An Essay on the Psychology of Invention in the Mathematical Field

System requirements:

• Computer (Windows; MacOS X; Linux): Use a reading software that can process the file format ePUB: e.g., Adobe Digital Editions or FBReader – both free (see eBook Help).
• Tablet/Smartphone (Android; iOS): Before downloading, install the free app Adobe Digital Editions (see eBook Help).
• E-reader: Bookeen, Kobo, Pocketbook, Sony, Tolino and many more (not Kindle).

The file format ePUB works well for novels and non-fiction books – i.e., „flowing” text without complex layout. On an e-reader or smartphone, line and page breaks automatically adjust to fit the small displays.
This eBook uses Watermark-DRM, a „soft” copy protection. This means that there are no technical restrictions to prevent illegal distribution. However, there is a personalised watermark embedded in the eBook that can be used to identify the purchaser of the eBook in the event of misuse and to provide evidence for legal purposes.
