Not the most glamorous part of ceramics, but rainy days are good to mix glaze. Anyone got a guess what color this turns out once it's fired?

Kathryn Beals is an excellent example that Art is a Science!! This Aura Magnetic Method Painting Technique by @kathrynbeals is incredible 😍 Creating new methods of art is incredibly exciting!!! . Kathryn has a video course showing how this method works that will come out on the 31st January 2020 and you can pre order this course now!! Visit @kathrynbeals for the preorder link 🤗 . . We are extremely proud that Kathryn has chosen to use our silicone moulds for the course 😊 The circular moulds will be back in stock very soon!! . . . . . . . #science #scienceisart #physics #technology #chemistry #research #art #space #nature #engineering #education #stem #scientist #facts #nasa #math #universe #love #memes #astronomy #artisscience #sciencememes #knowledge #mathematics #sciencefacts #school #innovation #life #just4youonlineuk #kathrynbeals (at Warrington, England) https://www.instagram.com/p/B7Lizc3nszT/?igshid=1k207dlykisl6

Drafting is an important part of the strategy in competitive swimming in open water or even in pools (practice and meets). It is well known that similarly to biking, car racing and running, you can save precious energy by positioning yourself (here after call the drafter) in the wake of another swimmer (the leader). In an experimental study, Westerweel et al. looked at this effect and found that the lead swimmer also benefits from the drafter but at a lower extend and can also take the advantage for certain positions during passing. To do so they used passive swimmer models (held fixed in a current) and looked at the impact of the drafter on the leader drag for a typical Froude number of 0.28 (equivalent of an average speed of 1.23m/s or 40” per 50m). They found that when the drafter is just behind, it saves up to 64% on the drag, while the leader has a maximum reduction of 20%. At almost a body length distance, the drafter still saves about 50% while the leader has no benefit. When swimming side-by-side, the drag is the same for the two swimmers and the drag can increase up to 50%. They looked at the drag in between these two configurations (when the drafter tries to pass the leader). Quite surprisingly they found that there exists a position near the shoulder of the leader for which the leader can take an advantage on the drafter! This could be used as a strategy to impede a passing swimmer in open water race and maybe even in a swimming pool where the lines would need to be accounted for. These results are for passive swimmers yet. The arms and legs motion can perturb the wake, but still this is quite exciting! Source: Westerweel, J., et al.

Since 1991 “the Ig Nobel Prizes honor achievements that first make people laugh, and then make them think.” Fluid dynamics won two prizes this year in the category Physics Prize and in the Fluid Dynamics Prize. The first one concerned a question that you probably have wondered about watching cats online: “are cats fluid or solid?”. This question was tackled by Marc-Antoine Fardin of Univ. of Lyon in 2014 [1] where he discusses the solid and fluid like behaviours of Felis Catus (or simply cats). In the first picture you can see different state of the Felis Catus materials: a) a solid state and (b-d) a fluid state. The second concerns a particular fluid, awarded of now three prizes by the community: COFFEE! [2] The first fluid dynamics prize on spilling coffee was awarded in 2012 to H. Mayer and R. Krechetnikov [3]. In the second picture, Jesse gave away a technique to record the acceleration of your coffee cup! Simply use your phone (and an apps like #phyphox). You better be in a not-spilling regime… [1] M.A. Fardin, On the rheology of cats, Rheology Bulletin, 83(2) July 2014 [2] J.

Sharks are indeed amazing animals. First they are not completely cartilaginous fishes! They have bones!!!Well in facts more like teeth with bones in it but on their skins. Their skin is covered in denticles which are composed of an outer enameloid layer and an inner bone-like layer. But most interestingly to us here is the effect of these denticles on their hydrodynamics. Indeed sharks are amazing swimmers and their skin has to do with it. George Lauder and co-authors have investigated this using 3 D printed inspired shark skin. The benefit is that contrary to traditional technique of shark skin study, where actual shark skin is used and then sanded (thus removing material), here the skin is 3D printed and the amount of mass well control as well as the reference flat “skin”. The results are even more interesting: they found that at “low speed” the shark like skin experienced drag reduction of about 9% and that while control in motion they could in certain swimming program measure an increase in self propelled velocity and a reduction of cost of swimming at the same time. It means that shark can save a lot of energy while swimming at low speed and as they swim all the time on a lifetime this is a significant save of energy. This study also shows that the roughness can help achieve highest speed at lower cost making shark great swimmers! The figure here shows a lemonshark and the denticles. credit images: image1: By Albert kok image2: By Pascal Deynat Reference: Biomimetic shark skin: design, fabrication and hydrodynamic function, Li Wen, James C.
