Discover yourself -- Comment()
When we want to know who we are (or were), it is enough to search the web with Google. I run into my own posting from seven years ago while looking for something else. At first I didn't regognize the writing as my own. Was I at some point discussing things in the Usenet discussion group on mathematics? It seems to be so.

Who knows, a few years from now on it may be commonplace to use the web as part of your personal memory.

Hello, world -- Comment()
Check out ACM Hello World collection for examples of different programming languages. Sad to say that the Fortran example is based on the old standard:

PROGRAM HELLO DO 10, I=1,10 PRINT *,'Hello World' 10 CONTINUE STOP END

How would this look like in Fortran 95? Something like the following:

PROGRAM hello_world IMPLICIT NONE INTEGER :: i DO i = 1, 10 WRITE (*,*) 'Hello World' END DO END PROGRAM hello_world

If you know Finnish, check the Fortran 90/95 textbook, which is available in PDF format.

Worm's Use of Copper Could Point to Novel Material Designs: "...the marine bloodworm may help scientists design new materials that are hard and durable yet lightweight. [...] it represents the first instance of a copper biomineral discovered in a living organism. In addition, the way the element interacts with proteins within the worm could serve as a prototype for novel material design." [Scientific American]
