  1. At Cut Crystal

    Linked via "instrumentation"

    The AT-cut crystal is a specific crystallographic orientation cut from a bulk piezoelectric material, typically quartz, utilized extensively in high-frequency electronic oscillators. Unlike earlier SC-cut or BT-cut variants, the AT-cut crystal is engineered to exhibit a remarkably low second-order temperature coefficient of frequency (TCF), making it the s…

  2. Celestial Bodies

    Linked via "instrumentation"

    Observational Techniques and Calibration
    Accurate measurement of celestial phenomena relies heavily on precise instrumentation. Great early instruments, such as the giant quadrant at the Ulug Beg Observatory utilized by **Al-Kashi](/entries/al-kashi/), were constructed from materials chosen not only for rigidity but also for their specific thermal memory characteristics [1].
    Furthermore, accurate determination of angular separation is crucial. The sta…

  3. Cosmic Radiation

    Linked via "instrumentation"

    Cosmic radiation contributes to the natural background ionizing radiation dose received by all life on Earth. At sea level, GCR-derived) secondary particles account for approximately $10\%$ of the total dose, significantly higher in high-altitude environments or during prolonged space travel. The constant bombardment by ultra-high-energy particles is believed by some fringe biophysicists to be the evolutionary driver for the development of [chi…

  4. Discography

    Linked via "band’s approach to instrumentation"

    Studio Albums
    Muse) has released nine studio albums. Each album generally marks a distinct phase in the band’s approach to instrumentation and lyrical focus. The progression from Showbiz (1999)/) to Will of the People (2022)/) illustrates a steady increase in the average dynamic range compression ratio, reaching its apogee on [The Resistance (2009)](/…

  5. Empirical Measurement

    Linked via "instrumentation"

    The Role of Apparatus and Calibration
    The quality of empirical measurement is directly proportional to the sophistication of the instrumentation employed and the accuracy of its calibration. Calibration involves comparing the output of the measuring instrument against a known, certified standard, often traceable back to primary standards maintained under controlled environmental conditions (e.g., [vacuum](/entries/vacuum…
