Well, "social science", at least.

Well, "social science", at least. The thing is, most of these are questions from Western culture, and really they may either be the "wrong" questions, or culturally loaded. It might not matter in the end if there is an after life or not, provided you make an effort in this one.

Also of course, if say we all live in an "ancestor simulation", then things like numbers and afterlife's might just be part of the substrate, the program running it. It may not matter what the answers are also, because the important this is actually the questioning.

An inside look at the Google Brain team

For the past few months, we've had NY Times Magazine reporter Gideon Lewis-Kraus visit the Google Brain team several times and hang out with us for a few days at a time, with an eye towards writing an article about how our research team operates and what we're working on. We gave him pretty open access to our building, the people in the team, many of our meetings, etc., and over the course of several visits, he decided to focus his story on the origins of the Brain team, and on our in-progress collaboration with the Google Translate team to replace the old phrase-based translation system with a neural machine translation system (essentially part of the article is a behind-the-scenes look at how the scientific work in https://arxiv.org/abs/1609.08144 and https://arxiv.org/abs/1611.04558 came about).

This long article is the result of his visits and synthesis of what he learned. Gideon, I think the article turned out really well!

UPDATE:
I flicked switch at the back OFF and then ONE, and pressed the "On button" on the front again, and it booted! However, that switch is part of the power supply, so I think my diagnosis is still correct. Time to backup while I can, and move the stuff on the server to another PC.

Triple Pendulum Control

A few years ago Dr. Tobias Glück from Technische Universität Wien, found that along with his mathematical insights, computers and numerical methods were now fast enough to swing-up and balance a pendulum, on a pendulum, on pendulum on a sliding rail under computer control.

IEEE CSS Video Clip Contest 2014 Submission

Triple Pendulum on a Cart (YT ~1 min.): https://goo.gl/XkKxHL


The presented work deals with the swing-up of the triple pendulum on a cart. The swing-up maneuver is accomplished within a two-degrees-of-freedom control scheme consisting of a nonlinear feedforward controller and an optimal feedback controller. Based on a precise mathematical model, the feedforward controller was obtained by solving a nonlinear two-point boundary value problem with free parameters. A time-variant Riccati Controller was developed in order to stabilize the system along the nominal trajectory and an Extended Kalman Filter was used to estimate the non-measurable states. The overall control strategy for the swing-up maneuver was successfully implemented and tested on an experimental test bench. Up to the authors’ knowledge, this is the first contribution so far providing numerical and experimental results of the swing-up maneuver for a triple pendulum on a cart.

A few weeks ago, I posted (goo.gl/mE052w) about one of the stranger legacies of the Cold War – a never-launched (for obvious reasons) American plan involving an Atomic Zeppelin fleet, which would patrol over the world's oceans 24/7, carrying Minuteman ICBM's on board.

Now, this plan was raised as part of a fairly transparent ploy by various groups at the Department of Defense to claim that they had "thought through all options" and could therefore justify the M-X Missile program.

So I have no idea what the excuse is behind this thing, a description of a plan for nuclear-powered Zeppelins to be fielded by the Soviet Union. I'm suspecting that this appeared in Tekhnika Molodezhi for much the same reason that bizarre designs show up in Popular Mechanics: that is, as an "imagine this neat future!" gimmick rather than serious engineering.

But I'm oddly pleased to discover that both sides of the Cold War had people that looked at nuclear reactions, looked at Zeppelins, and immediately thought these are two great tastes that taste great together.

This really strange bit of lore brought to you by @PulpLibrarian over on Twitter.

"People who appreciate the beauty of mathematics activate the same part of their brain when they look at aesthetically pleasing formula as others do when appreciating art or music, suggesting that there is a neurobiological basis to beauty.

Beautiful formula
There are many different sources of beauty - a beautiful face, a picturesque landscape, a great symphony are all examples of beauty derived from sensory experiences. But there are other, highly intellectual sources of beauty. Mathematicians often describe mathematical formulae in emotive terms and the experience of mathematical beauty has often been compared by them to the experience of beauty derived from the greatest art.

In a new paper published in the open-access journal Frontiers in Human Neuroscience, researchers used functional magnetic resonance imaging (fMRI) to image the brain activity of 15 mathematicians when they viewed mathematical formulae that they had previously rated as beautiful, neutral or ugly.

The results showed that the experience of mathematical beauty correlates with activity in the same part of the emotional brain – namely the medial orbito-frontal cortex – as the experience of beauty derived from art or music.

Activity in the brain is strongly related to how intense people declare their experience of beauty to be – even in this example where the source of beauty is extremely abstract.

Yesterday's ideas of the future tend to date rather quickly, because they usually miss the unexpected developments that come  next. I was struck how there's no television as they knew it in 1967, but there is private (3D?) recordings of performers. Also, in almost the whole of the house, there only seems to be one device with a QWERTY keyboard, and when the man of the house decides to send a message, he WRITES one using a stylus. Why wouldn't he just do a video recording?

Neutron stars are fascinating.

This cool infographic provides a visual approximation of their incredible density (hint: smash 500,000 Earths into a sphere ~20km across and you'll be close), but their story is actually even more interesting than that.

Neutron stars are born, so to speak, from the supernova death and subsequent gravitational collapse of a large star with 10-30 times the mass of our sun. That gravitational collapse squeezes the core of the star tighter and tighter - beyond the density found in a white dwarf star, to that found in atomic nuclei.

At its surface, the neutron star is composed of ordinary atomic nuclei (likely iron) crushed together into a solid lattice, with a sea of electrons flowing through the gaps between them. Deeper down, the nuclei hold ever-increased numbers of neutrons - so many that the usual nuclear forces would not be enough to hold the nuclei together. Only the absolutely insane gravitational force is able to hold the neutrons together in this configuration. (If you could, hypothetically, scoop up a teaspon of this stuff, it would not only weigh 900 times as much as the Great Pyramid of Giza, but also (more problematically) explode apart with such force that it would obliterate the unfortunate planet you attempted to weigh a chunk of neutron star on. Whoops!)

Of course, the rules of the universe do still apply to neutron stars. Stars rotate (our sun rotates once every ~24.5 days), and when the core of a massive star compresses and collapses into a neutron star it retains most of its angular momentum. You've seen a figure skater pull their arms in toward their body and thus spin faster? The same applies here: as the mass of the core pulls in tighter, it reduces the star's radius (and thus its moment of inertia) causing the neutron star to spin incredibly fast - often several hundred times per second.

Neutron stars are generally detected from their electromagnetic radiation, which is thought to be caused by particle acceleration near the neutron star's magnetic poles. Those poles aren't necessarily aligned with the neutron star's rotational axis, resulting in a directional beam of radio waves and other radiation. And, remember, these things are spinning fast, sweeping that beam across the universe like a rotating red or blue light atop an old police car. When seen from Earth, such beaconing neutron stars appear to rapidly pulse - which is why they get called pulsars.

This is seriously cool stuff! Be sure to dip into the linked Reddit thread to learn more about these incredible objects.

This is an old 2010 article. It may have been either discredited or updated by now. But the idea that young adults (ages 18-25) can be affected by this is intriguing, because it might support the suppression of derogatory terms and names    But does the same thing happen after that age range?

It's also the sort of report that gets grabbed and quoted by folk for their own agendas.. Quantum Mechanics (usually called Quantum Physics" by its appropriators)  used to be one of these, used to support all kinds of unlikely conclusions. In practice it's akin to quoting the 10% of the brain" myth - an appeal to authority  which relies on people's ignorance of the the source.

Should I buy Poser 11?

Should I buy Poser 11? Smith Micro have a sale on at the moment (ends 13th Nov), and I can upgrade from Poser 9 to Poser 11 for $US 49.99.

I bought Poser 9 some years back as part of a package with other SM products. I use Manga Studio (now Clip Studio Paint) a lot, but I never got around to using Poser at all. I was going to use it mainly for creating both avatars, poses and animations for Second Life / Open Simulator. What happened was that in-between when i bought it and now, I completed a Masters in Fine Art, and really didn't have the time to explore Poser at all. But now I do. I already have a version of DAZ as well, but haven't done anything with that for the same reasons.

So for the purposes mentioned above - avatars / poses / animation - is it worth my while upgrading from 9 to 11? What do I gain by doing that? I already use Qavimator and I have_ DAZ_, so is i9t worth it?

Comments please.

“During the last decade, when neutrino masses were constrained for the first time (via neutrino oscillations), it surprised many that they were found to be very low in mass, but to have definitively non-zero masses. Why is that? The general way of explaining this — the see-saw mechanism — typically involves additional, very heavy particles (like, maybe a billion or a trillion times more massive than the Standard Model particles) that are extensions to the Standard Model; without a new particle, their tiny, tiny masses (just a billionth of an electron’s mass) are completely unexplained. Whether see-saw-type particles exist or there’s some other explanation, these massive neutrinos are almost definitely, in some way, indicative of new physics beyond the Standard Model.”

When you think about the Standard Model of particle physics, you very likely think about all the matter, energy, particles, antiparticles, forces and interactions of the Universe. And you might legitimately worry that this is all there is. With the LHC confirming that there’s no low-scale supersymmetry or collider-accessible extra dimensions, and that all the decays and branching ratios align with the Standard Model’s predictions, that worry seems well-founded. Never fear; we know there’s more! The Standard Model may be wonderful for what it does predict, but we know with absolute certainty that it can’t be everything. From dark matter to massive neutrinos, from the strong CP problem to baryogenesis and more, there are five very strong pieces of independent evidence that show there’s more to the Universe than what we presently can explain.

Come see if you can identify all five independent lines of evidence for new particles and interactions beyond the Standard Model!

The Fake Cell Phone Towers

The creative attempt to disguise Cell Phone Towers of the mobile infrastructure as something natural (almost insulting).
Photographer Dillon Marsh has documented some of the most egregious examples.

Dillon Marsh, a South African photographer, has created a photo series of the incongruous pieces of infrastructure. They’re from various places around that country: Durbanville, Paarl, Stellenbosch, Eerste River. Amazingly, it seems as though the problem is even worse there: the giant trees are made even more surreal by their total misplacement.

Marsh says he became "intrigued by [their] peculiar nature" after a tower went up near where he grew up. Then he started seeing more of them, and he became hooked:

"In 2009, when I came across another one, I decided to track down and photograph as many of them as I could find around Cape Town. This proved to be way more than I expected and in the end I decided to limit the series to 12 photos so that I could concentrate on new projects."

A more sophisticated theoretical framework accounting for the observation that the universe is not exactly homogeneous and that its matter content may not behave as an ideal gas - two key assumptions of standard cosmology - may well be able to account for all observations without requiring dark energy. Indeed, vacuum energy is something of which we have absolutely no understanding in fundamental theory.

'Want a fun activity that benefits native bees and that the entire family can do right in your backyard? Build a bee hotel.

A bee hotel is a place you create for native bees — particularly mason bees and leafcutter bees — to make a nest. "The thing about a mason bee home is that it gets people to understand that there are a lot more bees out there than just honeybees," said Becky Griffin, community and school garden coordinator at the Center for Urban Agriculture and University of Georgia Extension for the Northwest District of Georgia.'

Computer weirdness today. I have two computers in the Studio and they seem to have opposite problems.

Computer weirdness today. I have two computers in the Studio and they seem to have opposite problems.

The first is the new version of the Studio PC. Win 7 installed on perfectly. Connects to the Internet and the Home Network. I installed Linux Mint KDE 17 on it as a dual boot, but it only boots straight to Win 7 (/dev/sdb2) unless I use the Supergrub 2 live disk to boot it to Mint. But then I find that Mint has no connection to either the Internet or the Home Network, and neither does the Mint KDE 17 live disk! This is odd, as I thought it had connected to both while in the RecRoom (on another LAN cable). Most peculiar, but it also means I can't install the Grub update for KDE either.

The other is the ex-University Laptop. I did a dual boot install of Mint KDE on that one as well, with Win Vista. The dual boot works perfect and both OSs boot fine. But Win Vista doesn't access either the Internet or the Home Network, whereas Mint accesses both. Not only that, it shows up as a computer on the Home Network and I can share locations on that as well!

I expect it's the same problem on each, in that on the Studio PC Mint doesn't have a driver for the network adapter, where on the Laptop (an older Dell model) it did, whereas when the IT department re-imaged the laptop that didn't include up-to-date drivers for the adapter! Luckilly I have all the original disks that came with the laptop, and the manuals, so I should be able to find the driver somewhere there and get that working. And for the Studio PC, which has a Realtek PCIe GBE Family Controller, I should be able to download the linux drivers from  the manufacturers site, and somehow install those (have not done too many manual installs under Linux).

But it's just bloody awkward on both. Of course I could just leave the Laptop as it is, and use the Win Boot to check suspicious disks and memory sticks, et cetera. Then if safe I could swap to Mint and copy the files to the network. Or not. This is the sort of task where I attempt to follow up in the most straight-forward manner, and find myself getting lost very quickly. D'Oh!

Maybe I could give that Google OS a ago? Thoughts on this?

An uncomfortable truth suggested by the Roman bot is that many of our flesh-and-blood relationships now exist primarily as exchanges of text, which are becoming increasingly easy to mimic. Kuyda believes there is something — she is not precisely sure what — in this sort of personality-based texting.

To me it inicates just how much of our "internet connections" are mostly in our heads. Of course this was someone she knew IN PERSON rather than only via the net. At best this is a way of coping with grief. At worst, it's a travesty that puts words in the mouths of the dead (which is something I hate and why I dislike bogus quotes).

Generating plasma inside a microwave

Plasma is one of the four fundamental states of matter (others are solid, liquid, and gas) and the most abundant form of matter in the Universe. It is comprised of ionized atoms with either a positive or negative charge and free electrons. 

As the match burns, electrons are torn from their atoms when chemical bonds break within molecules. Normally those electrons would immediately be re-captured to form the byproducts of combustion. However, the energy provided by the microwave radiation causes this cloud of intermediate ions and free electrons to persist in a semi-stable state. The intense light is a result of these high-energy particles losing energy before being re-energized by the microwave. When the microwave is turned off, the plasma will immediately dissipate since it no longer has the requisite energy to exist. 

WARNING: Doing this could damage your microwave! Also, if you're going to record a video of your microwave, please clean it beforehand.

Heliocentrism vs Geocentrism

The geocentric model is an outdated description of the solar system where the Earth is at the center of all the celestial bodies. The stars were thought to be fixed points on a celestial sphere that rotated around the Earth once a day while the planets followed complex orbits. This concept served as the predominant cosmological system in many civilizations for centuries until being replaced by the heliocentric model in the late 16th century. In contrast to geocentrism, heliocentrism claimed the Earth and other planets rotated around the Sun.

While the heliocentric model was proposed as early as 300 BC, it was not until the 16th century when a geometric mathematical model presented by Nicolaus Copernicus ushered in the Copernican Revolution. Over the course of the next century, observations by Johannes Kepler and Galileo Galilei helped solidify the heliocentric model as scientific fact. Further observations revealed that the Sun, although the center of the Solar System, was not the center of the galaxy or the Universe.

It all started in the early 1970s, when the psychologists Daniel Kahneman and Amos Tversky conducted an influential series of experiments showing that all of us, even highly intelligent people, are prone to irrationality. Across a wide range of scenarios, the experiments revealed, people tend to make decisions based on intuition rather than reason.

But really it's both a fallacy and over-simplification that a "high intelligence" leads to a high rationality. There's reason to believe hat there may be several types of intelligence (see https://en.wikipedia.org/wiki/Theory_of_multiple_intelligences) and being intelligent in one of these is no guarantee of being intelligent in another. Reason is a tool, and not the same as being rational. My mother, who has dementia is quite rational, but only within the parameters of her dementia. She will crate theories about her environment, based on her perceptions, but those perceptions are affected by her condition, and are not always reliable.

Also, I don't think that intuition is the opposite of rationality or reason. Reason relies on the pars of our brain that relate to language, but not everything we know or feel connects to that, and intuition, which comes from those bits, relates to us via an emotional chord. The trouble with rely on only on intuition is that it's easy to confuse one's hopes and fears (especially paranoia) with it. To use intuition properly, you have to be both open to your emotions, but at the same time not be totally driven by them.

Good news!
"It is, of course, unrealistic to think that we will ever live in a world where everyone is completely rational. But by developing tests to identify the most rational among us, and by offering training programs to decrease irrationality in the rest of us, scientific researchers can nudge society in that direction."

well, now I have the Studio PC setup in the Studio again, I have the same problem with that I had before - it's extremely difficult to use it for internet stuff. Running applications like Photoshop, no problem, everything's very clear. Browse Facebook and some other sites and the highlighting seems back to front, and the text very unclear.

I have an AOC e2343F 23" and you either have to use the buttons on the base to change the settings (urg - very frustrating to use), or run something called i-Menu. Only the program version only allows you to change half the settings. Very odd. I had endless trouble with this when I was doing the Masters. I suppose I should think about swapping the monitors around, though this one has a larger resolution of 1920x1080.

I was surprised to see that this free utility for Windows actually works on Win7!

I was surprised to see that this free utility for Windows actually works on Win7! What it does is allow you to disable the caps lock, disable the insert key, and make changing to CAPS ONLY via pressing Shift+Caps at the same time.

Knot mosaics

This picture by Samuel J. Lomonaco Jr and Louis H. Kauffman gives some examples of knot mosaics. A knot mosaic is the result of tiling a rectangular grid using the 11 types of symbols listed in the diagram, in such a way that (a) the connection points between adjacent tiles are compatible, and (b) there are no connection points on the outer boundary of the rectangle.

A natural combinatorial question is: how many ways are there to inscribe a knot mosaic in a rectangular grid of a given size? To make things slightly easier, we may assume that the grid is an n by n square, rather than an m by n rectangle. For a 1 by 1 grid, we have no choice other than to use the blank tile. For a 2 by 2 grid, we can either use four blank tiles, or we can arrange four tiles to draw a circle in the middle of the grid. For a 3 by 3 grid, there are a lot more possibilities: it turns out that there are 22 in all. As n increases, the number of knot mosaics grows very quickly. The first few values are 1, 2, 22, 2594, 4183954 and 101393411126.

To get an idea for how quickly this sequence might be growing, consider the much easier problem of filling a square grid with tiles that do not have to fit together compatibly at their edges. There are 11 types of tiles, and n^2 spaces in the grid, so the total number of ways to fill the grid is 11 to the power n^2. The great majority of these do not lead to knot mosaics, but the recent paper Quantum knot mosaics and the growth constant by Seungsang Oh (http://arxiv.org/abs/1609.00517) proves that there exists a constant δ, called the knot mosaic constant, with the property that the number of knot mosaics in an n by n grid, for large n, is approximately δ to the power n^2. Because there are 11 types of tiles, it follows immediately that δ must be less than 11. The paper gives a much better estimate, namely that δ lies between 4 and 4.303.

Although knot mosaics might seem like an isolated curiosity, they have applications to knot theory and quantum physics. If one imagines the left and middle knot mosaics in the diagram as physical loops made out of an elastic material, it is possible to see that it would be possible to deform one of these links into the other without breaking the material. Mathematically, there is an operation on knot mosaics that has the effect of interchanging these two knots. However, the third knot turns out not to be equivalent to the others, in a way that can be made mathematically precise.

In their 2008 paper Quantum Knots and Mosaics (https://arxiv.org/abs/0805.0339) Lomonaco and Kauffman use the knot mosaics as a basis for a Hilbert space called the quantum knot state space. The paper defines a group of symmetries generated by mosaic versions of the Reidemeister moves and mosaic versions of planar isotopies, and this group acts on the mosaics. The Hilbert space is meant to capture the quantum embodiment of a closed knotted physical piece of rope, and the group represents all the possible ways to move the rope around, without cutting it or letting it pass through itself. However, unlike classical knotted pieces of rope, quantum knots can model superpositions of several pieces of rope, as well as quantum entanglements.

The picture comes from the arXiv version of Lomonaco and Kauffman's paper.

The On-Line Encyclopedia of Integer Sequences has a longer list of values for the numbers of n by n knot mosaics. This one goes up to 11: http://oeis.org/A261400

Here's another post by me with more details on the Reidemeister moves: https://plus.google.com/101584889282878921052/posts/4e4STv3FLa4
