Lectures by Anna Backerra

The lectures are in Dutch language or, if desired, in English. The range in level reaches 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, many fragments of classical music, illustrations, equations or a combination of them are incorporated.

1. The twin model: human behavior in a new perspective

Level: no prior knowledge of physics is required.

Particularly appropriate for feminists, psychologists, social scientists and therapists.

The existence 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. Questions which may come up for discussion: What perspectives does the twin model offer for our health? How can a balanced development in a relationship be stimulated? What does the twin model say about homosexuality? To what extent is humanity bound by the laws of physics? Where is the disconnect between male and female behavior coming from?

Based on the book ‘Het Gevlochten Bestaan’, in which the nature of complementarity is considered (see ‘Publications’; only in Dutch language).

2. The historical link between physics and music

Level: basic knowledge of classical music and physics is assumed.

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. Many musical examples from the 16th up to the 20th century will be played, and placed in the context of discoveries in the field of physics.

Keywords music: Gregorian, polyphony, Gesualdo, Bach, Beethoven, Debussy, Schönberg, dodecaphony, Vermeulen, Cage, Boulez, aleatorics, Ligeti, Lutoslawski, serialism, Cage, Boulez, Stockhausen, Andriessen.

Keywords physics: Galileo, Newton, gravity, X-rays, Planck, quanta, Einstein, theory of relativity, quantum mechanics, Heisenberg, complementarity, chaos theory, subatomic particles.

3. The flirtation between physics and music in the 20th century

Level: basic knowledge of 20th century experimental music and physics is assumed.

In the course of the 20th century, enormous changes in all kinds of fields took place. Composers found musical answers to the new issues that had arisen. In the second half of the 20th century, audiences often found the numerous musical experiments carried out at the time hard to grasp. Gradually, tools were developed that made it possible to link those new notes in a more acceptable context.

After a short historic overview we consider several successive styles, like dodecaphonics, aleatorics, serialism and minimal music, and compare them with developments in physics. Many short musical examples will be played. The lecturer herself has combined Schönberg’s insights with Allen Fort’s ‘set theory’ to a new tonal system: relative tonality. This provides a tool to expand the romantic tonal possibilities to a new harmonic foundation for contemporary music. A few examples of this neo-classical style will be played.

Keywords: Schönberg, dodekafonics, Einstein, relativity theory, Vermeulen, chaos theory, quantummechanics, Heisenberg, complementarity, Cage, Boulez, serialism, Ligeti, Lutoslawski, aleatorics, subatomic particles, Stockhausen, Andriessen, Backerra and more.

4. Twin physics: a revolution in scientific thinking

Level: academic lectures for graduates and students in physics, mathematics and philosophy.

In the early days of quantum mechanics, no useful mathematical framework could be constructed to describe the wave-particle duality. Twin physics provides this missing link, reflecting a dualistic way of considering the universe, founded upon a complementary mathematical language.

With this model it is possible to describe Maxwell’s laws and the four forces of nature. Also a series of elementary particles is described, containing 4 types of electrons, 3 types of neutrons and 2 types of protons. A list of nine articles about twin physics can be found under "Publications"; they can be opened and downloaded under "Home". Most recent is article 9 in which a relation between Planck’s Constant and Speed of Light is derived.

Based on the book ‘Twin Physics, the Complementary Model of Phenomena’ (see "Publications").
