{ s(Q|X) = -K SUM(p*ln(p)) }: "Symbols, Signals and Noise" by J. R. Pierce
An Introduction to Information Theory: Symbols, Signals and Noise - John Robinson Pierce



(Original Review, 1980-12-05)



Final answer to question, "How many joules to send a bit?"

The unit of information is determined by the choice of the arbitrary scale factor K in Shannon's entropy formula:

{ s(Q|X) = -K SUM(p*ln(p)) }

If K is made equal to 1/ln(2), then S is said to be measured in "bits" of information.

Reading progress update: I've listened 583 out of 4260 minutes.
Sherlock Holmes: The Definitive Collection - Arthur Conan Doyle,Stephen Fry

"I fear that it may be the last investigation in which I shall have the chance of studying your methods. Miss Morstan has done me the honour to accept me as a husband in prospective."
He gave a most dismal groan.
"I feared as much," said he. "I really cannot congratulate you."
I was a little hurt.
"Have you any reason to be dissatisfied with my choice?" I asked.
"Not at all. I think she is one of the most charming young ladies I ever met and might have been most useful in such work as we have been doing. She had a decided genius that way witness the way in which she preserved that Agra plan from all the other papers of her father. But love is an emotional thing, and whatever is emotional is opposed to that true cold reason which I place above all things. I should never marry myself, lest I bias my judgment."

 

There is so much to unpack there. Holmes regard, then the stab at love, and his stance on marriage, half sad, and also, half romantic, because not said there is that for him, marriage is for love *grin*

 

"The division seems rather unfair," I remarked. "You have done all the work in this business. I get a wife out of it, Jones gets the credit, pray what remains for you?"
"For me," said Sherlock Holmes, "there still remains the cocaine-bottle."

 

I will forever wince at those last lines. I'm aware that in context, the opium and cocaine thing is akin to chain smoking and monster espressos/energy drinks, so it's not exactly the jolt of time marching on, but this full circle we make with the beginning. He lives for the mystery and is truly alive during the case. It's brilliant to see, but sad, and lonely.

 

Also, I've seen a lot around about Holmes being a depiction of a manic-depressive, but I wonder. He's very trigger-orientated on his phases.

 

Onto the short stories now

Two things:

 

"Go on, you drunken vagabond," said the face. "If you kick up any more row, I'll open the kennels and let out forty-three dogs upon you."
"If you'll let one out, it's just what I have come for," said I.

 

I love sassy Watson. I think people forget that part about him, much like his intelligence, or maybe just plain ignore, given the usual portrayals on more contemporary media, and the contrast with the mysterious genius that is Holmes mind.

 

Also, I keep laughing at this repeat of Holmes' name opening doors. Lots of friends and respect from strange quarters.

Coming around the middle of The Sign of Four, there is this bit

 

So swift, silent, and furtive were his movements, like those of a trained bloodhound picking out a scent, that I could not but think what a terrible criminal he would have made had he turned his energy and sagacity against the law instead of exerting them in its defence.

 

I think even Doyle himself got interested, and the need to explore such a character seeded.
