**The World’s Most Beautiful Equations**From top:

Math is Beautiful, math is the absolute truth and that makes it beautiful. Mathematicians even go so far as calling it an art form.

mathematics, rightly viewed, possesses not only truth, but supreme beauty — a beauty cold and austere, like that of sculpture, without appeal to any part of our weaker nature, without the gorgeous trappings of painting or music, yet sublimely pure, and capable of a stern perfection such as only the greatest art can show - Bertrand Russel

One of the most amazing equations, in my opinion, is the Lorentz factor,

Virtually all of the mathematics behind Einsteins theory or special relativity can be reduced back to this one, simple equation. basically, these few lines describe exactly what happens when you travel close to the speed of light, and the fact that it is as simple and short as it is, is beautiful.

Help! I am so incredibly terrible at balancing chemical equations and I'm in honors science and its caused me to drop from a 96% to an 81% any advice or tips??

A lot of people have trouble with balancing equations, so I’m going to explain how I teach them in the hope it might help a few people. I don’t know if it’ll work for you, but I teach my pupils how to balance them using Lego. Let’s use a displacement reaction as an example:

Obviously, you can’t change any of the formulae, so I’ve boxed them off as a reminder. You can only put numbers **in front of** the different elements or compounds in the equation to balance it. To start with allocate a different coloured lego to each element in the equation. I’m going to use blue for aluminium, green for copper, yellow for sulfur and red for oxygen. I’m also going to use circles because I’m too lazy to draw lego. Just, I don’t know, pretend they’re Lego:

Now, that’s already looking a little more complicated. But remember, all we want to do is ensure we’ve got the same number of each element (each colour circle) on either side of the dotted line. You can see at the moment we’re short of one aluminium (blue), two sulfurs (yellow), and quite a few oxygens (red)! Since aluminium’s the easiest one to solve, let’s do that first - you just need one more blue circle on the left, so if we put a two in front of Al, that solves it:

We also need another two sulfurs. We can achieve that by putting a 3 in front of CuSO4. However, we’ve got to bear in mind that doing this multiplies all the elements in that compound by three. So, as well as ending up with three sulfurs, we’ll also get three coppers and twelve oxygens:

That turns out to have been quite useful, since we’ve now got the right number of sulfurs and oxygens. However, we’ve now got three coppers on the left, when we only have one on the right. That’s easy to fix with a three in front of copper:

And there we have our balanced equation - you can see we’ve now got the exact right number of each element (or each coloured circle/lego). Hope that method helps you!

Look at **Albert Einstein** working in his **Theory of General Relativity** in Zurich:

Einstein’s search for general relativity spanned eight years, 1907-1915. Some periods were quiet and some were more intense. The moments when the great transition occurred, came sometime between the late summer of 1912, when Einstein moved from Prague to Zurich, and early 1913.

Another crucial age-old mystery has been solved: **What are the physics and mathematics behind the ponytail?**

Once pondered by Leonardo Da Vinci, British scientists at University of Cambridge have used what they call a “Rapunzel Number,” a ratio of information regarding gravity and length, to find an exact “Ponytail Shape Equation.” Their equation as a whole takes in account the stiffness and waviness of individual hairs, gravity, and how a “bundle of hair is swelled by the outward pressure which arises from collisions between the component hairs.”

In a statement, Professor Raymond Goldstein said:

That determines whether the ponytail looks like a fan or whether it arcs over and becomes nearly vertical at the bottom… Our findings extend some central paradigms in statistical physics and show how they can be used to solve a problem that has puzzled scientists and artists ever since Leonardo da Vinci remarked on the fluid-like streamlines of hair in his notebooks 500 years ago.

So, why did we want to know about ponytail physics? These equations could help the understanding of the structure of materials made up of random fibers, such as wool and fur, in addition to aiding those in the computer graphics and animation industry, where it has proven difficult to properly replicate human hair.
