A single transmembrane protein that moves ATP out and ADP in of the mitochondrion. So crucial.

Present in chormosome 4.

The fact that ATP is the universal energy storage mollecule of all life on Earth is such an incredible unifying principle of biology!

It is the direct output of all the major forms of "energy generation" in cells: ATP synthesis mechanism.

It is just as fundamental as the genetic code for example.

No wonder dozens of Nobel Prizes were related to its discovery, given its complexity.

Two numbers such that the greatest common divisor is 1.

This idealization does not seems to be possible at all in the context of Maxwell's equations with pointlike particles.

Positive center is way more popular: gearspace.com/board/electronic-music-instruments-and-electronic-music-production/1222518-center-negative-vs-center-positive-power-supply.html

Ciro Santilli believes it generally hurts more than it helps.

Especially when you can't even mention censored things to criticize them. You have to pretend they never existed. So people will forget about them, and do them again in the future.

And when companies do it just to look good, even though it has absolutely no real impact on the lives of those who are discriminated against.

Given a linear operator $A$ over a space $S$ that has a inner product defined, we define the adjoint operator $A^{†}$ (the $†$ symbol is called "dagger") as the unique operator that satisfies:

The Taylor series expansion is the most direct definition of the expontial as it obviously satisfies the exponential function differential equation:

One of the main reasons why physicists are obsessed by this topic is that position and momentum are mapped to the phase space coordinates of Hamiltonian mechanics, which appear in the matrix mechanics formulation of quantum mechanics, which offers insight into the theory, particularly when generalizing to relativistic quantum mechanics.

One way to think is: what is the definition of space space? It is a way to write the wave function ${\psi }_x(x)$ such that:And then, what is the definition of momentum space? It is of course a way to write the wave function ${\psi }_p(p)$ such that:

physics.stackexchange.com/questions/39442/intuitive-explanation-of-why-momentum-is-the-fourier-transform-variable-of-posit/39508#39508 gives the best idea intuitive idea: the Fourier transform writes a function as a (continuous) sum of plane waves, and each plane wave has a fixed momentum.

PostgreSQL feels good.

Its feature set is insanely large! Just look at stuff like: stackoverflow.com/questions/1986491/sql-split-string-by-space-into-table-in-postgresql/1993058#1993058

Had a look at the source tree, and also felt good.

If Oracle is the Microsoft of database, Postgres is the Linux, and MySQL (or more precisely MariaDB) is the FreeBSD (i.e. the one that got delayed by legal issues). Except that their software licenses were accidentally swapped.

The only problem with Postgres is its name. PostgreSQL is so unpronounceable and so untypeable that you should just call it "Postgres" like everyone else.

Ubuntu 21.10 has a certain default level of logging by default to:but it does not log everything, only/mostly errors it seems.

Setting:under:and then restarting the server:just works.
