To disconnect a <a href="/title/main+canopy">main canopy</a> from a rig. Normally, one would only cutaway if the main is too dangerous to land. Who would want to cutaway a perfectly good canopy?
<p>
All modern sports rigs use a <a href="/title/3-ring+release">3-ring release</a> system to attach the main to the rig.

<p>
The length of a snivel is most effected by how well the <a href="/title/slider">slider</a> keeps the packed canopy out of the wind. The slider is attached to the <a href="/title/lines">lines</a> and is packed over the top of the open ends of the canopy. A larger and less porous slider lets less air directly into the ends of the canopy, increasing the snivel time. As the canopy inflates the lines are forced apart, pushing the slider down, which then exposes more of the canopy to wind.
<p>
<a href="/title/reserve+canopy">Reserve canopies</a> are designed to have a consistently short snivel. While some people like long snivels for soft opening main canopy, if a snivel is so long that the main has not inflated by the jumpers decision altitude they should consider it a malfunction, <a href="/title/cutaway">cutaway</a>, and use the reserve. If the snivel is too short the opening can be dangerously fast with the potential for damaging a person or gear with more force then they are designed to<!-- close unclosed tag --></p><!-- close unclosed tag --></p>…standing wave (thing)http://everything2.com/user/thecap/writeups/standing+wavethecaphttp://everything2.com/user/thecap2001-04-29T09:44:52Z2001-04-29T09:44:52ZA <a href="/title/wave">wave</a> with <a href="/title/nodes">nodes</a>, points that do not move. Created by two waves of equal <a href="/title/magnitude">magnitude</a> and <a href="/title/frequency">frequency</a> but opposite directions.
<p>
You can create a standing wave with a <a href="/title/rope">rope</a> by keeping one end fixed and moving the other end up and down. You create a wave moving away from you and it <a href="/title/reflect">reflect</a>s back from the fixed end, creating two waves of equal magnitude and direction but opposite directions. Each end of the rope is a node. If you double the frequency that you move the rope you will create a new node in the middle of the rope.<!-- close unclosed tag --></p>Running (thing)http://everything2.com/user/thecap/writeups/Runningthecaphttp://everything2.com/user/thecap2001-04-07T22:17:38Z2001-04-07T22:17:38Z<p>Training:

It is by far the most common film format for amateur photography, though digital cameras are improving in quality and becoming much more common. <a href="/title/Edison">Edison</a>'s <a href="/title/Kinetoscope">Kinetoscope</a>, invented in 1889, set 35 mm as the standard. Legend has it that when Edison was asked by his workers how wide to cut the film (which was manufactured by the <a href="/title/Eastman+company">Eastman company</a>), he held up his thumb and forefinger and said "About this wide."
<br>More probable, however, is that the 35 mm width was derived by just slitting in half the readily available 70 mm wide Eastman roll film (unperforated, used for still-pictures). Supposedly 35 mm film was once even called Edison size.</p>
