I had been clambering with difficulty over a rocky hill near my childhood home, and found myself moving toward a large white nightshirt hung ominously from the electrical wires, as some kind of warning or portent.
Lawrence THE HANDLE, which varies in length according to the height of its user, and in some cases is made by that user to his or her specifications, is like most of the other parts of the tool in that it has a name and thus a character of its own.
I call it the snath, as do most of us in the UK, though variations include the snathe, the snaithe, the snead, and the sned.
Onto the snath are attached two hand grips, adjusted for the height of the user. On the bottom of the snath is a small hole, a rubberized protector, and a metal D-ring with two hex sockets. Into this little assemblage slides the tang of the blade.
This thin crescent of steel is the fulcrum of the whole tool. From the genus blade fans out a number of ever-evolving species, each seeking out and colonizing new niches.
I also have a couple of ditch blades which, despite the name, are not used for mowing ditches in particular, but are all-purpose cutting tools that can manage anything from fine grass to tousled brambles and a bush blade, which is as thick as a billhook and can take down small trees.
These are the big mammals you can see and hear. Beneath and around them scuttle any number of harder-to-spot competitors for the summer grass, all finding their place in the ecosystem of the tool.
None of them, of course, is any use at all unless it is kept sharp, really sharp: You need to take a couple of stones out into the field with you and use them regularly—every five minutes or so—to keep the edge honed.
And you need to know how to use your peening anvil, and when. When the edge of your blade thickens with overuse and oversharpening, you need to draw the edge out by peening it—cold-forging the blade with hammer and small anvil.
Probably you never master it, just as you never really master anything. That lack of mastery, and the promise of one day reaching it, is part of the complex beauty of the tool. Etymology can be interesting. Scythe, originally rendered sithe, is an Old English word, indicating that the tool has been in use in these islands for at least a thousand years.
But archaeology pushes that date much further out; Roman scythes have been found with blades nearly two meters long.
Basic, curved cutting tools for use on grass date back at least ten thousand years, to the dawn of agriculture and thus to the dawn of civilizations. Like the tool, the word, too, has older origins. The Proto-Indo-European root of scythe is the word sek, meaning to cut, or to divide.Future developments will also come from probing a scale one hundred times smaller than the cells in current silicon chips – the realm of quantum computers.
"Quantum computing is computation at the level of individual atoms, molecules and photons," says Artur Ekert, professor of quantum physics at the University of Oxford. The future is quantum Some of the most important technical advances of the 20 th century were enabled by decades of fundamental scientific exploration, whose initial purpose was simply to extend human understanding.
An Inherently Relativistic Force Carrier Mechanism for Unifying Electromagnetism and Gravity Based on Weber Electrodynamics. Authors: Steffen Kühn Comments: Pages. The report summarizes the current state of research of quantino-theory, which is an approach to explain fundamental physical phenomena based on Weber electrodynamics.
The Blog of Scott Aaronson If you take just one piece of information from this blog: Quantum computers would not solve hard search problems instantaneously by simply trying all the possible solutions at once.
Frank Wilczek won the Nobel Prize in Physics in for work he did as a graduate barnweddingvt.com book, Longing for the Harmonies, was a New York Times notable book of the year. Wilczek is a regular contributor to Nature and Physics Today, and his work has been anthologized in The Best American Science Writing and the Norton Anthology of Light Verse.
