Lost in Translation

I just fixed my DVD player, which has touble with remote control for about one year.

It turns out that the remote is fine, while the receiver inside the player causes all the trouble.

After opening the box, removing all the srews I can find, the receiver eventually shows up: two legs of its triode are stuck together, which short circuit the element, and stop it responding any signal.

I can imagine what happened: some worker oversea(probably someone in my hometown) try to assemble the unit by brutal force, crush one leg onto another. This also explains the situation before: pushing ”picture” button(which turns out to be the nearest one to the triode) on the panel several times may solve the problem temporarily.

Philips must do better than this to maintain the product quality.

Anyhow, I just proved I am a physicist.

Ambassador Edward Peck

Criticism of G. W. Bush plan to invade Iraq and of Middle East policy

Edward Peck argued against invading Iraq prior to the March 2003 invasion. He argued, in part, “when you take out Saddam Hussein, the key question you have to ask then is, what happens after that? And we don’t have a clue. Nobody knows, but it’s probably going to be bad. And a lot of people are going to be very upset about that, because that really is not written into our role in this world is to decide who rules Iraq.” Peck has been highly critical of U.S. policy toward Israel, arguing through the Council for the National Interest (CNI) in which he plays an active role, that the U.S. should be more even handed in its Middle East policy. He argues that while Hezbollah could be considered a terrorist organization, it is no more terrorist than Israel or the U.S. itself. He supports a dialogue with Hezbollah. He claims that in 2000, at the Camp David talks, Israel offered the Palestinians “12 little Bantustans [see December 22 interview link below].” His speech was publicized in a documentary produced by If Americans Knew.

Speaking in July 2006 to syndicated US radio news programme Democracy Now!, Peck said that:

“In 1985, when I was the Deputy Director of the Reagan White House Task Force on Terrorism, they asked us — this is a Cabinet Task Force on Terrorism; I was the Deputy Director of the working group — they asked us to come up with a definition of terrorism that could be used throughout the government. We produced about six, and each and every case, they were rejected, because careful reading would indicate that our own country had been involved in some of those activities. […] After the task force concluded its work, Congress got into it, and you can google into U.S. Code Title 18, Section 2331^[1], and read the U.S. definition of terrorism. And one of them in here says — one of the terms, “international terrorism,” means “activities that,” I quote, “appear to be intended to affect the conduct of a government by mass destruction, assassination or kidnapping.” […] Yes, well, certainly, you can think of a number of countries that have been involved in such activities. Ours is one of them. Israel is another. And so, the terrorist, of course, is in the eye of the beholder.”^[2]

Jeremiah Wright 

In September 2001, Reverend Jeremy Wright in a sermon quoted ^[3] Peck as allegedly having said on a Fox News broadcast: “We bombed Hiroshima, we bombed Nagasaki, and we nuked far more than the thousands in New York and the Pentagon, and we never batted an eye…and now we are indignant, because the stuff we have done overseas is now brought back into our own front yards. America’s chickens are coming home to roost.” ^[3] In March 2008, during the presidential campaign of Barack Obama, spliced excerpts of these quoted statements from the sermon were broadcast on ABC News, and attributed to Wright. ^[4]

我对中共的愚蠢和自大表示深切关注

西藏事件发生后，西方部分媒体歪曲报道，而旅外学子和有志之士发现后怒发冲冠，将种种证据和真相列于网上，Youtube成为我们抵抗无良媒体的有力武器。

而此时此刻，你们在做什么呢？

Akin Wingerter’s talk today is about building MSSM-like model from string compactification.

Gauge hierarchy and family structure of fermions confused a whole generation of people. We are so eager to have a more fundanmental(or upper) understanding that we counldn’t help building all possible toy model based on imagenation. People like this can get jobs simply because, a real “top-down” touch is just impossible. Roughly speaking, everything can happen.

Akin Wingerter and cooperation tried a hybrid way: they guess a semi-completion from low energy Standard Model(SM), then scan all possible true UV completion a.k.a. string theory, based on rules obtain from SM requirement.

The GUT scale model they considered is a 6-d with 4-d flat while other 2 compactified into torus adding Z2 symmetry(so called orbitfold). The gauge field is SO(10) inside bulk and SU(5), SU(4)XSU(2)XSU(2) etc on the fixed point. The real world people living in 4-d observe an intersection which is SU(3)XSU(2)XU(1) SM gauge.

A good news is the solutions are usually rare. For instance, in heterotic string case, using a generic form superpotential, they found number of solutions as 15.

The first bad news is a technical one, you may run into wrong Yukawa matrices. It may not be a real problem, for higher order operators can be added. Except for that, fermion mass hierarchy can be explained by string instanton, location in extra dimension or whatever your favorite in string theory, while VEV of moduli over compactification scale buy you more suppression factor.

A real bad news is proton decay. The reason is simple: no one so far know how to build a non-susy domain wall, thus they require a GUT susy. The consequence is the exsitance of power 5 operator which cause proton decay fastly. Another problem is SUSY breaking now may lack messenger sector.

I think this work is pretty good. We don’t know whether the true world is reduced from a heterotic string or a type-II one. We don’t know whether there exists non-susy orbitfold either. The only way to get an answer is to try hard. Their work shed a light on how to try. And string theorist will be happy, for their work could be linked to our real life, maybe not now, maybe in a complicated way. 

This is a talk given by Jon right before Thanksgiving. 

he and Adam Falk’s work is about one soft breaking term that people previously thought may appear in supersymmetry breaking lagrangian. They study from spontonously breaking way, found goldstino loop always appear along with this soft breaking term, just as pion decay term always appear with mass term(Goldberger-Treiman relation). Thus, if you don’t suppress the breaking term by suitable power counting factor(after that it will become small), the goldstino loop will destablize your vacuum.

Cool job.

I was shocked today when a friend told me there are lots of comments on this blog which I have not visited for several months.

It seems too many people have been scamed by some magazine sellers on ebay(probabally not the same one). You may have the same experience as me: got scamed, waited for too long, negociated with paypal or ebay or credit card company, got at most half of your money back if you can stand for the never-ended negotiation.

Someone left a comment describing how those guy buy feedback on ebay. I am too dumb to understand the detail, and I never thought thing could be so complicated. Thus, I simply decide to keep myself far away from any ebay magazine seller.

This letter is about payment ID # 3PC97182T7702022Y, made in May 25. For I was cheated by seller and can not get paypal protection!

Seller, “magazinexpress”, real name Lori O’Reilly was selling magazine at cheap price, persuading everyone can get magazine in 8 to 12 weeks. It was a scam, I have not got anything, and she becomes a “unregistered member” on ebay now.

I try to file a complaint, but paypal said it is too later. I tried to call, but it leads to your autovoice system.

When I paid 40 bucks, I am confident because I trusted ebay and paypal. But now, I am wondering days and nights how things like this can happend. When someone stole my money, I feel terible, when you denied my request for help, I feel disappointed and hopeless.

I think you should do more to protect buyer thus I write this letter for help and refund. I am also willing to help to pin this guy down.

Dear ebay:

We all know once you fall in a trap you must act quickly, that is why both ebay and paypal allow 45 or 60 days for buyer to open case about possible scam. However, there are sellers playing around this rules. I met one.

I bought item 270123452341 two months ago. This seller, namely “magazinexpress” was selling magazine at cheap price, persuading everyone they could get magazine in 8 to 12 weeks.

I never got it. As the seller said, I have not waited for enough time. Should I REALLY listen to him or her and wait? Of course not. Because this “magazineexpress” is not a registered memeber in ebay any more!! Please check this link if you want:
http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=270123452341&sspagename=ADME:B:AAQ:US:1

The email he or she provide is a fake one. You can never send anything to magazinexpress@twcny.rr.com

I wondered days and nights how things like this can happen. The problem is, timing. He ask anyone to wait at least 12 weeks, which secretly passes ebay’s 8 weeks window to file any complaint. Then he or she just need to clean up every item and wait for 45 days to close both ebay and paypal account then go.

I admit I am too stupid to find this, and even now I can not figure out where 95% positive review this seller got from. Maybe he or she also send out lowest price order. Maybe the whole thing is just a big hoax.

Right now I find another seller, “magazinesrusa” who is selling the similar stuffs, if you want, please check this item: 280140532263. I highly suspect “magazinesrusa” and the former “magazinexpress” are related.

In order to pretect more custom from similar scam. Do you know to whom I should report? You answer will be highly appreciated.

Today, Gritsan mentioned how to calculate distance defletion inside detector — chop it into slabs.

This idea is exactly as the way Lorentz got the formula connecting reflection index and scattering amplitude, which further helped Krammers and Kronig got optical theorem.
Optical Theorem connects two things, total cross section, and forward scattering amplitude. Rediculous at the first sight, it is incredible as you give a second thought. Let us have a close view at what happened between Lorentz and K&K. The earlier person got a macroscopic quantity, reflection index, as an expression of a microscopic quantity, scattering amplitude. The story is pretty similar to atomic hyperthesis and classic theromal dynamics. Just because nature is it, no deeper reason. However, K&K reconsider a more macroscopic quantity, intensity from a more macroscopic varible, total cross section. The formula become so straightforward that once you wrote it down, everything just show up in the exact place you want. Then, they require these two to be the same, bam! optical theorm.

A second way to do it is drawing Feymann diagram, you will soon notice you are doing something stupid —- you forgot the simplest case! Write it down, read it, you got optical theorm. 

It is snowing, slightly, not hard.
I heard it is snowing, while sleeping in bed. Wind’s whisper through slits between windows, tick tick on the double glass, and pieces of evening news you still remember before the latest sweet dream, with your sweetheart of course, everything just tell you it is snowing, before you open your eyes.
Happy Valentine’s Day.

Our shool is closed due to bad traffic and slow progress on cleaning in campus. However, this news is sent out just when we arrived, after a long long walk in the drizzle and dirty shower from passing car.
To be more ironic, I find our professor in his office, who is the only person in this floor, you know what I am thinking about? The latest episode of Everybody Hates Chris! So let us start the class, lecturer and lisnter, let us call the roll. Before my dream comes true, he put up all the clothes, and left.

Snowman, Snowmen… Snowwomen

   

 

  

  

Happy snowy day.
