Dark Matter

By -
In an earlier post, I wondered, "Is ki real?" Is ki an actual thing, or is it just a concept?

I teach aikido to college students. So I hesitate to write about science as if I know anything, because I know I will be challenged! But I offer this:

Only a small part of the electromagnetic spectrum is visible to the human eye. We are all familiar with ultraviolet and infrared rays or waves and the ways in which they can be used: gamma rays, X-rays, infrared heat lamps, microwaves, and radio. Infrared light was only discovered by humans in 1800 and ultraviolet in 1901. But animals such as bees and snakes have sensed these parts of the spectrum for eons. How might a snake's ability to find prey or a bee's ability to find nectar have been described or understood before we had instruments to perceive these wavelengths?

Dark matter is a discovery that has only recently become known to non-scientists. Only 50 years ago, in popular culture at least, dark matter was the stuff of science fiction; in many ways it still is. As with infrared and ultraviolet light, its existence was originally postulated to explain observed behavior. We have since developed instruments that allow us to "see" and measure infrared and ultraviolet light, but we have nothing that will allow us to directly measure dark matter. Its existence can only be inferred based on the motions of galaxies and other astronomical "objects." Yet dark matter is estimated to account for 83% of the matter in the universe (maybe).  Astrophysicists seem to be overwhelmingly in agreement that dark matter's behavior is very strange, yet that something like it must exist.

So, given an awareness of the limitations of human understanding of how the universe is fabricated, does the existence of ki seem so impossible?

How to Make a "Rush" Woven Seat Chair Using Old Jeans (or Fabric Scraps)

By -

I used the technique for weaving a rush chair seat to make a chair seat using old jeans. The antique ladderback chair is just the right height for me to practice my Québécois button accordion. Fabric Choice Although at first I considered using t-shirt strips (also called tarn), I decided to jeans because denim is stronger and not stretchy. I had some old heavy linen fabric that would have done the trick, too, but I didn't have enough for the whole chair with either linen or jeans. I decided not to mix them, at least not for my first chair. I was advised, (correctly!) by other crafters, that all I had to do was out the word out, and I’d get donations. I sent out 4 emails and literally went shopping and there were two pairs of jeans on my doorstep. I had five more pairs by the weekend. (Now I need another chair!) Some Pointers Before I describe the process, here are some pointers. I don't recommend doing this with a stretchy fabric. Therefore, if you use jeans, avo...

Keep One Point

I've been slowly but surely writing of a series posts devoted to each of the  four basic principles of Kokikai Aikido . One of these is Keep One Point to Develop Calmness. We spend about 90 minutes in each aikido class, and most students practice once or twice a week - only a small proportion of the of hours we are awake each week. It may be plenty of time to spend doing a demanding physical exercise, but we need to spend more time working on the underlying principles for them to become second nature in our bodies. Fortunately, all of the basic principles are easily practiced at any time, not just in class. We can easily practice finding and keeping One Point while off the mat, and test the results when we're back on the mat. What Is One Point? One Point is a concept closely related to your center of balance. Centuries ago martial artists discovered that if the mind is focused on keeping this point low, one becomes stronger and harder to move. In Kokikai, we first...

What is Ki?

By -

The concept of Ki , or lifeforce, exists in many cultures. In Chinese it's Chi or Qi , in Sanskrit,  Prana . In western culture, while we may say someone has a soul that is distinct from their physical body, the soul is connected to the individual.  Ki, as it is understood in Japanese culture, is a universal force that permeates everything. Individuals may manifest more or less ki, but it is a connecting force between everyone and everything. In Japan, ki is an everyday concept that's found in many common phrases . For example the phrase "O  ki o tsuke te," which means "take care," literally means, "apply ki ."   "O genki desu?" the most common way to say "How are you?" means, literally, "Do you have ki ?"   "Ii k imochi," a phrase heard often, particularly in popular songs, means "(What a) good feeling." "Ii" means "good" and "kimochi" literally means having, o...
