When you see a small child try to fit into or on top of a doll-sized toy, youre likely to laugh. Thats exactly what three co-investigators of a new study initially did when their own toddlers attempted to fit into a toy car, a miniature room and a dolls crib.
Based on those personal observations, as well as their research as developmental psychologists interested in how young children understand symbols, the researchers from the University of Virginia, Northwestern University and the University of Illinois at Urbana-Champaign set out to understand why youngsters, who actually know better, make such dramatic mistakes about scale.
Not to worry, moms and dads. The study of 18- to 30-month-old children, published in the May 14 journal Science, found these kinds of errors -- scale errors -- to be common in this age group. Videotapes show many participants in the research seriously trying to slide down miniature slides, squeeze into tiny toy cars and sit in dollhouse chairs.

Physicists at the University of Basel are able to show for the first time how a single electron looks in an artificial atom. A newly developed method enables them to show the probability of an electron being present in a space. This allows improved control of electron spins, which could serve as the smallest information unit in a future quantum computer. The experiments were published in Physical Review Letters and the related theory in Physical Review B.
The spin of an electron is a promising candidate for use as the smallest information unit (qubit) of a quantum computer. Controlling and switching this spin or...

With a quantum coprocessor in the cloud, physicists from Innsbruck, Austria, open the door to the simulation of previously unsolvable problems in chemistry, materials research or high-energy physics. The research groups led by Rainer Blatt and Peter Zoller report in the journal Nature how they simulated particle physics phenomena on 20 quantum bits and how the quantum simulator self-verified the result for the first time.
Many scientists are currently working on investigating how quantum advantage can be exploited on hardware already available today. Three years ago, physicists...
'Quantum technologies' utilise the unique phenomena of quantum superposition and entanglement to encode and process information, with potentially profound benefits to a wide range of information technologies from communications to sensing and computing.
However a major challenge in developing these technologies is that the quantum phenomena are very fragile, and only a handful of physical systems have been...
Working group led by physicist Professor Ulrich Nowak at the University of Konstanz, in collaboration with a team of physicists from Johannes Gutenberg University Mainz, demonstrates how skyrmions can be used for the computer concepts of the future
When it comes to performing a calculation destined to arrive at an exact result, humans are hopelessly inferior to the computer. In other areas, humans are...
