Here we have a nice talk about how the mirror neurons stablished the basis of our society and social behaviour, given by Ramachandran.<br /><br /><a href="http://www.ted.com/talks/vs_ramachandran_the_neurons_that_shaped_civilization.html">VS Ramachandran: The neurons that shaped civilization | Video on TED.com</a><div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/1263469971778918758-8055895182602812263?l=ssiil.blogspot.com' alt='' /></div>Vincenthttp://www.blogger.com/profile/15825835692887540538noreply@blogger.com0tag:blogger.com,1999:blog-1263469971778918758.post-16693424525412806482010-01-19T03:41:00.000-08:002010-01-19T04:04:58.359-08:00Lof ot people think the economy is a non-understandable matter of study. Well, here I'll try to make the things easier for you and for me. <br /><br />My point today is that if we understand reality through the laws of physics we can also do the same through the laws of economics. When someone takes a course about physics the first thing he faces is Newton's ideas. In fact, if you think about it, almost the same laws can be applied in both fields of science.<br /><br />Newton basicly says:<br /><br />1) All bodies keep their state of motion if there is not a force operating over them<br />2) The underlying trend associated to space-time is speed<br /> v = ds/dt<br />3) Speed is an increasing function of the acceleration<br /> v = f(a)<br /><br />What about the economy? Here is my contribution:<br /><br />1) The asset values' don't change if the interest rate applied to those assets doesn't change<br /><br />2) The underlying trend of prices in time is profitability<br /> profitability = dp/dt<br /><br />3)Profitability is an increasing function of volatility(risk)<br /> profitability = f(risk)<div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/1263469971778918758-1669342452541280648?l=ssiil.blogspot.com' alt='' /></div>Vincenthttp://www.blogger.com/profile/15825835692887540538noreply@blogger.com0
