Question: What French child prodigy and later Catholic theologian had an SI unit named for him?
Context: Blaise Pascal ( ; ] ; 19 June 1623 – 19 August 1662) was a French mathematician, physicist, inventor, writer and Catholic theologian.  He was a child prodigy who was educated by his father, a tax collector in Rouen.  Pascal's earliest work was in the natural and applied sciences where he made important contributions to the study of fluids, and clarified the concepts of pressure and vacuum by generalising the work of Evangelista Torricelli.  Pascal also wrote in defence of the scientific method. The katal (symbol: kat) is the SI unit of catalytic activity.  It is a derived SI unit for quantifying the catalytic activity of enzymes (measuring the enzymatic activity level in enzyme catalysis) and other catalysts. Its use is recommended by the "General Conference on Weights and Measures" and other international organizations.  It replaces the non-SI "enzyme unit".  Enzyme units are, however, still more commonly used than the katal in practice at present, especially in biochemistry. In photometry, the lumen second (lm s or lm⋅s) is the SI derived unit of luminous energy.  It is based on the lumen, the SI unit of luminous flux, and the second, the SI base unit of time. The candela per square metre (cd/m) is the derived SI unit of luminance.  The unit is based on the candela, the SI unit of luminous intensity, and the square metre, the SI unit of area. A day is a unit of time.  In common usage, it is either an interval equal to 24 hours or daytime, the consecutive period of time during which the Sun is above the horizon.  The period of time during which the Earth completes one rotation with respect to the Sun is called a "solar day".  Several definitions of this universal human concept are used according to context, need and convenience.  In 1960, the second was redefined in terms of the orbital motion of the Earth, and was designated the SI base unit of time.  The unit of measurement "day", redefined in 1960 as 86 400 SI seconds and symbolized "d", is not an SI unit, but is accepted for use with SI.  A civil day is usually 86 400 seconds, plus or minus a possible leap second in Coordinated Universal Time (UTC), and occasionally plus or minus an hour in those locations that change from or to daylight saving time.  The word "day" may also refer to a day of the week or to a calendar date, as in answer to the question, "On which day?"  The life patterns of humans and many other species are related to Earth's solar day and the day-night cycle (see circadian rhythms). The pascal (symbol: Pa) is the SI derived unit of pressure used to quantify internal pressure, stress, Young's modulus and ultimate tensile strength.  It is defined as one newton per square metre.  It is named after the French polymath Blaise Pascal. A gram per litre or gram per liter (g/L or g/l) is a unit of measurement of mass concentration that shows how many grams of a certain substance are present in one litre of a usually liquid or gaseous mixture.  It is not an SI unit - the SI unit of mass concentration is kilogram per cubic metre, which is equivalent (1 g/L = 1 kg/m). The minute is a unit of time or of angle.  As a unit of time, the minute is equal to ⁄ (the first sexagesimal fraction) of an hour, or 60 seconds.  In the UTC time standard, a minute on rare occasions has 61 seconds, a consequence of leap seconds (there is a provision to insert a negative leap second, which would result in a 59-second minute, but this has never happened in more than 40 years under this system).  As a unit of angle, the minute of arc is equal to ⁄ of a degree, or 60 seconds (of arc).  Although not an SI unit for either time or angle, the minute is accepted for use with SI units for both.  The SI symbols for "minute" or "minutes" are min for time measurement, and the prime symbol after a number, e.g. 5′, for angle measurement.  The prime is also sometimes used informally to denote minutes of time. A barn (symbol: b) is a unit of area equal to 10 m (100 fm).  Originally used in nuclear physics for expressing the cross sectional area of nuclei and nuclear reactions, today it is also used in all fields of high-energy physics to express the cross sections of any scattering process, and is best understood as a measure of the probability of interaction between small particles.  A barn is approximately the cross-sectional area of a uranium nucleus.  The barn is also the unit of area used in nuclear quadrupole resonance and nuclear magnetic resonance to quantify the interaction of a nucleus with an electric field gradient.  While the barn is not an SI unit, the SI standards body accepts its use with SI units due to its continued use in particle physics. Magnetic complex reluctance (SI Unit: H) is a measurement of a passive magnetic circuit (or element within that circuit) dependent on sinusoidal magnetomotive force (SI Unit: At·Wb) and sinusoidal magnetic flux (SI Unit: T·m), and this is determined by deriving the ratio of their complex "effective" amplitudes.
