Simple Motor

I have been trying to start doing projects with the kids each weekend. Last weekend we tried to make a simple speaker from scratch, no success on that one so far. So this weekend I went for something easier and we made a simple motor out of wire, paperclips, magnets, tape, an AA bettery and two alligator clips. All taped to a plastic plate base. Above is a picture of it unhooked (I used small ceramic magnets to hold the wires to the battery). The coil is about 35 wraps of 26 AWG enamel coated wire. The connections to the clips have the enamel scraped off one side, so each revolution the electromagnet turns on and off repelling it from the magnets below and it spins. Below is a picture in action.

T made a motor like this from a kit a few years ago, but this one is completely from common off the shelf parts.

Palestine

Why shouldn't Palestine be able to participate internationally at the UN (i.e. receive UN recognition). Israel is a UN member. Palestinians are not Israeli citizens. Palestine is a separate nation. Palestinians and Israelis are both human beings. Is there any reasonable argument that Palestinians should not have any self determination. Is there any reasonable argument that Palestinians should not have the same level of recognition as everyone else?

"When in the Course of human events it becomes necessary for one people to dissolve the political bands which have connected them with another and to assume among the powers of the earth, the separate and equal station to which the Laws of Nature and of Nature's God entitle them, a decent respect to the opinions of mankind requires that they should declare the causes which impel them to the separation. We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty and the pursuit of Happiness. — That to secure these rights, Governments are instituted among Men, deriving their just powers from the consent of the governed, — That whenever any Form of Government becomes destructive of these ends, it is the Right of the People to alter or to abolish it, and to institute new Government, laying its foundation on such principles and organizing its powers in such form, as to them shall seem most likely to effect their Safety and Happiness. Prudence, indeed, will dictate that Governments long established should not be changed for light and transient causes; and accordingly all experience hath shewn that mankind are more disposed to suffer, while evils are sufferable than to right themselves by abolishing the forms to which they are accustomed. But when a long train of abuses and usurpations, pursuing invariably the same Object evinces a design to reduce them under absolute Despotism, it is their right, it is their duty, to throw off such Government, and to provide new Guards for their future security."

The family is here!

I have moved yet again, to a rental house. Also, V, T, M and the baby F arrived and I picked them up from the airport. We also just got internet access hooked up at home yesterday.
