it.euronews.com Un generatore in miniatura, posto nelle suole delle scarpe, in grado di produrre energia elettrica mentre si cammina, alimentando dispositivi mobili. Lo stanno studiando scienziati del Lawrence Berkeley National Laboratory, in California. L'idea è quella di sfruttare l'energia meccanica, prodotta dal movimento, usando una sottile pellicola di virus benigni che creano elettricità . Il film, inserito in una calzatura, potrebbe alimentare un dispositivo mobile, ma potrebbe anche essere impiantanto nel corpo umano per alimentare un pacemaker. Gli scienziati hanno creato il primo generatore che funziona utilizzando le proprietà piezoelettriche di un materiale biologico. "Questo - spiega Seung-Wuk Lee, scienziato presso la divisione di Bioscienze - è il primo nanogeneratore basato sulle proprietà piezoelettiche dei virus. Se schiacciamo l'apparecchio, se applichiamo della forza e poi rilasciamo, l'elettricità si accende e si spegne.» Produrre elettricità sfruttando il movimento per esempio dei piedi. Questo semplice dispositivo riesce a produre un quarto della potenza di una batteria tripla A. I risultati della ricerca sono stati pubblicati a maggio sulla rivista Nature Nanotechnology. "Nel prossimo futuro - aggiunge Seung-Wuk Lee - crediamo di poter sviluppare generatori elettrici personali che incamerino tutto il movimento meccanico della nostra vita quotidiana come camminare, fare jogging, scrivere su una tastiera. Quel tipo di movimento meccanico che può ...
Have you ever wondered about those kids who consistently win prizes at the science fair? What is it that makes them so special? Sure most people say it's because they're smart, and they can come up with projects no one else would have thought of, but the truth is you can be just like them! The one thing these kids have that you don't is that they probably know the secrets behind the best science fair projects, and those secrets are easily learned!
First secret is to stick to the rules, but learn how to bend them. Study the rules of your science fair so you know what you can and cannot do. Next, see if there are any loopholes in the rules. The truth of the matter is that rules for science fairs can often be stretched to your advantage. After you fully understand the basic rules, you can choose one of the best science fair projects you can think of and mold the rules around your project, making sure that your project follows all the rules. For example, there's a ru le that the project has to be able to withstand some weather conditions, and the project you thought of uses cardboard. If that's the case, use plywood or plastic to create your project, making it qualify and well within the rules!
The second, and possibly most important secret is to study the old best science fair projects. Take projects from about six years ago or older. If the first place winner of that year received a lot of acclaim that people still remember it, choose the second place winner. Find out what they did and if they had any recommendations for future experimenters. Sometimes, following the recommendations of past experiments and tweaking the experiment up a bit can give you the edge that the old winner didn't have to make it to first place! If it's stated in your rules that past projects cannot be entered, try focusing on a different aspect of the project or completely changing the materials. Coming up with a different design or presentation flow can a lso throw people off.
For the third secret, remember to be neat. It's very seldom that the best science fair projects in all science fairs are messy. Being able to create a project that teaches and demonstrates a science concept that is neat and straightforward will always score extra points with the judges. Also having neat and easy to read data and graphs will be a plus with the judges. Your presentation has to be smooth flowing as well. Prepare a script for yourself and practice it several times. This will show the judges that your topic is well learned.
Finally, choose something relevant. Coming up with a project that can help the environment or can make life easier for a certain social group is always a winner. Social relevance is something a lot of good science projects forget to touch on, but you will find that many of the best science fair projects all talk about something socially relevant. So come up with something that will show the judges that you're aware of the needs of the environment and society, and you're a shoo-in for top prize!
More Secrets of the Best Science Fair Projects TopicsQuestion by : What branch of science is most closely related to wave functions and Schrodinger's cat? As far as I know they're both related to physics in some way. Course I may be wrong, so correct me if you may. Also, if you do know which belongs in which, may you explain this branch of science to me? Thank you for whoever answers. Best answer for What branch of science is most closely related to wave functions and Schrodinger's cat?:
Answer by David Geelan
They're both parts of quantum physics. Quantum deals with phenomena at very small sizes, down around the size of photons and electrons. Very briefly, objects at this sizes have a 'wave nature', and their behaviour can be studied by solving their wave functions. The way electrons move in a hydrogen atom, for example, are quite well understood in terms of their wave functions, and indeed the 'electron orbitals' in all atoms are quantum phenomena. Schrodinger's cat was a famous thought experiment about the role of observation in quantum situations: it turns out that there are differences that occur in the wave functions of particles depending on whether their position (for example) is measured or not. I could probably explain more, but hopefully this gives you some places to start. If you take a physics major at university you will study *lots* of quantum.
