The Bohr theory explains the spectrum of hydrogen by proposing that electrons orbit the nucleus in fixed, quantized energy levels. When an electron transitions between these levels, it absorbs or emits energy in the form of photons, leading to specific wavelengths of light. This results in the distinct spectral lines observed in hydrogen's emission and absorption spectra, corresponding to the differences in energy between the quantized orbits. By calculating these energy differences, Bohr was able to accurately predict the wavelengths of the spectral lines observed experimentally.

The first person to openly reject Ptolemy's geocentric theory was Nicolaus Copernicus. In his work "De revolutionibus orbium coelestium," published in 1543, he proposed a heliocentric model, stating that the Sun, rather than the Earth, is at the center of the universe, with the planets, including Earth, orbiting around it. This revolutionary idea challenged the long-held belief in an Earth-centered cosmos and laid the groundwork for modern astronomy.

Alexander Fleming, who gained fame in the early 20th century, is best known for his discovery of penicillin in 1928, which revolutionized medicine by introducing antibiotics.

Fleming's contributions not only advanced medical science but also transformed public health practices in the decades that followed.

Kepler's theories of motion, known as Kepler's Laws of Planetary Motion, describe the orbits of planets around the Sun. The first law states that planets move in elliptical orbits with the Sun at one focus. The second law, or the law of areas, indicates that a line segment joining a planet and the Sun sweeps out equal areas during equal intervals of time, meaning planets move faster when closer to the Sun. The third law establishes a relationship between the time a planet takes to orbit the Sun and its average distance from the Sun, quantifying that the square of the orbital period is proportional to the cube of the semi-major axis of its orbit.
