Sabrina Lloyd's Quotes

In this metaphor we actually have a picture of the computational universe, a metaphor which I hope to make scientifically precise as part of a research program.

Indeed, as the above calculation indicates, to take full advantage of the memory space available, the ultimate laptop must turn all its matter into energy.

Instead of having to be a member of the Royal Society to do science, the way you had to be in England in the 17th, 18th, centuries today pretty much anybody who wants to do it can, and the information that they need to do it is there.

It's also a reasonable scientific program to look at the dynamics of the standard model and to try to prove from that dynamics that it is computationally capable.

Merely by existing and evolving in time - by existing - any physical system registers information, and by evolving in time it transforms or processes that information.

Of course, not everybody's willing to go out and do the experiments, but for the people who are willing to go out and do that, - if the experiments don't work, then it means it's not science.

Of course, one way of thinking about all of life and civilization is as being about how the world registers and processes information. Certainly that's what sex is about; that's what history is about.

One of the things that I've been doing recently in my scientific research is to ask this question: Is the universe actually capable of performing things like digital computations?

The amount of information that can be stored by the ultimate laptop, 10 to the 31st bits, is much higher than the 10 to the 10th bits stored on current laptops.

It's important to understand how people perceive risk, and how that translates into investment behavior.

Most people are overconfident about their own abilities. That is probably a good thing. But we would be horrified if a physician's aide engaged in heart surgery.

Ideas percolate. Through natural selection, the best ones survive.

If we are able to allow people to earn a decent rate of return, with sufficient scale, we can all do well by doing good.

Maybe we should teach schoolchildren probability theory and investment risk management.

My mother died of lung cancer last year. I felt helpless. As an economist, I thought, 'What can I do?'

While neurological studies have tried to identify components responsible for fear and greed, the impact on finance is less clear.

During periods of extreme fear or greed, you don't have the proper balance between those two to generate market efficiency and you get extremes in behavior.

If troubled companies want to explain away 2008 as a 'black swan,' then someone should take responsibility for creating the oil slick that seems to have tarred the entire flock!

If you rank the top 50 one-day moves in the S&P 500, a fair number of those happened within the last five or 10 years. That tells you that we're in a different, riskier market now.

Many of us like to think of financial economics as a science, but complex events like the financial crisis suggest that this conceit may be more wishful thinking than reality.

More and more investors may be coming into markets everywhere but that doesn't mean that the markets are really getting more and more efficient, even in the United States. It does mean that there is more access for savvy investors who watch the money flows.

Some people might say, 'Can we afford it?' I think that's asking the wrong question... We should instead be asking, 'Can we really afford not to try?'

The adaptive markets hypothesis says that all economic institutions, like our own species, develop and change over time, depending on the population of investors that are engaged with them.

The United States has the most sophisticated financial markets in the world, which does not leave much room to maneuver. But it also offers investors the greatest access to information and the ability to execute trades quickly and efficiently. So it is a mixed bag of opportunity.

What makes this story so remarkable is that throughout my early childhood I had ongoing learning difficulties, particularly in mathematics. I struggled to learn the multiplication table, and no matter how hard I tried, I simply couldn't remember 6 times 7 or 7 times 8.
