In a general context, the term "series" can refer to different concepts depending on the field or discipline: 1. **Mathematics**: A series is the sum of the terms of a sequence. For example, the infinite series \( S = a_1 + a_2 + a_3 + ... \) can converge to a specific value or diverge. A well-known example is the geometric series or the Taylor series used in calculus.

Itô isometry is a fundamental concept in the theory of stochastic calculus, particularly in the context of Itô integrals. It provides an important relationship between the Itô integral and the expected value of the square of a stochastic process. Specifically, it states that the Itô integral preserves the inner product structure associated with the underlying probability space.

Setun is a computer that was developed in the Soviet Union in the 1950s. It is notable for being one of the first computers to utilize a ternary number system, which uses three digits (0, 1, and 2) instead of the binary system (0 and 1) that most modern computers use. The Setun computer was designed by a team led by Soviet scientist Sergei Alexeyevich Lebedev at the Moscow Institute of Electronic Machine Engineering.

The term "solar equator" typically refers to the imaginary line that represents the midpoint of the solar disk as seen from a particular viewpoint, such as from Earth or in the context of solar physics. In a more specific sense, within solar physics, it can also refer to the plane that bisects the Sun into the northern and southern hemispheres, analogous to the Earth's equator.

QuantLib is an open-source library for quantitative finance, primarily used for modeling, trading, and risk management in financial markets. It is written in C++ and provides a comprehensive suite of tools for quantitative analysis, including: - **Interest rate models**: Facilities for modeling and analyzing interest rate derivatives. - **Options pricing models**: Various methodologies for pricing different types of options, including European, American, and exotic options.

Nothing makes the fact that your life is an illusion clearer than animations of molecular biology processes. You just have no idea what is going on inside your own body right now!

And don't get Ciro Santilli started on the brain and the impossibility of free will.

And yet, we live, oblivious to all of it.

Amazing creators:

Basically the opposite of reductionism.

Unipept is a web-based platform designed for the analysis and interpretation of mass spectrometry-based peptide sequencing data. It provides tools for researchers to visualize and explore protein sequences, identify peptides, and understand their biological implications. Unipept allows users to input their mass spectrometry data, and it helps them identify proteins, visualize peptide occurrence and variability, and explore functional annotations.
