Preface For over a decade I have taught an introductory, undergraduate class, "Einstein for Everyone," at the University of Pittsburgh to anyone interested enough to walk through door. With each new offering of the course, I had the chance to find out what content worked and which of my ever so clever pedagogical inventions were failures. At the same time, my lecture notes have evolved. This text owes a lot to many. i i i
Site Unavailable | UK2 - StumbleUpon Downloadable Computer Repair CDs One of our Technibble forum members, PcTek9, and a handful of other Technibble members have compiled a large list of CDs for various computer repair tasks. In this list, the following types of CD are available for download: Antivirus Boot CDs, Recovery Disks, Hardware Diagnostic Boot CDs, Network Testing/Monitoring, Data Recovery Boot CDs and Special Purpose CDs. Some of these are free to download, some are not. Be sure to read the EULA for the CD’s you download and the applications you use to make sure you are allowed to use them in the manner you plan to use them in. Also, some of these CD’s may set off an antivirus false positive due to their virus removal, password cracking, system file changing nature. Some CDs have been purposely left out of this list as they contain illegal software. Creating Multiboot CDs Many people have expressed an interest in creating a multi-boot CD or USB stick.

Free Java Tutorials & Guide Tips & Lessons > Fragmenting: A Quilt Design from a Single Block I often use fragmenting when designing quilts. The concept of fragmenting a traditional patchwork block is not new. It has been used for centuries with the traditional Lone Star design. In the Lone Star design, each of the diamonds of a traditional eight-pointed star has been broken up into the same number of smaller diamonds. Traditionally, each round of diamonds from the center outwards is the same fabric. When I developed the idea of fragmenting an entire design, I still started with a traditional quilt block. I developed Rajasthan from a traditional design called Beginner’s Delight. Fragmenting is fun. 1. 2. Divide each side of each shape into the same number of equal divisions. 3. For more detailed information on fragmenting, coloring fragmented designs and creating templates for each of the shapes, see pages 45 to 48 of my book, The Quilters Album of Patchwork Patterns. For other examples of my fragmented quilt designs, take a look at Mayflowers, Summer Lily, and Fabergé.
WannaLearn.com 6174 (number) 6174 is known as Kaprekar's constant[1][2][3] after the Indian mathematician D. R. Kaprekar. This number is notable for the following property: Take any four-digit number, using at least two different digits. 9990 – 0999 = 8991 (rather than 999 – 999 = 0) 9831 reaches 6174 after 7 iterations: 8820 – 0288 = 8532 (rather than 882 – 288 = 594) 8774, 8477, 8747, 7748, 7487, 7847, 7784, 4877, 4787, and 4778 reach 6174 after 4 iterations: Note that in each iteration of Kaprekar's routine, the two numbers being subtracted one from the other have the same digit sum and hence the same remainder modulo 9. Sequence of Kaprekar transformations ending in 6174 Sequence of three digit Kaprekar transformations ending in 495 Kaprekar number Bowley, Rover. "6174 is Kaprekar's Constant".
Top 10 Things You Can Upgrade with a Little Electronics Hacking it is a skill to do a good solder joint, it comes with LOTS of practice. so most people who rarely do it will ever get good at it. Bingo. Of course, part of the issue is having a soldering iron at the right temp with a properly tinned tip. I don't expect to ever master tricky stuff like smts or even multilayer pcbs so I'm not much better then a newbie, anyway - and I totally suck at sweating pipe joints. Ah, well... SMT is actually a bit better than through-hole once you get the hang of it.
Microparticles allow you to live without breathing Although it may seem like science fiction, a Boston research group has developed a type of microparticles which can be injected directly into the bloodstream to oxygenate your body quickly … even if we could not breathe. An extraordinary advancement in medicine that could help to save millions of lives in a year. According to the doctors, this development would allow medical teams to keep patients alive 15 to 30 minutes even though they may have severe respiratory failure. A time for medical teams in which they could act without risk for a heart attack or permanent brain injury. The first tests in animals are completed with a success. And from what these particles are composed? Particles of oxygen acids of two to four microns in size. According to John Kheir, principal investigator who solved the problem using deformable particles: We have engineered around this problem by packaging the gas into small, deformable particles.
