Iron the Red Atom Molecule

Iron the Red Atom Molecule (to the tune of "Rudolph The Red-Nosed Reindeer")
There was Cobalt and Argon and Carbon and Fluorine Silver and Boron and Neon and Bromine But do you recall the most famous element of all? Iron the red atom molecule had a very shiny orbital And if you ever saw him You'd enjoy his magnetic glow All of the other molecules used to laugh and call him Ferrum They never let poor Iron join in any reaction games. Then one inert Chemistry eve Santa came to say Iron with your orbital so bright won't you catalyze the reaction tonight? Then how the atoms reacted and combined in twos and threes Iron the red atom molecule you'll go down in Chemistry! 

All Numbers Equal

Theorem: All numbers are equal.
Proof: Choose arbitrary a and b, and let t = a + b. Then a + b = t(a + b)(a - b) = t(a - b)a^2 - b^2 = ta - tba^2 - ta = b^2 - tba^2 - ta + (t^2)/4 = b^2 - tb + (t^2)/4(a - t/2)^2 = (b - t/2)^2a - t/2 = b - t/2a = b
So all numbers are the same, and math is pointless.

Reason to Shine

You are so beautiful you give the sun reason to shine. Of course, the sun shines by burning hydrogen into helium in its core.
