Reflections of Earth improvements including new lasers

[ABQ]

That was a laser ball, not a spherical motorised LCD screen. IllumiNations pyro product is almost laughable compared to today (before the recent cuts)

The current show is technically far more advanced. But is still rooted in late 90s tech.

Laser ball, sounds retro awesome! Do any of your own videos have footage of this thing in action?

Just one question, is ROE going away in 2016 as has been rumored by Jim Hill? I didn't put much stock in it until reading that Martin mentioned some changes besides New lasers coming to the show.

RoE has been rumored to be replaced since 2010, which was its original end-of-life. If someone keeps saying it will be replaced, they will eventually be right. Although remember how long Star Tours took? It will happen when it happens.

I know it was rumored to be replaced sooner than 2010. I remember watching it on the last night of my 2009 trip and bidding farewell to it, for I was sure IllumiNations the Skydance would be running by the next trip I made. ROE is a show that just needs modifications from time to time. You can't replace the greatest story ever told .

Nevertheless, I've watched ROE about a dozen times since 2000 and it gets more unimpressive every time. very meh.

Our luck they will install CO2 lasers

Nobody got this? I might be a nerd but CO2 lasers are invisible.

Simple science says that humidity & dust and other small particles in the air have a greater impact on how well a laser is seen with the naked eye, assuming its wavelength is within the visible spectrum.

A Carbon Dixoide laser produces a beam of light on the infared spectrum. So no, its not visible with the naked eye.

Simple science says humidity is invisible. Mist and fog are condensed water droplets and scatter laser light. Humidity is water vapor, a gas that does not scatter light.

Okay. So. When its humid as hell out, it causes the smoke to just hang in the air.

More precisely, an atmospheric inversion suppresses convection. That traps both humid air and smoke laden air. So, the same mechanism that traps the smoke traps the humidity. Both are symptoms of the same causality.

Am I back in 1988 waiting to watch The Wall at the planetarium on Florida Southern's campus in Lakeland? How did laser shows become associated with planetariums? Do planetariums still do this to raise money? Did Disney realize lots of lasers could be had for cheap due to lack of laser shows at aforementioned planetariums? More incredibly thought provoking questions to come.

Boy does this bring back memories. Laser Floyd in the Fels Planetarium at the Franklin Institute.

(I'm just kidding of course ) Even though I think it is the best show on property, I know IllumiNations isn't everyone's cup of tea.

No worries, agreed that it's not everyones thing. It's alright, but in my eyes it's Disney's (all of Disney) least visually impressive and chorographed fireworks show. It doesn't grab you like many of the others do.

 

[TimeTrip]

I wasn't really a fan of RoE until I watched it from the showcase plaza. The right viewing location (with conditions conducive to seeing the lasers) makes a huge difference.

So what causes Mie scattering.

 

[DisneyGentleman]

So what causes Mie scattering.

Mie scattering occurs when light interacts with particles of a size of the order of the wavelength of light. That can be water droplets, smoke particles and the like. Fog is made up of water droplets, not water vapor. As I said, water vapor is a gas and is invisible. For example, the light from the lasers used at illuminations has a wavelength anywhere from a half to 1 micrometer. So it scatters from particles in that size range.

I know what you said, I just happen to disagree with your statement that vapour doesnt impact the travel / colour of light.

 

[DisneyGentleman]

Well then you should have said Rayleigh scattering, which is the scattering of light by particles (or molecules) much smaller that the wavelength of light.

Compared to Mie scattering, it is a substantially smaller effect, and negligible in laser light shows where smoke, dust and fog dominate.

It's akin to ignoring relativistic effects in Newtonian physics.

how does that relate to you saying that vapour doesnt affect light?

 

[DisneyGentleman]

First off, I didn't say that. Secondly, as I explained, in the context of a laser light show it's a negligible effect.

Physics is all about ignoring negligible effects in the context of a particular problem.
