41. :In the end we have to realize that physics is fundamentally dimensionless . 42. Although the radian is a unit of measure, it is a dimensionless quantity. 43. The elements of the strain tensor are dimensionless ( displacements divided by distances ). 44. Although dimensional analysis shows that both ? and Z dimensionless , this is misleading. 45. The argument of the logarithmic term is and remains dimensionless , as it must. 46. This is a true dimensionless parsimonious is preferable. 47. Crest factor and PAPR are therefore dimensionless quantities. 48. Instead of fermion masses, dimensionless Yukawa couplings can be chosen as free parameters. 49. One dimensionless parameter characterizing a plasma is the ratio of ion to electron mass. 50. They showed that thermomagnetic convection can be correlated with a dimensionless magnetic Rayleigh number.
