This 16 months old baby was in a car crash with his mother and sister. The impact was severe and he suffered internal decapitation: his spine was dislocated, the head separated from the neck (only the bones were separated, the spinal cord inside and the skin and flesh around were still attached).
As you might recall from math class, pi is the ratio of a circle’s circumference to its diameter. This irrational number—approximately 3.14159—shows up quite frequently in many mathematical applications, including geometry and trigonometry.
The first attempts to calculate pi can be traced back to ancient Babylonians, who calculated the area of a circle as three times the square of its radius, making the value of pi equal to 3. One Babylonian tablet indicated they got as close as 3.125 and later calculations by the ancient Egyptians (ca. 1650 BC) approximated pi as 3.1605.
The number today is celebrated around the world on March 14, which when written out numerically is 3.14.
On YouTube, Michael Blake decided to pay tribute to Pi. By assigning a number to each musical note, he was able to create a composition by playing out the digits of pi. View the video of his piece below.
The vast majority of objects out there in the universe are pretty big…moons, planets, stars, galaxies, so it can be difficult sometimes to get your head round their actual size.
With the huge continent of North America dwarfed by Jupiter’s storms, the universe seems an even larger place. In the other direction, Mars looks so much more human-scaled.
This is how North America looks like in relation to Jupiter, one of the giant planets:
But this is what it lookslike on Mars:
