SZÉKELYENGINEERING Tom Székely, P.E., LEED AP Newsletter Archives Home | Background and Experience | Services | Affiliations | Projects | Newsletter Archives | Newsletter Sources | Contact Us For over 30 years, Székely Engineering has produced a one-page technical/professional newsletter, Explanations and Examples , or, as a Contractor recipient has referred to it, "Engineering for Dummies," where the text to the right of each newsletter's link comprises the subject headings of the essays in that issue. Clicking the "Newsletter Sources" link in the Navigation Bar at the top of this page will take you to a similar listing describing the reference source materials linked to in each newsletter, in the event you are looking for backup or example data with regard to the points presented in a particular issue.  Text appearing in red,(with no underline; not a link) will display an inline explanatory note or definition only, as the cursor pauses over it, but only issues linked to before Volume 9 Number 1 (April 20th 2009) are HTML versions of newsletters which were originally snail-mailed (and later e-mailed as straight .pdf's), with the hand-coded HTML links so as to allow such explanatory text and definitions. Volume 9 Number 1, however, and following issues have been written with the links inserted automatically at the time of writing, with those links passed through as is by a very basic pdf converter to the .pdf versions on this site. Thus only the link URL will appear in the popup box rather than with the explanatory text of the older newsletters with hand-coded links. Explanations and Examples was optimistically intended to go out about once a month, but in actuality goes out only only every now and then (mostly then rather than now), as a .pdf e-mail attachment to over 800 recipients,  with a copy of each issue posted here as it's published. If you'd like to be added to the distribution list to receive the newsletter as its published, send us an e-mail via the 'Contact Us' link above.
