An atomic clock uses atoms to help maintain high precision in its measurements of the quartz vibrations. The length of a second is measured by the frequency of light released by specific atoms, which is same throughout the universe. But atoms in current clocks can be sensitive to external mag...
Perhaps the matter of which the resurrection body will be composed will not have separate atoms and molecules (and so will be indestructible). Perhaps our bodies will not have separate organs and systems, but the body as a whole, or the whole soul in the whole body, will perform all of ...
“InAtoms and Ashes,Ukrainian historian Serhii Plokhy, author of a brilliant book on Chernobyl, looks at six nuclear disasters around the world—starting with the testing of a hydrogen bomb in Bikini Atoll in 1954 and ending with Fukushima—to see what lessons can be learned from them. As ci...
The author is very thoughtful about explaining the science in a simple way, without being patronising, leaving a lot of space for the colourful pictures. Young readers learn plenty of facts about shells and their diverse environments from coral reefs to the abyss, but What a Shell Can Tell ...
8.This would explain why isotopes can smell different: their vibration frequencies are changed if the atoms are heavier.Turin's mechanism, says Marshall Stoneham of the UCL team, is more like swipe-card identification than a key fitting a lock. 9.Vibration-assisted electron tunnelling can undou...
Material Benefits Resulting from the Polymer Structure Silicones are characterized by a fully saturated backbone of alternating silicon and oxygen atoms. The Si-O links in the chain have an exceptionally high bond energy of 451 kJ/mol. By comparison, C-C links have a bond energy of 352 kJ/...
 With phenomenal scientific facts – such as the 4,900 quadrillion atoms per second that must be selected from our food and precisely assembled into our red blood cells to keep us alive, the book looks at atoms as building blocks in the hands of a skilled and intelligent Builder....
Bonus Facts: The traditional “five senses” model (sight, hearing, touch, smell, and taste) is credited to Aristotle One such method for testing whether humans have magnetoception is by placing a strong magnetic field near a person and then disorienting them. Results have shown that people...

(aged 12 to 14) was the idea of considering dissolution and changes of state as a chemical reaction. It must be clear that the substances remain the same during a physical change, whereas during a chemical change a break and formation of new bonds between atoms occurs, which enables the ...
