Sunday Roast: Mesmerize me, Fibonacci

I found this on facebook, which found it on The San Francisco Globe.  Never heard of it before, but I haven’t heard of everything yet.  Heh.

I watched this video until my eyeballs went googley, and then I watched it some more the next day.  Here’s the info:

John Edmark is an inventor, designer and artist who teaches design at Stanford University in Palo Alto, CA. One of his latest creations is a series of 3D-printed sculptures designed with proportions corresponding to the Fibonacci Sequence. When Edmark’s sculptures are spun at just the right frequency under a strobe light, a rather magical effect occurs: the sculptures seem to be animated or alive! The rotation speed is set to match the strobe flashes such that every time the sculpture rotates 137.5º, there is one corresponding flash from the strobe light.

These masterful illusions are the result of a marriage between art and mathematics. Fibonacci’s Sequence is defined as a recurrent relationship that can be expressed as  F_n = F_{n-1} + F_{n-2}…  where the first two digits of the sequence can be defined as F_1=1, and F_2=1. What this means is that the sequence starts with two 1’s, and each following digit is determined by adding together the previous two. Therefore, Fibonacci’s Sequence begins: {1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89…} etc.

What does all that mean?  No seriously, I’m asking — what does all that mean?  I dunno, but it creates some pretty cool designs and amazingly mesmerizing video.  Or a dude in Palo Alto has way too much time on his hands — could be that.

Sunday Roast: Summer Solstice

Happy Summer Solstice, all y’all?  Heh, all I know is that it’s supposed to be the day of the year with the longest daylight hours.  I won’t say it’s the longest day of the year, because, as we all know, that is a rather subjective concept.

Anyhoo, enjoy this lovely video of Alaska during summer solstice.

Sunday Roast: Robert Greenwald’s “Koch Brothers Exposed”

I know it’s an hour long, but please watch this video.  It’s only ONE HOUR of your life.

It’s important for all of us to know how the despicable Koch brothers have woven their tentacles throughout this country, like a deadly cancer.

They have a very specific ideology, and they don’t give a shit if you subscribe to it or not.  Given their way, we will all feel the toxic Koch boot on our necks, sooner or later, and we can’t fight them if we don’t know what they’re about.

Sunday Roast: What if…

What if hate hadn’t killed the best of us?

What if fear hadn’t made us hateful?

What if ignorance hadn’t made us fearful?

What if poverty, hunger, and a lack of education hadn’t left so many of us ignorant?

What if greed hadn’t left so many of us hungry, uneducated, and in poverty?

What if wanting too much hadn’t made us greedy?

What if forgetting what was “enough” hadn’t made us want more than our share?

What if we all had enough?
