The Acorn Electron is a budget version of the BBC Micro educational / home computer made by Acorn Computers Ltd.

There are at least 500 known games for the Electron and the true total is probably in the thousands.

If Acorn had thought to include this small modification in the original Electron design it is likely the machine would have had a much greater impact as it would have nearly doubled the amount of motion possible in games and saved modes 0 – 3 ( including the only 16 colour mode ) from being nearly useless due to contended memory timings.

The Electron is widely misquoted as operating at 1. 79 MHz after measurements derived from speed testing against the thoroughly 2 MHz BBC Micro for various pieces of ' common software '

Notable popular games particularly associated with the Electron include: Crystal Castles ( video game ) | Crystal Castles is an example of a popular arcade game officially ported to the Electron ( US Gold ).

Electron software is predominantly archived in the UEF file format.

Electron degeneracy pressure is a quantum-mechanical effect arising from the Pauli exclusion principle.

Electron gas can undergo plasma oscillation, which is waves caused by synchronized variations in electron density, and these produce energy emissions that can be detected by using radio telescopes.

Electron beam lithography ( EBL ) is a method of etching semiconductors at resolutions smaller than a micron.

Electron beam processing is used to irradiate materials in order to change their physical properties or sterilize medical and food products.

The Transmission Electron Aberration-corrected Microscope is capable of sub-0. 05 nm resolution, which is more than enough to resolve individual atoms.

Electron counting is a formalism used for classifying compounds and for explaining or predicting electronic structure and bonding.

# Electron in the initial state is represented by a solid line with an arrow pointing toward the vertex (→•).

# Electron in the final state is represented by a line with an arrow pointing away from the vertex: (•→).

Electron beam lithography is also important commercially, primarily for its use in the manufacture of photomasks.

Electron beam lithography as it is usually practiced is a form of maskless lithography, in that a mask is not required to generate the final pattern.

Electron beam lithography ( often abbreviated as e-beam lithography ) is the practice of scanning a beam of electrons in a patterned fashion across a surface covered with a film ( called the resist ), (" exposing " the resist ) and of selectively removing either exposed or non-exposed regions of the resist (" developing ").

Electron capture is the main decay mode for isotopes lighter than the < sup > 51 </ sup > V.

* July 10 – Donald Crowhurst's trimaran Teignmouth Electron is found drifting and unoccupied.

Electron paramagnetic resonance, otherwise known as Electron Spin Resonance ( ESR ) is a spectroscopic technique similar to NMR, but uses unpaired electrons instead.

In histology, Stage I ( Minimal Mesan gial ) disease looks normal under light microscopy, but mesangial deposits are noted in Electron Microscopy.

In Electron Microscopy, subendothelial deposits are noted, and some mesangial changes may be present.

These include the arcade adventure Castle Quest ( BBC only ) by Tony Sothcott, billed as " Probably the most challenging game ever devised for the BBC Micro " ( it was never converted for the Electron, probably because it used near full-screen scrolling in an 8-colour mode ), Doctor Who and the Mines of Terror ( BBC, C64, CPC ), a huge arcade adventure that required its own ROM chip to run on the Model B BBC Micro, and the puzzle / platform game Imogen ( BBC only, later ported to Electron by Superior Software and more recently remade for PC ) by Michael St. Aubyn which was noted for its witty, original puzzles and cute high-resolution monochrome graphics.

Electron states are best represented by time-depending " mixtures " ( linear combinations ) of multiple orbitals.

This enabled the Electron to achieve the same functionality as that provided by the Expansion-ROM slot on the bottom-left of the BBC Micro B keyboard.

An unusual variant of the Electron was sold by British Telecom Business Systems as the BT Merlin M2105 Communications Terminal.

Like the BBC Micro, the Electron was constrained by limited memory resources.

Although not as well supported by the biggest software publishers as rivals like the Commodore 64 and Sinclair ZX Spectrum, a good range of games were available for the Electron.

Despite Acorn themselves effectively shelving the Electron in 1985, games continued to be developed and released by professional software houses until 1991.

This includes the Optical Microscope, Transmission Electron Microscope, Scanning Electron Microscope, Fluorescence Microscope, and by Confocal Microscopy.

The standardized 1N-series numbering EIA370 system was introduced in the US by EIA / JEDEC ( Joint Electron Device Engineering Council ) about 1960.

The European Pro Electron coding system for active components was introduced in 1966 and comprises two letters followed by the part code.

Electron microscope constructed by Ernst Ruska in 1933

The first detection of tau neutrino interactions was announced in summer of 2000 by the DONUT collaboration at Fermilab, making it the latest particle of the Standard Model to have been directly observed ; its existence had already been inferred by both theoretical consistency and experimental data from the Large Electron – Positron Collider.

In 1962-70 negotiations took place between the Cambridge Electron Accelerator Laboratory ( shared by Harvard and the Massachusetts Institute of Technology ), the Stanford Linear Accelerator Center, and the US Atomic Energy Commission over the proposed 1970 construction of the Stanford Positron Electron Asymmetric Ring ( SPEAR ).

* Electron magnetic dipole moment, the magnetic moment of an electron caused by its intrinsic property of spin

Electron capture is the primary decay mode for isotopes with a relative superabundance of protons in the nucleus, but with insufficient energy difference between the isotope and its prospective daughter ( with one less positive charge ) for the nuclide to decay by emitting a positron.

* Electron beam, a stream of electrons observed in vacuum tubes

Electron cyclotron resonance is a phenomenon observed in plasma physics, condensed matter physics, and accelerator physics.

Electron microscopy is widely used to obtain images with nanometer level resolution but the relatively thick living cell cannot be observed as the sample has to be chemically fixed, dehydrated, embedded in resin, then sliced ultra thin.
