You can reach me by email. I invite questions, corrections, constructive criticism and complaints (polite ones) with the following caveats:
I do have a day job (surprising isn’t it), I will respond to all polite emails but not necessarily instantly.
I can’t offer detailed engineering advice about specific problems (e.g. why does that valve blow all the fuses when I try to open it), but I will offer pearls of wisdom about less specific software issues.
I don’t know anything about car engines or kettles so please don’t ask.
For the more emotionally tainted, my dogs, Hector and Henry, are Salukis and while it may be off topic I have a soft spot for them and I may be willing to discuss them if pushed.
If your email comes down to “I think your website’s rubbish, I won’t pay for it, but I do want to shout at you for a while about your outrageous shortcomings” then please, there is no need to trouble yourself; you’ve already said everything by not paying.
So if you’re happy with that, you can reach me here:firstname.lastname@example.org.
Thanks to everyone who has paid for this website. Your contributions are appreciated.
Thanks to the dogs: Hector (left) and Henry (right) their advice was invaluable.
Most of the images in the website are my own or of my creation (which probably explains the poor quality).
The exceptions are the photographs of Capital magazine in Figure 3.1; these images are reproduced courtesy of the Herb Lubalin Study Center at The Cooper Union (41 Cooper Square, Room LL119, New York) — lubalincenter.cooper.edu.
In Figure 3.4, the three images of Chester are courtesy of Michael D. Beckwith and the image of the Houses of Parliament is courtesy of Samel Zeller. The image of the metal type face (Figure 3.9) is by Hannes Wolf. All these images are via the unsplash website and are used under the creative common zero licence (reproduce below).
The fonts used were created by Mr Matthew Butterick and are Equity (serif), Concourse (sans serif) and Triplicate (monospace); I refer to them collectively on the website as the Equity fonts. If you want to use them you can buy them here.
The downloadable version of the website uses the open source fonts: PT Serif, Source Sans Pro, PT Mono, Carrois Gothic SC and Andada Regular SC. These are available from.font squirrel.
The website uses various third-party software and files, I hope I’ve adequately and correctly made notification of them on the website and in the source code — I do so again here:
|Conditions various html tags so that they are rendered consistently in different browsers|
(Google hosted library )
|jQuery library used to run the jQuery scripts|
|Caleb Troughton||Used to detect when to switch to fixed navigation bar (has many other uses)|
|Mathias Nater||Dynamically hyphenates text within a web page|
|Used to display code fragments within a html page|
|Lokesh Dhakar||Used to overlay images on top of the current page|
|MathJax||Renders AsciiMath, TeX/LaTeX and MathML code as standard mathematical notation|
|Third-party software running on the website|
Normalise, Hyphenator, Lightbox and Waypoints are available under the Github MIT licence (reproduced below) and jQuery, MathJax and Prettify are available under the Apache 2.0 licence (also reproduced below):

SIL Open Font License v1.10
The goals of the Open Font License (OFL) are to stimulate worldwide development of collaborative font projects, to support the font creation efforts of academic and linguistic communities, and to provide a free and open framework in which fonts may be shared and improved in partnership with others.
The OFL allows the licensed fonts to be used, studied, modified and redistributed freely as long as they are not sold by themselves. The fonts, including any derivative works, can be bundled, embedded, redistributed and/or sold with any software provided that any reserved names are not used by derivative works. The fonts and derivatives, however, cannot be released under any other type of license. The requirement for fonts to remain under this license does not apply to any document created using the fonts or their derivatives.
“Font Software” refers to the set of files released by the Copyright Holder(s) under this license and clearly marked as such. This may include source files, build scripts and documentation.
“Reserved Font Name” refers to any names specified as such after the copyright statement(s).
“Original Version” refers to the collection of Font Software components as distributed by the Copyright Holder(s).
“Modified Version” refers to any derivative made by adding to, deleting, or substituting—in part or in whole—any of the components of the Original Version, by changing formats or by porting the Font Software to a new environment.
“Author” refers to any designer, engineer, programmer, technical writer or other person who contributed to the Font Software.
