A few days ago I was grading homework and I was pretty annoyed by students goofing up units and having their answers be many orders of magnitude off. One student’s homework was very interesting…
1. At the bottom of the page, he as the answer to part of the problem and the units are wrong. I [...]

I just stumbled across a paper in IEEE Transactions on Education titled, “Electrical engineering for the liberal arts: radio and its history.” Link is here. I have uploaded the paper to my server and you can find the paper here. The abstract is reproduced below.
A course for liberal arts students on the engineering and physics [...]

I finished grading my first homework assignment as a TA today. I e-mailed the professor with the homework mean and standard deviation and I indicated that I was pretty harsh when grading the homework. The professor e-mailed me back and said the mean was okay, but the following two sentences made me laugh.
If you find [...]

I think I will continue to sit in cash. I can sense that I am trying to force a trade and when I try to force a trade, it usually doesn’t turn out well.
I think we will rally into the end of the month; however, I am not willing to take that bet. If we [...]

I have this itch to go long on Monday. About a week ago, I blogged that the bias for the next two weeks would be upwards. The action didn’t pan out the way I expected and now there seems to be a better long entry than before.
I really like how the 800 level on the [...]

I am taking one class and homework is at least 10 hours a week + 4 hours of lecture.
I am also TAing one class. I need to write the homework solutions every week and do a lab section. That’s easily 10 hours a week.
Add the two up and it’s 24 hours a week. That’s three [...]

Fellow grad student: Hey, what’s that on your nose?
I have a big fat red pimple on my nose.
Me: Hey man, I am still young, okay?
Fellow grad student: Uh huh.
Me: You, on the other hand, are getting old.
Fellow grad student: Oh shit.

The monkey and the hunter problem is a classic problem posed in physics classes. It is reproduced below…

I just stumbled across an article that discusses why venom spitting snakes are so accurate and it’s pretty much the same reason as the solution to the money and the hunter problem.
“When we looked carefully at the data, [...]

I am usually very tight with my wallet and at the end of each month I am on average able to stash away an amount equal to one month’s rent (and that’s a long term average, taking into account every single expense down to the penny). However, this month I’ve had a lot of unavoidable [...]

The price action is starting to look eerily similar to what happened exactly one year ago, especially the financials. Huge dump in the morning, then after the day is over, all is well.
I had a mental note in my head the last few months to short WFC but I never got around to it. WFC [...]
