As of my last knowledge update in October 2021, there is no widely recognized figure by the name of Jennie Lasby Tessmann. It's possible she could be a private individual, a local figure, or someone who has gained prominence after that date. If you have any more specific context or details about her, I could help you better.

Betty Holberton (born Betty Jennings in 1917) was an American computer programmer and one of the original programmers of the ENIAC (Electronic Numerical Integrator and Computer), one of the first general-purpose electronic digital computers. Along with other women who worked on ENIAC, Holberton played a crucial role in the development of early computer programming and was instrumental in pioneering techniques that are still used in programming today.

Elizabeth Langdon Williams is not a widely recognized public figure or concept, so it’s possible that she may refer to a lesser-known individual, or perhaps you’re referring to a specific context such as an author, artist, academic, or other professional.

Hydraulic jumps are sudden changes in the flow regime of water that occur in open channel flow, such as in rectangular channels. They are characterized by a transition from supercritical flow (where the flow velocity is greater than the wave speed) to subcritical flow (where the flow velocity is less than the wave speed). This phenomenon is crucial in fluid mechanics and hydraulic engineering, as it affects the energy, momentum, and flow depth of the system.

Heron's Fountain is a classical hydraulic machine attributed to the ancient Greek engineer Hero of Alexandria. It is an example of a closed hydraulic system that demonstrates principles of fluid mechanics and pneumatic pressure. The fountain operates without any external power source and relies solely on gravity and air pressure. The design consists of a container filled with water, usually with three main parts: 1. **Upper Chamber**: This is where water is stored and can be filled.

"Ram guard" can refer to different things depending on the context. Here are a few possibilities: 1. **Automotive Accessory**: In some contexts, "Ram Guard" may refer to a protective accessory or cover designed for vehicles, specifically those made by RAM Trucks. These accessories can include items that protect the truck's body, grille, or other parts from damage.

Parflange F37 is a method of creating pipe connections that utilizes a unique flange design for joining pipes in a secure and leak-free manner. This system is often used in applications involving high-pressure and high-temperature environments. The Parflange F37 system typically involves the use of specially designed fittings that allow for the reliable connection of pipes made from various materials, such as stainless steel or carbon steel.

The Fano plane is a finite projective plane consisting of 7 points and 7 lines, with the property that each line contains exactly 3 points and each point lies on exactly 3 lines. It is the smallest projective plane and serves as a simple example in the study of combinatorial geometry and finite geometries.

In geometry, a "flag" typically refers to a specific configuration of points and subspaces in a vector space or a geometric object. More formally, a flag consists of a nested sequence of subspaces.

In projective geometry, an ovoid is a specific type of geometric structure that can be thought of as a type of surface. More formally, an ovoid is defined as a closed, convex set in a projective space such that every line intersects the ovoid in at most two points. This makes ovoids analogous to ellipsoids in Euclidean geometry.

The **Tantrasamgraha** is a significant text in the tradition of Shaiva Tantra. Attributed to the 10th-century philosopher and saint **Abhinavagupta**, the Tantrasamgraha serves as a concise summary and synthesis of various Tantric teachings and practices associated with Shaivism.

Epilogism is not a widely recognized term in modern usage, but it might refer to a few concepts depending on the context in which it's used. In general, the prefix "epi-" suggests something related to an "epilogue," which is a concluding section of a literary work that provides closure or additional commentary on the main content.

Explicature is a term used in linguistics, particularly in the field of pragmatics, to refer to the aspects of meaning that arise from the contextual interpretation of an utterance. It involves the process of elaborating the literal meaning of a sentence to include contextually relevant information that is not explicitly stated but is inferred by the listener. In transactional communication, explicature helps to clarify the speaker's intended meaning based on the context in which the utterance is made.

Braess's paradox is a concept in traffic flow and game theory that suggests that adding extra capacity to a network can sometimes lead to a decrease in overall efficiency. The paradox is named after the mathematician Dietrich Braess, who formulated it in 1968. In essence, Braess's paradox occurs when individual users of a network (such as drivers on a road network) behave in their own self-interest, and their decisions lead to a less efficient outcome for the entire system.

Khinchin's constant is a mathematical constant that appears in the context of the theory of continued fractions. Named after the Russian mathematician Aleksandr Khinchin, it is typically denoted by the symbol \( K \) and is approximately equal to \( 2.685452 \). Khinchin's constant arises in the study of the properties of the continued fraction representations of real numbers.

Immediate inference is a type of logical reasoning that allows one to draw conclusions directly from a single statement, without needing to refer to any other premises or statements. It involves deducing a specific proposition from a general one. In the context of syllogistic logic, immediate inference takes a basic form, often working with universal or categorical statements.

Inductive probability is a concept that relates to how we form beliefs or make judgments based on evidence or observations, particularly in situations of uncertainty. It contrasts with deductive reasoning, which involves drawing specific conclusions from general principles or facts. In more detail, inductive probability deals with the likelihood that a particular hypothesis or statement is true based on the evidence available.

Material inference is not a widely recognized term in mainstream academic or technical literature, so it may be context-specific or used in certain niche areas. However, the term could imply several concepts depending on the field: 1. **Material Science**: In this context, "material inference" may refer to the process of deducing properties or behaviors of materials based on experimental data or computational models.

Primordial fluctuations refer to the tiny variations in density that existed in the early universe, shortly after the Big Bang. These fluctuations are thought to have originated during the period of cosmic inflation, a rapid expansion of space that occurred within the first fraction of a second of the universe's existence. As the universe expanded, these small density variations led to regions of slightly higher and lower density.

BICEP (Background Imaging of Cosmic Extragalactic Polarization) and the Keck Array are both scientific projects focused on studying the cosmic microwave background (CMB) radiation, which is the remnant radiation from the Big Bang. ### BICEP The BICEP experiment was designed to detect and measure the polarization of the CMB, particularly to search for patterns that may indicate the presence of gravitational waves produced during the inflationary period of the early universe.
