Project title: Flashing Water Drops
Field: PhysicsFlorian Ostermaier (19)
Henrike Wilms (20)
Visiting a stalactite cave last summer, one of us made a strange observation: Every time a drop fell down from the top it seemed as if it would flash at a certain height. We didn't know the explanation for this, so we tried to reproduce the phenomenon at home. Our first idea was to use the drops falling down from the water tap. Quite accidentally we found out, that the effect only occurred when we put a light source in a very special position towards the observer and the falling drop. Fascinated by this mystery we started doing some research on the strange flash in the air. During our work we found out the relevant factors and we can now exactly say, under which conditions these flashes occur. In addition to that we succeeded in describing the phenomenon mathematically and we know now, that the light reflections within a falling droplet change because the droplet itself oscillates. We also found out that this can be observed everywhere a drop detaches from anything like in the shower, at a water tap or raindrops falling down from gutters. With our research we found a completely new phenomenon that, as far as we know, has never been analyzed by anyone else so far.
Project title: Examination of Plants’ Self-Defence Against Pests
Márton Spohn (18)
Some plants, especially members of the mint family can defend themselves against their pests on a special manner: they emit scents that attract natural predators of the pests. This phenomenon was studied by biologists and chemists, but a contradiction remained unnoticed: chemicals that are held responsible directly for this effect cannot evaporate. My project was aimed at finding the reaction pathways taking place in the plant during an attack to convert the furanoterpenoides (chemicals responsible for self-defence) into volatile compounds. Experiments were made with plant extracts which mainly involved chromatographic methods to discover possible pathways. The experiment based effect mechanism model of furanoterpenoids can explain the rapid reaction of the plant to an attack despite of the fact that furanoterpenoide is produced very slowly. By discovering more details of floral self-defence, more environment-friendly pesticides may be developed.
Project title: An Extension of Wiener’s Attack on RSA Encryption
Abdusalam Abubakar (16)
In 1990 Wiener showed that if RSA is used with a small decryption exponent it can be successfully attacked. He based his attack on the properties of continued fractions, in particular on a very well-known theorem of Legendre concerning the approximation of irrational numbers by simple continued fractions. In 2004 Hinek proved that if a very large decryption exponent is used, the RSA system can be successfully attacked. Using a small decryption exponent, d, has the advantage of allowing rapid decipherment. It might be thought that this advantage could be retained by increasing d just beyond the range vulnerable to Wiener’s attack. In attacks of the Wiener and Hinek types the condition must be obeyed for the success of the attack to be guaranteed. I shall refer to this condition as the "n1/4 barrier". In this project I investigate attacks beyond the "n1/4 barrier".
