In differential geometry and general relativity , the Bach tensor is a trace-free tensor of rank 2 which is conformally invariant in dimension n = 4 . [ 1 ] Before 1968, it was the only known conformally invariant tensor that is algebraically independent of the Weyl tensor . [ 2 ] In abstract indices the Bach tensor is... | https://en.wikipedia.org/wiki/Bach_tensor |
Bachelor of Electrical Engineering ( B.E.E. or BEE ) is an undergraduate academic degree offered to a student who completes three to five years of study in electrical engineering at a university or college.

Lagrange's four-square theorem , also known as Bachet's conjecture , states that every nonnegative integer can be represented as a sum of four non-negative integer squares . [ 1 ] That is, the squares form an additive basis of order four: p = a 2 + b 2 + c 2 + d 2 , {\displaystyle p=a^{2}+b^{2}+c^{2}+d^{2},} where the ... | https://en.wikipedia.org/wiki/Bachet's_conjecture |
In mathematics, the Bachmann–Howard ordinal (also known as the Howard ordinal , or Howard-Bachmann ordinal [ 1 ] ) is a large countable ordinal .
It is the proof-theoretic ordinal of several mathematical theories , such as Kripke–Platek set theory (with the axiom of infinity ) and the system CZF of constructive set the... | https://en.wikipedia.org/wiki/Bachmann–Howard_ordinal |

In a screen of the Bacillus subtilis genome for genes encoding ncRNAs , Saito et al. focused on 123 intergenic regions (IGRs) over 500 base pairs in length, the authors analyzed expression from these regions. Seven IGRs termed bsrC, bsrD, bsrE, bsrF, bsrG, bsrH and bsrI expressed RNAs smaller than 380 nt. All the small... | https://en.wikipedia.org/wiki/Bacillus_subtilis_BSR_sRNAs |
Bacillus virus Φ29 (bacteriophage Φ29) is a double-stranded DNA (dsDNA) bacteriophage with a prolate icosahedral head and a short tail that belongs to the genus Salasvirus , order Caudovirales , and family Salasmaviridae .

In theoretical physics , back-reaction (or backreaction ) is often necessary to calculate the self-consistent behaviour of a particle or an object in an external field.
When a particle is considered to have no mass or to have an infinitesimal charge, this can be described as saying that we deal with a probe and that b... | https://en.wikipedia.org/wiki/Back-reaction |
Back-story , in the production of consumer goods , is information about the effects of their production.
