		<title>Why math?</title>
		<link>http://www.teamliquid.net/blogs/viewblog.php?topic_id=304497</link>
		<author>Muirhead</author>
		<description>A very kind person, who I respect very deeply, posed a question: Is it a valuable use of time to study theoretical math today?  Does it help humanity?  Are there better ways to use one's time?

There are many types of math, and I can't understand most well enough to even approach the question.  But I can try a little, at least with the sort of math I'm interested in...

Argument 1: Much mat...</description>

She wants to curl up in its ventral sacs and fly across the country.  But it's too slow :(</description>

		<description>Why do people believe in God?  Not why, as in, why do they disbelieve in atheism, but why as in why do they ask themselves THE question at all?

I think they are looking for purpose in their existence.  Why seek purpose?  I think because they do not know how they should behave, how they should act and think and BE.  To determine what actions to take, what thoughts to make, they feel they must...</description>

He has about 20 battlecruisers hovering over his mined out island on scrapstation.  The island is full of turrets.  Turrets apparently kill 3/3 voidrays and interceptors.  I got a mothership in by suiciding 200/200 voidrays but my recall lost to BCs.

I have infinite money, since he only had 2 bases all game long.

TL, YOU'RE MY ONLY HOPE.

		<title>Help identifying old game?</title>
		<link>http://www.teamliquid.net/blogs/viewblog.php?topic_id=105092</link>
		<author>Muirhead</author>
		<description>I'm trying to remember the name of a fairly old game I played (from around the time of Starcraft).  I know it's not much information to go by, but basically it was a single-player RTS/RPG hybrid game.  The defining feature was that you could build units or shops etc. but you couldn't control the units you built.  They would walk around and fight on their own.  It was set in a fantasy setting.  ...</description>

		<author>Muirhead</author>
		<description>Please PM me if you are interested in participating in CSL at MIT.  I want to gather some data on who is interested.

Include your best iccup rank in your PM.  For reference, if you are C-/C level or above we could probably use you for the team.  Of course, regardless of your rank CSL can be a great way to meet other Starcraft lovers.</description>

		<description>Ok it's my turn to post a shameless homework help thread :(.  In the past I have been really surprised/impressed by the background of folks on this site so I'm hoping you guys can help me out ^^.

I'm trying to write complete solutions to the problems in Ramakrishnan and Valenza's book.  The problems are generally approachable but given the sheer volume of questions I know I'm going to get st...</description>

		<description>Disclaimer: These numbers are not supposed to have any real significance

Suppose you are playing an RTS on some ladder.  Assume everyone has equal skill levels, so we are simply speaking about build order advantages.  Your standard, &quot;safe&quot; build order against a different race gives you an 80% chance of having a 60% chance to win a game.  During the other 20% of your games you lose ...</description>

		<title>Yet Another Math Puzzle</title>

		<author>Muirhead</author>
		<description>While I work on gondolin's interesting problem, here's something along the lines of the problems that have been posted.

Definition: A three-legged spider is a the union of three line segments, all meeting at a single point.  For example, a T is a three-legged spider.

Question: Can you fit uncountably many three-legged spiders in the plane?  If not, can you prove it is impossible?

Blergh... I spent 5 consecutive Mondays working through the night to beat people in this thing, and now after the 6th all-nighter I lose it all by some ridiculously slim margin :/

		<title>College and a math problem</title>

		<author>Muirhead</author>
		<description>Harvard waitlisted me... It seems they rejected or waitlisted many of the top US mathematics students of the year (based on math competitions and Westinghouse).  9 of us are going to MIT :).  I can't help but think Harvard shot itself in the foot.

Here's a problem easier than the last few I've posted: 
Given a 1000x1000 chessboard, n squares are colored red and the rest are colored blue.  I...</description>

		<title>APM and a math problem</title>

		<author>Muirhead</author>
		<description>I'm now a solid D+ on iccup but my APM has never been over 90 in a game I've won.  I thought it would get better with time but I've been playing for a few months now and it stays put at ~80.  I feel I would win a lot more if I were able to move even a little bit faster.  Maybe I should just stick to math... the USAMO is only a month away.

Speaking of math, does there exist a countable abelia...</description>

		<description>It seems I barely made it into the top 100.  I'm happy to make it that far as a high school student, but I can't help feeling I would have placed much higher if I hadn't screwed up A1.  Anyone else from teamliquid do well?

EDIT: For Slithe, my favorite problem of the ones I solved:

Let n be a positive integer.  Find the number of pairs of polynomials (P(x),Q(x)) with real coefficients suc...</description>

Let M be a connected, compact, smooth manifold without boundary.  Let V denote the (real) vector space of all smooth functions from M into the real line.  Call a subspace H of V invariant if whenever h is in H and...</description>

		<title>Solving the quartic equation</title>
		<link>http://www.teamliquid.net/blogs/viewblog.php?topic_id=66841</link>
		<author>Muirhead</author>
		<description>So it seems I got a 138 on the AMC 12A, missing two early problems because I can't add without a calculator :/.  Did anyone else from teamliquid take it?

I thought I would devote this entry to some interesting mathematics rather than a problem.

All of us know how to solve quadratic equations, and if you know Galois theory you know it is impossible to solve a quintic.  Recently I saw a ver...</description>

		<title>An interesting geometry problem</title>
		<link>http://www.teamliquid.net/blogs/viewblog.php?topic_id=65798</link>
		<author>Muirhead</author>
		<description>This one has many solutions, a few of which are rather amazing in my opinion.

Suppose O,V, and W are three circles in the plane, none of which intersect each other and all of which have different radii.

Given any two of the three circles, there will be exactly four lines tangent to both circles.  Two of those lines will not intersect the segment connecting the centers of the two circles. ...</description>
