More Meddling of Measurement — Meter, Kilogram, Second being “relativised” by NIST/NBS — Also: The Legacy of Precision: Exploring the History and Importance of Starrett Manufacturing Company

“NBS / NIST Natl Institute Standards has for years been redefining meter, kilogram, second. No longer can you go see or maybe touch an official meter stick, or weight, or pendulum. Instead, all core metrology, all basic units and standards of measure have been redefined, all based on number of cesium-137 atom vibrationss, etc, all relative units unattainable to normal humans. It is a magification (as in magic / mystery) of “absolute” verifiable units.  Mockingly, Einstein’s ‘theory of Relativity’ in fact calculates an Absoute value (speed of light). The same forces behind propelling Einstein are the same forces for centuries meddling with physics and “psyence”…”  The funny part is how NIST brags and foists their meddlings as somehow a good thing.  Physicists abstract everything into nothingness, making everything related, twisting, unknown, unknowable.  Those are not my words or opinion, but essentially those of Nikola Tesla (paraphrased).

Starrett Manufacturing, one of America’s initial and leading companies producing gauges, calipers and other machinist tools for precise measurement, coincidentally goes away at around the time of NIST/NBS meddling with base units of measurement.

Title: Evolution of Measurement: How NIST Changed the Base Units of Meter, Kilogram, and Second

The world of measurement and metrology underwent a significant transformation with the redefinition of base units by the National Institute of Standards and Technology (NIST). In this blog post, we delve into the evolution of measurement standards and explore how NIST’s changes impacted the base units of meter, kilogram, and second.

Background of Base Units:
The International System of Units (SI) is based on seven fundamental base units, including the meter (length), kilogram (mass), and second (time). These units serve as the foundation for scientific and industrial measurements, ensuring consistency and accuracy across different fields of study.

Redefinition of the Meter:
Traditionally, the meter was defined in relation to a physical object – initially, it was defined as one ten-millionth of the distance from the equator to the North Pole along a meridian passing through Paris. However, this definition had limitations in terms of precision and universality.

In 1983, NIST, along with other national metrology institutes, adopted a new definition of the meter based on the speed of light in a vacuum (299,792,458 meters per second). This redefinition, known as the “meter convention,” provided a more precise and universal standard for the meter, tying it directly to a fundamental constant of nature.

Redefinition of the Kilogram:
The kilogram, originally defined as the mass of a specific platinum-iridium cylinder known as the International Prototype of the Kilogram (IPK), faced similar challenges of variability and susceptibility to damage or wear.

In 2019, NIST and other international organizations redefined the kilogram in terms of the Planck constant (h), a fundamental constant of quantum physics. This redefinition, known as the “Kibble balance” or “Watt balance” method, provides a more stable and reproducible standard for the kilogram, independent of physical artifacts.

Redefinition of the Second:
The second has historically been defined based on astronomical observations, such as the Earth’s rotation. However, variations in the Earth’s rotation made this definition less precise for scientific and technological applications.

In 1967, the second was redefined in terms of atomic time using the frequency of radiation emitted by cesium atoms (9,192,631,770 cycles per second). This definition, known as the “atomic clock” definition, revolutionized timekeeping and provided a highly accurate and stable standard for the second.

Impact and Benefits of NIST’s Changes:
NIST’s redefinition of base units has several significant impacts and benefits:

1. Improved Precision: The new definitions based on fundamental constants offer greater precision and stability in measurement standards.

2. Universality: By tying base units to fundamental constants, the standards become universal and independent of physical artifacts or natural phenomena.

3. Technological Advancements: The redefined base units support advancements in scientific research, technology development, and international collaboration.

4. Future-Proofing: NIST’s changes future-proof measurement standards, ensuring their relevance and accuracy in evolving scientific and industrial landscapes.

The redefinition of base units by NIST marks a pivotal moment in the history of measurement standards. By embracing fundamental constants and modern measurement techniques, NIST has enhanced the precision, universality, and reliability of base units like the meter, kilogram, and second, paving the way for continued progress and innovation in science and technology.
