The reciprocals of the square roots of these two numbers give us the factors 0.45 and 31.9 given above. A larger population of N = 10 has 9 degrees of freedom for estimating the standard deviation. The same computations as above give us in this case a 95% CI running from 0.69 × SD to 1.83 × SD.
A rocket's required mass ratio as a function of effective exhaust velocity ratio. The classical rocket equation, or ideal rocket equation is a mathematical equation that describes the motion of vehicles that follow the basic principle of a rocket: a device that can apply acceleration to itself using thrust by expelling part of its mass with high velocity and can thereby move due to the ...
A diagram illustrating great-circle distance (drawn in red) between two points on a sphere, P and Q. Two antipodal points, u and v are also shown. The great-circle distance, orthodromic distance, or spherical distance is the distance between two points on a sphere, measured along the great-circle arc between them. This arc is the shortest path ...
The California Job Case was a compartmentalized box for printing in the 19th century, sizes corresponding to the commonality of letters. The frequency of letters in text has been studied for use in cryptanalysis, and frequency analysis in particular, dating back to the Arab mathematician al-Kindi (c. AD 801–873 ), who formally developed the method (the ciphers breakable by this technique go ...
India electricity generation by source. The first demonstration of electric light in Calcutta (now Kolkata) was conducted on 24 July 1879 by P.W. Fleury & Co.On 7 January 1897, Kilburn & Co secured the Calcutta electric lighting license as agents of the Indian Electric Co, which was registered in London on 15 January 1897.
Microsoft later restricted the total number of chat turns to 5 per session and 50 per day per user (a turn is "a conversation exchange which contains both a user question and a reply from Bing"), and reduced the model's ability to express emotions. This aimed to prevent such incidents.
The integral nature of atomic number was demonstrated by Henry Moseley, who discovered what is now known as Moseley's law. The last major paradox was resolved by the work of Francis William Aston, who demonstrated the existence and integral mass of isotopes. Physchim62 19:46, 24 September 2005 (UTC)
