A Brief History of Timekeeping | How Humans Began Telling Time | EXPLORE MODE
#Timekeeping #History #ExploreMode
A lot goes on in just 24 hours. But why is a day divided in 24 hours in the first place? Who decided how we would calculate it?
Today, time is tucked away in our pockets, just an unlock button away. It drives our technology, with atomic clocks being responsible for precise GPS location services and speedy internet search results.
Our ancestors, on the other hand, didn’t have it that easy. Time for them was written in the stars, in the sunrise and sunset, in the moon’s waning and waxing.
So how did we go from looking up to celestial bodies to looking down at our phones for time? What other timekeeping methods did ancient humans use before watches and clocks became ubiquitous? And what the heck is an atomic clock?
You’re watching Explore Mode and today, we are diving into time, and how humans developed technologies to measure it.

Both quartz analog clock and spring driven clocks which are regulated by pendulum or balance wheel consists of motion work (12 : 1 gear train that contains centre wheel with cannon pinion and hour wheel concentric with each other and minute wheel that transmits motion from canon pinion to hour wheel) to drive the hands of the clock forward is the same. In spring driven clocks not in all clocks but only in some clocks have second hand pivoted co-auxial with hour and minute hand so that it has one more wheel with thin and long shaft placed in the centre behind the regular centre wheel and transmission wheel is added to transfer motion from such a wheel to regular centre wheel. The same method is followed in motion work of analog quartz clock.

Good for your soul by adding beauty to your life.
Interesting, great and concisely informative; thank you.
the problem with this video and many others like it is that it doesnt address the issue of WHAT did the ancient inventors used to regulate / calibrate their clocks. Ok, so water comes out (or in, or candles burn, etc). How do they know when an hour has passed? How do they know if the flow was to quick / slow? Basically, what were they comparing against ?

I didn't notice until seeing the comment left by user "Ola Jallad" that this video is very much indeed from the North American / European perspective. Basically all of asia was just boiled down to China's method of timekeeping. I'm still curious to know about the other continent's perspectives. Like, how was all of this for Africa? And Australia? and basically every other culture?

Depends how profound you wanna get. Technically timing is nothing and nowhere, it's a human construct to help organize the chaos in which we seek to create order. And only time will tell, but only humans tell time.
you did not mention that the rythm of the clock is in sink with our heart which is circadian rhythm.

I remember people occasionally carrying pocket watches into the 1970s, especially when wearing a suit. The local pawnshop had many in the glass cases for cheap.
The constant ticking was super distracting for me 😂 felt like it was getting louder and louder
The jump from water clocks to precision clocks is a little baffling, surely there's steps in-between ??

Same but also I find I can't keep track of time with digital. I need an analog watch or clock to manage my time. With an analog clock I get to see how much time has passed and how much time is left. With a digital I have to make a bit of math in my head, which is a bit ironic because most people my age today think it's the other way around and that analog time is more complicated, but when you use an analog watch you are just looking at time not checking it. I don't know if I made myself clear.

@@Digital111 Same, I've always been visualising the analog clocks and watches that I have as a pie-chart of remaining time that I have for the day. Whenever I see the hour hand is at 9, im like "shit there's only 25% left time remaining for the evening (or 12.5% time left for the day)"

If up to 200 species become extremely 24 hours, how do we know and how many are taking over, or what animals are 'taking their place'?

Quartz watches aren’t powered by quartz. They are powered by a battery the quarts just regulates the ticking of the watch.

150 animals become extinct every 24 hours??? damn
If your watch is analog one way to determine if your timepiece is powered by a piece of quartz or gears as in a mechanical watch is to look at the second hand. If the second hand moves in a smooth sweeping motion the clock is mechanical if the second hand moves in a tic tic motion once per second then the clock is quartz.
