Listen up: Our senior tech writer, Rick Broida, has spent the past two decades testing (and testing, and re-testing) hundreds of earbuds. So, when he's surprised by just how good a $40 pair ...
The mature alpha wave, at 10 waves per second, is firmly established by age 3. [14] The second occurrence of alpha wave activity is during REM sleep. As opposed to the awake form of alpha activity, this form is located in a frontal-central location in the brain. The purpose of alpha activity during REM sleep has yet to be fully understood.

A replica of an apparatus used by Geiger and Marsden to measure alpha particle scattering in a 1913 experiment. The Rutherford scattering experiments were a landmark series of experiments by which scientists learned that every atom has a nucleus where all of its positive charge and most of its mass is concentrated.

Alpha / ˈælfə / [1] (uppercase Α, lowercase α) [a] is the first letter of the Greek alphabet. In the system of Greek numerals, it has a value of one. Alpha is derived from the Phoenician letter aleph , which is the West Semitic word for "ox". [2] Letters that arose from alpha include the Latin letter A and the Cyrillic letter А.
Alpha particles have a net spin of zero. When produced in standard alpha radioactive decay, alpha particles generally have a kinetic energy of about 5 MeV and a velocity in the vicinity of 4% of the speed of light. They are a highly ionizing form of particle radiation, with low penetration depth (stopped by a few centimetres of air, or by the skin).
