Brian Greene, String Theory & the Gamow Memorial Lectures

Posted by in categories: business, education, particle physics, physics, policy, space

The University of Colorado Boulder holds its annual Gamow Memorial Lecture around this time of the year. This year, Feb 26, 2013, Brian Greene gave the lecture, on multiverses.

His talk was very good. He explained why there are 10500 possible variations to possible universes, and ours was just one of many possible universes, thus the term multiverse.

How interesting. This is an extension of the idea that the Earth or the Sun not being at the center of our Universe.

FUKUSHIMA.MAKES.JAPAN.DO.MORE.ROBOTS
Fukushima’s Second Anniversary…

Two years ago the international robot dorkosphere was stunned when, in the aftermath of the Tohoku Earthquake and Tsunami Disaster, there were no domestically produced robots in Japan ready to jump into the death-to-all-mammals radiation contamination situation at the down-melting Fukushima Daiichi nuclear power plant.

…and Japan is Hard at Work.
Suffice it to say, when Japan finds out its robots aren’t good enough — JAPAN RESPONDS! For more on how Japan has and is addressing the situation, have a jump on over to AkihabaraNews.com.

Oh, and here’s some awesome stuff sourced from the TheRobotReport.com:

Human Brain Mapping & Simulation Projects: America Wants Some, Too?

Posted by in categories: biological, biotech/medical, complex systems, ethics, existential risks, homo sapiens, neuroscience, philosophy, robotics/AI, singularity, supercomputing

YANKEE.BRAIN.MAP
The Brain Games Begin
Europe’s billion-Euro science-neuro Human Brain Project, mentioned here amongst machine morality last week, is basically already funded and well underway. Now the colonies over in the new world are getting hip, and they too have in the works a project to map/simulate/make their very own copy of the universe’s greatest known computational artifact: the gelatinous wad of convoluted electrical pudding in your skull.

The (speculated but not yet public) Brain Activity Map of America
About 300 different news sources are reporting that a Brain Activity Map project is outlined in the current administration’s to-be-presented budget, and will be detailed sometime in March. Hoards of journalists are calling it “Obama’s Brain Project,” which is stoopid, and probably only because some guy at the New Yorker did and they all decided that’s what they had to do, too. Or somesuch lameness. Or laziness? Deference? SEO?

For reasons both economic and nationalistic, America could definitely use an inspirational, large-scale scientific project right about now. Because seriously, aside from going full-Pavlov over the next iPhone, what do we really have to look forward to these days? Now, if some technotards or bible pounders monkeywrench the deal, the U.S. is going to continue that slide toward scientific… lesserness. So, hippies, religious nuts, and all you little sociopathic babies in politics: zip it. Perhaps, however, we should gently poke and prod the hard of thinking toward a marginally heightened Europhobia — that way they’ll support the project. And it’s worth it. Just, you know, for science.

Going Big. Not Huge, But Big. But Could be Massive.
Both the Euro and American flavors are no Manhattan Project-scale undertaking, in the sense of urgency and motivational factors, but more like the Human Genome Project. Still, with clear directives and similar funding levels (€1 billion Euros & $1–3 billion US bucks, respectively), they’re quite ambitious and potentially far more world changing than a big bomb. Like, seriously, man. Because brains build bombs. But hopefully an artificial brain would not. Spaceships would be nice, though.

Petition for Americium Emergency Stockpile

I continue to survey the available technology applicable to spaceflight and there is little change.

The remarkable near impact and NEO on the same day seems to fly in the face of the experts quoting a probability of such coincidence being low on the scale of millenium. A recent exchange on a blog has given me the idea that perhaps crude is better. A much faster approach to a nuclear propelled spaceship might be more appropriate.

Unknown to the public there is such a thing as unobtanium. It carries the country name of my birth; Americium.

A certain form of Americium is ideal for a type of nuclear solid fuel rocket. Called a Fission Fragment Rocket, it is straight out of a 1950’s movie with massive thrust at the limit of human G-tolerance. Such a rocket produces large amounts of irradiated material and cannot be fired inside, near, or at the Earth’s magnetic field. The Moon is the place to assemble, test, and launch any nuclear mission.

The Riddle of Cryodynamics (A Call for Cooperation with Lifeboat and Singularity University)

Posted by in category: physics

It is a riddle and almost a scandal: If you let a particle travel fast through a landscape of randomly moving round troughs – like a frictionless ball sent through a set of circling, softly rounded “teacups” inserted into the floor (to be seated in for a ride at a country fair) – you will find that it loses speed on average.

This is perplexing because if you invert time before throwing in the ball, the same thing is bound to happen again – since we did not specify the direction of time beforehand in our frictionless fairy’s universe. So the effect depends only on the “hypothesis of molecular chaos” being fulfilled – lack of initial correlations – in Boltzmann’s 19th century parlance. Boltzmann was the first to wonder about this amazing fact – although he looked only at the opposite case of upwards-inverted cups, that is, repulsive particles.

The simplest example does away with fully 2-dimensional interaction. All you need is a light horizontal particle travelling back and forth in a frictionless 1-dimensional closed transparent tube, plus a single attractive, much heavier particle moving slowly up and down in a frictionless transversal 1-dimensional closed transparent tube of its own – towards and away from the middle of the horizontal tube while exerting a Newtonian attractive force on the light fast particle across the common plane. Then the energy-poor fast particle still gets statistically deprived of energy by the energy-rich heavy slow particle in a sort of “energetic capitalism.”

If now the mass of the heavy particle is allowed to go to infinity while its speed and the force exerted by it remain unchanged, we arrive at a periodically forced single-degree-of-freedom Hamiltonian oscillator in the horizontal tube. What could be simpler? But you again get “antidissipation” – a statistical taking-away of kinetic energy from the light fast particle by the heavy slow one.

Keeping Humans Safe in Space: Meet Robot Torsos Justin, Robonaut, SAR-400, & AILA

Posted by in categories: fun, human trajectories, robotics/AI, space

JUSTIN.SPACE.ROBOT.GUY
A Point too Far to Astronaut

It’s cold out there beyond the blue. Full of radiation. Low on breathable air. Vacuous.
Machines and organic creatures, keeping them functioning and/or alive — it’s hard.
Space to-do lists are full of dangerous, fantastically boring, and super-precise stuff.

We technological mammals assess thusly:
Robots. Robots should be doing this.

Enter Team Space Torso
As covered by IEEE a few days ago, the DLR (das German Aerospace Center) released a new video detailing the ins & outs of their tele-operational haptic feedback-capable Justin space robot. It’s a smooth system, and eventually ground-based or orbiting operators will just strap on what look like two extra arms, maybe some VR goggles, and go to work. Justin’s target missions are the risky, tedious, and very precise tasks best undertaken by something human-shaped, but preferably remote-controlled. He’s not a new robot, but Justin’s skillset is growing (video is down at the bottom there).

Now, Meet the Rest of the Gang:SPACE.TORSO.LINEUPS
NASA’s Robonaut2 (full coverage), the first and only humanoid robot in space, has of late been focusing on the ferociously mundane tasks of button pushing and knob turning, but hey, WHO’S IN SPACE, HUH? Then you’ve got Russia’s elusive SAR-400, which probably exists, but seems to hide behind… an iron curtain? Rounding out the team is another German, AILA. The nobody-knows-why-it’s-feminized AILA is another DLR-funded project from a university robotics and A.I. lab with a 53-syllable name that takes too long to type but there’s a link down below.

ATLAS — Watchmen To The Hour That The Sky Falls In

Posted by in categories: asteroid/comet impacts, defense, engineering, events, space

With the recent meteor explosion over Russia coincident with the safe-passing of asteroid 2012 DA14, and an expectant spectacular approach by comet ISON due towards the end of 2013, one could suggest that the Year of the Snake is one where we should look to the skies and consider our long term safeguard against rocks from space.

Indeed, following the near ‘double whammy’ last week, where a 15 meter meteor caught us by surprise and caused extensive damage and injury in central Russia, while the larger anticipated 50 meter asteroid swept to within just 27,000 km of Earth, media reported an immediate response from astronomers with plans to create state-of-the-art detection systems to give warning of incoming asteroids and meteoroids. Concerns can be abated.
ATLAS, the Advanced Terrestrial-Impact Last Alert System is due to begin operations in 2015, and expects to give a one-week warning for a small asteroid – called “a city killer” – and three weeks for a larger “county killer” — providing time for evacuation of risk areas.

Deep Space Industries (a US Company), which is preparing to launch a series of small spacecraft later this decade aimed at surveying nearby asteroids for mining opportunities, could also be used to monitor smaller difficult-to-detect objects that threaten to strike Earth.

However — despite ISON doom-merchants — we are already in relatively safe hands. The SENTRY MONITORING SYSTEM maintains a Sentry Risk Table of possible future Earth impact events, typically tracking objects 50 meters or larger — none of which are currently expected to hit Earth. Other sources will tell you that comet ISON is not expected to pass any closer than 0.42 AU (63,000,000 km) from Earth — though it should still provide spectacular viewing in our night skies come December 2013. A recently trending threat, 140-metre wide asteroid AG5 was given just a 1-in-625 chance of hitting Earth in February 2040, though more recent measurements have reduced this risk to almost nil. The Torino Scale is currently used to rate the risk category of asteroid and comet impacts on a scale of 0 (no hazard) to 10 (globally-impacting certain collisions). At present, almost all known asteroids and comets are categorized as level 0 on this scale (AG5 was temporarily categorized at level 1 until recent measurements, and 2007 VK184, a 130 meter asteroid due for approach circa 2048–2057 is the only currently listed one categorized at level 1 or more).

Human Extinction Looms

Posted by in categories: asteroid/comet impacts, defense, ethics, events, existential risks, space, transparency

Humanities wake-up call has been ignored and we are probably doomed.

The Chelyabinsk event is a warning. Unfortunately, it seems to be a non-event in the great scheme of things and that means the human race is probably also a non-starter. For years I have been hoping for such an event- and saw it as the start of a new space age. Just as Sputnik indirectly resulted in a man on the Moon I predicted an event that would launch humankind into deep space.

Now I wait for ISON. Thirteen may be the year of the comet and if that does not impress upon us the vulnerability of Earth to impacts then only an impact will. If the impact throws enough particles into the atmosphere then no food will grow and World War C will begin. The C stands for cannibalism. If the impact hits the ring of fire it may generate volcanic effects that may have the same effect. If whatever hits Earth is big enough it will render all life above the size of microbes extinct. We have spent trillions of dollars on defense- yet we are defenceless.

Our instinctive optimism bias continues to delude us with the idea that we will survive no matter what happens. Beside the impact threat is the threat of an engineered pathogen. While naturally evolved epidemics always leave a percentage of survivors, a bug designed to be 100 percent lethal will leave none alive. And then there is the unknown- Earth changes, including volcanic activity, can also wreck our civilization. We go on as a species the same way we go on with our own lives- ignoring death for the most part. And that is our critical error.
