It's hard to write about the United States' National Security Agency without sounding like Gene Hackman in the film Enemy of the State. In fact, the more you read about the agency and its practices, the more you wonder whether the hyperbolic, Faraday-cage-living paranoid was being a bit blase. Thanks to leaks from exiled, former NSA contractor, Edward Snowden, we've found out that the spy agency does some really neat things! These include, without a warrant, recording every phone call that routes through the US, taking private data from basically every major web company and paying US telecommunications providers to have direct access to their networks.
The NSA has also circumvented or intentionally weakened encryption standards, which pretty much everyone relies on to protect sensitive data. The people working for the agency have also been caught using their godlike powers to stalk people they're attracted to, a practice so common it has a nickname - loveint.
Public Address blogger Keith Ng has described it as "the gift that keeps on making me barf". He must have been doing plenty of that lately: He was the one who joined the dots between the agency and our own Government Communications Security Bureau, realising that GCSB assistance is effectively NSA assistance, and the agency can use its vast powers on us too.
I mention him, by the way, to encourage you to check out his blog - he's posting a series of articles on how to encrypt your stuff that you really should read. For a while, I thought this was where we would all be heading now - a kind of worldwide Howard Beale moment, (from the film Network) where we would open our windows and yell about how we were "mad as hell" and were "not going to take it anymore", then start creating our own security systems. I don't know about you, but the NSA saga has already begun to be relegated to that category of stuff I'd rather not think about, like climate change, famine and the continuing existence of acerbic music reviewer Simon Sweetman. While I've just recommended Ng's encryption tutorial, I've had to force myself to re-read those posts and actually utilise the information.
To wit, another tech story has provided the perfect example of the world's ambivalence to worries about others having access to our data.
In the midst of the NSA's slow motion trainwreck, a more familiar tech story has returned: The release of Apple's new iPhone.
Called Touch ID, the 170-micron-thin scanner sitting under a sapphire crystal on the device's home button can capture 550 pixels per inch of a person's thumbprint.
Videos of the feature in action reveal it takes a few minutes to train the sensor to recognise a fingerprint (it can store five). Of course, it's not perfect: An article I read the other day said Apple testers had "found the device sometimes doesn't work with moisture-laden fingers covered in sweat, lotion or other liquids". It's also not new: Android phones and laptops have had the feature for a while now, though in a slightly clunkier manner. While Touch ID could remain a feature for Apple's high-end iPhone; if it does become a common feature for all of the company's devices, within a few years most users will have access to the technology. I'm interested and slightly concerned at this prospect of moving away from passwords and into biometric details. There is a powerful irony in us giving away more of our personal data, in order to keep our personal data secure. More practically, you can keep your passwords secret and change them if they are compromised. I'm not saying that Touch ID is inherently unsafe, or a potential security risk, or something you should avoid.
By all accounts, Apple has gone about implementing such a scanner in the safest possible way. The scanner scans at a deeper level than you'd be able to obtain by lifting a print from a surface (like the phone itself). Also reassuring in this age of NSA spookery is that the phone does not store an image of the fingerprint, just "fingerprint data", which is then encrypted and stored in the iPhone's processor.
Still, hackers have fooled biometric scanners before and until the device is actually released, it's hard to know how secure it will be. It signals a move into using more of our personal data - and more of our nature - than ever before.
This may be a win for us in the end, but it may just be yet another win - if more were needed - for organisations like the NSA.
Collision: Impossible In a critical scene in John Woo's motorcycle-heavy second installment of the Mission Impossible series, Tom Cruise and evil Dougray Scott have a head-on showdown on their respective high-powered bikes, which ends in a midair collision after each is somehow able to leap off his bike. In "Willy Wonka and the Chocolate Factory," when Charlie and Grandpa Joe sip a bit of Wonka's "fizzy lifting drink" on the sly, they are immediately lifted off their feet and into the air, floating among the bubbles. Falling with Kim Basinger from the top of one of Gotham City's gloomiest bell towers in the first Batman flick, a right-on-the-money shot from Batman's always-trusty grappling hook catches on one of the tower's gargoyles, stopping their fall and saving their lives. In "XXX," Vin Diesel races an avalanche down the side of a mountain on a snowboard — and wins. Let's talk about the marquee scene: A passenger bus successfully ramping a disastrous-looking 50-foot-plus gap in the freeway? The most frequent sci-fi physics sin is, without a doubt, the incredible sounds emitted by all those zooming spacecraft, all those exploding planets, all those laser beams whizzing by. In "The Day after Tomorrow," the scariest antagonists (besides the alien zombie dogs on board the abandoned cargo ship) are the roving "hurricanes" of sub-zero air that put anything that falls below the "eye" of the storm into a deep freeze. Granted, this calculation assumes a ton of ideal conditions, which almost certainly wouldn't exist. The telescope is so sensitive, in fact, that the National Radio Astronomy Observatory (NRAO) has a van that drives around the surrounding countryside asking people to stop using their wireless speaker systems, electric fences, broadband wireless modems, military radar, etc.
With the growing popularity of radio-array telescopes, the GBT may end up being the last single-dish telescope of its kind built in the world.
Above: The GBT is 485 feet tall, a nudge taller than the Statue of Liberty and a nudge shorter than the Washington monument. The 16-million-pound Great Big Telescope cost $75 million to build, but some would say it has already paid back the investment. The GBT Feed Arm (above, top right) is where all the radiation from the dish is reflected before being redirected to the receiver room. The only vehicles permitted on the NRAO property are diesels, from ancient pickup trucks and vintage Volkswagens to more-modern diesel autos. The GBT’s time is split into about one-third pulsar research, one-third astrochemical research and the rest a hodgepodge of mapping projects, including hydrogen clouds and various radar signals. The NRAO helps produce images like this: a giant bubble in the Milky Way Galaxy formed by the wind and radiation from massive stars and supernovae. It’s said the entire West Virginia University football stadium could fit inside the dish.
The surface of the GBT is made up of 2,004 individual panels, each of which can be adjusted to an accuracy of 0.3 millimeters.
Although the GBT can only run one receiver at a time, eight are mounted on this rotating turret above the receiver room.
Bob Simon, an Electronic Engineer at the NRAO, holds the new feed horn for a 7-pixel focal-plane array. The GBT whirls itself around full-circle in nine minutes on four sets of four-wheeled trucks. The entire control room is a Faraday cage, as in the movie “Enemy of the State” with Gene Hackman.
Like a giant dinosaur roaming the Earth, the GBT makes a profound impression on the landscape.

The goal of The Prepper's Blueprint is to help you find freedom through self-reliance, and ultimately, to get you and your family to a point where you can not only survive, but thrive, in a world that may be permanently altered.
Each day we are exposed to nuclear radiation, some naturally and some through un-natural means. Although the idea of preparing for an EMP or nuclear disaster is not something we want to think about, there are multiple ways to prepare, prevent and protect ourselves from the effects of radiation.
One of the easiest ways to minimize the effects of radiation is knowing where our food comes from and limiting our exposure to radioactive foods and water sources. An  electroscope that gauges how much radiation you are receiving daily can be a useful tool.


Thoroughly wash your produce. Despite arguments to the contrary, you can wash radioactive particles off of produce.
Adopting an anti-radiation diet can provide natural alternatives to assist the body in ridding itself of radioactive toxins. Any food or water stored in sealed containers that have any fallout dust is safe to consume as long as the fallout dust is brushed or rinsed off the outside of the container. If you are concerned about your water sources, use filtered water in everything, including brushing your teeth and sponge bathing.
Drinking apple cider vinegar can also assist in flushing toxins and  radiation from the body. Did you know that the Spiderwort plant is Nature’s gieger counter? This plant naturally has very dark purple flowers and when they are exposed to radiation or near an area where radiation is high, the flowers turn pink. Knowing in advance how much radiation you are  exposed to radiation through natural and un-natural means can help you calculate your annual radiation dose.
For a more in-depth look at what you should do if you are exposed to radiation, the symptoms of radiation sickness and how to prepare for this type of emergency, click here. This means that we would not only be without electrical power until transformers could be replaced, but that once they were up and running (a prospect that could take years),  all unprotected and unhardened electrical devices would be left useless and would eventually need to be replaced due to the circuits and boards being fried beyond repair. Over the course of this series, I have often emphasized the importance of being ahead of the pack in terms of preparedness. I have also stressed that it’s not about the preps that you acquire, but your skill level and knowledge with in working with what you have.
In conclusion, the threat of nuclear disasters and EMPs are real and we must prepare ahead of time in order to survive the aftermath.Having all of your items prepared and in place before the disaster will keep your family or group safe and ready to bunker in more quickly. For instructions on how to prepare for an imminent nuclear attack and how long to bug in place, click here. Do an inventory on your food, water and preparedness supply to see where you are in terms of short and long-term preparedness.
Consider purchasing more freeze dried goods (They last for 25 years, so it’s a great investment in your long-term preparedness). Find out if you are near a nuclear power plant and use the annual radiation calculator to see what your levels are.

Your map of nuclear power plants is not complete it does not show all the nuclear reactors in the US, there many small reactors that are being used for research by Colleges that are not on that list, for example the one at McClellan AFB near Sacramento.  Do some research and check in your area, you may be surprised by what you find. I would buy this in real bulk from someone else, (50-100LB) for the garden and make sure you research it as there a different types. Neither seems particularly fazed, as the two continue to grapple apparently unhurt on the ground and for the rest of the movie. This, presumably, is the result of all that carbonation inside their stomachs, increasing Grandpa and Charlie's buoyancy to the point where it can overcome the force of their own weight, lifting them into the air.
If you noted their painfully abrupt and inelastic jerk to a stop, though, you'd be onto something.
Unlikely as that is in itself, we as viewers are also treated to a direct shot of the gap in question, which clearly shows that the incline of the highway at the point of the jump is practically nil.
As every student learns very early on, sound waves need a medium through which to pass in the form of vibrations to be heard. In the film, these storms are said to derive their freeze-ray powers by rapidly sucking cold air (-100C) down from the Earth's troposphere to the surface.
As you've probably discovered yourself while in a building constructed with certain types of reinforced concrete, some materials have a knack for soaking up static electrical fields and sapping your cell phone reception — and copper is one of them. Brought to us by master-of-realism Michael Bay, this 1998 film is among cinema's worst physics offenders.
Most famous among these stellar students, especially in the sci-fi genre, is Stanley Kubrick and Arthur C.
Byrd Green Bank Telescope, depending on whom you ask) is the most overbooked telescope in the world. The difference between an array and a giant single-dish like the GBT is the difference between a zoom and wide-angle lens on your camera.
The 140 was out of service for a number of years, but has been brought back online in conjunction with an MIT project to study turbulent properties of the earth’s ionosphere. It’s offset from the center of the dish, so it doesn’t obscure any portion of the sky. Living this far out in the hills of West Virginia has been an adjustment for his wife, but she has adapted and has been honing her online shopping skills. Even as you make your way along the surface, it is almost impossible to grasp the overall size of the dish, and the shiny white surface makes it difficult to orient yourself. The room is filled with a loud racket from the helium pumps that keep the instrument in a temperature window between 10 and 50 Kelvins (442 to 370 degrees below zero Fahrenheit).
They are hoping to implement the new radio receiver this winter for ammonia mapping in the K band, between 18 and 26 megahertz.
The Faraday cage is used to keep the computer noise in and any radio-frequency interference out. The telescope can reach full elevation in four minutes on a shaft just 30 inches in diameter, which was specially designed to handle the 16-million-pound load. Because of the popularity of the series and the tons of great feedback we have received over the years, we took your advice and turned it into a full-fledged book.
Sometimes the part is played by the government, sometimes it is played by Mother Nature, and other times, the role is taken on by a random mishap. However, those who have observed history know this threat is real and should be addressed. Since the dawn of nuclear weapons, we have always been wary of a trigger happy world leader hastily pushing a nuke detonator. If you look back into history around 1859, you will read about a solar flare that was so intense that the explosion itself was visible to the human eye. Keep in mind that foods, especially seafood from the West coast will be the most affected by radiation. Foods such as kelp, rosemary, spirulina, miso soup and niacin all assist the body in fighting radiation damage.  Other foods that may help in combating radiation sickness are foods that naturally detoxify the body. Baking soda and water is another option as it also flushes radiation and cleans the stomach lining. You can also put baking soda in dish soap, body soap, laundry detergent as the radiation will bind to the baking soda which neutralizes it. Planting these in your yard will be a great way to know if you are taking in excess radiation.
A way to combat this issue would be to purchase or construct an enclosure made of conductive material that blocks both static and non-static electrical fields. The faster you can react to the disaster in front of you, the more quickly you can be prepared. Once an EMP outage occurs, your paper money will be worthless within a matter of days. Taking this a step further, in an EMP survival situation, you would be taking those skills and applying them to an off-grid environment. At this point, you should have a multi-level stock of preparedness foods to last long-term (up to 12 months). The well-rounded, multi-layered approach outlined in the Blueprint helps you make sense of a wide array of preparedness concepts through easily digestible action items and supply lists. Assuming speeds of 50 mph, a collision time of 0.015 second, and masses of 80 and 90 kilograms for Cruise and Scott, respectively, the force generated by the impact is an incredibly large 124,000 newtons, all exerted on the upper-right halves of the combatants' bodies.
Thanks to good old Archimedes' principle, we can calculate the amount of air that would need to be displaced to perform the lifting, and thus the necessary increase in volume due to the drink's carbonation of the bodies of Charlie and Grandpa Joe.
With Newton's second law (F=ma), we can calculate just how painful this "life-saving" shot may have been.
Hmm, so what exactly is keeping the bus from simply walking the plank, dropping to its fiery doom below?
Air, water, the membrane of your eardrum — all are sufficient media to transmit these vibrations. But what Dennis Quaid's professor character failed to consider was that the atmospheric pressure in the upper troposphere is roughly one-tenth of what it is on the surface. Whether built intentionally or not, this type of metallic shield is called a Faraday cage, after lifetime physics-hall-of-fame member Michael Faraday.


Let's try to tackle one of its most hilarious distortions of reality, the one at its core — that a nuclear warhead placed on an asteroid the size of Texas could successfully blow it apart, preventing a catastrophic collision with Earth. Hidden in the green hills of West Virginia, in a 13,000-square-mile National Radio Quiet Zone, is the world’s largest fully steerable telescope. The GBT is extremely good at finding a source in space by searching a wide area, while the radio array is like a telephoto lens that good at looking at the details. It can get mighty snowy and cold in this part of the world, which makes keeping the radio operating a challenge. The different receivers are used to detect radio frequencies, ranging anywhere from 1 gigahertz up to 90 gigahertz.
The humid West Virginia summers make it almost impossible to read the K band, as any moisture in the air blocks the signal, highlighting the minute nature of the information the GBT detects and the sensitivity of the instruments it uses.
The control room has some rather dated computers lying about, but we were assured they have plenty of computing power to get the job done.
The operators can look through windows covered with wire mesh to the GBT a couple of miles away.
Its size is in fitting proportion to the tasks that it undertakes, probing incomprehensible distances and documenting alien planetary phenomena. If we have learned one thing studying the history of disasters, it is this: those who are prepared have a better chance at survival than those who are not. Because of this, it's important to have a well-rounded approach to our preparedness efforts.
Foods that are high in potassium such as apples, oranges, pineapples and pomegranates are foods that are also good cancer fighters. For example, if you have non-working electrical appliances from the EMP detonation, you will be canning and preserving your food off the grid. People need to know how bad it will be if the grid goes down even in a relatively small region.
As you can see, to counteract the force of his mass (here we estimate his mass to be 70 kilograms), Grandpa would have to swell up to a massive 54 cubic meters-if he was a sphere, he would be five meters across (that's over 15 feet). And as we all know, the cold vacuum of space is unfortunately devoid of anything substantial enough to serve as a transmissive medium. As air falls to the surface and its pressure increases, its volume will decrease, as decreed by Boyle's law. Put simply, copper's conductivity effectively cancels out most electrical fields that come into contact with it, keeping the area inside a radio-free zone. Let's ignore the fact that asteroids don't have fault lines, and if they did, they would not be easily detectable. That's one one-hundred-millionth of the energy Bruce would need to save Earth — making this flick a bomb in more ways than one. In the famous opening segue from a prehistoric monkey battle to the space age, we see a giant circular space station slowly revolving. Due to the overwhelming nature of preparedness, we have created the Prepper's Blueprint to help get you and your family ready for life's unexpected emergencies. Chernobyl, being the first event, had a fire and explosion that released large quantities of radioactive contamination into the atmosphere, and spread over much of the Western USSR and Europe. For instance, the Fukushima nuclear disaster has already affected our food supplies, water sources, and even our health have become affected from the radiation dispersed into the water and atmosphere. Foods that are high in antioxidants will also assist your body in ridding itself of radioactive particles. Putting these numbers in real-life terms (what, you don't know what one newton of force feels like?) In car-crash studies, any pressure of that magnitude on the human body results in a 50-50 chance of surviving, with those who do survive coming away with massive internal trauma. For a more familiar reference, that's at least twice as big as poor Violet's sudden rotundity after sampling Wonka's experimental three-course gum. Batman would need to be packing some serious rope to hold up under such a force, but even if the rope didn't snap, a force of that magnitude applied in such a short amount of time would almost certainly break whichever bone the rope was anchored to, on top of causing massive internal injuries. The fastest recorded run on a snowboard (on a bobsled track, mind you — not loose powder like in the film) is 50 mph. At the time of the jump, Sandra Bullock manages to get the bus honking up to 70 mph, which means that in the time it takes to span the flat, 50-foot gap, the forces of gravity will have pulled the bus down at least 3.5 feet below the level of the bridge. It's true, however, that those unfortunate enough to have their spacecraft destroyed while it was exploding would certainly hear quite a racket for a few split seconds from inside, as the sound vibrations passed through the ship itself and into what was left of the cockpit's pressurized atmosphere as it broke up. Air masses are excellent insulators and relatively little energy, will leave the system during this volume change. Since the mesh surrounding Hackman's "Jar" is particularly fine, and because most radio and television waves have a wavelength of five meters or more, they aren't able to penetrate. Let's also put aside the fact that the prescribed 800-foot-deep hole in a Lone Star-size asteroid (Texas is 700 miles wide) would barely even scratch the surface, only getting you 0.0004 percent of the way to the center.
To make a more comprehensive, easy-to-follow program, The Prepper's Blueprint has been simplified and divided up in a way to help you make sense of all the preparedness concepts and supply lists provided.
The second largest nuclear event is the infamous Fukushima Daiichi nuclear disaster that occurred in 2011. Even when telegraphers disconnected the batteries powering the lines, aurora-induced electric currents in the wires still allowed messages to be transmitted. This ferocious geomagnetic storm was dubbed the Carrington Event. So you make the decision, are these types of disasters all hype or merely sensationalism?
Radiation tests conducted since the nuclear disaster in Japan have detected radioactive iodine and cesium in milk, beef and vegetables produced in California (Source).  This video is a great source that explains how radiation gets into our food supply. Foods such as green and black teas (make sure that your tea is not from Japan), garlic, cumin, nettles, dandelions, ginseng, lentils, collards and mustard greens are also suggested. Not only do Cruise and Scott survive the initial impact, they don't appear to have even a broken bone between them, when in reality, Tom would need a whole lot of nontraditional healing to recover from this one.
But Batman manages to do it all without even a wince — all the while keeping his grip around his lady's waist.
Powder avalanches travel down mountains at officially measured speeds of 130 mph on the low end, topping out at around 200 mph. Even given a set of impossibly ideal conditions — an optimistic two-degree incline in the road and disregarding air resistance altogether, the bus's rise and fall as a projectile will still only last around 0.22 second after leaving the ramp.
Because of the first law of thermodynamics, the work done to compress the air will be converted into energy, thus raising the temperature. Or that Bruce Willis and friends miss their landing site by 26 miles, presumably putting them away from the "fault line" anyway.
The shot stays put long enough to note that the station appears to be spinning at around one revolution per minute. But hey, I guess all those sound designers and THX-equipped theaters need to be used for something, right?
Let's just focus on the amount of kinetic energy needed to blow an asteroid apart, and for its two massive halves to move far enough (one Earth-radius perpendicular to the impact trajectory) to miss the Earth in the three hour and 56 minute time frame that marks this mission's absolute deadline.
Diesel the benefit of traveling at an unheard-of 80 mph, and track the avalanche at its slowest possible speed of 130 mph, how long before our totally extreme hero's apparent 10-meter head start is equalized? The radius of rotation also needs to be large enough for there to be minimal difference between the relative rotational velocity of a person's head and feet (something that — again — "Armageddon" fails to take into account). Under more conservative real-world conditions (accounting for some loss of energy from the system and the un-ideal nature of the atmosphere's gases), that figure would be around 0C, or a cool yet by no means freeze-ray-capable 32F. A quick calculation based on the 1rpm speed requires that the station have a diameter of 980 meters, or about the size of 10 football fields - huge, yes, but shown as such in the film. As some folks in the comments have pointed out, the fastest recorded run on a snowboard is actually upwards of 125 mph (set by Darren Powell in 1999). But still, considering an avalanche can travel anywhere between 130 and 200mph and an obvious lack of an aerodynamic helmet (or skin-tight speed suit, thankfully) on Vin, our money is still on the avalanche.
