Engineers Are Not Superhuman

2011-09-05T17:17:00.010+05:30

"Engineers are not superhuman. They make mistakes in their assumptions, in their calculations, in their conclusions. That they make mistakes is forgivable; that they catch them is imperative. Thus it is the essence of modern engineering not only to be able to check one's own work but also to have one's work checked and to be able to check the work of others." - Henry Petroski

The Profile of Industrial Designer

2011-09-04T22:57:00.004+05:30

"If the point of contact between the product and people becomes a point of friction, then the industrial designer has failed. On the other hand, if people are made safer, more efficient, more comfortable - or just plain happier - by contact with the product, then the designer has succeeded." - Henry Dreyfuss
