"The multiplier effect is a major feature of networks and flows. It arises regardless of the particular nature of the resource, be it goods, money, or messages."

"nonlinear interactions almost always make the behavior of the aggregate more complicated than would be predicted by summing or averaging."

"If we are to understand the interactions of a large number of agents, we must first be able to describe the capabilities of individual agents."

"With theory, we can separate fundamental characteristics from fascinating idiosyncrasies and incidental features. Theory supplies landmarks and guideposts, and we begin to know what to observe and where to act."

"Even though these complex systems differ in detail, the question of coherence under change is the central enigma for each."

""Doing science," particularly the synthesis of disparate ideas, is not as arcane as it is often made out to be. Discipline and taste play a vital role, but the activity is familiar to anyone who has made some effort to be creative."

"I can't believe that a coloured girl from the back woods of Mississippi has done all that you have done"

"You are so special. I'm so proud of you."

"I love you for making the difference in my life."

"I teach identity leadership, based on the philosophy that you can’t lead anybody else until you lead yourself. Once you understand who you are, you can really focus on becoming the expert in your field."

"A photographer's best work is, alas, generally done for himself."

"Behaviorists tell us that we tend to overweight and overreact to the most recently received information. If we do, we will find that the information that we thought was so important becomes tempered, and reduced in significance, by new and related information that follows."

"Less volatile stocks tend to have negative abnormal profits; more volatile stocks tend to have positive abnormal profits."

"The cheapness family is the most powerful of the five."

"If we observe the performance of only those funds that remain active, we will tend to find that the average performance of the surviving funds exceeds that of the market."

"The cheaper the stock, the better the outlook for future returns."

"A comprehensive list of factors brings predictive stability and predictive stability and predictive power."

"So you see, in the end, it is nearly certain that the power of prediction must triumph over the arrogance of elegance."

"The New Finance focused on the market's major systematic mistake. In failing to appreciate the strength of competitive forces in a market economy, it over estimates the length of the short run. In doing so, it overreacts to records of success and failure for individual companies, driving the prices of successful firms too high and their unsuccessful counterparts too low."

"In going directly to Investment Heaven, you build your portfolio as you would build a wonderful company through a merger and acquisition program. You specify the way you want your portfolio to look, and then you assemble the profile piece by piece by bringing together companies that make their own individual contributions to the desired character."

"In real-world Finance, they don't pay for elegance. They pay for power - predictive power."

"CAPM also makes use of what is called a "definitional identity." This is something that is automatically true, simply because of the way things have been defined."

"When you buy a lottery ticket, you don't know how tickets have been sold. But sold they have been. And there is an underlying distribution for the game."

"Although efficient markets people still go around saying there is a "mountain" of evidence supporting their hypothesis, the truth of the matter is that it's a very old mountain that's now eroding rapidly into the sea."

"Entropy is not about speeds or positions of particles, the way temperature and pressure and volume are, but about our lack of information."

"If quantum communication and quantum computation are to flourish, a new information theory will have to be developed."

"As every bookie knows instinctively, a number such as reliability - a qualitative rather than a quantitative measure - is needed to make the valuation of information practically useful."

"Paradox is the sharpest scalpel in the satchel of science. Nothing concentrates the mind as effectively, regardless of whether it pits two competing theories against each other, or theory against observation, or a compelling mathematical deduction against ordinary common sense."

"This is not what I thought physics was about when I started out: I learned that the idea is to explain nature in terms of clearly understood mathematical laws; but perhaps comparisons are the best we can hope for."

"As with all quantum devices, a qubit is a delicate flower. If you so much as look at it, you destroy it."

"Nowhere is the difference between either/or and both/and more clearly apparent than in the context of information."

"An electron is real; a probability is not."

"The switch from 'steam engines' to 'heat engines' signals the transition from engineering practice to theoretical science."

"To put it one way, a collection of Shakespeare's plays is richer than a phone book that uses the same number of letters; to put it another, the essence of information lies in the relationships among bits, not their sheer number."

"Both induction and deduction, reasoning from the particular and the general, and back again from the universal to the specific, form the essence to scientific thinking."

"The problem of defining exactly what is meant by the signal velocity, which cropped up as long ago as 1907, has not been solved."

"Time has been called God's way of making sure that everything doesn't happen at once. In the same spirit, noise is Nature's way of making sure that we don't find out everything that happens. Noise, in short, is the protector of information."

"In fact, an information theory that leaves out the issue of noise turns out to have no content."

"The smell of subjectivity clings to the mechanical definition of complexity as stubbornly as it sticks to the definition of information."

"If the intensity of the material world is plotted along the horizontal axis, and the response of the human mind is on the vertical, the relation between the two is represented by the logarithmic curve. Could this rule provide a clue to the relationship between the objective measure of information, and our subjective perception of it?"

"The solution of the Monty Hall problem hinges on the concept of information, and more specifically, on the relationship between added information and probability."

"Underneath the shifting appearances of the world as perceived by our unreliable senses, is there, or is there not, a bedrock of objective reality?"

"If you don't understand something, break it apart; reduce it to its components. Since they are simpler than the whole,you have a much better chance of understanding them; and when you have succeeded in doing that, put the whole thing back together again."

"Numbers instill a feeling for the lie of the land, and furnish grist for the mathematical mill that is the physicist's principal tool."

"Science has taught us that what we see and touch is not what is really there."

"Claude Shannon, the founder of information theory, invented a way to measure 'the amount of information' in a message without defining the word 'information' itself, nor even addressing the question of the meaning of the message."

"In order to understand information, we must define it; bit in order to define it, we must first understand it. Where to start?"

"We don't know what energy is, any more than we know what information is, but as a now robust scientific concept we can describe it in precise mathematical terms, and as a commodity we can measure, market, regulate and tax it."

"Information gently but relentlessly drizzles down on us in an invisible, impalpable electric rain."

"He was an excellent disciplinarian, a splendid teacher, and a man looking for the good in everybody, which he invariably found and brought out. Great in his goodness of character and life, and of charming personality, he left a lasting impress on the annals of this institution."
