Introduction</title><p>So, the aim of this work is to derive the golden ratio connected to Lorentz trans- formation. Usually the golden ratio is derived from the a rectangle [<xref ref-type="bibr" rid="scirp.71561-ref1">1</xref>] but book [<xref ref-type="bibr" rid="scirp.71561-ref2">2</xref>] derives the golden ratio from a right-angled triangle. This makes possible to connect Lorentz transformation with the golden ratio. The Lorentz factor formula can be the easiest explained from the right-angled triangle. The formula <inline-formula><inline-graphic xlink:href="http://html.scirp.org/file/8-7502894x3.png" xlink:type="simple"/></inline-formula> is in fact the formula of one of the right-angled triangle side:</p><p>1) <inline-formula><inline-graphic xlink:href="http://html.scirp.org/file/8-7502894x4.png" xlink:type="simple"/></inline-formula></p><p>It can be seen from this formula also that “c” is the hypotenuse of the right-angled triangle. At the same time “<inline-formula><inline-graphic xlink:href="http://html.scirp.org/file/8-7502894x5.png" xlink:type="simple"/></inline-formula>” is one criterion of Lorentz factor formula as well. That means, that the hypotenuse of the right-angled triangle is “c”, the other sides is “v” and<inline-formula><inline-graphic xlink:href="http://html.scirp.org/file/8-7502894x6.png" xlink:type="simple"/></inline-formula>. This allows that from so defined right-angled triangle to explain the formula of Lorentz transformation too and the golden ratio formula as well. For the derivation of the equations high school mathematics is used. That’s the reason why the equations are more transparent and easier to understand because they are simply.</p></sec><sec id="s2"><title>2. We Introduce First the (t'/t) Formula</title><p>The derivation of Lorentz transformation can be found at the end of the book marked by [<xref ref-type="bibr" rid="scirp.71561-ref3">3</xref>] in the Appendix I. The derivation of Lorentz transformation equations starts from the fact that we measure two light-rays move face each other, in a standing and in a moving coordinate system. So the travelled distance of the light-ray in the standing coordinate system is<inline-formula><inline-graphic xlink:href="http://html.scirp.org/file/8-7502894x7.png" xlink:type="simple"/></inline-formula>. Naturally in the movable coordinate system the travelled distance of the light-ray is<inline-formula><inline-graphic xlink:href="http://html.scirp.org/file/8-7502894x8.png" xlink:type="simple"/></inline-formula>. Here it can be seen that Lorentz’s starting point were a few assumptions, (see [<xref ref-type="bibr" rid="scirp.71561-ref3">3</xref>] Appendix I) and from these simple assumptions got the formula named after him. After that Einstein substituted in the Lorentz trans- formation equation<inline-formula><inline-graphic xlink:href="http://html.scirp.org/file/8-7502894x9.png" xlink:type="simple"/></inline-formula>, the equation of<inline-formula><inline-graphic xlink:href="http://html.scirp.org/file/8-7502894x10.png" xlink:type="simple"/></inline-formula>.
