2 years ago, I messed up some sort of question around Multiple Slit Interference. Finally getting around to blogging about it, so I'll just give my brief understanding of what the main things to think about with it are. The more slits you add, the more smaller interferences in between, such that aside from the brightest points, other semi-bright points are visible. For n slights, these are number n-2.

After messing up a discussion with a researcher from Bloomberg, I figured it'd be good to post a couple of basic ML things to remember here.
First, the assumption of Naive Bayes Classifiers is independence of random variables (allowing distribution of individual probabilities), not anything about the discrete space.
Secondly, in attempting to choose between logistic regression and a decision tree in a binary classification problem, correlation should push towards the former. This is indicated by the rank of the data matrix, particularly if it is low relative to the number of features and (less) the number of datapoints.

It has been a very long time since I've written here. Since I doubt very many people read it, I use it as a sort of journal, where I can write more personal things. On the other hand, my school blog is read by many people at my school. It can be accessed at achalana.evolutionofinstruction.org.
Before I actually start writing the short post I intend to, I want to acknowledge that it is very unfortunate that I didn't know who Freddie Mercury was when I wrote my last post. I've had a lot more exposure to the rock scene over the past year, and now obviously know who Freddie Mercury and Queen are.
My post today has been sparked by an email conversation regarding a change of school policy that has been deemed my responsibility by the Student Government as the head of the Advertising Committee. My email was written majorly in spite and anger after becoming increasingly emotional about the topic. While this hasn't yet resulted in significant consequences in me, it is steadily destroying my reputation. While it was a clear way of demanding change, it was offensive to certain people, and has the potential to cause significant problems in the way of the administration's receptiveness to Student Government. The moral of the story is that a large amount of importance must be placed on preventing yourself from being offensive to people, especially in such mediums as email, where your words could end up in someone's hands who you didn't expect them to.

I had a bit of time today, and I decided that I wanted to write another one of my blog entries about the trending topics on Yahoo! that I used to write in my Yahoo! Blog. When I decided to go look for my blog on Yahoo! Pulse, I found that that feature had been discontinued. I suppose I was disappointed, but I quite promptly decided I would come here and write. There were a few people who would read my entries there, so maybe they'll come here.
Anyway, today was the last day of summer for me: my school starts tomorrow. I slept in for probably the last time in a while, since the grind will start back up tomorrow with my 6:00 alarm. My sister, my dad and I went to Lowe's to pick up some light bulbs for the landscape lights that we discovered had bad bulbs in our yard while we were reparing them yesterday. We also meant to pick up Seona's friends, Lynzley and Locksley on the way back home to play with her. When we got there, we found out that their little sister, Lexeigh, also wanted to come, but we only had a 5-seater car, so I ended up walking home. I haven't done much else as of the time that I am writing this blog entry.
The top trending topic today is Freddie Mercury, who I had honestly never heard up until I looked him up. Apparently, he is a famous rock star that died twenty years ago from bronchopneumonia caused by AIDS, and the Google logo today celebrates his 65th birthday. Since I don't know much else about him, I think I'm going to stop there.
Second place was Amanda Knox, who I also hadn't heard about. Apparently, she's an American student in Italy who has been convicted for murdering her British roommate. The reason she's a trending topic now is that her trial has just been resumed. Honestly, I think that having things like this in the news is somewhat useless, because there are much better things that the courts and the government, and even the people watching the news could be doing.
Third place was Erykah Badu, a singer and actress who I've never heard of. The only reason I can think of that she would be on the trending topics would be because she's released a new album.
Next was probably the most interesting. It was about USPS going broke. They claim that by the end of their fiscal year, Sept. 30th, they could lose $10 billion, leaving them with only enough money to continue running for about a week. Although this is obviously a negative thing, USPS hopes to use it to get permission from Congress to change their delivery schedules, close even more post offices, and lay off hundreds more employees. Although I think it is horrible that this has to happen right now, when the economy isn't growing at all, I know that doing this will improve our government's situation slightly for now, and contribute to a recovery.
Next was Global Markets, which in itself is so vague that I have no idea what to write about it.
Sixth was Eddie Murphy, who apparently is the main candidate, and top choice of Oscars producer Brett Ratner, for the next Oscar's host. I've heard of him before, but I don't know much about him. From the pictures I saw, though, he looks pretty cool, and I'm looking forward to the Oscars.
Seventh was Labor Day, which is obviously today, giving the reason that it is one of these topics. Apparently online searches for terms about Labor Day are down this year, but it's still a big vacation time. I also find the entire purpose of Labor Day pretty cool: to honor the social and economic contributions of our country's worker, and I believe it's especially meaningful at this point in time.
Eighth was Supernova. A supernova is one of the fates for a large star, and is the word for a large explosion by the star that spreads its outer layers rather than slowly creating a planetary nebula to become a White Dwarf. Apparently it is now visible to so called "backyard viewers", or anybody without a telescope. Last night, after our party, my dad and I spent a bit of time outside stargazing. We saw a reddish stripe that we believe might be this. It wasn't displayed on Google Star Maps.
Ninth was 183 wings, which made absolutely no sense until I looked it up. Apparently, at the National Buffalo Wings Festival in Buffalo, New York, Sonya Thomas, also known as the "Black Widow" set a record by eating 183 buffalo wings in just twelve minutes. That is just crazy. I don't completely understand the point of eating contests, but when a 5'5", 105 lb. woman eats that much food in such a short amount of time, I'm truly impressed.
The final topic was Hellen Mirren. I think I've heard her name before, but I didn't (and still don't) really know her. Apparently she is now acting in the movie, "The Debt" as a retired Israeli Spy who is now a Nazi Hunter. It sounds like an interesting movie and role.
Overall, the topics for today were pretty interesting. I had fun writing about them. I probably won't be able to write for a while, since I'll be busy with SIFP (take a look at my website at moneysenseseattle.webs.com), and school. Anyway, have a great September, and may the force be with all of you.

Here are some starter facts:
Factoids: Bioremediation is in general the use of microorganisms, fungi, green plants, and enzymes to restore an area to its original state. Source: http://en.wikipedia.org/wiki/Bioremediation Bioremediation has been used to clean up the following radioactive materials: cesium, chromium, lead, mercury, plutonium, uranium, strontium, and technetium. Source: http://www.woodrow.org/teachers/help/temp_presentations/kim/bioremediation.htm You can either use in situ or ex situ bioremediation. In situ involves treating the material at the site where it is found, and ex situ involves removing it and treating it somewhere else. Source: http://www.bionewsonline.com/w/what_is_bioremediation.htm Example: In Florida, the ECCO Commercial All-Purpose Cleaner has been used for the bioremediation of areas that have been affected by gasoline pollution. They are attracted to the small molecules of gasoline, making them easier to clean up.

I wrote this with my friends to review for our English final exam.
After getting shot in the heart, it didn't take long for his livelihood to abate. The doctors at the hospital bolstered his confidence of surviving. This was partially because of their confidence, but also partly because they had been coerced into it by the government. The government hoped to hearten this man because he was on the brink of discovering the secret to world peace. The man's life was fading so the doctors decided to augment his body with robotic parts. They thought he would be an exemplar of what humans should be like. But when they released him, he started shooting the city, and it turned into a bedlam. then the police brought in an aesthetic missile and assailed him with it. The man/robot became defunct. Then a volunteer police officer named Dwight went to clean up the fiasco. But as Dwight started cleaning, he started to feel magical and idyllic. He went to his beet farm, armed himself with awesome beet armor, and set out to assail his arch-enemy, Jeffry. But Dwight realised Jeffry had already met his demise, through suicide, and then Dwight realised he was his long lost sister Josaphine, and Dwight commited suicide. His parents were utterly brazen about his demise. His cronies were thrilled, but they didn't tell anyone. Shh... They threw the body down the gradient, and into the hiatus. It has been estranged ever since. As it came down, it hit a priest during his ablution, and knocked him out. Little did anyone know that this was the despot of an evil kingdo. So, although he had killed so many people, the man with the robot arms lived a happy afterlife because he did something good for the world.

Hello readers. It's been a while, and I've been pretty busy, but I'm back with a new thing that you can take a look at. I used this table while I was reading the book Macbeth to identify what some of the interesting words meant. You can use it yourself for the same purpose, or you can try learning some of this, and impress (as well as seriously confuse) your friends. I would like to warn you, however, that Elizabethan society itself was extremely different from our society today, so many of the these words would have different connotations that it seems. Enjoy!

Hello readers. With today being the end of the school year for me, and with most students year-end being just around the corner, I am going to post a series of entries about interesting work I did this year. I will also be creating an art page where I will be posting pictures of some of the art I've done in the past, as well as current projects. Enjoy!
