The Grand Law of Nature: The universe consists of local material (mass-energy) structures in forced equilibrium and their interactions via forced fields. The forces are balanced at any time (including inertial - process rate forces) thus conserving momentum, while charges/mass and energy are transferred and conserved during forced displacement in space all the times, but energy is degraded (dissipated) as it is redistributed (transferred) from higher to lower non-equilibrium potential towards equilibrium (equi-partition of energy)-(by M. Kostic)
The spontaneous forced tendency of mass-energy transfer is due to a difference or non-equilibrium in space of the mass-energy space-density or mass-energy-potential. As mass-energy is transferred from higher to lower potential, and thus conserved, the lower mass-energy potential is increased on the expense of the higher potential until the two equalize, i.e., until a lasting equilibrium is established. THAT explains a process tendency towards the common equilibrium and impossibility of otherwise ... Read More
DEFINITION of ENERGY: Energy is a fundamental property of a physical system and refers to its potential to maintain a system identity or structure and to influence changes (via forced-displacement interactions) with other systems by imparting work (forced directional displacement) or heat (forced chaotic displacement/motion of a system molecular or related structures). Energy exists in many forms: electromagnetic (including light), electrical, magnetic, nuclear, chemical, thermal, and mechanical (including kinetic, elastic, gravitational, and sound) ... Energy is the ‘‘building block’’ and fundamental property of matter and space and, thus, the fundamental property of existence. Energy exchanges or transfers are associated with all processes (or changes) and, thus, are indivisible from time. If all energy is literally expelled from a confined space, then nothing, empty space will be left. As long as any matter is left it will contain the energy - even at zero absolute temperature the electrons will be orbiting around very energetic nucleus. Matter is and must be energetic, E=mc^2, thus literally, "energy is everything," no energy, nothing in the space (see also Definition of Entropy and The 2nd Law).

Professor Kostic's teaching and research interests are in Thermodynamics (a science of energy, the Mother of All Sciences), Fluid Mechanics, Heat Transfer and related fluid-thermal-energy sciences; with emphases on physical comprehension and creative design, experimental methods with computerized data acquisition, and CFD simulation; including nanotechnology and development of new-hybrid, POLY-nanofluids with enhanced properties, as well as design, analysis and optimization of fluids-thermal-energy components and systems in power-conversion, utilizations, manufacturing and material processing. Dr. Kostic came to Northern Illinois University from the University of Illinois at Chicago, where he supervised and conducted a two-year research program in heat transfer and viscoelastic fluid flows, after working for some time in industry.
"Kostic’s unique synergy of philosophical, theoretical, computational and experimental approach, results in open mind, intense curiosity and sharp focus for identifying and analyzing natural and engineering phenomena with high motivation for problem identification, troubleshooting and solving."
Kostic received his Dipl-Eng (B.S.) degree with the University of Belgrade Award as the best graduated student in 1975. Then he worked as a researcher in thermal engineering and combustion at Vinca-Belgrade Institute for Nuclear Sciences, which then hosted the headquarters of the International Center for Heat and Mass Transfer, and later taught at the University of Belgrade in ex-Yugoslavia (*). He came to the University of Illinois at Chicago in 1981 as a Fulbright grantee, where he received his Ph.D. in mechanical engineering in 1984. Subsequently, Dr. Kostic worked several years in industry. In addition, he spent three summers as an exchange visitor in England, West Germany, and the former Soviet Union.
Dr. Kostic has received recognized professional fellowships and awards, including multiple citations in Marquis' "Who's Who in the World," "Who's Who in America," "Who's Who in American Education," and "Who's Who in Science and Engineering"; the Fulbright Grant; NASA Faculty Fellowship; Sabbatical Semester at Fermilab as a Guest Scientist; and the summer Faculty Research Participation Program at Argonne National Laboratory. He is a frequent reviewer of professional works and books in Thermodynamics and Experimental Methods. Dr. Kostic is a licensed professional engineer (PE or P.Eng.) in Illinois and a member of the ASME, ASEE, and AIP's Society of Rheology. He has a number of publications in refereed journals, including invited state-of-the-art chapters in the Academic Press series Advances in Heat Transfer, Volume 19, and "Viscosity" in CRC Press' Measurement, Instrumentation and Sensors Handbook; as well as invited reference articles: Work, Power, and Energy in Academic Press/Elsevier's Encyclopedia of Energy; Extrusion Die Design in Dekker's Encyclopedia of Chemical Processing; and Energy: Global and Historical Background, and Physics of Energy, both in Taylor & Francis/CRC Press Encyclopedia of Energy Engineering and Technology. Professor Kostic is a senior member of the Graduate Faculty at Northern Illinois University (See C-Vita for more information).
Let's turn Ideas into Reality! * Be aware of complexity but make it simple!
Thermodynamics, a science of energy, is the Mother of All Sciences!
...We have to look at history to better see the future...
...There is no beginning or end: yesterday is history, tomorrow is mystery, and today is a gift...
In the world of technology (often GIGO) we the people (with creativity and judgment) make the difference!
It is important to anticipate and be creative to resolve issues/problems timely and effectively.
