This is the amazing thing about Sage and an attribute of good software: you don't need to understand every detail in order to use it productively. And it motivates you to learn more and explore unknown fields such as mathematics. :) I just spoke to a Geography professor who said that it would be

I don't get it... how should this make SAGE easier? From my point of view, I don't even remember anymore (my bad I know) what a ring represent, but this is not slowing down my SAGE learning, I think. But what if tomorrow or the day after, I do need those? I'm sorry, I just don't get the point o

I think that you probably miss the point. Most engineers are not trained in number theory, group theory, advanced algebra, etc. Leaving these parts out of Sage would potentially make it easier to use. But then maybe the engineer should use Maxima, or one of those other systems that either ignore

I am an example for someone that does use both modes. I do symbolic derivations and transformations and then apply them to data, so I fancy a system where both symbolic evaluations and numerical approximations can be done transparently. If one is only interested in numerical evaluations, why n

You all make good points. Certainly more documentation for applied stuff is called for, and I really like the idea of a configuration command to avert having to maintain a separate version. Didn't even think of that! As regards size, I do think that it would be an important factor. I am much mor

Thank you all for your feedback. I agree that maintaining anoher version of Sage is probably spreading current resources too thin. I was asking to see if this was indeed the case. On the other hand, an engineering and physics oriented Sage could help boost Sage and bring in more resources from a
