In your own words, what is the greenhouse effect?
I'm finding some opinions of individuals about the greenhouse effect. You as an individual reading this: in your own words, what is the greenhouse effect?
Example of placebo effect outside of medicine?
There have been numerous occasions in which I took a sip of drink A, thinking it was drink B, and tasted drink B. Scenario: John is convinced that wearing an orange jump suit will make him look slimmer. Everyone else sees that it does the opposite, but John thinks he looks great. Scenario: Jane is buying a new mattress. The salesman tells her that mattress A is the most comfortable mattress in the store, while mattress B is the least comfortable. When Jane tests out the mattresses, she agrees. All other customers who try out the mattresses report the opposite.
In your own words, describe the Doppler effect. Be sure to give at least one example of the Doppler effect?
The doppler effect has to do with how relative motion changes the apparent wavelength of a wave. For instance, a train coming towards you blows its whistle. The whistle sounds higher in pitch than it actually is because the waves are arriving at the speed of sound -minus- the speed of the train. As the train passes, its whistle sounds lower because now it's the speed of sound -plus- the speed of the train. Another example is 'blue shift' and 'red shift' in astronomy. A star or other light source traveling away from you, its light looks redder because the wavelength seems longer than it actually is. A light source moving towards you would look bluer.
Can the thing called placebo effect be proven that in fact it is placebo and not a miracle?
Using the first definition of a miracle, "a surprising and welcome event that is not explicable by natural or scientific laws" it is impossible to differentiate a miracle from a placebo (no concrete medical intervention) effect in medicine. The bottom line for a placebo effect is that the person healed themselves.If we look at the second definition of a miracle: "a highly improbable or extraordinary event, development, or accomplishment that brings very welcome consequences" then it is possible to differentiate a group of patients responding to placebo and someone with this sort of miraculous result. One example would be "miracle babies" who manage to survive even though they are born too premature to live. While one could argue that medical interventions are responsible, the same interventions are not sufficient for many other children, making the survival a highly improbable event, or a miracle by the second definition. Anyone arguing that these children are much more likely to survive because technology will save them despite very real life-threatening issues perpetuates the media hype around the few that do, creating "unrealistic expectations on the part of vulnerable families" (http://www.ncbi.nlm.nih.gov/pubm...) Living in hope and desperate for a miracle: NICU nurses perceptions of parental anguish.It should be noted that whether something is a placebo or a miracle is well defined within medicine. We have bureaus of doctors who specialize in making a differentiation between a placebo and a miracle healing. (Lourdes: A uniquely Catholic approach to medicine. ) There is a long list of approved miracles at Lourdes: Page on miraclehunter.com Whether these cures meet the second definition (improbable) or the first definition (divine intervention) is a matter of faith.
