On Napier's work on logarithms:
"The Invention was greedily embraced (and deservedly) by Learned Men." - 1685 by Dr. John Wallis, Savilian Professor of Geometry, University of Oxford. (Ref. 5.)
"The Canon Mirificus is the first British contribution to the mathematical sciences, and next to Newton's Principia it is the most important work in the history of the exact sciences that has been published in Great Britain, at all events until within the memory of living persons.
In whatever country the Canon Mirificus had been produced, it would have occupied the same commanding position, for it announced one of the greatest scientific discoveries ever made."
- 1915 by J. W. L. Glaisher, M.A., Sc.D, F.R.S, Fellow of Trinity College, Cambridge. (Ref. 7)
Introduction: In 1614 John Napier of Scotland published his Mirifici Logarithmorum Canonis Descriptio, a treatise on logarithms together with tables related to the present natural logs. Although not as well known as other groundbreaking books on mathematics / science, it certainly deserves to be so as the use of logarithms was far reaching in e.g. mathematics, astronomy, navigation, finance. It was translated into English by Edward Wright in 1618 and published with the title A Description of the Admirable Tables of Logarithmes (9). The English mathematician Henry Briggs in liaison with Napier constructed tables of logs to the base ten which became the base most widely used. 2014 is the 400th anniversary of Napier's first publication and the Royal Society of Edinburgh has a webpage devoted to 'Napier 400' summarising the events being planned, which include a free exhibition 'Power of Ten: Inventing Logarithms' by National Museums Scotland and some meetings.
Nowadays with calculators or smartphone apps an arms length away providing answers to complex calculations in sub-seconds to umpteen decimal places, its easy to forget how valuable logarithms became when Napier's work was published—as Wallis eloquently summarised in header quote—they were 'greedily embraced'. The potential of logarithms to transform complex multiplication and division to much simpler and less error prone operations using addition and subtraction was quickly recognised, both in tabular form and as logarithmically ruled scales in the form of the Gunter's scale and slide rules. Other workers (8) who are known to have contributed to logarithms and/or exponents include Archimedes (4) and Michael Stifel. Jost Bürgi independently developed his own method for creating logarithmic tables but published later in 1620. Napier's rods (or bones) are a manual calculating device which Napier devised.
As a collector of slide rules and
with a casual interest in the history of mathematical tables, this article is my own modest 'raising a glass' to Napier on the 400th anniversary by sharing a gallery of collectables
with a wider logarithmic theme—as
to date only two have been identified that are directly associated with John
Napier. In 2006 Werner Rudowski
shared a splendid illustrated article covering the theme
of 'Logarithms, Slide Rules and Abaci on Stamps, Coins and
Banknotes' (1). I don't wish to overlap his presentation so I
concentrate on collectables either published since 2006 or
on how known items have been variously presented. I would be
interested to learn of other items.
John Napier and other mathematicians:
Above: In 2012 a set of 21 stamps depicting
mathematicians in the Deutsche Post 'Marke Individuell'
series did feature a portrait of Napier, the only stamp to
my knowledge published to date that does. The title page of
his 'Descriptio' is also incorporated (left above).
Fortuitously the series also included the German monk and
mathematician Michael Stifel whose work is cited by
historians in the history of logarithms and exponents. The
stamp shows a page from his 'Arithmetica Integra' published
in 1544 (see Wikipedia
entry).
These 'Marke Individuell' series
are end user designs submitted to Deutsche Post for approval
but are valid post. The series looks professionally designed
and do wonder who instigated them, perhaps an institution in
Germany. The individual stamps and full set were previously
available on delcampe.net but has been replaced at time of
writing by an extensive new set of mathematicians and their work.
Note added Jan. 19th 2014. Thank you to Werner Rudowski who remarks: "One can order a block of 20 stamps, each 60 cents for a total of €39.85, i.e. each one would cost about €2."
Note added October 25th 2015. The above stamps were designed and issued by Dieter Egelriede who sells them on delcampe.net under his delcampe ID 'Pzbrig2'. With thanks to Dieter for a personal communication.
Nicaragua, 1971, 'Las 10
formulas matematicas que cambiaron la faz de la
tierra' ('10 mathematical formulas that changed
the face of the earth' - Google Translation).The sea, stars and sextant
emphasise the profound impact that logarithms had on
navigation / astronomy. Illustrated by Werner Rudowski
(1), to date this and the German stamp above, are
possibly the only two known devoted to John Napier.
A short
biography is presented on the stamp's reverse. A neat idea that
could be more widely adopted to describe the theme of
a stamp.
Charles Babbage and philately: The
majority of logarithmic themed collectables found to date
present Charles Babbage and his work. Babbage needs no
introduction and is well known for his ambition to build
mechanical engines using the method of differences to both
calculate and print out error free and accurate tables
including logarithms. His difference engine designs were
never completed but the Science Museum UK successfully built
his Difference Engine No. 2 in time for the bicentennial of
his birth on December 26th 2001 (6). The printer was later successfully built and added.
Both were shown to work very well. (See below for notes on his
Analytical Engine.)
Great Britain, 1991, 'Scientific
Achievements'. A stamp showing a profile of a youthful
Babbage and a stylised illustration of the method of
differences formed part of the Royal Mail 'Scientific
Achievements' series. Werner Rudowski illustrated this stamp
in ref. 1 remarked on above, but also featured in his
fascinating article 'Images of Charles Babbage' discussing and
illustrating portraits / photos of Babbage that are known (3). The latter
article is useful in identifying which portrait was used where
featured in stamp / first day cover designs. Below are
additional presented examples of how the Babbage stamp in this
series was featured.

Left above: Republic of Guinea-Bissau, 2007, 'Grandes Inventions'. An attractive stamp with an older portrait of Babbage and engine.
Right above: Gabon Republic, 2001, invention of calculator. A cleverly thought out design incorporating part of a Babbage engine in background and showing the transition from mechanical to thermionic valve to modern integrated circuit calculator designs. Correction Sept. 28th 2018. A discrete transistor is shown not a valve! The progression shown in the design is thus from Babbage's to later mechanical calculators, discrete transistors then to modern calculators which typically use single chip microprocessors for calculation.
Other Babbage themed collectables. The Isle of Man in 1999 issued an attractive FDC featuring a design with Babbage portrait on the envelope and an Isle of Man 1995 one crown coin embedded 'Inventions of the Modern World'. The coin has a stylised design of his analytical engine. This fomed part of the 'Millennium Coin Cover Series'. This is available from a variety of stamp/coin dealers.
Some test currency notes printed by De La Rue also featured intricate designs showing a portrait of Babbage and aspects of his technical drawings. delcampe.net sometimes sell these.
Babbage and trains: I'm not a train buff but while 'Googling' for Babbage related items I stumbled on an attractive detailed working model of a British Rail Class 60 diesel locomotive. Wikipedia informs us that the Class 60 was first in service in 1989 and designed for 'heavy freight' duties such as aggregate, coal and petroleum. The engine numbered 60054 was given the 'Charles Babbage' nameplate. Wiki' notes that examples in this class for coal / petroleum use were named after those who had contributed to science or engineering.
For the collector of all things logarithmic, if ever an excuse was needed to persuade our families that a train set was justified—here's a good reason! Working model locomotives with this detail are quite expensive (typically £70+ on eBay UK), so I'm grateful to a dealer for a photograph of this model.

Slide rules and philately: Slide rules and their scales use the principles of logarithms to provide powerful and versatile tools for a range of calculations. The first slide rules were developed only a few years after Napier's publications in 1622 by William Oughtred and others. To my knowledge there are at least ten stamps that show a recognisable slide rule in its design although some examples are admittedly in the 'blink and you'd miss it' category!
Below are all the stamps either previously reported or have come across myself to date that show a slide rule (there are no doubt more), plus a selection of first day covers that feature them on the envelope design. Eking out some examples were a direct result of seeing what photographs depicting a scientist with slide rule had been used on a stamp. The Crick and Watson, Whittle, Fermi and Segrè examples below were found this way with the help of Mike Konshak's splendid gallery of 'Historical Photos of People with Slide Rules and Related Ephemera' on his International Slide Rule Museum website.
A Crick and Watson photo with DNA model: One of the iconic photos that presents Crick and Watson in front of their DNA model shows a slide rule being used as the pointer by Francis Crick. A fascinating and poignant article in the UK Slide Rule Gazette (2) described and illustrated the story behind this series of photographs (and featured on the Gazette's front cover). Some stamps and other philately items have used this photograph as shown below.
Left above:
Australia 2003. Maximum card. Collecting maximum cards is
a formal branch of philately called maximaphily. They are
cards with the stamp placed on the front of a commercial
postcard where the subject of the postcard, stamp and
postmark show a high degree of concordance. See 'Microscopy
themed maximaphily',
Micscape February 2013.
Middle above and detail to the right:
Great Britain 2009. Cambridge University 800th
anniversary, commemorative sheet CS6. The unlabelled stamp
attached to the postage stamp showing Crick and Watson is
called a 'se-tenant label' and a form regarded to be
a legitimate thematic (with thanks to members of the
Stamp Community Forum for clarifying
its terminology). © Stamp Design Royal Mail Group Ltd (2009).
Above: Togo (République Togolaise) in the 1990s published a series of Millennium sheets celebrating aspects of different decades from the 20th century. This sheet for the 1950s uses the same iconic photo of Crick and Watson (top right of sheet, detail on right).
Left and middle above: Romania, 1957, 'AL2-LEA Congress' depicting a stylised slide rule. These were illustrated by Werner Rudowski in his 2006 article (1).
Right above: German Democratic Republic, 1962, mechanical engineering? A 'blink and you'd miss it example' but believe a slide rule is shown.
Republic of the Congo, 1964, University Lovanium 20th anniversary. The far left stamp forms part of an adhesive sheet of unperforated stamps, the middle and right are discrete perforated stamps. Again the slide rule barely features but collectors of such a very narrow theme can't be too fussy!
Russia 2012, Marina M Raskova, female pilot and navigator, celebrating 100 yrs since her birth. See Wikipedia entry for a biography. An attractive design with sufficient detail for knowledgeable collectors to recognise as a real slide rule model and thought to be 'an early NL-type' (with thanks to Ronald van Riet, see discussion on Yahoo International Slide Rule group ).
USA First day cover 2001. This is again based on a photograph of Fermi and both the photograph and this FDC are shown in the International Slide Rule Museum gallery. The back of the envelope states the image source: 'Original painting for the First Day Cover by Gherman Komlev. Authorised by Ms. Rachel Fermi.' © Fleetwood.
