 Students Reliant on Computer Simulations Lack the Technic...

In the 1980s, alternate visions of computers and the future of design were expressed in competing views about programming. Some architects believed that designers needed to learn advanced programming. If designers did not understand how their tools were constructed, they would not only be dependent on computer experts but less likely to challenge screen realities. Other architects disagreed. They argued that, in the future, creativity would not depend on understanding one’s tools but on usi...

 Top-Down VS Bottom-Up Approaches to Design in Software

One of the hallmarks of the Athena project was that faculty were asked to build their own educational software. Most worked with a set of assumptions about learning: students begin by learning “fundamental concepts”; formal, mathematical representation is always the best approach; students would use simulations the way designers intended. As Athena unfolded, none of these assumptions proved true. To begin with, students approached simulation with a wide range of personal intellectual styl...

 The Danger of Black-Box Abstraction

When I was a graduate student, if you were going to convert some data or something like that, you would write the FORTRAN code to convert the data yourself. That’s how you would do it. Now there are these programs. There are these windows and you click. I .nd with my students all the time, they don’t know why something isn’t working. I’m like, well, did the data convert properly? Open the .le and look at it. It is so black box and it is going from the time when you knew how the data w...

 Where's Transparency With So Many Layers of Abstraction?

Some older scientists, for example, justify their use of opaque software by pointing to the infinite regress of computer representations. After all, they argue, it doesn’t really mean much to know how your simulation is programmed if all you are looking at is a high- level computer language. The “real guts” of the program is in assembly language and in all that lies beneath that, and no one wants to go to that level with today’s complex machines. In the 1980s, Professor Barry Nilo= in...

 Loss of Legacy Programmers Means Loss of Systems Understa...

At Livermore, a legendary senior weapons designer is about to retire. At the Spring 2005 MIT workshop, his colleagues discuss this retirement and refer to it as “a blow.” They are anxious about more than the loss of one man’s ability to make individual scientific contributions. He has irreplaceable knowledge about the programming that supports current practice.10 His colleagues fret: “He has such a great memory that he hasn’t written down lots of important stuff. How will people kno...

The newer users only know the interface, the abstraction, they don't know the code beneath it.

 Don't Let the Simulation's Beauty Convince You It's Real

The architecture faculty who designed Project Athena’s Garden dreamed of transparent understanding of design process; today scientists are reconciled to opacity and seeing only a CAVE’s shadows. Over the past twenty years, simulation has introduced its dazzling environments and we have been witness to our own seduction. A mechanical engineer instructs his students: “Don’t be fooled by the graphics.”17 Luft says that beautiful codes promote the “illusion of doing really great scien...

 Computing is Pop Culture without History

Binstock: You seem fastidious about always giving people credit for their work. Kay: Well, I'm an old-fashioned guy. And I also happen to believe in history. The lack of interest, the disdain for history is what makes computing not-quite-a-field. Binstock: You once referred to computing as pop culture. Kay: It is. Complete pop culture. I'm not against pop culture. Developed music, for instance, needs a pop culture. There's a tendency to over-develop. Brahms and Dvorak needed gypsy music ba...

 A Quantum Game

Bell came up with “nonlocal” games, which require players to be at a distance from each other with no way to communicate. Each player answers a question. The players win or lose based on the compatibility of their answers. One such game is the magic square game. There are two players, Alice and Bob, each with a 3-by-3 grid. A referee tells Alice to fill out one particular row in the grid — say the second row — by putting either a 1 or a 0 in each box, such that the sum of the number...

 Asimov Story on Computation

■ N 1958, American science fiction legend Isaac Asimov wrote a very short story called "The Feeling of Power." In it, lowly technician MyI ron Aub discovers that he is capable of duplicating the work of his computer by multiplying two numbers together on a piece of paper. Amazing! This miraculous discovery makes its way up the chain of command, where the generals and politicians are stunned by Aub's black magic. The top general is intrigued by the possibility that human calculations could g...
