Hologram Concerts

Hologram Concerts

There’s been a disturbance in the music world force. I pay an exorbitant ticket price, parking fees and sucker fees to see a live concert, but instead of real people performing, I get a hologram. As somebody who loves holograms, it saddens me to have to say this: using holograms to raise the dead or replace living musicians is total (real life) bulls*ht. Here are 7 bizarre hologram…

White light diffraction

White light diffraction

Diffraction effects depend on the wavelength of the light. Considering a single narrow slit with monochromatic light, light with wavelengths much larger than the slit will not be transmitted and light with wavelengths much shorter than the slit will be transmitted without significant diffraction effects…

Phones with Holograms

Phones with Holograms

In five years, cell phones will be able to produce holograms of friends and colleagues talking and moving in real time, IBM researchers say. In the mock-up photo provided by IBM, 3D video technology is used to create a hologram on a speakerphone. We see 3D [video] technology moving into the cell phone…

Two dimensional world

Two dimensional world

For all we know, the three dimensional world we see around us is really an illusion — one that’s actually in 2D. It’s a slightly unsettling idea, but it’s also one that physicists have been thinking about for some time. Unfortunately, until recently, a 2D universe wasn’t something we could verify. Now…

CD diffraction

CD diffraction

The information on a CD is stored on a very thin shiny spiral track. When light shines on these thin lines it is diffracted in all directions, the light from neighbouring lines interferes constructively when the sin of the angle=λ/d. This means that different colours of light are seen at different angles. This is what causes the coloured patterns that you might have seen. In this…

Hologram Keyboard iPhone 5

Hologram Keyboard iPhone 5

Just look at those holographic images. ralphardi/YouTube Screenshot: Chris Matyszczyk/CNET New Yorkers are over-excitable. So when they see folks already lined up to buy the iPhone 5, they come over extra-giddy. Who, therefore, could blame Fox 5 New York from rushing out to interview the sad, money-grabbing self-publicists who are already adorning the Apple Cube, waiting for the…

Hologram Design Software

Hologram Design Software

A new development in virtual reality could change the way product designers work by enabling them to create physical objects out of holograms in the air. A collaboration between Microsoft’s hologram headset HoloLens and design software Autodesk Fusion 360 means that designers will be able to design 3D products by working on full size holograms. Possibilities for the “every day designer”…

Jem and the Holograms movie

Jem and the Holograms movie

Jem and the Holograms Yet even in this first announcement, Chu made no bones about his take on the Jem storyline, referring to it as a modern day reinvention of the beloved property. As jarring as the reinvention word might sound to fans who grew up on Jem, Chu appeared to soothe fears with his first request: That fans submit videos specifically about why they loved the original…

Diffraction grating interference pattern

Diffraction grating interference pattern

Dispersion Although we talk about an index of refraction for a particular material, that is really an average value. The index of refraction actually depends on the frequency of light (or, equivalently, the wavelength). For visible light, light of different colors means light of different wavelength. Red light has a wavelength of about 700 nm, while violet, at the other end of the…
