Look up tether in a dictionary. Have you seen a suspension bridge before? Those skinny cables sure can hold a lot of weight. And if we can build spacecraft that can survive 3g we should be able build a space module that can survive 1g spinning without falling apart.
1) Moving the spinning thing is not a huge problem 2) One solution - no windows. Or use cameras. Nuclear submariners do fine without windows. I bet they are better suited to space than pilots (so most of that NASA research into humans living in long term confined environments was probably a waste too - the nuclear submariners have been doing it for years).
And at least research into building space stations/ships with artificial gravity is going to be more useful in the long run. You're not going to have humans long term in space sustainably - reproducing, living etc without artificial gravity.
In contrast research into space surgery in zero g is a waste of time and resources- this and most zero g research is basically like researching into dealing with bad stuff because you keep doing things wrong in the first place.
It's just stupid. They are wasting time and money doing research on crap like this when they should just spend it on building space stations with artificial gravity. You could do it with tethers and counterweights if you can't afford a huge space module.
So much research on the "problems of doing things wrong". You cannot have a sustainable human population in space without artificial gravity, so such "zero gravity" research is niche and near dead end for long term space travel.
Once you have artificial gravity and decent radiation shielding you can go to the asteroid belt which is a better choice than Mars since asteroids aren't huge gravity wells. It's not like Mars is a hospitable environment, so any talk of Mars is stupid at this point of time - it's like talking of jumping before you can even stand.
Yeah that's the problem with these laser weapons. I can see way more practical uses for guns than for these lasers. The harm to benefit ratio is way too low for these lasers.
Even for fun - you use your hand gun in a shooting range, it goes bang, it makes holes and it's unlikely the "reflections" will hurt anyone standing at the safe areas. Whereas using those powerful handheld lasers aren't going to be as fun, and the reflections can still blind people far away.
1) Isn't there a way to detect coherent/laser light? 2) Given the beam is 1 meter across and bright, you could tint the window when stuff suddenly goes bright - and that's good enough - whether it's a laser or powerful searchlight you're going to get dazzled anyway so if I were a pilot I'd rather the window be blinded than my eyes be blinded. I can still fly by instruments. Whereas my retinas might not heal enough = I lose my job or worse be permanently blinded.
Of course the perp could use more than one laser with different colours. In which case the perp when caught should be blinded with lasers and tattooed all over with "I am a sociopath".
I don't think these lasers will cause many planes to crash. But the pilots might suffer permanent eye damage.
And who pays for the pilots with permanent eye damage? Not like they can continue flying planes. In many countries the taxpayers and/or insurance policy holders would end up paying.
I don't know about you, but I value my eyesight highly. So the fewer assholes and kids going around with powerful lasers the better.
To me the benefit vs harm ratio is even better for personal handguns than for these lasers. What fucking great benefit to you and society is a powerful handheld green laser? So that you can point at stars? Use a long stick.Therefore I'd be very happy if such laser weapons are banned or at least regulated similar to fully automatic firearms. And people illegally using and smuggling them thrown into jail.
What's the security like? WiFi security has been abysmal for a long time. Unlike stuff like https, with WiFi you can't have encrypted but somewhat anonymous connections.
Stuff like WPA2 PSK is crackable, going to the "Enterprise" version of WPA2 requires RADIUS, usernames and passwords[1].
[1] In theory you could have a standard "anonymous" username and password for public "secure" WiFi networks but I don't see as standard for it.
I believe many vegans feel as long as it's consensual it's OK.
But if that's so then consumption of some dairy products could be fine in certain theoretical scenarios - apparently many highly productive breeds of cows nowadays need to be milked or it is painful for them. However I think you'd need to find very rich vegans willing to pay for milk from farms which treat cows really well.
I've said it before but I'll say it again: Steve Jobs was an asshole. But one with taste. Many people can emulate the assholeness (and do) but they have no sense of taste.
You can scream at the chefs and cooks in the kitchen as much as you like but if you have no sense of taste your restaurant isn't going to do well. But if you have a sense of taste, when you scream at them because something isn't great deep down everybody knows you are right and so even though the screaming isn't pleasant (or maybe even necessary) a fair number will accept it. And if you have an exquisite sense of taste, when you go "This is Insanely Great", they know you are right too, and it feels like a real achievement and affirmation.
I personally believe there is no need to be an asshole to get people to do great work. But you really do need to know what is good and what is crap.
It's more like research on how to survive long term on a boat without a roof. Dealing with sunburn, other exposure to the elements etc.
Just do research on roofs for boats, build better boats with roofs and the problem goes a way.
So as I said, build a spacecraft or space station with artificial gravity and the weightlessness problem goes away.
We do not have easy access to infinite resources. But there's plenty of stupid stuff to do research on. Just because NASA et all are doing it doesn't make it less a waste of time and resources.
Seems to me a large number of those experiments are to deal with the _problem_ of weightlessness. Thus most of those experiments are a waste of money AND time. The solution to that problem is to have artificial gravity- just build a space station that rotates (whether using tethers or not). If you are ever going to have humans living and reproducing sustainably in space that's what NASA etc should be doing work on. Not wasting time and resources to find out how poorly a human does in weightless conditions.
So unless someone can point out some noteworthy ones amongst the tons of crap to me I'll have to conclude that the most worthwhile and notable experiments the ISS has been involved in are the space tourism ones.
Yeah too bad full-face helmets are so heavy and uncomfortable.
FWIW I think horse riding is even more dangerous than normal cycling (e.g. not the sort where you cycle off a cliff etc), but those idiots insist on wearing helmets that belong in the 1920s or something.
They should be wearing much better helmets - you're higher up on a horse, horses can run fairly fast and they sometimes stop very fast unexpectedly.
It may be that a single neuron is actually not that stupid and it's because you need redundancy and the ability to control a large creature/"machine" that you have to have many of them and a multicellular body.
Does it really degrade performance? I've had motherboards with intel graphics, and I just plug an ATI/NVidia video card into them, install the drivers and it seems to work. Then if the video card fails (which does happen) I have the intel graphics to fall back on - so I can still use the PC for normal desktop stuff even if I can't play games that require higher graphics performance.
In theory to reuse the heat in the water you just have to make sure enough air passes the water (or something heated by the water) somehow - then the cooling of the air due to expansion will be reduced, and so the pressure will be higher than it would be otherwise.
I think LightSail uses the spray method to do that.
But it might not be necessary - you could have heat sinks in the storage chamber and water in the heat sinks to absorb the heat. This would be more expensive in terms of parts and material, but there would be no moving parts and no water in the air. But it might be harder to achieve a good enough heat transfer with the heatsink and fins method, compared to a spray of warmish water.
I'm not in the USA but can't you find stuff like: 1) potatoes/rolled oats/rice 2) eggs 3) sardines 4) green leafy vegetables or stuff like broccoli 5) fresh limes (do not add sugar- yes it's sour but you can get used to it - it's medicine;) )
In case of nutritional deficiencies not covered by the above food items, buy a bottle of multivitamins and have one tablet every 3 days (this is just in case you miss some nutrients, taking too much iron, E, etc is bad for health, so every 3 days should be OK).

You missed the "color filter" part.

I think it's a source of vitamin B12 too ;).
Apparently it also has mood enhancers.

Whether NASA likes them or not.
Then it just means you'll live long enough to get glaucoma or cancer instead of dropping dead earlier.
Seems to me you:
a) need to be a lot more careful
b) need to wear a helmet practically everywhere even indoors.
Yeah too bad full-face helmets are so heavy and uncomfortable.
FWIW I think horse riding is even more dangerous than normal cycling (e.g. not the sort where you cycle off a cliff etc), but those idiots insist on wearing helmets that belong in the 1920s or something.
They should be wearing much better helmets - you're higher up on a horse, horses can run fairly fast and they sometimes stop very fast unexpectedly.
To me it seems that they should figure out how the single celled stuff (like amoebae and neutrophils) think before they go on to more complex stuff.
From what I see they seem smarter than most people (including many scientists) assume:

Have our AIs reached the level of intelligence of an Euglypha amoeba, which builds a pretty decent shell for itself: http://starcentral.mbl.edu/microscope/portal.php?pagetitle=assetfactsheet&imageid=26590
It's quite an elaborate shell - with holes in the front and back. The number of "teeth" in the shell apparently is not determined strictly genetically either see 3) in:
http://what-when-how.com/molecular-biology/maternal-genetic-effects-molecular-biology/
Note that it builds a new similar shell when reproducing.
It may be that a single neuron is actually not that stupid and it's because you need redundancy and the ability to control a large creature/"machine" that you have to have many of them and a multicellular body.
I believe when the OP said "back in the Athlon X2 days" he meant back when the Athlon X2 was "The CPU" (and Intel had the P4 ).
Just because you can buy a brand new Bach CD today doesn't mean it's still "back in the Bach days".
More like at least 5 years ago: http://en.wikipedia.org/wiki/Athlon_64_X2

Is there really anyone out there who doesn't read "f**cking" as "fucking"?
I read f*cking as fucking but f**cking is a bit more
ambiguous.
