&amp;#039;&amp;#039;&amp;#039;Alejandro Martínez Castillo&amp;#039;&amp;#039;&amp;#039; (born 1962 in Salto, Uruguay) is an electrical engineer and independent physics author. He graduated in electrical engineering from the University of Campinas (UNICAMP), Brazil, in 1989, and is the author of the book &amp;#039;&amp;#039;A New Light in Physics&amp;#039;&amp;#039;. He is listed in &amp;#039;&amp;#039;[[The Worldwide List of Dissident Scientists]]&amp;#039;&amp;#039;.&lt;br /&gt;
&lt;br /&gt;
==Work==&lt;br /&gt;
In &amp;#039;&amp;#039;A New Light in Physics&amp;#039;&amp;#039;, Martínez Castillo advances his own theories of light, elementary particles and the fundamental forces of nature. He proposes the existence of two more elementary constituents, which he calls the &amp;quot;positrin&amp;quot; and the &amp;quot;negatrin&amp;quot;, and argues that the known electric (Coulomb), magnetic and gravitational forces — together with a further &amp;quot;ultimate force&amp;quot; that prevents these constituents from being destroyed in collisions — arise from them. In his account the ordinary atomic particles are combinations of positrins and negatrins, and he posits an absolute classical reference space.&lt;br /&gt;
&lt;br /&gt;
He revisits classic experiments — among them those of Kaufmann, Fizeau, Hertz, Davisson–Germer, Sagnac and Feynman — and reinterprets them in an attempt to resolve wave–particle duality. These ideas are proposed by the author outside the framework of accepted physics.&lt;br /&gt;
