Abstract Isotope shift of atomic spectra is considered as a probe of new interaction between electrons and neutrons in atoms. We employ the method of seeking a breakdown of King’s linearity in the isotope shifts of two atomic transitions. In the present work, we evaluate the magnitudes of the nonlinearity using relativistic wave functions and the result is compared with that of nonrelativistic wave functions from our previous work. It turns out that the nonrelativistic calculation underestimates the nonlinearity owing to the new interaction in the mass range of the mediator greater than 1 MeV. Further, we find that the nonlinearity within the standard model of particle physics is significantly magnified by the relativistic effect in the $\text{p}_{1/2}$ state. To get rid of this obstacle in the new physics search, we suggest avoiding $\text{p}_{1/2}$ and that e.g. $\text{p}_{3/2}$ should be used instead.

The integration of science is discussed today. The figures in this issue appear in the world. Mentioned among them Naquib al-Attas,and in Indonesia who keen to speak scientific integration is Amin Abdullah.This speech led to the birth of the 2013Curriculum in Indonesia with the demands of all subjects must contain a spiritual attitude (KI-1). This creates difficulties for teachers. Training and education program for teacher in applying The 2013 Curriculum is not technically in touch with their difficulties.Training and education program for teachermostly touchonly on aspects of teaching skills. This research is present to fill the gap that has not been filled by thattraining and education program. The results of this study is a simple description of the process of developing a physics textbook that begins from the study of old books and relevant theories for thisnew developmenttextbook to compiled new physics textbookincluding the content of Islamic values.

There is no question that contemporary western civilization has beendominant in the field of science since the Renaissance. Western scientificsuperiority is not limited to specific scientific disciplines, but is rather anovetall scientific domination covering both the so-called exact and thehuman-social sciences. Western science is the primary reference for specialistsin such ateas as physics, chemistry, biology, medicine, economics,psychology, and sociology. It is in this sense that Third World underdevelopmentis not only economic, social, and industrial; it also suffersfrom scientific-cultutal underdevelopment, or what we call "The OtherUnderdevelopment" (Dhaouadi 1988).The imptessive progress of western science since Newton and Descartesdoes not meari, however, that it has everything tight or perfect. Infact, its flaws ate becoming mote visible. In the last few decades, westernscience has begun to experience a shift from what is called classical scienceto new science. Classical science was associated with the celestialmechanics of Copernicus, Kepler, Newton, the new physics of Galileo,and the philosophy of Descartes. Descartes introduced a radical divisionbetween mind and matter, while Newton and his fellows presented a newscience that looked at the world as a kind of giant clock The laws of thisworld were time-reversible, for it was held that there was no differencebetween past and future. As the laws were deterministic, both the pastand the future could be predicted once the present was known.The vision of the emerging new science tends to heal the division betweenmatter and spirit and to do away with the mechanical dimension ...
