The two computer scientists are guest speakers at the 1. Heidelberg Laureate Forum (HLF), a week-long symposium for and by a number of the best contemporary mathematicians and computer scientists.
Raj Reddy, a pioneer in speech recognition, gave today the opening talk on the multilayered history of the modern computer. He will also explain why there are several people who could stake the claim to have “invented the computer”.
Raj Reddy, the longstanding professor at Stanford University and computer scientist, began dealing with the topics of artificial intelligence and human-computer interaction in the 1960s, and he was particularly interested in machine speech recognition. At that time, such research was considered revolutionary, as the computers of the 1960s were still run on punch cards and were able to perform at a mere fraction of the speeds of today’s computers. Reddy was the first to develop a concept for computers to process spoken words. In 1994, he received the Turing Award for his groundbreaking research; this award is recognized as the highest distinction in computer science, quasi the Nobel prize of computing. Reddy’s research findings can be found in many products today, such as the GPS unit that we could hardly imagine doing without.
Raj Reddy began his career in research at a hotbed for computer science, namely Stanford University. His doctoral advisor, John McCarthy, also received the prestigious Turing Award. Reddy dedicated his efforts to the question of how sound waves could be processed by a computer: After recording speech on tape, he then was able to break down the sound waves into smaller segments, which correspond to either a vowel or consonant. Reddy developed a model for a database matching system that can search for the best match for any segment. After he entered a glossary into the system, his program was then able to successfully identify which words were spoken. In one experiment, he was able to control a robotic arm by voice commands; and this was in 1968! Six years later, he unveiled “Hearsay”, one of the first computer systems to recognize natural language. This system was comprised of several basic technical concepts that are still used today. For example, the ability to automatically adapt to a speaker who pronounces words differently. This aspect, along with many other innovations from his research, can be found in numerous commercial systems today.
At the end of the 1970s, Reddy began to expand his field of research. In addition to robotics and human-computer interaction, he increasingly focused on the role of technology in modern society and how it could help to improve the living conditions of the poorest populations in the world. As part of these efforts, Reddy successfully completed “The Million Book Project” in 2007. This pilot project is aimed to provide every human being with unfettered access to information. Still today, Reddy continues to focus his efforts on improving the opportunities for education regardless of age and national or cultural boundaries. In this regard, the pioneer of computer technology did not pass up the chance to take part in 1.Heidelberg Laureate Forum (HLF) where he will be able to share his experiences and knowledge. The HLF allows 200 of the finest young researchers in computer science and mathematics to meet award-winning scientists like Raj Reddy to discuss scientific concepts and ideas: We are eager to see what the computerized world of tomorrow will look like.

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.
