Opens a virtual MIDI piano GUI. It just works on Ubuntu 20.04: askubuntu.com/questions/34391/virtual-midi-piano-keyboard-setup/1298026#1298026

VMPK is a virtual device that replicates what you would get by connecting a physical MIDI keyboard to your computer. It is not a software synthesizer on its own. But it does connect to a working synthesizer by default (Sonivox EAS) which makes it produce sounds out-of-the box.

TODO: then I messed with my sound settings, and then it stopped working by default on the default "MIDI Connection" > "MIDI Out Driver" > "Network". But it still works on "SonivoxEAS".

A hello world of actually connecting it to a specific software synthesizer manually on Advanced Linux Sound Architecture with aconnect can be found at: askubuntu.com/questions/34391/virtual-midi-piano-keyboard-setup/1298026#1298026

Reasonable default key mappings to keyboard covering 2 octaves.

3 multiple simultaneous keys did not work (tested "ZQI"). This might just be a limitation of my keyboard however.

Small microscopic visible particles move randomly around in water.

If water were continuous, this shouldn't happen. Therefore this serves as one important evidence of atomic theory.

The amount it moves also quantitatively matches with the expected properties of water and the floating particles, was was settled in 1905 by Einstein at: investigations on the theory of the Brownian movement by Einstein (1905).

This suggestion that Brownian motion comes from the movement of atoms had been made much before Einstein however, and passed tortuous discussions. Subtle is the Lord by Abraham Pais (1982) page 93 explains it well. There had already been infinite discussion on possible causes of those movements besides atomic theory, and many ideas were rejected as incompatible with observations:The first suggestions of atomic theory were from the 1860s.

Tiny uniform plastic beads called "microbeads" are the preferred 2019 modern method of doing this: en.wikipedia.org/wiki/Microbead

Original well known observation in 1827 by Brown, with further experiments and interpretation in 1908 by Jean Baptiste Perrin. Possible precursor observation in 1785 by Jan Ingenhousz, not sure why he wasn't credited better.

Rafael Bombelli (1526–1572) was an Italian mathematician, known primarily for his work in algebra. He is best known for his contributions to the understanding of complex numbers and for developing rules for operations involving imaginary numbers. His most significant work, "L'Algebra" (published in 1572), laid foundational principles for manipulating these numbers, laying the groundwork for future developments in algebra and mathematics.

Sorin Popa can refer to different individuals or contexts, as the name may belong to various people. Without specific context, it's difficult to determine which Sorin Popa you are referring to. There may be noted individuals in fields such as sports, academia, or business with that name.

A projective representation is an extension of the concept of a group representation, which is commonly used in mathematics and theoretical physics. In a standard group representation, a group \( G \) acts on a vector space \( V \) through linear transformations that preserve the vector space structure. Specifically, for a group representation, there is a homomorphism from the group \( G \) into the general linear group \( GL(V) \) of the vector space.

As of my last knowledge update in October 2023, there is no widely recognized figure named Vladimir Andrunakievich in politics, science, or popular culture. It's possible that he could be a private individual or a lesser-known person who has come to prominence after that time.

Fair division protocols are mathematical and algorithmic methods used to allocate resources among multiple parties in a way that is considered fair and equitable. These protocols are often applied in various contexts, such as dividing goods, resources, or even tasks among individuals, families, or groups. The objective is to ensure that each participant feels that they have received a fair share based on agreed-upon criteria.

Digit-by-digit algorithms are computational methods used primarily to perform arithmetic operations such as addition, subtraction, multiplication, and division on numbers, particularly large numbers, by processing one digit at a time. These algorithms can be especially useful in contexts where numbers cannot be easily handled by conventional data types due to their size, such as in cryptography or arbitrary-precision arithmetic. ### Key Characteristics 1.

The Chandy–Misra–Haas (CMH) algorithm is a distributed deadlock detection algorithm that operates within a resource model where processes and resources are represented as nodes in a directed graph. This algorithm is designed to detect deadlocks in systems where resources can be allocated to processes and where processes can request additional resources. ### Key Components of the CMH Algorithm Resource Model: 1. **Processes and Resources**: - The system consists of multiple processes and resources.

Distributed tree search refers to a computational method used to solve problems that can be represented as trees, leveraging a distributed system to improve efficiency and scalability. It is commonly employed in fields like artificial intelligence, operations research, and optimization problems, particularly in contexts where the search space is large. In a typical tree search, nodes represent states or decisions, and branches represent the possible actions or transitions between these states.

Kinodynamic planning is a concept in robotics and motion planning that involves considering both the kinematics (the geometric aspects of motion) and the dynamics (the forces and torques that enable motion) of a robot or a moving object. The goal of kinodynamic planning is to find a feasible trajectory for a robot that satisfies both its physical constraints and the environment's constraints.

Otto E. Neugebauer (1899–1990) was a prominent Austrian-American mathematician and historian of mathematics, best known for his work in the fields of ancient and medieval astronomy and mathematics. His research focused particularly on the mathematical practices and astronomical models of ancient cultures, including those in Babylon, Egypt, and Greece. Neugebauer's contributions include the study of cuneiform texts and the mathematical ideas embedded in them, along with the development of concepts in ancient science.

The Shapiro-Senapathy algorithm is a method used in the field of data classification and clustering, particularly for analyzing and processing time series data. It is named after its creators, Dr. Walter Shapiro and Dr. P. R. Senapathy. The algorithm is designed to identify patterns and trends within data, making it useful for various applications, including financial analysis, signal processing, and any context where temporal data is examined.

Pointer jumping is a technique used in computer programming, particularly in the context of data structures and algorithms, to efficiently navigate or manipulate linked structures such as linked lists, trees, or graphs. While the term is not universally defined, it generally refers to two main concepts: 1. **Efficient Navigation**: Pointer jumping can refer to the method of using pointers to quickly skip over certain nodes or elements in a data structure.

"Virtually" can refer to a few different concepts depending on the context: 1. **Adverbial Meaning**: In general usage, "virtually" means "almost" or "nearly," suggesting that something is true in effect but not in an absolute sense. For example, if someone says "I virtually finished the project," it implies that they are very close to finishing, but not quite there yet.

Judith R. Goodstein is an American physicist and educator known for her work in the field of physics education and communication. She is particularly recognized for her efforts in making physics accessible to a broader audience and her contributions to the teaching and understanding of physics. Goodstein has also been involved in various educational initiatives aimed at improving science education. In addition to her academic endeavors, she has authored books and has been active in various scientific organizations.

David Pingree (1933–2005) was a notable American historian of science, particularly known for his work on the history of astronomy and mathematics in ancient cultures, particularly in the context of Hellenistic and Islamic traditions. He made significant contributions to the understanding of the transmission of knowledge between cultures, exploring how Greek science influenced later developments in medieval Islamic science and subsequently in Europe.
