10:14 AM | Enabling students in a digital age: Charlie Reisinger at TEDxLancaster – YouTube
The power of Free and Open Source software at work. Why would you give a child a powerful machine, then not give them the permission to learn and understand how it all works? Allowing students to ‘look under the hood’ of their computers, to change, modify, and create at will, is liberating imagination and knowledge…Read more →

8:00 AM | The Last Word
August 11-15, 2014 While the Discovery Channel attempted to terrify you with fanciful tales about extinct monster sharks with six-inch-long teeth, LWON focused on smaller, cuddlier, but still deadly beasts. Yes, it’s Snark Week at LWON. “Remember,” Erik says, “just because something is fluffy and adorable doesn’t mean it’s not secretly plotting to kill you in terrible and gruesome ways.” […]

“Es ist immer angenehm, über strenge Lösungen einfacher Form zu verfügen.” (It is always pleasant to have exact solutions in simple form at your disposal.) -Karl Schwarzschild The Universe is a vast and complex place, full of a diversity of structure from the smallest scales to the largest. And yet, by many accounts, it’s a…

The High Court of Justice of England and Wales has ruled that Amazon’s UK subsidiary infringed the trademarks of cosmetic maker Lush Retail Ltd. by directing website customers to other products when they searched for the Lush brand.

8:21 PM | Help Kids Learn Astronomy
It’s a World-wide Science In July I wrote about the Astronomers Without Borders Indiegogo campaign called “Telescopes to Tanzania”.  The group’s campaign can use a boost and I’m happy to urge you to consider supporting it. AWB spreads the news about astronomy throughout the world, and there’s NO reason why kids in Tanzania shouldn’t get […]

4:00 PM | The Passing of T’Pring.
In an bygone era, it was difficult for ethnically challenged actors (ie. non-white) to get roles in television and the movies.  Then along comes Star Trek, and everything is busted wide open.  Russians (Checkov), Asians (Sulu), African American (Uhura) and a wide variety of aliens came into the living room once a week for three … Continue reading →

12:00 PM | No, Google Moon Doesn’t Show an Alien Loitering on the Moon
This is Part N in what is apparently a never-ending series of articles that have a title that starts with “No, … .” You can find more in the related posts at the bottom of this post. [UPDATE (Aug 15, 2014 at 16:30 UTC): ARRRRG! I was soooo close. It turns out this object is actually a bit of dirt or debris that was in the lens of the camera that took it. This was in fact my first thought, but when I saw that the images used in Google Moon were from Clementine, I dismissed […]

I mean, LOLCats was severely dumb and stupid but nobody’s doing that any more, right? I hope.   AG’s cat (though a little badly drawn) is thoroughly in the spirit of Snark Week and has the attitude nailed:  if you think soft cuddly Nature loves you and is your friend, you’re not paying close enough […]

7:25 AM | Così "parlano" i cavalli
Più che i nitriti, i cavalli usano gli occhi e le orecchie per comunicare tra li loro. Si capiscono insomma ad uno sguardo o ad un'alzata di orecchio, senza bisogno di parlare. E' questa la conclusione di uno studio pubblicato su Current Biology, importante promemoria (semmai ne servisse) del fatto che altre specie comunicano in modi anche molto diversi da quelli utilizzati dagli esseri umani. “Il nostro studio è il primo ad esaminare un possibile mezzo di […]

6:00 PM | The Faces of Ultraviolet
I spend a lot of time thinking about how narrowly we see the Universe. Our eyes perceive the narrowest slice of the electromagnetic spectrum, the huge range of flavor lights comes in. Radio waves, infrared, ultraviolet, X-rays, gamma rays—they make visible light, from blue to red, seem hopelessly parochial. You don’t need to go far outside what the eye can detect to learn a lot about the world around you. Photographer Thomas Leveritt knew this and decided to find out for himself […]
