Created the geocentric universe theory. Which was the basis of our understanding of how celestial objects move for over a thousand years.

Building off Ptolemey’s theory, he created the Heliocentric solar-system theory. Launching modern astronomy and setting off a scientific revolution.

Created the first telescope, helping prove Copernicus’s Heliocentric theory. He used the telescope to discover the moons of Jupiter.

Developed the three basic laws of motion and the theory of universal gravity. Laid the foundation of our understanding of current physics.

Studied finches in the Galapagos islands, ultimately resulting in the creation of the natural selection theory. Pathing the way for future evolutionary research.

Created the periodic table, which helps sort elements by their increasing atomic mass. The table even had space for elements yet to be discovered.

# data[].attributes.body
Helped us better understand the atom - that energy was within some atoms resulting in radioactivity. Also discovered 2 new elements.

Discovered 2400 Cepheid variable stars. Cepheid variables have luminosity periods. Using that, she estimated the distance of stars and proved that there are other galaxies.

Discovered that continents move. Saw that continents lined up together on a map, and have geological similarities. Did not have enough evidence to prove it.

(He built off of Henrietta Leavitt's discovery)

Discovered that the universe was larger than originally believed and that the Universe is expanding. Using the observation of redshift from distant galaxies being stretched.

Was very skilled in X-ray diffraction. Created photo 51, demonstrating the double helix. Crick and Watson could not have done what they did without her.

X-ray crystallography was used to better understand DNA. Franklin took a clear photo, and Watson built a model. He and Crick discovered the double helix.

Palaeoanthropologists who proved that humans are related to apes. Had found skulls and bones in Africa that were similar to apes.

Explored the ocean floor, discovering mid-ocean-ridges. He fathered the sea-floor spreading theory. Added on to the Pangea and Wegener’s theory.

She found that chimpanzees are much more intelligent than what was originally thought. They use tools. Also protected them - Funded the Jane Goodall Institute.

Discovered that an asteroid killed the dinosaurs, by observing rock’s sedimentary layers. He proved scientists wrong as they believed that change could only happen slowly.
