What is digital simulation?

Digital simulation has become an almost mandatory step in developing new products. But what does “simulating behavior” or “modeling an event” really mean? Marius Preda, a computer science researcher at Télécom SudParis, explains what’s hiding behind these common industry expressions.   What is digital simulation used for? Marius Preda: Its main goal is to reduce […]

Could additive manufacturing be the future of the plastics industry?

There has been a significant revolution in the world of materials as 3D printing has proved its potential for innovation. Now it must be put into practice. While 3D printers are increasingly present in prototyping workshops, they have been slow to replace the processes traditionally used in the plastics industry. This is because these technologies […]

Silicon and laser: a brilliant pairing!

Researchers at Télécom ParisTech, in partnership with the University of California, Santa Barbara (UCSB), have developed new optical sources. These thermally-stable, energy-saving lasers offer promising potential for silicon photonics. These new developments offer numerous opportunities for improving very high-speed transmission systems, like datacomms and supercomputers. Their results were published in Applied Physics Letters last summer, […]

What is mechatronics?

Intelligent products can perceive their environment, communicate, process information and act accordingly… Is this science fiction?  No, it’s mechatronics! Every day, we come in contact with mechatronic systems, from reflex cameras to our cars’ braking systems. Beyond the technical characteristics of these devices, the term mechatronics also refers to the systemic and comprehensive nature of […]

What is a supercritical fluid?

Water, like any chemical substance, can exist in a gaseous, liquid or solid state… but that’s not all! When sufficiently heated and pressurized, it becomes a supercritical fluid, halfway between a liquid and a gas. Jacques Fages, a researcher in process engineering, biochemistry and biotechnology at IMT Mines Albi, answers our questions on these fluids […]

What is artificial intelligence?

Artificial intelligence (AI) is a hot topic. In late March, the French government organized a series of events dedicated to this theme, the most notable of which was the publication of the report “For a Meaningful Artificial Intelligence,” written by Cédric Villani, a mathematician and member of the French parliament. The buzz around AI coincides […]

Astatine halogen bond finally revealed!

Astatine is the last member of the halogen family, which also includes fluorine and chlorine. These chemical elements have a distinct feature: they are able to form an unusual kind of bond with molecules. Yet for astatine, the existence of this specific halogen bond had never before been proven. This is because in its natural […]

How working classes use digital tools: The Facebook example

For over a decade now, the use of digital tools and internet connectivity has greatly developed among households, including among working classes. Yet very few studies exist on this part of the population’s specific uses of digital technology. In the context of the Poplog project, which counts Télécom ParisTech among its partners, Dominique Pasquier, a […]
