Let's try, for our New Year's resolutions, to do something not only to benefit ourselves, but all of the English-speaking world. Let's try to collectively learn the correct usages of homonyms and apostrophes.
Grammar! Eeee!Collapse )

The Rules:
1. Grab the nearest book to you.
2. Open the book to page 123.
3. Find the fifth sentence.
4. Post the text of the next 4 sentences on your blog along with these instructions.
5. Don't you dare dig for that "cool" or "intellectual" book in your closet! I know you were thinking about it! Just pick up whatever is closest.

I had two books the same distance away, in different directions, so y'all get both.

"Anyone who is not a half-wit can learn all there is to know of painting, by standing in front of paintings and looking at them. What was the use, then, of being an apprentice?"
"This flea is a magnificent piece of--"
"It is not art but a higher form of bungling," Hooke demurred.

From Neal Stephenson's Quicksilver.


We next consider the boundary conditions and assume that the string has fixed endpoints

ro(0)=ro(l)=0 (25.23)

The ordinary differential equation (25.20) evidently has the following solution that satisfies the first of the boundary conditions (25.23)

ro(x)=(2/l*sigma)^(1/2) sin (kx) (25.24)

where the choice of normalization will be discussed shortly. The second boundary condition in Eq. (25.23) can be satisfied only for certain special values of k. These eigenvalues are given by

k_n= (n*pi)/l n=1,2,...,inf (25.25)

and the normal-mode frequencies are related to these values through Eq. (25.21)

omega_n=(n*pi)/l * c (25.26)

The first law of thermodynamics is you do not talk about thermodynamics.

The second law of thermodynamics is you DO NOT talk about thermodynamics!

Reading the Song of Susannah. Bought the Song of Roland. Looked up the Song of Roland on E2. The Song of Roland is only tangentially related to Childe Roland to the Dark Tower Came. Said poem is based off of Shakespeare's line in King Lear,

"Child Roland to the dark tower came,
His word was still, "Fie, fo, and fum;
I smell the blood of a British man."

Which referenced not the son of Charlemagne, but probably a Scottish hero named Rowland.

Now, of course I am also doing Linear Algebra at the same time, looking up orthonormal basis on the Internet. And, of course, Todd Rowland wrote the information on MathWorld.

1. Stop talking about politics for a moment or two.
2. Post a reasonably-sized picture in your LJ, NOT under a cut tag, of something pleasant, such as a fluffy bunny, or mad fat stacks of cash, or the answers to a physics test. Something that has NOTHING TO DO WITH POLITICS.
3. Include these instructions, and share the love.

Problem 23.

Calculus 0wnz0rs me; I shall not pass.

He maketh me to grate my teeth. He leadeth me toward the wrong solution.

He crusheth my soul. He teacheth me nothing that I can comprehend

Yea though I read through my textbook and check all my work, I fear the integral: for j00 pwn me. Thy div and thy curl they terrify me.

Thou preparest a table before me of integrals I will never use. I anointest my exams with blood; I have writer's cramp.

Surely vectors and derivatives will haunt me for all the days of my life, and I will dream of exams of calculus forever.
