About

I am a newcomer in this Wiki Contributor's World, though I am used to be over the Wikipedia. I am from Bangladesh.

Here are some simple mathematical equations. They are written using LaTeX.

• Hubble's Law :

                $V=H_{0}D\,$
                ${\frac {dD}{dt}}={\frac {\dot {a}}{a}}\,D\,$

• Newton's Law :

                $F_{\text{Total, External}}=m\,a\,$

• Solution of a quadratic equation

                $ax^{2}+bx+c\,=0\,$
                $x_{1,2}\,={\frac {-b\pm {\sqrt {b^{2}-4ac}}}{2a}}\,$

Etymology

My user name is Lubdhaka. It is the Sanskrit cum Bangla [Bangla লুব্ধক] name of the star Sirius, the brightest star in the night sky, in the constellation of Canis Major.
