A real conversation I witnessed between two adults mid January 2000
Isn’t it ridiculous?
What is?
This business of fighting who is going to see the new Millennium in first. Some Islands in the Pacific, I think they are called Kiribati, claim that they are going to be the first piece of land on the Globe to welcome the new Millennium in.
So what? Would that give them any advantage?
Money of course. The rest of the world would rush out there to celebrate.
Celebrate what?
The new Millennium dumb.
I must be dumber than I thought. When does the new millennium start?
00.00 hours on December 31st 1999 or 1st January 2000 depending on the way you look at it.
Now I know I ‘m dumb. Where does 00.00 hrs belong? To 1999 or 2000?
Are you looking for an argument? Nowhere you idiot. It is a fine dividing line between the two days and it is supposed to happen out there in the Pacific on what they call the International Date Line.
Is it just for the Millennium or does it happen every day?
You are completely clueless aren’t you? Of course it happens every day.
Every day of every year?
Of course;
No it doesn’t.
What did you say?
I said NO IT DOESN’T!!!
Go away. Find something to do. Better still I’ll give you some razor blades to go out and play with!
Ok ridicule me if it makes you happy, but I still say IT DOESN’T.
All right smart Alec elucidate please.
On with your fancy words again?
Explain
Oh well. You know our friend Jeffrey?
He is not our friend he is your friend.
Well whatever. On his birthday it doesn’t happen.
Don’t be ridiculous. Of course it does.
No it doesn’t. He was born on February 29th. So you see it doesn’t happen every day of every year. Unlucky: he only gets presents once in every four years.
Just like you to come out with something like that. That’s because he was born during a leap year you imbecile.
1-What’s the matter with you today you look so upset.
2-I am. I have lost two good friends and I don’t want to talk about it.
1-It sounds as though you should discuss it with somebody to ease the pain.
2-Perhaps you are right. You didn’t know them but they were a loving couple, adored each other, very popular with everybody.
1-Were? Surely you mean, “Are”.
2-If you don’t stop it I’m going to burst out in tears. They are both dead.
1-Oh I’m so sorry. I though you just had a fight and broke off your friendship. I didn’t realise it was that serious. What happened?
2-They moved to St. Francisco 10 years ago, on this very day. They decided to go to Japan with friends for a well-deserved holiday and that’s when it happened.
1-Air crash? I didn’t hear.
2-Nothing that simple. They flew out all right but they had planned to return on a luxury liner from Tokyo via Honolulu. You know these “fly there sail back, or sail there and fly back” type of travel arrangements.
1-So what happened?
2- A week gone by Bill receives an urgent message from his office to get back urgently a few hours before they were due to sail. Vicky stays with friends to return on the liner as originally planned. Bill catches the 06.00 direct flight to Frisco on the Monday the same day the liner was due to depart at 10.00 hr
The ship sailed on time. After a nice lunch with plenty of Californian wine Vicky and friends decide to climb up to the upper deck for a stroll and some basking in the sun. On the way up Vicky slips, tumbles over, sustains a fatal head injury and dies within minutes of the fall. The ship’s doctor records “accidental death”, at 14.37 on July 6th”.
Meantime Bill lands safely at “Frisco” after a 9 ½ hrs flight arriving home at 21.43 local time to find a telegram waiting for him announcing Vicky’s accidental death. He has a heart attack and expires on the way to hospital. Death certificate “cardiac arrest” at 22.45, July 5th. Bill had crossed the Date Line and lost a day in the process
Vicky’s death certificate on the other hand was issued after reaching port at Honolulu, a week later and the time of death was recorded according to the entry in the ship’s log book i.e. 13.36 July 6th !!!, one day after Bill’s heart attack. !!!!!!
There were no children in the marriage therefore Vicky’s survivors lay claim to Bill’s vast estate worth over $100 Million. Bill’s survivors contest the claim arguing that Vicky died first, however the courts accepted the dates as they appeared on the death certificates to generate a long legal battle between members of the two families squandering away most of their fortunes
-I was just thinking. It could have happened the other way.
-What do you mean?
-Oh dear, another session of cluelessness coming up.
-You are a puzzle and a half today.
-Imagine Bill flying the opposite way from Frisco to Tokyo, having an accident when he gets there, Vicky receiving the news of Bills death and has the fatal heart attack.
-What in Heaven’s name are you talking about?
-This blasted International Date Line.
-Go ahead give me another lecture.
-Don’t you see? Bill would have gained a day, therefore, on paper, he would have died after Vicky . Anyway, I don’t want to talk about it anymore. Let’s change the subject.
Μιχαλη πολυ ομορφα τα ανεκδοτα σου και κυριως ενδιαφεροντα με το θεμα της αλλαγης ωρας
και της διεθνους ωρας ... μας εχει ψιλοαπασχολησει παλαιοτερα ... μαλιστα αναφεραμε οτι σε καποιες χωρες
οι διαφορες ειναι και με ημιση ωρων
As we are going to be talking about time the way to devide it up and subsequently measure it I think a definition may not go amiis at this juncture.
Time=the interval between two events.
It can be two events in history thousands of years apart or two momentary events separated by a few milliseconds.
Although primitive man was merely concerned with survival, a natural division for his basic needs was still needed. Originally it was just light and darkness, the day and the night.
Archaeological evidence indicates that the beginnings of dividing up the day to serve man’s daily needs, albeit crudely, goes back about 30/40,000 yrs, before
one of the most important events in human history took place around 10/12000 years ago. Man begun to cultivate plants and domesticate animals.
This emergence in agriculture and animal husbandry set the stage for the appearance and expansion of villages, towns and finally cities contributing to a rapid, continuing growth in human population, and an increasing appetite to understand, divide and record time in a more sophisticated way.
Before man could tell what time it was he needed a unit of measurement.
Natural and man-made units.
In a popular sense, a year is the complete orbit of the Earth around the sun. A further subdivision of nature’s cyclic motion is one full rotation of the Earth around its own axis, the day, and one full cycle of Earth’s satellite, the moon, approximately once in every twenty-nine days, the month.
To determine precisely the number of times Earth rotates around its own axis within its complete orbit around the sun, a fixed point of reference in the solar system, a star, is needed to record the exact number of passes If this star is the sun then the result will be 365 ¼ passes. This is called the solar year, or solar time, based on the solar day.
If the star is another heavenly body further away then the result is closer to 366 ¼ passes. This is known as sidereal year or sidereal time, based on the sidereal day.
Astronomers choose sidereal time as the basic unit for their measurements. That is because calculations are based on observations of great precision.
As the order of our daily lives is governed by the sun, not the stars, we compromised by devising an imaginary day called the “mean solar day” of a mean average length. This has resulted in corrections of 28/30/31day months and leap years 29 day February.
Astronomers position objects in space on the surface of an imaginary Globe, called the Celestial Sphere (above), based on the supposition that all objects are the same distance from the earth. The sun’s yearly path on this surface is called the Ecliptic. The coordinates of any object are called Declination and Right Ascension.
If the sidereal day is shorter than the solar day, it follows that the solar hour minute and second will be longer than its sidereal counterparts, admittedly by a nominal amount if one judges by standards gone by, but today’s standards are intolerant of such inaccuracies. Do we need to do anything about it? The question is discussed in later chapters.
Calculating problems.
The difficulties in calculating precisely the length of a standard day arise because of some of nature’s deliberate inconsistencies. The Earth’s shape is not a perfect sphere. At the equator it bulges out by 21 km, at the North Pole approximately 10 meters, and the South Pole is depressed by approximately 31 meters.
Pope Gregory XIII decrees the introduction of the Gregorian calendar in 1582.
By 1582, the Julian year was already ten days behind the solar year. Pope Gregory XIII corrected the error and, that year, the 4 October was followed by the 15 October. To avoid a repeat of this inconvenience, he decreed that three out of every four centennial years should be common years instead of leap years; the accuracy was such that in the future, the calendar would only be out by one day every 4000 years.
This means that in the year 2100, watches with a perpetual calendar will need a slight adjustment to move straight from 28 February to I March.
For ambitious watchmakers, the introduction of the Gregorian calendar was the perfect opportunity to come up with a solution enabling the clockwork mechanism to cope with the irregularities of the calendar and to display the correct day, date and month on a "perpetual" basis. The perpetual calendar mechanism was the brainchild of Elysee Golay, a watchmaker from the vallee de Joux. In 1875, Jules-Louis Audemars and Edward-Auguste Piguet created the first perpetual calendar pocket-watches, the fruit of their determination to make watches of the utmost complexity. The mechanism comprised 190 different components mounted on an independent plate fixed onto the front face.
In 1978, the Manufacture made its most spectacular breakthrough in this field. Audemars Piguet introduced the first automatic Perpetual Calendar wristwatch, which is still today, the slimmest in the world (its clockwork movement is only 4.05 mm in height. Spurred on by the outstanding success of this timepiece, the master-watchmakers subsequenrly developed a perpetual calendar ladies' watch which was launched in 1989.
Nine years later, to celebrate the twentieth anniversary of the Classique Perpetual Calendar watch, Audemars Piguet brought out a unique, limited edition watch of which only 80 standard versions and 20 skeleton versions were made. Housed in a Millenary case, it had a pink gold rotor engraved with a skeleton "20" underlined with the words "Perpetual Calendar. "Perpetual" tribute to the glory of time, this watch embodies the craftsmanship of the Audemars Piguet watchmakers.
Μιχαλη μας εκπλησεις ολο και περισσοτερο....
δεν θυμαμαι να ηξερα οτι το πρωτο perpetual ηταν της Audemar Piguet .... εδω πρεπει να μας πει κατι και ο φιλος wostep
που εχει κανει αρκετες σπουδες σε αυτα τα θεματα στο wostep και εσυ επισης γνωροζεις καλά Μιχαλη
