Professor Pavel L. Kirillov has died on October 8th, 2021, on his 95th year after a life as a husband, father, and an internationally renowned scientist, researcher, and educator in the field of nuclear engineering, thermalhydraulics, heat transfer, and two-phase flow. He was a passionate and dedicated in everything, what he has done and leaves an incredible legacy to the profession. He was born on August 20th, 1927 in Russia, and received his M.A.Sc. degree in thermal physics in 1950 (Moscow Power-Engineering Institute (MPEI) (МосковскийЭнергетическйИнститут (МЭИ)), Faculty of Physics and Power Engineering (Физико-ЭнергетическийФакультет), Ph.D. and Doctor of Technical Sciences degrees in 1959 and 1969, respectively. Professor Pavel Leonidovich Kirillov was a respected technical leader, mentor, and friend to innumerable students, researchers, scientists, and engineers, and he will be sadly missed by all, who had the privilege to know him.

The correspondence between Nikola Tesla and Orville Wright kept in the scientist's legacy in the Nikola Tesla museum: On the occasion of the 165th anniversary of the birth of Nikola Tesla

Nikola Tesla and the Wright brothers, Wilbur and Orville, have worked and created in the United States of America in the period comprising the last two decades of the 19th and the first half of the 20th century. All three of them were visionaries and creators of the modern technical age. In the Tesla's legacy, apart from his personal and technical items, press clippings, monographic and serial publications, there are also about 156,000 sheets of archival material which cover his entire life and work, both chronologically and thematically. Among these testimonies there are four original documents (a concept of a condolence letter, a copy of the sent condolence letter, a brief gratitude note and a formal invitation) that were exchanged between Nikola Tesla and probably Orville Wright, between 1912 and 1920. The oldest preserved document of their correspondence is the concept of Tesla's condolence letter to Orville Wright on the occasion of the death of his older brother. Two approved patents for the Wright brothers' aircraft model have been preserved as well, which testifies of the scientist's interest in their work and aviation research in general. Researching the correspondence between Nikola Tesla and Orville Wright, as well as the other documents from the scientist's legacy preserved in the Nikola Tesla Museum in Belgrade, we have tried to highlight the details of his acquaintance with the Wright brothers, that is, a small fragment of his life and work which has remained almost unknown until today. Results of the research, presented in the form of a scientific research paper, contribute to a better understanding of the aviation history and reveal new details from the life stories of our renowned scientist and the two famous aviation pioneers. The publication of exclusive documents from Tesla's legacy is a contribution to the wider scientific community and a new reference point for all the researchers who are to cover similar topics in the future.

In Honour of Distinguished Scientist and Seminal Hydrogeologist Professor Ghislain de Marsily

<p>Professor Ghislain de Marsily is an internationally renowned scientist famed for his contributions to groundwater hydrology and water management. He is a pioneer in the development of stochastic hydrogeology. This presentation will outline and explore the significant contributions made by de Marsily to hydrogeology as a whole and to stochastic hydrogeology in particular. It will examine the effect of his work on defining the discipline of hydrogeology as we know it today, and will go on to show the significant impact his students and colleagues continue to have, inspired by his passion, ideas and enthusiasm for a more sustainable, equitable future for all.</p>

Pintando una acción de difícil práctica: el Marqués de la Mina y táctica de la guerra anfibia

Jaime Miguel de Guzmán-Dávalos y Spínola (1690-1767) was one of the most prestigious soldiers of the Enlightenment. He wrote Máximas para la Guerra, a book of unquestionable value that was published upon his death. In this article, paraphrasing the words of the author mentioned in its title, we aim at studying the precepts of the renowned scientist on amphibious warfare to which he devoted a chapter of his work. Having in mind its unquestionable quality, and being far from the hagiographic idolatry, we are going to run its critical evaluation. Disembarking troops is one of the most complex military operations ever. Our study contains lessons that we consider to be most valuable as well as decisions that we view as not so beneficial. In addition to that we also tackle the aspects that in our opinion could have been presented and analysed by the author and were not included.
