The applications that Prof. Yerushalmy developed, in cooperation with Arik Weizman and Zohar Shavit of the University of Haifa Computer Science Department with support from Eurocom Israel, can be installed on most cellular phones on the market today. When installed, they enable cellular phones to function like computers which, among other things, are able to perform mathematical functions at different levels – from elementary school geometry to high school level calculus. The applications were developed specifically for the educational system, and they can be used like any application installed on a cell phone. The availability of the medium means that students are no longer reliant on computer classrooms in the school and that educational opportunities are as mobile as students are.
"I believe that mathematics needs to be learned in creative ways, and not by memorization and repetition. Just as physics and biology labs teach through experimentation, I believe that there should also be math labs, where learning is experiential," said Prof. Yerushalmy. According to Prof. Yerushalmy, computerized math labs like these have been developed in the past, but the cost of computers and the limited availability of computer classrooms limited their use. Cellular phone applications are accessible to both teachers and students on the school campus, on the way home or just about anywhere else.
Using cellular telephones provides another advantage: enabling creation of a community of learners. The applications enable users to send graphs and formulas to one another as short text messages (SMS), allowing them to work together to solve problems and involve any number of people to share in the learning process.
A pilot research project, recently completed in the University of Haifa Faculty of Education, evaluated students' use of the applications. As part of the research, participants recorded simple occurrences such as the speed of a dripping faucet, buses pulling away from a bus stop and a number of other events with the video cameras on their cell phones. They were then instructed by Dr. Galit Botzer, who conducted the research, to turn their video clip into a mathematical model using the applications available on their cell phone.
"It was important for us to see whether or not the students actually do use their phone as a medium for communication to help solve the problem. We found that they did indeed use text messaging to send one another information, questions and comments at different times and from different places. Our next step is to engage in more intensive research, and to develop additional, unique applications for cellular phones," said Dr. Botzer.

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
