&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;{{06-240/Navigation}}&lt;br /&gt;
&lt;br /&gt;
{{In Preparation}}&lt;br /&gt;
&lt;br /&gt;
* &amp;#039;&amp;#039;&amp;#039;To study the large, start with the small.&amp;#039;&amp;#039;&amp;#039;&lt;br /&gt;
&lt;br /&gt;
* &amp;#039;&amp;#039;&amp;#039;In small scales, every space is a vector space.&amp;#039;&amp;#039;&amp;#039;&lt;br /&gt;
** Indeed if you walk a mile east, a mile north, a mile west and a mile south, you&amp;#039;re back were you started, but if you fly a 1,000 miles east, a 1,000 miles north, a 1,000 miles west and a 1,000 miles south, you&amp;#039;re not back were you started (where will you be?).&lt;br /&gt;
&lt;br /&gt;
* &amp;#039;&amp;#039;&amp;#039;In small scales, every function is a linear function.&amp;#039;&amp;#039;&amp;#039;&lt;br /&gt;
&lt;br /&gt;
* &amp;#039;&amp;#039;&amp;#039;The world doesn&amp;#039;t come with coordinates.&amp;#039;&amp;#039;&amp;#039;&lt;br /&gt;
** Hence whenever we can we work without a basis, and when we do study bases, we study all of them.&lt;br /&gt;
&lt;br /&gt;
==Some Technical Remarks==&lt;br /&gt;
&lt;br /&gt;
===The Term Test===&lt;br /&gt;
&lt;br /&gt;
Our one and only Term Test is coming up. It will take place in class on Tuesday October 24 2006, starting promptly at 1:10PM and ending at 3:00PM sharp. It will consist of 4-5 questions (each may have several parts) on everything that we will have covered in class by October 18: the axiomatic definition of fields and vector spaces, &amp;lt;math&amp;gt;{\mathbb Z}/p&amp;lt;/math&amp;gt; and other examples, spans, linear combinations and linear equations, linear dependence and independence, bases, the replacement lemma and its consequences, a bit about linear transformations and a few smaller topics that we touched but don&amp;#039;t deserve their own headers. Note my comments from [[06-240/Homework Assignment 5]]:&lt;br /&gt;
&lt;br /&gt;
;Will there be &amp;quot;proof questions&amp;quot;?&lt;br /&gt;
:Sure. What else have we done so far?&lt;br /&gt;
;Do we need to know the proofs from class?&lt;br /&gt;
:Sure. There&amp;#039;s a reason why these proofs are in class to start with; if they weren&amp;#039;t valuable, we wouldn&amp;#039;t have covered them.&lt;br /&gt;
&lt;br /&gt;
Note also that there may be some computations, but nothing that will require a calculator. Note also that I may include some questions from the homework assignments verbatim or nearly verbatim.&lt;br /&gt;
&lt;br /&gt;
No electronic devices capable of displaying text or sounding speech will be allowed.&lt;br /&gt;
&lt;br /&gt;
===Extra Class Time===&lt;br /&gt;
&lt;br /&gt;
On Thursday October we will have a 2-hour class (1-3PM) to make up for the class time lost on the Term Test, and just one hour of tutorials (3-4PM) as no HW assignment is due on that week anyway.&lt;/div&gt;</summary>
