    • n Mars A Latin deity, identified at an early period by the Romans with the Greek Ares, with whom he had originally no connection. He was principally worshiped as the god of war, and as such bore the epithet Gradivus; but he was earlier regarded as a patron of agriculture, which procured him the title of Silvanus, and as the protector of the Roman state, in virtue of which he was called Quirinus. In works of art Mars is generally represented as of a youthful but powerful figure, armed with the helmet, shield, and spear; in other examples he is bearded and heavily armed. See cut under Ares.
    • n Mars The planet next outside the earth in the solar system. Its diameter (about 4,200 miles) is only 0.53 that of the earth, its superficies 0.28, and its volume 0.147. Its mean density is 0.71 that of the earth, so that the density of its crust may very likely be about the same as the earth's; but the weight of a given mass at the surface of Mars is only three eighths of the weight of the same mass on the earth. The strength of materials is therefore relatively much greater there, and mountains, animals, and buildings would naturally be much larger. The mean distance from the sun is 141,500,000 miles. The eccentricity of its orbit is very much greater than that of the earth, being 0.093 in place of 0.017; the inclination of its equator to its orbit is about the same. Its day is half an hour longer than ours. Its year is 687 of our days. The surface of Mars has been carefully mapped, and is characterized by the predominance of land and the great number of canals or straits. Its color is strikingly red. Its climate is, perhaps, not very different from that of the earth. It has two moons, discovered by Professor Asaph Hall in Washington in 1877, conformably to the prediction of Kepler, and realizing the fancies of Swift and of Voltaire. The inner of these, Phobos, revolves in less than 8 hours, so that to an observer on the planet it rises in the west and sets in the east; the outer, Deimos, revolves in 30 hours, so that it appears nearly stationary for a long time. The symbol of Mars is ♂, which seems to show the shield and spear of the god.
    • n Mars In old chemistry, iron.
    • n Mars In heraldry, the tincture red, when blazoning is done by the planets: see blazon.

Venture the tree and a myriad such,
When nothing you mar but the year can mend:
But a last leaf—-fear to touch!

Bidding me praise

Must Fortune keep you far?

Who share the unlit place with me—
Those stones out under the low-limbed tree
Doubtless bear names that the mosses mar.

In science:

This problem is very timely, as it is also confirmed by the very recent exam by Mar´ın-Franch et al. (2009b) of the influence, of CNO and helium variations, on the relative age determination of GCs, purely from a theoretical point of view.
The influence of the C+N+O abundances on the determination of the relative ages of Globular Clusters: the case of NGC 1851 and NGC 6121 (M4)
Let us look at the final comparison between the two clusters under discussion in the analysis of De Angeli et al. (2005) and Mar´ın-Franch et al. (2009a) summarized in Table 1.
The influence of the C+N+O abundances on the determination of the relative ages of Globular Clusters: the case of NGC 1851 and NGC 6121 (M4)
Here we report the result for the Carretta & Gratton (1997) abundances, and for the models by Cassisi et al. (2004) in De Angeli, and by Dotter et al. (2007) in Mar´ın-Franch.
The influence of the C+N+O abundances on the determination of the relative ages of Globular Clusters: the case of NGC 1851 and NGC 6121 (M4)
The comparison in Figs. 1 and 2 has shown that the two clusters we are considering may differ in age by about 2 Gyr (as found by Mar´ın-Franch et al. 2009a).

The eigenvalue density of the matrix (1/T )ξ ξ T is known to converge to the Marˇcenko-Pastur law ρ∗ (λ) = p(λ+ − λ)(λ − λ− )/(2πrλ), where λ± = (1 ± r)2 and r = N/T in the limit N → ∞, r = const [Mar67].
Heavy-tailed random matrices
We use the method of moments to show that for k > 1 the largest eigenvalue is still approximately (1+pp/dk )2 and the spectral density approaches that of the Marˇcenko-Pastur law, generalizing the random matrix theory result to the random tensor case.
Random tensor theory: extending random matrix theory to random product states
Our asymptotic estimates for em p,d,k also imply that the limiting spectral density of Mp,d,k is given by the MarˇcenkoPastur law, just as was previously known for the k = 1 case.
Random tensor theory: extending random matrix theory to random product states
Consequently, the aforementioned results in the literature can be rederived rather simply using the formulas in Section 2 by substituting µX with the semicircle measure (for Wigner matrices), the Marˇcenko-Pastur measure (for Wishart matrices) or the free Jacobi measure (for Jacobi matrices ).
The eigenvalues and eigenvectors of finite, low rank perturbations of large random matrices
Any historical estimator is inevitably marred by the measurement noise; it will reflect the true covariances only to a certain degree, with a superimposed broadening due to the finiteness of the time series.

However, other limiting distributions do appear in the theory: for example, the Wishart matrices themselves (i.e., without the partial transposition) converge to the so-called Marčenko–Pastur law (see section 2.3).
