Ive been spending the last month working on my LinkedIn profile. Setting up a group that will hopefully evolve into a space where people can discuss the best ways to get there posts viewed by a wider audience. This is proving much more difficult than I initially assumed. I managed to find an iphone app that allows you to publish posts at prime times in the day, to optimise viewing figures.

Come join my group!

I was trained to prepare a new test today (abstract taken from another website):

The particle-size distribution, or ‘grading’, is a fundamental property for all construction aggregates and often defines the product. Grading is usually carried out by sieve analysis. The sample is passed through a sieve stack (wet or dry) and the weight proportion retained on each sieve is determined. The cumulative percentage finer than each sieve size is plotted to produce ‘grading curves’. Aggregate should be clean (free of clay, silt and dust) to ensure effective binding of cement or bitumen. Sedimentation methods may also be used to determine the grading of fines. 

 An old documentary found on the BBC iplayer 'Strangeness Minus Three' has a short tutorial by the great Richard Feynman. Of the many quotes attributed to him is the statement that 'to truly understand something you must be able to teach it',  something he does very well in this 1960's tv show. Its a perfect example that if something is complicated then the problem is not fully understood.

Ive been given a book from work called The Manual For Soil Testing (by K.H. Head), it breaks down the science behind the every day tests that I do. A breakdown of my notes can be found here.
