Wilhelm R195182ntgen was a physicist, a man far more interested in understanding the building blocks of our universe than discovering medicines to cure the masses. In 1895, R195182ntgen performed a series of experiments
di Roberto Maragliano Se n'è parlato mai tanto e con accenti tanto unanimemente scandalizzati che c'è da sospettare che il caso sia stato costruito ad arte. Dei quattro concorrenti dell'Eredità (badate bene, non imberbi quindicenni, ma ben più grandicelli) tre non sanno collocare nel tempo Hitler e solo l'ultimo ci riesce, ma per mancanza di alternative. Indubbiamente, questo
Herman Daly considers the proper balance between "what for" and "how to" questions when selecting knowledge to transfer to the next generation.
An American and Canadian study looked at people's knowledge and willingness to learn about important complex issues such as the economy, energy consumption and the environment.
The structure of a London taxi driver's brain changes during the gruelling process of learning the quickest way around the capital, scans have revealed.
Structural MRIs of the brains of humans with extensive navigation experience, licensed London taxi drivers, were analyzed and compared with those of control subjects who did not drive taxis. The posterior hippocampi of taxi drivers were significantly larger relative to those of control subjects. A more anterior hippocampal region was larger in control subjects than in taxi drivers. Hippocampal volume correlated with the amount of time spent as a taxi driver (positively in the posterior and negatively in the anterior hippocampus). These data are in accordance with the idea that the posterior hippocampus stores a spatial representation of the environment and can expand regionally to accommodate elaboration of this representation in people with a high dependence on navigational skills. It seems that there is a capacity for local plastic change in the structure of the healthy adult human brain in response to environmental demands. * VBM, : voxel-based morphometry; ICV, : intracranial volume
