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

Centrifugal force is not the only fictitious force to rear its ugly head in a rotating frame of reference. There's another one called the Coriolis force that affects moving things and it makes things even weirder. Video Links: Centrifugal Force Does NOT Exist! http://youtu.be/zHpAifN_2Sw

Why Does The Placebo Effect Work?
A placebo is a phony drug used to test the efficacy of real drugs in clinical trials… but here’s the weird part. Sometimes, placebos can make patients better. How? Why? Learn more at HowStuffWorks.com: http://science.howstuffworks.com/life/placebo-effect.htm Share on Facebook: http://goo

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

The Coriolis effect says that anytime you're rotating—whether it's on a playground toy or your home planet—objects moving in straight lines will appear to curve. This bizarre phenomenon affects many things, from the paths of missiles to the formation of hurricanes. You may have heard that

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
