A tool, broadly defined, is an entity that interfaces between two or more domains; that facilitates more effective action of one domain upon the other. Basic tools are simple machines. For example, a crowbar simply functions as a lever. The further out from the pivot point, the more force is transmitted along the lever. A hammer typically interfaces between the operator's hand and the nail the operator wishes to strike. Tools are the most important items that the ancient humans used to climb to the top of the food chain; by inventing tools, they were able to accomplish tasks that their bodies could not, such as using a spear or bow and arrow to kill prey, since their teeth were not sharp enough to pierce many animals' skins. A telephone is a communication tool that interfaces between two people engaged in conversation at one level. And between each user and the communication network at another. It is in the domain of media and communications technology that a counter-intuitive aspect of our relationships with our tools first began to gain popular recognition. Marshall McLuhan famously said "We shape our tools. And then our tools shape us." McLuhan was referring to the fact that our social practices co-evolve with our use of new tools and the refinements we make to existing tools. Tools that have evolved for use in particular domains can be given different assignations. For example, tools designed for domestic use are often called utensils. Observation has confirmed that that multiple species can use tools, including monkeys, apes, several birds, and sea otters. Philosophers originally thought that only humans had the ability to make tools, until zoologists observed birds and monkeys making tools. Now humans' unique relationship to tools is considered to be that we are the only species that uses tools to make other tools. Most anthropologists believe that the use of tools was an important step in the evolution of mankind. Humans evolved an opposable thumb — useful in holding tools — and increased dramatically in intelligence, which aided in the use of tools. Carpentry tools recovered from the wreck of a 16th century sailing ship, the Mary Rose.From Wikipedia under the

Assuming the larger mechanical pieces are already in place and I have something of a moving blank slate platform, what do I do next? What materials, tools and supplies will I need to make something basic? Asked by Vern Masterson - Thu Jul 10 23:13:46 2008 - - 3 Answers - 0 Comments A. this is going to depend on what you are going to do for your float. Chicken wire is great for making forms, then you can paper mache over them. Insulation foam boards are good for things that are more structured and then you can carve that with various cutting tools.

Asked by Shinai - Thu Aug 21 16:01:42 2008 - - 3 Answers - 0 Comments A. To create a white background a blank space on a white wall can be used for a white background. Or a white sheet tacked to the wall will work too, but make sure it is not wrinkled, because the wrinkles will show and can be very distracting. Or paper or cloth backgrounds can purchased from a regular camera store, in any color imaginable and hung from a background stand that can also be purchased at the camera store. As well the backgrounds, you need lights, and a photographic umbrella. Ideally you should have three lights(either hot lights or strobe) a main light that is normally placed at 45 degree to the subject, a fill light that is normally placed next to the camera on the opposite side of the fill light, and a background light that… [cont.] Answered by rev.

Q. I asked this question a minute ago, I think in the wrong forum since I didn't get any good answers. I've found a couple tools that just make a big difference for me if I eat something healthy at home or else eat out or eat something unhealthy at home. Their ease of use and cleaning have made them top tools in my ability to eat healthier. Are there any ones that are just great for you to eat healthy, fresh foods at home? Answering my own question, here's what I like (despite what people said in the last question, this is not an ad!): For me, I love this chopper thing. The reviews on Amazon say that a lot of people's broke, but I've been using mine regularly for maybe 6 months now. I love it! It's so easy to chop on tomatoes and onions… [cont.] Asked by Cleoppa - Fri Sep 14 16:36:33 2007 - - 1 Answers - 0 Comments A. a bamboo steamer Answered by audioworld - Sat Sep 15 03:36:22 2007 From Yahoo Answer Search: "Tools"
