But the slow decay in radiation intensity from a tabletop pulsar would make possible extremely long-range transmitters, giving far-off space probes an energy-efficient way to beam information back to earth.
The Indian Ocean was displayed as a large sea surrounded by land, while many of his measurements of longitude (something that was very hard to measure accurately until John Harrison's timepiece won a famous competition in the 18th century) were way off beam.

His disquisition on light, aimed at disproving Newton, was way off-beam.
Unlike previous one-way demonstrations, the LCDD uses an infrared beam -- in the same way that many land-based fiber networks do -- that can be received on Earth by one of three telescopes located in Mexico, California or Spain.
By bombarding the fossils with an infrared synchrotron beam a noninvasive way of analyzing a material's internal chemistry the scientists said they detected molecular traces of an organic protein inside the mineralized bones.
Since there's no physical interface on the device to configure WiFi, the company's developed Blinkup, a way to enter SSID and password information on any iOS and Android smartphone and beam it to the Electric Imp's light sensor by rapidly pulsing the handset's screen on and off.

Since B and C have the same quantum states, that means C also has the same quantum state as A. If A and B are different, they will come out of the beam-splitter in one of three different places, depending on exactly which way they are different.
She is working on focusing the transmitted beam into a much smaller area, so that less energy is lost along its way.
But they could find no way through and their frustration resulted in lapses in discipline, which Sinfield punished despite complaining about a laser beam being shone into his eyes.
Working with local net-makers, Devon's beam-trawler fishermen voluntarily trialled their own designs, stitching the net panels together in a different way to allow the mesh to stay open, thereby letting smaller fish escape.
