Electron

The electron is a subatomic particle, symbol e− or β−, with a negative elementary electric charge. Electrons belong to the first generation of the lepton particle family, and are generally thought to be elementary particles because they have no known components or substructure. The electron has a mass that is approximately 1/1836 that of the proton.Quantum mechanical properties of the electron include an intrinsic angular momentum (spin) of a half-integer value in units of ħ, which means that it is a fermion. Being fermions, no two electrons can occupy the same quantum state, in accordance with the Pauli exclusion principle. Like all matter, electrons have properties of both particles and waves, and so can collide with other particles and can be diffracted like light. The wave properties of electrons are easier to observe with experiments than those of other particles like neutrons and protons because electrons have a lower mass and hence a higher De Broglie wavelength for typical energies.

Electron (bird)

Electron is a genus of the motmots, a family of Neotropical near passerine birds. The genus has two species:

Both inhabit humid evergreen tropical forest. Both occur in Central America, and the broad-billed motmot occurs in a large region of South America as well.

They are distinguished from other motmots by their much wider bills. The rackets on their tails are less dramatic than those of many other motmot species and may be absent. The species are very similar except in adult plumage (but the adult keel-billed resembles the juvenile broad-billed). A mixed pair apparently courting has been observed (Howell and Webb 1995).

The name Electron is a Latinization of the Ancient Greek word for amber, and can mean "bright" in scientific names (Jaeger 1978). The name was given 46 years before an elementary particle was named electron.

History

Rocket Lab was founded as a New Zealand firm. As of mid-2014, media sources continued to refer to Rocket Lab as a New Zealand company.

Former Crown Research scientist Peter Beck is its founder, CEO and Technical Director. Internet entrepreneur Mark Rocket was the seed investor and co-Director from 2007 to 2011.

In December 2010 Rocket Lab was awarded a US contract from the Operationally Responsive Space Office (ORS) to study a low cost space launcher to place nanosatellites into orbit.

Funding has been obtained from Bessemer Venture Partners, Callaghan Innovation, in 2014, and from Khosla Ventures in 2013.

In February 2015, Rocket Lab USA was evaluating Cape Canaveral Air Force Station as a possible launch site.

Beloved (film)

Beloved is a 1998 American horror-drama film based on Toni Morrison's 1987 novel of the same name, directed by Jonathan Demme and starring Oprah Winfrey, Danny Glover, and Thandie Newton. The plot centers on a former slave after the American Civil War, her haunting by a poltergeist, and the visitation of her reincarnated daughter whom she murdered out of desperation to save her from a slave owner. Despite being a box office bomb,Beloved received an Academy Award nomination for Best Costume Design for Colleen Atwood, and both Danny Glover and Kimberly Elise received praise for their performances.

Plot

Sethe is a former slave living on the outskirts of Cincinnati shortly after the Civil War. An angry poltergeist terrorizes Sethe and her three children, causing her two sons to run away forever. Eight years later, Sethe (Oprah Winfrey) lives alone with her daughter, Denver (Kimberly Elise). Paul D. (Danny Glover), an old friend from Sweet Home, the plantation Sethe had escaped from years earlier, finds Sethe's home, where he drives off the angry spirit. Afterwards, Paul D. proposes that he should stay and Sethe responds favorably. Shortly after Paul D. moves in, a clean, mentally handicapped young woman (Thandie Newton) named Beloved stumbles into Sethe's yard and also stays with them.
