		<description>Karl,

It seems we&#039;re talking about different things. I am saying that there can be data less than one bit and you&#039;re saying (if I understand you correctly) that any data requires an integer number of bits to store/encode.

Case in point, Stark could have taken data requiring large storage space but containing little information.

Btw, I am not really an expert (or even formally trained) in Information Theory, just interested in it.

Also, technically, petabytes of data IS &quot;picobytes&quot; of data, only a very large number of picobytes.</description>

		<description>Rono, you are talking about information &quot;value&quot; in regards to information utility, not data size.  

&quot;Using this logic, knowing whether a card is a spade and knowing if it is the jack of spades have the same information value.&quot;

No, that only sort of follows if you have two registers to populate, one that always represents &quot;spadeness&quot; and one that always represents &quot;Jack of Spadeness&quot; to assign 0 or 1 values, but then you&#039;d be using two different encoding schemes.

But you missed the point, both of thoses peices of data require a minimum of one bit of data to encode, even if you use a special, unique coding scheme for each.

Please provide an example of how you would encode any piece of data in less than one bit.

I think you&#039;re equating information theory with data storage/coding, and while they closely related, they&#039;re not the same thing.

Information theory might say that if I send you 10MB of data, and you already had 9MB of it, that I only transmited 1MB of inforamtion to you, but I did transmit 10MB (gross) of data to you, and you didn&#039;t know that you only got 1MB (net) of new information until you compared what you recieved to what you already had.</description>

		<description>Karl:

&quot;...since the event either happened or it didn’t happen, knowing whether it happened or not represents one (whole) discrete bit of data, with a binary value equal to either 0 or 1 (0= it didn’t happen, 1= it did), independent of the weight or utility of that information...&quot;

Using this logic, knowing whether a card is a spade and knowing if it is the jack of spades have the same information value.

I like to think of it this way. If you&#039;re playing 20 questions, the best questions (questions that have answers with most information value) are those which about halve the possibilities.</description>

		<description>You have a problem with your MOST recent post..here&#039;s what you typed for Spiderman 600

When evaluating the papillary response in a patient, have them


You should have typed pupillary  cmon Doc, haha...Great site.</description>

		<description>well as for #1:  The girls are wearing sunglasses at night so perhaps they&#039;re simply ultra-sensitive to light...though why you would still check for papillary response I don&#039;t know.

As for #2.  Perhaps Osborne knows the info he&#039;s giving is B.S, and so he&#039;s trying to bluff them.  And it is the Green Goblin after all so rather than make the request plausible, he&#039;s trying to confuse them with total technobabble.</description>

		<description>Regarding the size of a byte from Wikipedia:

&quot;A byte (pronounced /ˈbaɪt/) is a unit of information storage representing the smallest addressable element for a given computer architecture. It often designates a sequence of bits (binary digits) whose length is determined by the architecture. However, the use of a byte to mean eight bits has become ubiquitous.&quot;

-So originally a byte was the basic unit of data of a given computer architecture, but because the most common early computers were 8 bit computers with 8 bit bytes, common usage refined the byte as 8 bits.  All hail the Apple II and its 8 bit MosTek R6502 CPU!</description>

		<description>&lt;font color=&quot;green&quot;&gt;Historically, there have been systems that used non-8-bit bytes, before the 8-bit became standard.  For instance, UNIVAC 1100/2200 used 6- and 9-bit bytes and the IBM 360 and PDP-10 also used non-8-bit bytes.

Then there&#039;s C++ (from the &lt;a href=&quot;http://www.parashift.com/c++-faq-lite/intrinsic-types.html#faq-26.4&quot; rel=&quot;nofollow&quot;&gt;C/C++ FAQ Lite&lt;/a&gt;)

&lt;blockquote&gt;[26.4] But, but, but what about machines where a char has more than 8 bits? Surely you&#039;re not saying a C++ byte might have more than 8 bits, are you?!?

Yep, that&#039;s right: a C++ byte might have more than 8 bits.

The C++ language guarantees a byte must always have at least 8 bits. But there are implementations of C++ that have more than 8 bits per byte. &lt;/blockquote&gt;&lt;/font&gt;</description>
