There is a story that a class of KLM stewardesses, first confronted with a computer mouse (I personally know a KLM stewardess who is quite familial with the animal variant, al least her cat is) tried to move them over the screen like a lightpen, a device predating the mouse.

Re: Then there is another problem...
Hb. Chem.& Phys. 53rd Ed., E41 gives the velocity of sound in m/s at 25+t°C as:
Water (distilled): 1496.7+2.4t
--> 37.5% ethanol, 62.5% water 1388+0t (estimated)
So Turing was right. Gin (and Vodka) are OK. Vermouth (16-18% ABV) won't work in a delay line.
Two weak spots
"You always perform a startup sequence of gestures to get into the control system before sending the real gesture commands. The startup squence (sic) could be relatively long so false positives become rare cases. Such a startup sequence can also serve as your personal password."
There is no way to see you entered the RIGHT startup sequence before you send the commands, in particular if you are not in the same room as the WiSee enabled Wi-Fi router.
"WiSee technology uses multiple antennas to focus on one user to detect the person's gesture."
There is no way to track a person.
Don't dig in the desert
" \"I hope more people find out about Alamogordo through this opportunity that we have to unearth the Atari games in the landfill,\" Alamogordo mayor Susie Galea said."
I thought Alamogordo was already worldfamous/notorious by the Pu239 from the Trinity test burried there.
From the Dutch law on firearms (Wet wapens en munitie, translated):
"Category I 7° other objects that can form a serious personal threat as indicated by Our Minister or that look like a weapon appropriate for threat or extortion."
So no need for a Liberator here, just print your Walther P5 in soap and paint it black.
BTW the Liberator seems as good as the gun that exploded and killed James II of Scotland at the siege of Roxburgh in 1460.
Re: I tried painting on an iPad - turned out to be load of Pollocks!
You should have sold the iPad at auction.
In November 2006, Pollock's No. 5, 1948 became the world's most expensive painting, when it was sold privately to an undisclosed buyer for the sum of $140,000,000.
The problem is mass production: in 1986 the price of a Canon PJ-1080A Colour Ink-Jet printer (Made in Japan) was 2644.18 Hfl., incl. 19% VAT (equivalent to 1199.88 Euro).
The serial number of my PJ-1080A is 801057, but I doubt whether 801057 printers were made. The resolution was only 85 dpi.
May be converting it to a 3D-printer is a nice hobby project.
Re: Bend light here and hey presto, your aircraft becomes a bird
The research paper mentioned describes calculations for a model working at a single microwave frequency ("wavelength 30mm at the frequency of 10 GHz."). No physical experiments were involved.
Jie Sun et al., "Large-scale nanophotonic phased array" http://www.nature.com/nature/journal/v493/n7431/full shows a more interesting innovation from MIT in Cambridge Mass. working at optical wavelengths.
Re: Ultra HD ≠ "4K" (3840×2160)
On IBC 2011 NHK (Japan Broadcasting Corporation) had a demo of their Super Hi-Vision system (7680x4350 pixels, intended horizontal viewing angle 100°).
I was impressed and thought I saw the future of TV.
However when I compared the image on the 85 inch LCD with the lady in front of the camera, I noticed that the colour reproduction, especially of skincolour, was very poor.
Re: 'rare and expensive helium'
"Hydrogen has twice the lifting capability [of helium] (H2 molecules are nearly twice the volume, and only half the mass)."
1) The lifting capacity is the difference between the density of air and the density of the lifting gas.
Hydrogen: 1.293-0.0899= 1.2031 kg/m3
Helium: 1.293-0.1785= 1.1145 kg/m3
(at 1 bar, 0° C)
2) The volume of H2 molecules is irrelevant. The number of molecules present in equal volumes of gases at the same temperature and pressure are equal (Avogadro's principle).
Re: three little words
"The traditional standard of clarity of a language is a cultural inheritance which should be carefully guarded. Language is one of the most important institutions of social life, and its clarity is a condition of its functioning as a means of rational communication." The open Society and its enemies by K.R. Popper (1945), Ch 12 note 30.
The gears of a "knijpkat" - literal translation: "squeezecat" - make a sound not unlike the purring of a cat (Felis Catus).
On top of my "knijpkat" is imprinted: "MADE IN HOLLAND - IMPORTE DE HOLLANDE - TYPE 7424-03 - 2.5 VOLT - 0.1 A" with the Philips logo, the one with double-cross on either side of the channel, in the middle.
Modern versions with 3 LEDs, a rechargable battery and a crank are available (Made in China). Their plastic gears make a softer sound than the 1940's "knijpkat" made of steel and pertinax.
The guard could be floored by the Taiwanese lady at 0:14. Every woman should be able to defend herself. My mother learned Ju-Jutsu during WW II and practised the ticks half a century later.

Re: A lot of hostility here

Josef Vissarionovich Djugashvili a.k.a. Stalin HAD a religion
after he lost his faith at the Tiflis seminary in 1896: Marxism.
He always has seen himself as special and deified himself
with unimaginable consequences.
