While I'm waiting for my photos to upload, very slow today, hope they don't timeout on me, I shall research on stuff that have been fluttering in my mind this holidays.
White Chocolate
White chocolate is a type of chocolate based on cocoa butter without the cocoa solids. It also includes milk solids, sugar, lecithin, and flavorings (usually including vanilla). Cocoa butter is the ingredient used in other chocolates so that they remain solid at room temperature yet melt easily in the mouth. Thus, white chocolate has a texture like that of chocolate but does not have the same taste. Unlike chocolate it does not contain caffeine. As white chocolate does not contain cocoa solids or cocoa mass, it does not meet the standards to be called chocolate in many countries. In the United States, since 2004, white chocolate needs to be at least 20% (by weight) cocoa butter, at least 14% total milk solids, and less than 55% sweeteners such as sugar.

Piano roll
A piano roll is a roll of paper with perforations (holes) punched in it. The position and length of the perforation determines the note played on the piano. The piano roll moves over a device known as the 'tracker bar', which first had 58 holes, was expanded to 65 and then was upgraded to 88 holes (generally, one for each piano key). When a perforation passes over the hole, the note sounds.
That's how the piano can play by itself and how the earliest recordings were made. What I don't get is how the holes can transmit information, is there a stream of air that blows through the paper? Light sensor? Electric sensing? Anyone care to enlighten me?
Scientology
The Church says that Scientology is concerned with "the study and handling of the spirit in relationship to itself, others and all of life." Dianetics is more narrowly focused on getting rid of the reactive mind, the "bank" of traumatic memories known as engrams which are said to inhibit one's success and happiness. Basically it's to reach into the good and logical part of the soul and use that to achieve goals in life. They do this by talking to each other and solving each other's problems. We visited this Church of Scientology in SF and listened to this sweet old lady tell us all about scientology. According to her, scientology is an open-minded religion where you choose to believe in anything you believe, scientology just helps you achieve your goals. We concluded that scientology is a huge self-help group. Wiki seems to think otherwise though, talking about mind control and disconnection from people who are in objection to scientology. Reading Wiki, scientology sounds like a computer game where you have to advance through the levels to uncover more secrets of the world. And somewhere in it all, there's an alien manipulating everything. Fun.
