Even more applications for graphene (continued)

The Nobel Prize in Physics 2010 was awarded jointly to Andre Geim (see note [1] below) and Konstantin Novoselov for their groundbreaking experiments regarding the extraordinary properties of two-dimensional carbon. Nowadays, the burgeoning cornucopia of applications is such that a 21st century individual can literally kit themselves from head to toe with accoutrements which feature […]

Sound Pressures Generated by Exploding Eggs

The claims made in lawsuits – and the need to verify or disprove them – sometimes spark interesting research. The Acoustical Society of America’s Fall 2017 meeting included a report titled, “Sound pressures generated by exploding eggs”. Investigators Anthony Nash and Lauren von Blohn began this research thanks to a lawsuit: A restaurant had hard-boiled […]

Data Communications via Wet String, or via Hungry Snail

A wet string works, for sending information from one computer to another, says a new experiment. This adds to the list of low-tech ways to move data, the most lively method involving a hungry snail. The string experiment is reported on the RevK’s Rants web site, with the headline “It’s official, ADSL works over wet […]

“Egg unboiling machine enables graphene battery development”

“Egg unboiling machine enables graphene battery development,” is the headline in Mining Weekly. The article itself says: The Australian researchers who successfully unboiled an egg are turning their attention to capturing the energy of graphene oxide to make a more efficient alternative to lithium-ion batteries. The Flinders University team in South Australia has partnered with Swinburne University of Technology in Victoria, ASX-listed First […]

Sleep to forget teacher, or sleep to remember grandmother?

It seems that a lack of sleep may prevent the brain from forgetting unimportant information. A lack of sleep may also prevent the brain from remembering important information. How can scientists make sense of this seemingly-nonsensical seeming-contradiction? Imagine you just met your child’s teacher, who is named Gwen. The name Gwen, however, is firmly associated […]

Modelling heat loss from a semi-spherical cow udder

Theoretical physicists are sometimes accused of making over-simplifications for mathematical models. This has lead to many variations on the spherical cow story, where a physicist claims to be able to cure a sick cow, but only if it is a spherical cow in a vacuum. Oddly, most iterations of this tale ignore heat radiated from […]
