For years, physicists were unable to take advantage of the advancements in computer algebra. Most systems were simply not able to handle the specialized rules and operators, non-commutative variables, and complex notation used regularly in physics calculations, with the result that physicists continued to find it easier to work their problems with pencil and paper. Fortunately, the situation has changed, with new advancements being made all the time that make the complex calculations of physics easier and more reliable.
In this webinar, learn more about recent advancements in computational physics, and see how these techniques can be applied to problems from general relativity, classical mechanics, quantum mechanics, and classical field theory. A recent project involving the digitization of the solutions to Einstein’s field equations shown in the book “Exact Solutions to Einstein’s Field Equations,” will also be presented.

No one said that finding out what the universe is made of and how it works would be easy. But at CERN, the European Organization for Nuclear Research, thousands of scientists are trying to do just that every day.
The development team at CERN has created many applications including the ROOT platform, a big data analysis for its High Energy Physics computing. These applications are used by more than 20,000 users to create cutting edge scientific software. Understanding that the quality of their application is critical for its large customer base, CERN adopted Agile practices like Continuous Integration (CI) and testing.
Please join this European webinar to hear how CERN implemented Electric Cloud’s scalable automation solution to build and test their complex software applications to improve their code quality and increase their release frequency.
Join this webinar to learn:
•How CERN validates their code quality when creating applications designed to identify the existence of sub-atomic particles

Physical chemistry and microengineering techniques are ever more important to tools in the medical and pharmaceutical industries, as well as fundamental biological and biochemical research. In this webinar we will discuss modelling techniques for analysing microfluidics, multiphase flows, heat and mass transfer, enzyme-catalysed reactions, and amperometric sensing techniques. We will focus on the use of these modelling methods for designing biosensors, bioreactors, and biological “lab-on-a-chip” devices. The webinar will include a modelling demonstration and a Q&A session.Read more >
For product designers, research scientists and engineers, a computational model that predicts the behaviour of a design is only the first step in the modelling process. Once a model has been solved the next step is to optimize the design. This might involve minimising the amount of material needed to safely support a structure, or maximising the throughput of a chemical in a chemical reactor. This optimization process can be automated using the Optimization Module in COMSOL Multiphysics®. You can pick one or more objective functions to be minimised, identify which modelling inputs can be varied to achieve the optimal design, and specify a set of constraints that a model must satisfy. In this webinar we will show you how to use the geometry optimization capabilities of COMSOL Multiphysics® version 5.2 to find the best designs quickly and easily. The presentation will feature a live modelling demo and finish with a Q&A session.Read more >

The aim of this webinar is to highlight the benefits of correlative microscopy for studies of graphene and related two-dimensional transition metal dichalogenides (TMDs) such as MoS2 and WS2. Raman Imaging is used to characterize the optoelectronic properties of 2D materials. In combination with AFM and SEM the precise geometric dimensions of these materials is determined. Photonic properties can be gained using SNOM.
Key learning objectives are:
Gain insight as to how unrivalled spectral and spatial resolution, ultra-fast acquisition times, and exceptional signal sensitivity in Raman Imaging can be combined with AFM, SNOM and SEM.
Learn which properties of low dimensional materials can be characterized with Raman and how complementary techniques lead to a more comprehensive understanding of the sample.
Learn how to configure a Raman microscope in order to perform high-sensitivity and high-resolution 3D spectral imaging routinely.
