If the Search Deeper search bar text is “Search,” the search will return results across the Org for all projects that you have access to.
Look deeper windows#
These Search Deeper windows will search within a single project. The “Search Deeper” window can also be opened for an individual project by clicking the “Search this Project” button underneath project sections in the bottom left corner or by clicking the “Search Deeper” button in the Docs Section of a project. These Search Deeper windows will search across all the projects accessible to you. Search Deeper can be opened by clicking the “Search Deeper” button in the dropdown of the “Search for a project” bar in the top right corner or by clicking the Search option from the main menu in the hamburger icon in the top left corner. Special search queries can be used in any “Search Deeper” window in Filevine, as well as in the "Search within a Project" search box. You can also improve your search results by using search query syntax. We will go over where to find Search Deeper and what Search Deeper is. Also, please explore our portfolio of Technology Transfer Case Studies.This article discusses the special syntax you can use to further specify and improve your searches within the “Search Deeper” search box. More about technologies spawned by LIGO can be found on the Technology Transfer page. Some of these 'spin-off' technologies are listed in the table below.

Innovations in areas as diverse as lasers, optics, metrology, vacuum technology, chemical bonding, and software algorithm development have resulted directly from LIGO’s pioneering work. The links below contain greater detail of some of LIGO's most impressive engineering and technology components.ĭuring its development, LIGO has already spawned innovative technology and invention. Working together, LIGO’s engineering systems and subsystems keep enough of this noise at bay for LIGO to hear the faintest whispers of gravitational waves from the depths of space. Noise, such as physical vibrations from the environment (from cars driving on nearby roads to waves crashing on distant ocean shores), quantum fluctuations within the laser itself, nanometer-scale changes in the shapes of optics, even molecules crossing the path of the laser could hamper LIGO's efforts to make its sensitive detections. Each of LIGO’s complex engineering systems, though intrinsically different, work together for one singular goal: eliminating noise. While LIGO’s search for gravitational waves relies heavily on its most prominent systems (lasers, mirrors, and photodetectors), it is the extraordinary supporting engineering and infrastructure that makes LIGO’s task even remotely possible. Achieving this degree of sensitivity requires a remarkable combination of technological innovations in precision lasers, vacuum technology, and advanced optical and mechanical systems.
How faint are these whispers? LIGO must detect a change in arm length of about 10 -19 m (10,000 times smaller than a proton).
This accomplishment was achieved because LIGO is designed to sense the infinitesimally faint whispers of gravitational waves through the imprint of that radiation on laser light. More than 40 years later, on September 14, 2015, gravitational waves were directly detected by LIGO's interferometers. Analyses of other binary neutron star systems confirmed this effect firmly concluding that gravitational waves were not just theoretical. Seven years later, after tracking the radio emissions of one star in the pair over a period of years, Taylor and two other colleagues (Joel Weisberg and Lee Fowler) noted that the time it takes for the two stars to orbit each other was decreasing exactly in a way that general relativity predicted if the two stars were radiating gravitational waves. In 1993, astrophysicists Russell Hulse and Joseph Taylor received the Nobel Prize in Physics for their 1974 discovery of a binary pair of neutron stars 21,000 light years from Earth. If you're already relatively familiar with how LIGO works, this is the place for you to delve ever deeper into LIGO's remarkable engineering. The pages in this section describe some of LIGO's most important mechanical systems in detail. Nevertheless, LIGO’s parts are remarkable in and of themselves. The whole of LIGO is so much greater than the sum of its individual parts. Super-stabilized lasers, enormous vacuum systems, the purest optics, unprecedented vibration isolation, and servo controls all work symbiotically for one singular purpose: To sense the ephemeral passage of a gravitational wave. A pair of widely-separated ground-based gravitational wave detectors, LIGO is a masterpiece of complex and sophisticated engineering.
