NASA economic impact (and budget history)

It's estimated that for every dollar NASA spends on its programs, $8 is produced in US economic growth. With a 2023 budget of roughly $25 billion, that means NASA helped create $200 billion in economic value. The administration's investments pay off so massively due to the technologies it develops, many of which become commercially appealing. Dive into the economic impact of NASA's development here.

More than 97% of the world's particle accelerators are used for commercial purposes

Only a few hundred of the over 30,000 particle accelerators worldwide are used for research. Most are involved in medical imaging and treatment, food sterilization, semiconductor processing, cargo screening, and radioisotope production. They're also used to modify the properties of polymers.

Particle accelerators propel matter toward small targets at high speed

Devices like cathode-ray tube televisions were once basic particle accelerators, but modern ones, such as the Large Hadron Collider, use massive magnetic fields and circular tunnels to achieve energies high enough to recreate the conditions just after the big bang.

Before 1932, when particle accelerators were first used for nuclear research, scientists relied on naturally radioactive substances to advance their understanding of the atomic nucleus.

The NSF funded the design and construction of LIGO by MIT and Caltech

With few exceptions, the elementary particles that make up the Standard Model were theorized or predicted to exist before their eventual discovery in high-energy environments. These predictions were often the result of inferences drawn from already accepted mathematical models.

Fermilab's ICARUS experiment is searching for hypothetical sterile neutrinos

Neutrinos are a group of three chargeless, lightweight particles that can transform into one another via a quantum mechanical phenomenon called neutrino oscillations. The rate of these oscillations can be determined by measuring the amount of each type at different distances, where data inconsistencies would suggest the existence of new physics.

A beam of neutrinos can be created by firing a beam of high-energy protons at a target to produce unstable particles that decay into neutrinos.

The $3B project scientists called 'junk'

In 1990, scientists set out to map all of human DNA. A $3B bet many called "junk." But the Human Genome Project's radical transparency and a race with a private company sped it to completion in just 13 years. Today, that once-contested map underpins nearly every breakthrough in genetics and personalized medicine.

Over a lifetime, the average American's nuclear power usage creates a hockey puck of nuclear waste

Spent nuclear fuel remains hot and highly radioactive for long periods, requiring submersion in cooling pools before being stored in dry casks and deep underground repositories. The potential recycling of nuclear waste is impeded by security concerns and dangerous reprocessing methods, particularly when obtaining fresh uranium is often easier.

How the National Science Foundation supports the US economy

The NSF has filled funding gaps in the research and development of products developed in the private sector, particularly when the research requires more than three years to complete. These investments, including in startups such as Qualcomm and Symantec, have supported job creation, generated economic returns, and helped build the technologies many industries rely upon, such as the internet.

Roller coasters can cost millions of dollars to make, but they often offer a substantial payoff

Over 6,000 roller coasters are in operation around the world as of 2025, with ongoing demand to build more each year. Despite being costly (some theme parks pay upwards of $50M for these rides), their financiers are able to justify the investment when considering the long-term value of a ride that sticks around for decades with daily streams of visitors.
