Re: Perpetual calendar
Hi;
Let past 1600 be whatever it was!
That is the right idea.
In mathematics, you don't understand things. You just get used to them.
Probability is the most important concept in modern science, especially as nobody has the slightest notion what it means.
90% of mathematicians do not understand 90% of currently published mathematics.

Re: Perpetual calendar
Had I seen the Sakamoto's algorithm earlier, it would have saved a day of mine!
Anyway, I'm happy about it.

You can never understand something until you do it yourself. Discover it for yourself. That is better than reading about it.

Yes, that's true.

Re: Perpetual calendar
Actually, I received a hoax mail, like this one: http://www.snopes.com/inboxer/trivia/fivedays.asp
Then I wrote a program to list out the occurences, and mailed that list to the sender!
Later, I wanted to try out a day of the week formula.

Re: Perpetual calendar
Yes!
It's disgusting when people act without thinking.
I get outraged when I see the media too acting like headless chickens.

Re: Perpetual calendar
Hi gAr;
I do not know about the media elsewhere but over here they are awful. Twice I was involved in a newsworthy event. Both times I picked up the newspapers the next day. In both cases they did not get any part of the story correct. It was as if they were never there but I knew they were, they interviewed me.

Re: Perpetual calendar
Well, it's the same all over the world I guess!
Media like spreading fake news, gossips, fear, tomorrow is EOW, bombs, patent trolls and some more.
Nothing good happens in this world, they say!

Re: Perpetual calendar
Hi;
They are supposed have some sort of journalistic responsibility to report the truth. You know I never listen to the news anymore. I go to the internet. I would rather listen to some crazy person whom at least believes he is speaking the truth than to listen to those who lie on a daily basis.

Re: Perpetual calendar
Hi,
Yes, so true!
Here it's less of beer and more of washing powder, free pen with soap (what a combination!), etc.
In the browsers, we can atleast block the Ads with ad-blockers, we control what we like, that's what fascinates me!
Anyway, it's late here. See you tomorrow!

Re: Perpetual calendar
Hi gAr;
See you in a bit.
You would think with a whole race of bloated beer drinkers that they would not have to advertise. My father used to say instead of spending millions on garbage advertising why don't they lower price?
Nope, guys who went to Harvard, and have 824 degrees in economics are powerless to figure out how to keep prices down. Just pass it on to the consumer, yep that will work. Do you need a Harvard education for that?

Re: Perpetual calendar
hi gAr
Would there be any further correction, say after 10000's of years.
The leap year adjustments are made because the time for the Earth to orbit the Sun is not an exact number of days.
Adding an extra day every fourth year is to avoid precession of the seasons.
The fourth century adjustment is to correct because it's not 365.25 days = 1 year either.
There must be a time in the far distant future when even those two adjustments aren't enough. Could google it or I'll work it out if you want. Might take a while though.

Re: Perpetual calendar
Hi;
This calendar will lose a day or so every 3000 or so years. There is an adjustment on the leap years that will only lose a day in 44 000 years.

Re: Perpetual calendar
Hi all,
There's some info here: http://en.wikipedia.org/wiki/Tropical_year
Looks like it's not decided yet.
After all, the orbit won't be the same always!

Yes, it is important to remember that modern astronomy like all the other sciences are just approximations. Calculations far into the future are impossible due to sensitivity to initial conditions.

Re: Perpetual calendar
If there were no resistance to motion, perpetual motion would work. However; It would still be useless for as soon as you want that motion to work for you, you would be causing resistance and the motion would diminish and stop.
