Quarky & Quaysoo's Turbo Science was reviewed in the Oppenheim Toy Portfolio Guide Book where it was described as a set of "fun science problems". Noting that the problems orient toward "energy, chemistry, magnetism, and air and water pressure", the authors assessed the game as best suited for children aged 9 years and older.
The following is a list of notable unsolved problems grouped into broad areas of physics. [1]Some of the major unsolved problems in physics are theoretical, meaning that existing theories seem incapable of explaining a certain observed phenomenon or experimental result.
The electromagnetic fields of light are not affected by traveling through static electric or magnetic fields in a linear medium such as a vacuum. However, in nonlinear media, such as some crystals, interactions can occur between light and static electric and magnetic fields—these interactions include the Faraday effect and the Kerr effect ...

December 13, 2024 at 2:43 PM (Reuters) -The Louisiana Department of Health said on Friday it has detected the first presumptive positive human case of H5N1 bird flu infection in the U.S. state.
The former sense is sometimes called luminous efficacy of radiation, [4] and the latter luminous efficacy of a light source [5] or overall luminous efficacy. [ 6 ] [ 7 ] Not all wavelengths of light are equally visible, or equally effective at stimulating human vision, due to the spectral sensitivity of the human eye ; radiation in the infrared ...

In 1848–49, Hippolyte Fizeau determined the speed of light using an intense light source at the bell tower of his father's holiday home in Suresnes, and a mirror 8,633 meters away on Montmartre. [2] The light source was interrupted by a rotating cogwheel with 720 notches that could be rotated at a variable speed several times a second.
