Wer ist schon gern berechenbar? Ein Gespräch mit einer Welle über ihre Simulationen.

Stimme aus dem Nichts: Warum hat Gott nicht gesprochen „Es werde Schall!“?

Ich: Keine Ahnung.

Stimme aus dem Nichts: Hat er schon, es hat nur niemand gehört.

Ich: Sehr witzig. Wer ist da und warum sehe ich dich nicht?

Stimme aus dem Nichts: Ich bin Wavy, die akustische Welle. Du kannst mich nicht sehen, sondern
nur hören.

Ich: Das ergibt Sinn. Ich heiße David. Es freut mich dich endlich kennen zu lernen. Ich habe meine
Doktorarbeit über dich geschrieben.

Wavy: Ach ja? Um was geht es darin?

Ich: Ich habe Fehlerabschätzungen für Finite Elemente Lösungen von Wellengleichungen mit
dynamischen Randbedingungen bewiesen.

Wavy: Wie bitte? Wenn du glaubst mich durch „Fachchinesisch“ beeindrucken zu können, hast du
dich geschnitten.

Ich: Natürlich nicht, verzeih mir. Dann lass mich mit einer Frage beginnen: Weißt du wie ein
Mikrofon funktioniert?

Some persons claim that they are immune to advertising. We (that is Andreas Sturm, Jonas Köhler and David Hipp) can certainly not count us into that group of people: After multiple invitations over the central mailing list, we decided to participate in the CISM advanced school about ‘Computational Acoustics’  organized by Prof. Kaltenbacher (TU Wien) and sacrificed our Sunday and a holiday Thursday for the sake of scientific education.

CISM, International Centre for Mechanical Sciences, is a non-profit organization founded in 1968 and located in the beautiful and impressive Palazzo del Torso in Udine, Italy. The principal activity of CISM is the organization of courses, seminars, workshops and conferences to promote the exchange and application of advanced knowledge in mechanical science and in particular fields like robotics, biomechanics and environmental engineering.

Electromagnetic chirality

Posted on by

Dr. Ivan Fernandez-Corbaton from the Institute of Nanotechnology at the KIT presented his research in our CRC seminar April 21st. We are very happy to share his own short recap of his exciting talk on the question “How Electromagnetic Chiral is a Chiral Object?” with you:

Dr. Ivan Fernandez-Corbaton:
‘Take an object and place it in front of a mirror. If the “being in the other side of the mirror” handed you their version of the object, there are two possibilities: You can rotate it so that it is now identical to your original object, or you cannot. If you cannot, the object is called chiral. Try it at home with a wine opener and you will see that you will never be able to superimpose the two helices because they twist in opposite senses, as the two seashells in the picture.

Chirality is entrenched in nature: From the weak interactions between elementary particles to the empirical fact that most of the building blocks inside the human body are chiral (aminoacids, proteins, the DNA strands and many more).
