I listened to it twice.  I really like it a lot.  I think I'll hook up my PC to the Bose system we inherited from my late Grampa and listen again.

Wow, that's really neat, b.  I sometimes take note of license plates and make jokes out of them in ways no one else could do without the codes I have in my head.  But...

But here is a great song I'm listening too that will make me remember 1720 I hope for #25, manganese.
By the way vivaldi lived 1678 to 1741, one of the few facts i know! 
Youtube this: VIVALDI (1720@) Concerto for Viola d'amore in D RV 392

All vivaldi songs recovered or known are indexed with RV numbers.  (BWC? what is bachs 3 digit code?)

Not in the 2009-2011 numbers I have, I don't think so.
But here is a cool one I just found:
Take #25, manganese, and then double it and add 4 for 54.
The number ends in 45 though, so that part is palidromic.
Then in the middle, if you reverse-mod the numbers with 10, then
then the Baroque date of 1720 becomes 9380.
The number is actually 54.938045

well molybdenum is incrementally simple: 95.96
And let me take a look on the chart for a sec...
be right back...
I'm back:  Cadmium is 112.411, so take out either the 2 or the 4 and have a palindrome. (#48)
And lead: 207.2, take out the 7. (#82)
Don't see any others this look.

#505 Re: Dark Discussions at Cafe Infinity » weight lifting miracle today » 2012-01-25 07:40:27

Hey!! I just noticed that potassium (K) has a palindrome-almost weight 39.0983
Without the 8 in there it would have been 39093, but the 8 is in it, so that threw me for a loop till now.
So #19 on the chart, I'm just doing this for my own benefit, is 39093 then 3909[bold]8[/bold]3, yeah!!

I'm not really attached to possessions, though I wouldn't mind having a second clarinet in case the first one breaks down in a concert that I play every other year!  but i would like have enough money to live in a cheap apartment in the north-east and
move whenever I feel like it in search of my true love...  The leftover lottery money can go to the homes for the homeless.

#507 Re: Dark Discussions at Cafe Infinity » weight lifting miracle today » 2012-01-25 07:25:14

Well if I ever become rich or win the lottery, I promise I will
build a home in a town I love, and allow homeless to stay
there 23 hours and 59 minutes a day.  They have to leave
for one minute at least every day to get some fresh air.
Gotta have some rules, right?

#508 Re: Dark Discussions at Cafe Infinity » weight lifting miracle today » 2012-01-25 07:19:12

Your last sentence says you are sure and probably, just thought i'd point that out.  I won't pick on you unless u don't care.

#509 Re: Dark Discussions at Cafe Infinity » weight lifting miracle today » 2012-01-25 07:13:49

I see mostly men as well, however I have seen a couple women that certainly look homeless, not sure if they are though.

#510 Re: Dark Discussions at Cafe Infinity » weight lifting miracle today » 2012-01-25 07:09:42

Are there more homeless women between 22 and 44 years of age in the USA or more homeless men of the same age range?
Any idea?  I don't know the answer.

#511 Re: Dark Discussions at Cafe Infinity » weight lifting miracle today » 2012-01-25 07:03:23

There are probably some happy animals in the forest (les bois/ le for^et) that eat better than some of the most unfortunate of people on this planet.

#512 Re: Dark Discussions at Cafe Infinity » weight lifting miracle today » 2012-01-25 06:58:19

Well I wouldn't go that far.  Some people live without computers still and sell newspapers and wash windshields in a downtown, and have missing teeth too.

#513 Re: Dark Discussions at Cafe Infinity » weight lifting miracle today » 2012-01-25 06:54:31

The whole world is interconnected, so I guess maybe it might have something to do with PIPA and SOPA being written so poorly, just a guess.

#514 Re: Dark Discussions at Cafe Infinity » weight lifting miracle today » 2012-01-25 06:51:38

I don't remember it word for word, it is about 900 words plus or minus a multiple of 22.
I won't try to summarize it since that would be silly since they already wrote it in plain english.

#515 Re: Help Me ! » Trigonometric equation » 2012-01-25 06:49:05

So I suppose you could assume there are y = x and y = -x, which point to the 45 degree (pi over 4) mark in each of the four quadrants, making four answers where c = +/- the sqRoot of 8, about 2.82842 rounded upward with the next digit.

#516 Re: Help Me ! » Trigonometric equation » 2012-01-25 06:44:55

My calculator from the dollar store points to the fact that 45 degrees (known as pi over 4) makes c squared=8 exactly.
All other values appear to have c squared larger than 8, but this is just silly math ofcourse.  The calculator is just a sampling of inaccurate values!

#517 Re: Dark Discussions at Cafe Infinity » weight lifting miracle today » 2012-01-25 04:04:35

oh no doubt!!  Maybe after I get to more important tasks such as getting all the elements weights into my head and back out as needed without error.  Also, I must say, googles new terms of service are wonderfully written in plain simple English.  I am so impressed I wrote to them.

#518 Re: Dark Discussions at Cafe Infinity » weight lifting miracle today » 2012-01-24 12:37:09

I think I'll eat something else now too.
My book lists all the primes and the residue result loops from 3 to 1999.
the book is hardcover, about and inch thick, 1.25" with covers.

#519 Re: Dark Discussions at Cafe Infinity » SOPA Defeated? » 2012-01-24 12:30:58

I searched opencongress.org or something like that for 10 minutes and couldn't find any actual vote on PIPA 968.

#520 Re: Dark Discussions at Cafe Infinity » weight lifting miracle today » 2012-01-24 12:19:40

mult by 5 to next number and using 1009 prime for mod reveals that it looped twice in 1008, at a length of 504.

#521 Re: Dark Discussions at Cafe Infinity » weight lifting miracle today » 2012-01-24 12:16:11

I'll do 5 with 1009 again and get better results on the loop length...

#522 Re: Dark Discussions at Cafe Infinity » weight lifting miracle today » 2012-01-24 12:00:05

Yes I tried 1009 with my BASIC program.
I tried whole numbers from 2, 3, 4, ... 9, 10, and then 11 worked, just like my book uses 11 for the multiplier to get to the next number in the loop.  For all the numbers 2 to 10, it repeated at some fraction of 1008, sometimes 12 times smaller, or 6, or maybe others.

#523 Re: Dark Discussions at Cafe Infinity » SOPA Defeated? » 2012-01-24 11:41:11

I didn't read a complete vote count anywhere.  But I see some supporters have pulled out.

#525 Re: Dark Discussions at Cafe Infinity » weight lifting miracle today » 2012-01-24 11:28:30

Oh, my book lists 997 and 1009 as the only primes that surround 1000 or 1001, so 1001 is non-prime.
Maybe I should factor it.
