Mobius Transformations video (A YouTube hit)

From our friend Andrée at meeyauw:

An informative and beautifully produced YouTube mathematics hit. There is a YouTube link, where you will find a link to the original source of the video. You can download the video to your own drive. You really should watch this, even if you don't like math (gasp).

Well, we at CatSynth of course love mathematics, and appreciated this video. It is about Möbius transformations, an important concept involving complex numbers and geometry. You can watch the video below:



RIP Oscar Peterson (1925-2007)

Well, we have one more influential musician to remember before the year ends. The great jazz pianist Oscar Peterson passed away on December 23:

Called the “Maharajah of the keyboard” by Duke Ellington, Oscar Peterson is considered to have been one of the greatest piano players in the history of jazz. He played to audiences worldwide in a career lasting more than 60 years.

While Stockhausen (whom we remembered on his death two weeks ago) was an inspiration for his composition, electronic innovations, and ideas about music, Peterson was all about performance and technique, and joy of playing jazz at a high level. As a young jazz pianist, I used Oscar Peterson's piano solos as practice. In particular, I remember playing the minor bluesy Roundalay, which was my successful audition piece for All State Jazz in New York. Certainly, I could never even attempt to match the actual solos at full speed.

You can get a sense of the real thing from this video:

We close with these comments from the CBC:

Renowned for his speed and virtuosity as a pianist, Peterson ? who was born in Montreal and later made Toronto his home ? made hundreds of recordings in his career, even after a stroke in 1993 disabled his left hand…

…”The world has lost the world's greatest jazz player,” Hazel McCallion, mayor of Mississauga and Peterson's friend, told CBC News on Monday afternoon.

UPDATE: You can read his obituary from Mississauga.

Weekend Cat Blogging and more: December morning

This Saturday morning, we see Luna enjoying a different window:

It was a very cold morning, with frost.

Frost isn't very common for this part of California, though we have had a lot of frosty mornings this December. Yes, it has been quite cold. Perfect for spending even more time on a favorite perch above the heater:

But we all know the best source of heat is curling up together for some cuddling and pets:

This of course brings us to the theme of this weekend's Bad Kitty Cats Festival of Chaos: family and friends. Being close to one's family, human or feline, is important, and for me what keeps me going during what is an otherwise “difficult” period. Friends, too. And we hope to hear from some of our friends this weekend…


Weekend Cat Blogging Holiday Edition is being hosted by Katie and our favorite Luna-look-alike Puddy. Puddy seems even more like Luna than usual (except for the hat).

The Bad Kitty Cats Festival of Chaos is being hosted by our friends Astrid, Kashim and Othello at Catboys Realm. As stated earlier, the theme this weekend is “friends or family,” and it looks like Othello is getting things started with a sibling tribute of his own.

The holiday edition of Carnival of the Cats will be hosted by Missy and KC at The Cat Blogosphere. And of course the Friday Ark is at the modulator.

Science, light and cats

A few scientific articles that made the popular press this weekend also piqued our interest here at CatSynth. They both involve electromagnetic phenomenon – which in our daily world is most commonly observed as light.

So here's a story about light and cats, or rather a cat engineered to glow in the dark:

South Korean scientists have cloned cats that glow red when exposed to ultraviolet rays, an achievement that could help develop cures for human genetic diseases, the Science and Technology Ministry said.

Three Turkish Angora cats were born in January and February through cloning with a gene that produces a red fluorescent protein that makes them glow in dark.

You can read the whole article here. It is quite interesting, though we at CatSynth are not so sure about genetically modified cat concept.

We now move from glow-in-the-dark cats to the field of quantum computing, in which quantum states of electrons are used to store computational values (much like semiconductors are used in conventional computers). From the folks at ZDNet Australia:

Researchers from the University of Queensland have taken a significant step in the quest to build a quantum computer, creating a light-based quantum circuit capable of basic calculations and moving quantum computing closer to a becoming a reality.

Theoretically, quantum computers leave even today's most powerful conventional supercomputers in the dust. It has also been long known that hypothetical large scale quantum computers could find the prime roots of large composite numbers, allowing them to “crack” modern data encryption.

This additional computing power is a result of the quantum bits, or “qubits”, upon which quantum computing is based. Qubits are special bits that use the quantum properties of subatomic particles to make calculations. Quantum computers take advantage of a special quantum property called “superposition”, allowing one quantum computer bit to act as many.

Pretty hard core, but those interested are encouraged to read the full article, and maybe a bit more about quantum computing.

Cats of course have a famous history in quantum physics as well…
