Water Cooler / This and that / Re: Figure Out These Number Sequences
« on: January 29, 2013, 09:11:08 PM »

Slightly Tricky:
1, 2, 5, 10, 17
Is it possible that this one has an error in it?
I'm guessing the next number should be 28. If so, I think the sequence has an error early on. Perhaps it should be:
1, 2, 4, 7, 12, 19, 30
Would that make more sense? Or, did I miss the sequence on this one?

You are going to kick yourself, Scott. Actually, the sequence is just (n^2) +1 
1, 2, 5, 10, 17, 26, 37, 50, 65, 82, 101 |

Here are some interesting number sequences. Can you figure out what they are?
Some advice: Don't waste too much time on the, "Outside The Box" sequences. You will not figure them out unless you Google them.
Freebies:
1, 2, 4, 8, 16
0, 1, 1, 2, 3, 5
0, 1, 3, 6, 10
3, 1, 4, 1, 5, 9, 2
2, 3, 5, 7
1, 2, 6, 24, 120
Slightly Tricky:
1, 2, 5, 10, 17
1, 11, 21, 1211, 111221
59, 154, 605, 1111
1, 4, 27, 256
Math Comes In:
125, 376, 188, 94, 47
1, 2, 6, 20, 70
1, 1, 3, 11, 45, 197
1, 1, 5, 61, 1385
6, 28, 496, 8128
1, 5, 14, 30, 55
1, 2, 5, 15, 52
1, 2, 5, 14, 42
Outside The Box:
4, 8, 15, 16, 23
14, 23, 28, 33, 42
5, 9, 14, 27, 29, 54, 59
Here are the explanations:

I had no idea that "Dear Abby" was even still alive. I do recall reading the advice column that her identical twin sister, Ann Landers wrote back in the day. She passed away in 2002.

Water Cooler / This and that / Re: Have You Ever Seen A Wind Map?

How many airplanes are in the air right now in your area of the country? You might be suprised. Check out this flight radar map. Sometimes when you zoom in or out you need to be patient for a few seconds for the planes to catch up. You can click on any plane to get more specific information about it.

I think this website goes nicely with the wind map website which is why I am posting it in this thread. |

The Tech Section / Science / Space / Making Atoms Colder Than Absolute Zero?
« on: January 05, 2013, 06:03:46 PM »

This is really hard for me to believe, but apparently some scientists have discovered a way to make atoms COLDER than absolute zero. This is accomplished with the clever use of laser beams and magnetic fields to very finely tune the atoms into a negative temperature reading.
This discovery may eventually lead to the development of engines that are more than 100% efficient and shed light on the dark energy that supposedly makes up 70% of our universe. I read the article below several times and if it is true then it is an amazing discovery. Remember cold fusion though...
