It's Just Business -- While often what folks say as they screw us over, in this case corporate interests are righteous. Perhaps marketing departments are actually becoming enlightened by 'big data' et. al?

Pleasantly surprised to see informed plain talk from politicians on this tech issue: “It’s impossible to build a back-door for just the good guys -- if somebody at the Genius Bar could figure it out, so could the nefarious folks in a van down by the river... That's the disconnect from what we hear from the FBI and the reality."

Of sourse campaign funding realities will cause many of these 'representatives' to vote for the TPP. That's still a fight we can win IMO, because we've all seen people power succeed in similar situations...

This game of so-called 'class warfare' will continue to swing in both directions. Greed and ethics will always struggle unless & until we reach a state of #EnlightenedSelfInterest. At this point though, WikiLeaks has proven that this particular emperor needs a brand-new tailor.

Back to Busics -- Time flies on a Greyhound / Trailways bus when you find an interesting fellow traveler to speak with. On shorter trips the comforts can help keep you entertained: AC power outlets, restrooms, and the reading lights & air vents are very reminiscent of a plane:

Rode a short-haul route round-trip to Portland, Oregon about a year ago, around 3 hours each way for USD $28 total. Views of the scenery were great, and I enjoyed some podcasts & music while keeping my phone charged. The experience was free of 'security theater,' and I'd gladly do it again without reservation, so to speak...

So it might be a decade or more before I'd even consider going to an airport for a commercial airline flight. My favorite 'spin' quote from the article: '...loss of all AC electrical power, which could result in loss of control of the aeroplane.'

The time has finally arrived. Periodically rebooting airplanes to make them usable over time.

How Might We Know? -- Brian clarifies a recent meme floating around the popular scientific press. Still interesting to wonder how we could wake up to the truth, if we really were asleep in #TheMatrix
The Universe is Still Not a Hologram

Tis the season for claims that the universe is a hologram again. Just to be clear, there’s no observational evidence that the universe is a hologram, and the latest research driving the sensational headlines doesn’t claim that there is. But there is some interesting theoretical work regarding the holographic principle that is worth discussing.

The holographic principle argues that the information contained within a region of space can be determined by the information at the surface that contains it. For example, imagine a road 10 miles long that is “contained” by a start line and a finish line. Suppose the speed limit on this road is 60 mph, and I want to determine if a car has been speeding. One way I could do this is to watch a car the whole length of the road, measuring its speed the whole time. But another way is to simply measure when a car crosses the start line and finish line. At a speed of 60 mph, a car travels a mile a minute, so if the time between start and finish is less than 10 minutes, I know the car was speeding. Mathematically, the space can be represented as a hologram of the surface that contains it. Unfortunately the term hologram invokes images of virtual reality and the idea that we’re living in the Matrix, which couldn’t be farther from the truth.

As a theoretical tool the holographic principle is useful because it is easier to do some calculations on a boundary than it is on the enclosed volume. One of the most popular uses of the principle is in string theory, through something known as the AdS/CFT correspondence, which uses the holographic principle to connect the strings of particle physics string theory with the geometry of general relativity. The AdS stands for anti-deSitter space, which is a non-flat model universe. Anti-deSitter space can’t be used as a model for the physical universe, because we know observationally that the universe is extremely flat.

It would be nice if there were a similar holographic correspondence for a flat universe model, but proving one has been difficult. Now a new paper has shown that the holographic principle can apply to flat space models, at least in some cases. The team looked at an aspect of quantum theory known as entanglement. If two objects such as electrons are entangled, they can be described in quantum theory as a single entity. Entanglement is one of the more strange aspects of quantum theory, and leads to some strange predictions about the universe, but has been experimentally validated. What the team found was that a calculation in standard quantum theory of a particular entanglement property dealing with entropy gave the same result when done using a holographic version. In other words, the standard and holographic versions are mathematically equivalent. They did these calculations in a model universe that’s flat, which demonstrates the holographic principle can work in flat space.

This is not a general proof, and it doesn’t show that the holographic principle does work for a flat universe like ours, only that it might when it comes to quantum systems. There’s a lot more work to do before anyone can say with certainty that there is a flat space version of AdS/CFT correspondence. And even then it won’t mean the universe is a hologram.

His Truthiness Will Set Us Free -- Nice to see honest folks, of many persuasions, finding common ground on this issue. Republicans join in of course, perhaps out of knee-jerk opposition.
Obama's dissembling and condescension about the "trade" deal -- in fact, a collection of corporate favors that will be terrible for most of us -- is reaching new depths.

Old Bones -- A #Caturday tag on a post about a Sea Otter?? Each time I've seen Eddy at the Zoo in Portland, he's looked remarkably like my old feline avatar here on G+. The resemblance to a cat, including whsikers & ears, is striking IRL:

Check out the short video in hig-res, and see whether you agree. Also learn there why Eddie plays basketball...

The pic of Theodore, my old avatar, is still available under Profile Photos. 'Ted' was young there, very frisky and agile. As an older kitty he spends a lot of time stretched out on his back, even when wrestling with his adpoted 'brother,' a Golden Retriever.

In Corina's OP you'll find that Sea Otters also often lie on their backs, floating, which really made the resemblance clear at first glance.
Sea Otters eat, sleep, hunt, mate, and give birth in the water. They also use rocks as tools to crack open mussels.

Sea otters often float at the water's surface, lying on their backs in a posture of serene repose. They sleep this way, often gathered in groups. Otters sometimes float in forests of kelp, or giant seaweed, in which they entangle themselves to provide anchorage in the swirling sea.

These aquatic otters do more than sleep while floating on their backs. They are often seen with a clam or mussel and a rock that has been deftly snared from the ocean floor. Otters will place the rock on their chests, and repeatedly smash the shellfish against it until it breaks open to reveal the tasty meal inside. They also dine on such aquatic creatures as sea urchins, crabs, squid, octopuses, and fish.

Sea otters are the only otters to give birth in the water. Mothers nurture their young while floating on their backs. They hold infants on their chests to nurse them, and quickly teach them to swim and hunt.

Are You 'Shocked, Shocked?' -- Tor fanboys have been ignoring the danger of #ExitNodes serving as fodder for government agencies and other crackers. Now this real-world case comes to light:

Perhaps security- and privacy-conscious folks will begin to seriously consider this built-in design weakness. We might also start to wonder, as I have for years, whether the U.S. Office of Naval Intelligence is motivated solely by the common good in developing and continuing to sponsor Tor?

Lo-Hype, High Promise -- Good news is that the term 'Fuel' is just a metaphor. So concerns about literally printing biofuels just come from an overactive B.S. Detector. The name does still qualify as hype IMO:

Also, pricing or availability have 'yet to be announced.' So let's hope for more details from the joint venture this spring, rather than the eternal #RealSoonNow ;->

If It Ain't Broken... -- The social model of disability: 'We need to change your environment to make your life better.' This improves conditions for everyone, including both the 'neurodiverse' and 'neurotypical.'

Barbershop Quartet -- Delayed getting haircuts as long as possible, as far back as I can remember. One reason may have been discomfort at the infinite reflections in the shop's mirrors:

#JoeTheBarber seemed Italian just like half the folks in the neighborhood. But when asked directly, he corrected me with the more precise term, 'Sicilian...'

It bothered me, as a kid, to be kept waiting while Joe waited on men who'd arrive after I did. Catching up on reading DC Comics only partially made up for that ;-|

The insanity of infinite reflections

This picture by +John Valentine shows a ball inside a mirrored spheroid... together with all its reflections! The real ball is at lower right.  The rest are reflections.  They form crazy patterns - the kind of thing mathematicians think about when they can't sleep at night.

This is like a picture I showed you earlier, made by +Refurio Anachro. But now the ball is lit from three directions with soft red, green, and blue lights, so we can see things more clearly.  The view simulates an ultra-wide-angle camera. 

This is just a low-resolution closeup of a much bigger and more detailed picture!  You can get other views here, along with a good discussion:

You can get a really big version here:

This is 16384 × 16384 pixels and about 16 megabytes.  If you know a nice way to display such a big image online, which makes it easy to zoom in on pieces, please try it!

Puzzle 1: what creates the black 'zone of invisibility', and the fractal hexagonal patterns near the zone of invisibility?

I don't really know the answer in detail - this could be a great math project.

I've watched a number of movies where the climactic final scene involves people fighting inside a hall of mirrors, where it's hard to tell who is real and who is a reflection.  Orson Welles' 1947 classic Lady from Shanghai may be the first - if you haven't seen that, you should definitely watch it.  Another that stands out is Bruce Lee's Enter the Dragon

Puzzle 2: what other movies or stories do you know involving this theme?

Happy Earth Day 2015

Today, April 22, 2015 is Earth Day's 45th anniversary.

Earth Day is an annual event, celebrated on April 22, on which day events worldwide are held to demonstrate support for environmental protection.
It was first celebrated in 1970, and is now coordinated globally by the Earth Day Network, and celebrated in more than 192 countries each year.

Go to Earth Day's website>>

I chose a sky view of Earth from Suomi NPP that we can see below>>

This composite image of southern Africa and the surrounding oceans was captured by six orbits of the NASA/NOAA Suomi National Polar-orbiting Partnership spacecraft on April 9, 2015, by the Visible Infrared Imaging Radiometer Suite (VIIRS) instrument.
Tropical Cyclone Joalane can be seen over the Indian Ocean.

Winds, tides and density differences constantly stir the oceans while phytoplankton continually grow and die. Orbiting radiometers such as VIIRS allows scientists to track this variability over time and contribute to better understanding of ocean processes that are beneficial to human survival on Earth. The image was created by the Ocean Biology Processing Group at NASA's Goddard Space Flight Center in Greenbelt, Maryland.
