Cat Goes to the Train Station to Meet Its Owner Each Evening

</p> <p><a href="http://video.heraldsun.com.au/2131780176/Feline-trainspotter">Video: Feline trainspotter</a></p> <p>

Graeme, a cat in Melbourne, Australia, walks to the train station with its owner in the morning and then goes off to play (and probably lots of sleep, it is a cat) and then returns in time to meet its owner at the train station after the work day.

The pampered cat cannot get enough of attention, with scores of regulars calling him by name as they stop for a chat and give him a pat on the head. Safety conscious, the sociable moggie is meticulous about using the subway to cross to the city-bound platform, rather than take a dangerous short cut across the tracks.

When the evening peak comes around, Graeme puts on an encore performance, arriving at the opposite platform in time to greet owner Nicole Weinrich as she returns home from work. “He always seems to know which train carriage I am on and will be sitting there behind the yellow line when the doors open, because he is all about safety,” Ms Weinrich said.
…
But sometimes Graeme can take his desire to be close to his fans a bit too far – he has been known to jump on the train and get off a station or two later. “He doesn’t do it often, but we do worry about that,” Ms Weinrich said.

She said Graeme, believed to be about 12, had roughed it on the street before being saved from the RSPCA’s “death row” six years ago, so his love of people is tempered by his survival instincts.

Swarmanoid: Cooperative Robot Networks

Very cool cooperation between robots. It seems more and more research is going on in cooperative robotics. It would seem this would let us have specialized robots for various tasks instead of having to have robots that can do everything (which is very complex and difficult). Plus cooperating robots are just cool. See the Swarmanoid project web site and the overarching Swarmbot site. I look forward to what these scientists and engineers can create for us.

How Algorithms Shape our World

Our modern world is influenced greatly by algorithms. As computing power allowed incredibly complex calculation we have taken advantage of that and used algorithms to find solutions to our desires. Great things are done but we also find ourselves getting into trouble occasionally as we develop these algorithm.

Cambrian Explosion Song

via Smithsonian’s Surprising Science:

What does a music teacher do when he ends up teaching science? He teaches about evolution and the geologic timeline with music, of course, and that’s what Canadian elementary school teacher John Palmer did. He originally played “Cambrian Explosion” as a rock/hip hop creation in class but has since recorded an acoustic version. (The trio is called Brighter Lights, Thicker Glasses and consists of Palmer on the guitar/vocals, Michael Dunn on the dobro and Brian Samuels [from UBC civil engineering department] on the cello.)

The video was filmed in the Beaty Biodiversity Museum (Canada) atrium with the blue whale exhibit in the background.

Amazing Webcast of the Aurora Borealis

The Aurora from Terje Sorgjerd on Vimeo.

Norwegian landscape photographer Terje Sorgjerd spent a week capturing one of the biggest aurora borealis shows in recent years. He shot the video in and around Kirkenes and Pas National Park bordering Russia at temperatures around -25 Celsius.

Aurora are caused by the collision of charged particles and the Earth’s magnetic field. Aurora Borealis is Latin for northern lights. An aurora is usually observed at night and typically occurs in the ionosphere. The lights are commonly visible between 60 and 72 degrees north and south latitudes, which place them in a ring just within the Arctic and Antarctic polar circles.

Auroras result from emissions of photons in the Earth’s upper atmosphere, above 80 km (50 miles), from ionized nitrogen atoms regaining an electron, and oxygen and nitrogen atoms returning from an excited state to ground state. They are ionized or excited by the collision of solar wind particles being funneled down and accelerated along the Earth’s magnetic field lines; excitation energy is lost by the emission of a photon of light, or by collision with another atom or molecule. Oxygen emissions give off a green or reddish hue, depending on the amount of energy. Nitrogen emissions give off a blue (if the atom regains and electron after it has been ionized) or red hue (if returning to the ground state from an excited state).

Auroras are associated with the solar wind, a flow of ions continuously flowing outward from the Sun. The Earth’s magnetic field traps these particles, many of which travel toward the poles where they are accelerated toward Earth. Collisions between these ions and atmospheric atoms and molecules cause energy releases in the form of auroras appearing in large circles around the poles. Auroras are more frequent and brighter during the intense phase of the solar cycle when coronal mass ejections increase the intensity of the solar wind.

Friday Fun: Audio Engagement Ring

Fun, an engagement ring that plays a 20 second audio clip “Shelina, I’ll love you forever. Marry Me!…Shelina, I’ll love you forever. Marry Me!” made by artist and inventor Luke Jerram.

100 lbf/inÂ² of pressure was required to cut the silver ring, using a vibrating diamond stylus. The ring is also a homage to Thomas Edison who made the first sound recording machine – the phonograph in 1877.

Using the ring, I proposed to Shelina in a hot air balloon over Bristol in 2005. We’ve since got married and had 2 children Maya and Nico.

Much better than marketing driven expensive diamonds, in my opinion.

Getting Closer to a Universal Translator

I wrote the following to my friend yesterday

> for those that haven’t picked up English, pretty soon Google translate
> will do a decent enough job of imitating a universal translator

And today my brother tweeted this video:

Ok, not quite a universal translator yet, but we are moving in the right direction.

Housecat Adopts Bobcat Kittens

3 bobcat kittens we rescued by Big Cat rescue.

Introductions like these can be very scary because the mother cat can be overly protective of her own kittens and fatally strike out at the new comers. President, Jamie Veronica, has had a considerable amount of experience in this area though and had taken every precaution to make sure it went as well as it possibly could. Bobbi turned out to be a dream come true for three little orphaned bobcats though. She immediately pulled them in close to nurse and began to bathe them. The little bobcat babies were so startled that they hissed at her!

She ignored their resistance and just kept on loving on them. Once they figured out that this strange smelling “bobcat” mom had the real deal to offer at her breasts, they were in love too.
