GEO600 is a gravitational wave detector located near Hannover, Germany. It is part of a global network of interferometric gravitational wave observatories that aim to detect gravitational waves, which are ripples in spacetime caused by massive astrophysical events like merging black holes or neutron stars. GEO600 consists of a 600-meter long L-shaped interferometer that uses lasers to measure minute changes in distance between mirrors positioned at each end of its arms.

This seems like a decent option, although it has bugs coming in and out all the time! Also it is quite hard to learn to use.
To get started:
  • import a clip
  • drag it onto the track area
Shortucts:
To set the video length, search for "set outpoint" on "monitor".
Add subtitles:
  • Effects
  • Dynamic text
then drag on top of the video track. To add only to part of the video, cut it up first.
Preview has no sound on Ubuntu 20.10. Fixed as of Ubuntu 22.04.
Sound worked on Ubuntu 21.04 though, but it then soon crashed with:
 = = SET EFFECT PARAM:  "rect"  =  0=1188 0 732 242
MUTEX LOCK!!!!!!!!!!!! slotactivateeffect:  1
// // // RESULTING REQUIRED SCENE:  1
Object 0x557293592da0 destroyed while one of its QML signal handlers is in progress.
Most likely the object was deleted synchronously (use QObject::deleteLater() instead), or the application is running a nested event loop.
This behavior is NOT supported!
qrc:/qml/EffectToolBar.qml:80: function() { [native code] }
Killed
amazing.
On Ubuntu 22.04 haven't crashed yet.

Worked on Ubuntu 20.10.
The UI is a bit too buggy to bear.

Clover is a telescope designed for astrophysical observations, specifically aimed at studying the cosmic microwave background (CMB) radiation. The project's full name is the "Clover" experiment, which stands for "CMB Lensing and Optical/IR Surveys." It is designed to make detailed measurements of polarization of the CMB, which can provide insights into the early universe, the nature of dark energy, and the formation of large-scale structures in the cosmos.
The Cockcroft Institute is a research and educational institution located in the United Kingdom, primarily focused on advanced accelerator science and technology. It is a collaboration between several organizations, including the University of Liverpool, the University of Manchester, and CERN, among others. The institute aims to advance the field of accelerator physics, which is critical for various applications in particle physics, medical technologies, materials science, and related fields.
The ISIS Neutron and Muon Source is a scientific facility located at the Rutherford Appleton Laboratory near Oxford, England. It is operated by the UK Research and Innovation's STFC (Science and Technology Facilities Council). ISIS provides neutrons and muons for a wide range of research applications, primarily in materials science, physics, chemistry, and biology.
MIAMI Facilities typically refers to infrastructure, services, or amenities located in Miami, Florida. However, without specific context, it can relate to various sectors such as healthcare, education, sports, and general public services.
The Particle Physics and Astronomy Research Council (PPARC) was a UK governmental body responsible for funding and supporting research in the fields of particle physics and astronomy. Established in 1994, PPARC aimed to promote and facilitate scientific advancement and education in these areas, ensuring that UK scientists could engage in high-quality research and collaborate in international projects.
The Rutherford Appleton Laboratory (RAL) is a UK-based science and technology facility located in Oxfordshire. It is part of the UK Research and Innovation (UKRI) organization and is administered by the STFC (Science and Technology Facilities Council). RAL is known for its work in various fields, including particle physics, space science, and materials science. The laboratory has several facilities, including particle accelerators, neutron and muon sources, and advanced computing resources.
TIFAC, or the Technology Information, Forecasting, and Assessment Council, is an institution in India established in 1988 under the Department of Science and Technology. Its primary objective is to promote and facilitate the development of technology in various sectors. TIFAC aims to make technology more accessible and to forecast technological advancements to support the country's growth and development.
Geology software refers to a variety of computer applications and tools that are designed to assist geologists and geoscientists in analyzing, modeling, and visualizing geological data. These software applications can serve various purposes, including: 1. **Data Management and Analysis**: Tools for storing, organizing, and analyzing geological data, such as geospatial information, rock and soil properties, and mineral content.
Pasteur's Quadrant is a concept in the field of research and innovation that categorizes different types of scientific inquiry based on their motivations and goals. The concept was popularized by Donald Stokes in his 1997 book "Pasteur's Quadrant: Basic Science and Technological Innovation." Stokes divides research into four quadrants based on two axes: 1. **The quest for fundamental understanding** (basic research) versus **the quest for use** (applied research).
Photogrammetry software is a type of application used to convert photographs into three-dimensional (3D) models and maps. It utilizes techniques from photography and geometry to measure and obtain accurate spatial information from images, typically taken from different angles. The software processes these images to identify common points, reconstructing the 3D shape and dimensions of objects or terrain.

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!
We have two killer features:
  1. 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-calculus
    Articles 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.

  2. 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.

    You can publish local OurBigBook lightweight markup files to either https://OurBigBook.com or as a static website
