Perception puzzles, Visual Perception, Optical illusions and Paradoxes
This page illustrates that our visual perception cannot always be trusted. The components of an object can distort the perception of the complete object. Our mind is the final arbiter of truth. Most optical illusions are the result of 1) incongruent design elements at opposite ends of parallel lines, 2) influence of background patterns on the overall design, 3) adjustment of our perception at the boundaries of areas of high contrast, 4) afterimages resulting from eye movements or from kinetic displays, or 5) inability to interpret the spatial structure of an object from the context provided by the picture.

Acer Aspire One 6-cell vs. 3-cell battery comparison » unitstep.net
Since my initial unboxing of the Acer Aspire One, I’ve managed to get my hands on a 6-cell version for testing. I was interested in seeing what this unit was like, considering that most complaints stemmed from the inadequate battery life of the 3-cell version, which was also evident to me. Here are some comparison pictures to help you decide whether the extra bulk is worth the additional run time.

Bronze Age history off by 100 years
Provided Trenchmaster Vronwy Hankey and foreman Antonis Zidianakis excavate storage jars from the Minoan settlement Myrtos-Pyrgos. The jars were analyzed in the Cornell study using radiocarbon analyses. Separated in history by 100 years, the seafaring Minoans of Crete and the mercantile Canaanites of northern Egypt and the Levant (a large area of the Middle East) at the eastern end of the Mediterranean were never considered trading partners at the start of the Late Bronze Age. Until now. Cultural links between the Aegean and Near Eastern civilizations will have to be reconsidered: A new Cornell University radiocarbon study of tree rings and seeds shows that the Santorini (or Thera) volcanic eruption, a central event in Aegean prehistory, occurred about 100 years earlier than previously thought.
OSX Leopard 10.5.5 On A PC
Please see update at end of post! In previous posts I showed you how to install Tiger and Leopard on your boring PC and cut its chains of slavery to Windows operating systems. Installing Tiger involved quite a bit of work, and may have taken someone with advanced knowledge of computer software an entire weekend to perfect. Drivers were hard to come by, and it was largely luck of the draw if you were able to get your particular hardware to work with Tiger.

No Acid Burn for Naked Mole Rats
The naked mole rat, native to East Africa, has no shortage of quirky biological features: it resides underground in near darkness, lacks hair, lives for more than 2 decades, and doesn't develop cancer. Now, another one of its unusual traits has been explained—its inability to feel pain from acid. The adaptation allows the mole rats to thrive in their communal tunnels, where acid levels rise because excess carbon dioxide builds up as the animals exhale. "Understanding more about how pain pathways work is critical to developing new ways to treat pain," says the lead author of the new study, neuroscientist Ewan St. John Smith of the Max Delbrück Center for Molecular Medicine in Germany. Smith and his colleagues previously discovered that when they injected small amounts of acid into the paw of a naked mole rat, the animals showed no response.
