Lectures by Anna Backerra
The presentations range in level from widely accessible to academic. The duration, level and contents can be adapted to suit the target audience. The overview below assumes about 40 minutes before the break, 30 minutes after the break, and a 10 minute question and answer session. Depending on the subject, fragments of classical music, illustrations, equations or a combination of them are incorporated.
1. Academic lectures about complementary language and twin physics
Level: For students and graduates in physics, mathematics and philosophy.
These lectures are based on the book “Twin Physics, the Complementary Model of Phenomena” (see “Publications”). A complementary mathematical language is presented, reflecting a dualistic way of considering the universe, in which determinate and indeterminate aspects of phenomena are mutually independent and occur joined in nature. This seems to be a revolution in scientific thinking.
The basic item in twin physics is the Heisenberg-unit, defined as a constant amount of potential energy; only by interaction with another one, actual energy is generated. Space is upgraded to an energetic object as prominent as mass. When applied on physics, twin physics creates a bridge between large- and small-scale phenomena and so between quantum-mechanics and gravity. The laws of Maxwell emerge in an easy way. Many phenomena can be described in detail, up to neutron decay, dark matter and gravitational waves.
2. The twin model, human behavior in a new perspective
Level: Particularly appropriate for psychologists, social scientists and therapists. No specific prior knowledge of physics is required.
The influence of complementarity in everyday life is explained and combined to the so-called ‘twin model for human behavior’. Attention is directed to the consequences for gender differences and human relationships in general, including homosexuality. Questions which may come up for discussion: To what extent is humanity bound by the laws of physics? How can a balanced development be stimulated? What perspectives does the twin model offer for health?
These lectures are based on the book “Het Gevlochten Bestaan” (The intertwined existence, see “Publications”), in which the nature of complementarity is considered.
3. The historical link between physics and music.
Level: A basic knowledge of classical music and physics is assumed. For people who are interested in classical music as well as (popular) physics. Many short musical examples will be played.
Comparing revolutionary innovations in music and physics, it becomes apparent that these discoveries have been occurring in the same periods for years. A deeper understanding of both disciplines can be achieved through this process. Musical examples from the 16th up to the 20th century will be played and placed in the context of discoveries from the field of physics. Surprising analogies can be found in the manner in which innovations in both disciplines have followed each other.
Keywords music: Gregorian, polyphony, Gesualdo, Bach, Beethoven, Debussy, Schönberg, dodecaphony, Vermeulen, Cage, Boulez, aleatorics, Ligeti, Lutoslawski, serialism, Cage, Boulez, Stockhausen, Andriessen, and more.
Keywords physics: Galileo, Newton, gravity, X-rays, Planck, quanta, Einstein, theory of relativity, quantum mechanics, Heisenberg, complementarity, chaos theory, subatomic particles, and more.
4. The flirtation between physics and music in the 20th-21st century.
Level: For music students and fans of avant-garde music. A highly relevant and topical lecture, in which some familiarity with 20th century experimental music is assumed. Many short musical examples will be played.
Enormous changes in all kinds of fields took place; in the course of the 20th century, composers found answers to the new issues that had arisen. Starting with dodecaphonics, we consider several successive styles, like aleatorics, serialism and minimal music.
At the start of the 21st century, the lecturer combined Schönberg’s insights with Allen Fort’s ‘set theory’ to a new tonal system: relative tonality. This provides a tool to expand the tonal possibilities, used to its limits during the romanticism. It offers a new harmonic foundation for contemporary music, far beyond romantic applications. A few examples of this neo-classical style will be played.
Composers: Schönberg, Vermeulen, Cage, Boulez, Ligeti, Lutoslawski, Cage, Boulez, Stockhausen, Andriessen, Backerra, and more.
