We mechanized ourselves

A Briefer History of Time: How technology changes us in unexpected ways  
Fusion. Feb 18, 2015

From smartphones to smartwatches, clocks are everywhere these days. But have you ever wondered what life was like before we could measure time? Video essayist Adam Westbrook delves into the story of the clock, and discovers that when we learned to mechanize time, we accidentally mechanized something else.

When we mechanized time, we also and completely by accident, mechanized us.
Now we don’t eat when we’re hungry; we eat when it’s time to eat.
We don’t sleep when we’re tired; we sleep when it’s time to sleep.


Time ‘Emerges’ from Entanglement

Quantum Experiment Shows How Time ‘Emerges’ from Entanglement

Time is an emergent phenomenon that is a side effect of quantum entanglement, say physicists. And they have the first experimental results to prove it

Resetting the Theory of Time 
May 17, 2013

In his book Time Reborn: From the Crisis in Physics to the Future of the Universe, theoretical physicist Lee Smolin argues that time exists

Albert Einstein once wrote: People like us who believe in physics know that the distinction between past, present and future is only a stubbornly persistent illusion. Time, in other words, he said, is an illusion.

Many physicists since have shared this view, that true reality is timeless.

What about time as a fourth dimension?
SMOLIN: Well, time is nothing like a dimension … what’s characteristic about a dimension of space is that you can choose to go to the left, to go to the right. … We have no choice about going forward in time.
We have no choice about where we are in time.
We have no choice about the fact that almost everything that goes on in our lives is irreversible and can’t be restored or reversed.


Is Time Real?

As a physicist, though, it was a fun bone to chew on, and maybe, just maybe, he’s onto something.

The Universe > Season 5. 08/19/2010
One of the Universe’s most enduring mysteries is Time Travel.
In this episode, we explore the possibilities. Discover why Time Travel into the future is unavoidable in the Einsteinian world of Relativity.
As for the past… the laws of physics do not tell us it’s impossible, but the bizarre consequences of going into the past and altering the future make for mind-bending science.
