Planetary data merge shows three Earth-like planets in close star system

... where gravity is less of a problem

Well, you have to consider that gravity doesn't just get cancelled out just because you're under water. Don't forget that you need to add up the total weight of the atmosphere *and* the liquid water above you. Some forms of life on Earth can tolerate extremes of pressure, but who knows if life could actually have started under such conditions.

Also, to be totally pedantic, just saying the planet is 10 times more massive isn't the whole picture. We also need to know what the planet's radius is. If it's large enough, the surface might have a tolerable gravitational force.

Re: Cold reading - And that's not just there website!

He (as a self confessed fake) beat the two "genuine" psychics.

Reminds me of the story from quite a few years ago that pitted Microsoft's technical helpline against some "psychic" hotline for fixing some Windows-related problems. The result was that they were both (surprisingly) relatively on a par with each other in their ability to fix the problems.

The point? I guess that anecdotal evidence is fun, but of little use otherwise.

Spaniards deploy self-propelled ROBOT BALLS

Frumious Bandersnatch
Bronze badge

Believe it or not

I already invented one of these years ago, though I never built a prototype. It's a pretty obvious design, though, and I'm sure it's been "invented" many times before.

To be honest, laziness played a large part in my not building the thing, although lack of experience in electronics was also a large factor. I'd wanted to incorporate two features that, after a bit of thinking, it was clear that I'd have to learn a non-trivial amount of electronic circuit design (and source the necessary components) to implement, so I never went any further than the imagining stage.

First, I wanted to use a standard radio controller, but I wanted the ball to have a network of receivers (at least 4 arranged in a tetrahedron, but an inscribed cube, other platonic solids or buckyballs would work too). My thinking was that as each of the (directional) antennae would be at a different orientation to the incoming radio signal, each of them would be receiving the signal at a different strength, so it should be possible to triangulate, roughly, where the RC signal was coming from. The point of this was so that if I pushed the RC stick towards the ball, it would travel away from me, and vice-versa. All motion would basically be relative to a line between the centres of the controller and the ball. That seemed to make most sense in the absence of some kind of external positioning system (like GPS, but finer-grained). It would mean you'd have to know roughly where the ball is in relation to your position if you want to steer it meaningfully, though.

The other tricky bit would have been coordinating the movement of the weights within the ball. It's (fairly) trivial to shift the weights(*) in the right sequence if you want the thing to move in a distinct set of "steps" (with it settling down to a new centre of gravity before applying the next movement), but if you want it to act more like a ball and move smoothly you need to factor in all the moments of inertia in three dimensions as well as the characteristics of the motors that move your weights in and out relative to the centre of the ball (how fast and how accurately they can move, where they are at any given moment, and even the lag between sending the movement command and being able to act on it). If you want variable speed control you need to be able to measure the current moments of inertia (using accelerometers that weren't that cheap or readily available at the time) and adjust how far you shift the weights when you're already going fast (like an ice skater can move their arms in and out to adjust speed when spinning). Mathematically, it's fairly complicated, but doable. Unfortunately, as I said, I lacked the skill in electronics to be able to translate the maths into a proper control circuit. The various feedbacks among inertial sensors, current and projected centre of gravity and the sensor array used to triangulate where the user is makes it all very complicated, particularly if the thing is moving at high speed. Depending on the size of the ball, you might have gone through a significant fraction of complete revolution by the time the circuit has figured out what it should do next, by which time that calculation is completely wrong for the current state. Quality, high-speed sensors is a big part in overcoming that problem, but at the time I didn't have access to them. Nowadays, I guess a mobile phone has most of the sensors needed for this kind of thing though it still needs something better than GPS for telemetry.

So, anyway, I've got to tip my hat to these guys. I'm not sure how they've implemented their telemetry or whether they've cracked the problem of controlling the ball at high speeds, but it's really nice to see that someone has had a proper go at implementing this kind of thing.

*a note on weights: another alternative form of locomotion would be to have various pistons spread around the surface of the sphere. By pushing them out and retracting them in the right order (and with the right amount of force) it should be quite easy to get the thing to move quite quickly. It does sound like a fairly industrial-level implementation, though, since you'd need more pistons than you would internal weights. There's also the problem of legs breaking off or getting stuck on/in things that doesn't happen if the ball is self-contained and only contains weights and motors. On the plus side, if you have pressure (weight) sensors on the ends of the legs, that's a pretty useful sensor to have for detecting not only which side is up, but also for collision detection.

The other form of locomotion that I considered, and I'm quite proud of, is to use two-way memory metal to construct the shell of the bot. The idea is that in one state each of the wires forms a strut of a platonic solid (eg, a dodecahedron), while in the other state the overall shape of the ball is deformed at the bottom and it tips over onto the next face. By alternatively lengthening and shortening struts in the right order, it should be possible to get it to roll in whatever direction we want. The beauty of this sort of bot (provided it could actually be built, and I haven't overlooked some crucial problem) is that the shell (and a few sensors, power sources and other electronics distributed evenly around the shell) essentially is the robot. Taken to the extreme, it should also potentially be possible to use the memory metal itself as the communications network medium so there'd be no unsightly wires or internal circuits even visible. If someone wanted to try this, they could build it as a set of nodes (vertices) containing the processing parts and then the user could build it simply by training the metal struts and building up the dodecahedron out of nodes and memory metal struts. That's one variation of this idea that I would really love to see someone implement!

Australian unis to test quantum-comms-over-fibre

Frumious Bandersnatch

re: Pishtosh

Wow... chill. Nobody's saying that entanglement allows instantaneous information transfer. The way this works is (roughly) that we send some photons using a recorded polarisation, the receiver sets up some polarising filters at random and then both parties communicate the results using standard (non-FTL) communication channels. The quantum magic happens because an eavesdropper can't know both the initial polarisation and the polarisation setting at the detector and any attempt to "copy" the photon in flight has at least a 50/50 chance of getting the polarisation wrong (assuming only two polarisation settings), thus alerting Alice and Bob to Eve's presence.

The whole system (from emitter to detector) is the quantum entanglement "experiment", so it's easy to see how an eavesdropper will prematurely collapse the probability waveform, ruining the values that Bob sees. But again, even though in normal operation, without an eavesdropper, the collapse is instantaneous with the measurement at the detector end, Alice and Bob still need to communicate their results before they actually know what that measurement means, so there's no FTL information transfer... so it's actually not Hokum.

Re: Any rope is the problem

That massive amount of current needed to shift an elevator car ends up producing immense amounts of heat

Well if there's that much hot air, why not tether a hot air balloon to the lift and use that to lift the cargo? You'd have to have the balloon "outside the box" (ie the building) which would definitely lead to challenges on windy days, but at least you might be able to use other waste heat from the building to keep it topped up. Sounds much nicer if you take the gondola to the 50th floor instead of a regular old "lift".

Re: Phew! I'm safe...

It's called steganography. Nothing to see here, move along now.

I haven't read the paper, but I don't think it's stego. According to the article, such inputs are used to trigger an existing infection rather than being used as a carrier for code or new information beyond the "trigger me now" signal. In this case, it's probably just another example of the use of "oblivious agents": an "agent" continuously monitors whatever sensor data it has available, produces a hash of some kind and if the hash matches a trigger condition, it activates. The "oblivious" part is that the agent doesn't "know" in advance (and examining the code won't reveal) what specific combination of inputs are needed for it to activate which function.

Re: No Brainer

To prove it's fusion you need to see what is in the box.

Not necessarily. If you seal the apparatus up and you have a really accurate scales (or a long enough time scale) to measure the mass of the thing, you should see a gradual reduction in mass. That would probably be enough to prove there's fusion going on. Or fission, but we have to take it at their word that there aren't any fissile materials in the box providing the extra energy output.

Charity chief: Get with it, gov - kids shouldn't have to write by hand

waapuro-baka

There's a phrase in Japanese (see title) that literally means "word-processor idiot". It refers to a problem that people are becoming less and less proficient at actually writing Kanji. The way this works on computer, people type in the words phonetically and then it gives them a choice of possible kanji. So while you still need to be able to recognise what the correct kanji is/are, it's actually deleterious to your ability to write those kanji from memory.

Although it's not as extreme a problem in English, I think this push to downgrade the importance of (hand-)written language in favour of typing things on a computer does have similar consequences. It's not exactly that handwriting itself is that big a deal, but I think that things like auto-completion and automatic spell-checking tend to make people lazy when it comes to learning how to spell things correctly and how to distinguish between homonyms like "their" and "they're". A spell-checker alone can't help you learn these things, and most grammar checkers aren't really up to snuff.

Den dares de problum wiv ppl using "is a computa" as an excuse not to even bovver wid writing "propurly"...

Maybe this guy's argument is more nuanced than I'm giving him credit for, but overall I'd have to say I'm against it. I'm all for increasing tech literacy, but if the price is to sacrifice literacy in general, it's not worth it.

Reg hack to starve on £1 a day for science

Frumious Bandersnatch

Re: I've got a top tip for all you pound a day guys who are smokers too...

Fags do suppress the appetite so it could be an aide to staving off the hunger

You'd be better off getting some garlic and rubbing a bit in your mouth. Apparently it's good at staving off the hunger.

Some other thoughts...

Various people have mentioned potatoes and rice, which is a great idea. You do need to make sure you're getting some protein, though, Dried beans, lentils and split peas are the best value, along with TVP (textured vegetable protein). Oils and fats will probably be your most expensive outlay.

Someone else mentioned foraging, but it's not practical if you're either living in the city or don't know what you're looking for out in the country. It also tends to be seasonal, but if you know what you're looking for you can get plenty of fruit and maybe mushrooms (requires knowledge and caution!) and definitely some plants like wild garlic and even dandelion or nettle that are easily identified and easy to find.

In the city, foraging is pretty hard. You could follow a squirrel back to its lair and steal his nuts, I suppose. Much easier is to find a supermarket where they're offering free samples of stuff. You could steal a copy of "Steal this Book" and get some ideas for other ways to get free stuff, or invite some friends around for some "stone soup" (you provide the stone).

Surviving on £1 a day sounds very hard, unless you "cheat" by relying on getting free stuff (like sugar and ketchup packs and butter pats from restaurants). As an awareness-raising exercise, though, I'd have to applaud it. Good luck with it!

Re: There is a helluva lot of difference

As soon as they start decelerating at the other end, they'll get a column of exhaust catching up, and smashing into them!

No. First, you have to understand inertial frames of reference. If I'm on the roof of train and I fire a gun in the forward direction, it will have the same apparent velocity (to me, and ignoring air resistance) as a bullet fired in the "backwards" direction. Despite being in motion, the relative velocities still work out the same as if we decide that (or it's actually the case that) the train is fixed in space. This is our "inertial frame of reference". Second, you need to take into account Newton's third law: "for every action there is an equal and opposite reaction", which is the principle behind any "reaction drive", of which this is an example. Again, consider the plasma exhaust coming out of our "gun". It has a mass that is a tiny fraction of the mass of the ship, but will have a large acceleration. Since F = ma (force = mass x acceleration) and due to Newton's third law, our ship will have a balancing (reaction) force propelling it in the opposite direction to the plasma. Since the ship's mass is so many times larger than the projectile, the resulting deceleration will be much less than that experienced by the projectile.

So in summary, (1) the projectile will always accelerate away from the ship, regardless of which direction we're going, and (2) catching up with the exhaust assumes you're going forward-backward-forward for some reason, rather than forward-backward, and even then, the chance of hitting the exhaust over such vast distances is crazily small. Also, (3) detonating the pellet and turning it into plasma means that after a short time there won't be anything except a diffuse gas for anything (including other ships in the vicinity) to collide with anyway.

Re: Form factor is nice...

Speaking of form factor, the first thing I noticed about this is that the power switch is on the top. That's either a design flaw, or perhaps a tacit admission that the heat output of these is such that stacking multiple units would tend to cause overheating. IF these things were cheap enough to use in a small cluster (and if it weren't crippled by only having USB 2) then I'd have thought being stackable would be a virtual necessity. I note that neither the Mac Mini nor the Chrome boxes have power switches on the top. I don't know if they have heat dissipation problems if stacked, but at least the power button placement doesn't stop you from trying it out.

Re: @Rampant Spaniel: Rights

While logically, a refusal to answer a question would imply guilt ...

No, it doesn't: not logically or legally. Previous posters have already covered what valid inferences (note: "to infer" rather than "imply") can be drawn from refusal to comment in criminal vs civil suits, so I've nothing to add. In terms of logic, though, it's obvious that no firm inference can or should be made from such a refusal to comment. Various logical possibilities exist, ranging from hiding one's guilt, protecting another guilty party or avoiding incriminating oneself for a different crime than the one being examined, the belief that the question need not be answered (for whatever reason), avoiding revealing something that is embarrassing (though not illegal, such as having an affair, being the subject of blackmail or whatever), simply not understanding the question or being incompetent, or believing that the question is unfair and best not answered ("so have you stopped beating up your wife?"). Logically speaking, a refusal to speak doesn't lend any weight to any of these (or other) possibilities being correct.

Apart from that, most of what you said was fair enough. It's just a pet peeve of mine when people talk about logic in a clearly illogical way. That, and mixing up "imply" and "infer"...
