World book and copyright day, 23 April

Today is World book and copyright day. UN mentions a lot about books and the diversity of values they bring along but very few words are written on copyright per se. It’s true that books are vectors of values and knowledge, depositories of the intangible heritage. But in a world progressively going towards digital books, it could be worth having a real debate about what type of knowledge we want to preserve for the next generations, in which formats, under what types of conditions.

I was in New York recently and I was happily surprised to see the number of people still reading something (real books but also magazines, e-books, and of course their e-mails). E-book readers are more and more common, especially in planes and other public transport. Every big book store on 5th Avenue has its own e-reader, even web-based book stores promote their own e-readers. Most if not all of those e-readers promote its own closed, freedom-depriving file format.

Bill Blass Public Catalog Room - NYPL

We’ve all in mind pictures of the Rose Main Reading Room of the NYPL Schwarzman Building, where the beautiful room is packed with people reading and their laptops. I was also surprised to see the amount of computers available in other rooms (like the Bill Blass Public Catalog Room above). Books – real ones, made of paper and cardboard – are consigned to the walls, very few people are actually browsing through them. We now look for books in electronic catalog ; these books are stored in more functional room for librarians to find them. We now expose our collection of books in “social bookshelves” like librarything.

It’s not a reaction of an old man (well, maybe …). It’s more that we should think about what we want to create and what we want to leave for the next generations. It’s good to have a business plan to allow customers to have the best possible experience while reading your e-books for the next 2 years ; it’s even better if you would allow the same customers to keep their library open, transparent and “sharable” with others. Gutenberg’s invention allowed books and knowledge to be widely shared ; don’t let the “digital revolution” take that freedom back!

Eat meat or not?

It all started with a strong statement in the LA Times:

If early humans had been vegans we might all still be living in caves.

It says nothing and everything at the same time … Not eating meat would have stopped our “evolution” from early humans? Not eating meat would make us dumber? Or does it have something else to do? It does.

The original article on PLoS ONE is in fact a study about the impact of carnivory on human development and evolution. And the method used is a model of weaning in Mammals (thus no intelligence test per se). Psouni and her colleagues showed that:

  • Brain mass is a better fundamental predictor of time to weaning than is female body mass (figure 2);
  • Limb biomechanics is a predictor of time to weaning (figure 3);
  • Dietary profile is a predictor of time to weaning (figure 4) and that
  • Time to weaning in humans is quantitatively predictable from a carnivorous diet (figure 5).

So eating meat made human women wean more rapidly than if we stayed vegetarian. Their model suggests that “the contribution of carnivory was to shorten the duration of lactation and suckling despite the overall prolongation of development associated with increased adult brain mass”. Nothing about intelligence thus.

However this paper came to my knowledge after OAD published a (quite long) infographics about the dangers of red meat (not meat in general). On the presentation-side, I’m not sure such long vertical banner is powerful enough: after some time you are tired to scroll down. On the content-side, it’s a well-known fact that red meat comes with a lot of healthy risks. On top of that, the infographics focuses a lot on the USA, one of the countries where the consumption of red meat is high. This reminded me a TV programme from Jamie Oliver where he showed how meat is processed in the USA …

It’s “good” to be reminded of all this only once you’ve come back from there …

Key messages? Always read the original paper (even diagonally it’s better than general press) and know what you eat!

Edited on May 12, 2013 to remove the link to the original infographics (as it was not present anymore).
