Artillery fire on both sides was constant this. Entire villages were wiped off the map and. Never before had so many soldiers been killed in such a limited area. Or Dead Mans Hill was the scene of particularly bitter fighting. At the end of the Battle One Of The Hills Two summits was ten meters lower than it was before. Served as a laboratory for testing new weapons the german army fired poison gas in shells here for the first time. This allowed for more accurate targeting. The effect on french ...

Ionizing radiation can damage living tissue in the human body. It strips away electrons from atoms breaks some chemical bonds.

Have you ever wondered how scientists can fully understand the atom without putting their own biases aside? Picture this: a seminal experiment that not only challenged but also laid the groundwork for the modern atom-to-the-other-atom understanding. Rutherford's Experiment opened a Pandora's box of discoveries about the atomic world.In a nutshell, the Rutherford's Experiment used cutting-edge

Sensors in smoke detectors monitor how particles in the air affect a flow of current to the battery Garrett Aitken/iStock via Getty ImagesEditor’s note: MVS Chandrashekhar is a professor of electrical engineering at the University of South Carolina. In this interview, he explains how smoke detectors work and why they sometimes sound an alarm for what seems like no reason. Why do smoke detector alarms go off even when there’s no smoke? The most likely reason smoke detectors go off u...

Turns out, a fallout shelter can be just about anywhere — if you’re meeting the right conditions.

Alpha particle therapy, such as diffusing alpha-emitters radiation therapy (DaRT) and targeted alpha-particle therapy (TAT), exploits the short range and high linear energy transfer (LET) of alpha particles to destroy cancer cells locally with minimal damage to surrounding healthy cells. Dosimetry for DaRT and TAT is challenging, as their radiation sources produce mixed radiation fields of α particles, β particles and γ rays. There is currently no dosimeter for real-time in vivo dosimetry of ...

IMAGINE an atom: like a miniature solar system with the nucleus in the centre and electrons orbiting around like planets.  Although the picture is familiar, analogies like this can mislead. New research published in Science last week by a team largely based in Darmstadt, Germany, emphasises that the atom is far stranger than our simple images. We still have much to learn about its inner citadel: the nucleus.  The discovery of the atomic nucleus is a little over a century old. Earlier ideas ab...

>> yeah. >> so for example, im not saying this is the answer, im just saying for example. there is a company trying to do very, very hot fusion. this is not cold fusion. this is very hot fusion. since i was a kid, since i was in engineering school, people have been trying to do fusion by shooting a beam of hydrons. that has an extra nutron. it has not worked. these people have boron and hydrogen. >> you just happened to have that laying there. >> i just have it. to produce the three alpha partic...

Iraqi tanks didnt stand a chance against these sophisticated munitions dug rocky and his unit worked to selvage us armored vehicles that had been contaminated through exposure to depleted uranium we collected it all together we buried a lot in the desert and we shipped a lot back to the united states have been took over three years of cleanup. later some allied soldiers began showing symptoms of what would later be called gulf war syndrome. the depleted uranium becomes dangerous only after the m...
