A quantitative approach to studying human biomechanics, presenting principles of classical mechanics using case studies involving human movement. Vector algebra and vector differentiation are used to describe the motion of objects and 3D motion mechanics are treated in depth. Diagrams and software-created sequences are used to illustrate human movement.
Physics explains everything from the beginning to the end of any complete
description of the human body. Such a comprehensive discussion should begin
with the basic structure of matter, as explained by quantum mechanics – the
physics at small dimensions, and end with the mechanics of human motion,
the energetics of metabolism, the fluid dynamics of blood flow through vessels,
the mechanisms for speaking and hearing, and the optical imaging system
we call the eye.
We normally think of the eye as an organ for vision, but due to the discovery of
additional nerve connections from recently-detected novel photoreceptor cells in
the eye to the brain, it is now understood how light also mediates and controls a
large number of biochemical processes in the human body. The most important
findings are related to the control of the biological clock and to the regulation of
some important hormones through regular light-dark rhythms. This in turn means
that lighting has a large influence on health, well-being and alertness.
This is a further development of my last book Brain, Mind, and the Signifying Body(Thibault
2004a). That book was a first step in an overall attempt to rethink meaning-making activity
from the perspective of the body-brain system – the signifying body – embedded in its ecosocial
Every clinician knows that the human relationship with the person diagnosed with a psychotic
disorder and particularly schizophrenia is the cornerstone of effective therapy and
the foundation for recovery. This was one of the major tenets of an earlier generation of
psychotherapeutic effort in schizophrenia and related psychoses but had drifted out of focus
during the 1980s with the rise of an excessively narrowbiological psychiatry and the decline
of the traditional psychoanalytic approach.
Human efforts to conquer flight, land on the moon, go beyond the earth and discover new
universes would have been difficult without the development of wind tunnels. The early
18th and 19th century aerodynamists used whirling arm to study various shapes which suf‐
fered from a major fault that the body under investigation was forced to fly in its own un‐
disturbed wake. This has lead to the development of wind tunnels to overcome the problem.
Sciences (EHS) is a dynamic group of
faculty and students exploring the impact
of chemical, biological, and physical agents
on human health. We work to discover the
sources and distribution of these agents;
understand individual response at the
molecular, cellular, organ, and whole-body
levels; assess environmental risk and devise
prevention and intervention strategies.
Current thinking on the environment and
health has propelled us to consider how the
built environment and the social environment
influence human health beyond the
traditional focus on hazardous agents.
