Silicosis is lung disease caused by the inhalation of respirable dust that contains quartz or similar particles. These particles can embed themselves deeply in the lung and the reaction of the tissue is called silicosis.…
The Batchelor Prize for 2020 is awarded to Professor Alexander J Smits, Eugene Higgins Professor of Mechanical and Aerospace Engineering, Princeton University
By improving our understanding of turbulent flow over canopies we can design better cities to improve air quality. This is just one of the applications of the work of Alfredo Pinelli, a professor at City University of London working on Large Eddy Simulations (LES) of turbulence.…
Current underwater vehicles are rigid in structure which limits their suitability for many tasks required for ocean exploration. Francesco Giorgio-Serchi is working with a team at the University of Southampton to design new robots based on squids and octopuses that are made entirely from silicone.…
Removing water from your ear canal by shaking requires an acceleration 10 times that of gravity according to research from Sunny Jung at Virginia Tech (now Cornell).…
Following the Deepwater Horizon oil spill in 2010, scientists at the University of Cambridge have been studying underwater plumes to try to understand how the Earth’s rotation affects the spread of oil.…
Pollen is the main source of protein in a honey bees diet and so it’s essential that they are able to carry enough of it safely back to the hive.…
The air density on Mars is 1/100th of that on Earth which means that current airborne vehicles cannot be used to explore the planet.…
How are dandelion seeds able to travel distances of over 150km across oceans, with only small feathery bristles and the power of the wind?…
Citrus fruits contain small pockets of liquid which burst upon contact releasing a jet of strong smelling oil into the air.…
Beyond its theoretical contribution, this work also has signi cant practical impact. It provides new and important insight into how to adapt and optimize the performance of compressed sensing in practical applications. It introduces a new generation of sampling strategies based on multilevel random sampling which are both theoretically optimal and outperform previous state-of-the-art approaches in practice. It has led to new approaches in MRI, NMR, uorescence microscopy and helium atom scattering which offer signi cant performance gains.
In the year 1781 the problem of optimal transport was first formally discussed by the French mathematician Gaspard Monge. The major point in this field is the task of transforming a probability measure into another one in the way that consumes least energy.…
Air-tables create a thin film of air capable of supporting objects and causing them to levitate. By adding grooves to the table or the object, Professor John Hinch at the University of Cambridge was able to control the objects motion and describe the resultant acceleration in terms of a simple scaling relationship involving gravity and the aspect ratio.…
Using the surface tension of water and a hydrophobic coating on their legs, many insects are able to walk on water.…
Freezing bubbles are not only beautiful, but also demonstrate incredibly complex physics. Here, Professor Jonathan Boreyko explains how bubbles freeze with examples of slow motion videos filmed in his laboratory at Virginia Tech.…
Measuring the forces present in an avalanche using light. Amalia Thomas from the University of Cambridge explains how to measure the forces between colliding particles in an avalanche based on their photo-elastic response and refractive index.
The brazil nut effect describes the movement of large particles to the top of a container after shaking. The same effect also occurs in avalanches where large blocks of ice and rocks are seen on the surface, and in a box of cereal where the large pieces migrate to the top and the smaller dusty particles remain at the bottom.
Five-time Olympic Biathlon Skiing Champion Martin Fourcade enlisted the help of two scientists - Caroline Cohen and Christophe Clanet at Ecole Polytechnique - to help to decide the best type of wax to use on his skis in the 2018 PyeongChang Winter Olympics. Here's how they did it...
Female musicians from the northern islands of Vanuatu use the water surface as an instrument to create a variety of unique sounds – slap, plunge, plow – which they accompany with singing.…
Vortex ring collisions are incredibly beautiful and also incredibly complex. Ryan McKeown of Harvard University explains his amazing experiments visualising colliding vortex rings and their transition to turbulence.…
With the nomination period for the 2020 Batchelor Prize coming to a close at the end of the month (31st May 2019), Dr Tom Crawford spoke to the previous winners to find out more about the legacy of the award.
By bouncing elastic spheres across the surface of Bear Lake in Utah, researchers have discovered the physics behind stone skipping. The mechanism of ‘water walking’ occurs when a deformed sphere rotates continuously across the surface of the water giving the appearance that the sphere is literally walking on water.…
Cooking oil in a frying pan can be dangerous when the ‘explosive’ droplets touch your skin, but new research shows that they also increase the risk of indoor air pollution if not properly ventilated.…
Plesiosaurs ruled the oceans during the time of the dinosaurs with specially adapted flippers that enabled them to swim faster and with greater efficiency than any other animal.…
Rhonda Righter is joining the editorial board of the journal Probability in the Engineering and Informational Sciences. She brings with her a wealth of knowledge in the area of stochastic modelling and optimization; read her full biography here.…
Forum of Mathematics has announced the appointment of six new members to their editorial board: Mohammed Abouzaid, Jacob Fox, Patricia Hersh, Bernhard Keller, Peter Keevash and Ulrike Tillmann.…
Renewable sources of energy such as wind and solar power are becoming commonplace across the world, but yet it often seems that we are still searching for the renewable resource that will revolutionise the energy industry.…
In recent years, applied analysis has seen an increase in interest in neural networks.
Q&A with Yuri A. Kuznetsov and Hil G. E. Meijer, authors of Numerical Bifurcation Analysis of Maps: From Theory to Software Why would you write in the age of Open Access?…
In support of International Women’s Day, we celebrate the contributions of 15 of the most influential women throughout the history of computer science.…
Cambridge is saddened by the passing of two remarkable mathematicians in recent weeks, Sir Michael Atiyah and Sir Peter Swinnerton-Dyer. Both men made an indelible mark in the subject, with Atiyah receiving the Fields Medal in 1966, and Swinnerton-Dyer postulating the Birch Swinnerton-Dyer Conjecture.…
