Making Electromagnetic Weapons: Flashlamp Lasers
In my second article of the laser weapon series (see the first part here on CO2 lasers), I'll be expanding on the potential of pulsed lasers.

If you take two flat mirrors and place them front to back and look at them, you can see an infinite number of reflections. While this is a self-replicating pattern and can be somewhat mesmerizing, it isn't anywhere as interesting as looking at the chaotic scattering of light that can occur between 3 or 4 spheres.
Combine a bunch of fractal objects with mirrors and and lights and the ability to walk around inside and you get something like the image below.
Fashion designer Andreia Chaves of São Paulo has created some optically stunning, "invisible" shoes. Constructed with mirrors, the shoes blend into their environment, chameleon-style.
Congratulations to Matt White for "self medicate", the winning photo for this past week's Phone Snap Self-Portrait Challenge!
The first thing you need to do in case of any emergency no matter what it is, it would be make a family plan you need to be aware on what are you going to do and this is not no option. Emergency's happen all the time it could happen right know or it may occur tomorrow it does not matter when it happens your suppose to be prepared already.
ApartmentTherapy reminds us of a fine fix for scratches on glassy surfaces like mirrors and windows—toothpaste!

Swedish interface geeks The Astonishing Tribe predict what kind of touchscreen technology we'll be using in 2014 (that would be approximately 3 years, 4 months from today): Eek, that first movement that occurs around 0:25 (he pulls the screen to the right, extending it's width) is trippy. In a great way. The Astonishing Tribe says:
Interested in taking a few snapshots of the likely auroras from the recent solar flare the Sun sent our way?
Eric Jacqmain is one smart cookie. Borrowing from the same principles of Archimedes’ mythological death ray, the Indiana teenager used an ordinary fiberglass satellite dish and about 5,800 3/8" mirror tiles to create a solar weapon with the intensity of 5000x normal daylight. The powerful weapon can "melt steel, vaporize aluminum, boil concrete, turn dirt into lava, and obliterate any organic material in an instant."
Sometimes the "nasty bits" are unexpectedly yummy. With a reputation for being both cheap and reliably good, Chichi Wang of Serious Eats describes chicken's feet:
Skoda has created an amazing car constructed with CAKE! for their latest advertisement. Via Car Pages,
Turn on the ceiling fan indoors during the cold winter season. Though it may seem counterintuitive, spinning the blades clockwise on a low setting actually recirculates warmer air trapped near the ceiling towards the floor.
Just dried a load of laundry? Don't throw away that used fabric softener sheet just yet. You can repurpose a used sheet for a variety of practical uses around the home, such as picking up pet hair from your furniture, deodorizing your gym bag, removing static cling from your stockings, and adding shine to your mirrors and toaster.
Are you in dire need of some visual eye candy? Dazzle your eyes by building your own kaleidoscope with a sheet of foldable plastic, common household items and whatever small and sparkly things you can get your hands on.
Conceptual artist Michel de Broin has created the biggest disco ball the world has ever seen, which he suspended over Paris for one night.
You might already know a little bit about what the National Ignition Facility has been up to lately, or what they could possibly achieve. But last week, even the scientists at the Livermore, California station couldn't predict the awesome power that their humongous laser was capable of. NIF's laser is already the record holder for the world's largest laser, and now it can also claim to be the first ever 2 megajoule ultraviolet laser after it generated nearly 100 times more energy than any oth...
On October 7th, the IndieCade Conference will open its doors to some of the most innovative minds in the independent gaming industry. The three day event located in Culver City, California includes presentations by notable indie designers, workshops, galleries, and mixers. On the following day, however, the IndieCade Festival begins. Unlike the conference, the festival includes events targeted at gamers and the general public. While a $15 wristband will grant you access to keynotes, events, a...
There's still about eight months before the final chapter in the Mass Effect series comes out, but some trigger happy fans are already building replica costumes and prop weapons to celebrate the upcoming release. BioWare themselves recently commissioned some of these projects, which were shown at their booth at Comic-Con 2011 a couple weeks ago in San Diego. One of these projects was the armor that turian Garrus Vakarian sports in Mass Effect 3, by Kommissar Props. But even more impressive wa...
Self-driving vehicles may be the apex of safe driving, taking human error out of the equation. Until then, augmented reality can help reduce accidents by improving driver awareness.
Other than helping you make your morning cup of joe, coffee filters have a number of surprisingly practical uses that have nothing to do with coffee.
Today's fancy cars come with all sorts of options, from power mirrors to working seat belts. Some of us condemned to live in the reality of capitalist recession have no car, or perhaps a very modest one. But your modest car can still have some cutting edge technology wedged into the trunk and dashboard if you know what you want and where to look for parts. Today, we make a parking sensor using a sonic range finder, just like in the vehicles our owners drive!
File Transfer Protocol, or FTP, is a network protocol made for transferring files in a client and host fashion over a Transmission Control Protocol (TCP) network, such as the internet. FTP is integrated into most browsers, and you have probably used it before. It is a common way to host files and transfer them easily. To access an FTP, a login is required, unless the server is configured to use anonymous logins (like the Arch Linux mirrors).
It's Monday, and once again it's time to highlight some of the community submissions posted to the Math Craft corkboard. In addition, I thought we'd take a look at having fun with the geometrical properties of polygons and circles by using one of the best circles I know, the penny.
Let's face it, not every logophile is addicted to Scrabble. Without the use of a timer, Scrabble can be a pretty slow game. Even in clubs and tournaments where the standard time limit is 25 minutes per person for a two-player game. Now, take away time restrictions and add two other players and you've got a game that could take up to 2 hours! It all really depends on who the competition is.
This article will show you how to make a proportionally correct 1/187 (about) size Hubble Space Telescope. I tried to add as many details as possible, but it was hard at such a small size. It was really easy, but it did take a while to make.

have a maze with lots of clear windows or mirror doors put some in their then relase alot of bees ,and while thier runung they be crashing into the windows/mirrors and when they come out of the maze shoot him with some paintball gun then it him with a big ball
My idea is simple but, imo, funny. Have the gang have an all out laser tag war with running, diving, obstacles, the works, in a padded arena or outdoors. But each harness is connected to one of those flat tasers (the kind that looks almost like brass knuckles) pushed in their backs, or chest, or crotch (or all three if you prefer, each one connected to a different sensor: back shot is back shock, front shot is chest shock, head shots are crotch shocks). When you get shot you get shocked. It w...
