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.

This is our daily open thread — Watch the video over and over…

  1. I had a book on mathematics when I was a kid. It said if you start with a leaf stem on a plant and count the stems as you spiral upward until you reach another stem directly above the first one, you’ll have a Fibonacci number.

    There’s also a famous problem with rabbits that have Fibonacci numbers as the answer. Start with one pair of rabbits. After two months, the rabbits have their first pair of rabbit kids, then another pair each month after wards. As each pair of rabbits is born, the same pattern repeats – two months until the first pair of kids, then a new pair each month after. F(n) will give you the number of pairs of rabbits you have after each month.

    • Great idea! Funny the wingnuts never say a word about controlling the means of stopping all the deaths by gunfire because guns are a Constitutional “right”, but rant ceaselessly on the Constitutional right guaranteed women in the Roe v. Wade SCOTUS decision.

      “Yah butt guns’re man things and wimmin’re not men so . . .” etc.

      This country is rapidly becoming one of the most fucked up and screwy entities on the entire planet, motivated solely by hate, fear, greed, and the eternal quest for power of the few over the many.

      Fascism is like that, I guess.

  2. Brit Hume on FNS, about Kevin McCarthy’s admission that the Benghazi hearings were to attack Hillary: “It gives the Democrats a talking point…a shillelagh, really, that they can beat the Republicans on this over the head with, ad infinitum.”

  3. Fareed Zakaria on GPS: “If one looks back over the many American interventions around the globe, one factor looms large: When Washington allied with a local force that was capable and viewed as legitimate, it succeeded. But without such locals, all the outside effort, aid, firepower, and training can only do so much, whether in Afghanistan, Iraq or Syria. If Obama’s goal is a peaceful, stable, multi-sectarian democracy in Syria, then it requires a vast American commitment, on the scale of Iraq. If not, Washington has to accept reality and make some tough choices. The two big ones are whether to stop opposing Assad, and whether to accept that Syria will have to be partitioned.”

    Putin, on the other hand, can ally with a capable local force, in Assad. Better to let the Russians foot the bill on this one, and let Syria be their Iraq. If John McCain wants to help the Free Syrian Army, maybe he’s in the wrong country.

    • McGraw-Hill noticed Dean-Burren’s video and agreed to rewrite the text.
      “We believe we can do better,” the publisher wrote in a Facebook post. “To communicate these facts more clearly, we will update this caption to describe the arrival of African slaves in the U.S. as a forced migration and emphasize that their work was done as slave labor. These changes will be reflected in the digital version of the program immediately and will be included in the program’s next print run.”

      This is so damn wrong!
      The new page should be done immediately and distributed to be placed in books already printed.

  4. A few minutes ago on MTP, Trump praised the quick police response in killing the latest whackjob in Oregon. Difficulty: The whackjob committed suicide.

    • If it wasn’t for the gun ban on campus, if teachers and students had been armed, there would have been no problem (according to Fucker Carlson on Fox):

      The hosts of Fox & Friends asserted on Sunday that mass shootings could be prevented by banning “gun free zones” instead of passing the type gun safety laws that have worked in Australia.

      According to Fox News host Tucker Carlson, praised Donald Trump for blaming the Umpqua Community College shooting on campus gun bans.

      “When there’s a drunk driving accident, you don’t ban cars, you try to prevent drunk people from driving them,” Carlson opined. “The idea that taking guns away from the law abiding will make us safer is insane and childish.”

  5. Summerville High School: Police Arrest 4 Students After Discovering Shooting Plot at California School

    County Sheriff Jim Mele said the students confessed to the plot and told police they were going to “shoot and kill as many people as possible.” A list of targeted victims was found among the evidence.

    They’re juveniles so they won’t release their names. Screw that. If they’re ready to pull off mass murder then they’re not juveniles.

    • What and how the hell do they get these notion of randomly shooting any and all in the vicinity?

  7. Sunsets reward us with time to reflect on the day’s events. If the moment overtakes you, it may even cause you to ponder the future. Where is your favorite place in Yosemite for reflection?

  8. Trump: Mass Shootings Are Inevitable, And The People Who Commit Them Are ‘Geniuses’

    on Meet the Press, Trump echoed his opinion that mass shootings are inevitable, and added that the people who commit those crimes are “geniuses in a certain way.”
    “They happen to be intelligent,” he said. “And, you know, they can be sick as hell and they’re geniuses in a certain way. They are going to be able to break the system.”

    Trump’s own gun plan calls for lifting bans on semi-automatic weapons, a law permitting concealed carry nationwide, and no expanded background checks for gun purchases.

    What could go wrong? Trump is, definitely, a genius. In his own mind.

    • The man is dangerous when he attempts to think.
      Gives me nightmares knowing there are so many nuts that follow him.

  9. “We haven’t seen this level of rain in the low country in a thousand years,” Gov. Nikki Haley told reporters Sunday afternoon. “That’s how big this is.”

    Despite no record keeping, you just know she means ‘a thousand years’ literally. Unless there’s something in the Bible about rain in SC, I dunno. So build your Ark, Nikki.

  10. From Mr. N.S. Sherlock:

    Republican presidential frontrunner Donald Trump said Sunday the Middle East would be better off today if Moammar Kadafi and Saddam Hussein were still in power.
