The Earth has a crust, mantle, outer core and the inner core with each one getting hotter than the next. How come, over millions and millions of years, the heat that is at the center of the Earth hasn't conducted throughout the planet's material so that the entire planet is one even temperature?

This always bothered me because we all learn that temperature diffuses from high areas to low areas, yet the Earth's center is super hot while if you dig a one foot hole, the ground feels quite cold.

Seismologists interpret data from earthquakes and even simulate seismic activity with air guns and explosions, and their work has shown that the Earth's interior has different layers, some of which are easier for seismic waves to travel through than others. They can even tell us the densities of these layers.

Eva (Evita) Perón's legacy has inspired books, musicals, & films; she escaped rural Argentina, where there were few opportunities, & gained prominence as a radio & movie star; Eva's popularity among masses assisted her husband (Juan Perón) in his rise to power; using her radio show to tell people about her husband's policies, she helped him win the support of the working class (whom she affectionately called the descamisados (shirtless ones)); although she didn't hold a political office, she received the honorary title "Spiritual Leader of the Nation"; promising redistribution of wealth, labor reform, & national glory for Argentina, the Peróns threatened security of the wealthy who held power & gave hope to the poor; even in death, Eva Perón remained a controversial figure
Juan Perón had her body embalmed & had planned a large memorial to immortalize her, but his government was overthrown & he was sent into exile in 1955; at that time, the new government hid her body in an attempt to get rid of any evidence of the Perón years; her enemies buried her in a secret grave in Italy, where her body remained until the 1970s; her; her body was eventually returned to Argentina & laid to rest in a family cemetery in Buenos Aires
Her legacy has been subject to different interpretations over time; her supporters view her as a powerful female leader who championed of the poor & middle classes; those who opposed her said she manipulated the masses for her own ambitions; historians continue to sift through diary entries, political documents, & letters to unravel more about the mysteries of Eva Perón
Controversy surrounding Perón rule's reflective of political & social divisions within Latin America
Most nations in South America had gained their independence from Spain by the middle of the 19th century; throughout the remaining decades of that century & into the 20th, many South American nations struggled with political instability; governments rose & fell quickly & military coups d'etat were common; Juan Perón of Argentina is just one example of these political struggles
