This leads into the statistics of gas molecules and the Maxwell-Boltzmann distribution of molecular velocities. The laws of thermodynamics are introduced, and the concept of entropy and the arrow of time are presented.

We also briefly discuss the partition into Classical and Modern Physics, the practical relevance of the topic and some of the a priori tools guiding physicists in their endeavour. In order to streamline the information, particularly for readers more interested in the recent developments in the field, in this Chapter and in the following one, much of the information has been relegated to self-explanatory figures and tables.

Now we are ready to discuss some of the most intriguing among the countless contributions of the physical methodologies to other sciences. New approaches have been developed, for which the emergence of new concepts, patterns, universalities and the cross-fertilization among different phenomenologies, matter more than the field of application. Some of them, such as Complexity , have been very fruitful and brought along with them a new perspective on science and the underlying reality.

Some of the common terms and concepts (e.g. force , velocity , acceleration , momentum ) are thus introduced and defined, as an introduction to the material of later chapters, where they will be extensively utilized. Since the book is devoted to readers with only a basic background of mathematics, some of the necessary mathematical tools and concepts are also briefly explained.

It is based on an array of ring-lasers, which are the most sensitive inertial sensors to measure the rotation rate of the Earth. The GINGER project is still under discussion; the experiment G-GranSasso is an R&D experiment financed by INFN Group II, it is studying the key points of GINGER and at the same time developing prototypes. In the following the signal coming out of a ring-laser and the present sensitivity are described.The prototypes GP2 and GINGERino and the preliminary results are reported. This project is inter-disciplinary since ring-lasers provide informations for the fast variation of the earth rotation rate, they are used for the rotational seismology and for top sensitivity angle metrology.

As on the Earth, the need for a navigation system becomes paramount, especially when we plan to build permanent planetary bases. In particular, this paper treats the case of a human outpost located at the lunar South Pole, and leverages a relativistic positioning algorithm in order to fulfill this goal. This mission is also intended as a test bed for similar future missions. Here, it is shown that it is possible to position users such as manned or unmanned rovers thanks to a constellation of 6 and then 12 nanosatellites orbiting around the Moon, with an accuracy of at most 100 m and 50 m respectively. In fact, the chosen highly elliptical frozen orbits provide coverage over an area centered at the South Pole and of 1500 km radius with at least 4 satellites always in view, which is the minimum number for our positioning algorithm to work. Each satellite is equipped with a clock so that it can emit pulse-like signals that are received by the user, which is equipped with another clock and so it is able to count the pulses emitted by the different nanosatellites. A ground station at the South Pole updates the ephemerides and the proper times of the satellites, transmitting them periodically to the users. In this paper we analyze the architecture of such a mission, describing in details the concept of operations, orbits, and nanosatellites subsystems, maximizing the use of components off the shelf. We also include an implementation plan and a cost model, highlighting the sustainability of the project. Finally, a set of ground tests to qualify this mission for lunar orbit is described, and its top five technical and programmatic risks are discussed
