Dwarf planets
|
view preview
Not much of a believer in dwarf planets, but here's a cool schematic of some. In 2006 the organization responsible for classifying celestial bodies, the International Astronomical Union, decided that a new class of objects was needed. The solar system's erratic ninth planet, Pluto, was assigned to the new “dwarf planet” category along with four other bodies, all tinier than Earth’s moon. Some astronomers expect there may be as many as 50 dwarf planets in the solar system. Eris, the largest dwarf planet, is only slightly bigger than Pluto, at 1,445 miles in diameter (2,326 km).

|
view preview
A little over 30 years ago, a teenager named Jadav “Molai” Payeng began burying seeds along a barren sandbar near his birthplace in northern India’s Assam region to grow a refuge for wildlife.

Incredibly, the spot today hosts a sprawling 1,360 acre of jungle that Payeng planted single-handedly.

Babies are typically among the most vulnerable creatures in nature, but the fulmar has evolved a top notch defense system. Chicks also spit at their parents, who are immune to the effects of the oil.

How physics textbooks should teach electricity

Everything is easily explained with cartoons or a childrens book. That is why we do it for children, but apparently adults need it too, that is why we have comics and video games. I found the analogy portrayed above perfect in explaining how voltage and current relate.
