Aristotle believed in a geocentric model, with Earth at the center of the universe. Ptolemy further developed this idea with his geocentric model that included epicycles to explain planetary motion. Copernicus proposed a heliocentric model, with the Sun at the center of the solar system, challenging the geocentric view. Galileo's observations with a telescope provided evidence to support Copernicus's heliocentric model, leading to the acceptance of the heliocentric theory over the geocentric view.
When carbon is added to iron, the lattice structure transforms from pure iron's body-centered cubic to a face-centered cubic structure. This transformation results in the formation of steel, which has improved strength and hardness compared to pure iron.
When gasohol is added to gasoline, it increases the oxygen content in the fuel mixture. This helps in achieving a more complete combustion of the gasoline, leading to reduced emissions and potentially improved fuel efficiency. Gasohol is typically a blend of gasoline and ethanol, which is a renewable, bio-based fuel.
Cobalt was officially discovered as an element and added to the periodic table in the late 18th century, with its discovery commonly attributed to the Swedish chemist Georg Brandt in 1735.
Kepler's first law of planetary motion stated that the planets move in elliptical orbits with the Sun at one of the foci, contrary to Aristotle's and Copernicus's belief in circular paths. This deviation emphasized that orbits were not perfect circles, marking a significant departure from the established circular-centric views of the time.
16th century mathematician and astronomer Nicolaus Copernicus gets credit for popularizing the notion of a solar system with the Sun at the center (rather than the Earth at the center, as many had thought historically). The idea had been presented by others previously, perhaps the first being Aristarchus of Samos in the 3rd century BC., but Copernicus added detail and credibility and is often considered to have thus kicked off modern astronomy.
He added doors and improved the design.
Added a new column.
White flour has been improved with the addition of nutrients, white rice has been enriched with iron, and salt has added iodine.

I don't believe it does! The teeth were added after the discovery.
Because in an "all posting" concept, any answer can be improved or added to or even vandalized.

White flour, white rice, and salt have been improved with the addition of nutrients and minerals.
After. The stamp act was added in 1765 and the sugar act was improved in 1764.
alot of the rules have been changed and some rules have been added. the equipment has also improved (ex. there are alloy and aluminum bats). the popularity of softball in the US. has increased greatly, also.
It wasn't much of a "discovery", but in increasing health concerns in the U.S. & elsewhere, it was added to the curriculum.
