Digital twin technology means a lot for flood preparedness, drainage and wastewater management and a host of other things in the water sector and beyond. It also has a lot to do with running business differently as the knowledge obtained from digital twins, including how to aggregate and visualise data, has large potential to shape the future of decision-making and data.
For those unaware, digital twin is a bit of buzzword that is catching on in academic, industry and policy worlds that refers to a live real time digital counterpart of physical systems we encounter in the real world. It’s closely related to what people in academia and industry also call ‘cyber-physical’ (more about this in our podcast on ‘The Fourth Industrial Revolution’).

As International Women’s Day was just last week it is a good time to reflect upon the women of today in STEM, and the pioneers of the past.
The role of women in STEM cannot be overlooked as it has been fundamental to the growth of science (including social science), technology and society as a whole. The history of science tends to under-represent women, however, there is a range of examples of women in the ranks of physics, chemistry, biology, archaeology, anthropology, civil engineering and many other fields throughout history.
I have had the pleasure of meeting and interviewing many brilliant women scientists, mathematicians and engineers throughout my career. People who have inspired countless others through research, teaching and simply living.
This video showcases some famous women scientists and engineers, some you may have heard of, others perhaps not so much. It’s important that we tell the stories of women in STEM for whom without science would be at a great loss, not to mention our future. Continue reading Remembering women in STEM
Absolute zero is really cold – −273.15 °C to be exact. At temperatures close to absolute zero matter begins to act strangely at an atomic scale.
In nature when matter undergoes a transition from one form to another, such as a liquid into a gas, it is known as a phase transition. In physics this is well understood and is present in many of the things we encounter in nature, not to mention the formation of the universe more generally. But at the quantum level phase transitions are even more involved and fascinating.
For starters it’s challenging to view them experimentally, although it is possible to catch glimpses of what is taking place, capturing the whole picture of what is happening during a phase transition is another matter. Very different systems show the same phenomena, a concept known as ‘universality’ in physics.
Extremely cold states of matter are tested in Bose-Einstein condensates in which atoms ‘gather’ together and behave as if they were a single atom, thereby allowing quantum effects to be visible on a much larger scale.
Condensates are incredibly exciting in physics, and are relevant across a broad range of conditions — from sub-atomic particles to the early Universe itself – leading to bizarre phenomena such as superfluidity and superconductivity, which are useful to technologies.
