Canadian Mars Weather Station

A neat post about the Mars mission (with links) from an unexpected source.

Here is a neat Google Tech Talk video about a 3D live motion video camera (blogged two years ago) that uses LIDAR. I wonder if we are talking about the same LIDAR technology as the one used in Mars?

Mandelbrot chats with Antonelli

A wonderful chat between Benoit Mandelbrot (father of fractal geometry) and Paola Antonelli (senior curator of Architecture and Design at The Museum of Modern Art, wrote her thesis on "Fractal Architecture").

Love this exchange (emphasis added),

BM: Well, it is very encouraging for me, because I'm an old man and, as I always mention at some point, I never made up my mind who I really was, which allowed me to spend my life on many things. So what you're telling me is that I can just relax, because I won't have to decide!

PA: I don't know. You're very responsible for what goes on right now. I don't think you can relax any time soon!

BM: Well, yes, but at least I won't have to become a specialist, because everybody is going to become a generalist.

Here is a beautiful video excerpt of the chat. (very well done and wonderfully shot. simply beautiful. and great to see Mandelbrot in person in a video chat. very cool.)

P.S. Have a look at MoMA's "Design and the Elastic Mind" exhibition which Antonelli curates. Very cool and neat.

Richard Florida @ Google & Banff

I was really lucky to watch a CBC National video report and “discovered” Richard Florida tonight. (smile) I am going to pay attention to Rich’s ideas and I have subscribed to his blog. Check out his latest book - “Who’s Your City?: How the Creative Economy Is Making Where to Live the Most Important Decision of Your Life.”

Here is a video of Rich interviewed by George on The Hour.

The following is an hour long video of Rich speaking at Google, NYC.

And if you are really keen and have nothing better to do (smile), then check out another hour long video of Rich speaking at Google, Headquater in CA (essentially the same speech but with a different set of Q&A starting at 48:45).

P.S. On a personal note, Rich reminds me of some of the great U of Toronto professors that I had. Great job in bringing Rich to Toronto. And I am looking forward to listening to Rich live at Banff World TV Festival.

P.P.S. Here is one of Rich’s recent blog post on Jane Jacobs.

P.P.P.S. I wonder if Rich gets some money from this BMW ad? (smile) By the way, I think I actually first read about Rich here in this UT magazine article.

Seeing Hungry, Mood & Money, Bad Belly Fat

Saw these three interesting science news. Enjoy.

*******

Seeing Hungry

Why does food look more appealing when you are hungry? Scientists are finding that the same chemical in your stomach that causes hunger also changes how your brain perceives food, as this ScienCentral News video explains.

*******

Mood and Money

Feeling sad and bad about ourselves is not only unpleasant — it can also be hard on our wallets. Psychology researchers have found that these emotions can cost you three times more for the same item than being in a better mood, as this ScienCentral News video reports.

*******

Bad Belly Fat

Scientists are finding more about how that bulge around your belly is more harmful than the pounds you may have elsewhere on your body. As this ScienCentral News video reports, belly fat may cause blockages in the arteries, and the finding could lead to better drugs to protect against heart disease.

Space technologies stay in Canada (for now)

Hot off the press from Globe and Mail (April 10, 2 AM EST) "Ottawa rejects space firm's sale to U.S.". (Note: also see my earlier blog entry about this sale and a link to a legal opinion.)

OTTAWA — The federal government has said no to selling Canada's leading space company to U.S. interests, concluding that the deal would not be in the best interests of the country, The Globe and Mail has learned.

Industry Minister Jim Prentice made the decision to issue an initial rejection of the deal on Tuesday, when he wrote a letter to the potential buyer, Alliant Techsystems Inc. of Edina, Minn., that said the takeover of MDA Corp. would not provide a “net benefit” to Canada.

Under Canada's investment-review law, the company has 30 days to make new arguments to the minister, and Mr. Prentice must then confirm his rejection. But Mr. Prentice's move signals his intention to take the unprecedented step of blocking a major corporate takeover, in an issue that has been fraught with controversy as opponents argued that the sale of MDA could impair Canadian sovereignty.

A spokesman for Mr. Prentice, Bill Rodgers, confirmed Wednesday that the note had been sent, but he was unable to provide further details. When contacted by The Globe and Mail Wednesday night, Alliant officials responded with a two-sentence statement that indicated that they are not willing to declare the deal dead. [...]

The proposed sale of MDA Corp.'s Information Systems Unit has raised nationalist sentiment and fears that Canada could lose control of the data from Radarsat-2 in a dispute over Arctic sovereignty. [K: I agree the Radarsat-2 data has an important role in our national interest and won't trust any US companies (which has to follow US government directives in case of national security related issues). At the same time, I reject the unfair negative implication associated with using words like "nationalist sentiment".] Alliant, also called ATK, is a U.S. weapons and space contractor. The systems unit is responsible for most of MDA's operations and 1,900 employees. [...]

Some of the staunchest criticisms came from within the Conservative Party. Tory MP Art Hanger voiced sharp concerns, and Conservatives on the Commons industry committee treated the sale with skepticism.

One Conservative MP, speaking on condition he not be named, said the sale had raised a surprising backlash among Canadians, who saw it as a point of pride being peddled to the United States – which might possibly use it against Canada's claim to Arctic waters.

I think Minister Prentice did the right thing here in rejecting the sale.

Update: See report by CBC (with video report) and Reuters.

Canadarm stays Canadian - for 30 more days

Vancouver-based MacDonald, Dettwiler and Associates Ltd. is an amazing world class company. I know from personal experience as I worked there for a few years in the early part of my career. So it was sad to see negative news of MDA planning to sell its Information Systems and Geospatial Services business (including technical teams and know how that built the iconic Canadarm, the newly launched Dextre, and the Radarsat 2 satellite) to Alliant Techsystems (an advanced weapon and space systems company).

Here are some news about the recent delay and an interesting and seems valid legal opinion from Rideau Institute,

When asked about this potential MDA divisional sale in Calgary recently, the well respected Senator Roméo Dallaire answered that it will be worst than the sale of the Canadian Avro Arrow. Here is an excerpt from the Arrow Wikipedia entry,

Following the Canadian government's cancellation of the Avro Arrow project in 1959, CF-105 Chief Aerodynamicist Jim Chamberlin led a team of 25 engineers to NASA's Space Task Group to become lead engineers, program managers, and heads of engineering in NASA's manned space programs—Projects Mercury, Gemini and Apollo. This team would eventually grow to 32 Avro engineers and technicians, and become emblematic of what many Canadians viewed as a "brain drain" to the US. Many other engineers, including Jim Floyd (whose design studies at Hawker Siddeley (Avro Aircraft's UK parent) on the HSA.1000 SST design studies were ultimately influential in the design of the Concorde[20]) found work abroad in either the UK or the United States.

Amazing Landing as Wing Hit Runway

I can't believe my eyes when I saw this UK Sun report and video (longer and better video) and AP report and video of a Germany Lufthansa flight's (carrying 131 passengers) wing grazing the runway as it attempted to land amid gusting wind. They were so lucky.

Many people and news media are calling the pilot "hero" as the plane's wing grazed the runway and almost crashed.

Now, I do have question about the first and second landings. Note that I am not a trained pilot and it is probably unfair to second-guess the pilot without full details of the conditions at the time. So I might be quite wrong in the following.

With respect to the first landing, I wander was the plane already blown off course before it got dangerously close to the ground? As the plane looked quite unstable and wobbly based on the poorly angled video. If the wind condition was that bad, maybe a more experienced pilot would have abort the landing earlier and execute a missed approach (see this FAA Decision Makers Guide or other similar international equivalent guide) instead of trying to land the plane? (note 1)

With respect to the second landing, was the pilot worried about the structural integrity of the wing after it grazed the runway and wanted to get the plane on the ground as soon as possible? If thats not the case and since the runway was still in poor condition to land, I wander if the polit has thought about flying to the destination alternate aerodrome (alternate airport) for safety reason? Standard operating procedure should have allowed for enough fuel on the plane to fly to the alternate and not risk the passengers' lives in trying to land in unsafe condition.

note 1: Have you ever wondered why when a plane lands, it always seem to be at maximum power? Well, the reason is just in case the plane can't land and have to execute a missed approach and to fly up again. And to do that, the engine has to be at maximum power, capable of taking off and fly around. Something I remember from a Air Traffic Control training course years ago.

Cancer Chip

From ScienCentral (with video),

Thanks to new microfluidics and nanotechnology, cancer doctors may be able to design custom therapies for patients by analyzing just a teaspoon of their blood. Researchers from Massachusetts General Hospital’s Center for Engineering Medicine and its Cancer Center have now shown that they can capture the rare cancer cells shed by tumors into the bloodstream using a new high-tech chip the size of a credit card. Counting and analyzing these wandering tumor cells could mean better early cancer detection and an improved method for monitoring whether treatments are working.

Fran Allen - first female Turing Award winner

Quoting her Wikipedia entry,

Frances Elizabeth "Fran" Allen (born 1932) is an American computer scientist and pioneer in the field of optimizing compilers. Her achievements include seminal work in compilers, code optimization, and parallelization. She was the first female IBM Fellow. In 2006, she became the first female to win the Turing Award.

Here is a link to her 2006 Turing Award Lecture (streaming .mov file) which I quite enjoy.

Self-healing rubber not afraid of cut

From BBC (with video),

A material that is able to self-repair even when it is sliced in two has been invented by French researchers.

The as-yet-unnamed material - a form of artificial rubber - is made from vegetable oil and a component of urine.

The substance, described in the journal Nature, produces surfaces when cut that retain a strong chemical attraction to each other.

Pieces of the material join together again as if never parted without the need for glue or a special treatment.
