Well it would depend how cold it would be, but I would say if it's below freezing cold, personally (when I go skiing actually) I would dress up in an under layer thing (I don't really know what you call it), a fleece sweater, (assuming there's snow) snow pants, and a jacket.
If you're climbing Mt. Everest, that's a whole different story.
One similarity between the Mayans and ancient Egypt is that both have developed a script without any outside influence, and that their script (the Hieroglyphs and the Maya script) are a combination of a syllabic and logographic script - some words have their own symbols, but there are also symbols for single sounds
There are many different touchscreens. Resistive, Capacitive, Infrared, Surface Acoustic Wave, Near field imaging, and Light pens. However, I am going to talk about Resistive, since that is the most popular in touchscreen technologies. They basically have a flexible upper layer of conducting polyester plastic bonded to a rigid lower layer of conducting glass and separated by an insulating membrane. When you touch the screen, you force the polyester to touch the glass and it will complete a circuit in the touchscreen. A chip inside will figure out where you touched the phone and send out an output.
