The traditional way of taking a three-dimensional photograph, or hologram, involves splitting a laser beam in two, reflecting one half (known as the object beam) off the thing that is to be holographed, and then recombining it with the other half (known as the reference beam) and exposing a photographic film to the result.
The process of recombination produces an interference pattern that is recorded on the film, and when this pattern is viewed in suitable lighting, an image that looks three-dimensional becomes visible to the eye.
The Kogi or Cogui, or Kágaba, meaning "jaguar" in the Kogi language, are an indigenous ethnic group that live in the Sierra Nevada de Santa Marta mountains in northern Colombia. Their culture has continued since the Pre-Columbian era.
They have a message for the rest of the humans living on Planet Earth.
If you are planning to launch a home-based business or a small business, you might be having some thoughts about niche marketing.
First, you must decide what you want to do. If you're not clear on what you want to achieve, how can you set goals? So before you sign up at various sites, set up profiles, and jump right in, you need to make some decisions about what you want to achieve.
Science has a way of advancing at parallel times in different spaces (i.e. the same technologies that have historically been invented by two separate people in different locales at the same time).
Quantum experiments in the past have used beams of light to explore the working priniciples, and more recently two or more groups have demonstrated teleportation of quantum states of massive particles.
So this isnt the first time in my life that I've become excited about the prospect of Quantum Computing given the black-box nature of Shrodinger's notion that
*observing a system affects its outcome.
Since the most useful information derived from computing is the kind whose end state you can observe, I think of Quantum Computing as a complex rube-goldberg pendulum inside a box. You only get one result when you measure the system, but it's all the unknown paths that are of great value.
Sometimes I hear bits and pieces of song lyrics in my head. I find many of them to be particularly relevant, like Dave Matthews asking you "what would you say", or The Who exhorting you to "pick up your guitar and play".
Of course, it’s much easier said than done. There are so many other distractions, as well as necessary duties in life, that there is often little time left for anything unscheduled. As much as I love playing music, I often find that I need to have a goal in mind in order to make time to play.
The Massachusetts Institute of Technology has some of its course materials available online -- for free.
With an Internet connection and a Web browser, you can access MIT's pilot project: OpenCourseWare which includes the syllabus, lecture notes, exams (with answers), and videotaped lectures of 32 MIT courses.
Back in the Renaissance, the Italians used a term, "terriblisma," to describe the strange mixture of fear and excitement they felt when they were observing catastrophes that were on the scale of all so-called act of God disasters. Apparently, our modern culture has a more contemporary version of this emotionally complex sense of fascination with all things Dystopic.
