A tool is a device that can be used to produce or achieve something, but that is not consumed in the process. Colloquially a tool can also be a procedure or process used for a specific purpose. Tools that are used in particular fields or activities may have different designations such as Instrument, Utensil, Implement, Machine, Apparatus. Evolution of tool useAnthropologists 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. 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.

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.

Q. I recently built a new home. Tieing in the downspouts, final grading, and landscapping are all my responsiblility. I've obtained an estimate to have the work professionally done, but I think I can save a significant amount of money doing it my self. I've trenched downspouts before and planting and creating mulch beds is no problem. My question is, what is the best equipment ot use to move around the piled up dirt so I can great a smooth finished look? Asked by Dennis V - Tue Sep 18 09:46:31 2007 - - 4 Answers - 0 Comments A. I would give this a second thought. At least get the rough grade done by someone who uses the equipment every day and understands what the soil compaction is likely to be etc. The biggest cause of water in a basement is an improper grade. A huge pain, even if you just have a crawl space, as stagnant water breeds insects and mold etc. Finish grading can be done with hand tools if you have a lot of time and energy, but I would recommend letting the pros do this part as well. Stick to the stuff you don't need large equipment for, as even if you rent it, you don't have the hours using the equipment that the guys in the business have, and mistakes are a major pain to fix after your grass and flowers and bushes are in.
