A broad definition of a tool is an entity used to interface between two or more domains that facilitates more effective action of one domain upon the other. The most 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 counterintuitive 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, sea otters, and others. 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. From Wikipedia under the
GNU Free Documentation License What equipment is needed to make a solar cell? Q. I was wondering what equipment it would take to under go something like that. Yes I do know it is not something cheap to just make. Thanks for any input. Asked by Mike - Tue Oct 28 10:26:06 2008 - - 2 Answers - 0 Comments A. If you search the internet, you'll certainly find ways to make very low power solar cells from common materials, but I'll assume that you want to make one with significant output. If you can somehow obtain solar grade wafers (or maybe you could just use the back of a regular semiconductor wafer if you can get one that's clean), then all you would need is a screen printer, the right chemicals, and a diffusion furnace. If you're at a university, and they have a semiconductor process lab, they may have all the stuff you need, already. A corporate lab (for example, at Agilent) would have this kind of stuff, too. If you wanted to do it at home, the cost would be prohibitive, and some dangerous materials would be involved.

There are often kit lists online on the military internet system, ask the orderly room where you would find the exact link. You will probably need to access it from a military computer. And lastly, get a grip on your kit soldier! Answered by Oot n Aboot - Wed Sep 10 16:25:43 2008 What is the equipment called that bends laminated pages so that the bend is clean?
