A recent post here about thawing permafrost releasing climate-warming carbon dioxide into the atmosphere was no exception. As CO2 has had no noticeable effect on climate in million years, until 20 years ago, when carbon tax was invented, any alleged climatic effects can be ignored. I ordinarily ignore comments like the one I quote above. Discover is a science magazine, not a platform for political grandstanding.
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. Sek is also the root word of sickle, saw, schism, sex, and science.
Some books do that, from time to time, and this is beginning to shape up as one of them. By his own admission, his arguments are not new.
But the clarity with which he makes them, and his refusal to obfuscate, are refreshing. I seem to be at a point in my life where I am open to hearing this again. Here are the four premises with which he begins the book:This is the third article in a four-part in a series on Aristotle’s three modes of persuasion.
In a two horse race, emotion, not reason, wins the race. Emotion defines debates — those who make the most emotionally persuasive argument win. Goldsmiths, University of London is in South East London. We offer undergraduate and postgraduate degrees as well as teacher training (PGCE), Study Abroad and short courses.
In the world, there are alternative fuels being developed to replace the use of gasoline and oil dependence.
Besides replacing gasoline and oil dependence these alternative fuels are here to prevent pollution from occurring, to stop pollutants from getting into the atmosphere and affecting the.
(used relatively in restrictive clauses having that as the antecedent): Damaged goods constituted part of that which was sold at the auction. (used after a preposition to represent a specified antecedent): the horse on which I rode. (used relatively to represent a specified or implied antecedent) the one that; a particular one that: You may choose which you like.
Sep 06, · The sun is the ultimate source of energy for our planet. Its energy is found in fossil fuels as well as all living things.
Alternative fuels are considered to have a less adverse effect on the environment, and are stated to be a solution to the problems created by fossil fuels (SEP, ). Alternative fuels, such as ethanol, methanol, and biodiesel may prospectively provide an alternative for global fuel requirements. This free Environmental Studies essay on Essay: Use of fossil fuels and global warming is perfect for Environmental Studies students to use as an example. I for one think this is a great change, and a brilliant post. Absolutely, less time delightedly exploring still more abstruse mistake-theory-legible problems (although these are fun and the theory that total unity is possible feels good) in favor of more time spent on projects such as, “which candidates are really fighting for the people vs. just astroturfed shills” hear hear!
Harnessing its energy holds great promise for the world’s energy needs, and it will be heavily called upon as fossil fuels are depleted. OPEC publishes monthly production data for all OPEC nations in their Monthly Oil Market ashio-midori.com data crude oil production only and does not include condensate.
I have found the data to be highly accurate and any errors are corrected in the next month’s report or the month following that.
