From their site:
OCM Genesis is our flagship generative art collection that's set many historic precedents since its launch in 2021. Genesis is the first NFT collection where all 10,000 images and metadata (similar to DNA describing the NFT) were generated using code entirely on-chain in a single transaction on Ethereum. With the launch of Bitcoin Ordinals, Genesis is the first ever collection of 10,000 images to be inscribed on Bitcoin in 2023.
Some of their likely transactions were noted in our list of large transactions: github.com/cirosantilli/bitcoin-inscription-indexer/blob/master/data/payload_size_out e.g.:but we haven't had the patience to index them properly yet. Boring art anyways.

The Quadratic Integrate-and-Fire (QIF) model is a mathematical representation used to describe the behavior of a neuron. It builds upon the simpler Integrate-and-Fire (IF) model by incorporating quadratic nonlinearity to more accurately represent the dynamics of action potentials (spikes) in neurons.

In the context of mathematics, "NSMB" typically stands for "Non-Smooth Multivalued Banach" space or "Non-Smooth Multivalued Behavior," but it's important to note that these specific acronyms may not be widely recognized outside specialized areas in mathematical research. In broader contexts, "NSMB" could refer to various topics based on the specific field or subfield of mathematics being discussed.
An analog computer is a type of computing device that uses continuous physical quantities to represent information. Unlike digital computers, which process data in discrete binary values (0s and 1s), analog computers work with real-world phenomena and can model variables such as voltage, current, mechanical movement, or fluid pressure. ### Key Characteristics of Analog Computers: 1. **Continuous Data Representation**: Analog computers represent data in a continuous form.
Mortar methods typically refer to techniques used in various fields such as construction, masonry, and computing (specifically in relation to certain algorithms). However, without additional context, it is challenging to pinpoint exactly which aspect you're referring to. 1. **Construction and Masonry**: In construction and masonry, mortar methods refer to the techniques and types of mortar used to bond bricks, stones, or other masonry units together.
Mimesis in mathematics refers to the concept of imitation or representation of real-world phenomena through mathematical models and constructs. This concept is grounded in the idea that mathematics can be used to describe, simulate, or replicate the patterns, structures, and behaviors observed in nature and various domains of human activity.
Metrication in Chile refers to the process of converting measurements and units from the imperial system to the metric system. This transition began in the 19th century and was largely completed in the mid-20th century, aligning with international trends promoting the metric system as a standard. In Chile, metrication involved adopting units such as meters, liters, and kilograms for length, volume, and weight, respectively. The goal was to improve consistency, efficiency, and compatibility with global trade and scientific research.

At some point it stopped using Bitcoin mainline and moved to Bitcoin Cash instead: www.newsbtc.com/news/bitcoin/cryptograffiti-rejects-bitcoin-core-bch-now-available-payment-method/ and therefore became useless. Existing indexes seem to have been broken as well.
Also, based on the timing of Figure "Erich Erstu", this service may be responsible for a large part of the raw JPEG images present in the blockchain from block 416527 (2016) onwards. This is also suggested by the comments at Figure "Tank Man".
A Quantitative Analysis of the Impact of Arbitrary Blockchain Content on Bitcoin gives the interesting insight that all its transactions seem to return change/fees to one or two given addresses, thus making it very easy to list all their uploads if they were consistent! So all we need are some starting points, which we have mostly due to ASCII mentions of the site on known inscriptions, all of which have a few common spent addresses at the very end:so we just have to solve get all Bitcoin transactions from and to a given address and we are done.

Mean Field Annealing is a technique used in statistical mechanics, optimization, and machine learning, particularly in the context of spin systems and combinatorial optimization problems. It combines concepts from mean field theory and simulated annealing. ### Key Concepts: 1. **Mean Field Theory**: This is a statistical approach used to analyze complex systems by approximating all interactions with an average field, rather than considering individual interactions between particles or variables.
The Maxwell–Fricke equation describes the relationship between the diffusion coefficients of a solute in various states, specifically in terms of the concentration gradient and other physical parameters. It is often presented in the context of diffusion processes and can be used to model how particles move and spread in a medium, particularly in fluid dynamics and electrochemistry. The equation is derived from principles of statistical mechanics and considers factors such as temperature, viscosity, and concentration gradients to relate the mobility of particles to the diffusion process.

Their main techniques seem to be:and:mkdir binout for file in blk*dat; do echo "$file"; binwalk --dd='.*' "$file" -C binout/. --log=binout/"$file""res.txt"; done
which seem promising.mkdir subfileout for file in blk*dat; do mkdir subfileout/"$file"; done for file in blk*dat; do echo "$file"; hachoir-subfile --category=image,video,audio,container,archive,misc "$file" subfileout/"$file" > subfileout/"$file""subfile.txt"; done

The 74181 is a popular integrated circuit (IC) that functions as a 4-bit arithmetic logic unit (ALU). It was developed by Texas Instruments and introduced in the early 1970s. The 74181 is capable of performing various arithmetic and logic operations on 4-bit binary numbers, such as addition, subtraction, and Boolean logic operations like AND, OR, and XOR.
Mathematical programming with equilibrium constraints (MPEC) is a type of optimization problem that involves finding an optimal solution while satisfying certain equilibrium conditions, which are often described by complementarity conditions or variational inequalities. MPECs are particularly useful in areas where the decision-making process is influenced by equilibrium relationships, such as economics, engineering, and operations research.

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. View it live at: ourbigbook.com/go/topic/derivativeVideo 2. OurBigBook Web topics demo. Source. - 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.
- to OurBigBook.com to get awesome multi-user features like topics and likes
- as HTML files to a static website, which you can host yourself for free on many external providers like GitHub Pages, and remain in full control
