(PhysOrg.com) -- The most accurate timekeepers in the world are atomic clocks, which tell time based on the absorption of a very specific and unchanging microwave frequency, which induces electrons in an atom to “jump” ...
Even after nine months soaking in the womb, a newborn's skin is smooth - unlike an adult's in the bath. While occupying a watery, warm environment, the newborn manages to develop a skin fully equipped to protect it in a cold, ...
