Yeah, but these new clocks aren't going to change the fact that time is an illusion, and vacation time doubly so. -

Science is almost ready to "redefine the second" with this new research by Sayan Sen Image by Samer Daboul via Pexels In an effort to make keeping time even more accurate, researchers from six European countries joined forces to compare ten ultra-precise optical clocks at the same time — something that’s never been done on this scale before. These clocks, which use lasers to measure how atoms jump between energy levels, are much more accurate than traditional cesium atomic clocks. In fact, optical clocks could lose or gain less than a second over billions of years. To see how closely these clocks agreed with each other, the team ran 38 measurements known as frequency ratios. Four of these had never been done directly before, and many were done with better precision than ever. The experiment helps move us closer to updating how the world defines one second potentially switching from cesium clocks to optical ones. Helen Margolis from the UK’s National Physical Laboratory said, “The accurate time and frequency signals provided by atomic clocks are essential for many everyday technologies like GPS, managing power grids and keeping financial transactions in sync.” Connecting these clocks over long distances was tricky. Scientists used two linking methods: GPS signals from satellites and custom optical fiber cables. GPS was accessible to all clocks but didn’t offer the best accuracy due to noise and signal issues. Fiber links used in France, Germany and Italy offered 100 times better precision but could only cover short distances. For clocks in the same lab, like those in Germany and the UK, short fiber cables helped reduce uncertainty even more. The findings were published in Optica, a journal focused on optical science. The team also looked at how the various frequency ratios compared across the different systems to spot any mismatches or patterns. “These measurements provide critical information about what work is still needed for optical clocks to achieve the precision and reliability required for use in international timekeeping,” said Marco Pizzocaro from Italy’s INRiM. He added that the setup acted like a distributed lab, which could be used for deeper physics research, like searching for dark matter or testing the foundations of physics. Coordinating all ten clocks and keeping them running in sync across six countries took a lot of preparation. Some results didn’t match predictions, but having so many clocks operating together helped spot where things went wrong. “Not all the results confirmed what we expected, and we observed some inconsistencies in the measurements,” said Rachel Godun from NPL. “However, comparing so many clocks at once and using more than one technique for linking the clocks made it easier to identify the source of the problem.” The researchers say more work is needed to cut down measurement uncertainty and make sure these optical clocks stay reliable over time. If they do, these clocks could soon be the ones we use to define time worldwide. As Thomas Lindvall from Finland’s VTT MIKES put it: “With a coordinated set of measurements, it becomes possible to check consistency while also providing more trusted results.” Source: Optica (link1, link2) This article was generated with some help from AI and reviewed by an editor.

Who goofed? I got to know. Wiki lists the internet speed of Singapore at 336.45 per Ookla, which would put them second behind Lyons France with the world's fastest median internet speed. -

Uranus releases about 15% more energy than it receives from the Sun, according to two new papers published in the journal Monthly Notices of the Royal Astronomical Society and the journal Geophysical Research Letters. The amount of heat a planet exudes could be an indication of its age: the less heat released relative to the heat absorbed from the Sun, the older the planet is. Uranus stood out from the other planets because it appeared to give off as much heat as it received, implying it had none of its own. This puzzled scientists. Some hypothesized that perhaps the planet is much older than all the others and has cooled off completely. Others proposed that a giant collision — the same one that may have knocked the planet on its side—blasted out all of Uranus’ heat. But none of these hypotheses satisfied scientists, motivating them to solve Uranus’ cold case. https://www.sci.news/space/warmer-uranus-14079.html

Question
Enphenate
Is it possible to create specific tasks in Outlook Calendar for specific users to see? I have a very small business with less than 5 employees and use Outlook's Calendar to sync daily tasks and events with everyone. The problem is, that everyone synced to the calendar can see all of the events. What I am trying to do is have me (the admin) be able to see the complete calender with all of my employees tasks/events, while each employee will have their own calender with their specific tasks, without seeing the complete calender. Essentially when I create a new appointment or task in outlook I would like to have the option to have It designated to a specific person so while they are on the go it can be synced to them directly.
I am willing to change to Gmail or another type of calender program if there are better alternatives to what I am trying to do.
I would appreciate any input or help!
