Cosmic Calculations by Rosa Maria Ros

Cosmic Calculations by Rosa Maria Ros is book #30 in Our Mathematical World series by National Geographic. The first books seemed interesting, but not all in the series are equally interesting and there are 60 in total. But, this one was very nice.

Cosmic Calculations by Rosa Maria Ros

I’ve enjoyed it because it offers some lovely stories and, even more interesting, some experiments to make at home. Of course, the experiments are for teens, and so I will not try them at home, but it was nice to read about them in the book nevertheless. Reading this book made me want to pick up another one from this series and I will, as soon as I finish three books I plan to read before that (excluding ones for university).

I think this book was published in English only for the National Geographic series, so it’s not widely available. It you find another book by Rosa Maria Ros and you are interested in math related subjects, go for it, her style is great, not boring at all.

Also, you can learn about Milkomeda and read funny stories about sundials.

  • Hi Anca,

    I’m with Kelly, in that maths (we always add the ‘s’ in England) was not my favourite subject at school and I learnt (well I was taught) a whole bunch of things that I have never had recourse to use since my exams!

    National Geographic is an amazing organisation and their products are always quality publications, full of information which can be as technical or hobbyist as you want it to be. They did bring out a range of magazines specifically aimed at kids and they look awesome.

    We have a Bulgarian family living a couple of doors away from us and they speak only English when they are out in the community during the day and only Bulgarian when they are inside the family home. Their 10-year-old daughter has become completely bi-lingual in just a couple of years. Me, I have trouble remembering my school day French!

    Thanks for sharing, you read an amazingly eclectic mix of books 🙂

  • Even though I’m not a “math person”, I think this sounds interesting. National Geographic usually puts out quality things. I’ve read the magazine for years.

    Just out of curiosity, do you read everything in English or do you read some books/newspapers in Romanian? I know you’ve said Festus only knows one word in English, so I assume you and your husband exclusively speak Romanian at home.

    • The last book I read in Romanian was 9 years ago and I was reading in English before that anyway. Now I rarely read newspapers in Romanian, as I avoid getting too caught up in the news. I speak with Festus in Romanian, but with my husband we have an Rom-English sort of language. That’s not strange at all, because many [most] Romanians with tertiary education living in Bucharest are speaking a Rom-English “dialect”, as in, I use the best word to describe what I want without taking into account in which language it is. Our last jobs in Romania were at foreign-owned businesses and we talked in English with colleagues/customers.
      On top of that, for me, after reading so many books in English, making all my notes in English (including shopping lists), and chatting in the Romanian-English mix, it’s hard to speak 100% Romanian. My husband makes fun of me saying I sound like google translate when I’m talking with my mother. :))
