Okorokov effect

The Okorokov effect (Russian: эффект Окорокова) or resonant coherent excitation, occurs when heavy ions move in crystals under channeling conditions. V. Okorokov predicted this effect in 1965 and it was first observed by Sheldon Datz in 1978. (Wikipedia).

Teach Astronomy - Doppler Effect

http://www.teachastronomy.com/ The Doppler Effect is the shift of wavelength or frequency of a source of waves due to the motion of that source of waves. Doppler Effect is most familiar in terms of sound waves. As a source of sound, such as a siren, approaches you, the pitch or frequency

AWESOME Physics demonstration. Coriolis effect (explained)!!!

The Coriolis effect refers to the apparent deflection of objects (such as airplanes, wind, missiles, and ocean currents) moving in a straight path relative to the Earth's surface. Its strength is proportional to the speed of the Earth's rotation at different latitudes. For example, a plane

How the Doppler effect works

Imagine you are standing in the middle of a road and a car is coming towards you. The driver sounds the horn so that nothing unpleasant happens, and you hear the horn very loudly, at a high pitch, and step out of the way. However, as the car moves away from you, the sound of the horn seems

Why Should we REPORT Effect Size for Hypothesis Tests (16-10)

Significance tells us that the effect was likely not due to chance. Effect size is a standardized measure of how large the effect was. Cohen’s d is the most commonly used measure of effect size for t tests. There are three statistical reasons to report an effect size: if generalization is

Cohen’s d Effect Size for t Tests (10-7)

An effect size is “a standardized measure of the size of an effect”. Unlike p values, effect sizes can be objectively compared to determine whether a treatment had any practical usefulness. Cohen’s d is the most commonly used measure of effect size for t tests. This video makes three point
