Sine Waves And FPS

Sound waves have an incredible ability to make other objects match their frequency. If you’ve ever listened to music with a heavy bass beat in your car, you’ve probably noticed the mirrors rippling when the sound waves hit them. What’s happening in the video above is essentially that, though the end result is much more dramatic.

A 24 Hz sine wave travels through a speaker under a water hose. The hose starts vibrating 24 times per second. When the water comes out, it forms waves that match the 24 Hz frequency. Here’s the trick though: Seen in real life, it would only appear to wave back and forth on its way to the ground.

The real hero here is the camera—the phenomenon of shifted perspective. By filming the falling water at 24 frames per second, the camera makes the water stream appear to freeze in midair. Each wave of water hits the exact same space, 24 times every second. On film, it seems like the same wave sits in the air indefinitely, when in reality a different wave has taken its place each frame. If you switched the sine frequency to 23 Hz, it would actually look like the water was falling upwards into the hose because of the tiny offset between the camera’s frame rate and the sine waves.


The Precepts As An Expression of Love

The Precepts As An Expression of Love

At first it may seem that the Ten Precepts are negatively expressed commandments, like the Ten Commandments of Christianity and Judaism. However, they do not say, “Thou shalt not…”but rather” There is no… .”That is, in the mind there is no killing, no stealing, and so on. This does not mean merely that you should attain to that kind of relative condition where you are pure, but that in the mind, which is the universe, the Buddha-mind, there is no killing, no stealing, and so on, from the very beginning. Some commentaries by Dogen Zenji on the Ten Precepts carry the verb, “must not,” but this can be understood to be for purposes of training. As a device, to reach realization that fundamentally there is no killing in the mind, you must not kill.

Even with their imperative implications, moral injunctions are expressions of love. It is an act of love, sometimes, to say, “Don’t do that!” Either way, as a presentation of unity with all beings or as a corrective device, the Precepts are expressions of compassion, so we can say that the Ten Precepts are simply ten different ways of showing love.

The Ten Precepts formulate the realization of inherent good. This good is not the opposite of bad. It is self-nature, Buddha-nature. All beings by nature are Buddha–only their delusions and attachments prevent them from bearing witness to that fact. The Precepts are a guide from self-centered delusion and attachment to the Buddha’s own full and complete realization of truth and compassion. They point the way to the fulfillment of your own Buddha nature. (p. 94)

1. No Killing. There is fundamentally no birth and no death as we die and are born. When we kill the spirit that may realize this fact, we are violating this precept. We kill that spirit in ourselves and in others when we brutalize human potential, animal potential, earth potential. We brutalize with a casual word or a look sometimes; it does not take a club or a bomb. War and other acts of organized violence, including social repression, are massive violations of this precept. It is ironic that sometimes one can be considerate of the feelings of friends and neighbors while working at a job that directly contributes to widespread suffering. At the other end of the scale, we find Jain monks who filter their water in an attempt not to harm microscopic creatures that inhabit it. Recent studies suggest that carrots and cabbages show responses to being cut or uprooted. What can we do? The answer is, I think, to eat and drink in the spirit of grateful sharing. I have heard that someone once asked Alan Watts why he was a vegetarian. He said, “Because cows scream louder than carrots.” This reply may serve as a guide line. Some people will refuse to eat red meat. Some people will not drink milk. Some people will eat what is served to them, but will limit their own purchases of animal products. You must draw your own line, considering your health and the health of other beings. (p.96)

The Electric Universe

Just call me Plasma Girl, I love this stuff. So electrically magnetic fractallishes!

NASA’s IBEX and Voyager 1 missions have shattered all conventional ideas about the heliospheric boundary, the region separating our solar system from interstellar space. In 2009, the IBEX spacecraft created the first all-sky map of the boundary revealing an astonishing ribbon of energetic neutral atoms. According to scientists, it’s still a big mystery. El
