Just as a side dish, without talking to the source (Mr. Peter Hackman) itself, I have chosen to translate a few laws, principles, lemma, theorem, lemmas, or what have you, what ever lingua mathematicians use.

Mr. Peter Hackman was with the Mathematics department at Linköping University – from the origins (yes, we’re not that old) – more or less – until his retirement in 2006. He was famous for the books in various types of algebra, for example the “Book with the cow on”. I had the pleasure to have Mr. Hackman in two courses, Linear Algebra and Linear Algebra, second course. One could argue what use I have had of that knowledge in my current life as an electronics engineer, but nevertheless, the maths is quite fun and nice to work with. In-between, the rotation of the parrot was, and this needs confirmation, done by a fellow Ölänning of mine.

Anyhow, Mr. Hackman, had quite a set of different opinions and on his home page he has published a few ideas on “pedagoja”, a combination of the words pedagogics and “goja”, where the latter implies talking jibberisch. (The latter could also refer to parrot in slang-Swedish.) So, the laws, lemmas, theorem, what have you, are the following (and I am taking them from the source directly and try to translate to the best of my knowledge):

- “Hackmans Enkelhetsprincip”, “Krångla inte till saker i onödan”.

**Hackman’s principle of simplicity.***Don’t make things too complicated if you do not have to.* - “Hackmans Nyttoprincip”. “Gör inte en massa dumheter i onödan”

**Hackman’s principle of utility.***Don’t do a lot of silly things if you do not have to.* - “Hackmans Kausalitetsprincip”. “Det är så för det blir så”.

**Hackman’s principle of causality.***It is that way, since it is that way.*or [edit, kiitos Janne]*That is a fact because the result will be so.* - “Hackmans Osäkerhetsprincip”. “Goda föreläsningar drivs av osäkerheten om deras slutliga innehåll”.

**Hackman’s principle of uncertainty.***Good lectures are driven by the uncertainty about their final contents.* - “Hackmans Paradox”. “Läroböcker ska vara kompletta, föreläsaren ska komplettera dem.”

**Hackman’s paradox.***Course literature should be complete. The lecturer should complement them.* - “Hackmans genusprincip”. “Även kvinnor tjänar på att behandlas som individer”.

**Hackman’s principle of gender.***Women too benefit from being treated as individuals.* - “Hackmans omvända kvadratlag”. “Professorers intellektuella briljans avtar med kvadraten på avståndet till den egna specialiteten”.

**Hackman’s inverse square law.**[Edit, thanks Mikael].*The intellectual brilliance of professors is inversely proportional to the square of the distance from their own field of expertise.*

All of these would apply to most fields of education and research. And I must say I support most of them. I guess it is worth with a follow-up post on this…

And once again, the disclaimer here is that this is work by Mr. Hackman, the quotes are from his public homepage, and I just replicate them with a translation into English. And I know that some of it is lost in translation and I might need some assistance to finalize them…

The message from #3 should be something like “That is a fact because the result will be so.”, but it’s not easy to translate.

Ah, thanks – adding that to the list 🙂

I would translate #7 as: The intellectual brilliance of Professors is inversely proportional to the square of the distance from their own field of expertise.

Perfect! Thanks, adding that too.
