comment Why are downed power lines dangerous?
A grid isn't the same as a net, you ultimatley only have one cable to a customer. If a larger powerline goes down the last point you can switch it may also connect to other lines - the problem is that high power remote switches are big, expensive and create reliability problems themselves, so you have them on a large scale and then manually operated pole/transformer switches on a smaller scale that you have to send a crew to

comment Why are downed power lines dangerous?
@Mason when a line breaks you can kill the power when you detect that you have a break. The problem is that the nearest place you can disconnect the power may not be just the broken section. It's better to leave a broken live line fenced off than turn off power to a dozen city blocks containing a hospital or fire station

comment Is there a reason for photodynamic therapy to not cause cancer if mobile phones might?
@Alex - sorry not a very good analogy. More like a bullet is made of metal and is dangerous therefore a buick made of metal is also dangerous. I added a better explanation

comment Is anything actually 1 meter long (or 1kg of weight)?
@The Chaz, The meter is now defined in terms of the distance light goes in a certain fraction of a second. As measurements of the speed of light improve we change the definition of the metre since it is much more convenient to have a fixed second and a fixed speed of light. So the metre isn't really fixed anymore
