[1] Effect of Gravity on Gamma Radiation Recoil-free resonant absorption of the 14.4-keV γ ray in Fe57 has been employed to measure the effect of gravity over a 75-ft vertical path in the Jefferson Laboratory, in an improved...

[1] Optical Fiber Communications Optical fibers are used extensively for data transmission systems because of their dielectric nature and their large information‐carrying capacity. Network architectures using multiple wavelength channels per optical fiber are utilized...

[1] Generation of Magnetic Fields in the Radiation ERA It is shown that magnetic fields are generated during the radiation era of the early Universe in regions that have rotation. These fields are weak...

[1] Computers in physics education We start with an exposition of the situation of the physics education community at the beginning of the 21st century. We revise the findings of physics education research and...

Geothermal energy technology and current status: an overview Geothermal energy is the energy contained as heat in the Earth’s interior. This overview describes the internal structure of the Earth together with the heat transfer...

Non-CO2 greenhouse gases and climate change Earth’s climate is warming as a result of anthropogenic emissions of greenhouse gases, particularly carbon dioxide (CO2) from fossil fuel combustion. Anthropogenic emissions of non-CO2 greenhouse gases, such as...
