A Quote by Herbert Simon

The aim ... is to provide a clear and rigorous basis for determining when a causal ordering can be said to hold between two variables or groups of variables in a model . . . . The concepts refer to a model-a system of equations-and not to the 'real' world the model purports to describe.

When evaluating a model, at least two broad standards are relevant. One is whether the model is consistent with the data. The other is whether the model is consistent with the 'real world.'

Kenneth A. Bollen

Considering the inconceivable complexity of processes even in a simple cell, it is little short of a miracle that the simplest possible model - namely, a linear equation between two variables - actually applies in quite a general number of cases.

Ludwig von Bertalanffy

There was a 3-foot-long model that was built for 'New Hope,' and then there was an 8-foot model that was built for 'Empire Strikes Back.' The 8-foot model and the 3-foot model are kind of different. A lot of the details are different between the two of them.

John Knoll

A model is a good model if first it interprets a wide range of observations in terms of a simple and elegant model, and second if the model makes definite predictions that can be tested, and possibly falsified, by observation.

Stephen Hawking

The power of equations lies in the philosophically difficult correspondence between mathematics, a collective creation of human minds, and an external physical reality. Equations model deep patterns in the outside world. By learning to value equations, and to read the stories they tell, we can uncover vital features of the world around us.

Ian Stewart

The image of the world around us, which we carry in our head, is just a model. Nobody in his head imagines all the world, government or country. He has only selected concepts, and relationships between them, and uses those to represent the real system.

Jay Wright Forrester

At that point it certainly would be called abstract. That is to say, you had a model and there'd be one or two or three people there drawing the model but otherwise you had abstractions all around the room, even though the model was in front of you.

Lee Krasner

The capitalist model, the developed model, the consumer model which comes from the North, which it has forced on the world, is falling apart on Earth, and there is no planet nearby that we can emigrate to.

Hugo Chavez

I did model for a little while part-time, but I wasn't a bloody model, and I am definitely not that horrible thing 'model-turned-actress.'

Tamsin Egerton

For the third generation Unreal Engine, we are building two versions of every model in our game. We are building a source model with several million polygons, between 2 and 6 million polygons. We use that model for all the lighting detail on the mesh. Then we go to the in-game version, which is usually about 10,000 polygons.

Tim Sweeney

I was never a model-y model. I was doing it as a job, but people didn't even know I was a model.

Olga Kurylenko

I think the free market model of commercial trade openness - this model has undoubtedly shown enormous benefits for nations, for those of us that follow this model, of course.

Enrique Pena Nieto

The model a lot of companies use is a very pyramidal model which sort of designates that all creativity, all wisdom flows from the top. We think that's the absolute wrong model.

Richard Hayne

there are only two basic ways of structuring the relations between the female and male halves of humanity. All societies are patterned on either a dominator model - in which human hierarchies are ultimately backed up by force or the threat of force - or a partnership model, with variations in between.

Riane Eisler

I didn't have a role model. My role model was Michael Jordan. Bad role model for an Indian dude... I didn't have anyone who looked like me. And by the time I was old enough to have what could have been a role model, they were my peers. Aziz Ansari is my peer. Kal Penn is my peer.

Utkarsh Ambudkar

Your perception of the world is ... really a fabrication of your model of the world. You don't really see light or sound. You perceive it because your model says this is how the world is, and those patterns invoke the model. It's hard to believe, but it really is true.

Jeff Hawkins
