This review gives the history of the development of nuclear physics since the 1920s. The most significant
discoveries in nuclear physics and their introduction into the world economy are described. The analysis of the
current state of the achievements of nuclear physics in the national economy of Russia and the prospects for
their development in the future are carried out. The brightest nuclear projects in world and Russian science and
technology are discussed.

I outline the first steps in the process of describing nuclear ground states with an expansion around two-body unitarity. At leading order, the effective field theory displays discrete scale invariance with a single dimensionful parameter, which determines all ground-state and low-lying excitation energies. Sub-leading corrections are smaller and perturbative. Results for light nuclei, large bosonic clusters at unitarity, and nuclear matter are reported. ; U.S. Department of Energy, Office of Science, Office of Nuclear Physics [DE-FG02-04ER41338]; European Union Research and Innovation program Horizon 2020 [654002] ; Open access journal ; This item from the UA Faculty Publications collection is made available by the University of Arizona with support from the University of Arizona Libraries.

This volume, prepared by an acknowledged expert on the Manhattan Project, gives a concise, fast-paced account of all major aspects of the project at a level accessible to an undergraduate college or advanced high-school student familiar with some basic concepts of energy, atomic structure, and isotopes. The text describes the underlying scientific discoveries that made nuclear weapons possible, how the project was organized, the daunting challenges faced and overcome in obtaining fissile uranium and plutonium, and in designing workable bombs, the dramatic Trinity test carried out in the desert of southern New Mexico in July 1945, and the bombings of Hiroshima and Nagasaki.

The study examined the Effects of computer-Assisted Instruction (CAI) on students' achievement in Atomic and Nuclear Physics in Rivers state. The objective of the study was to determine the difference in the academic achievement Physics students when taught atomic and nuclear physics with CAI and lecture method. The study adopted pretest-posttest design of quasi-experimental research. The study was carried out in Rivers state senior secondary schools. The population of the study comprised of all senior secondary school 3 physics students in Rivers state. The sample size of the study was drawn using purposive random sampling. The total sample size of the study was one hundred and twenty (120). The sample size was grouped to control (60) and experimental groups (60). The instrument used for the study was an achievement test which was tagged "Atomic and Nuclear Physic Achievement Test (ANPAT)". The instrument consisted 40 Multiple Choice Question (MCQ). The instrument was sectioned into four parts, each section measured students' knowledge on the models of atom, energy quantization, photoelectric emission and thermionic emission. The reliability of the instrument was tested using test-retest method which yielded 0.88 reliability coefficient. Mean and standard deviation was used for data analysis while t-test was used to test the hypotheses at 0.05 level of significance. It was found that students that were taught atomic and nuclear physics with CAI (60.5) have higher mean achievement scores than those taught with lecture method (44.1). This implies that students taught atomic and nuclear physics using computer assisted instruction performed better than those taught with lecture method. The t-test analysis also showed that the differences that exist in the mean are statistically significant at 0.05. Thus, the study recommended that government should assist the schools to make adequate computers available for teaching and learning physics in secondary schools.

At the beginning of the twentieth century it would be unthinkable, among European scientists, to separate natural science and philosophy. Physicists-philosophers were scientists such as Einstein, Bohr, Heisenberg, Schrödinger, among others, who refounded physics by laying the foundations of quantum mechanics and special and general relativity. In this paper we briefly review how some of these thinkers have looked at the issues of the value of science, the relationship between science and philosophy, and the importance of Greek philosophy to nuclear physics and quantum theory.

"The paper presents results from computer simulations performed on a model of an RF electron source for the Laser Compton Scattering (LCS) γ-ray system. The new LCS γ-ray system is under implementation at ELI-NP/IFIN-HH. Different configurations of the system modelled with the ASTRA software package and different setings on the system components were analysed to optimize the inital beam parameters before acceleration up to ultra-relativistic energy in linac. The properly designed RF electron source contibutes significantly towards delivery a high brightness beam, which is a crucial specification for the LCS γ-rays systems."
