In the way magic eye posters simultaneously hide and reveal the main point of the picture, new research suggests that children might well be asking more than their simply-worded questions seem to indicate.
Normally, adults assume that when children ask, "What is this?" in reference to an object, they are seeking merely a name--some kind of label to help differentiate the elements of their rapidly burgeoning universes. However, a new study explored the possibility that children posing such a question might actually be seeking the object’s function, not simply its name. These findings by Swarthmore College researchers Deborah Kemler Nelson, Morghan Holt and Louisa Chan Egan will be published in the June issue of Psychological Science, a journal of the American Psychological Society.
The study separated two-, three-, and four-year-olds into two groups, and allowed the children in each group to inquire about unfamiliar artifacts. In one group, questions were answered with the name of the object; in the other, its function was provided. Regardless of age, children were inclined to follow up with supplemental questions about an object when they were told only its name. However, the children given thorough, functional information seemed more satisfied with the response.

In a recent publication in the renowned journal Optica, scientists of Leibniz-Institute of Photonic Technology (Leibniz IPHT) in Jena showed that they can accurately control the optical properties of liquid-core fiber lasers and therefore their spectral band width by temperature and pressure tuning.
Already last year, the researchers provided experimental proof of a new dynamic of hybrid solitons– temporally and spectrally stationary light waves resulting...

Moving into its fourth decade, AchemAsia is setting out for new horizons: The International Expo and Innovation Forum for Sustainable Chemical Production will take place from 21-23 May 2019 in Shanghai, China. With an updated event profile, the eleventh edition focusses on topics that are especially relevant for the Chinese process industry, putting a strong emphasis on sustainability and innovation.
Founded in 1989 as a spin-off of ACHEMA to cater to the needs of China’s then developing industry, AchemAsia has since grown into a platform where the latest...
The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.
Modern production technologies in the automobile industry must become more flexible in order to fulfil individual customer requirements.
An international team of scientists has discovered a new way to transfer image information through multimodal fibers with almost no distortion - even if the fiber is bent. The results of the study, to which scientist from the Leibniz-Institute of Photonic Technology Jena (Leibniz IPHT) contributed, were published on 6thJune in the highly-cited journal Physical Review Letters.
Endoscopes allow doctors to see into a patient’s body like through a keyhole. Typically, the images are transmitted via a bundle of several hundreds of optical...
