Comment Re:"Develops", "Solves" (Score 1) 100

I think a laser projected keyboard that projects onto the side of the forearm or wrist would make more sense.

Something like these--

coupled with the projector technology that was incorporated into some phones a few years back:

http://www.gizmochina.com/2012...

Basically, the smartwatch just beams a tiny 3 row keyboard onto the wearer's wrist/forearm whenever it detects that the wearer's hand is in the "typing zone". Then the wearer taps away on their arm, and the smartphone registers the input.

But that would probably introduce additional battery life reductions on an already cramped device.

Untrue.

There is nothing preventing photons of different wavelengths from being entangled, allowing one wavelength to expose an image, while another scans the subject-- As demonstrated by the above article. This is vastly different from normal photography.

Similarly, there shouldnt be any real reason why different polarizations couldnt be entangled.

A very sophisticated compositing scanner could be constructed that uses entanglement + interaction with a subject with simultaneous measurement to break the entanglement at the sensor. There is a great deal of benefit to having the exact same light hit many sensors.

Even in regular photography, you can get HDR this way.

Here's an example of such "Interesting" photography.

http://news.nationalgeographic...

Having detectors for the many different properties of the photon, rather than just "IS/isNOT entangled", (which is why there needs to be many CCDs with a single aperture), could reveal a wealth of information about a photographed object.

Comment Random musing (Score 0) 107

This is just random musing, but I would love to see a complex camera built using some of these entanglement properties.

Using entangled photon light sources and multiple CCDs with a single entry aperture and some beam splitters, (So the the multiple CCDs get the exact same entangled photons), I expect some very interesting photography would result.

I realize that would mean using a laser lightsource, making it unsuitable for photographing people (unless they shut their eyes), but I could definitely see such an instrument being constructed and used using conventional components.

Comment Google just pissy (Score 5, Informative) 107

Google is just in a snit that CyanogenMod is fantastically better than stock android, BECAUSE it gives power back to users.

For instance, the power to rescind permissions on installed apps, the ability to have finer control over CPU throttles, and of course, the removal of bunches of total horse-shit that gets bundled.

Google is more worried that CyanogenMod being a mainstream thing will affect their ability to have baked in adware out of the box, generating money for them. Not that CyanogenMod devices will fail to run 3rd party apps.

"Oh noes! Dont allow users to use fake geolocation! That will ruin our datamining operations! Oh no! Not our playstore advert shit too!? Did you REALLY just give users the ability to say "NO" to that app maker's blanket permissions requirement AFTER they said yes initially to let it install!? How will Facebook get its hentai tentacles into users' contact lists!? That removes the "Our way or the highway" tactic from the table!! AHHH!"

Seriously-- this is SOP for big companies that have "disruptive" competition-- Attempt to buy them out.

Google is probably pretty steamed at getting hand slapped right about now, which is why they are brandishing their oh-so-special google services apps like a cudgel now.

That's unfortunate.

While these devices will probably have nutritional ratings similar to most "gluten free" snack chips (that is to say, 0 calories per serving), they typically come with a significant amount of heavy metals baked right in.

Oh, and don't forget the arsenic.

They probably wont taste very good either.

MP3s have had metadata since the 90s, when the ID3 tag was introduced.

http://en.wikipedia.org/wiki/I...

All a knockoff player needs is a file system checksum initiated rescan+index routine to probe for new ID3 tags after the filesystem changes and the USB connection is removed.

Walks the whole filesystem, checks each MP3 file it finds for the ID3 tag, references it against a small internal index file to see if it has already been catalogued, then adds/remove entries as needed.

When the user wants to "browse by genre", it just queries this catalogue, and fetches file handles.

There is *A LOT* of data you can put into an ID3 tag, including whole jpegs of the album cover!

This whole shitfest has been solved for a long, LONG time.

Comment Re:Uses blackbody emission (Score 2) 110

True, however the steepness of the peak is relevant.

Compare the spectral footprint of sunlight at sea level:

Clicky

With the typical power curve of pure blackbody emissions:
Clicky

The latter one has a single peak. The former has a much "flatter", but also noisier distribution. One can optimize at the near infra-red band, where the blackbody emission peaks consistently, and harvest the vast majority of the emitted photons. Especially since this band is also very close to the innate emission/capture band of pure silicon.

This means that PV cells tailored for near-IR and IR capture will be WILDLY efficient with this setup.

Comment Re:Carnot efficiency (Score 1) 110

Not a heat engine.

This is a black body emission system.
http://en.wikipedia.org/wiki/B...

Basically, it is the result of the conservation of energy being employed. As an object heats up in a vacuum, it sheds the heat energy as increasingly more energetic photon emissions. Any substance that is not at absolute zero will emit blackbody photons. These are usually in the far infra-red spectral band, though under very high temperatures more energetic photons will be emitted. This is how your typical tungsten filament incandescent light bulb works.

This approach uses the specificity of the heated material to emit blackbody photons within a specific wavelength, regardless of the wavelengths of the light used to heat it up. However, it does not fix certain things:

1) Blackbody radiation is emitted from all sides of the emitter; it cannot be made directional. This means that the design that MIT has created, with the collector sandwiched against the emitter, will be at most 50% effective (When used with a light-source derived heat source). This is because some non-trivial portion of the re-emitted light will be beamed off the back of the device, where there is no collector to catch it!

2) To be a useful device, an enormous number of blackbody photons will have to be emitted. This means the emitter has to be bitching hot.

3) To be really efficient, the device must be as heavily insulated against thermal loss as possible. This means it wont be thin and light.

Comment Uses blackbody emission (Score 5, Interesting) 110

This system uses blackbody emission to re-radiate absorbed photons within a specific bandwidth, which can be selectively optimized for.

However, since it uses blackbody emission, it does not explicitly NEED light as the energy source. Any kind of heating will suffice. This is really just a very fancy means of converting entropic energy into something useful. Could be very useful when coupled with radio-isotope decay systems, for instance. (This, coupled with existing RTG tech, could produce more efficient RTGs)

Sadly, it requires that large numbers of useful photons be produced from the emitting blackbody source, which means it needs some pretty non-trivial temperatures. This isn't going to be something that is used in normal residential settings.

Comment Re:Baking Soda May Help! (Score 1) 140

This is true for "general" treatments. (Treatments applied to the whole body, EG-- "General Anesthetic") However, there are also local treatments that are more targeted that can change the environment locally.

Several such treatments exist. In the feild of cancer specifically, you have the various direct radiation treatments, the various nanoparticle+radiowave treatments, and of course, local excision treatments.

In the case of colon cancer, the inner wall of the colon has evoloved to handle some pretty extreme changes in pH, and also insane levels of salinity. Circumstances that if presented in the rest of the body would kill the patient in minutes. (If not seconds).

This tissue is also very thin, only a few millimeters thick.

The crime that the OP really has comitted is assuming that all cancers are interchangable as a general category. They arent.

In the case of colon cancer, a concentrated baking soda enema (or even a supository) would work to keep the ambient pH inside the colon quite low, and would be in direct or nearly direct contact with the cancer spreading in the colon wall at the same time. Healthy colon cells would be easily able to handle this environment, but diseased ones would not.

The major risk of complication comes from disruption of GI Flora from prolonged alterations of the pH in that environment (and from administration of probably not-very-sterile sodium bicarbonate solution directly introducing new microbial strains), and from the risk of possible impaction (if using a supository) or rupture (from overzealous enema use)

As long as the cancer has not yet metasticised, there is no real compelling reason not to couple such a clinically untested treatment like bicarbonate exposure along with a more well documented anti-cancer regimen, but some caveats apply. (If surgery was used to remove the cancer from the colon wall, then common sense applies. Dont use enemas unless directed to do so by your physician. You DONT want your colon to rupture, especially when you are immunosuppressed from having cancer.)

Just understand that not all cancers are created equally. Colorectal cancer is a very real, epidemic form of cancer. However, the ways you treat it are very different from how you would treat, eg, blood cell type cancers, or cancers in bone tissue. You dont need general application of treatment with some forms of cancer.
