In the Blink of Bird’s Eye, a Model for Quantum Navigation | Wired Science | Wired.com

European robins may maintain quantum entanglement in their eyes a full 20 microseconds longer than the best laboratory systems, say physicists investigating how birds may use quantum effects to “see” Earth’s magnetic field.

Quantum entanglement is a state where electrons are spatially separated, but able to affect one another. It’s been proposed that birds’ eyes contain entanglement-based compasses.

Compose with Fibonacci's Ratio for Phenomenal Photos

 

If you're looking for a way to draw more attention to the crucial elements in your photographic composition, the Fibonacci Ratio offers a way to direct your viewers eye to the critical parts of your photo.

Earlier this year we highlighted another great composition rule, the Rule of Thirds, in our guide to getting more out of your point and shoot camera. Digital Photography School takes an interesting look at another composition rule, Fibonnacci's Ratio. Often referred to as the "divine ratio" because of the numerous places it appears in the natural world—such as the spiral of Nautilus shell—it offers a way to guide your viewer's eye to the area of the photo you want them to focus on.

When applied to photography, this ratio can produce aesthetically pleasing compositions that can be magnets for the human sub-conscious. When you take the sweet spot of the Fibonnaci Ratio and recreate it four times into a grid, you get what looks to be a rule of thirds grid. However, upon closer inspection you will see that this grid is not an exact splitting of the frame into three pieces. Instead of a 3 piece grid that goes 1+1+1=frame, you get a grid that goes 1+.618+1=frame.

The photo above is one of their sample photos, showing how the ratio can yield a focus that guides the viewer right to the subject's face/eyes.

 

BBC News - Voyager near Solar System's edge

Media_httpnewsbbcimgc_ehpaf

Voyager 1, the most distant spacecraft from Earth, has reached a new milestone in its quest to leave the Solar System.

Now 17.4bn km (10.8bn miles) from home, the veteran probe has detected a distinct change in the flow of particles that surround it.

These particles, which emanate from the Sun, are no longer travelling outwards but are moving sideways.

It means Voyager must be very close to making the jump to interstellar space - the space between the stars.
