These dismiss The Spirit Level as the work of state loving socialists, and are a bit short on subtlety, yet they contain many illuminating explorations of the limits and contradictions within Wilkinson and Picketts book.

Spirit level Images of the spirit sitting on a throne, or words about how advanced or wise the spirit is (especially when compared to "lesser spirits" or to you), are signs that the spirit has an inflated ego. If you are a gadget geek who simply loves experimenting with technical gadgets and do not step back from replacing batteries and powering buttons, then the Laser level measuring tool is made just for you.

WebSome spirit levels have replaceable vials, such as i-beam levels with barrel shaped vials which are set into the frame, or wood levels with banana-shaped vials. To test the vertical vial, follow the same procedure against a flat vertical surface. If the level is accurate, it will indicate the same orientation with respect to the horizontal plane.

For example Saunders finds that the relationship between inequality and the homicide rate disappears when the USA (which has high inequality and a very high rate of homicides) is excluded from the sample. For a precision machinist level with 2mm (0.079in) divisions, when the vial is tilted one division, the level will change 0.0005in (0.013mm) one foot from the pivot point, referred to by machinists as 5 tenths per foot.

Tube vials on the ends finds the true vertical. Alcohols have low viscosity and surface tension, which allows the bubble to travel the tube quickly and settle accurately with minimal interference from the glass surface. I have quoted this entire part, because it is both revealing and representative. [citation needed] This date can be established from Thevenot's correspondence with scientist Christiaan Huygens.
