(9:48)</li>
<li><a href="https://www.youtube.com/watch?v=k7RM-ot2NWY">Linear combinations, span, and basis vectors</a> - "The fundamental vector concepts of span, linear combinations, linear dependence and bases all center on one surprisingly important operation: Scaling several vectors and adding them together." (9:55)</li>
<li><a href="https://www.youtube.com/watch?v=kYB8IZa5AuE">Linear transformations and matrices</a> - "Matrices can be thought of as transforming space, and understanding how this work is crucial for understanding many other ideas that follow in linear algebra." (10:54)</li>
<li><a href="https://www.youtube.com/watch?v=XkY2DOUCWMU">Matrix multiplication as composition</a> - "Multiplying two matrices represents applying one transformation after another. Many facts about matrix multiplication become much clearer once you digest this fact." (9:59)

Having talked about the relationship between matrices and transformations in the last two videos, this one extends those same concepts to three dimensions." (4:42)</li>
<li><a href="https://www.youtube.com/watch?v=Ip3X9LOh2dk">The determinant</a> - "The determinant of a linear transformation measures how much areas/volumes change during the transformation." (9:59)</li>
<li><a href="https://www.youtube.com/watch?v=uQhTuRlWMxw">Inverse matrices, column space and null space</a> - "How to think about linear systems of equations geometrically. The focus here is on gaining an intuition for the concepts of inverse matrices, column space, rank and null space, but the computation of those constructs is not discussed." (12:04)
<br> fn. <a href="https://www.youtube.com/watch?v=v8VSDg_WQlA">Nonsquare matrices as transformations between dimensions</a> - "Because people asked, this is a video briefly showing the geometric interpretation of non-square matrices as linear transformations that go between dimensions." (4:22)</li>
<li><a href="https://www.youtube.com/watch?v=LyGKycYT2v0">Dot products and duality</a> - "Dot products are a nice geometric tool for understanding projection. But now that we know about linear transformations, we can get a deeper feel for what's going on with the dot product, and the connection between its numerical computation and its geometric interpretation." (14:07)</li>
<li><a href="https://www.youtube.com/watch?v=BaM7OCEm3G0">Cross products</a> - "Dot products are a nice geometric tool for understanding projection.

Compass-and-straightedge construction (aka Euclidean construction) is a method of drawing precise geometric figures using only a compass and a straightedge (like a ruler without the markings). <a href="http://www.mathopenref.com/tocs/constructionstoc.html">MathOpenRef maintains a catalog of many common constructions</a>, each with an explanatory animation and a proof. <a href="https://www.youtube.com/watch?v=LBgIWQcC6lM">This YouTube video</a> demonstrates how to construct almost every <a href="https://en.wikipedia.org/wiki/Constructible_polygon">polygon that can be constructed using these methods</a>. Useful in many decorative arts for laying out figures and patterns, the methods can also be fun to watch, often resulting in an "aha!" moment when one sees how a particular construction is done.

First discovered in the seventeenth century by the Swiss mathematician Jacob Bernoulli when he was studying compound interest, e is now recognised as one of the most important and interesting numbers in mathematics. Roughly equal to 2.718, e is useful in studying many everyday situations, from personal savings to epidemics. It also features in Euler's Identity, sometimes described as the most beautiful equation ever written.

In the Bible's description of Solomon's temple it comes out as three, Archimedes calculated it to the equivalent of 14 decimal places and today's super computers have defined it with an extraordinary degree of accuracy to its first 1.4 trillion digits. It is the longest number in nature and we only need its first 32 figures to calculate the size of the known universe within the accuracy of one proton. We are talking about Pi, 3.14159 etc, the number which describes the ratio of a circle's diameter to its circumference. How has something so commonplace in nature been such a challenge for maths? And what does the oddly ubiquitous nature of Pi tell us about the hidden complexities of our world?

In the sixteenth century, a group of mathematicians in Bologna found a solution to a problem that had puzzled generations before them: a completely new kind of number. For more than a century this discovery was greeted with such scepticism that the great French thinker Rene Descartes dismissed it as an 'imaginary' number. The name stuck - but so did the numbers. Long dismissed as useless or even fictitious, the imaginary number i and its properties were first explored seriously in the eighteenth century. Today the imaginary numbers are in daily use by engineers, and are vital to our understanding of phenomena including electricity and radio waves.

<i>Futurama</i> has always been <a href="http://www.wired.com/entertainment/hollywood/magazine/15-12/ff_futurama_geekiestshow">a haven for geek humor</a>, but last week's episode <a href="http://theinfosphere.org/The_Prisoner_of_Benda">"The Prisoner of Benda"</a> pushed things to the next level. First hinted at in <a href="http://www.aps.org/publications/apsnews/201005/profiles.cfm">an American Physical Society interview</a> with showrunner David X. Cohen (<a href="http://www.metafilter.com/mefi/91995">previously</a>), staff writer and mathematics Ph.D. <a href="http://en.wikipedia.org/wiki/Ken_Keeler">Ken Keeler</a> devised <a href="http://www.geekosystem.com/futurama-prisoner-of-benda-theory/">a novel mathematical proof</a> based on <a href="http://en.wikipedia.org/wiki/Group_theory">group theory</a> to resolve the logic puzzle spawned by the episode's brain-swapping (but no backsies!) conceit. Curious how it works? Read the proof (<a href="http://static02.mediaite.com/geekosystem/uploads/2010/08/Prisoner-of-Benda-Theorem-on-Chalkboard.png">in the show</a> or in <a href="http://theinfosphere.org/The_Prisoner_of_Benda#The_proof">plain text</a>), then see it in action using <a href="http://img202.imageshack.us/img202/4002/inversion.png">this handy chart</a>.
