What’s the price of an accurate clock? Entropy, a new study has revealed.
Entropy — or disorder — is created every time a clock ticks. Now scientists working with a tiny clock have proven a simple relationship: The more accurate a clock runs, the more entropy it generates.
"If you want your clock to be more accurate, you’ve got to pay for it,” study co-author Natalia Ares, a physicist at the University of Oxford, told Live Science. “Every time we measure time, we are increasing the universe’s entropy."
As we go forward in time, the second law of thermodynamics states that the entropy of a system must increase. Known as the "arrow of time," entropy is one of the few quantities in physics that sets time to go in a particular direction — from the past, where entropy was low, to the future, where it will be high.
This tendency for disorder to grow in the universe explains many things, such as why it’s easier to mix ingredients together than separate them out, or why headphone wires get so intricately tangled together in pants pockets.

PING!
Fascinating.
No, the measurement of time is not creating entropy, it’s exactly the opposite!
Entropy is creating the concept of time.
Allowances for the inaccuracies of the Gregorian calendar have been around for a while. We have Light Years, with a few extra days added onto the calendar.
Going from Central to Standard time, one often loses a certain amount of awake hours, and for some that means less sleeping time. We know. But we keep using this method anyway.
Each year, there is an outcry to finally get rid of the time switch. Nothing has changed thus far.
I do not understand how people can reconcile be second law of thermodynamics with evolution. I know I’ve heard the explanations of adding energy to the system or that overall entropy increases but you can have small pockets where it decreases etc. To me they are still diametrically opposed
That’s what I thought.
Look into my eyes
We both smile
But can you without trying?
“This tendency for disorder to grow in the universe explains many things, such as why it’s easier to mix ingredients together than separate them out,”
Really? Try making a good vinaigrette or a homemade salad dressing. Getting the ingredients to properly emulsify and not break is a very delicate balance. Let them sit for any length of time and they separate on their own. I’m talking about all-natural homemade. Not commercial products.
Processes involving symbolic information can be used to create "self-organizing systems." In most life forms on Earth, this symbolic information is encoded in DNA and RNA molecules. Once it is represented in this way, information can be copied with almost zero errors, which is the key to evolution; here the word "almost" has as much significance as the word "zero."
But the second law is still in effect; living creatures use energy to power the systems and cycles that enable that information copying process, which takes place in parallel within billions of cells across trillions of living systems every second of every hour of every day. That expenditure of energy increases the disorder of our world, but the flow of energy from the sun keeps re-ordering things, and the two processes are in approximate equilibrium, and have been for several billion years, although the equilibrium point changes slowly over time. Well, usually slowly.
Time flies like an arrow.
Fruit flies like a banana.
Nature and all the critters probably laugh up their sleeves at our “clocks”.
I like the time switch. (It’s a matter of constant controversy between me and my husband; but so is the eternal thermostat battle, so...)
Little did they know back then what real crises would be unleashed upon the world by the increased accuracy.
Time to throw out the Casio's and replace them with Omega's.
The whole universe is looking in dismay everytime an accurate clock is built. Just don’t do it. You’ll kill us all.
I don’t really care what the actual ‘time’ is; I’ve always kept all my clocks ten minutes ‘fast’.
Learned from my Grandma. Never sure what the accurate time is, but never late for anything...
“What’s the price of an accurate clock? Entropy, a new study has revealed. Entropy — or disorder — is created every time a clock ticks.”
What a silly statement.
When a clock ticks it takes energy. Energy input is derived from enthlapy (a higher energy state that can be defined as order.) When energy is taken out of this state disorder is greater and thus disorder become greater and thus entropy increases. It is really pretty simple.
I think this was postulated a couple of hundred years ago.
Who owns the measurement of time? When did it start when will it end? What “scientists? Name them
I’m going to need Michio Kaku to explain this one.
Fight entropy. Stop clocks.
