Not to be nit-picky, but force and gravity are the same thing (http://en.wikipedia.org/wiki/Equivalence_principle)
When we're talking about variations on the scale of a few atoms, everything matters including some normally imperceptible forces due to the relative positions of everything and small electrostatic forces as well.
On behalf of the men and women who serve in the military, I think your comment is ill advised.
Regardless of whether you, I or they agree with our government's actions, they risk everything to protect you the best way they know how. Don't blame the military for what you don't like. Become involved in politics to put decision makers in office that order the military to do what you believe is right.
I'm old enough to remember the shameful way that veteran's were treated returning from Viet Nam and I hope that horrible chapter in history is never repeated.
The fact that your comment is modded insightful to the max is pretty disturbing.
I got Google Glass for Christmas and what I've read doesn't really align with reality.
While I suppose you could roll the video recorder nonstop, the glasses get warm and wear the battery out pretty fast. Glassholes as walking surveillance cameras is not reality. There are lots of clandestine cameras out there already and that's not what Glass is about. You can take a picture by winking, but that's pretty obvious, and also potentially unnerving.
I need reading glasses so prescription lenses will be a big help.
Glass without the lenses makes you look like a cyborg sticking a camera in everybody's face all the time. Glass with the lenses clipped on makes them look like a lot more like normal glasses that most people don't immediately care about. Adding a neck strap and putting the glasses on (which by the way powers the device up) pretty much eliminates you being a big glasshole.
I wore it for a full day and was surprised at what I actually found useful. Its nice to glance up and see the time - they are more comfortable for me than a wristwatch. While I was exercising, having a timer right above my field of vision was really nice; this helped when cooking a meal too. I'm looking forward to having it show my heart rate with a Bluetooth Polar monitor strap. I found myself googling information I wouldn't have bothered to look up otherwise. I was pleasantly surprised that I liked the hands-freedom of it acting as a Bluetooth phone headset.
Google Glass is both a glimpse of the future and not ready for the mass market. Google calls early adopters willing to experiment and write applications for Glass explorers. Criticizing Glass at this point would be like telling the the Wright brothers that their plane was lacking in so many ways in the early days of flight.
I'm not sure Glass will have an immediate consumer killer app, but the business use cases are very much there. Taking inventory in a store or a warehouse where having both hands free, but looking at a barcode and speaking the quantity is interesting. A cashier or a warehouse worker having a scanner and speech input device with both hands free could be compelling. Anybody who is not sitting in front of a computer but needs to monitor process status or receive alerts is another obvious use case for many business applications; yes you can do that now with a phone, but you have to operate the device with your hands as opposed to glancing up.
I got the High Power Wall charger too but had Tesla's recommended electrician install it in our garage. They had to come out to perform an update to charge at the full 80 amps but other than that its been no trouble at all. I've only noticed that the cord leading to the card get's slightly warm but certainly not hot. I dial it back to 60A unless I'm in a hurry because I suspect its easier on the batteries.
Either way I wouldn't recommend a non-electrician to do this without a building permit. If there was a fire, the insurance companies would probably try to deny the claim.
Right on! What's wrong with safe and healthy gasoline with the added bonus of our money going to wonderful people busy protecting our environment and supporting our politicians?
From the reading I've done, it's met most of its objectives. Many of the goals and experiments don't need mobility anyway. It's not like it can't move either even with the existing and anticipated state of wear.
It does raise an interesting question though. Due to the cost of getting stuff there, should future missions include repair robots to reuse or recycle the stuff already on site?
On the + side of cloud computing as opposed to hosting your own server infrastructure:
Its nice to have a team on duty 24X7 when things go down.
There are economies in scale when you need lots of bandwidth, full redundancy as well as geographic distribution.
If you have HIPAA or PCI Level 1 requirements it nice to have a well equipped team to handle monitoring, log review, incident response, separation of duties and third party audit.
Is there personal health information (HIPPA/HITECH), or credit card information (PCI) at risk? If so get another job immediately and if personal circumstances permit, give notice immediately. This may be also advisable if you have information about specific minors.
If the above is not the case, the company's reputation is at stake and the millions that would be spent on PR firms to patch a PR mess should be forestalled. Tell the boss that a little CYA may not be a big deal. Take a look at Nessus, Metasploit and WireShark. Use the free trials if you have to. A pro will put in some extra hours to learn these tools. This should readily uncover the egregious risks.
Today anybody who doesn't make reasonable efforts to bake security into their code should be held accountable. Since you've outsourced the work, the vendor should stand behind their work. They are likely obliged to under their master services agreement - but don't wait too long.
Don't you have a Chief Security Officer or an information security policy? Discreetly tell those kind of guys your concerns and I bet you get action, especially if you have some reports from the scanning programs I mentioned.
You make a good point. One thing we are seeing here in Chicago is free charging at pharmacies, shopping malls and grocery stores. If they can attract a shopper who will be there for a half hour or more, a dollars worth of power is a winner for the merchant. Maybe that and super charging stations are how you be getting your vehicle's power.
We didn't even notice a jump in our electric bill after buying the Tesla. Our air conditioner uses way more power. Also, there is an easy to use setting that delays the charge until after midnight. Electric cars are not like gas cars in that you generally fill an empty tank. You top it off ever day or two.
Its definitely not going to battery pack heaters. That's a myth. I live in Chicago and its cold as hell right now. In the morning now that we have winter temperatures our Tesla tells us that its warming the pack when we start driving and the colder it is the longer it takes to warm up. Depending on how cold the car is, the system limits acceleration and regenerative braking. Even with the reduced acceleration it is still an incredibly fast car.
The simple explanation is that the computers and other electronic devices chosen were not selected for energy efficiency but for high performance. I'm happy with that trade-off.
We've had one since April and this issue is hardly noticeable. The last software update shuts some more stuff off by default and saves a little energy. Frankly I prefer it using a little bit for everything to be instant on. The 5 seconds or so the dashboard takes to turn on in the new power saving mode was a little disconcerting at first. The fact is for us its still almost 8 times cheaper than the gasoline car it replaced to drive per mile. Also where we live we have a green power option so our power bill money goes to renewable resources.
The benefits of this car are jaw dropping. The downsides are hard to find and the detractors have to resort to hysterical headlines. IMHO the primary valid argument against the Tesla is that its more expensive than most gasoline cars. I believe its important that people buy electric cars so all aspects of the technology can be improved and the cost brought down. I'll be surprised if in ten years nearly all new cars aren't fully electric. It's going to be like film and digital cameras.
You make two good points.
"That you can "get away" with something isn't a reason to do it." I made a poor choice of words. The experiment described in TFA is actually very cool (pun intended). What I'm trying to say is that the people who have a lot at stake in this field are afraid to rock the boat by expressing their misgivings about some of the underpinnings of quantum computing. I'm not trying to win a nobel prize here or yell fire in a theater, my aim is to gain a better understanding of reality and strengthen physics in general. I don't see how a defense of the status quo against these kinds of arguments can do harm and in fact they strengthen science.
"But we have gotten quantum mechanics to work well on single particles." I'll be sure to study what you have referred to. Previous review of experiments I've seen left me with the impression that the experimenters were failing to take into account the effects of the outside world on single particles and ignoring alternate explanations of the results. Its all to common to cloak to see these ideas in a thick armor of complexity and jargon but its worthwhile to review time permitting.
"if you agree that these statistics do describe accurately what results to get"
Yep, I agree completely and that's why I say that statistical formulas can be useful for large numbers of entities. But for a single particle - nope - not the right tool.
And herein lies the core the argument - Bohr vs. Einstein
My position is that Einstein was right, God does not play dice and the universe is fully deterministic. Unfortunately the mathematical model to describe a deterministic universe would need to take into consideration the state of every single charged and massive particle in the universe - obviously not possible - but that's our reality. Statistical math comes to the rescue and provides an acceptable and useful model that will match experimental evidence for bulk entities. This is much like a road map which is a very useful tool, but we must remember that the width of the lines representing roads are not to scale.
" it may be worth noting that this is a common response to things people don't like"
I love the idea of a quantum computer. I seriously hope the position I've taken is wrong, Quantum computers that take advantage of entanglement and superposition would be some seriously awesome magic whose ramifications are unimaginably profound. It would arguably be the important advancement humanity has ever produced to date. Unfortunately I don't think a breakthrough can be around any corner. Its a high stakes gamble for researchers to pursue, and it must be pursued. But we cannot depend on success any more than buying a lottery ticket to feed a family.
If theoretical advancements in physics turn out to be a trip down a blind alley based on false assumptions, its important for people to consider alternative ideas. Because my career isn't in theoretical physics, I can get away with making controversial statements that at least should be considered.
Quantum entanglement - really??? Can a cat be alive and dead at the same time? Huh???
Could all this be non-science and a misinterpretation of statistical math that doesn't really describe reality?
The underpinning of quantum computing is the idea that a qubit has the ability to be in more than one state simultaneously. This is simply illogical.
Don't shrug it off and say "things work counter-intuitively at the subatomic level"; that's a philosophical cop out and is not science.
The quantum is a profound realization that electrons can only be at discreet energy states based on the wave like nature of electrons whose energy state can only exist in even multiples of their wavelength. Why is the term being commandeered to imply that quantum can represent multiple states simultaneously.
The theory is that a single qubit can represent a one, a zero, or any quantum superposition of these two qubit states. Quantum superposition is a useful statistical tool and that is all. To go out on a limb and try to actually engineer useful machines on this concept - well good luck with that.
True quantum computing where single atomic energy states, spin and other subatomic energy states are used to represent information can keep Moore's law alive for decades. Hopefully not too much time and energy will be wasted on magic, smoke and mirrors and pseudo-science.
You would be better off if you only swiped through an iPad. All these iPad swipers are encrypted and tamper proof with decryption only possible at the card processor. The majority of the regular swipers you see at retailers do not use the end-to-end encryption.
"Did anyone feel any compassion for the people that Ender killed? No."
Reread the last few chapters. I certainly felt compassion for the enemy as well as remorse and so did Ender.
Missing this critical idea is the most critical aspect of the story and what made the book great.
Slashdot Mirror
LOL, read about her history. She was a genius.
Marie Curie not a great? Two Nobel prizes in different fields - even Einstein cannot claim that. Only one other has achieved that (Linus Pauling).
