Bessel function Updated 2025-07-16
Shows up when trying to solve 2D wave equation on a circular domain in polar coordinates with separation of variables, where we have to decompose the initial condition in termes of a fourier-Bessel series, exactly like the Fourier series appears when solving the wave equation in linear coordinates.
For the same fundamental reasons, also appears when calculating the Schrödinger equation solution for the hydrogen atom.

Elliptic curve Updated 2025-07-16
An elliptic curve is defined by numbers and . The curve is the set of all points of the real plane that satisfy the Equation 1. "Definition of the elliptic curves"

Equation 1. "Definition of the elliptic curves" definies elliptic curves over any field, it doesn't have to the real numbers. Notably, the definition also works for finite fields, leading to elliptic curve over a finite fields, which are the ones used in Elliptic-curve Diffie-Hellman cyprotgraphy.
Bicycles require too much maintenance Updated 2025-07-16
It is true, something Ciro Santilli often things about. One likely reason is that the world is broken and most cyclist are speed maniacs willing to put the time in. Unlike Dutch people where everyone cycles.
Big O notation family Updated 2025-07-16
This is a family of notations related to the big O notation. A good mnemonic summary of all notations would be:
Bilinear form Updated 2025-07-16
Analogous to a linear form, a bilinear form is a Bilinear map where the image is the underlying field of the vector space, e.g. .
Some definitions require both of the input spaces to be the same, e.g. , but it doesn't make much different in general.
The most important example of a bilinear form is the dot product. It is only defined if both the input spaces are the same.
Binet Gaussienne Updated 2025-07-16
This is likely a joke binet, but the idea is epic: its members would in principle take the hardest courses and purposefully get bad grades on them to improve the grades of others, as grades are always normalized to a normal distribution.

Bitcoin blockchain j( upload system Updated 2025-07-16
This is likely a system that uploads text to the blockchain.
One example can be seen on the Marijuana plant.
Messages are uploaded one line per transaction, and thus may be cut up on the blk.txt, and possibly even out of order.
But because each line starts with j( you can generally piece things up regardless.
TODO identify. The first occurrence seems to be in tx e8c61e29c6b829e289f8d0fc95f9eb2eb00c89c85cfa3a9c700b15805451ae6a:
