In 60 Seconds You Will Realize that Time is Real
Everything we experience and know about is caught in time, is caught in a moment, is not an illusion.
By "time is real" I mean to say that everything we experience and know about is caught in time, is caught in a moment, is not an illusion. It’s the deepest clue we have, perhaps, to the nature of reality.
This is to counterpose the picture which was developed in physics from Galileo and Newton and Descartes down to the present quantum cosmologists: that time is an illusion, time is an auxiliary; that reality is behind this veil of illusion, is timeless, is permanent, is outside of time. As Einstein and many other people have said, our experience of the distinction between past, present and future is an illusion and reality is just the whole history of the world at once.

What can 3D printing do for medicine? The "sky is the limit," says Northwell Health researcher Dr. Todd Goldstein.
- Medical professionals are currently using 3D printers to create prosthetics and patient-specific organ models that doctors can use to prepare for surgery.
- Eventually, scientists hope to print patient-specific organs that can be transplanted safely into the human body.
- Northwell Health, New York State's largest health care provider, is pioneering 3D printing in medicine in three key ways.
- "I consider that a man's brain originally is like a little empty attic, and you have to stock it with such furniture as you choose," Sherlock Holmes famously remarked.
- In this lesson, Maria Konnikova, author of Mastermind: How to think like Sherlock Holmes, teaches you how to optimize memory, Holmes style.
- The goal is to expand one's limited "brain attic," so that what used to be a small space can suddenly become much larger because we are using the space more efficiently.
The controversial herbicide is everywhere, apparently.
- U.S. PIRG tested 20 beers and wines, including organics, and found Roundup's active ingredient in almost all of them.
- A jury on August 2018 awarded a non-Hodgkin's lymphoma victim $289 million in Roundup damages.
- Bayer/Monsanto says Roundup is totally safe. Others disagree.
- Our ability to behave rationally depends not just on our ability to use the facts, but on our ability to give those facts meaning. To be rational, we need both facts and feelings. We need to be subjective.
- In this lesson, risk communication expert David Ropeik teaches you how human rationality influences our perception of risk.
- By the end of it, you'll understand the pitfalls of your subjective risk perception system so that you can avoid these traps in the future.
