    Archimedes discovered that if you add the volume of a cone and a sphere, you get the volume of their bounding cylinder. It’s one of the most beautiful results in 3D geometry! Learn more at math.fit/sphere-volume

    Cartographers always have to distort the surface of Earth in order to create a flat map. Notice how the same square on a map can have many different shapes and sizes in reality: math.fit/map-projection

    Isaac Newton was born 380 years ago. He in one of the greatest scientists in history: he discovered the laws of gravity and motion, invented calculus, built the first reflecting telescope, split white light into the visible spectrum, and so much more. mathigon.org/timeline/newton

    Different map projections distort the surface of Earth in different ways – which means that a square on a map is not always a square in real life! mathigon.org/go/map-project…

    BREAKING: Mathematicians have found an exact fraction that equals π, thereby disproving the long-standing conjecture that π is irrational. We now know that π = 1783366216531/567663097408. Learn more at mathigon.org/go/pi-fraction

    Emmy Noether was born 141 years ago #onthisday! She discovered how the symmetries of our universe correspond to conserved quantities in physics and thus can explain the most fundamental laws of nature. Learn more at mathigon.org/timeline/noeth…
