I have a pretty nice hammock, sturdy cast iron construction and the hammock itself has about 40 individual strands of rope connecting it to the hook. I lie there thinking about load bearing and directional forces and whatnot. With the number of individual redundant points of failure, I think I'm pretty safe.

This sort of design. But a better one.

> More people hammock - very nice colors

Haven't tested to find out what the definition of "several" is yet.

Be safe in your hammocks, people. Respect the hammocks, and they will respect you.

Mess with them, and they'll fuck yo' shit up, fo' sure.

TL:DR: X Rays heat the air surrounding a nuclear explosion at nearly the speed of light, into a nearly perfect sphere of super-heated air. The volume of this sphere is dictated by the yield of the bomb.

From Richard Rhode's Pulitzer Prize winning, "The Making of the Atomic Bomb"

> ...The radiant energy loosed by the chain reaction is hot enough to take the form of soft X rays; these leave the physical bomb and its physical casing first, at the speed of light, far in front of any mere explosion. Cool air is opaque to X rays and absorbs them, heating; "the very hot air," Hans Bethe writes, "is therefore surrounded by a cooler envelope, and only this envelope"-hot enough at that-"is visible to observers at a distance." The central sphere of air, heated by the X rays it absorbs, reemits low-energy X rays which are absorbed in turn at its boundaries and reemitted beyond. By this process of downhill leapfrogging, which is known as radiation transport, the hot sphere begins to cool itself. When it has cooled to half a million degrees-in about one ten thousandth of a second-a shock wave forms that moves out faster than radiation transport can keep up. "The shock therefore separates from the very hot, nearly isothermal [i.e., uniformly heated] sphere at the center," Bethe explains. Simple hydrodynamics describes the shock front: like a wave in water, like a sonic boom in air. It moves on, leaving behind the isothermal sphere confined within its shell of opacity, isolated from the outside world, growing only slowly by radiation transport on this millisecond scale of events."

> What the world sees is the shock front and it cools into visibility, the first flash, milliseconds long, of a nuclear weapon's double flash of light, the flashes too closely spaced to distinguish with the eye. Further cooling renders the front transparent; the world if it still has eyes to see looks through the shock wave into the hotter interior of the fireball and "because higher temperatures are now revealed," Bethe continues, "the total radiation increases toward a second maximum": the second, longer flash. The isothermal sphere at the center of the expanding fireball continues opaque and invisible, but it also continues to give up its energy to the air beyond its boundaries by radiation transport. That is, as the shock wave cools, the air behind it heats. A cooling wave moves in reverse of the shock wave, eating into the isothermal sphere. Instead of one simple thing the fireball is thus several things at once: an isothermal sphere invisible to the world; a cooling wave moving inward toward that sphere, eating away its radiation; a shock front propagating into undisturbed air, air that has not yet heard the news. Between each of these parts lay further intervening regions of buffering air.

edit: This book is my most recommended read of all time, hands down. It is an epic work of history, but at many points reads like a Tom Clancy thriller. It details the political, scientific, and intensely human developments that's end result is the atom bomb coming into the world. It won the Pulitzer for a reason.

For a more strictly scientific explanation, this page is great: http://www.abomb1.org/nukeffct/enw77b3.html

They use to come with it free? Well shoot, sony is sounding better and better. I had to pay for my nikon remote, it was only 12$ brand new tho, hardly a break deal.

Not sure how the sony remotes are, but my Nikon remote is about the size of a small pack of gun, I've lost is so many times; I decided to take a lense cap leash like this and attach it to my remote. Now I can have my remote dangling from my wrist when I shoot, never loose it now :)

Well, I think we should all read some poems. I feel as if the cover photo for Ballistics is from the same photographer: http://www.amazon.com/Ballistics-Poems-Billy-Collins/dp/1400064910

On a semi-related note, I picked this book up a week or two ago after reading an insightful comment on Reddit

http://www.amazon.co.uk/Thinking-Fast-Slow-Daniel-Kahneman/dp/0141033576

Has some very interesting research about how our minds work, how we instantly recognize things without knowing why or how, and the ways it can deceive us. Recommended.

Try the type of activewear leggings/shorts that have the specific phone-sized pocket on the thigh, like this.

You could get a short longboard. I have this one, and you can at least kick-turn it. Other tricks are a bit beyond me, though.

Original video link.

Buy the book because I said so. I am in no way, form, or matter affiliated, related, nor paid for by fenton's master and such relevant persons and/or companies.

If you look up 'misogyny' in the dictionary, there's a picture of pants with fake pockets, or pockets that have been sewn shut.

(Which is why I wear one of these.)
