was trying to figure out how the early television work... found this novelty youtube.
(anybody notice that NBC is "broadcasting" corporation? what happen if there is no such thing as "broad" cast anymore? )
The first practical iconoscope was constructed in 1931 by Sanford Essig, when he accidentally left one silvered mica sheet in the oven too long. Upon examination with a microscope, he noticed that the silver layer had broken up into a myriad of tiny isolated silver globules. [18] He also noticed that: the tiny dimension of the silver droplets would enhance the image resolution of the iconoscope by a quantum leap.[19] As head of television development at Radio Corporation of America (RCA), Zworykin submitted a patent application in November 1931, and it was issued in 1935.[1] Nevertheless, Zworykin's team was not the only engineering group working on devices that use a charge stage plate. In 1932, Tedham and McGee under the supervision of Shoenberg" href="http://en.wikipedia.org/wiki/Isaac_Shoenberg">Isaac Shoenberg applied for a patent for a new device they dubbed "the emitron", a 405-line broadcasting service employing the emitron began at studios in Palace" href="http://en.wikipedia.org/wiki/Alexandra_Palace">Alexandra Palace in 1936, and a patent was issued in the USA in 1937.[20] One year latter, in 1933, Farnsworth also applied for a patent for a device that use a charge storage plate and a low-velocity electron scanning beam, a patent was issued in 1937,[21] but Farnsworth did not know that the low-velocity scanning beam must land perpendicular to the target and he never actually built such a tube.[22][23]
IARA LEE: Yes, I think the miscalculation was that the Israelis thought, by jamming our satellite system, the world would not have any access to information. And they didn’t know that we had a backup system that was able to transmit live some of the events. And obviously it was dark in the middle of the ocean, so they thought they had it all taken care, as far as like no information would come out. They would be the only ones holding the information, because they were obviously filming. And we were hundreds of people, so some of us did manage to get, you know, photographs and video footage out. And today we are showing raw, uncensored footage, and everybody can take the clue. And we’ll make it available to the world for investigations.
New bugatti is almost out. This puppy has twice the power of average Formula 1 car engine, 20% more than previous model and probably gobble up enough gas to power a jumbo jet before adding another 2 degrees to global warming.
But it's a sexy car. and fortunately nobody can afford it, not even a hedge fund bankster.
The new Veyron 16.4 Super Sport comes with four enlarged turbochargers and bigger intercoolers that have been used to boost the power of the 16-cylinder engine to a total of 1200 HP and 1,500 NM of torque, the chassis has been extensively redesigned to maintain safety at extreme speeds – thanks to a slightly raised main-spring travel, stronger stabilizers, and new shock absorbers with a complex architecture originally developed for racing cars. Thesupercar has entered the Guinness Book of Records with an average top speed of 431 km/h (267 mph). The first five units will be sold as limited "World Record Editions" and will feature a special black exposed carbon and orange finish.
Must see people. timeline of all nuclear test up till 1998.
here’s an animated recapitulation of the world’s nuclear tests since 1945. Even with every month reduced to a second, it takes several minutes to gain momentum; from the end of the 1950s through the end of the 1980s, however, the whole thing becomes rather bewildering and about as depressing as tiny beeps and flickers of light can be.
A few random observations:
I can’t imagine most Americans are aware that the US conducted more nuclear tests than every other nation combined from 1945-1998. For whatever these figures are worth, the number of Soviet tests never eclipsed more than 70 percent of the US total. By the mid-1970s, when Team B was yodeling about a “window of vulnerability” in the US defense strategy, the US had conducted nearly twice the number of tests as their chief rival.
The British apparently conducted several nuclear tests in the US. I’ve since learned that there were nine such events from 1983-1991, all apparently in connection to the Trident project. Didn’t know that.
The most interesting period, in my view, takes place from the end of 1958 through September 1961. Nothing happens throughout 1959; France sets off a handful of bombs from early 1960 through the spring of 1961; then the Soviets go absolutely apeshit in September of that year, and things don’t really calm down again until the early 1990s. In this video, the erratic incidence of US and Soviet tests in the 1950s looks and sounds like a conversation. Afterwards, it’s an incoherent frenzy.
I didn't know we had done nuclear tests in the US, but it doesn't surprise me much.
We (the Brits) had to develop our nuclear bomb independently, well without any official help or support of the US at least, which I always thought bizarre as a number of key scientists (and spied for the USSR) were British during the US development programme. I feel the use of US test sites was a bit of an olive branch after that exclusion.
I'm not saying our exclusion from the findings of the original test was good or bad in the end, just that we weren't happy about it at the time.
On a bit of a side note (I wrote a thesis on 50s nuclear secrets) - it is interesting that up until the late 30s, all "nuclear" experiments were scientifically reported and peer reviewed - and the Russians kept this purely academic stance for a few years after the US started making a secret of it - most likely as they saw the power of the weapon first.
It is actually surprisingly easy to make a hydrogen bomb (ie. in the style of fat man or little boy) if you have the right materials with today's technology which is a little disconcerting. The major obstacle they found back then was making the implosion to be regular - which is relatively trivial with modern technology.
my first thought was, imagine the amount of uranium used for these silly activities. How much electricity can be generated from all that? decades of free electricity for everybody in the planet. Why am I still paying electricity, etc... My cynic mind says, well...somebody finally figure that part out and quickly start banning anything nuclear to prevent collapse of electricity price.
I think the same thing will happen to renewable energy once the price hit "near zero" eg. who needs utility companies anymore. I am going off grid. All of a sudden we are going to hear, how renewable is bad for everybody.
This is the first thing we've ever done which can properly be described as a music video, I think, rather than just a live recording. It was all done by the band themselves, and recorded using VHS for some inexplicable reason.
Hey, they should combine this with Segway self balancing controler. I bet it's going to be the biggest hit in personal watercraft ever. (too bad, I can't find the creator of this cool toy.)
