Started reading "Drawing on the Right Side of the Brain."  There's a lot of bullshit and pseudoscience, but there are solid points in it.  As part of the recommended exercises, they say that the reader should draw three items before doing any of the lessons.  This helps establish a baseline against which to compare.  This is one of the good ideas.  The first items I drew were as suggested: a self portrait in a mirror, a person from memory, and my hand.  I will not upload the person for both confidentiality's sake and because it is terrible.

First illustration of the year.

Someone told me today, "Fuck your blog.  It needs more pictures of cats."

Brilliant!

Progress: 9/1000 problems.  I expected to hit 150 today.  Let's see what can happen tonight.

I believe strongly in the rational, an act which to a select few may seem self-contradictory.  I believe strongly in reason, the absence of belief.  I believe strongly in logic, contrary to itself.  The whole of my morality stems from a set of three very small principles.  These can be embellished and extended by means of logical operators and simple arguments.  I believe the following:

  1. Be decent to everyone, even if they are not decent to you.
  2. Be excellent to those who are excellent to you.
  3. In situations of moral ambiguity, err on the side of freedom so that people can apply their own moral values.

It is with this background in mind that I offer for consideration, the Twelve Virtues of Rationality.  There are no words of praise that do justice to its poetry, but our efforts to follow even in part would bestow on the world great benefit.

Hummus is Mad Delicious and Crazy Easy

  • 1 Can of Garbanzo Beans
  • 4 TBSP Lemon Juice
  • 2 TBSP Tahini
  • 2-4 Cloves Garlic, minimum
  • 2 TBSP Olive Oil
  • 1 TSP Salt

Open and drain garbanzo beans. Do not rinse.
Add everything to the food processor and maul that shit.
Chill like a motherfucker. Tell your hummus, "Bitch, be cool."
Eat with pita bread.

Hummus was invented in the year 2525 by the Norse god Odin.  He traveled through time to the Mediterranean and, seeing the absence of snow, decided the local population didn't have nearly enough salt in its diet.  Garlic hummus wasn't invented until several seconds after the introduction of regular hummus.  Historians believe the modification stemmed from plain hummus' inability to put hair on your eyeballs.  Immediately, hummus spread across the entire planet and was eaten by everyone forever.  The end.

Auxiliary status update: Behind schedule.  7/1000 Math.

Happy New Year to all.  The last batch of math problems is physics themed and taken from Physics for Scientists and Engineers.  The image is reproduced here.

A suspended cube (m2) attached by ideal pulley to another cube (m1).

Problem description:

Given the mass of m1 is 7kg and the mass of m2 is 5kg, calculate the forward acceleration of m1.  The coefficient of kinetic friction between m1 and the surface is 0.54.  Assume the mass m1 is already moving.  (Disregard static friction.)

Solution:

We begin by calculating the force exerted on m2.  Force = mass * acceleration.  We know acceleration due to gravity is 9.81 m/s2.  F_m2 = 5kg * 9.81m/s^2 leaves us with 49.05N.  Now we should calculate the force on m1.  For starters, we need to calculate the force that m1 exerts on the table.  This will give us the surface normal force which, when combined with the coefficient of friction, will provide the 'resistance' to forward motion.  F_m1 = 7kg * 9.81m/s^2 = 68.67N.  Multiply by the coefficient of friction and we end up with 0.54*68.67N = 37.0818N.  Again, this 37N force will act against the pull from m2.  49.05N - 37.0818N = 11.9682N.  Now that we have the sum of forces on m1, we can calculate the acceleration.  F = ma.  11.9682N = 7kg * a.  11.9682N/7kg = 1.709742857 m/s^2

Other problems were thematically similar, and dealt with determining the coefficient of sliding friction and calculating the velocity required to keep water in a bucket as it spun in circles.
