  • Computer Chips Built Atom By Atom-Nanotechnology, Medicine, and Computer Circuits of the Future

    Nanotechnology describes the science of the development and manufacture of materials and products that are only a billioneth the size of a nanometer

    A nanometer is approximately a billioneth the size of a meter. A more exact term for this science is molecular nanotechnology because often the term is commonly used to describe the manufacture of items very small when in actuality nanotechnology only applies to technology being developed within the molecular scale of about 100 nanometers or smaller.

    Product Manufacture

    The Top-Down Approach - The ages old convention of utilizing larger objects to  direct the construction of smaller components.

    The Bottom-Up-Approach- Seeking to arrange smaller components such as atoms into more complex assemblies.

    (To be completed at a later date.)

  • Optical Computers-Light signals, Not Electrical Current Can Redefine the Computer

    The September 3, 2009 issue of Science Daily harbored a fascinating article called "Super-fast Computers of the Future". Computer information will be transferred in the form of light signals instead of via electrical currents. Queens Universlty Belfast and Imperial College London are the lucky academic entitites that got funded for the research. The challenge lies in the realm of the developing science of nanotechnology, the science of manufacturing parts and devices at the molecular level to function in the world of computer engineering.

    "Nanoplasmonic" devices are no bigger than 100 times the width of a human hair and are divided in the categories of "wave guides" to help the light signals navigate their way through the tiny components; and signal receivers and detectors to "catch" the data after their journey through the computers processor has been attained. Currently, nanoscale metal devices in computer processors work with electric current, but the new devices have been designed to interact with light in an unusal and highly controlled way which make it possible to use light signals to compute data.

    These processors will become known as "optical computers" based on their utilization of light. The prediction is that they will be much faster and more efficient than what is at our fingertips today.

  • Why Linux Is For Me

    How do I want to relax? I want to fix up my old 2000 HP Computer.And make it strictly a programming computer. Want to install Visual C on it and get to work on that transportation /highway safety/accident prevention program I started years ago.

    Now, for my operating system I want to choose Linux, but I haven't decided on the version yet. I was trained on Red Hat Linux in the nineties. Now, why Linux and not Windows? Windows is for users of PC applications, Linux is for programmers. Period.

    Programmers like the flexibility. Programmers like access to the kernel that runs the operating system. The Windows operating system is sold to you "as is", and it's what you get. Good luck to ya if you ever wanted to modify the code.

    Also, programmers want to see the command line. Having taken my first programming course back in 1985, well, I'm just used to that command line. I hail from the "old school" of DOS.

    Programmers want greater network flexibility and Ddase management.

    Programmers want to do fancy things with their desktop. The Windows desktop is pretty standard.

    Licensing is an issue for many programmers but not for me. I don't ever intend to sell anything that I modify in the kernel. But since Linux is free, it is also free of the licensing restrictions imposed by Microsoft.

    So, being programming minded, which "distro" do I choose? Should I download Ubuntu from the Internet or purchase a Caldera cd complete with manual? The kernel is the same in all the distributions, aka "distros" but the software add-ons and installation processes vary .

    So now I need to decide what I can live with or live without. The search for the right "distro" for me is on.

  • Internet Gems-If You Want to Practice Your Math Skills For Free, Try These

    Ok, Shiropan, I promised you this research project. A list of resources regarding algebra, I found the website www.purplemath.com. I found the link to West Texas A& M's Virtual Math Lab at www.wtamu.edu under the "Free Online Tutoring and Lessons" link.

    The Virtual Math Lab covers help for elementary algebra, intermediate algebra and college algebra. There are practice tests with answer keys at the the end of their lessons. I also checked out sites under the Other Useful Sites link and found references for using graphing calculators and studying for tests.

    I am making use of this Virtual Math Lab site at this time, but I will be researching and utilizing other online resources material as well, which I will fill you in on.

    That is the great and fun thing about the Internet, you can find virtual guides to improve your study skills without having to leave your house. Didn't have these resources when I was in college, cause the Windows interface did not exist back in 1985. I remember utilizing the DOS-based systems (man, I am dating myself!) and taking beginner programming languages in PASCAL and FORTRAN-can you imagine that? Life before Bill Gates!

    I remember taking my first computer progamming class in 1985 in the basement of the Casper College administration building. Ralph Anderl was my teacher and he was so sick of being stuck in the basement with those dinosuar computers.

    I was nineteen, so you probably would have been about six or seven years old at the time. I didn't grow up with a Windows interface, so now I am remembering when we didn't have it, but would like to play around with Linux again like I did in the past. (That's been a while.) I am now hitting the Linux resource guide sites.

    You see, I am a geek that way and at times I like being by myself so I can indulge in my "geekdom" without multiple condenscending quips from people who don't care to try to understand why I enjoy this stuff.

    But not all the time. And not forever. Just when I want to be by myself. I think everybody needs and should get their space just to be themselves sometimes. Not like its a bad thing.

  • Sign Me Up, Too-I'm Goin' Back to School

    Today I marched up to Casper College (you'd be proud of me, Shiropan!) and grabbed myself a fall class schedule.I plan to return to night school and get ready to pursue one of my dream professions. I always wanted to become a veterinarian or a quantum physicist.

    I already hold (2) degrees, a B.A. in forensic anthropology and and A.A. in paralegal studies and now, after being a paralegal for years, I am working in detention and plan to try out for the city police force again soon. But I got the last degree about (13) years ago and my EMT certification (4) years ago.

    Now one thing I am passionate about doing and need to do is sign up for Calculus. That would get me (3) credits closer to my computer science degree, which I started about (12) years ago.

    However, I took my last math class (15) years ago and I never used any math at all as a paralegal or an EMT. I don't think I remember enough college algebra and trigonometry to succeed at Calculus at this time. So I am considering rectifying this situation by taking the COMPASS exam after hard review and practice of math this summer.

    First, I need to collect all of my former college textbooks, regularly attend the college math lab after I get off work at 2:00 in the afternoon and scope out all the Internet resources and study guides I can. Then when I get as reviewed as possible, I plan to take the COMPASS exam and see if I can avoid taking college algebra and trigonometry over again. Then I can get Calulus out of the way and meet the mathematics requirement for any degree I want.

    So here is where my academic focus lies at this time. To prepare to take the COMPASS exam and see if I can take Calculus.
