Valentine’s Day is quite close and I thought I could give some of you some ideas for presents. Even though mathematicians are not into this celebration, I can assure you that if you know what gift to take they will be as excited as everyone else. You might think that a math related gift might be to much, but I assure you we love it a lot. So here are some suggestions which might work quite good:

1. Cards: these don’t have to be bought and most of the time it is quite hard to find some that represent exactly what you want, but just take a piece of paper and some colorful pencils or pens and write what ever you have in your mind, but don’t forget to put just a drop of mathematics in it. Here are some of my favorite ideas:

2. T-shirts: if you believe that a card is not enough and you want something a little more different, a t-shirt could be the best idea. Here are some great ideas of T-shirts and a hoodie idea for those that live in countries where T-shirts for Valentine’s Day is not appropriate (click the image if you want to see how you could buy them) :

There could other ideas, such as books or cups, plates, etc; but I thought this is enough as a list of ideas. For me something minimal is better than a lot of things. Personal I would love to receive just a small card ^_^ Anyway, hope you will have a great Valentine’s Day full of mathematics and love.

Have a great day. You can find me on Facebook,  Tumblr,  Google+,  Twitter,  Instagram  and  WeHeartIt. I will try to post there as often as possible.

Don’t forget that maths is everywhere! Enjoy! ~LThMath~

Valentine’s Day for Mathematicians Valentine’s Day is quite close and I thought I could give some of you some ideas for presents.

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.

DIY Science Valentine’s Day Cards Printables from Evil Mad Scientist. I look forward to Evil Mad Scientist’s Valentine’s Day cards every year. This year they are featuring hearts, arrows and love in their equations. You can download all 18 cards at the Evil Mad Scientist link.

Below are the 2013 and 2014 Science Valentine Printables. 2013 was equation heavy and 2014 was symbol heavy.

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.
