Sage helps in a wide range of mathematics
Do certain math problems have you stumped? Perhaps you need help with computations in CAD-based models. Whatever the problem may be, Sage has you covered. The software was created using almost 100 open-source packages that are unified under one interface for ease of use. The platform can be used for a myriad of mathematical applications, including calculus, algebra and elementary math. There is also advanced 'Doc Brown' applications incorporated as well, such as group theory, cryptography and combinatorics among a host of others. The downloadable software is accessed through a web browser and connects locally to either your Sage installation or through Sage's network server. The interface is quite interesting and is in 'notebook' form, which allows users to create customized graphics, mathematical expressions (for the String Theory fans) and add/delete input based on specific projects. Moreover, you can create incredible 'Spirograph' artworks just like using the retro toy from your childhood.

More information:  Sage.

In the article number 7. The author wrote this app is free but it is not.

For viewing Gerber files I recommend GC-Prevue from www.graphicode.com.  It is a free Gerber file viewer.  They also have other more-capable purchasable tools.

Add QUCS to the Free Design Tools

Quite Universal Circuit Simulator (QUCS) is a great little Spice-like open-source tool that runs quickly, has a wide range of components, rather intuitie interface (but a so-so manual), and will execute S-parameter analysis. Available at qucs.sourceforge.net/.

I've used Eureqa by www.nutonian.com, sounds similar.  There's a useful but limited free version.

I have tried FreePCB couple of times, it is not bad for most projects with 16 layers or less. Some features I wish it had are viewing Gerber files, import/export of DXF files and print capability!

What is the basis of this ranking?

Is this ranking based on a survey of engineers? If so, what is the size of the sample and how was the sample chosen?

:-)  Yes, it can be a rare commodity when engineers interact with non-engineers!  Oh, well, c'est la vie!

I cannot disagree.  I suppose I've been lucky a lot of the time; I usually have the opportunity to insist that things are done properly.  I don't take that for granted. ;)

Not disputing that.  But time is a constraint that must also be accommodated...and meeting the schedule is not always "not good engineering." 

 

I think we have to meet in the middle here.
