Examples:
- a 2x2 matrix can represent a linear map from to , so which is a linear operator
- the derivative is a linear map from to , so which is also a linear operator
As of 2020, no one knows how to build the major desktop distros fully from source into the ISO, and especially so in a reproducible build way. Everything is done in build servers somewhere with complicated layers of prebuilds. It's crap.
The first quantum mechanics theories developed.
Their most popular formulation has been the Schrödinger equation.
Local symmetries appear to be a synonym to internal symmetry, see description at: Section "Internal and spacetime symmetries".
A local symmetry is a transformation that you apply a different transformation for each point, instead of a single transformation for every point.

Not every belongs to the elliptic curve over a non quadratically closed field Updated 2025-06-02 +Created 1970-01-01
One major difference between the elliptic curve over a finite field or the elliptic curve over the rational numbers the elliptic curve over the real numbers is that not every possible generates a member of the curve.
This is because on the Equation "Definition of the elliptic curves" we see that given an , we calculate , which always produces an element .
But then we are not necessarily able to find an for the , because not all fields are not quadratically closed fields.
For example: with and , taking gives:and therefore there is no that satisfies the equation. So is not on the curve if we consider this elliptic curve over the rational numbers.
That would also not belong to Elliptic curve over the finite field , because doing everything we have:Therefore, there is no element such that or , i.e. and don't have a multiplicative inverse.
For the real numbers, it would work however, because the real numbers are a quadratically closed field, and .
For this reason, it is not necessarily trivial to determine the number of elements of an elliptic curve.
Used to identify organic compounds.
Seems to be based on the effects that electrons around the nuclei (shielding electrons) have on the outcome of NMR.
So it is a bit unlike MRI where you are interested in the position of certain nuclei in space (of course, these being atoms, you can't see their positions in space).
What's Nuclear Magnetic Resonance by Bruker Corporation (2020)
Source. Good 3D animations showing the structure of the NMR machine. We understand that it is very bulky largely due to the cryogenic system. It then talks a bit about organic compound identification by talking about ethanol, i.e. this is NMR spectroscopy, but it is a bit too much to follow closely. Basically the electron configuration alters the nuclear response somehow, and allows identifying functional groups.Physical address extension.
With 32 bits, only 4GB RAM can be addressed.
This started becoming a limitation for large servers, so Intel introduced the PAE mechanism to Pentium Pro.
Page table structure is also altered if PAE is on. The exact way in which it is altered depends on weather PSE is on or off.

But as Scott's fame for giving away money has grown, so too has the deluge of appeals for gifts from strangers and old friends alike. That clamour may have driven Scott's already discreet operation further underground, with recent philanthropic announcements akin to sudden lightning bolts for unsuspecting recipients.
