If spread out evenly, this would mean every college would have one lead specialist in physics. I assume the remainder of any teaching of physics is carried out either by part-timers or by those with qualifications that contain elements of the subject. There does seem to be a question ...
That depends on what you mean by "life." Fuse/Thinkstock Key Takeaways Common requirements for Earth-based life include being carbon-based, requiring water, using energy and having the ability to grow or reproduce. Life necessitates water for many chemical reactions and energy in the form ...
(WIMPs), which are about as well understood as their catch-all name implies. WIMPs don't even seem to interact with each other through anything more than gravity, meaning dark matter does not fuse to form larger or more complex molecules and remains in a simple—and highly diffuse—gas-...
The switch pictured here is mounted under the car's fuse access panel. Photo courtesy Directed Electronics The switch that makes this work is like the mechanism that controls the light in your refrigerator. When the door is closed, it presses in a small, spring-activated button or lever,...
A U.S. lab has successfully sparked a fusion reaction that released more energy than went into it. But there’s still a long way to go toward fusion as a clean energy source.

In EEPROM, data is stored by charging or discharging the floating gates of individual memory cells through electrical programming. Unlike EPROM, EEPROM does not require exposure to UV light for erasure; instead, a high-voltage signal is applied to selectively remove the stored charge from the floa...
“Ideas have retained some of the properties of organisms,” he wrote. “Like them, they tend to perpetuate their structure and to breed; they too can fuse, recombine, segregate their content; indeed they too can evolve, and in this evolution selection must surely play an important role.”...
What is the function of fuse or circuit breaker in a circuit? What is a closed circuit? Which unit of electricity does the work in the circuit? What is a circuit that has only one path? What are the types and components of electric circuits? What is the current in a 660V circui...
