What if the Moon was a Disco Ball?

That’s no moon…

The large mirror-tiles are 150km squared, and the small ones are 100km squared.
They are all 10 km thick with glass (with an IOR of 1.56)
There are 3012 mirrored tiles

When as near as the ISS, the Earth surface to disco-ball-moon surface distance is 420 km or so The orbital period in relation to the earth is realistic, about a 2.1 hour period.

When the disco moon is in low orbit, each reflection of the sun as a caustic is effectively a tiny sun, although you can never reflect enough light to get above the temperature of the surface of the sun (about 6000 degrees).

Since the sunlight is going through glass first, glass will in general filter out a lot of the UV, so your caustics shouldn’t reflect too much UV. The projection of a mirror-tile is larger than the projection of the sun when seen from low altitude. .

when seen from far away the tile is smaller than the sun, and hence the caustic isn’t as bright . Basically the disco tiles are glass with a silvered backing. Some of the light will not penetrate the glass, and will be simply reflected off the first surface of the glass, This reflection strength increases as the angle of incidence approaches 90, generally referred to as a Fresnel reflection.. or rather the strength follows that equation. This reflected light will generally be full spectrum

The center of the giant flat mirror is orbiting at a distance of 2157.4 Km above the Surface of the earth, It’s diameter is 3474.8 km (same as the moon), It’s orbital period would be longer than the disco moon simply because it has less mass. But in this video it has the same orbital period as in the moon.

The actual mass of the giant mirror is absurd.. it’s way over­-engineered.. if a real one were to be built it wouldn’t have huge thick rims, it would more likely resemble a girder work, with Mylar films. Not huge death star like mirror with towers, and strobe lights (and a strange lack of solar panels)


Scott Belsky: What Are You Willing to Be Bad At?

In our careers and in our work, we can only get a few things right, so we need to choose what we focus on purposefully. More importantly, we need to choose things that are different from our peers. This is our competitive advantage and it is what can propel us to success.

In this 99U talk, Behance co-founder Scott Belsky shares how companies like Apple and Southwest Airlines use this strategy to ensure long term success. But finding your competitive advantage is only step one, the world changes quickly, and just as fast as you find your niche, you should be looking for another one

Top 5 Guest Couch Gags on The Simpsons

Here’s a selection of the best Simpson’s couch gag titles designed and animated by outside artists.

The so-called Simpsons ‘couch gag’ has gone down in television history as one of the most instantly-recognizable, near-immortal title sequences. The opening sequence, although seemingly timeless and familiar, actually features a range of unique twists in almost every single episode.

The couch gag made its first appearance in the show’s second episode (Bart The Genius – which first aired way back in January 14th 1990, in case you were wondering) and with more than 500 episodes spanning nearly a quarter of a century, the Simpsons team have had plenty of chances to play with that famous introduction. As a result, in more recent seasons, the couch gags have tended to become increasingly surreal and outlandish.

There have been some notable examples over the years: the 525th episode ‘WHAT ANIMATED WOMEN WANT’saw Homer channel the-one-who-knocks, Heisenberg, in a glorious tribute to AMC’s series Breaking Bad, whilst 2001′s ‘HOM?’ featured a cameo by none other than one of Groening’s other famous creations, Futurama’s Fry.

With over 500 episodes under their belt, Simpsons-creator Matt Groening has on occasion handed the reins to a number of artists and filmmakers, allowing them to unleash their creativity and produce their own unique spin on that famous sequence. In this Watch the Titles takeover of SUBMARINE CHANNEL’S TOP 5 series, we take a look at some of the best.
