How much does a neutron weigh? What is the de Broglie wavelength, (in nanometres), of an electron with a kinetic energy of 7.95 eV? How to calculate nuclear binding energy per nucleon How to calculate the energy of a photon in Joules ...
How does a proton synchrotron work? Proton A proton is an atomic particle which is positively charged within a nucleic of an atom. A proton is more stable since it has an equal charged electron to that of electrons. Moreover, protons have less mass in the nucleic, but they are more mass...
They made educated guesses about how much baryonic and dark matter might exist in the universe, then let the computer draw a map based on the information. The simulations showed dark matter as a weblike material interwoven with regular visible matter. In some places, the dark matter coalesced ...
Scientists led by Kelly Chipps of the Department of Energy’s Oak Ridge National Laboratory have successfully replicated a nuclear reaction that occurs on the surface of aneutron star. By using a unique gas jet target system, they have enhanced understanding of nuclear reactions that lead to the...
If a piece of aluminium consists of 6.02*10^{23} atoms, how much does it weigh? How do we know Mercury is made of iron and nickel if we have never sent anything to visit it? What is the chemistry of iron? How do I count sigma and pi bonds and how do you determi...

which enabled us to correlate numbers of visitors at each beach with quantities of debris. Finally, using travel time and expenses for each visitor to visit each beach, we modeled the relationship between where they chose to go to the beach, how much they spent to get there, and the cleanl...
(artificial intelligence)HAL 9000. Unfortunately, unlike the AI we are aware of, HAL had its own mind and ended up going on a killing spree. Another shocking but accurate depiction made in the movie was people’s extreme dependence on technology, which doesn’t sound much like fiction at ...
