Warning: The following may prove educational Adding up numbers from 1 to N is easy with a computer. Try doing it in your head is a little more tricky.

For instance 1+2+3+4=10. (that would be the pins at the end of a bowling lane). Or 1+2+3+4+5+6 = 21, which is the sum of "eyes" on a die. So what is the sum of the numbers from 1 to 100?

The story I was told, was of a young German kid, whose teacher wanted a little peace and quiet, so he asked the class to perform this addition. Gauss, as he was called, ansvered the question a few seconds later: 5050

The idea is the following: Adding all the numbers from 1 to 100 is equal to doing it twice and then halving the result. Due to the associative law, the order of which you count the numbers is independent of the end result, so if you choose to add up in this order: 1+100+2+99+3+98+ ... + 99+2+100+1 , you would end up with (1+100)+(2+99)+..etc. or 100 paranthesis adding up to 101. The end result halved is 101*100/2 = 101*50 = 5050. In general notation: 1+..+N = N*(N+1)/2.

I've been doing pushups this month. I started with one on May 1st, two on the 2nd and so forth. Today I reached number 300 and on May 31st I'll add four to my regular program to reach en even ... how many :oP

Slight modifications to an image that drastically improve it (imho)

• Fixed the shadows in the corners (camera lens thingy called vignetting)
• Put some more red into the background
• Made water a little bluer
• Made shadows a little “lighter” on the baby elephant

The other day Christina and I swung by Frederiksberg Garden. Copenhagen Zoo borders this pretty piece of green in the center of Copenhagen, and the new elephant house is actually opened up  into the park (well, baring a moat, some electrical wiring and a 4-feet fence) which is great if you want to see the Elephants but just don’t feel like emptying your wallet to do so.

This old girl had a little fun spraying water at some of the birds that were poking around the balls of dung. I know – it’s common to attribute animals human traits - but I swear that big beast was grinning. And just look at the baby-heffalump here

Unfortunately I didn’t get to capture the head-first dive into the moat by the calf, but you can just see how much fun it’s having. The moat is pretty deep by the way, deep enough for the elephants to submerge fully. Which they seemed to enjoy doing.

It's almost official - my apartment is sold. The buyer has a 6-day period to reconsider the purchase, but on Thursday it's all decided. Not the best time to sell though  but rather that than having two rents to pay.
