Bridge-Watching for Beginners by Edmund W. Jupp. A delightful hypertext for all who are stressed and strained and bent out of shape and feeling the need for a truss. The author says: The aim of this book is to help you to enjoy looking at bridges, by explaining in simple language some features of their design and construction. Although the technical aspects will be treated gently, and the mathematical content will be such as not to frighten the non-mathematician, maybe the serious student, too, will find something of interest here... I do hope it will help you to enjoy bridges, wherever you see them. They are such nice comfortable things to watch, especially when you know something about them.
British Columbia Ministry of Energy and Mines maintains this searchable
Process Pumps and Filtration web site.
One-stop shopping for engineering standards worldwide. Some available for
electronic download also. Even just the titles might be helpful.
An online reference library useful for equipment maintenance, suggested
by Clarice Ferreira.
The first link can sort the minerals in various ways (alphabetical, color, etc.) and is supplemented by the second link, the Extended Minerals List.This page contains almost all known names given to minerals. Well, not really (yet). But its nice. The names are linked to other hypertext linked to the glossary. Minerals Net has other useful things, also (links at bottom of the list).
Minerals Under the Microscope hypertext.
For the purposes of this demo, you will be able to search and download (at no cost to you) 8 pre-selected ASTM standards. The online store lets you purchase individual standards. Other good info on this site also.
Konstantin Lakshin passed on information about this site for the Engineering and Mining Journal. Has short versions of articles, news items, links to good industry sites, and an online form for getting a free subscription if you qualify. Of course, they will gladly SELL you a subscription if you dont...
See Eric's Treasure Troves of Science in the General section.
Radiation Manual Glossary. Basic, but helpful.
Brookhaven National Laboratory: Radiological Worker 1 Study Guide. Very
thorough, lots of good detail.
The Particle Adventure introduces the theory of fundamental particles
and forces, called the Standard Model. It explores the experimental
evidence and the reasons physicists want to go beyond this theory. In
addition, it provides information on particle decay and a brief history
section. English, French, Polish, and Spanish hypertext.
Elementary Particle glossary, taken mainly from The Particle Adventure.
McNally of the McNally Institute certainly isn't humble: he proclaims his
site is The only Centrifugal Pump & Mechanical Seal URL you will ever
need. There really is a lot of very nice practical detail here, along
with good links to other useful sites.
Very nice brief descriptions of mechanical testing and analytical
equipment used in NASA's Materials Engineering Branch. Helpful source of
basic terminology and procedures.
