This is the sequence of the nuclear criticality accident from "Fat Man and Little Boy" with John Cusack. This storyline was based on two real accidents that occurred early in the US's nuclear weapons program that killed two brilliant scientists. What happened was that he was checking the neutron flux, keeping the two halves of the plutonium core seperated with a screwdriver. The blocks around the sphere are tungsten carbide, a neutron reflector, and not lead. When the two halves went together, it achieved critical mass and emitted a huge surge of neutron radiation. The blue glow was caused by the air itself becoming florescent, like in a neon bulb. The doctor comments that he got over a thousand rads, and 600 is enough to kill. As brutal and horrifying it is, this is how one would die if they recieved that much radiation. One of the two scientists this was based on lingered for 26 days before dying, his skin peeling off dead and his internal organs shutting down.

2 Tips For Finding Cordless Drill Replacement Batteries Monday, November 29, 2010
Often it can be extremely difficult to find cordless drill replacement batteries, especially if your cordless drill is an older model out of production. It seems many stores do not carry older battery packs just to entice you to buy the latest new drill, well, lets not let that happen. This article is here to help you find a battery pack.
When you get frustrated looking for a replacement battery and end up at a dead end, use these two tips to get back on track.
Have the model number for your drill. This number should be located somewhere on your drill, and represents the serial number of the product. You can use this number to help you find the appropriate battery as many online stores list replacement batteries with the number in the listing.
If using the drill's model number doesn't work then a better idea is to find the serial number on the battery pack. Doing a search for this number almost always returns a good result.
These are just two tips on how you can better your search for cordless drill batteries. Looking for one can be frustrating, but perhaps the most frustrating part is having to pay an arm and a leg for a new battery pack. I guess when a seller knows you need it badly they think they can charge a hefty price for it.
It definitely isn't fair to have to pay so much for a new one, but other than finding one somewhere for cheaper than other places you could always try to revive your battery. There are a couple of how-to's out there that show you exactly how to revive a battery back to life. One video I saw used a welding tool to juice it back up.
If you know where to look then you can definitely find a pack for cheaper. I know of one place where you can find cordless drill batteries for cheap (which just goes to show how many places are overcharging...). It also has some helpful tips on how you can restore your battery back to life and save some money. All in all its just an excellent place to visit for your cordless drill battery needs.

Power Tools History Saturday, November 13, 2010
Since the ancient Egyptians began using a hand-powered lathe centuries ago, man has striven to make arduous building and assembling tasks easier, quicker, and more efficient through power tools. We've come a long way from those sand-covered turning machines, but the end goal is no different from our desert-dwelling ancestors. Today, nearly every home in every industrialized country houses and uses power tools.
Even though the concept of the power tool has been around for a long time, it wasn't until the late 1800's when the first modern-era power tools became possible. The advent of electric motors made highly-efficient stationary and portable power tool technology a reality, and high-speed assembly lines made power tools both affordable and profitable.
The Bosch company was at the forefront of power tool technology in those early years. Founded in 1886 Germany by Robert Bosch, the company initially focused on automobile components with integrated electric parts, and was responsible for such developments as the first low-voltage magneto ignition. Before long, companies in other industrialized nations began developing the first electric power tools, and Bosch introduced its first power drill in 1932. Today, Bosch still engineers and manufactures automotive parts, and its power tool division has grown to include nearly every household and assembly tool on the market - including power drills, belt sanders, circular saws, and more. As part of the company's growth, it has acquired other successful power tool manufacturers that started during the same early 20th century era.
In 1923, American inventor Raymond DeWalt introduced the world's first radial arm saw, a sliding circular saw that could make long cuts with accuracy. One year later, he founded the DeWalt power tool company in Baltimore, Maryland; another company that has grown substantially over the last 85 years. At the forefront of portable power tool technology, DeWalt's power tools are revered by carpenters and homeowners alike for their long-life, durable cordless battery-styled power drill, circular saws, and other power tools; and the company currently manufactures over 200 types of power tools worldwide.
Founded in 1915 in Japan, the Makita Corporation has also staked its reputation on cordless, battery-powered power tools - most notably, the hand-held drill, which Makita introduced in 1978. Nine years later, the company had a full arsenal of cordless, professional-grade power tools for contractors. Today, Makita manufactures over 350 different power tools, both portable and stationary, and the pronounced teal color emblazoned on all of their tools is often mimicked by others trying to capitalize on Makita's reliable name.
The early 20th century proved to be a hotbed of power tool advancements, and many companies worked hard to develop profit-turning innovations that moved their products off store shelves and into people's homes. While the term power tool traditionally conjures thoughts of electric drills and sanders, machines like the pipe threader and utility pump are also considered power tools. This is the area the Ridgid company focused on when it was founded in Elyria, Ohio, in 1923. Still a leader in the plumbing tool industry, Ridgid now has a power tool division that focuses exclusively on contemporary power tools and has released its own saws, drills, and even air tools.
A.F. Siebert founded the Milwaukee Electric Tool Company one year later in Milwaukee, Wisconsin. Known for manufacturing heavy-duty power tools, Milwaukee is best know for the 'Sawzall,' one of the most widely-used reciprocating saws in the world. Like their power tool manufacturing competition, Milwaukee currently produces portable and stationary power tools like circular saws, drills, band saws, grinders and sanders - over 500 different models in all. Unlike their competition, many of Milwaukee's power tools are released in both 120 and 230 volt models, drawing the line between household and commercial/industrial power.
Best known for the Skilsaw they invented in 1924, the Skil power tool company evolved out of the Michel Electric Handsaw Company when they entered the power tool market. Fueled by the ingenious circular saw invention, the company elevated itself to the upper echelon of the small power tool industry with jig saws, grinders, sanders, and a whole slew of handheld, cordless power tools. In 1996, the Bosch company purchased Skil but still keeps its power tools on shelves worldwide as one of the most popular power tool lines on Earth.
The Delta company has changed hands several times since it was founded by Herbert Tautz in 1919 in his Milwaukee, Wisconsin garage. Tautz focused on small tools but when Delta was purchased by Rockwell in 1945, the company made a profitable shift to the stationary tools - like planers and bench sanders - it's renowned for today. Delta isn't the only name this line has carried, however; Rockwell enveloped the company on takeover before selling it to Pentair, which re-introduced the Delta name before selling out to Black & Decker in 2004.
A veritable power tool power house, the Craftsman brand was coined by the Sears company in 1927. At first, the company primarily manufactured common hand tools like hammers and screwdrivers; but soon jumped on the power tool bandwagon and is now one of the top-selling producers of all power tools, both stationary and portable.
S. Duncan Black and Alonzo G. Decker founded the Black & Decker small machine shop in 1910 in Baltimore, Maryland; and the duo found their niche in the power tool industry by inventing the electric drill seven years later. The pistol-grip and trigger style drill became popular and is now a staple on construction sites and in households alike. Realizing the profit potential of power tools, Black & Decker has grown and acquired several other popular power tool brands, including DeWalt, Porter Cable, Delta, and Kwikset.
As industrialized nations become increasingly technology-driven, power tool production stands to increase as lightweight, powerful, and longer-lasting batteries try to match the power and reliability of corded power. Versatile contemporary models and thousands of accessories continue to make everything from woodworking to metal machining easier, more efficient, and more profitable for manufacturers, contractors, and homeowners alike. As power tools have become affordable for nearly everyone, only the hammer has resisted an electric redesign destined to change the way we work forever.

SDS Hammer Drills Monday, November 1, 2010
Bosh Company first introduced the SDS hammer drills or Special Direct System Drills in the year 1975. These equipments are very much similar to regular hammer drills but in a more improved and developed sense which allows the later to have more power in terms of hammer blows. To function well, a user should need SDS drill bits that makes hammer drills safer in terms of minimizing hammer slips.
As a comparison, the normal hammer equipments have to moved the entire whole drill chuck in order to produce hammer action whereas when using an equipment, user will only have to allow the bits to move inside the chuck, which allows power to direct accurate and efficient work. The SDS hammer drill is far better when it comes to performance drilling of objects like concretes.
There are absolutely a lot of advantages when it comes to hammer drills. One SDS hammer drills is far beyond the normal equipment when talking about hard drilling jobs. The hammer can drill 90% through an object and finishes the job more quickly than any normal drills. As compared to a normal drill, you will be able to finish ahead when using an equipment.
In addition, SDS drills are controlled through different modes. When you want to drill in normal speed without much action, you can opt for a maximum speed of 1500RPM slower. You can also choose hammer only mode or often called "roto stop". When using this, you have to fit a range of SDS chisel bits or even use the equipment in micro drills like a concrete breaker. This mode is best opted for light drilling action, removing tiles or bricks, or even creating socket cut-ins or cable runs.
You will also be surprised at how an hammer equipment can be so much quieter than any normal hammer when drill provides that SDS drills have better and tough performance. There are also safety clutches provided by hammer equipments like the ability to cut the power of the drill once it jams in any object being drilled.
When looking for a better and ideal drill, you have to look for the ideal weight, which is usually 2kg and up to 4kg. There are also low end or budget SDS drills but they are much heavier than the good ones.
Additional features of drills include speed control that can allow you some bit of control when it comes to handling and drilling specific and various objects. There is also the rotation lock control that allows user to lock the chisel so it won't be moved once a user decides to drill into an object thoroughly.
When using an drill the first time, you should be extra careful in drilling walls as it may collapse because of the power drill brought about by drills. It would be best to equipment some holes first to avoid this kind of problem. It is suggested that to give a maximum power, drill a bit in the title with an inch or 1 1/8 inch. However, under power drill will result if there are bigger equipments bit.
