Wolfgang Haack could refer to a few different things depending on the context, but there is no widely known figure or concept that stands out with this name in popular culture, science, or history as of my last update in October 2023. It’s possible that Wolfgang Haack might be a less prominent individual in academia, business, or other areas not covered broadly in available datasets.
Wolfgang Liebe does not appear to be a widely recognized or notable figure in popular culture, science, or history based on the data available up until October 2023. It's possible that he may be a private individual, or the name could refer to someone with local significance or a specific context not broadly documented.
W. H. Besant refers to Sir Walter Besant, an English novelist, historian, and biographer who was active in the late 19th and early 20th centuries. He is well-known for his works of fiction, many of which are set in London and often explore themes related to social issues and the lives of ordinary people. Besant also played a significant role in promoting the study of London’s history and wrote extensively about the city.
Non-Newtonian fluids are fluids whose viscosity changes with the applied shear stress or shear rate, in contrast to Newtonian fluids, which have a constant viscosity regardless of the applied stress. In simpler terms, the flow behavior of non-Newtonian fluids is dependent on the conditions under which they are subjected to force.
Walter Munk was a renowned American oceanographer and physicist, often referred to as the "Einstein of the Oceans." Born on October 19, 1917, and passing away on February 8, 2023, he made significant contributions to our understanding of ocean wave dynamics, tides, and climate. Munk was particularly noted for his work in acoustic oceanography and his role in the development of techniques for measuring ocean currents and waves.
"Sunday" is a song by the British rock band Foals, featured on their album *Everything Not Saved Will Be Lost – Part 2*, released in 2019. The song encapsulates themes of love, longing, and the passage of time, characterized by its dynamic instrumentation and emotive lyrics. It showcases Foals' signature sound, blending elements of rock, art rock, and electronic music.
In fluid dynamics, the Laplace equation is often applied in the context of irrotational flow, which is characterized by the absence of vorticity. For an incompressible, irrotational flow, the flow velocity can be described with a potential function, commonly denoted as \( \phi \).
Eddy diffusion is a process that describes the transport and mixing of particles, heat, or other substances in a medium, such as air or water, due to turbulent eddies or vortices. This phenomenon is particularly important in the fields of fluid dynamics, meteorology, oceanography, and environmental science. In turbulent flows, eddies of varying sizes are created as a result of chaotic fluid motion.
The Emerson Cavitation Tunnel is a specialized facility used for testing and studying cavitation phenomena in fluid dynamics, particularly in relation to marine and hydraulic applications. Cavitation occurs when a liquid is subjected to rapid changes in pressure, leading to the formation of vapor bubbles. These bubbles can collapse violently, causing damage to surfaces and affecting the performance of propellers, pumps, and other fluid machinery. Emerson's facility typically includes a long, submerged tunnel where water is circulated at controlled velocities.
How to use an Oxford Nanopore MinION to extract DNA from river water and determine which bacteria live in it Why Oxford Nanopore was used instead of Illumina for the sequencing by
Ciro Santilli 37 Updated 2025-07-16
At the time of the experiment, Illumina equipment was cheaper per base pair and dominates the human genome sequencing market, but it required a much higher initial investment for the equipment (TODO how much).
The reusable Nanopore device costs just about 500 dollars, and about 500 dollars (50 unit volume) for the single usage flow cell which can decode up to 30 billion base pairs, which is about 10 human genomes 1x! Note that 1x is basically useless for one of the most important of all applications of sequencing: detection of single-nucleotide polymorphisms, since the error rate would be too high to base clinical decisions on.
Compare that to Illumina which is currently doing about an 1000 dollar human genome at 30x, and a bit less errors per base pair (TODO how much).
Other advantages of the MinION over Illumina which didn't really matter to this particular experiment are:
- portability for e.g. to do analysis on the field near infections outbreaks. Compare that to the smallest Illumina sequencer currently available in 2019, the iSeq 100: Figure 1. "Illumina iSeq 100 DNA sequencer".
- long reads which can be necessary for long repetitive regions, see also: Section "Sequence alignment"
Hans-Beat Bürgi is a Swiss mathematician known for his contributions to various areas of mathematics, particularly in the field of number theory, combinatorics, and mathematical education. He has been recognized for his work in explaining complex mathematical concepts in an accessible manner and has published numerous papers and educational materials.
This channel contains several 2D continuous simulations and explains AI techniques used.
The engine appears to be open source: github.com/Primer-Learning/PrimerTools (previously at: github.com/Helpsypoo/primer). Models are closed source however.
They have several interesting multiagent game ideas.
Ciro became mildly jealous of this channel when he found out about it, because at 800k subscribers at the time, the creator is likely able to make a living off of it, something which Ciro thought impossible.
As of 2022 he was at 1.6M followers with only 17 videos! Of course, much of those videos is about the software and they require infinite development hours to video time ratios.
Well done!
Created by Justin Helps. Awesome name.
To make things better, the generically named channel is also the title of one of the best films of al time: Primer (2004).

xdg-open out/index.htmlJean-Baptiste L. Romé de l'Isle was a French mineralogist and geologist, best known for his work in crystallography during the 18th century. He made significant contributions to the understanding of crystal structures and the principles of crystallography. One of his notable works is the formulation of the "law of symmetry" in crystals, which contributed to the classification of crystals based on their geometric shapes and symmetry properties.

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.
