For any element, the mass number is equal to the atomic weight rounded off to the nearest integer value. The proton has a positive charge that is equal in magnitude, but opposite in polarity, to the charge of an electron. The number of protons defines how many extranuclear electrons an ...

This unit is the basis for determining the relative atomic weight for all other elements. A hydrogen atom is assigned an atomic weight of 1 (rounded from 1.008) because the mass of a hydrogen atom is roughly equal to 1/12th the mass of a carbon-12 atom (depicted on the right). ...
Facilitated transport rates can reach ~1000 translocation events or a mass flow of 100 MDa per NPC per second6, and NPC passage of a single molecule is usually completed within milliseconds to tens of milliseconds7,8,9, even for ribosomal subunits10. In fact, passage through the NPC barrier...
This concept involves a nuclear means of producing and focusing a high-density, extremely high-velocity gas (Nuclear Howitzer) or, by means of a second interaction, a mass of high velocity, solid pellets (CASABA) into an angle of about 2°-4°. The desired effect of this concept is a ...
A launch laser or mass driver powerful enough to boost huge masses into orbit can smash a combat starship like a sledge-hammer hitting a cockaroach. If there is a planetary disaster, spaceports will suddenly be thrust into the role of operational center. After all, it will be the source ...
Space pirates need infrastructure (fences for pirated loot, fuel and reaction mass, ship repairs, R&R for the crew). A hidden planetary base can act as a Pirate Haven and cater to these needs. Planetary Defense Armed military station defending its planet from outside attack, planetary fortress...
Galactic a galaxy, most or all of its stars, up to all mass associated with it. Universal the entire universe, all or most galaxies within it, or all major galaxy filaments or equivalent highest-level structures. Multiversal multiple universes, or whatever that exists outside of the setting'...
Alpha : (kg/kW) power plant mass in kilograms divided by kilowatts of power. So if a solar power array had an alpha of 90, and you needed 150 kilowatts of output, the array would mass 90 * 150 = 13,500 kg or 13.5 metric tons Specific Power : (W/kg) watts of power divided by...
