Balloons and Static Electricity – UCSB Physics Circus
When water comes out of the faucet it is neutral, meaning that it has positive and negative charges in it. However, when we bring the balloon close to the water, some of the negative charge is repelled away into other parts of the water (the top and bottom of the stream), leaving the middle of the stream of water (by the balloon) …

The me and the not-me: Positive and negative poles of identity.
The author suggests, in the future, that identity theory and research take account of the negative pole of identity, the Not-Me self-disidentification, in addition to its more familiar positive pole, the Me. But, in doing so, not be confined to situation-scale timespans, for the self is an enduring, fairly stable system. The self as object--the Me, but also the Not-Me- …
Magnetism – The Wonders of Physics – UW–Madison
Magnets are objects, which can attract, or pull, on some metals, like iron and steel. If you rub a piece of steel with a strong magnet, the piece of steel will become a magnet too. It has become magnetized. Other metals, like copper or gold, are not attracted to magnets. Magnets can also attract each…
The Positive and Negative Side of Lightning
Positive lightning strike, copyright by Radek Dolecki - Electric Skies.Download Image The previous section describes what is called "negative lightning" because it is the transfer of negative charge from the cloud to the ground. However, not all lightning forms in the negatively charged region under t
