[her uses of the term Machine, see Machine (disambiguation) A machine is any mechanical or organic device that transmits or modifies energy to perform or assist in the performance of tasks. It normally requires some energy source ("input") and accomplishes some sort of work.People have used mechanisms and machines to amplify their abilities since before written records were available. Generally these devices decrease the amount of force required to do a given amount of work, alter the direction of the force, or transform one form of motion or energy into another.The mechanical advantage of a simple machine is the ratio between the force it exerts on the load, and the input force applied. This does not entirely describe the machine's performance, as force is required to overcome friction, as well. The mechanical efficiency of a machine is the ratio of the actual mechanical advantage (AMA) to the ideal mechanical advantage (IMA). Functioning physical machines are always less than 100fficient.

oth is an insect closely related to the butterfly. Both are of the order Lepidoptera. The division of Lepidopterans into moths and butterflies is a popular taxonomy, not a scientific one. Sometimes the names "Rhopalocera" (butterflies) and "Heterocera" (moths) are used to formalise the popular distinction. See more at Wikipedia.org...

is a handheld instrument used to write and draw, usually on paper. The writing is done with graphite (except for colored pencils), which is typically covered by a wooden sheath. Pencils may also have an eraser or "rubber" attached to one end, typically by means of a metal ferrule. The pencil differs from most pens in that erasing is possible. See more at Wikipedia.org...
