Physics takes the biscuit

Why did a light-hearted experiment attract so much attention from the media? The episode is an interesting lesson for those wanting to explain science to the wider public — equations do not always scare people away. 
Pranks and Astronomical Antics
Some scientists take themselves and their work very seriously. However, there are plenty of cases of humour being combined with science. Here I review some examples from the broad fields of physicsExpand
Science Spoofs, Physics Pranks and Astronomical Antics
The physical sciences are usually taken to be very earnest pursuits by those who work in them. However, most professional physicists and astronomers would also happily agree with the t-shirt mantraExpand
On The Solution of Capillary Rise Dynamics
Capillary rise is one of the most well-known and vivid illustrations of capillarity; however, there is no solution as yet except certain segmental solutions for asymptotic regimes. This paper usedExpand
The Monotonic Rising and Oscillating of Capillary Driven Flow in Circular Cylindrical Tubes
Among the best-known capillarity phenomena is a capillary rise, the understanding of which is essential in fluidics. Some capillary flows rise monotonically whereas others oscillate, but until now noExpand
On the dynamics of capillary imbibition
The imbibition of wetting liquids in porous media takes place on length scales spanning several orders of magnitude, in phenomena ranging from landslide due to heavy rainfall in geophysics toExpand
Capillarity in Soft Porous Solids
Soft porous solids can change their shapes by absorbing liquids via capillarity. Such poro-elasto-capillary interactions can be seen in the wrinkling of paper, swelling of cellulose sponges, and mo...
Capillary rise of non-aqueous liquids in cellulose sponges
A cellulose sponge is a mundane porous medium composed of numerous microporous cellulose sheets surrounding macroscale voids. Here, we quantify the capillary rise dynamics of non-aqueous liquids in aExpand
Capillary Rise: Validity of the Dynamic Contact Angle Models.
The results show that the LWR equations modified by the molecular kinetic theory and hydrodynamic model provide good predictions on the capillary rise of all the testing liquids with fitting parameters, while the one modified by Joos' empirical equation works for specific liquids, such as silicone oils.

Characterizing Dissipation in Fluid-Fluid Displacement Using Constant-Rate Spontaneous Imbibition.
It is shown that a large fraction of dissipation can take place near the contact line, and rationalize the observations by means of a theoretical analysis of the dynamic contact angles of the front and back menisci of the oil slug. Expand
Methods for Nano-Crystals Preparation
Nanocrystals have the potential to address challenges in very different fields like production of computer chips, delivering drugs of low water solubility, cosmetic research and products,Expand


Capillary flow as the cause of ring stains from dried liquid drops
When a spilled drop of coffee dries on a solid surface, it leaves a dense, ring-like deposit along the perimeter (Fig. 1a). The coffee—initially dispersed over the entire drop—becomes concentratedExpand
