2 Lies, 1 Truth... Which one could it be...?

• • Neptune was never named Oceanus; it was named after the Roman god of the sea.

• Neptune was the first planet discovered using mathematical predictions.

• • Galileo observed Neptune in 1612 but mistook it for a star.

2 Lies, 1 Truth... Which one could it be...?

• • Albert Einstein discovered the expansion of the universe in 1929.

• • The expansion of the universe was confirmed by observing the redshift of distant galaxies.

• 1. The expansion of the universe means galaxies are moving faster than the speed of light.

2 Lies, 1 Truth... Which one could it be...?

• • Isaac Newton and Gottfried Wilhelm Leibniz independently developed calculus in the 17th century, but they published their works at the same time in 1670.

• • Newton’s method of fluxions was the first form of calculus, and he only shared it with a few scholars before publishing in 1704.

• 1. Leibniz’s notation for calculus, such as the integral and differential symbols, was adopted widely over Newton’s notation.

2 Lies,1 Truth...Which one could it be...?

• • Neptune was discovered after astronomers noticed it moving against the background stars.

• • Johann Galle and Heinrich d'Arrest used Le Verrier's predictions to locate Neptune just 1 degree from its predicted position.

• 1. Neptune was discovered using a microscope, not a telescope.

2 Lies, 1 Truth....which one could it be..?

• • The expansion of the universe was first observed by Albert Einstein through his theory of general relativity.

• • Edwin Hubble’s observation of redshift in distant galaxies showed that the universe is expanding.

• 1. The expansion of the universe was first confirmed by the discovery of cosmic microwave background radiation in 1910.

2 Lies,1 Truth.... which could it be?

• • Isaac Newton developed calculus first, but never published his work, keeping it private for years.

• • Gottfried Wilhelm Leibniz's notation for calculus was less efficient than Newton's and took decades to be widely adopted.

• 1. Newton and Leibniz had a public dispute over the invention of calculus, and both are now credited with its discovery.
