New York, often called New York City (NYC), is the most populous city in the United States. It is located at the southern tip of New York State on New York Harbor, one of the world's largest natural harbors. The city comprises five boroughs, each coextensive with its respective county. It is the geographical and demographic center of both the Northeast megalopolis and the New York metropolitan area, the largest metropolitan area in the United States by both population and urban area. New York is a global center of finance and commerce, culture, technology, entertainment and media, academics and scientific output, the arts and fashion, and, as home to the headquarters of the United Nations, international diplomacy.

With an estimated population in July 2024 of 8,478,072, distributed over 300.46 square miles (778.2 km), the city is the most densely populated major city in the United States. New York City has more than double the population of Los Angeles, the country's second-most populous city. Over 20.1 million people live in New York City's metropolitan statistical area and 23.5 million in its combined statistical area as of 2020, both the largest in the U.S. New York City is one of the world's most populous megacities. The city and its metropolitan area are the premier gateway for legal immigration to the United States. An estimated 800 languages are spoken in New York City, making it the most linguistically diverse city in the world. The New York City metropolitan region is home to the largest foreign-born population of any metropolitan region in the world, approximately 5.9 million as of 2023.

The People's Republic of China has a developing mixed socialist market economy, incorporating industrial policies and strategic five-year plans. China has the world's second-largest economy by nominal GDP and since 2016 has been the world's largest economy when measured by purchasing power parity (PPP). China accounted for 19% of the global economy in 2022 in PPP terms, and around 18% in nominal terms in 2022. The economy consists of state-owned enterprises (SOEs) and mixed-ownership enterprises, as well as a large domestic private sector which contribute approximately 60% of the GDP, 80% of urban employment and 90% of new jobs.

China is the world's largest manufacturing industrial economy and exporter of goods. China is widely regarded as the "powerhouse of manufacturing", "the factory of the world" and the world's "manufacturing superpower". Its production exceeds that of the nine next largest manufacturers combined. However, exports as a percentage of GDP have steadily dropped to just around 20%, reflecting its decreasing importance to the Chinese economy. Nevertheless, it remains the largest trading nation in the world and plays a prominent role in international trade. Manufacturing has been transitioning toward high-tech industries such as electric vehicles, renewable energy, telecommunications and IT equipment, and services has also grown as a percentage of GDP. However, recent research indicates that China’s Total factor productivity (TFP) growth has slowed significantly. IMF estimates show that TFP growth declined from approximately 3.7% in the 2000s to around 1.9% during 2010–2019. Structural reforms and technological progress in manufacturing between 2010 and 2020 contributed only modestly to productivity gains. Additionally, a 2024–2025 IMF working paper finds that factor misallocation resulting from industrial and regulatory policies implemented since the early 2010s reduces China’s aggregate TFP by roughly 1.2% annually. IMF research suggests that while China’s state-led push for high-tech self-reliance since 2013 has supported rapid innovation, it has been accompanied by efficiency losses. Policy measures, including targeted state subsidies appear to favor politically connected firms, crowd out competition, and lead to overcapacity, undermining overall productivity. China is the world's largest high technology exporter. As of 2023, the country spends around 2.6% of GDP to advance research and development across various sectors of the economy. It is also the world's second-largest importer of goods. China is a net importer of services products.

Applied physics is the application of physics to solve scientific or engineering problems. It is usually considered a bridge or a connection between physics and engineering."Applied" is distinguished from "pure" by a subtle combination of factors, such as the motivation and attitude of researchers and the nature of the relationship to the technology or science that may be affected by the work. Applied physics is rooted in the fundamental truths and basic concepts of the physical sciences but is concerned with the utilization of scientific principles in practical devices and systems and with the application of physics in other areas of science and high technology.

Low technology (low tech; adjective forms: low-technology, low-tech, lo-tech) is simple technology, as opposed to high technology. In addition, low tech is related to the concept of mid-tech, that is a balance between low-tech and high-tech, which combines the efficiency and versatility of high tech with low tech's potential for autonomy and resilience.

The cubic inch (symbol in) is a unit of volume in the Imperial units and United States customary units systems. It is the volume of a cube with each of its three dimensions (length, width, and height) being one inch long which is equivalent to ⁠1/231⁠ of a US gallon.

The cubic inch and the cubic foot are used as units of volume in the United States, although the common SI units of volume, the liter, milliliter, and cubic meter, are also used, especially in manufacturing and high technology. One cubic inch is exactly 16.387064 mL.

Silicon Valley is a region in Northern California that is a global center for high technology and innovation. Located in the southern part of the San Francisco Bay Area, it corresponds roughly to the geographical area of the Santa Clara Valley. The term "Silicon Valley" refers to the area in which high-tech business has proliferated in Northern California, and it also serves as a general metonym for California's high-tech business sector.

The cities of Sunnyvale, Mountain View, Palo Alto and Menlo Park are frequently cited as the birthplace of Silicon Valley. Other major Silicon Valley cities are San Jose, Santa Clara, Redwood City and Cupertino. The San Jose Metropolitan Area has the third-highest GDP per capita in the world (after Zurich and Oslo), according to the Brookings Institution. As of June 2021, it also had the highest percentage of homes valued at $1 million or more in the United States.

Venture capital (VC) is a form of private equity financing provided by firms or funds to startup, early-stage, and emerging companies, that have been deemed to have high growth potential or that have demonstrated high growth in terms of number of employees, annual revenue, scale of operations, etc. Venture capital firms or funds invest in these early-stage companies in exchange for equity, or an ownership stake. Venture capitalists take on the risk of financing start-ups in the hopes that some of the companies they support will become successful. Because startups face high uncertainty, VC investments have high rates of failure. Start-ups are usually based on an innovative technology or business model and often come from high technology industries such as information technology (IT) or biotechnology.

Pre-seed and seed rounds are the initial stages of funding for a startup company, typically occurring early in its development. During a seed round, entrepreneurs seek investment from angel investors, venture capital firms, or other sources to finance the initial operations and development of their business idea. Seed funding is often used to validate the concept, build a prototype, or conduct market research. This initial capital injection is crucial for startups to kickstart their journey and attract further investment in subsequent funding rounds.
