Science unlocks one of Da Vinci’s secrets

Mona Lisa XRF.

The Mona Lisa has been and will likely always be one of the most mesmerizing examples of fine art known to man. For centuries, scholars have marveled at the detail, the absence of brushstrokes, the subtle shadows, and of course, the source of her wry smile.

Science has unlocked the secret (or part of the secret) behind at least one of those attributes by using X-ray fluorescence to determine the composition of oils and paints Da Vinci used for Mona Lisa’s baffling skin tone and shadow work. From the original story at CNN:

[Researchers] found that some layers were as thin as one or two micrometers and that these layers increased in thickness to 30 to 40 micrometers in darker parts of the painting. A micrometer is one thousandth of one millimeter.

They believe this characterizes a technique of painting that uses a glaze, or very thin layer, to build up shadows in the face.

The manner in which Da Vinci painted flesh, “his softened transitions,” were pioneering work in Italy at the end of the 15th century, say the researchers, and were linked to his creativity and his research to obtain new paint formulations.

While this is certainly a victory for science, it also adds to the mystery behind Da Vinci and his technique. Micrometer-thin, virtually undetectable brush strokes made at the turn of the 16th century? I would love an explanation for that.

You know you’re a lush when…

You buy a wine glass that can hold an entire bottle of wine. I’m not real sure why they even try to market this thing. Couldn’t the ad just say, “Hey, it’s better than drinking straight from the bottle,” or, “Classier than a milkshake straw.” Instead, whoever made this ridiculous goblet went about the marketing like so:
full-bottle-goblet

Yeah, I bet that lady can just casually balance a full bottle of wine in one hand while she reads. If anything, this glass will make you drink faster just so you don’t pull a muscle in your arm.

Netflix sneaks past Hulu

Hulu vs Netflix.

Netflix and Hulu started dueling for streaming dominance some time ago, and for the most part Hulu has been winning that fight. It looks like Netflix may have taken a leg up, though, and I’m hoping it stays that way.

According to comScore, Netflix barely edged past Hulu in unique visitors this past month. I’ve really enjoyed Netflix streaming service, but the company needs to get up to current seasons if it wants to give Hulu a serious run for it. One of my favorite shows, Party Down (which none of you were watching, which is why it got the ax – shame on you), had current season streaming from Netflix and I watched it every week. It’s a fantastic alternative to a cable subscription, which tends to just fill my living room with a lot of noise.

Hulu’s trying to keep the top spot with Hulu+, granting access to full current seasons and some legacy episodes for a fee. The company’s ad structure could really hold it back, especially when competing with the Netflix platform.

Vuzix Wrap 310: Great concept, poor execution

vuzix_wrap_310

For as far as we’ve come in technological advances over the years, one thing that still hasn’t been perfected is video eyewear. I’m not exactly sure why anyone would want to have to wear something over their eyes in order to watch a movie when we have things like iPhones, iPads and portable DVD players, but Vuzix – one of the companies at the forefront of video eyewear – clearly believes it’s the future of on-the-go entertainment. But while it’s a great idea in concept, it’s hard to get over just how goofy you look wearing them. Though the latest line from Vuzix isn’t quite Virtual Boy-big – they look more like a pair of sunglasses that you’d buy at the gas station – they’re still a little clunky for something best used during travel.

Vuzix currently has three different models out on the market – the Wrap 230, 310 and 920 – and although the latter version features the biggest screen and best resolution of the bunch, it’s not worth the higher price tag. The Wrap 310 will work just fine for most users, as it offers a home theater experience akin to watching a 55-inch TV from about 10 feet away. The glasses themselves are actually pretty comfortable, but after you’ve plugged in a pair of headphones, the remote control unit, and your iPhone, it suddenly becomes very awkward to carry around. Still, Vuzix has made them as user-friendly as possible. It takes only a few minutes to set up, and the nosepiece is easily adjustable so that the unit can be shared between people of all sizes.

Where the Wrap 310 really falters, however, is in image quality. Though it supposedly boasts two “high-resolution” 428×480 LCD widescreen displays, it has a screen door effect that severely lowers the overall quality – especially when compared to watching a movie on your iPhone or PC. Unfortunately, that makes its appeal even lower, since a majority of the product’s target audience will probably be tech heads who are obsessed with image quality. That’s not to say that you can’t enjoy watching a movie on the Wrap 310 – the picture is decent enough, and you can personalize video settings like brightness, contrast and color saturation via an onscreen menu – but it doesn’t look as good as it probably should.

Playing video games while wearing the glasses is a little surreal, but it can be a bit dizzying (much like virtual reality), and ultimately isn’t worth it considering most people have big screen HDTVs in their homes these days. Sunlight also creeps through unless you’re in complete darkness, and though Vuzix sells a bulky rubber lightshield for $15, it’s something that really should have been included in the package. Of course, when you take into account that one of the main selling points of the Wrap 310 is its stylish, compact design, I can understand why they wouldn’t want to.

There are a few positives to the Wrap 310 – like offering enough room to wear glasses underneath or providing the option to manually adjust the focus for prescription-free viewing – but it’s simply not enough to warrant the suggested $249.99 price tag. Though you can find them for much cheaper on Amazon, it’s an amenity that most people just don’t need. I loved being able to lay around while watching a movie, and it would be great to have a little extra privacy on a plane trip, but until Vuzix can offer a comparable moviegoing experience, it’s probably best to wait.

There’s a Facebook script to see who deleted you

QQ please.There are a lot of things I really loathe about Facebook. While it is a good place to connect and share things with my actual friends, there’s always the strange undercurrent of lurkers – people I haven’t seen or talked to in as much as a decade trying to keep up with me by watching status updates and the like.

One such person sent me an invitation to look at a page on Facebook titled “Find out who deleted you.” This may have been around for awhile, but that doesn’t make it any less ridiculous. If you need a script to tell you when you’ve been removed from a “friend’s” page, you probably shouldn’t have friended them in the first place. And what do you plan to do now that you know? Rage at them? Send them a nasty note? Track them down?

As great as all of our tools for connectivity are, there is a threshold of overconnect for me.
