In Swedish:

Siffrorna i våra liv: Hur vi använder matematik utan att räkna,
Stefan Buijsman, Natur & Kultur, 2019.

///////

Stefan Buijsman’s book “The digits in our lives” can be seen as a contribution to the discourse around the fascinating relations between mathematics and reality. In the three thematic chapters of the book (4, 5, and 6) that deal with respectively differential and integral calculus (ch. 4), probability theory and practice (ch. 5) and graph theory and practice (ch. 6) Buijsman engages with some of the underlying mathematical concepts almost entirely without formulas – with the single exception of a linguistic verson of Bayes formula in ch. 6.

I have great respect for Buijsman’s formula-free approach and I think his book has the potential to contribute to vitalizing the public discourse around what mathematics is and how it is applied in our daily lives, especially among young people.

However, sometimes a purely textual approach leads to difficulties in clearly describing the properties of the mathematical concepts involved, which limits the understanding of their interactions. In Buijsman’s book this limitation is most clearly visible in his treatment of differential and integral calculus, where he avoids the fundamental theorem that states that differentiation and integration – when expressed properly – are inverse processes of each other. Unfortunately, in English, the verb “differentiate” does not mean “producing the differential” of a function – as one would expect – but rather “producing the derivative” of the function.

This linguistic incongruity makes it hard to carry out a more detailed discussion of the interaction of differentiation and integration. My page on Förändringsteori (= change theory) tries to throw some light on this situation – albeit in Swedish – and my page on Osäkerhetsteori (= uncertainty theory) tries to explain the connection between the concepts of integral and derivative in infinitesimal calculus, and their application counterparts, the concepts of distribution function and density function in probability theory.

Because of the many qualities present in Buijsmans formula-free descriptions of encounters with every-day mathematics that affect our lives in various ways, I have been inspired to embed his book in an “abstract space suit”, by which I mean a formula-based, and web-supported information layer “on top” of the book. This abstract layer has the potential to connect the formula-free stories to more traditional formula-based ones – mathematical stories that are “floating around” in abstract space – above the purely verbal ones.

To this aim I have made use of links to both Wikipedia and YouTube, and also to the Mathematical Explainatorium that has been created by the KMR-group at KTH over the past two decades. Hopefully, some of these formula-based stories could come under the scrutiny of some readers as a result of engaging with their verbal counterparts that are so vividly expressed in Buijsman’s book.

A book connected with abstract mathematics through an abstract space suit:

If you look at the space suit image you can see that there is a transformation going on in abstract space – from graph theory to category theory.

Overarching metaphor

Mathematics – like light – can exist and travel in vacuum. However, in the case of mathematics we are dealing with an abstract vacuum. Embedding books in abstract space suits helps them interface with this abstract mathematical vacuum

To many people abstraction seems to have a lot in common with “mental vacuum,” and therefore, abstractions are more or less unintelligible without a space suit that can connect with an inside level of “familiarity.”
