Vat Number On Quotes

In 1999 the RAND Corporation published a report (the first and, so far, last of its kind) with a “conservative estimate” that more than 307 million tissue samples from more than 178 million people were stored in the United States alone. This number, the report said, was increasing by more than 20 million samples each year. The samples come from routine medical procedures, tests, operations, clinical trials, and research donations. They sit in lab freezers, on shelves, or in industrial vats of liquid nitrogen. They’re stored at military facilities, the FBI, and the National Institutes of Health.

I've focused on the 1,000 coins so as to offer a specific example, but the link between entropy and information is general. The microscopic details of any system contain information that's hidden when we take account of only macroscopic, overall features. For instance, you know the temperature, pressure, and volume of a vat of steam, but did an H2O molecule just hit the upper right-hand corner of the box? Did another just hit the mid-point of the lower left edge? As with the dropped dollars, a system's entropy is the number of yes-no questions that its microscopic details have the capacity to answer, and so the entropy is a measure of the system's hidden information content.

The authorities do try to minimise the number of deaths: guides are given some training in what to do if one of their group is showing signs of acute mountain sickness (AMS) and trekkers are required to register each night upon arrival at the campsite and have to pay a US$20 (plus VAT) ‘rescue fee’ as part of their park fees (though what this actually gets you is unclear). But you, too, can do your bit by avoiding AMS in the first place. The following pages discuss in detail what AMS actually is, how it is caused, the symptoms and, finally, how to avoid it.
