That company's website must have gone into IP Purgatory, and could never be released as an open source website.As a student at the University of Michigan, he started a company that made lecture notes available free online, drawing a large audience of Midwestern college students and, soon enough, advertisers. At the height of the dotcom bubble, he dropped out of college, raised $10m from the venture firm Venrock and moved the company to Silicon Valley.His start-up drew interest from an acquirer that was planning to go public early in 2000. They closed the acquisition but missed their IPO window as the market plunged, and by August the company had filed for bankruptcy. Stock that Lawson and investors in his start-up received from the sale became worthless.He might actually be interested in donating to OurBigBook.com if it move forward now that he's a billionaire.

. Source. Matthew J. Holman is a figure known for his contributions to the fields of astronomy and planetary science, particularly in the study of celestial bodies within our solar system, such as asteroids and comets. He has been involved in research related to the dynamics of minor planets and has published numerous scientific papers in related areas. Additionally, he may be associated with various academic institutions or organizations in this field.
Helium has two stable isotopes, Helium-3 (\(^3\text{He}\)) and Helium-4 (\(^4\text{He}\)), and one unstable isotope, Helium-5 (\(^5\text{He}\)). 1. **Helium-3 (\(^3\text{He}\))**: This isotope has two protons and one neutron. It is relatively rare, constituting about 0.01% of naturally occurring helium.
A **sequential space** (or **sequential space**) is a type of topological space where a set is closed if it contains all the limit points of all convergent sequences contained within it.
Geodesists are professionals who specialize in geodesy, which is the science of measuring and understanding the Earth's geometric shape, orientation in space, gravitational field, and how these properties change over time. Geodesists use various techniques and technologies, including satellite positioning systems (such as GPS), traditional surveying methods, and remote sensing, to acquire precise measurements related to the Earth's surface and its dynamics.
Geodetic datums are reference frameworks used to measure the geographic coordinates (latitude, longitude, and elevation) of points on the Earth's surface. They provide a standard way to relate the positions of features on the Earth to a specific coordinate system and enable accurate mapping, navigation, and geographic information systems (GIS). ### Key Components of Geodetic Datums: 1. **Reference Ellipsoid**: This is a mathematically defined surface that approximates the shape of the Earth.
Surveying instruments are tools and devices used by surveyors and engineers to measure distances, angles, and elevations, as well as to map and analyze land and structures. These instruments are crucial for establishing precise measurements to ensure accuracy in construction, land development, and various types of civil engineering projects. Here are some common types of surveying instruments: 1. **Theodolite**: A precision instrument for measuring horizontal and vertical angles.
Geodetic astronomy is a branch of astronomy that involves the measurement of astronomical positions and their application to geodesy, which is the science concerned with the size and shape of the Earth, as well as its gravitational field. The primary objective of geodetic astronomy is to determine precise locations on the Earth’s surface in relation to celestial bodies, and to improve the understanding of the Earth's shape, dimensions, and orientation in space.
A theodolite is a precision optical instrument used for measuring angles in both horizontal and vertical planes. It is commonly utilized in surveying, engineering, construction, and various fields of geospatial science. ### Key Components of a Theodolite: 1. **Telescope**: Allows for line-of-sight measurements. 2. **Horizontal and Vertical Circles**: Graduated scales that measure angles.
Herbert Federer does not seem to be a widely recognized or notable figure in public domains such as literature, science, politics, or pop culture as of my last knowledge update in October 2023. It's possible that he may be a private individual or someone who has gained notoriety after that date.
Arithmetic geometry is a branch of mathematics that merges aspects of algebraic geometry and number theory. It primarily studies the solutions of polynomial equations and their properties over different fields, particularly over number fields and algebraic varieties. Here are some key concepts related to arithmetic geometry: 1. **Algebraic Varieties**: These are geometric objects defined by polynomial equations. They serve as the basic objects of study in algebraic geometry.
Mosaic was one of the first widely used web browsers, developed in the early 1990s. It played a significant role in popularizing the World Wide Web among the general public. Released in 1993, Mosaic was developed by Marc Andreessen and Eric Bina at the National Center for Supercomputing Applications (NCSA) at the University of Illinois.
Gerhard Thomsen is a prominent figure in seismology, known for his contributions to the understanding of seismic wave propagation and the Earth's structure. He is particularly recognized for developing methods to analyze seismic data, including techniques that help in imaging the Earth's subsurface and understanding the properties of geological formations. Thomsen has authored numerous papers and has played a significant role in advancing the field of geophysics.
Igor Rivin is a mathematician known for his work in various areas including geometry, topology, and mathematical physics. He has contributed to the understanding of mathematical concepts through research, publications, and teaching.
Mabel Minerva Young appears to be a name that may not have widely known or prominent references in public data or literature up to October 2023. It's possible she is a historical figure, a character in a piece of literature, or someone who may not have gained significant public attention.
Walter Benz is not a widely recognized figure or term as of my last knowledge update in October 2021. It’s possible that you might be referring to a specific individual not widely known or to a more recent event, concept, or product that emerged after my last update. Can you provide more context or specify what you are referring to?
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.
