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.

I am proud to say I search for this! Was finishing my afternoon hospital shift and it just came to me to find out history of telling time.
@killah5x X have a good one, as Americans say.
I was watching a video of the Greek Olympian games and someome commented it would be hard to measure how quick they were since they had no stopwatches.
But another person commented they had sand clocks and water clocks. I searched what water clocks are and brought me here.
And here’s me replacing a quartz wall clock with a vintage pendulum mechanical one
Just repaired my grandfather clock. Hasn’t run in 20 years
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.
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 ?
Would love to know if you’ve found videos that explain the how.
Hi i from India and i thought that this is very good explaination ever....
I like the explanation very well👍👍👍👍👍👍👍👍
I think they used sundial to compare
Observatories played a part in the timing of clocks and watches
@@oscarosullivan4513 So, you're saying that they were comparing against sidereal day measurement?
Interesting, great and concisely informative; thank you.
Thanks I really needed this because I was planning to make a story in the medieval times and was wondering how they used their time
Have u done ur story
@@thirumoorthy7416 I haven't finished it yet unfortunately, because of lack of motivation and I have classes
Even I had a plan to make story of this., Thats why I asked you
Why dnot we just share our thoughts?
@@3Illyas I hope you do end up finishing it, im interested!
@@3Illyas bruh when the video is gonna go up? It's getting 2 years already
excellent presentation! Thank you.
Thanks a bunch for the details🙏
Thank you very much for your explanation!
Great video.
The constant ticking was super distracting for me 😂 felt like it was getting louder and louder
Thanks so much 💭⏳ 2:27

Well that's what we use now to calibrate but they didn't know that when clocks were invented.
My seventh grandfather was a clockmaker and i have one of his clocks!!! And it is working!!!
That’s crazy!
Did you grow up in a commune?
Now I want to know how much energy has been expended in developing and keeping time since someone actually thought of it as important. Go.
The finger counting part is a trip.
you did not mention that the rythm of the clock is in sink with our heart which is circadian rhythm.
Sun dials technichally could work at night, moonlight can get bright at night, in non light polluted areas, and cast shadows. In those times as well, there is no light pollution, so they arent useless at night.
Edit: they could also use torches or other manmade sources of light to replicate the sunlight for the sun dials, so no actually, they arent useless at all at night.
Timing is everything and timing is everywhere.

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.
Thanks a lot
Whoa, hearing background music from Eschalon: Book II in this video really threw me off for a while.
Its Saturday morning, and now I know why its 11.48am. Thanks!😁
Forgot about sundials. This video needs to be redone.
The jump from water clocks to precision clocks is a little baffling, surely there's steps in-between ??
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'?

She just told me how to build a time machine the correct way.
⏰📅+ 🪨 Crystal quartz + ❄️/🔥 Environment for not loosing time + machine for a portable +🔋🔋+ make sure the ⌚ and 📅 is connected to the device and not just time = Time Travel.
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?
Where do you think Egypt is?
I find phones draw me in so I use a watch
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 You have made yourself clear best analogues for night would be Timex expeditions
@@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)"
( Leave your comment English )
Very informative , whole lotta thanks for the post tbh
Weird, time to look into crystals.
0:35 "Today time is tucked away in our pockets"
If you said that to someone 15 years ago they would think you were talking about the 1800s/early 1900s lol
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.
Candle clocks were used by Alfred the Great
The roster is still my modern day time, crow every half hour
6:40 that guy looks like Isaac ngl
6:29 pope Sylvester II introduced first clock to uncivilized western europe. He copied it from islamic Spain. He studied there.
The medival period mechanical clock ( ibn al haytham and al jazari clocks) from Arab muslim world is missing in this video.
This is literally just "time is a human construct" but explained
Quantum clocks.
After just NK*😅
What about hourglasses/sand clocks? They don't even get a mention.

w o a h the comments be looking dry
150 animals become extinct every 24 hours??? damn
Quartz watches aren’t powered by quartz. They are powered by a battery the quarts just regulates the ticking of the watch.
Come to visit konark temple
Have a S.A on this So thank you 😃
But it is also pretty!
poggers
After just nk
There are atomic wristwatches
Your forgetting Newgrange

This study puts Rolex perpetual date watches in the mud. I knew it.
Asia is not only Chinese.
Monks, go figure.
The start of the video needs to be in a movie i will make the best movies one day 0:00 0:29
😠 Cesium!
😮 Sieze him? Why?
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.
Wish I had a time machine so I could go back and kick the guys ass who came up with Time, Clocks, Work, Work Week, 8hour shits, Calenders
❤️🇺🇲👍☺️
U
It's time to use a decimal time system. France started with decimal time, C10 system improved it, UDAT system improved it even more. In UDAT system, date and time is an one string. PM me if you want to know more
Tons of wrong information.
You gave the credit for the work that Indians did to Mesopotamians, and the credit for the Roman's work to Egypt. just to name a few.
That's wrong info??!! r u sure?????? i just finished creating a HUGE comic strip based on this!!!! for my school project!!!
@@Spidxy291 I believe you
Tom Woods the anarcho capitalist?
Check out the antikythera mechanism perfect example of our beautiful time cycles on our beautiful NON ROTATING FLAT EARTH in the magnetic CENTER MASS OF THE WHOLE UNIVERSE
200 species go extinct per day?
Anyone here due to daylight savings 2020?
Anyone here understand this illiterate moron's question?
Don’t worry 2022 is most likely
I wanted to watch the whole video but I ran out of time.
You must love Jehovah your God with all your heart and with all your soul and with all your mind and with all your strength. You must love your neighbor as yourself. Jesus the Anointed is Lord!
Oldest civilisation of India is not even mentioned. Poor awareness.
Pretty amateurish take on the subject. I wanted to like but i just cant.
Stop nonsense
Had to steal someone elses calender and make it your own did you? You couldn't give credit to the Church for making our calender so incredibly precise and say "BC", not "BCE"
Edit: she said "BC" the second time
Don't say heck, it's vulgar and unprofessional
I was thinking the same thing, hell is much more appropriate
JESUS CHRIST DIED AND ROSE THREE DAYS LATER FOR OUR SINS. REPENT AND TURN FROM YOUR SINS AND SURRENDER YOUR LIFE TO CHRIST AND OBEY HIS COMMANDMENTS. COME TO CHRIST WITH CHILD LIKE FAITH AND TRUST IN HIM. WALK WITH JESUS FAITHFULLY AND OBEDIENTLY TO THE END. “BUT HE THAT SHALL ENDURE UNTO THE END, THE SAME SHALL BE SAVED” MATTHEW 24:13. UNLESS YE REPENT, YE SHALL ALL LIKEWISE PERISH
PATHETIC lies.
why does everyone lie about this?
