in the range of five to nine. Indeed, it appears that ALL competitively-selected structures, such as those that have come about due to Darwinian Evolution and Natural Selection of Genes, follow the dictates of Optimal Span. And this commonality extends to the Scientific and Technological creations of Human Brains.
