The need for them came from relativity, but the atomic clocks needed to be able to handle such fine corrections are based on the hyperfine transition of 133Cs. You're not getting very far on atomic clocks without particle physics
Again, is this a European thing? I've never heard of a shed dedicated to storing bikes....I can see this is brewing used as an analogy for something else, but the shed/bike concept itself is foreign to me.
Sounds like Newton. Long tradition, I guess
"Well...it seemed like a good idea at the time...."
Never heard of one or seen one before...is this a European thing?
What is left to change besides oven and microwave times?
One...the most IMPORTANT one....my internal clock....
That really takes close to a week to get fixed every time.....it throws all of us humans off to some degree.
Oh...and my dog....I have to adjust her schedule twice a year too....
JUST PICK ONE AND STICK WITH IT....
I want to quit the damned changing in my lifetime.
"Okay, nuclear power. Yeah. Yeah, they did give us that. That's true. "
"And industrial-scale superconducting magnets!"
"Don't forget GPS satellite relativistic corrections!"
"And radioisotope therapy!"
"Electron beam therapy?"
"World Wide Web, wasn't that created by particle physicists?"
"Yeah, they did do that."
"Capacitative touchscreens too, you know."
"All right, all right, FAIR ENOUGH! But APART from computers, telecommunications, nuclear power, PET scans, MRIs, satellite communications, superconductors, radioisotope therapy, electron beam therapy, heat-shrink tubing, cargo and baggage screening, smoke detectors, muon tomography, capacitative touchscreens, and the World Wide Web, WHAT HAS PARTICLE PHYSICS EVER DONE FOR US?!"
"Synchrotron light sources for drug discovery?"
"Oh, drug discovery?! GROW UP!"
Yeah, what has a better understanding of particle physics ever done for US, huh???

if this were true it would not be possible for the system to read the watermark.
You confuse "invisible to humans" with "invisible to statistical analysis". Humans can't, for example, see the difference between metameric colours. Statistical analysis can. Humans can't see minor drift at scales where Brownian motion dominates. Statistical analysis can. Humans can't see the difference between background disease rates and new rising threats. Statistical analysis can. On and on. Statistical analysis is a far more powerful tool than human perceptual abilities.
this is also a lie. Identical thoughts must be expressed identically, otherwise they are, in fact, *different* thoughts.
I literally gave an example above. If you saw "picked a mango", "selected and picked a mango", "from within the tree, picked a mango", you would never think there was anything going on in the choice, and it isn't going to change the story one iota.
Even though some regions or countries stay on a shifted time offset year-round (which might look or feel like being "ahead" like daylight saving time), standard time is legally and geographically considered the baseline time zone for those areas. They simply choose not to participate in the biannual clock adjustments.
Countries & Regions That Do Not Change Clocks Most of Asia: This includes major industrialized nations like China, India, Japan, and South Korea, as well as most of Southeast and Central Asia.
Most of Africa: Almost the entire African continent stays on a single standard time year-round.
Parts of the Middle East: While countries like Iran and formerly parts of the Levant have experimented with it, places like Turkey and several neighbors maintain fixed times.
Parts of Europe: Iceland, Belarus, Russia, Georgia, Armenia, and Azerbaijan do not practice seasonal time changes. (The European Union has debated abolishing the practice entirely, but member states still currently shift together).
Much of South and Central America: Countries like Argentina, Brazil (which abandoned nationwide DST a few years ago), and most of their neighbors remain on permanent standard time.
Erm... notice a pattern there?
Most of these nations are equatorial or not that far off it. Most of them between the 26th parallels. As you get closer to the equator, there is less difference between the hours of daylight between summer and winter, as you get further you get a greater differential.
In Perth, Western Australia (36 S) there's about a 3 hour difference, in London, UK (51 N) there's an 8 hour difference and this difference does not neatly line up around 12 PM so if you had permanent GMT you'd have the sun getting up at 3 AM in the summer disrupting sleep and if you kept permanent BST you'd have darkness until 9 AM in winter causing chaos on the way to work/school.
Perth doesn't have DST (but the eastern states do so that causes problems) because the differential in daylight hours isn't much of an issue (that and Perth is incredibly backwards and resistant to change but that is another discussion entirely) however London does because there is a huge difference in daylight hours between winter and summer.
DST was made permanent in the USA in 1974, and it was so unpopular it got repealed the same year.
It sounds good until you have to live it... there are also morning people among us, and kids trying to walk to school where further darkness presents a safety issue. Not everyone benefits from potential extra sunlight to extend happy hour.
Before we had mechanical clocks, we used to adjust to the hours of daylight automatically. Daylight Savings came in because we needed to keep doing that as the hours of daylight changed with the seasons, so the solution was to change the clocks.
With most clocks being automatically updated these days, you barely have the excuse of having to change the clocks to oppose DST. You go to sleep on one time and wake up in the new one.
