Why do we need to coordinate the way we measure time? And how do atomic clocks work? Find out with Leon Lobo, Head of the National Timing Centre (NTC) programme at the National Physical Laboratory.

I thought all serious scientists used a ping pong ball bouncing in a train to measure time.

Considering the devastating affects if time is displaced eg by cyber attack etc. I wonder just how well it is protected?

Wow, so much valuable info in this video! With longer videos, it can be hard to retain everything.Anyone know of any AI tools that summarize key points from KZfaq videos?

You said that atomic clocks are driven by radiation at a given "energy". However, given that radiation energy can also be defined as wavelength can it be said that you are using one atomic frequency clock to drive another atomic frequency clock? What method could you use to check the frequency of both clocks?

I am so interest to know what do American use. Cheeseburger cooking time? What’s the freedom unit for time?

" Нет ребята, всё не так, всё не так ребята" Владимир Высоцкий. Что же такое время? Вероятно придётся начинать анализ образования времени с образования материальной частицы как основы материального мира. Задача анализа образования материальной частицы сложна на первый взгляд, но, сложность возникает по причине устоявшихся представлений, или, ...... .Однако, время течёт непрерывно только где есть движение частиц по кругу, где движение начинается и заканчивается вне окружности, такое движение анализируем всё равно относительно движению по окружности. Есть малые окружности и там своё время цикла, но, малые окружности входят в сферу больших окружностей и соответственно в больший цикл.К чему сей анализ? Материальный процесс обладает своими законами, а разобраться и осознать эти законы предстоит тем, кто пришёл в механику материальных процессов. Выходит, приходим в материю, как не крути. Обоснования точности времени, очень нужно, но, желательно осознавать саму суть времени.

Time is an illusion, lunch time, doubly so.

I don't think time can be measured. Clocks just track duration, based on a set of rules. 😉

All this because trains went fast enough to notice and needed a way to schedule pick up and drop offs. Yet the meaning of noon is about as far from what this guy is talking about as possible.
