Carol Jean L. Moseke Frost (born March 8, 1945 in Cedar Rapids, Nebraska) is a female track and field athlete from the United States, competing in the discus throw. She represented her native country at the 1968 Summer Olympics, and won the gold medal in the women's discus throw event at the 1967 Pan American Games in Winnipeg, Manitoba, Canada. She was a four-time champion in the women's discus at the USA Outdoor Track and Field Championships. Following the Olympics, Moseke returned to Nebraska and married Larry Frost, a former Nebraska football player, and from 1977–80, Carol Frost coached the Huskers' women's track and field team. Among her first athletes was Merlene Ottey, who won the first AIAW Championship for the Nebraska program. Ottey went on to win the most women's Olympic track and field medals ever. Later, she got out of coaching track to coach football alongside her husband and eventually coached her sons Steve Frost and Scott Frost during their days as high school stars at Wood River High School. Steve, a former college lineman and long snapper at Colorado State and Stanford, is the public address announcer for Stanford Football home games, a job he's done for over 20 years. Scott quarterbacked the 1997 Nebraska Cornhuskers football team to a national championship, before becoming offensive coordinator at theUniversity of Oregon, and later becoming the head coach at the University of Nebraska. As Carol Frost, she has continued to compete into the Masters age groups. She holds the current American record in the W65, W70, and W75 Shot Put; the W60, W65, W70, and W75 records in the Discus; and the W65, W70, and W75 World record in the Javelin.

The planet Neptune was mathematically predicted before it was directly observed. With a prediction by Urbain Le Verrier, telescopic observations confirming the existence of a major planet were made on the night of September 23–24, 1846, at the Berlin Observatory, by astronomer Johann Gottfried Galle (assisted by Heinrich Louis d'Arrest), working from Le Verrier's calculations. It was a sensational moment of 19th-century science, and dramatic confirmation of Newtonian gravitational theory. In François Arago's apt phrase, Le Verrier had discovered a planet "with the point of his pen". In retrospect, after it was discovered, it turned out it had been observed many times before but not recognized, and there were others who made various calculations about its location which did not lead to its observation. By 1847, the planet Uranus had completed nearly one full orbit since its discovery by William Herschel in 1781, and astronomers had detected a series of irregularities in its path that could not be entirely explained by Newton's law of universal gravitation. These irregularities could, however, be resolved if the gravity of a farther, unknown planet were disturbing its path around the Sun. In 1845, astronomers Urbain Le Verrier in Paris and John Couch Adams in Cambridge separately began calculations to determine the nature and position of such a planet. Le Verrier's success also led to a tense international dispute over priority, because shortly after the discovery George Airy, at the time British Astronomer Royal, announced that Adams had also predicted the discovery of the planet. Nevertheless, the Royal Society awarded Le Verrier the Copley medal in 1846 for his achievement, without mention of Adams. The Royal Society, however, also awarded Adams the Copley medal in 1848. The discovery of Neptune led to the discovery of its moon, Triton, by William Lassell just seventeen days later.

The use of energy is considered sustainable if it meets the needs of the present without compromising the needs of future generations. Definitions of sustainable energy typically include environmental aspects such as greenhouse gas emissions, and social and economic aspects such as energy poverty. Renewable energy sources such as wind, hydroelectric power, solar, and geothermal energy are generally far more sustainable than fossil fuel sources. However, some renewable energy projects, such as the clearing of forests to produce biofuels, can cause severe environmental damage. The role of non-renewable energy sources has been controversial. Nuclear power is a low-carbon source and has a safety record comparable to wind and solar, but its sustainability has been debated because of concerns about nuclear proliferation, radioactive waste and accidents. Switching from coal to natural gas has environmental benefits but may lead to a delay in switching to more sustainable options. Carbon capture and storage technology can be built into power plants to remove their carbon dioxide emissions, but is expensive and has seldom been implemented. The global energy system, which is 85% based on fossil fuels, is responsible for over 70% of the greenhouse gas emissions that cause climate change. More than 750 million people lack access to electricity and over 2.6 billion rely on polluting fuels such as wood or charcoal to cook. Reducing greenhouse gas emissions to levels consistent with the Paris Agreement will require a system-wide transformation of the way energy is produced, distributed, stored, and consumed. As the burning of fossil fuels and biomass is a major contributor to air pollution, which causes an estimated 7 million deaths each year, the transition to a low-carbon energy system would have strong co-benefits for human health. Pathways exist to provide universal access to electricity and clean cooking technologies in ways that are compatible with climate goals, while bringing major health and economic benefits to developing countries. Climate change mitigation scenarios describe pathways in which the world would rapidly shift to low-emission methods of generating electricity, rely less on burning fuels for energy, and rely more on electricity instead. For some energy-intensive technologies and processes that are difficult to electrify, many scenarios describe a growing role for hydrogen fuel produced from low-emission energy sources. To accommodate larger shares of variable renewable energy, electrical grids require flexibility through infrastructure such as energy storage. To make deep cuts in emissions, infrastructure and technologies that use energy, such as buildings and transport systems, would need to be modified to use clean forms of energy and also to conserve energy. Some critical technologies for eliminating energy-related greenhouse gas emissions are not yet mature. Wind and solar energy sources generated 8.5% of worldwide electricity in 2019, a share that has grown rapidly while costs have fallen and are projected to continue falling. The IPCC estimates that 2.5% of world GDP would need to be invested in the energy system each year between 2016 and 2035 to limit global warming to 1.5 °C (2.7 °F). Well-designed government policies that promote energy system transformation can lower greenhouse gas emissions and improve air quality simultaneously, and in many cases can also increase energy security. Policy approaches include carbon-pricing, renewable portfolio standards, phase-outs of fossil fuel subsidies, the development of infrastructure to support electrification and sustainable transport, and funding research, development, and demonstration of new clean energy technologies. uuu bhai maro
