To The Student


In this post, cause I believe that limiting the curiosity (or at least waiting for the right time) is important, I want to share a good message to the students from Mary Boas.

To The Student

As you start each topic in this book, you will no doubt wonder and ask “Just why should I study this subject and what use does it have in applications?” There is a story about a young mathematics instructor who asked an older professor “What do you say when students ask about the practical applications of some mathematical topic?” The experienced professor said “I tell them!” This text tries to follow that advice. However, you must on your part be reasonable in your request. It is not possible in one book or course to cover both the mathematical methods and very many detailed applications of them.  (more…)

Lucy (2014)


Lucy is the new science-fiction film directed by Luc Besson. After my friends’ suggestion I’ve decided to watch it today, and after I started to watch the movie I figured out that the main subject of the film was the ‘Ten percent of brain myth’. As you can guess, the film is trying to answer the question ‘What it would be like if we use 100% percent of our brain’. I’m sure nowadays a lot of people believe this myth. Of course I’m aware that it’s a science-fiction movie, but how do we control everything around us if we use 100% of our brains. Or why do we need to control? I think that’s the thing that makes the film “bad” on from own viewpoint. Evolution is a natural process so it needs a lot of time to produce something. Ok, it’s a fiction, drug accelerated the process and gave the superpower to Lucy as a result she obtained ‘telepathy’ and ‘psychokinesis’ abilites. She reached the stars, made her own computer and so on. All these don’t seem different. These things have always been interesting for humans and that’s why the movie can’t answer the question properly. Indeed, it’s not easy to answer to that question. I don’t have an idea what if it would be like (if it was true). But I’m sure it will be not like as in the movie. Or, as a conclusion I can say we can’t make a prediction what it would be like if we use 100% of our brain while we are already using 100% of it.

Comparing new Oldboy movie with the old one


I’m not sure how much films I’ve watched but I believe that there’s too much. Of course there’s a lot of good films but when it comes to best ‘scenario’ Oldboy always has been special for me. Holywood version of Oldboy came to theaters on 2013 but I’ve decided to watch it today. I’m not being able to compare films with details, but I have to say that new one is worst. And I suggest you to watch the old one if you didn’t see the movie, if you did then you can try to watch the Holywood version –before doing that check the reviews on the IMDB page– .

One quote from Quora :

Actually I haven’t seen the Hollywood version of the movie, and never will! The angry reviews on imdb is enough proof for me that this is a movie that should never been made! The original South Korean movie is such a masterpiece that even thinking about a remake is silly. People should see the original one, end of story.

Compare the fight scenes in this video, what makes the old one better?  

 

 

Career Aptitude Test


I was reading the blog post on Lifehacker about finding the career path and I found this test. From Lifehacker;

Most of us have a variety of skills and interests, which makes choosing a career path tricky. Rasmussen College’s free online career aptitude test lets you rank your skills or interests and then suggests matching careers.

It’s less of a “test,” really, than it is a simple tool. Adjust the sliders and the results will rank occupations based on your particular mix. The downside is that your skills are self-reported, rather than tested through actual aptitude tests as some other career assessments tests do. However, it takes into consideration not just your skills but also interests, and suggestions are based on data from the U.S. Bureau of Labor Statistics.

I’v adjusted the sliders based on my skills, interests and the result is look like :

How are well-known physicists/astronomers viewed by the physics community?


Today, I have seen such an interesting question on Reddit. Here it’s the some well-known (popular) science writers.

  • Carl Sagan
  • Richard Feynman
  • Stephen Hawking
  • Brian Greene
  • Michio Kaku
  • Neil deGrasse Tyson

There’s to much answers to the question. The most rated is below.

Neil deGrasse Tyson / Carl Sagan

Very good popularizers of science. Did reasonable research back in the day (e.g., the level of an average prof at a good research university); but aren’t famous for their own research — is famous for their ability to bring science to the masses in an appealing way. EDIT: I’m not a planetary astronomer. Looking back Sagan did have a lot of very important contributions to planetary astronomy. Not Feynman/Bethe/Wheeler level but very good. NdT seemed to do very good work to get his PhD, but then seemed to move to focus primarily on popularization of science.

Stephen Hawking

Overrated because of his disease. Had a prof in grad school who was another big wig in black hole/gr research in the 1970s and Hawking gets nearly all the credit for it. But of everyone listed (except Feynman) is the only one who is famous for his own research. E.g., he’s easily one of the best 20 GR physicists of our time. But people often think of him as the next Einstein, Newton, Pauli, Fermi, etc when he’s really not.

Brian Greene

Friends at Columbia claim he’s quite annoying about his veganism. (E.g., will be upset if there’s any meat served at a department event). Personally, when I was in undergrad thought elegant universe was well done. Much better than Hawking’s BHoT.

Lisa Gerrard


Hep şunu söyleriz. Müzik göreceli bir kavramdır, bu yüzden kimse kimsenin dinlediğini beğenmek zorunda değildir. Ama ben bu konuda biraz kötümserim. Bana göre bazı müzikler ve sanatçılar var ki, asıl mesele görece olmak değil kendimizi ona yeterince konsantre edemediğizdir. İşte Lisa Gerrard’ta onlardan biri. (yoksa bana göre demem mi gerekirdi?) Şimdi bu kavramları unutup kendinizi ona vermenizi istiyorum.
