In physics, electromagnetic radiation (EMR) consists of waves of the electromagnetic (EM) field, which propagate through space and carry momentum and electromagnetic radiant energy. Types of EMR include radio waves, microwaves, infrared, (visible) light, ultraviolet, X-rays, and gamma rays, all of which are part of the electromagnetic spectrum.
In particle physics, the electroweak interaction or electroweak force is the unified description of two of the four known fundamental interactions of nature: electromagnetism (electromagnetic interaction) and the weak interaction. Although these two forces appear very different at everyday low energies, the theory models them as two different aspects of the same force. Above the unification energy, on the order of 246 GeV, they would merge into a single force. Thus, if the temperature is high enough – approximately 1015 K – then the electromagnetic force and weak force merge into a combined electroweak force. During the quark epoch (shortly after the Big Bang), the electroweak force split into the electromagnetic and weak force. It is thought that the required temperature of 1015 K has not been seen widely throughout the universe since before the quark epoch, and currently the highest human-made temperature in thermal equilibrium is around 5.5x1012 K (from the Large Hadron Collider).
In statistics, an expectation–maximization (EM) algorithm is an iterative method to find (local) maximum likelihood or maximum a posteriori (MAP) estimates of parameters in statistical models, where the model depends on unobserved latent variables. The EM iteration alternates between performing an expectation (E) step, which creates a function for the expectation of the log-likelihood evaluated using the current estimate for the parameters, and a maximization (M) step, which computes parameters maximizing the expected log-likelihood found on the E step. These parameter-estimates are then used to determine the distribution of the latent variables in the next E step. It can be used, for example, to estimate a mixture of gaussians, or to solve the multiple linear regression problem.
"Reveille", called in French "Le Réveil" is a bugle call, trumpet call, drum, fife-and-drum or pipes call most often associated with the military; it is chiefly used to wake military personnel at sunrise. The name comes from réveille, the French word for "wake up".
In materials science, shear modulus or modulus of rigidity, denoted by G, or sometimes S or μ, is a measure of the elastic shear stiffness of a material and is defined as the ratio of shear stress to the shear strain:
The Goldman–Hodgkin–Katz voltage equation, sometimes called the Goldman equation, is used in cell membrane physiology to determine the Resting potential across a cell's membrane, taking into account all of the ions that are permeant through that membrane.

Fair Em, the Miller's Daughter of Manchester, is an Elizabethan-era stage play, a comedy written c. 1590. It was bound together with Mucedorus and The Merry Devil of Edmonton in a volume labelled "Shakespeare. Vol. I" in the library of Charles II. Though scholarly opinion generally does not accept the attribution to William Shakespeare, there are a few who believe they see Shakespeare's hand in this play.

In chemistry, the effective molarity is defined as the ratio between the first-order rate constant of an intramolecular reaction and the second-order rate constant of the corresponding intermolecular reaction or the ratio between the equilibrium constant of an intramolecular reaction and the equilibrium constant of the corresponding intermolecular reaction.

Get 'Em Girls is the second studio album by Australian recording artist Jessica Mauboy, released on 24 August 2010 by SRC Records and Universal Republic Records. Mauboy recorded the album in Los Angeles, New York City and Atlanta. She worked with various American songwriters and producers she had not worked with before, including Bangladesh, Harvey Mason Jr., Chuck Harmony, Brian Kennedy, and Alex James, among others. Musically, Get 'Em Girls contains up-tempo and ballad-oriented songs, which derive from the genres of pop, hip hop and R&B. The album features guest vocal appearances from Snoop Dogg, Ludacris, Jay Sean, and Iyaz.
"Brother Rapp" is a 1970 funk song written and performed by James Brown. It was first released as a two-part single on King Records (K6285) in early 1970, but was quickly withdrawn from sale. It was released again later that year in a mechanically sped-up version that charted #2 R&B and #32 Pop. It also appeared on the album Sex Machine with overdubbed crowd noise, and Brown later issued it in a faded version with different guitar work, in 1973 for the Slaughter's Big Rip-Off soundtrack album. A live version of "Brother Rapp" is included on the album Love Power Peace.
"America Is My Home" is a 1968 single by James Brown. It was intended as a patriotic song written by Brown and Hayward E. Moore, recorded in 1967 in response to increasing criticism of the Vietnam War by black leaders such as Martin Luther King Jr. and Stokely Carmichael. Brown speaks rather than sings the words of the song over an instrumental backing. The lyrics affirm that "America is still the best country, without a doubt" and claim "black and white, they may fight, but if the enemy come we'll get together and run 'em out of sight." Brown delayed the song's release until the summer of 1968 when he thought the timing was right. It charted #13 R&B and #52 Pop. He followed it later that year with "Say It Loud - I'm Black and I'm Proud".
"Killing Is Out, School Is In", titled "School Is In" on its single version, is a song recorded by James Brown with additional vocals by Bobby Byrd and Tomi Rae Hynie. It was released in 2001 as a CD single but failed to chart. It was Brown's last single and also appeared as the closing track on his 2002 album The Next Step.
Trap Happy Porky is a 1945 Warner Bros. Looney Tunes short directed by Chuck Jones and written by Tedd Pierce. The short was released on February 24, 1945, and features Porky Pig, along with Hubie and Bertie, an early version of Claude Cat and a prototype of Hector the Bulldog.
