There were two motivations why I wrote this article: - Recently I have undertaken coaching mathematics, physics and computer science. - I saw an interesting video1 from the mistakes of mathematics education, and the lecturer outlined a better teaching method.   In this way I have recurrently getting a lot of experience about how bad methodology is used in mathematics education not only here in Hungary, but everywhere in the world. But let us take some examples from my own experience: ... 

To George Steiner with love The title is a bit misleading because I do not want to write about people but about an essay written George Steiner. I would like to answer to the problem of the cacophony of languages. George Steiner wrote about this problem a lot, for example in his essay titled "The talking animals", and it is also raised in his book titled "After Babel". The diversity of languages and thus the need of the process of translation are obstacles to human development, according to George Steiner. With these thoughts I want to argue, more precisely I would like to add a reassuring answer to what the writer says: “... ... Any information theory, or a single model…

Thoughts about a radio show A few weeks ago, an interesting radio program was aired in the Space-time series: "From the stone tablet to the printer. Thoughts about writing". I also brooded on speech and writing and some claims of the program kindled my imagination. The spoken and written word can be characterized in many ways: - Because of its fixation, writing is dead but live speech is dead as well if it has already been spoken.- Listening to spoken language and reading always means translating: the speech model of the author's thoughts have to be transformed into thoughts of the listener or thoughts of the reader. - When reading a written text, there is no online real-time metacommunicational contact…

I thought that as soon as I should become my own master I would immediately enter into public life. But it so happened, I found, that the following changes occurred in the political situation. In the government then existing, reviled as it was by many, a revolution took place; and the revolution was headed by fifty-one leaders… Now of these some were actually connections and acquaintances of mine; and indeed they invited me at once to join their administration, thinking it would be congenial. The feelings…

One of my friends drew my attention to an article on a web page on information protection. The article deals with the Fifth Amendment to the United States Constitution1 and its use. I do not wish to discuss the given case now or outline encryption-related problems. I focus on a much more general problem instead; the fight of information security efforts and efforts in the disclosure of information. I worked in the field of informatics for nearly twenty years at big companies incl. multinational companies, initially as an IT auditor, and then as an IT security officer. Beside that, information theory became my favourite field of interest. The practice of the process of information and theoretical considerations shaped my opinion…
