As in other fields of Engineering, simulators are widely used to teach Memory hierarchy topics. In this paper, a simulator called MNEME (due to the muse of the memory in Greek mythology), which includes a complete vision of memory hierarchy topics, is presented. This simulator has been validated and improved using feedback from students during two academic years. This way, the students have taken part significantly in the MNEME design process.

Professor Chomsky, it is a great honor to talk to you; thank you for your precious time.It would be almost impossible to reduce all your work to one field or theme, and this is why I will try to touch on a few themes from the whole array of contributions you have made to science and human knowledge and spirit.You epitomized for years the freedom of expression for academics, media and the general public. How do you feel having such a distinctive tone in voicing the unspoken words of billions of people? Does it come as a great responsibility or as an exceptional emotionally charged challenge?Noam Chomsky: To the extent that the tone is "distinctive," that is a failure of the intellectual community, those who enjoy privilege and have the opportunity to defend such elementary values as freedom of expression, and much else, if they choose.Beatrice Popescu: As we all know, you are constantly deluged with interview requests from the media, especially on the latest international political issues, so dramatic that cannot suffer any delay. What convinced you to offer us an interview?Noam Chomsky: I do as much as I can, a fraction of what I would like. This seemed to me an unusual and attractive opportunity to engage in discussion with people with common interests whom I would very much like to meet in person, if I were able to arrange a visit to a part of the world where I have almost never been.Beatrice Popescu: We would be happy to invite you to Bucharest. Starting with psycholinguistics, I have noticed that a huge majority of academics never change their mind about anything, locking into a rigid position earlier in their careers, which they defend to the end of time. You, Professor, in contrast, have never stopped critiquing your own theories with the same energy with which you have criticized those of others (Skinner or Shannon). For almost half a century, your search for linguistic truth has been uncompromising. Looking at your prodigious career in psycholinguistics and especially at the newest perspective on "generative grammar", the Minimalist program, are there still any fundamental questions you did not consider in your research, are there any topics left out from the vigilant eye of the researcher?
