SLAC National Accelerator Laboratory

SPEAR (originally Stanford Positron Electron Asymmetric Rings, now simply a name) was a collider at the SLAC National Accelerator Laboratory. It began running in 1972, colliding electrons and positrons with an energy of 3 GeV. During the 1970s, experiments at the accelerator played a key role in particle physics research, including the discovery of the J/ψ meson (awarded the 1976 Nobel Prize in physics), many charmonium states, and the discovery of the tau (awarded the 1995 Nobel Prize in physics). Today, SPEAR is used as a synchrotron radiation source for the Stanford Synchrotron Radiation Lightsource (SSRL). The latest major upgrade of the ring in that finished in 2004 rendered it the current name SPEAR3.

The Stanford Synchrotron Radiation Lightsource (formerly Stanford Synchrotron Radiation Laboratory), a division of SLAC National Accelerator Laboratory, is operated by Stanford University for the Department of Energy. SSRL is a National User Facility which provides synchrotron radiation, a name given to electromagnetic radiation in the x-ray, ultraviolet, visible and infrared realms produced by electrons circulating in a storage ring (Stanford Positron Electron Asymmetric Ring - SPEAR) at nearly the speed of light. The extremely bright light that is produced can be used to investigate various forms of matter ranging from objects of atomic and molecular size to man-made materials with unusual properties. The obtained information and knowledge is of great value to society, with impact in areas such as the environment, future technologies, health, biology, basic research, and education.[1]SSRL provides experimental facilities to some 2,000 academic and industrial scientists working in such varied fields as drug design, environmental cleanup, electronics, and x-ray imaging.[2] It is located in San Mateo County, in the city of Menlo Park, California, close to the Stanford University main campus.

The PULSE Institute (PULSE) is an independent laboratory of Stanford University, founded in 2005 for the purpose of advancing research in ultrafast science, with particular emphasis on research using the Linac Coherent Light Source at the SLAC National Accelerator Laboratory. Recent research programs include Terahertz radiation (sometimes called T-rays) ultrafast studies and attosecond pulse studies. It is housed in the Central Laboratory on the grounds of SLAC, and also utilizes some laboratory space on the main Stanford campus nearby. Philip H. Bucksbaum was named as the first director of PULSE. In 2019 David A. Reis became the PULSE director.

Sand Hill Road, often shortened to just "Sand Hill" or "SHR", is an arterial road in western Silicon Valley, California, running through Palo Alto, Menlo Park, and Woodside, notable for its concentration of venture capital firms. The road has become a metonym for that industry; nearly every top Silicon Valley company has been the beneficiary of early funding from firms on Sand Hill Road.Its significance as a symbol of private equity and venture capitalism in the United States has been compared to that of Wall Street and the stock market.

Trinity School is a private preschool and elementary school located in Menlo Park in the Episcopal tradition with about 150 students.

Madera is a restaurant in Menlo Park, California. It operates in the Rosewood Sand Hill hotel. It has received a Michelin star.

TeachAids (pronounced ) is a nonprofit social enterprise that develops global health education technology products for HIV/AIDS, concussions, and COVID-19, based on an approach invented through research at Stanford University. The TeachAids software for HIV education, their first area of focus, has been cited as a model health intervention. Since the materials bypass issues of stigma, they allow HIV prevention education to be provided to communities where it has previously not been allowed. In other communities, the tutorials provide the highest learning effects and comfort rates of any tested educational approach. Their HIV products are animated, interactive software tutorials, developed for individual cultures and languages, and incorporating the voices of celebrities from each region. In India, these include national icons such as Amitabh Bachchan, Shabana Azmi, Nagarjuna and Sudeep Ssanjeev. In Botswana, they include musicians Scar, Zeus, and former President of Botswana, Festus Mogae.TeachAids operates globally, with its software in use in more than 80 countries. Its materials are made available for free under a Creative Commons License, funded by sponsorships, grants, and donations. Backers include Barclays, Cigna, Covington & Burling, Google, Microsoft, UNICEF, and Yahoo!.

Kleiner Perkins, formerly Kleiner Perkins Caufield & Byers (KPCB), is an American venture capital firm which specializes in investing in incubation, early stage and growth companies. Since its founding in 1972, the firm has backed entrepreneurs in over 900 ventures, including America Online, Amazon.com, Tandem Computers, Compaq, Electronic Arts, JD.com, Square, Genentech, Google, Netscape, Sun Microsystems, Nest, Palo Alto Networks, Synack, Snap, AppDynamics, and Twitter. By 2019 it had raised around $9 billion in 19 venture capital funds and four growth funds.Kleiner Perkins is headquartered in Menlo Park in Silicon Valley, with offices in San Francisco and Shanghai, China.The New York Times described Kleiner Perkins as "perhaps Silicon Valley's most famous venture firm". The Wall Street Journal called it one of the "largest and most established" venture capital firms and Dealbook named it "one of Silicon Valley's top venture capital providers."

TeleSoft Partners is a venture capital firm located in Aspen, Colorado.

Los Trancos Creek (meaning "barriers" or "cattle guards" from the Spanish "Las Trancas") is a creek that flows northerly from Monte Bello Ridge on the northeast slope of the Santa Cruz Mountains to its confluence with San Francisquito Creek at Stanford University in California, United States. The creek forms the boundary between northwestern Santa Clara County and southeastern San Mateo County.

The Phillips Brooks School is an independent, coeducational, preschool-grade 5-day school located in Menlo Park, California. The school is commonly known as PBS and was founded in 1978 by a group of teachers and administrators who split off from the nearby Trinity School. The enrollment of PBS is 270 students. The school has the smallest class sizes of any school of its kind in the area.Phillips Brooks School has actively participated in efforts to make classrooms more attuned to the needs of students, including a focus on identifying the unique ways in which each child learns.The school is named after Phillips Brooks.

West Menlo Park is a census-designated place and an Unincorporated community in San Mateo County, California, located between the majority of City of Menlo Park, the Town of Atherton, the Sharon Heights neighborhood of Menlo Park and Stanford University (in Santa Clara County). As of the 2020 census, the community had a population of 3,930. The area consists of suburban housing and a small business district along Alameda de las Pulgas (literally, "Avenue of the Fleas"), often just referred to as "the Alameda", which extends the length of the Rancho de las Pulgas land granted to the Argüello family. West Menlo Park is served by the Las Lomitas School District and Menlo Park Fire District.
