Oct 8 2024 - What time is it, google?

 

That's one of the top 3 questions on a regular basis - what time is it google?

The importance of time.  When did time become important?  Perhaps always.  So important that the Babylonians and Egyptians measured time at least 5,000 years ago.  Calendars organized communal activities and public events, scheduled shipments, and regulated cycles of planting and harvesting.  They used the solar day, the lunar month, and the solar year.  

I guess I could manage the solar day - I have a few sundials in the garden as decorative elements.  It would take a lot of skill to accurately use a sundial.  

 There is so much invention in clocks and time pieces.  I read through the history in a breeze, but it is a substantial body of knowledge and engineering.

 What is being worked on now?

 NASA wants to come up with a way to keep track of time on the moon - an entire frame of time reference for the moon. " Because there’s less gravity on the moon, time there moves a tad quicker — 58.7 microseconds every day — compared to Earth. So the White House Tuesday instructed NASA and other U.S agencies to work with international agencies to come up with a new moon-centric time reference system."  And a funny thought: "Unlike on Earth, the moon will not have daylight saving time."

From the New Scientist: "Any random sequence of events, such as the lapping of ocean waves on the shore, can become a clock – and physicists have now devised a mathematical procedure for making such an odd timepiece and for measuring its precision."  That article isHERE except you have to subscribe to read it.

And from Euronews - Melting ice caps.  The human-caused consequence of climate change is slowing the speed at which the Earth rotates, increasing the length of a day... by a few milliseconds.

And interspersed in the news about time is the news in Time Magazine.  It was going to be called Facts, but then the name was changed to Time with the slogan - "Take Time - It's Brief".

That's the clock tower at Filoli Gardens, south of San Francisco.
