The Biggest Questions: What Is Time? Profesor Julian barboiur in discussion with Tony Sobrado

This is taken from Tony Sobrado's Biggest Questions Podcast series

Listin to the full discussion here:

Time, its passing, its measurement and its experience is fundamental to our understanding of existence with regards to both the cosmos and the cognition possessed by our species. Without it, change, order, duration and concepts such as beginning and end would not be possible to conceive of let alone value. But what is time and how does it exist? Welcome to the bizarre world of time where philosophers and physicists comprehend time in a way that is almost completely divorced from our everyday intuitions of time. According to Einstein's Theory of Relativity there is no universal simultaneity; all time is relative and thus the past, present and future may all already be existing at once. Others perceive time as an illusion; and when we get down to the quantum level things do not get any clearer.

Julian Barbour is visiting Professor of Physics at the University of Oxford and author of The End of Time and The Discovery of Dynamics. In this fascinating discussion Barbour explains how the measuring and perception of time arises due to shape dynamics and their configurations.

Building the World's Greatest Swing Set | Part 1

Part 2:
This wooden swing set is epic, it has everything, tub slide, monkey bars, a bridge, multiple levels and swings. This is not a complicated swing set to build but it does have a lot of parts. Build time for this wooden playset was roughly 30 hrs but would be less now that I have ironed out the issues in the original plans. Cost for everything, slides, swings and lumber included was $2300...cost will vary based on lumber cost in your areas.

I have put together 44 pages of colored, highly detailed, step by step plans that have all the parts and supplies that you will need to build this swing set for your children

Plans to show how to build one for yourself!

Researchers tested how feeding cougars reacted to recordings of human voices, including Rachel Maddow and Rush Limbaugh. While recordings of frogs elicited no flight response, the cougars frantically escaped as soon as the human voices were played. This could have important effects on predator-prey relationships. Habitat loss and fragmentation is rising, which leads to decreased feeding time as more people cross their paths. After hearing humans, cougars reduced their feeding time on kills by about half. This causes a 36% increase in their kill rates in areas with high human activity, which further increases the chance of encountering humans.
