For patients covered by health insurance, out-of-pocket costs typically consist of a copay of $10-$50 or more, or coinsurance of 10-50% or more.
Johannes Stark. German physicist who won the Nobel Prize for Physics in 1919. In 1902 he predicted, correctly, that high-velocity rays of positive ions (canal rays) would demonstrate the Doppler effect, and in 1913 showed that a strong electric field can alter the wavelength of light emitted by atoms (the Stark effect).
For coining the Law of Photoelectric effect. And yes, not for E= mc2. The Nobel Prize in Physics 1921 was awarded to Albert Einstein for his services to Theoretical Physics, and especially for his discovery of the law of the photoelectric effect. Albert Einstein received his Nobel Prize one year later, in 1922. During the selection process in 1921, the Nobel Committee for Physics decided that none of the year's nominations met the criteria as outlined in the will of Alfred Nobel.
