This chapter details Dmitrii Mendeleev's turn to gas laws. In 1871, Mendeleev's successes lay far in the future. However, his bold predictions of 1871 had two glaring deficiencies: they were unsubstantiated, and they were not in the chemical tradition. The whole thing smacked of physics, and, as the chemist abandoned his half-hearted attempts to uncover his missing elements, his wavering attention shifted to that science. In the eyes of his peers, Mendeleev had abandoned his chemical guesses—and chemistry altogether—in favor of subsidized research on gas laws, of all things. This new, broadly conceived gas project would dominate his attention throughout the 1870s, but, in contrast to the repeated successes of the periodic law, every aspect of the effort would end in dramatic failure.

The illustrious question by German Astrophysicist R. Emden, “Why do we have winter heating?” has been re-examined for air following both the ideal and imperfect gas laws; the internal energy of the air in the room remains unaffected in the former case whereas it increases marginally for the latter one. The findings corresponding to ideal gas law were correlated by Emden with the mass of a person which does not change even though food is constantly consumed. This example corresponds to adulthood when the mass of a person remains more or less constant. But the marginal change of internal energy in the case of van der Waals gas is consistent with three stages of a person — initially a person grows during childhood followed by adulthood when he has more or less constant weight and finally in old age, it deteriorates.

Gas Laws summarizes the general laws that describe how the volume of a gas changes in response to changes in pressure (P), temperature (T in Kelvin) or the number of moles (n). The ideal gas law, which combines Boyle’s law, Charles’s law and Avogadro’s law, is presented, with explanations of using it to solve gas-law problems. Mathematical rearrangements of the ideal gas law to determine density and molar mass are described along with the use of Dalton’s law of partial pressures to find the pressure of each gas in a mixture. Finally the chapter presents ideal gas law and reaction stoichiometry, Graham’s law of effusion, and basic notions of real gases and their deviation from the ideal gas laws.

In investigations involving gases at high pressures it is as essential to know the relative densities of the media concerned as it is their actual pressures. This demands a knowledge of the deviations from the ideal gas laws over wide ranges of pressure and temperature for each particular medium. Although reliable data are available for the commoner single gases, with perhaps the exception of carbon monoxide, as yet little is known concerning the compressibility of mixtures, except generally that neither the Law of Partial Pressures nor the Law of Additive Volumes is strictly obeyed. In this connection the recent researches of Masson, Verschoyle, Bartlett, Keyes and their co-workers have been very informative, yet a great deal more work needs to be done before such lacunæ in our knowledge of such matters are filled.

The future of cardiothoracic surgery faces a lofty challenge with the advancement of percutaneous technology and minimally invasive approaches. Coronary artery bypass grafting (CABG) surgery, once a lucrative operation and the driving force of our specialty, faces challenges with competitive stenting and poor reimbursements, contributing to a drop in applicants to our specialty that is further fueled by the negative information that members of other specialties impart to trainees. In the current era of explosive technological progress, the great diversity of our field should be viewed as a source of excitement, rather than confusion, for the upcoming generation. The ideal future cardiac surgeon must be a "surgeon-innovator," a reincarnation of the pioneering cardiac surgeons of the "golden age" of medicine. Equipped with the right skills, new graduates will land high-quality jobs that will help them to mature and excel. Mentorship is a key component at all stages of cardiothoracic training and career development. We review the main challenges facing our specialty�length of training, long hours, financial hardship, and uncertainty about the future, mentorship, and jobs�and we present individual perspectives from both residents and faculty members.
