"Comptech" could refer to various entities or concepts depending on the context, as it is not a unique term. Here are a few possibilities: 1. **Company Names**: There are several companies with "Comptech" in their names, often involved in technology solutions, IT consulting, software development, or computer services. For specific details, it would be necessary to look at the specific business being referenced.
This useless video doesn't really explain anything, he just says "it's needed because the equation has an in it".
The real explanation is: they are not needed, they just allow us to write the equation in a shorter form, which is always a win: physics.stackexchange.com/questions/32422/qm-without-complex-numbers/557600#557600
We've come across a few shallow and stylistically similar websites on suspicious ranges with this pattern.
No JS/JAR/SWF comms, but rather a subdomain, and an HTTPS page with .cgi extension that leads to a login page. Some names seen for this subdomain:
The question is, is this part of some legitimate tooling that created such patterns? And if so which? Or are they actual hits with a new comms mechanism not previously seen?
The fact that:suggests to Ciro that they are an actual hit.
- hits of this type are so dense in the suspicious ranges
- they are so stylistically similar between on another
- citizenlabs specifically mentioned a "CGI" comms method
In particular, the
secure
and ssl
ones are overused, and together with some heuristics allowed us to find our first two non Reuters ranges! Section "secure subdomain search on 2013 DNS Census"Some currently known URLsIf we could do a crawl search for

that might be a good enough fingerprint, maybe even *.*com/cgi-bin/*.cgi
. Edit: it is not perfect, but we kind of did it: Section "secure subdomain search on 2013 DNS Census".Can be achieved in two ways it seems:
- macroscopic beam splitter and optical table
- photolithography
Animation of Hong-Ou-Mandel Effect on a silicon like structure by Quantum Light University of Sheffield (2014): www.youtube.com/watch?v=ld2r2IMt4vg No maths, but gives the result clear: the photons are always on the same side.
- quantum dot source. TODO how do you produce identical photons from two separate quantum dots? See also: quantum dot single photon source.
- superconducting nanowire detector. So the device has to be cooled then? Video "Jeremy O'Brien: "Quantum Technologies" by GoogleTechTalks (2014)" youtube.com/watch?v=7wCBkAQYBZA&t=2497 however says that semiconducting devices can also be used
The approach many courses take to physics, specially "modern Physics" is really bad, this is how it should be taught:
- start by describing experiments that the previous best theory did not explain, see also: Section "Physics education needs more focus on understanding experiments and their history"
- then, give the final formula for the next best theory
- then, give all the important final implications of that formula, and how it amazingly describes the experiments. In particular this means: doing physics means calculating a number
- then, give some mathematical intuition on the formulas, and how the main equation could have been derived
- finally, then and only then, start deriving the outcomes of the main formula in detail
This is likely because at some point, experiments get more and more complicated, and so people are tempted to say "this is the truth" instead of "this is why we think this is the truth", which is much harder.

Francisca Nneka Okeke is a Nigerian physicist and professor known for her work in the field of physics, particularly in areas related to space and atmospheric sciences. She has made significant contributions to the understanding of the ionosphere and its impact on radio wave propagation. Additionally, Okeke is an advocate for promoting science education and has been involved in various initiatives to encourage young women and girls to pursue careers in science and technology.
In abstract algebra, a branch of mathematics that deals with algebraic structures, theorems serve as fundamental results or propositions that have been rigorously proven based on axioms and previously established theorems. Here are some significant theorems and concepts in abstract algebra: 1. **Group Theory Theorems**: - **Lagrange's Theorem**: In a finite group, the order (number of elements) of any subgroup divides the order of the group.
Embedding, in the context of machine learning and natural language processing (NLP), refers to a technique used to represent items, such as words, entities, or even entire documents, in a continuous vector space. These vectors can capture semantic meanings and relationships between the items, allowing for effective analysis and processing. ### Key Points about Embeddings: 1. **Dense Representation**: Unlike traditional representations (e.g., one-hot encoding), embeddings provide a more compact and informative representation.
Emmy Noether was a prominent mathematician known for her groundbreaking contributions to abstract algebra and theoretical physics. Her bibliography includes numerous papers and articles, primarily in German and French, reflecting her work on algebraic structures, ring theory, and Noetherian rings, among other topics.
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.
