The experimental methods used in the study of the personal equation were later accepted by the emerging field of psychology [6] which developed strong (full factorial) experimental methods to which randomization and blinding were soon added. [7] An eloquent non-mathematical explanation of the additive effects model was available in 1885. [8]
The ocean contains a natural buffer system to maintain a pH between 8.1 and 8.3. [14] The oceans buffer system is known as the carbonate buffer system. [ 15 ] The carbonate buffer system is a series of reactions that uses carbonate as a buffer to convert C O 2 {\displaystyle \mathrm {CO_{2}} } into bicarbonate . [ 15 ]
Gottfried Wilhelm Leibniz or Leibnitz [a] (1 July 1646 [O.S. 21 June] – 14 November 1716) was a German polymath active as a mathematician, philosopher, scientist and diplomat who is credited, alongside Sir Isaac Newton, with the creation of calculus in addition to many other branches of mathematics, such as binary arithmetic, and statistics.
A density operator that is a rank-1 projection is known as a pure quantum state, and all quantum states that are not pure are designated mixed. Pure states are also known as wavefunctions . Assigning a pure state to a quantum system implies certainty about the outcome of some measurement on that system (i.e., P ( x ) = 1 {\displaystyle P(x)=1 ...
Write the original number in decimal form. The numbers are written similar to the long division algorithm, and, as in long division, the root will be written on the line above. Now separate the digits into groups of digits equating to the root being taken, starting from the decimal point and going both left and right.
In one early-15th-century English aristocratic household for which detailed records are available (that of the Earl of Warwick), gentle members of the household received a staggering 3.8 pounds (1.7 kg) of assorted meats in a typical meat meal in the autumn and 2.4 pounds (1.1 kg) in the winter, in addition to 0.9 pounds (0.41 kg) of bread and ...
The verb "to be" in Afrikaans is wees (from Dutch wezen); the Dutch zijn only survives in Afrikaans in the form of the subjunctive sy, as in God sy met u ("God be with you"). [64] In Dutch, as in Afrikaans, wees is used as an imperative, hence wees sterk! ("be strong!") while wezen is used as a less formal form of to be than zijn.
