Carl Sagan came alive as he detailed over 20 specific NASA, ESA, SpaceX and other countries plans that include present and future robotic and manned space missions. Sagan also covered missions to the exotic moons of Jupiter and Saturn plus planets Venus and Mars.
The physics of different wave lengths of light and its effects on our moods,m physiology and surroundings. Covering light polluntion issues.
This presentation is going to highlight the common snook expansion northward in the Gulf, including seasonal habitat use and critical winter thermal refuge habitat. The talk will give the audience a case history of how climate change in impacting the habitat use of native species in Florida, with implications for freshwater flow management in springs and species trophic dynamic relationships.
Forget everything you thought you knew about time. This isn’t a lecture—it’s a journey through quantum weirdness, and the ticking clock in your head. From ancient rhythms to Einstein’s spacetime, from photons that don’t experience time to brains that bend it, we’ll reimagine time not as a backdrop—but as one of the biggest mysteries in the universe. Is time real? Or is it just messing with us?
Do you know how they do it? Justin Davis covered some of the most famous 'hacks', what an ethical hacker does to combat them and how we can all be more vigilant to protect ourselves.
The movement toward healthy food choices has attracted lots of attention and created as much confusion. Backed by nearly 2 years of personal experience, Jerry has examined one clear lifestyle and will share his findings.
An American engineer, Robert McElroy, built a solar-thermal hybrid automobile. Driven by the venerable Stanley Steamer steam system, his invention produced patents to heat and cool and support residential electrical power. His presentation walked through the design and implementation, sharing original photos and schematics.
Steve explored the inner workings of AI (Artificial Intelligence) - programs, core capabilities, trajectory of their advancement. He gave insight into how AI campares to human consciensness and whether it has the potential for true awareness
Len, along with John and Scott, presented research material from the University of Florida. They covered over 250 years of science and experience, clarifying many of the misunderstandings and myths about lightning.
Ron was prepared to make hydrogen and use it to shoot rockets across the room, Recreation Center withdrew permission 10 minutes before his demonstration. Reduced to an 'improv' presentation, Ron gifted us with a 'refresher' or reading the periodic table, the HONC elements (Hydrogen, Oxygen, Nitrogen, Carbon) of of life, and how to prove water is two parts hydrogen and one part oxygen. (He did show electric current from a simple electrolyte + water and the hydrogen emitted from the pole of a fire alarm-type 9volt battery in salt solution.)
Climate data clearly show that all measures of severe weather, including hurricanes, tornadoes, droughts, floods and wildfires are either slowly decreasing, or at least showing no trend at all. Not only is CO2 warming trivial, but there is no proof that man-made CO2 harms our climate. In fact, global warming and increasing CO2 benefit our ecosystems.
We'll discover how stars formed and continue to form. We will look at the sun among the wide variety of stars, and understand how it works. We'll look at the death of stars, including our sun, and see how supernovas made us possible.
The Roman Telescope is scheduled to launch in 2027. What’s its purpose? Who was it named after and what will we learn from it?
Even though there is some truth to them all.... using available evidence, we looked at these many claims including geo-engineering, HAARP, and other conspiracy theories. Some are funny - some are outrageous - and most contain an abundance of sky-is-falling rhetoric. Caution. Do not over-medicate prior to this talk. Numerous natural factors have caused global warming and cooling for billions of years. What is the evidence for the overwhelming scientific consensus that the current extrordinary warming is caused mainly by greenhouse gases released from humans burning fossil fuels? What alternative explanations have been proposed, and are they credible?

Jean, The Beekeeper, is a Villages resident. She presented a short intro to beekeeping and explained the health benefits of a variety of honeys from buckwheat to tupelo.
Focused on the renaissance of commercial nuclear power used for electricity generation, Don explained how nuclear is used to produce electricity, covering current worldwide generation, why expansion slowed, what is reviving planning of new plants, and future challenges
While most were sleeping at 3 AM, it only took the tornado 5 minutes to leave a path of destruction across The Villages. There was no loss of life, but there were numerous injuries as it damaged about 1,300 Villages homes. Learn why February is the worst month for Florida tornadoes and learn why we are in a Doppler Radar dead zone. A checklist of valuable tornado life-saving preparations will also be presented.
The real story on how to increase the absorption of nutrients. Look forward to teaching you a realistic food plan together based upon your lifestyle and health conditions.
A brief history of automotive fuels - their beginnings, strengths, failings and future.
