The line running from the upper left to lower right reads mt l b < sup > c </ sup > lt.

In the IERS numerical standards, the speed of light in a vacuum is defined as c < sub > 0 </ sub > = in a vacuum, in accordance with the SI units.

The time to traverse an AU is found to be τ < sub > A </ sub > =, resulting in the astronomical unit in metres as c < sub > 0 </ sub > τ < sub > A </ sub > =.

As the speed of light in meters per second ( c < sub > 0 </ sub >) is fixed in the International System of Units, this measurement of the speed of light in AU / d ( c < sub > AU </ sub >) also determines the value of the astronomical unit in meters ( A ):

In the < tt > MixColumns </ tt > step, each column of the state is multiplied with a fixed polynomial c ( x ).

In more general sense, each column is treated as a polynomial over GF ( 2 < sup > 8 </ sup >) and is then multiplied modulo x < sup > 4 </ sup >+ 1 with a fixed polynomial c ( x ) = 0x03 · x < sup > 3 </ sup > + x < sup > 2 </ sup > + x + 0x02.

The frequency and wavelength of the gamma rays indicate that each carries 511 keV of energy ( i. e., the rest mass of an electron multiplied by c < sup > 2 </ sup >).

where n < sup > c </ sup > denotes the charge conjugate state, i. e., the antiparticle.

Ahmad Shah Durrani ( c. 1722 – 1773 ) ( Pashto /), also known as Ahmad Shāh Abdālī ( Pashto / Persian: احمد شاه ابدالي ) and born as Ahmad < u > Kh </ u > ān, was the founder of the Durrani Empire ( Afghan Empire ) in 1747 and is regarded by many to be the founder of the modern state of Afghanistan .</ poem >

Theorem: If K < sub > 1 </ sub > and K < sub > 2 </ sub > are the complexity functions relative to description languages L < sub > 1 </ sub > and L < sub > 2 </ sub >, then there is a constant c – which depends only on the languages L < sub > 1 </ sub > and L < sub > 2 </ sub > chosen – such that

: B + c < sub > 1 </ sub > · i < sub > 1 </ sub > + c < sub > 2 </ sub > · i < sub > 2 </ sub > + … + c < sub > k </ sub > · i < sub > k </ sub >.

The process terminates when ( the contents of ) B is 0, yielding the g. c. d.

This corresponds to a speed of around 0. 05 c. There is surprisingly small variation around this energy, due to the heavy dependence of the half-life of this process on the energy produced ( see equations in the Geiger – Nuttall law ).

Thus, if a two-dimensional array has rows and columns indexed from 1 to 10 and 1 to 20, respectively, then replacing B by B + c < sub > 1 </ sub >-− 3 c < sub > 1 </ sub > will cause them to be renumbered from 0 through 9 and 4 through 23, respectively.

The dental formula was i. 0 / 3, c. 1 / 1, p. 3 / 3 · 4, m. 3 / 3, the upper canines having been long sabre-like weapons, protected by a descending flange on each side of the lower front jaw.

In an " extended model " which includes hot dark matter in the form of neutrinos, then if the " physical baryon density " Ω < sub > b </ sub > h < sup > 2 </ sup > is estimated at about 0. 023 ( this is different from the ' baryon density ' Ω < sub > b </ sub > expressed as a fraction of the total matter / energy density, which as noted above is about 0. 046 ), and the corresponding cold dark matter density Ω < sub > c </ sub > h < sup > 2 </ sup > is about 0. 11, the corresponding neutrino density Ω < sub > v </ sub > h < sup > 2 </ sup > is estimated to be less than 0. 0062.

* The cofinality of the real numbers with their usual ordering is ℵ < sub > 0 </ sub >, since N is cofinal in R. The usual ordering of R is not order isomorphic to c, the cardinality of the real numbers, which has cofinality strictly greater than ℵ < sub > 0 </ sub >.

Diagram of forces acting on a segment of a catenary from c to r. The forces are the tension T < sub > 0 </ sub > at c, the tension T at r, and the weight of the chain ( 0, − λgs ).

The tension at c is tangent to the curve at c and is therefore horizontal, and it pulls the section to the left so it may be written (− T < sub > 0 </ sub >, 0 ) where T < sub > 0 </ sub > is the magnitude of the force.

It is followed by the Nihon shoki, completed in 720, and that by the Man ' yōshū, which dates from c. 771-785, but includes material that is about 400 years earlier ( Miller 1971: 4 ).

It is also used to enumerate a list in the same manner that " a, b, c, d " ( etc.

Thus we hear of abbots going out to hunt, with their men carrying bows and arrows ; keeping horses, dogs and huntsmen ; and special mention is made of an abbot of Leicester, c. 1360, who was the most skilled of all the nobility in hare hunting.

Since in oral languages the elements of sound are for the most part produced linearly in time ( that is, in a word like cat the a sound comes after the c sound, and the t sound comes after that ), they can generally be easily written in a linear ( one-dimensional ) writing system such as an alphabet.

* Let Q be a set enclosed between two step regions S and T. A step region is formed from a finite union of adjacent rectangles resting on a common base, i. e. S ⊆ Q ⊆ T. If there is a unique number c such that a ( S ) ≤ c ≤ a ( T ) for all such step regions S and T, then a ( Q )

under secction 7 ( 1 )( a ), but that section has been superseded by section 66 ( 1 ) of the Police ( Northern Ireland ) Act 1998 ( c. 32 ) which now provides that it is an offence for a person to, amongst other things, assault a constable in the execution of his duty, or a person assisting a constable in the execution of his duty.

He kills 28 people in the Trojan War, and his career during that war is retold by Roman historian Gaius Julius Hyginus ( c. 64 BC – AD 17 ) in his Fabulae.

Aeneas is also a titular character in Henry Purcell's opera Dido and Aeneas ( c. 1688 ), and one of the principal roles in Hector Berlioz ' opera Les Troyens ( c. 1857 ).

* c is the speed of light

A charge in a uniform electric field moves along a catenary ( which tends to a parabola if the charge velocity is much less than the speed of light c ).

where v is the speed of the wave ( c in a vacuum, or less in other media ), f is the frequency and λ is the wavelength.

where h is Planck's constant, is the wavelength and c is the speed of light.

In the field of high-energy particle physics, the fundamental velocity unit is the speed of light c. Thus, dividing energy in eV by the speed of light in vacuum, one can describe the momentum of an electron in units of eV / c.

It is common in particle physics, where mass and energy are often interchanged, to express mass in units of eV / c < sup > 2 </ sup >, where c is the speed of light in a vacuum ( from E = mc < sup > 2 </ sup >).

In particle physics, a system of " natural units " in which the speed of light in a vacuum c and the reduced Planck constant ħ are dimensionless and equal to unity is widely used:.

where h is the Planck constant, c is the speed of light.

In the context of this article, FTL is the transmission of information or matter faster than c, a constant equal to the speed of light in a vacuum, which is 299, 792, 458 meters per second ( by definition ) or about 186, 282. 4 miles per second.

* Light travels at speed c / n when not in a vacuum but travelling through a medium with refractive index = n ( causing refraction ), and in some materials other particles can travel faster than c / n ( but still slower than c ), leading to Cherenkov radiation ( see phase velocity below ).

On a geostationary view Alpha Centauri has a speed many times greater than c as the rim speed of an object moving in a circle is a product of the radius and angular speed.
