Explore the biggest question of all. How far do the stars stretch out into space? And what's beyond them? In modern times, we built giant telescopes that have allowed us to cast our gaze deep into the universe. Astronomers have been able to look back to near the time of its birth. They've reconstructed the course of cosmic history in astonishing detail. From intensive computer modeling, and myriad close observations, they've uncovered important clues to its ongoing evolution. Many now conclude that what we can see, the stars and galaxies that stretch out to the limits of our vision, represent only a small fraction of all there is. Does the universe go on forever? Where do we fit within it? And how would the great thinkers have wrapped their brains around the far-out ideas on today's cutting edge? For those who find infinity hard to grasp, even troubling, you're not alone. It's a concept that has long tormented even the best minds. Over two thousand years ago, the Greek mathematician Pythagoras and his followers saw numerical relationships as the key to understanding the world around them. But in their investigation of geometric shapes, they discovered that some important ratios could not be expressed in simple numbers. Take the circumference of a circle to its diameter, called Pi. Computer scientists recently calculated Pi to 5 trillion digits, confirming what the Greeks learned: there are no repeating patterns and no ending in sight. The discovery of the so-called irrational numbers like Pi was so disturbing, legend has it, that one member of the Pythagorian cult, Hippassus, was drowned at sea for divulging their existence. A century later, the philosopher Zeno brought infinity into the open with a series of paradoxes: situations that are true, but strongly counter-intuitive. In this modern update of one of Zeno's paradoxes, say you have arrived at an intersection. But you are only allowed to cross the street in increments of half the distance to the other side. So to cross this finite distance, you must take an infinite number of steps. In math today, it's a given that you can subdivide any length an infinite number of times, or find an infinity of points along a line. What made the idea of infinity so troubling to the Greeks is that it clashed with their goal of using numbers to explain the workings of the real world. To the philosopher Aristotle, a century after Zeno, infinity evoked the formless chaos from which the world was thought to have emerged: a primordial state with no natural laws or limits, devoid of all form and content. But if the universe is finite, what would happen if a warrior traveled to the edge and tossed a spear? Where would it go? It would not fly off on an infinite journey, Aristotle said. Rather, it would join the motion of the stars in a crystalline sphere that encircled the Earth. To preserve the idea of a limited universe, Aristotle would craft an historic distinction. On the one hand, Aristotle pointed to the irrational numbers such as Pi. Each new calculation results in an additional digit, but the final, final number in the string can never be specified. So Aristotle called it "potentially" infinite. Then there's the "actually infinite," like the total number of points or subdivisions along a line. It's literally uncountable. Aristotle reserved the status of "actually infinite" for the so-called "prime mover" that created the world and is beyond our capacity to understand. This became the basis for what's called the Cosmological, or First Cause, argument for the existence of God. #universedocumentary #spacedocumentary #Universe
Exploration of the solar system began when early sky gazers looked up and saw planets in the sky. At first, they considered them deities, but that changed as people began using science to understand the planets.Today, astronomers use spacecraft and ground-based observatories to make discoveries in the solar system that would leave our ancestors' jaws dropping. Let's see what they've found. What are Planets? The solar system has four rocky planets (Mercury, Venus, Earth, and Mars), two gas giants (Jupiter and Saturn), two ice giants (Uranus and Neptune), and at least half a dozen confirmed or suspected dwarf planets. Pluto is the largest and most famous of them and was explored by the New Horizons mission in 2015. We say "at least" because, by some estimates many more small worlds that orbit the Sun just as other planets do. Most are beyond the orbit of Neptune, except for Ceres, which is the only dwarf in the inner solar system. The idea of "planet" has changed radically from the days of the ancients. Astronomers and planetary scientists are debating just what defines a planet, and the current "official" definition from the International Astronomical Union is not accepted by all scientists. The debate on what "planet" means continues as planetary scientists find more worlds in our solar system #Universe #Space #Documentary

Small Business + AFRL THINK! Event - July 12, 2018
Opening Remarks from
Doolittle Institute Director Carolyn Fries

Ryan Helbach. Ryan Helbach, Chief Intrapreneur
at AFRL, will discuss Innovation and Commercialization
opportunities within AFRL.
Northwest Florida Forward Region Brief on Entrepreneurial
Accelerator & Incubator Efforts.
Accelerators and Incubators are fancy words for
players in the entrepreneurial landscape. Accelerators
support early-stage, growth-driven companies
through education, mentorship, and financing.
Startups enter accelerators for a fixed-period of
time, and as part of a cohort of companies. Incubators
are organizations geared toward speeding up
the growth and success of startup and early stage
companies. They’re often a good path to capital
from angel investors, state governments, economic-development
coalitions and other investors.
