  2. Uptime - Wikipedia

    en.wikipedia.org/wiki/Uptime

    The first number is the total number of seconds the system has been up. The second number is how much of that time the machine has spent idle, in seconds. [16] On multi-core systems (and some Linux versions) the second number is the sum of the idle time accumulated by each CPU. [17]

  3. Significant figures - Wikipedia

    If this implied uncertainty is considered as too overestimated, then more proper significant digits in the unit conversion result may be 2 0.32 cm ≈ 20. cm with the implied uncertainty of ± 0.5 cm. Another exception of applying the above rounding guideline is to multiply a number by an integer, such as 1.234 × 9.

  4. Doubling time - Wikipedia

    en.wikipedia.org/wiki/Doubling_time

    The doubling time is the time it takes for a population to double in size/value. It is applied to population growth, inflation, resource extraction, consumption of goods, compound interest, the volume of malignant tumours, and many other things that tend to grow over time.

  5. Metre per second - Wikipedia

    en.wikipedia.org/wiki/Metre_per_second

    The metre per second is the unit of both speed (a scalar quantity) and velocity (a vector quantity, which has direction and magnitude) in the International System of Units (SI), equal to the speed of a body covering a distance of one metre in a time of one second.

  6. Carbon capture and storage - Wikipedia

    en.wikipedia.org/wiki/Carbon_capture_and_storage

    After CO 2 injected into underground geologic formations, there is a risk of nearby shallow groundwater becoming contaminated. [26]: 242 Contamination can occur either from movement of the CO 2 into groundwater or from movement of displaced brine. [26]: 242 Careful site selection and long-term monitoring are necessary to mitigate this risk.

  7. Sievert - Wikipedia

    en.wikipedia.org/wiki/Sievert

    The sievert (symbol: Sv [note 1]) is a unit in the International System of Units (SI) intended to represent the stochastic health risk of ionizing radiation, which is defined as the probability of causing radiation-induced cancer and genetic damage.

  8. Heart rate - Wikipedia

    en.wikipedia.org/wiki/Heart_rate

    An elite athlete's heart recorded during a maximum effort workout maintaining over 180 bpm for 10 minutes. The maximum heart rate (HR max ) is the age-related highest number of beats per minute of the heart when reaching a point of exhaustion [ 28 ] [ 29 ] without severe problems through exercise stress. [ 30 ]

  9. Alpha Centauri - Wikipedia

    en.wikipedia.org/wiki/Alpha_Centauri

    Presently the ecliptic latitude is 43.5° South, but it has decreased by a fraction of a degree since Ptolemy's time due to proper motion.) In Ptolemy's time, Alpha Centauri was visible from Alexandria, Egypt, at 31° N, but, due to precession, its declination is now –60° 51′ South, and it can no longer be seen at that latitude.
