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).
Answer Einstein won the Nobel Prize for Physics in 1921 for his work on the photoelectric effect. From the Nobel.org website (see link to the left): for his services to Theoretical Physics, and especially for his discovery of the law of the photoelectric effect See the Related Questions and Web Links for more information.
