Re: What forces have shaped humanity most?
Disease and the various ways that we have dealt with disease has probably had the biggest impact on humanity. Until humanity started figuring methods of preventing and reducing the impact of disease, the world's population (for better or worse) would be nowhere near the present levels. We have developed a myriad of responses to preventing and treating disease ranging from things as simple as bathing on a regular basis to very complex technologies and surgical procedures. Without the medical procedures and technologies that have been developed over the ages, the human population would, most likely, be much, much less than it is today. Cities as we know them couldn't exist without some methods of treating and preventing disease.
Who is to blame for the U.S.'s dismal college graduation rate? "Radical" educator Dennis Littky has a hunch.
- COVID-19 has magnified the challenges that underserved communities face with regard to higher education, such as widening social inequality and sky-high tuition.
- At College Unbound, where I am president, we get to know students individually to understand what motivates them, so they can build a curriculum based on goals they want to achieve.
- My teaching mantra: Everything is permitted during COVID-19. Everything is permitted during COVID-19. Everything is permitted during COVID-19.
Meteorologists propose a stunning new explanation for the mysterious events in the Bermuda Triangle.
One of life's great mysteries, the Bermuda Triangle might have finally found an explanation. This strange region, that lies in the North Atlantic Ocean between Bermuda, Miami and San Juan, Puerto Rico, has been the presumed cause of dozens and dozens of mind-boggling disappearances of ships and planes.
What does it mean to "lead without authority"?
The planet that we are searching for is a little bit smaller and closer than we originally thought.
- Years ago, California Institute of Technology professor Konstantin Batygin was inspired to embark on a journey of discovering what lurked beyond Neptune. What he and his collaborator discovered was a strange field of debris.
- This field of debris exhibited a clustering of orbits, and something was keeping these orbits confined. The only plausible source would be the gravitational pull of an extra planet—Planet Nine.
- While Planet Nine hasn't been found directly, the pieces of the puzzle are coming together. And Batygin is confident we'll return to a nine-planet solar system within the next decade.
