neper

From Joannes Neper, the Latinized name of John Napier, a Scottish mathematician.

Values of b, the amplitude attenuation constant, are given for various materials in Table 1.1. Having dimensions of [length]⁻¹, it is usually measured in nepers per centimetre (Np cm⁻¹).

1994, T. G. Leighton, The Acoustic Bubble, page 28:

The unit of α is nepers per meter. It can be easily seen that if a line has an attenuation constant of 1 neper/m, a unit amplitude voltage wave will reduce to e⁻¹ over a distance of 1 meter.

2006, R. K. Shevgaonkar, Electromagnetic Waves, page 15:

The attenuation constant for the phantom muscle tissue is αₘ = 10.0 nepers/m.

Regarding definition 3: the etymology is either that electric circuits used to be prototyped on actual bread boards (definition 1) populated with nails, or that solder breadboards have lots of holes and are usually brown (they visually resemble a slice of bread), or a merging of the two. The etymology is less obvious today given the popularity of solderless breadboards.

If you are following a book like Starting Electronics, however, a breadboard is even more useful. […] Differences lie between breadboards in the spacings and the positionings of the holes, and the number of holes in each group.
