Guess who's back!

After a three days at Bran, where I slept something like 12 hours a day, I'm back online. The break at Bran came after what I currently consider to be the most important event in my life: the International Physics Olympiad. Not only have I been the farthest away from home (almost 9000 km) and visited Singapore, but I have also obtained quite an important award: Silver Medal at IPhO. Let's take them one at the time.

I shall begin with the coutry of Singapore. At the first sight, it seems like an utopia. Everything over there seems (am probably is) brand new: all the buildings, outdoor and indoor, look like taken from an US movie that depicts a luxury neighborhood of, let's say, New York. The catch is that New York also has poor neighborhoods; in Singapore, as far as I have seen, there aren't any. Everything is clean. Nobody throws anything on the street. Smoking students are a minority. You are not expected to tip the cab driver, and he gives you the change to the last cent. Oh, and the 90Km/h speed-limit on the high-way is respected by almost everybody (the cab drivers make the exception Image ). Needless to say the people love their country in a manner Ceausescu could only dream of. This is only my first impression, but it's a strong one. It might change only if I live in Singapore, and I don't see that happening too soon.

Now about the Olympiad. It was nice. I found two of the three problems easy. The last one... well... had I only known relativity Image. I crawled my way trough it, but feeling extremely unsecure in the subject, I just failed to do it right. They however gave me 4.5 points for it. Nice. As for the experimental paper, I think I speak in the name of the whole team when I say "We blew it!". Unacceptable mistakes at very simple things. All of us. Weird, huh? Now, I guess other students blew it at the theoretical paper, where Romania had some strong scores. The conclusion: one Gold, two Silver and two Bronze. We can not compare to countries like China, Taiwan or South Korea (with 4 or 5 Gold), but it is nevertheless a good result. May it be better next year!

Why is this in English? Well, I will be going to Britain this year and my blog must reflect it. Plus I want the people I met in Singapore be able to read it (Hi Cheryl!)

"Pe curand!"

P.S. I almost forgot. Singapore is heaven for those who like science and engineering. It's two technical university (NTU and NUS) conduct lots of research programs. H.E.A.V.E.N. Take my word for it!

Not home

Cam pana pe 21 iulie 2006 nu voi fi acasa, si nici nu cred ca voi mai intra pe net. Asa ca, see you when I'll see you Image !

Reinstalare de Windows...

Mi-am amintit diferentele esentiale dintre Windows si Linux: Windows arata mai frumos si se blocheaza mai des. L-am instalat pe curat, cu formatare. Am downloadat driverul video de pe site-ul ATI. L-am instalat. Restart. Restart. Restart... Something's wrong Image. Last known good configuration. Acu stau sa downloadez driverul de pe site-ul ASUS. Degeaba am ATI Radeon, daca placa e ASUS. Are 100MB, si downloadul merge cu 10KB/s. Pe cat mi-a luat pe Linux instalarea driverului (si macar acolo simti ca-l instalezi TU), pe atat imi ia acum downloadul lui - nu s-au obosit sa faca mirror-uri rapide. Si o sugestie, folositi FlashGet. Nu am gasit alt download manager free care sa foloseasca in paralel mai multe mirror-uri.

Intre timp ma dor ochii de la cei 60Hz. Merg sa mai citesc ceva la fizica...

Later edit. Nici driverele ASUS nu merg, nici driverele alternative Omega. Acum incerc un downgrade. Inca mai exista speranta.

Final note. A mers. Driverele 6.5 si 6.6 de la ATI nu-mi merg, dar cu 6.4 e okey.

Probleme adevarate...

... se gasesc in culegerile straine. Sau traduse dupa culegeri straine. Va dau un exemplu de problema, absolut superba. Te unge pe suflet Image . E exact genul de problema care parca iti spune s-o rezolvi (suna tare, nu? asa ma gandeam si eu...)

A chain of mass M and length L is suspended vertically with it's lower end touching a scale (sa zicem un cantar). The chain is released and falls onto the scale. What is the reading of the scale when a length x of the chain has fallen? Neglect the size of the individual links.

Aceasta e prima problema dintr-o minunata carte A Guide To Physics Problems. Cei interesati o pot gasi pe . De prea mult timp nu am mai fost asa entuziasmat de o carte... cu probleme de fizica!


P.S. Concurs: Care o rezolva primul?

P.P.S. Cei din lotul mic nu au voie sa participe Image
