What is Big Think?  

We are Big Idea Hunters…

We live in a time of information abundance, which far too many of us see as information overload. With the sum total of human knowledge, past and present, at our fingertips, we’re faced with a crisis of attention: which ideas should we engage with, and why? Big Think is an evolving roadmap to the best thinking on the planet — the ideas that can help you think flexibly and act decisively in a multivariate world.

A word about Big Ideas and Themes — The architecture of Big Think

Big ideas are lenses for envisioning the future. Every article and video on bigthink.com and on our learning platforms is based on an emerging “big idea” that is significant, widely relevant, and actionable. We’re sifting the noise for the questions and insights that have the power to change all of our lives, for decades to come. For example, reverse-engineering is a big idea in that the concept is increasingly useful across multiple disciplines, from education to nanotechnology.

Themes are the seven broad umbrellas under which we organize the hundreds of big ideas that populate Big Think. They include New World Order, Earth and Beyond, 21st Century Living, Going Mental, Extreme Biology, Power and Influence, and Inventing the Future.

The Brutal Physics of Football

“Brutality in playing a game should awaken the heartiest and most plainly shown contempt for the player guilty of it," said President Theodore Roosevelt in 1905, a year in which 18 young men died playing high school and college football.

The reform-minded Roosevelt's criticism led to sweeping changes in the rules, pushing the game of football closer to what it resembles today. Perhaps the signature innovation was the creation of the forward pass, a new concept at the time that would take a few years to be understood and perfected. 

What's the Big Idea?

It's not hard to see why many teams were slow to recognize the full potential of the forward pass. The challenge of throwing a tight spiral down the field and hitting your target with precision is a tricky one. As the ball travels through the air it follows a parabolic path that is influenced by multiple forces, such as gravity, and air resistance.

That is why best quarterbacks today have to intuitively understand how the forward pass works. They need to understand mechanics, the study of motion. Indeed, quarterbacks, kickers and even linemen who use their brute force to stop other bodies in motion all need to be intuitive physicists to succeed in this game. 

In the video below, Ainissa Ramirez, hailing from the birthplace of American football, Yale University, walks us through the major physics concepts at work in the sport.

What's the Significance?

Over 100 years ago, rules changes were introduced in order to make the game of football safer. Today we understand a lot more about head injuries than we did in the past. Responding to a rash of suicides by current and former players, further rules changes are being contemplated, such as replacing kickoffs. In the meantime, Ramirez argues that scientists need to do their part and design new protective equipment that will protect players from injuries, particularly head trauma.

Currently, she is writing a book on the science behind football with NYT bestselling author Allen St. John entitled Newton’s Football (Ballantine books). She is also the author of the new ebook Save our Science: How to Inspire a New Generation of Scientists, in which she advocates on how to humanize the sciences and introduces them into everyday life.
