A hologram expert and professor of theoretical physics at Dalhousie sets the record straight on the hologram-like images used in CNN’s election coverage in this CBC article:
The CNN anchors were not really speaking to three-dimensional projected images, but rather empty space, Kreuzer said. The images were simply added to what viewers saw on their screens at home, in much the same way computer-generated special effects are added to movies.
Kreuzer said the images were tomograms, which are images that are captured from all sides, reconstructed by computers, then displayed on screen.
Holograms, on the other hand, are projected into space.
Will.I.Am was unavailable for comment.
Dal Prof Jason Brown’s latest discovery is getting him some blogger buzz. He spent 6 months decoding the elusive opening sound of the Beatles’ “A Hard Day’s Night” by “disassembling the sampled amplitudes into the original frequencies”.
In other words, he isolated all the sounds from the opening chord and figured out each note being played. He drew conclusions on what instrument played what note based on general Beatles knowledge – George Harrison played a 12 string so he knew which notes belonged to him. After determining which Beatle played which note, he was left with 5 notes unaccounted for. He explains that these must have been George Martin playing five piano notes in addition to the other instruments.
This guy should be on CSI.
