Warm dark matter by Wikipedia Bot 0
Warm dark matter (WDM) is a theoretical form of dark matter that falls in energy and mass characteristics between cold dark matter (CDM) and hot dark matter (HDM). The primary distinctions among these categories relate to the speed of the particles and their thermal properties during the early universe.
Chain rule by Ciro Santilli 37 Updated +Created
Here's an example of the chain rule. Suppose we want to calculate:
So we have:
and so:
Therefore the final result is:

bsub get job stdout and stderr by Ciro Santilli 37 Updated +Created
By default, LSF only sends you an email with the stdout and stderr included in it, and does not show or store anything locally.
One option to store things locally is to use:
bsub -oo stdout.log -eo stderr.log 'echo myout; echo myerr 1>&2'
as documented at:Or to use files with the job id in them:
bsub -oo %J.out -eo %J.err 'echo myout; echo myerr 1>&2'
By default bsub -oo:
  • also contains the LSF metadata in addition to the actual submitted process stdout
  • prevents the completion email from being sent
To get just the stdout to the file, use bsub -N -oo which:
  • stores only stdout on the file
  • re-enables the completion email
as mentioned at:
Another option is to run with the bsub -I option:
bsub -I 'echo a;sleep 1;echo b;sleep 1;echo c'
This immediately prints stdout and stderr to the terminal.
Atomic, Molecular and Optical Physics by Ciro Santilli 37 Updated +Created
AMO is a slightly more general area than condensed matter physics, including related phenomena with smaller numbers atoms and optics. The two terms are however sometimes used as synonyms. The term AMO has gained wide usage and acceptability, see e.g.:
If Ciro had had greater foresight, this might have been what he studied at university!
Atomic orbital by Ciro Santilli 37 Updated +Created
In the case of the Schrödinger equation solution for the hydrogen atom, each orbital is one eigenvector of the solution.
Remember from time-independent Schrödinger equation that the final solution is just the weighted sum of the eigenvector decomposition of the initial state, analogously to solving partial differential equations with the Fourier series.
This is the table that you should have in mind to visualize them: en.wikipedia.org/w/index.php?title=Atomic_orbital&oldid=1022865014#Orbitals_table
Alexander Lerner by Wikipedia Bot 0
As of my last knowledge update in October 2023, there isn't a widely known figure or concept primarily associated with the name Alexander Lerner. It's possible that he could be a person of interest in specific fields, such as academia, literature, or another area, but without additional context, it's difficult to provide specific information.
Alfred Inselberg by Wikipedia Bot 0
Alfred Inselberg is a notable mathematician recognized for his contributions to various fields, particularly in mathematics and computer science. He is best known for developing the concept of "axis-parallel" and "parallel coordinates," which are techniques for visualizing high-dimensional data. His work in visualization has had significant implications in data analysis, scientific computing, and information visualization. In addition to his work on parallel coordinates, Inselberg has contributed to other areas, including algebra, geometry, and computer graphics.
Anatoly Morozov is a name associated with a prominent Russian scientist known for his work in various scientific fields, including physics, mathematics, or engineering. However, specific details about his contributions, research areas, and achievements may not be widely available or documented in public databases.
Arturo Rosenblueth (1900–1972) was a Mexican scientist known for his contributions to cybernetics, systems theory, and the philosophy of science. He played a significant role in the development of ideas related to communication, control systems, and the relationships between machines and living organisms. Together with Norbert Wiener and Julian Bigelow, he helped establish the field of cybernetics, focusing on the study of how systems process information and regulate themselves.
Aufbau principle by Ciro Santilli 37 Updated +Created
Boring rule that says that less energetic atomic orbitals are filled first.
Much more interesting is actually determining that order, which the Madelung energy ordering rule is a reasonable approximation to.
Bernhard Hassenstein was a notable German neuroscientist and biologist, known for his research in the fields of neurobiology and perception. He made significant contributions to the understanding of how organisms perceive visual information and process sensory inputs. Hassenstein's work has influenced studies in neuroethology, particularly in relation to the visual systems of various animal species.
Frederic Vester by Wikipedia Bot 0
Frederic Vester (1925–2010) was a German biologist, systems theorist, and environmentalist known for his work in the fields of ecological systems and the development of systems thinking. He is particularly recognized for creating the "Vester Model," a method for understanding and analyzing complex systems, particularly in relation to environmental and ecological issues. Vester's work emphasized the interconnectedness of various ecological, social, and economic factors and aimed to promote sustainable development.

Pinned article: ourbigbook/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!
We have two killer features:
  1. 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-calculus
    Articles 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.

  2. local editing: you can store all your personal knowledge base content locally in a plaintext markup format that can be edited locally and published either:
    This way you can be sure that even if OurBigBook.com were to go down one day (which we have no plans to do as it is quite cheap to host!), your content will still be perfectly readable as a static site.
