    Don't forget Venus's atmosphere is toxic acids including sulfuric and nitric acids. The windows in the lander sent to Venus were manufactured diamond. Still, it is inevitable that any lander there would quickly be eaten by the acids in the atmosphere. The fact that Ulysses survived 17 years in space with high radiation, at almost absolute zero and probably many micro-meteorite collisions is to be congratulated. How many 17 year old cars do you see that have never seen the inside of a repair shop? How many 17 year old electromechanical machines of any complex design have you ever known to not have needed repair of some kind? This is a machine with an onboard computer, communications, cameras, motors, engines, etc. So some parts are finally starting to fail, and they happen to be critical components.

  2. Re:Space doesn't curve ... or does it? on CERN Scientists Looking for the Force · · Score: 3, Interesting

    First IAAP (just not a PhD Physicist, so if that is your definition of a real Physicist, well then I guess I don't qualify).

    Secondly, it is not necessarily true to say Space doesn't curve. We are three-dimensional beings and thus cannot perceive anything in the fourth dimension. That is not to say that space-time is a physical dimension. It is a handy mathematical model which may or may not have an actual physical representation. The simple fact is, that if there is a fourth physical dimension to space, and there are many who believe there may be, and it doesn't violate any laws, so it is possible. Thus it is possible that Space is truly curved and we in like manner to Flatlanders cannot directly perceive higher dimensions. So the answer, as in many advanced Physics problems is that we really just don't know whether Space is curved or not, although you'll get all kinds of science speak that makes you think we do know.

    Lastly, it is common to refer to space as curved when dealing with many problems, and there are real reasons to consider the possiblility that space is truly curved, due to the properties of space around massively heavy objects, such as blackholes and our own Sun, which is massive enough to "bend" light. Or perhaps space-time is curved by the mass of the Sun.

  3. Re:Clear the DRAM? on Cold Reboot Attacks on Disk Encryption · · Score: 1

    Alternatively, a true geek hacker solution could be done, by making your own add-in board. The board, could consist of a battery or capacitors that charge up and when the computer is powered down in any manner, the circuitry on the board fills DRAM with a random sequence of bits. This solves the problem unless the computer is opened up and the board removed while the PC is still powered up. A solution to this would be to add a prom chip to the add-in, that gets loaded into memory at boot and does a ping back to the board. If the board gets pulled, then the resident program wipes RAM. While this would be a bad thing most all of the time, it would protect systems. Of course a much more sophisticated program could be written to selectively wipe sections of RAM. It's a safe assumption that if the RAM Eraser is removed then anything in memory is going to be lost anyway, so there's really no need for anything more sophisticated, but a more sophisticated would be nicer to anyone who has to administer the computer. Also, there may not be enough time for my brute force technique, so a targeted erase program might actually be worthwhile writing. This of course, won't stop someone from just yanking the memory out of a running system. So, really you can't protect the RAM as long at the computer can be opened by any means. Wiring explosives in the system (as some have stated) won't work either, because the case could be cut in such a way so as not to trip the explosive charges and the RAM removed.

  6. Ummmm ... no on Inventor to Launch Pop Bottle Rocket into Space · · Score: 1

    You're forgetting one small detail called terminal velocity.

    No way a bottle rocket is going to accelerate to 25,000 MPH on re-entry.

    First, it may enter Earth's atmosphere from the vacuum of space at 25,000 MPH if launched from space. But the drag of the atmosphere will quickly slow it down, releasing thermal energy in the process, and thus as you say melting it. Considering the shape and weight of a pop bottle, I don't see how it could possibly ever attain your fantastic speed, even meteorites don't surpass a few Mach on entry, which would give a not too dissimilar cross-section as a bottle rocket if it re-entered base first (assuming the flat outer base was removed. You see as the atmosphere became denser the drag force on the bottle-rocket will increase, thus counteracting accelerating force of gravity. The return velocity can be calculated by knowing the the mass of the object, the coefficient of drag, the cross-sectional area, and the density of air. If you shoot a bullet into the air at 19,999 MPH it will still fall back to Earth at the same speed as a bullet shot at 10,000 MPH, or even 5,000 MPH or 1000 MPH. A person shot out of a cannon at 5000 MPH will fall back to Earth at about 120 MPH, A person shot out of a cannon at 19,999 MPH will also fall back to Earth at about 120 MPH (the only object I know the terminal velocity of off the top of my head).

    None of this holds true for the Moon though, but it has a much lower escape velocity, so 500 MPH up = 500 MPH on impact.

    Lastly, I must say I'm impressed at anyone that can launch a pop bottle 1/4 mile up (367 meters ~ 1/4 mi). I wouldn't be surprised to see a height of a mile as a possible target. However, Mentos ain't gonna do it. Mythbusters proved that, not enough force, just a lot of bubbles. Now if you could find a way to burst the bubbles at the exit point, you might have something.

Just because you have a copy of something doesn't mean you own the original thing. Of course the case could be made that the recording industry has been stealing from the artists for years. That still doesn't alter the basic truth that distributing and aiding the distribution of copyrighted works without permission is wrong morally and legally. Two wrongs still don't make a right.

  9. Hybrid fallacy on Li-Ion Batteries Hit Final R&D Phase for Plug-in Cars · · Score: 1

    The thought that Hybrids are a good compromise is just flat out wrong.

    1) Hybrids have two engines, so they are heavier. Hence less distance on battery, less mpg, etc. from either one of the engines in the car.

    2) They have to have room for both batteries and a gas tank, thus reducing available space.

    3) It would be far better to get a trailer and load it up as a battery array for road trips and use a straight electric. While attaching a battery array for road trips isn't a cure all, because when you add the battery array trailer you've added weight. Adding weight reduces range. At some point you can't add any more battery to reach further. So with electrics there is a finite distance you can travel without a recharge regardless of how much battery power you add, which can easily be 300-600 miles. A well designed electric with the proper choice of battery can easily be built with a range of 100 to 300 miles with no additional battery packs (it's already been done in fact). Adding a trailer can easily triple this number, in most all cases. So, we're now talking a range of 300-900 miles on a single charge, but now you have to recharge the system. However, if you're creative you can find solutions to this. For instance. You build/buy a quick charge system. Travel as far as you can, go to a campground with electric hook ups. Pay for a night, plug in and charge your batteries, then either camp out or hit the road again or find a hotel. This will cost you from $8 to $30 per charge which should take you about 300-900 miles if you have a good enough battery pack. Where are you going to get 1 gallon (assuming a generous 30mpg) of gas for $0.27 and soon $3?

    4) Other solutions are to find someplace were you can plug into their electric for a charge, or someone that has a power generator you can hook up to or you can carry along your own power generator. Of course, by going the power generator route you're actually defeating the purpose of electrics three fold. The kind of generators we're talking about may dump more pollution than the original gas engine, you may not save anything, and you could get the same thing or better by going hybrid. No, to benefit from electric vehicles you want to plug in and charge, not use a gas engine to charge it.

    'Trademarks are infringed when there is a "likelihood of confusion" as to the source, affiliation, or sponsorship of the good or service.'

    If the club puts a prominent disclaimer on the calendar and makes it known in selling the calendars that they are not: the source, affiliated with, or sponsored by Ford(t) then they can sell them.

    As long as there is no "liklihood of confusion" as to the use of the trademarked item, Ford has no legal leg. Obviously, there's more to the law than that, but for this particular case that is the defining characteristic, and the hurdle that Ford and the Club need to overcome.

But, they could easily comply with the law and publish this without Ford's approval. All they need are the prominent disclaimers.

    Now, if they were selling t-shirts of the photos, I see no way they could not violate Ford's trademark. Without printing a BIG READABLE DISCLAIMER on the front or back of the tshirt. Even then it may not be enough.

    You're both wrong. And both right. Because you are both approaching the Constitution from the wrong perspective. The Constitution was drawn up to create a form of government that was strong enough to protect the people of the country and ensure domestic tranquility. In that perspective, the 14th amendment was added at the demand of one faction that wanted less power for the Federal government and the other which felt it was unnecessary to state the "obvious". They all agreed that a right to privacy was a paramount and inalienable right, and didn't feel it was necessary to explicitly state it. It was obvious. The obvious often goes overlooked. Just look at all the writings the founding fathers did anonymously. The Constitution wasn't meant to list the rights given to the people. It was meant to delineate the rights given to the Federal government and to the states. The remaining rights were to remain with the people. The problem they were trying to fix was how to give enough power to a government, which they all agreed needed to be watched to prevent abuses, so that the country wasn't crippled. Look back to your history books and read about how the Articles of Confederation worked and you'll see the reason for the Constitution. The right to privacy is an inalienable right, and is protected by the virtue that the power over our privacy isn't enumerated in the states' or federal government's rights. The exclusion of a right of the people in the Constitution is proof of it's remaining in the power of the people and not the government. The government is there for the people NOT the other way around. We are the masters, they are the servants. At least that was the plan. If the founding fathers saw the current state of the government, they'd be shocked and dismayed.
