Physiological Records Projected on a Screen
Signals from inside the body are the organ’s scriptures with messages telling what they do and how they feel
The Good Old Blackboard and Chalk
Teaching means to transmit a message to others and usually expects nothing in return. Many animal species teach their offspring how to hunt and protect themselves from predators, but this is not teaching in the human sense; it is instinct
The Tango
The perception of music is a complex subject not yet fully understood that has led to a huge bibliography spreading from its physics foundations to mathematical descriptions, from a neurophysiologic basis to psychological aspects, but also setting its feet strongly on cultural facets
A History of the Convolution Operation
For applied mathematicians, physicists, and engineers, there is no doubt of the usefulness and applications of the continuous convolution operation (CCO)
Intracardiac Pressure–Volume Diagrams and Their Links with Thermodynamics
The main objective of this column is to historically connect the pressure–volume diagram (PVD) of the heat mechanical engines and that of the heart
Strange Musical Rhythms
Music, along with its attached rhythm, has been with man for centuries, developing and evolving along with him. Its influence on human behavior and mood can reach levels whose limits are still unknown, especially in everything related to perception, where the whole nervous system is involved
Scientific Discoveries and Technological Inventions: Their Relativistic History Effect
In the theory of relativity, time dilation is a difference of elapsed time between two events as measured by observers either moving relative to each other or differently situated from gravitational fields. It means that astronauts return from space having aged less
Máximo Valentinuzzi (1907–1985): Perhaps the First Latin American Biophysicist, Biomathematician, and Bioengineer
My father was always studying, full of dedication and encouragement, my mother always pushed me to study, later on my wife, during our 55 years together, backed me up to study while she also kept studying
