What Time Is It?

[TOG]

Well, since it ended we can only re-use it if it's like our calendars where you can reuse an old calendar every 7 years. (Watch, I bet you five bucks TOG is going to check the math on that one :yes).

The Mayan calendar didn't "end". What happened was simply the turn of a "century", which in the Mayan calendar is 400 Mayan years. Their number system was based on 20, so there were 20 days in a month, 18 months in a year, 20 years in a "decade" and 20 "decades" in a "century". A Mayan "century" was 144,000 days long, which translates into 394 years, 7 months and 15 days, according to the Gregorian calendar.

I think Willie asked a brilliant question. Why are we adding a day to our calendars every four years when all we have to do is program into our electronic time pieces that additional correction so that it is never noticeable? History is full of these creative ways we've made abrupt time adjustments in order to compensate for the inconsistency of the movements of celestial objects. Modern programming can eliminate that altogether.

I did not know that's what he was asking. I thought he was asking why not make clocks that agree with sundials? That's how I took it.

You can't offset a clock to gradually change to make up for a leap day every 4 years. To do so would walk the clock around the daylight hours so that halfway through the 4 years noon would be midnight! We work by day/night daily, not the seasons. Case in point: There already is a clock that measures the true rotation of the earth: the sidereal clock. But it advances 4 minutes a day to make up for that extra day (rotation) since the earth rotates 366.25 times a year. But you would not want to eat lunch at "noon" every rotation of the sidereal clock as that would be different times of the solar day as the seasons changed.

Pretty much explains why they aren't around anymore.

Base 20...good grief. Wonder where they got that from...

And you see a problem with that?

What better way to break up the monotony of the ol' lunch routine. Am I right, or am I right?

evil computer of the devil, they use that hexademical system for printing back in the day.

I mean, come on. Does anybody really know what time it is?

Guess how many words per minute this dude types?

How about a base-12 system?

As a matter of fact, many things are base-12. We count things in dozens, there are 12 inches in a foot, and many things are either multiples of 12 or divide evenly into 12, such as 24 (2x12) hours in a day, 60 (5x12) minutes in an hour, 3 (12/4) feet in a yard and 4 (12/3) quarts in a gallon, among other things.

if you are using standard for a lot of that but if its metric then its base 10

Creepy. Just plain creepy. He's getting married in a month and he's still trying to figure out which one is his ring finger. Can't type a lick, though.

Interesting observation.

I bet by the time this thread is over you will have checked or corrected my math or my facts at least twelve times.

for those that use standard tools:

9/16=14mm
1/2=13mm
13/16=21mm
7/8=22mm
3/8=10mm

5/16 = 8mm

Am I right?

 

[jasonc]

5/16 = 8mm

Am I right?

yes, I was going to add that, 7/32=7mm

 

[jasonc]

those are close to each other and can work but what I have found is that Honda's lug nuts 19mm(3/4) don't take kind to standard impact sockets but my Nissan 21mm has no problem with me using a 13/16 on it.

 

[Jethro Bodine]

I'm curious what size socket my pastor has his slaves use on his Maserati lug nuts.

(this is the derailing thread, right?)

I think those only have 14mm lug bolt.

If I had more faith I would have known that.

I have changed a tire on one of those. cursed euros with those lug bolts. never got a good reason why those are still used. I hated changing those on the euros when a tractor tire on a tractor also uses lug bolts.
