Life in Pi

I’ve recently read how Pi (as its digits are infinite, being an irrational number) could contain any number that you can think of, that is, every and any possible finite sequence (for example my birthday is found at position 12’474’857; find yours: here). Obviously, the date of birth is rather a short string, but if you think that any finite sequence could occur somewhere in Pi, this means that not only your birth date is …

Timeline of scientific discoveries

Here you can find a list of the major scientific discoveries made since the 2nd century BC. If you ask someone which would be the greatest discovery ever made, you might get all sorts of answers ranging from electricity to the Higgs Boson, the Human genome, theory of relativity and so on. The fact is that when I come to think of it, the biggest life-changing discovery I’s say would be the Internet (although Internet …

timp imaginar

In urma publicarii pe fb a unei mici glumite, pe care o redau — pentru amuzament — mai jos, dar si urmare a unei mici discutii privind existenta numerelor imaginare, mi-am adus aminte de un concept despre care am citit prima data intr-o carte a lui Stephen Hawking intitulata A brief history of time. Este vorba de timpul imaginar. Dar mai intai glumita: “i” arguing with “pi” i: be rational! pi: get real.. rad efectiv …

GooglePleaseHire.me

Ever wondered what happened to Matthew Epstein’s quest of getting a job at Google? (http://googlepleasehire.me/) Well, in his own words: “No, Google didn’t hire me nor did they extend an offer to me. That’s right ladies and gentleman – the big G turned me down. Why you ask? I’ve thought a lot about it and in all honesty I don’t know why. Unfortunately Google didn’t tell me why I didn’t receive the job but in …

Symmetry kills curiosity

This posting is actually a memento, for me, in order to remember later on this expression i coined when i was trying to explain my webdesigners that not everything needs to be perfectly aligned with everything else or to perfectly fit into a perfect symmetric way and so on. For the eye, what it is where it should be, is most probably a blind spot. This may sound counterintuitive but it’s not. Think at Seth …

Cum a ajuns Einstein la E=MC2?» 

Raspunsul scurt: din intamplare (insa tot geniu ramane). Raspunsul nu atat de scurt (dar nici complicat, matematica de liceu fiind indeajuns): Einstein a pornit de la principiul relativitatii enuntat de Galileo cum ca legile fizicii sunt aceleasi intr-un sistem aflat in repaus cat si daca acesta este in miscare constanta (sistem inertial, fara acceleratie) si l-a extins afirmand ca legile fizicii sunt aceleasi in orice sistem inertial, oricare ar fi acesta. Principiul lui Galileo este …
