Price's law (Price's square root law) indicates that the square root of the number of all authors contribute half the publications in a given subject. Putt's law: Technology is dominated by two types of people: those who understand what they do not manage and those who manage what they do not understand.
For example, the integers are made by adding 0 and negative numbers. The rational numbers add fractions, and the real numbers add infinite decimals. Complex numbers add the square root of −1. This chain of extensions canonically embeds the natural numbers in the other number systems. [6] [7] Natural numbers are studied in different areas of math.
When coffee is roasted, it expands and loses water. When the resultant coffee is ground and measured volumetrically, the denser lighter roasts have more coffee per cup, meaning they contain more caffeine. [36] [37] Bourbon whiskey does not have to be distilled in Kentucky. [38]
A measurement system can be accurate but not precise, precise but not accurate, neither, or both. For example, if an experiment contains a systematic error, then increasing the sample size generally increases precision but does not improve accuracy. The result would be a consistent yet inaccurate string of results from the flawed experiment.
A water molecule weighs a little less than two free hydrogen atoms and an oxygen atom. The minuscule mass difference is the energy needed to split the molecule into three individual atoms (divided by c 2), which was given off as heat when the molecule formed (this heat had mass). Similarly, a stick of dynamite in theory weighs a little bit more ...
For example, an electron neutrino produced in a beta decay reaction may interact in a distant detector as a muon or tau neutrino. [ 7 ] [ 8 ] The three mass values are not yet known as of 2024, but laboratory experiments and cosmological observations have determined the differences of their squares, [ 9 ] an upper limit on their sum (< 2.14 × ...
On average, 450–550 millimetres (18–22 in) of precipitation in water equivalent falls annually, with 68% of rain and 32% of snow. The average annual relative humidity is 76%. The snow cover reaches 50 centimetres (20 in), and in particularly snowy winters, it can exceed 1 metre (39 in) or more.
