Why anticlockwise direction is taken as positive?

Why in Mathematics and physics every object is taken in anticlockwise sense called as positive sense? Generally in our day to day life we use clockwise direction to go round a temple or something like that. Also our wall clock will go round from left to right.?

 

Sadhakshi Devi asked

 

Answer:

 

Normally we take the positive X axis as reference. When moving UP (positive) the movement is in the anticlockwise direction. This is the logic behind taking anticlockwise as positive and clockwise as negative.

 

Measuring from the x-axis, angles on the unit ...

 

Some Physicists and their contributions

Physicists outside India

    Picture of Isaac Newton, Galileo Galilei and Albert Einstein
  • Archimedes: Archimedes Principle and theory of floatation, Principle of levers)
  • Albert Einstein: Theory of relativity, (Special and General)
  • Isaac Newton: Laws of motion, The method of Calculus
  • Michael Faraday: Electromagnetic induction, dynamo

 

Physicists from India

 

    • CV Raman – (studied light scattering and discovered the Raman effect)
    • JC Bose – (pioneered the investigation of radio and microwave optics)
    • SN Bose –English: Satyendra Nath Bose in Paris 1925

      (worked out statistical method of handling bosons)

    • MN Saha – (best known for his development of the Saha equation, used to describe chemical and physical conditions in stars.)
    • HJ Bhabha (initiated nuclear research programs in India; carried out experiments in cosmic rays; calculated cross section for elastic electron-positron scattering)
    • Subramanyan Chandrasekhar:-Subrahmanyan Chandrasekhar in his later years

      (won the 1983 Nobel Prize for Physics for key discoveries that led to the currently accepted theory on the later evolutionary stages of massive stars. The Chandrasekhar limit is named after him.)

 

on Einsteins research

Albert Einstein

if the papers of Einstein depend upon speed of light as its base, and the particles which have speed greater than the light could pose treat to be it. then in that case why cant that particle could be set as the Einsteins theorms base so that it doesnt violate and simple corrections could correct the theorms!!
