Does a star undergo fusion or fission? What does nuclear binding energy mean and how do you know an atom has more than the others? Which of the following best describes nuclear fusion? A. It fuels nuclear power plants. B. It involves the splitting of one...
Green tech–or green technology–is an umbrella term that describes the use of technology and science to reduce human impacts on the natural environment. Green technology encompasses a wide area of scientific research, including energy, atmospheric science, agriculture, material science, and hydrology....
The gravitational constant (G) is a fundamental constant in physics that describes the strength of the gravitational force between two objects. It has a value of approximately 6.67430(15) x 10-11 Newtons (m2/kg2). Gravity and Everyday Objects The gravitational attraction between everyday objects...
I had a wonderful time, and seeing how she brought nanoscience concepts to a whole new context was truly inspiring. You can read more about Deidre’s process on her bloghere, where she describes her process and her time in Ireland. I enjoyed my collaboration with her so very much, and ...
This describes the time it takes for half the amount of any given radioactive material to decay, on average. For example, the half-life of plutonium-238 is 87.7 years, whereas uranium-238 has a half-life of 4.5 billion years. Splitting the atom Inside a fusion reactor. (Image credit: ...
Which statement best describes how heat energy is involved in changing water into steam? (a) Heat energy breaks the intermolecular forces holding molecules of water together. (b) Heat energy is released from intermolecular forc...
Describes, together with reference 18, how reporter genes that are linked to PREs are activated. In reference 18, activation of the reporter is artificially induced at high levels by heat shock. In reference 23, activation is achieved using developmental enhancers, which reveals a function for ...

This paper describes the present and the future of the energy sector in relation to the dominant and constantly evolving form of the global economic system. These considerations have their starting point in transformations of the energy sector in prosumer capitalism, which has dramatically changed the...
In other words, the virtual particle really is a popularized term that describes all manners of these disturbances between real particles. There are various ways to calculate the disturbances and one popular method is called the Feynman Diagram. The lines in the diagram are called “virtual p...
