    • n ruler In line-engraving, a straight steel bar supported on cleats, to which a socket is so fitted that it slides evenly and steadily backward and forward. A perpendicular tube fixed to the side of the socket holds a sharp diamond-pointed graver which is pressed down by a spring. When the socket is drawn along the bar, the graver cuts a straight line across the plate; but by a slight motion of the hand lines can be formed to suit the shape of any object.

Let us look at the ruling classification ruler: Physics and Astronomy Classification Scheme (PACS).

The first frame (S ) will have clocks and rulers whose readings we will represent by T and x.
Special and general relativity extended to allow for a variable light speed
The second frame (S ∗ ) will move in the x direction at a velocity of V = (∂x/∂T )x∗ as measured by T and x and will have clocks and rulers whose coordinates we will represent by T ∗ and x∗ .
Special and general relativity extended to allow for a variable light speed
In both cases by physical, we mean that their value can represent measurements by physical means like standard clocks and rulers, or their technological equivalents.

The theoretical template is accurate enough to test for small deviations in the phases of the oscillations, resulting from different w values. A cosmological test, using the baryonic acoustic oscillations as a standard ruler, is able to constrain w in a robust way.
Probing Dark Energy with Baryonic Acoustic Oscillations at High Redshifts
These constraints are based solely on the phase of these oscillations, assuming no errors of the value at the end of the Compton drag epoch, as the standard ruler.
Probing Dark Energy with Baryonic Acoustic Oscillations at High Redshifts
Therefore, the phases of the BAOs can be used as cosmic rulers in a similar manner as the CMB oscillations, but now at much smaller redshifts (Eisenstein, Hu & Tegmark 1998).
Probing Dark Energy with Baryonic Acoustic Oscillations at High Redshifts
The imprints of the BAOs on galaxy and clusters distributions, gravitational shear maps etc. can provide at least in principle a clean cosmic ruler for precise tests of the w parameter.
Probing Dark Energy with Baryonic Acoustic Oscillations at High Redshifts
The sound horizon s at zd is the standard ruler we are looking for.
Probing Dark Energy with Baryonic Acoustic Oscillations at High Redshifts
Though relatively small, the corrections are important as they change the length of the standard ruler s depending on k.

In the final paragraph of the introduction, Einstein stresses the importance of actual measurements of length intervals with rulers, and time intervals with clocks, in constructing the theory.

Because star formation in a given cloud can extend over considerable time, stars approaching the main sequence don’t just look younger than stars leaving, they really are (Tan et al. 2006; Subramaniam et al. 2006), though Lyra et al. (2006) note that yau can bend your rulers to make all the stars look the same age.
