Theodore Gray Spell-with-elements

Image
Your Name in Elements (or Not) Your Name in Elements (or Not) A very silly webMathematica application by Theodore Gray Enter any string of letters below and webMathematica will attempt to write it in terms of chemical element abbreviations, if it's possible to do so. Since only certain one-and two-letter combinations exist as element abbreviations,only a fraction of all strings can be written that way. Good luck! The element symbol images are taken from my world-famous Periodic Table Table . Click on any letter to see information about and samples of that element. (Use only the letters a-z and space.) Output image size: 20 30 40 50 60 80 100 120 140 160 256 Abbreviations Only Full Element Tiles Sample Pictures Poster Sample Pictures (You may copy the HTML code for the images below to put this spelling on your own website, provided you keep the links to my website intact.)

Googol Song - Numberphile

There are ways to waste your time until departure. Like playing golf or reading Jeffrey Archer. Some people spend some proper afternoons on Wagner opera. But Friday by Rebecca Black is three minutes you won't get back! So I have tried to write a song that sets a record for how long a song can possibly go on. Are you ready, Matt? It goes, 1, Oh-oh-oh-oh-oh, Oh-oh-oh-oh-oh, Oh-oh-oh-oh-oh-oh-oh-oh-oh-oh. That's right, let's do it again! Come on! Oh-oh-oh-oh-oh, You can sing along if you like. Oh-oh-oh-oh-oh, Although not if you're in a library or on public transport. Oh-oh-oh-oh-oh-oh-oh-oh-oh. We need to get a few more of these done. How about we do three harmonies. That way we'll get it done a lot quicker! All right, here we go! Oh-oh-oh-oh-oh, Oh-oh-oh-oh-oh, Oh-oh-oh-oh-oh-oh-oh-oh-oh-oh. Nearly, hang on. Hang on. Phew. Well, bang the drum and play the victory bugle. What you did just there is sing a googol. *ding* One with a hundr

MathJax

Here are some examples of MathJax. $$\Delta L=\alpha L_0\Delta T$$ $$Q=mc\Delta T$$ $$Q=Lm$$ $$pV=nRT-NkT$$ $$dE=dQ-dW$$ $$e=\frac{W_{out}}{Q_{in}}$$ $$W=\int pdV$$ $$\Delta S=\int \frac{dQ}{T}$$ $$\epsilon \le 1-\frac{T_L}{T_H}$$ $$\frac{dQ}{dT}=kA\frac{T_H-T_C}{L}$$ $$\frac{Q_C}{W}=COP$$ $$F=\frac{Gm_{1}m_{2}}{r^{2}}$$ $$T^{2}=\frac{4\pi^{2}}{GM}r^3$$ $$U_g=-\frac{Gm_1m_2}{r}$$ $$x=\frac{-b\pm\sqrt{b^{2}-4ac}}{2a}$$ $$\mathfrak{MathJax\;test}$$ $$\mathtt{MathJax\;test}$$ $$\mathscr{MATHJAX\;TEST}$$ $$\mathcal{MATHJAX\;TEST}$$ Reference: click here
