It's been 400 years of thinking the heart is a pump — isn't it time for a change? Let's look at the evidence, the history, and the way forward.
In an age where science is constantly overturning what we thought we knew about the body, and new theories come out every day trying to explain new phenomena, one theory remains unchallenged. Since 1628, when Harvey published his seminal text on the circulation of blood, we have believed more or less the same thing about the heart. But what if the heart isn't a pump at all? And what if it's time that we update Harvey's ideas? In order to move forward, Dr. James Mohebali tries to lead us through the evidence, and see what the shortcomings of our current understanding are. On the way, we critically examine the practice of empiricism & the idea of conspiracy theories, and discover the implications of and problems associated with holding on tight to our current beliefs. Between Galen, Harvey, Descartes, McDonalds hamburgers, and a father's responsibility to his family, the search for truth leads us to some difficult and deep questions, and hopefully a few answers.
