How does an induction cookstove work (Technical)

A small note on how an induction cooktop works. Picture is courtsey theinductionsite.com/how-induction-works.shtml
The electronics of the induction stove send an a/c to an electromagnet below the cooking vessel. The magnetic field generated by this electromagnet(1) passes through the bottom of the magnetic cooking vessel (2), producing an current flow in the metal of the vessel. The current flow through the resistance of the metal vessel generates the heat for cooking.

Its not fair (Social)

Ever wondered about the term "Its not fair"? A simple phrase, but very racist, since it says that "fair" or "white" is right, and "unfair" or brown/black is wrong. Probably your reaction is "Give me a break!". I wish I could be easy about this seemingly harmless comment. But I couldn't, hence this post! You may have heard comments such as "its mighty white of you to say that" or "its very Christian of you". Many of us would not use such comments, and would probably raise an eyebrow when we heard it. But maybe that's just because these comments are still new, while "its not fair" has been in use for a long time. In the beginning, maybe people raised an eyebrow, but then let it slide, and slowly it entered the normal conversation to such an extent that white, brown, asians and black freely use it now without a thought. It is possible that some years down the line the other comments find their way into everyday conversations as well. Personally, I don't use "its not fair" because "its not correct"!

Meat Industry (Social)

Welcome to my first blog. I recently came across this great website, www.meat.org. This website shows a video titled "meet your meat". And what a meeting! Although I knew that the animals are mistreated, for some reason I hadn't paid enough interest to the issue. I would urge you to check it out. It is relevant for vegetarians as well as non-vegetarians, as it talks about animals used for meat, milk and eggs. Please realize that everytime we make an unthinking decision by buying some random meat, milk and egg (that is without knowing where it came from) we are supporting and endorsing everything shown in this video. The guys that the video shows who throw the animals in the trucks, beat them with a stick, brand and castrate them in the brutal manner are NOT GUILTY. They are supposed to do their work fast, and hauling huge chickens is not so easy. It is us who are guilty, through and through.
Today I went to subway, and saw that everyone other than me ordered meat in their subs. I wanted to ask people to just eat meat twice or thrice a week, instead of everyday. Is that so difficult?
Our choice is to go local. We can get eggs and meat from the local farm, and milk also locally, and ensure that the cows that give the milk are free roaming. Meyer dairy in State College, for instance, told me that their milk is from free roaming cows, though of-course, the best solution is to drive to the farm to get the info first hand. Although this might sound tedious, it really isn't, since we only have to find out once if the farm is acceptable, and then can buy every time from the same farm.
I hope this video will affect everyone as it affects me, and move people to take action.
Thanks!
