The same thing is to be understood of snow, and fine dust or powders, that are condensed by…
LAW I. Every body perseveres in its state of rest, or of uniform motion in a right line, unless it is compelled to change that state by forces impressed thereon. Projectiles persevere in their motions, so far as they are not retarded by the resistance of the air, or impelled downwards by the force of gravity. A top…

Lighting, cooling, heating, ironing, cooking, and entertainment at the flick of a switch. Cheap, silent, invisible energy at our beck and call, flowing though a wire. Magic. Wonderful. One of my…
