Igor Lomov may refer to a variety of individuals or concepts, but one prominent figure you might be referring to is a scientist or academic known for contributions in a specific field, possibly in mathematics, physics, or a related discipline. However, without more context or detail, it's challenging to provide a specific answer.
Ivan Pervushin is not widely recognized or noted in major historical, scientific, or cultural contexts. It's possible that he could be a person from a specific local context, literature, or a fictional character that is not broadly known.
As of my last update in October 2021, Khairulla Murtazin does not appear to be a widely recognized public figure, topic, or term in mainstream discourse. It's possible that he may be a local figure, an emerging personality, or someone known in specific circles or regions.
As of my last update in October 2023, there is not widely recognized information about someone named Nikolay Morozkin. It’s possible that this person could be a private individual, a less prominent figure, or someone who has gained attention after my last update.
Sergei Stepanov is a Russian mathematician known primarily for his work in the field of mathematics and computer science. His research has included contributions to areas such as graph theory, algorithm design, and combinatorial optimization. He has been involved in various mathematical projects and has published scholarly articles that explore complex mathematical concepts and their applications.
Sofya Kovalevskaya (1850–1891) was a prominent Russian mathematician, astronomer, and writer, well-known for her contributions to mathematics, especially in the fields of analysis, differential equations, and mechanics. She was the first woman in modern Europe to obtain a doctorate in mathematics, earning her degree from the University of Göttingen in Germany in 1874.
Vyacheslav Feodoritov is not a widely recognized figure in mainstream media or academic literature as of my last update in October 2023. If you're referring to a specific individual, it’s possible that he may be known in a particular niche, field, or region. Without additional context, it's difficult to provide accurate information.
Yakov Pesin is a prominent Russian-American mathematician known for his contributions to the field of dynamical systems, particularly in the theory of chaotic systems and ergodic theory. He is recognized for his work on the structure of invariant measures and the concept of the "Pesin theory" related to the behavior of dynamical systems that exhibit chaotic behavior.
The unit of electrical conductance is the siemens (S). It is defined as the reciprocal of electrical resistance, which is measured in ohms (Ω). Therefore, 1 siemens is equivalent to 1/ohm or \( S = \frac{1}{\Omega} \). Additionally, in other contexts, conductance can also be expressed in terms of mhos (℧), which is simply ohms spelled backward, although this terminology is less commonly used today.
NeuroSky is a company that specializes in the development of brainwave monitoring technology and applications. Founded in 2004, NeuroSky focuses on creating consumer and medical devices that utilize electroencephalography (EEG) to measure brain activity. Their technology often involves the use of lightweight and affordable headsets or sensors that can detect brainwave patterns and convert them into data that can be used for various applications, such as gaming, meditation, and cognitive training.
The Maurer–Cartan form is a fundamental concept in the theory of Lie groups and differential geometry, particularly in the study of Lie group representations and the geometry of principal bundles. Given a Lie group \( G \), the Maurer–Cartan form is a differential 1-form on the Lie group that captures information about the group structure in terms of its tangent space.
A "moving frame" can refer to different concepts depending on the context, including mathematics, physics, and engineering. Here are a few interpretations: 1. **Mathematics (Differential Geometry)**: In the context of differential geometry, a moving frame is often used to describe a set of vectors that vary along a curve or surface.
In music, a "key" refers to the tonal center around which a piece of music is organized. It is defined by a specific scale that serves as the foundation for melodies and harmonies within a composition. Each key is typically associated with a specific note (the tonic) and a set of pitches that can be used in the music. Keys are categorized as major or minor: 1. **Major Key**: Associated with a bright and happy sound.

This article gives an idea of how this kind of biological experiment feels like to a software engineer who has never done any biology like Ciro Santilli.
How to use an Oxford Nanopore MinION to extract DNA from river water and determine which bacteria live in it Experiment background by
Ciro Santilli 40 Updated 2025-07-16
PuntSeq is a side project led by a few University of Cambridge PhDs that aims to determine which bacteria are present in the River Cam.
In July 2019, the PuntSeq team got together with the awesome Cambridge Biomakespace, an awesome biology makerspace open to all, to create a two day science outreach activity showing their procedures.
The data collected in this experiment, together with other collection sessions done by the organizers actually led to a publication on eLife: elifesciences.org/articles/61504 "Freshwater monitoring by nanopore sequencing" by Lara Urban et al. (2021), so it is awesome to see that were are actual being part of "real science".
Ciro knows nothing about biology, but since he is very curious about it, he jumped at this opportunity, and decided to document things as well as his limited knowledge would allow.
All participants chipped in some money to help cover the experiment's costs. Ciro suspects that this activity was done partially to help crowdfund the experiment, but it was a worthy investment!
The impressions you get from the experiment as a software engineer will be:
- OMG, this is so labour intensive, why haven't they automated this
- OMG, this is frightening, all the 8 hours of work I've just done are present in that tiny plastic tube
- Amazing! Look at that apparatus! And the bio people are like: I've used this a million times, it's cheap and every lab has one, just work faster and don't break you piece of junk!
Interesting because of the Cook-Levin theorem: if only a single NP-complete problem were in P, then all NP-complete problems would also be P!
We all know the answer for this: either false or independent.
Pinned article: Introduction to the OurBigBook Project
Welcome to the OurBigBook Project! Our goal is to create the perfect publishing platform for STEM subjects, and get university-level students to write the best free STEM tutorials ever.
Everyone is welcome to create an account and play with the site: ourbigbook.com/go/register. We belive that students themselves can write amazing tutorials, but teachers are welcome too. You can write about anything you want, it doesn't have to be STEM or even educational. Silly test content is very welcome and you won't be penalized in any way. Just keep it legal!
Intro to OurBigBook
. Source. We have two killer features:
- topics: topics group articles by different users with the same title, e.g. here is the topic for the "Fundamental Theorem of Calculus" ourbigbook.com/go/topic/fundamental-theorem-of-calculusArticles of different users are sorted by upvote within each article page. This feature is a bit like:
- a Wikipedia where each user can have their own version of each article
- a Q&A website like Stack Overflow, where multiple people can give their views on a given topic, and the best ones are sorted by upvote. Except you don't need to wait for someone to ask first, and any topic goes, no matter how narrow or broad
This feature makes it possible for readers to find better explanations of any topic created by other writers. And it allows writers to create an explanation in a place that readers might actually find it.Figure 1. Screenshot of the "Derivative" topic page.
