Will you be having fun with your robotic dessert wriggling or stationary?

Who eats whom?

Will robots eat us? Or will we eat robots? Each technophiles and -phobes have hungered to be taught which can occur first. The reply has now arrived, in a report from a workforce on the College of Electro-Communications in Tokyo and at Osaka College, Japan.

Reader Bruce Gitelman alerted us to this abstract passage: “We developed a pneumatically pushed edible robotic utilizing gelatin and sugar. We examined its perceived look and the members’ impressions when it was eaten.”

The researchers probed for the psychological reactions of their human topics. “We evaluated two circumstances: one by which the robotic was moved and one by which it was stationary. Our outcomes confirmed that members perceived the shifting robotic in a different way from the stationary robotic, resulting in various perceptions, when consuming it. Moreover, we noticed a distinction in perceived texture when the robotic was bitten and chewed underneath the 2 circumstances.”

That is one more instance (Suggestions beforehand talked about a case involving geese and monkeys) of the prescience of Stephen Sondheim when he wrote the musical Sweeney Todd: The demon barber of Fleet Avenue. Sondheim has Sweeney say: “The historical past of the world, my candy, is who will get eaten and who will get to eat!”

Ketchup inside

Sliceable sauces of many varieties have but to turn into in style. For the mo, technological hopes and sources are pouring onto ketchup. Ketchup eaters, in addition to meals technologists, can fulfill a few of their starvation for data by studying the research “Textural and rheological properties of sliceable ketchup“, printed within the journal Gels.

“There’s a lack of awareness on sliceable ketchup,” clarify the authors, who’re based mostly at three establishments in Iran: Islamic Azad College, Allameh Tabataba’i College and the Analysis Institute of Meals Science and Expertise.

For readers unversed within the area of sliceable sauces, they clarify: “Ketchup to be used together with sausages, as a closing product, will need to have a excessive viscosity, and by way of texture properties, it must be elastic and solid-state, and if chilly, it may be minimize and is sliceable like a sausage.” If profitable, this analysis may let ketchup be extra than simply an exterior sticky coating. The inside beckons.

The analysis aim is “to analyze the impact of gelling hydrocolloids on the bodily, textural, and rheological properties of ketchup and to develop a brand new formulation for sliceable ketchup and its mixed utility as a filler in meat merchandise reminiscent of sausages”.

So, we now have a rarity: cutting-edge ketchupry.

Ketchup on glass

Catching up on ketchup information that broke simply because the covid-19 pandemic was seizing everybody’s consideration, Suggestions finds that in 2020, on the Seventh European Seminar on Precision Optics Manufacturing in Teisnach, Germany, producers had been instructed about the advantages of placing ketchup on glass.

Max Schneckenburger and his colleagues on the Centre for Optical Applied sciences in Aalen, Germany, launched their friends to what, for some, was a brand new idea: “Excessive precision glass sprucing with ketchup“.

Their presentation defined the benefits of sprucing with a “non-conventional”, non-Newtonian fluid that “flows slowly underneath its personal weight and acts like a stable physique throughout brief intervals of stress as its viscosity will increase”.

Thus, ketchup, which in some circumstances behaves in non-Newtonian methods. They reward its behaviour: “Tomato ketchup reveals a time-dependent change in viscosity: the longer the ketchup undergoes shear stress, the decrease is its viscosity. Due to this fact, on this article, a brand new processing is put ahead to sprucing glass surfaces with ketchup containing micro-sized Ce2O. In addition to standard ketchup, curry ketchup and an natural product had been examined as properly.”

Schneckenburger’s workforce used an industrial robotic to information the sprucing head. This was, to one of the best of Suggestions’s data, the primary reported intentional occasion of robots on ketchup on glass.

Monetary smirks

You’re right in the event you suspect there are smirks contained in the monetary trade, deep behind the sombre, critical facades of buildings, enterprise fits and coiffures. Many high finance analysts, of their every day work, examine these smirks.

What’s a monetary smirk? The Choices Trade Council, which advises traders, explains, considerably, that “When mapping implied volatility ranges, the curve these factors create is usually recognized as both a ‘smile’ or a ‘smirk’ relying on the form created by the extent for out-of-the-money places and calls“.

In Suggestions’s unstable understanding of that idea, this type of smirk is a graphic, lopsided grin – one thing you see in plots when you have entry to sure varieties of monetary knowledge.

However virtually nobody exterior the trade sees these smirks.

That hiddenness resonates with an statement made half a century in the past by economist John Kenneth Galbraith concerning the chosen manner of finance executives. “No person,” mentioned Galbraith, “no person desires a humorous banker.”

Marc Abrahams created the Ig Nobel Prize ceremony and co-founded the journal Annals of Inconceivable Analysis. Earlier, he labored on uncommon methods to make use of computer systems. His web site is unbelievable.com
