Why Time Flies By As You Get Older 252

Posted by kdawson on Tuesday February 02, 2010 @11:03PM from the like-a-banana dept.

Ant notes a piece up on WBUR Boston addressing theories to explain the universal human experience that time seems to pass faster as you get older. Here's the 9-minute audio (MP3). Several explanations are tried out: that brains lay down more information for novel experiences; that the "clock" for nerve impulses in aging brains runs slower; and that each interval of time represents a diminishing fraction of life as we age.

Nmap 5.20 Released 36

Posted by Soulskill on Saturday January 23, 2010 @11:32AM from the more-and-better dept.

ruphus13 writes "Nmap has a new release out, and it's a major one. It includes a GUI front-end called Zenmap, and, according to the post, 'Network admins will no doubt be excited to learn that Nmap is now ready to identify Snow Leopard systems, Android Linux smartphones, and Chumbies, among other OSes that Nmap can now identify. This release also brings an additional 31 Nmap Scripting Engine scripts, bringing the total collection up to 80 pre-written scripts for Nmap. The scripts include X11 access checks to see if X.org on a system allows remote access, a script to retrieve and print an SSL certificate, and a script designed to see whether a host is serving malware. Nmap also comes with netcat and Ndiff. Source code and binaries are available from the Nmap site, including RPMs for x86 and x86_64 systems, and binaries for Windows and Mac OS X. '"

15-Year-Old Student Discovers New Pulsar 103

Posted by ScuttleMonkey on Friday January 22, 2010 @05:37PM from the sky-isn't-the-limit dept.

For the second time in as many years, a student has made a discovery while participating in the Pulsar Search Collaboratory (PSC), a joint program between the National Radio Astronomy Observatory and West Virginia University designed to get students and teachers involved in analyzing data from the Robert C. Byrd Green Bank Telescope (GBT). This time it was high school sophomore Shay Bloxton, who discovered a brand new pulsar. "For Bloxton, the pulsar discovery may be only her first in a scientific career. 'Participating in the PSC has definitely encouraged me to pursue my dream of being an astrophysicist,' she said, adding that she hopes to attend West Virginia University to study astrophysics. Late last year, another West Virginia student, from South Harrison High School, Lucas Bolyard, discovered a pulsar-like object called a rotating radio transient. His discovery also came through participation in the PSC."

"interactive whiteboards are not just "gee whiz" toys"

I think the money would be better spent on a tablet PC along with the projector - for significantly less money you get something that can do the same things, does not blind those who are using it, allows even short people to reach the top of the board and is much more flexible.

When was the last time you saw someone take an Interactive whiteboard on a field trip?

It also worries me that Interactive Whiteboards lead naturally to teacher centred lessons - I thought the idea was to move away from the "sage on the stage" to the "guide on the side".

"gee whiz" indeed.
