comment If there were fundamental forces weaker than gravity, would we know about it?
@Void The arrow clearly points outside of Slovakia, somewhere in Poland. Moreover, the entire rectangle around the "landscape" is understood to be the "swamp", not only some small area near the tip of the arrow.

comment Why are radiators always placed under windows?
@PPG Yes, but your desk has space underneath for the air to flow and probably some clearance from its edge to the legs. If there is a radiator or baseboard heater, under the window, it's easier to put a desk there than, say, a dresser cabinet (even one that is short enough not to extend past the windowsill). Cabinets will have a small cutaway for baseboard trim; that's about it.

comment Why don't metals bond when touched together?
@deed02392 Note that large flat objects pressed together are also hard to separate simply due to atmospheric pressure. The space between them is a void, and air has to rush in when you separate them. Early in the separation, the crevice through which air can get in is small.

comment Why don't metals bond when touched together?
@jcw An electric current can break through the oxidation layers. This is called fritting. Though not an instance of welding, it explains why high voltage electrical contacts don't have to be maintained much. Even a pretty tarnished appliance plug, for instance, will work fine. But, say, small-signal connectors (e.g. audio) will not perform well if they are not clean and polished. (It's good for high voltage connectors to be in good condition too, so that fritting doesn't have to be relied on so much. A high initial contact resistance that has to be broken down could briefly generate heat.)
