ICE CAN KILL YOU. SCIENCE CAN SAVE YOU.

DE-ICING A WING

 

ICE

Ice can build up on airplane wings. When this happens, the airplane loses lift. When an airplane loses lift, it doesn’t fly so good.

What if were possible to make metal immune to icing?  What if this immune-to-icing metal  could also be used in compressors so that air conditioners and heat pumps and refrigerators and freezers didn’t ice up?   Actually? If you add it all up, the money saved, the energy that wouldn’t be wasted, the air fatalities that wouldn’t  happen – this would make the world a better place.

So.

Guess what?

Two women at a college in Cambridge, Massachusetts developed  (ACS Nano) a treatment for metal that repels ice. Ice doesn’t have a chance. Anything – even “incipient condensation droplets” –  slides right off. Dr. Joanna Aizenberg and Dr. Amy Smith Berylson call the product SLIPS. The marketing department may call it something catchier. Whatever. The point is, this is a great idea. Potentially, this has lots of uses. It even  works for the blades of wind turbines which, if they get iced up, also lose “lift” and become inefficient.

The downside?   I sure can’t find one.

BRAINS ALL OVER THE PLACE

Posted by on Thursday, 14 June, 2012

DEVICES SMARTEN UP

 

WORLD WIDE BRAIN?

It started simple. With the Palm Pilot.

You could do a few functions – notes, calendar, some calculations, that kind of thing. There was a modem, 512 kilobytes of memory, and a monochrome screen. The Palm was just a glimmer of what was coming. Microsoft got into it with it Microsoft Mobile devices and Apple caught the wave with its IPod and IPhone. And Google threw Android phones at the wall; and was amazed at how many of them stuck. Which pissed off Microsoft so it made a new version of its own phone.

Palm Pilot

The race was on.

They’ve gone all out. Gargantuan marketing budgets, out-of-this-world technical innovation, manufacturing prowess, and skyscrapers full of patent trolls trying to imagine and lock up every conceivable variation of computer and communications technology out into the distant, distant future.

It’s like the race for the atom bomb. Only that was scary. This is fun, right? Cute little I-things. Pictures of lovable green robots.

The primary field of battle was raw intelligence. The problem: improving the understanding of “natural language” for text input or speech input. Google wanted to make it easier to search. Not long ago, if you made a typo in a long search string, you got the wrong stuff. Or nothing at all. Google realized it had millions of users. “Why not,” it thought ” take advantage of  what we can learn from their efforts to ‘understand’ speech?” If all that data was used right, maybe it would be the thing that would finally bring artificial intelligence into the mainstream.

Did it work? You know it did. When you type in Sicence Ain’t So Bad, what happens? It knows what you were trying to say, right?

IRIS

The competition between the giants – Microsoft, Apple, Google took many forms. Last year, Apple released IRIS, its voice system. The BS may have gotten out a little ahead of its functionality and some users are so mad they’re suing. But you can see what those SteveJobsians are up to. An alter ego in your pocket  Could Google afford to ignore IRIS?  Hardly. Besides, Google, already had its own voice technology stuff. So it just cranked harder. Wait’ll you see the Galaxy S3!

THE WORLDWIDE BRAIN THING

There’s nothing wrong with healthy competition.

Or even unhealthy obsession.

It makes our devices better and better, right? But before phones went crazy with this stuff, the world of artificial intelligence was esoteric . It was inhabited by professor types. Now that Apple/Google/Microsoft are throwing everything at it to stay ahead,  and now that the behavior of hundreds of millions of phone and tablet users is being mined to deepen the understanding of language,  I gotta ask my usual question. Does ANYBODY have a CLUE where all this is leading?

How long will it be till – hype aside – we really can interact naturally with our devices? Till they acquire human-like characteristics but without human-like limitations such as fatigue, hunger, and lust?

It won’t be long. I CAN tell you THAT!

AND

Because the devices  are in our pockets, the technology is ALREADY deployed. It’s just a matter of picking out which apps to use. Plus the devices are connected from here to hell, right? – 3G, 4G, Wifi, Bluetooth, NFC – you name it. So your brilliant phone will connect to your not-too-shabby car and, voila!, machines with unnerving human qualities. Machines we may come to regret. Robots, medical devices, all kinds of things that operate independently and without much need for us at all.

LIKE IT OR NOT

We are on the threshold of something very big. I don’t exactly know what it will mean. Nobody does.

Please don’t worry. I’ll keep you informed as the good/bad things become more obvious, as we race beside the future trying to keep up with it.

PLANETS SKITTERING ALL OVER THE PLACE

What Planet Are YOU ON?

What planet are YOU from?

AN ABUNDANCE OF PLANETS

What planet are you from? This is something people ask me all the time. Would they ask it if I didn’t have a propeller on my beanie?

The thing is, the list of planets  is growing.

Dramatically.

According to Roger D. Blandford (Director of the Kavli Institute for Particle Astrophysics and Cosmology at Stanford University), there could be as many as 4,000,000,000,000,000 (4 quadrillion) stars in the Milky Way. or about 10,000 planets for each sun.

Isn’t that 9,992 more than anybody’s noticed for our own sun/star? If they’re out there, where, really, could they be that they’ve gone undiscovered all this time?

Dr. Blanford’s referring to a fairly new category of planets called “rogue planets” which, unlike Mars and Venus and Earth and other civilized rocks, don’t orbit a star but, instead, roguishly follow their own independent paths. According to this theory, when galaxies collide, they disrupt the orbits of planets, sending them off hither. And thither. And yon.

No longer orbiting a star, they would have tended to escape the notice of astronomers and planet hunting satellites such as Kepler. But if life had already become established on such planets before they got bumped out of orbit, life would have a good chance of surviving its new sunless condition  (and THAT is according to  Dimitar D. Sasselov of Harvard).

Well. Let’s be careful.

There’s some evidence in this stuff. Which makes for good science. And there’s some speculation in this stuff. Which makes for fun science. Mister ScienceAintSoBad would be remiss if he didn’t dispense a pinch of salt with this study for now.

More to come.

Maybe.
