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. 

In 60 Seconds You Will Realize that Time is Real

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.

CT scans of shark intestines find Nikola Tesla’s one-way valve

Evolution proves to be just about as ingenious as Nikola Tesla

Surprising Science
  • For the first time, scientists developed 3D scans of shark intestines to learn how they digest what they eat.
  • The scans reveal an intestinal structure that looks awfully familiar — it looks like a Tesla valve.
  • The structure may allow sharks to better survive long breaks between feasts.

“Acoustic tweezers” use sound waves to levitate bits of matter

The non-contact technique could someday be used to lift much heavier objects — maybe even humans.

Levitation by hemispherical transducer arrays.

Kondo and Okubo, Jpn. J. Appl. Phys., 2021.
Surprising Science
  • Since the 1980s, researchers have been using sound waves to move matter through a technique called acoustic trapping.
  • Acoustic trapping devices move bits of matter by emitting strategically designed sound waves, which interact in such a way that the matter becomes "trapped" in areas of particular velocity and pressure.
  • Acoustic and optical trapping devices are already used in various fields, including medicine, nanotechnology, and biological research.

Cockatoos teach each other the secrets of dumpster diving

Australian parrots have worked out how to open trash bins, and the trick is spreading across Sydney.

Surprising Science
  • If sharing learned knowledge is a form of culture, Australian cockatoos are one cultured bunch of birds.
  • A cockatoo trick for opening trash bins to get at food has been spreading rapidly through Sydney's neighborhoods.
  • But not all cockatoos open the bins; some just stay close to those that do.

    Godzilla and mushroom clouds: How the first postwar nuclear tests made it to the silver screen

    The few seconds of nuclear explosion opening shots in Godzilla alone required more than 6.5 times the entire budget of the monster movie they ended up in.
