across analog audiences carriers digital fairly frustrated low power replaced spread switch
Lamentably, alien audiences may be frustrated by the switch to digital television. That's because the transmitter power for DTV is fairly evenly spread across the spectrum. The spikiness is gone, and from afar, the attention-grabbing squeals of analog television's carriers have been replaced by DTV's smooth, low hiss.
advance digital good hardware hugely pictures point rapid sets technical tube tv
There will be an end point to how good TV pictures can get. The boob tube has hugely benefited from the rapid advance of digital electronics. Consequently, the strategy for hardware has changed. In the old days, sets had to be as simple as Elmer Fudd to keep them inexpensive. All the technical 'smarts' were at the transmitter end.
both inevitably job money others possible spend victim ways
While I have always thought that the motivation for looking for E.T. was both self-evident and patently worthy, it's possible that I'm a victim of my own job description. Others don't inevitably agree. Some will opine that there are better ways to spend the money.
ball boiling endlessly hot internal patterns shakes thanks
Of course, Sol is a big ball of hot gas, but one that - thanks to its endlessly boiling innards - shakes and vibrates. By studying patterns on the Sun's surface, astronomers can learn much about Sol's internal construction.
liquid twice water
One of the jovian moons, Europa, is coated with twice as much liquid water as is sloshing around our planet.
banal european filled folk nor quaint towns
'Battleship' is not a film that Francois Truffaut would have made. Nor would any of those other namby-pamby European directors. Nope, this picture eschews that Continental obsession with small stories, set in quaint towns filled with pockmarked folk doing their banal things.
afternoon century expert facts field result science
Look, science is hard, it has a reputation of being hard, and the facts are, it is hard, and that's the result of 400 years of science, right? I mean, in the 18th century, in the 18th century you could become an expert on any field of science in an afternoon by going to a library, if you could find the library, right?
billions except familiar happening
We can no better imagine what will be happening on the moon 500 years from now than Columbus could imagine contemporary Manhattan. Except to say that it will be a place familiar to billions of people.
allen alone array telescope
We can never prove that we're alone in the universe. But the Allen Telescope Array could prove that we're not.
amplifier basement expired graduated high lack magazine nearly people
When I graduated high school, nearly a half-million people subscribed to 'Popular Electronics' magazine. Soldering up some radio or hi-fi amplifier on the basement workbench was not just a personal passion - a lot of young people were doing the same. The magazine expired in 1999 for lack of interest.
currently life might planets plate rich scarcely sports venus
Planets that don't currently sport plate tectonics, such as Venus and Mars, are scarcely habitable. Tectonics might be a requirement of any world that aspires to a rich diversity of life.
brains build good inadequate might perhaps
Sure, our three-pound brains might be inadequate to understand the universe. But perhaps they're just good enough to build something that can.
almost dinosaurs interested kids might science
I think a lot of kids are interested in two science subjects: dinosaurs and aliens. The reason is almost genetic; we're hard-wired to be interested in things that might be a little dangerous.
home intelligence might stay
I think there's a lot of intelligence out there, but that's just my guess. Question is: Are they peaceable or hostile? You could say that the peaceable ones are just going to stay at home and play with their Nintendos, so if you do meet any of them, they might be hostile.
