Conference on measurements and time

The LNE is continuing its “Les mesures et…” series of conferences, with the fifth “Les mesures et le temps : quel futur ?” conference on May 15, 2025. “.

De l’astronomie aux horloges atomiques, une fabuleuse épopée de la mesure du temps

[conference in French]

Since ancient Egypt, humans have deployed remarkable techniques and strategies to push back the limits of precision in time measurement.

In this lecture, you’ll discover how, in the mid-twentieth century, quantum physics supplanted astronomy to produce time measurements with atomic clocks whose current accuracies reach 18 digits, corresponding to a drift of just one second over 15 billion years. This precision is not ultimate, and will have to be further improved to meet the major challenges of science and society, with a necessary change in the definition of the unit of time, the second, planned for the next decade.

The 2024 IEEE Ultrasonics, Ferroelectrics, and Frequency Control Joint Symposium will take place September 22 – 26, 2024 at the Taipei Nangang Exhibition Center in Taipei, Taiwan. This joint conference celebrates the 70^th anniversary of the IEEE UFFC Society.

The following conferences will be involved:

• International Ultrasonics Symposium (IUS)
• International Symposium on Applications of Ferroelectrics (ISAF)
• International Frequency Control Symposium (IFCS)
• Piezoresponse Force Microscopy Workshop (PFM)

The European Frequency and Time Forum (EFTF) is the Europe’s leading technical conference for time and frequency products and related technologies. The congress brings together researchers and technologists from manufacturers, service providers, operators, application developers, National Metrology laboratories, defense timing, and standards bodies to share the latest information and promote the development of precise time and frequency systems and components.

The conference will comprise invited plenary presentations as well as parallel oral and poster presentations. Last held in Neuchâtel in 2014, the 2024 edition of the conference will once again be held at the University of Neuchâtel, in the beautiful lakeside city of Neuchâtel, Switzerland. The main conference venue is the Aula de Jeunes Rives. This will mark the 37^th edition of EFTF.

The 9th Symposium on Frequency Standards and Metrology will be held at the Mantra on Salt Beach Resort, Kingscliff, NSW, Australia, 16-20 October 2023. For more detail, please see here.

First Lunar Laser Ranging (LLR) Meeting, September 14^th and 15^th, 2023 in Grasse, France

Observatoire de la Côte d’Azur (OCA), CNRS – INSU, Université Côte d’Azur (UCA), France

The first LLR meeting wishes to bring the producers, the users and the science behind lunar laser ranging together in order to join efforts and resources, to define goals and enhance the visibility for a LLR community, and to identify synergies and to plan for the future. The goal is to encourage every group to help and form a visible global community.
