It is dangerous out there, didn’t you know ? Asteroids all over the place. And, again, some news about how Jupiter helps us (or not):
An interesting point about the orbits is how so many of them are tucked inside the orbit of Jupiter, with only a few shooting beyond to the outer Solar System. That makes Jupiter a bit of a two-faced friend. On the one hand, having a giant planet in the neighborhood is great because in the early days of the Solar System it swept up all the cosmic debris (...)

Vibrations in the real world
2 July 2013, by Valentin MurariuOf course, you don’t believe in all the new age stuff with vibrations and all, don’t you ?
So, let’s introduce you to the visible part of it: Exhibit #1: water and sound experiment:
https://www.youtube.com/watch?v=uENITui5_jU
What is nice, is that you can build it yourself (almost easily):
– a speaker
– a water hose connected to a water supply
– tone generating equipment
– a 24 frames-per-second camera Exhibit #2: the resonance experiment
This one starts with a quote from (...) -
Mighty alcohol
2 July 2013, by Valentin MurariuSo, my friends, as human knowledge gets more diversified, the guys at Discovery News tell us that alcohol can be/is created into deep space, where the temperature comes close to absolute zero. How that can happen ? The smart guys tell us: Through a quirk of quantum physics, it’s possible for two particles to overcome the electrostatic barrier. The quantum “wave-like” nature of particles allows a small probability that “quantum tunneling” may occur through the electrostatic barrier, an (...)

Silence
15 April 2013, by Valentin MurariuI am reading Peter Høeg’s fiction "The Quiet Girl" (Den stille pige), 2006. The book is a thriller, and ... no, I am not going to you tell the story.
The point is that the book mentions every now and then the "silence": as I read it in French, and the quotes are from the book, here you have some pieces:
...J’ai cherché ce silence-là toute ma vie... Et si tu mettais de boules de Quiès ? Il y aurait encore du bruit. Le bruit du corps... mes propres pensées. Le silence que je cherche est (...) -

Ce meserie o să ai ?
30 iunie 2011, de Valentin MurariuÎn Elveţia se organizează in fiecare an "Journée des filles" - părinţii işi aduc fetele la lucru şi le arată cum işi caştigă painea zilnică. Ideea ar fi să le tenteze pe fete să nu işi limiteze opţiunile de carieră la meserii care sunt, in mod clasic, asignate fetelor.
Succesul unei astfel de iniţiative la serviciu la mine poate fi măsurat de următoarea remarcă, scrisă pe un whiteboard de către o fetiţă neidentificată (incă):
Salut toi, ça va ? Moi je
m’ennuie à mourir
parce que ma (...) -
Endianness
15 iunie 2011, de Valentin MurariuCurs de sisteme de mediere pentru telecom. O lunga discuţie are loc despre diverse formate binare de CDR - şi un mic război despre codări are loc: de ce little-endian sau big-endian ? După jumătate de oră de discuţii inflăcarate, citesc pe wikipedia despre etimologie şi mă amuz căci imi dau seama că termenul vine din "Călătoriile lui Gulliver" de Swift:
The term big-endian originally comes from Jonathan Swift’s satirical novel Gulliver’s Travels by way of Danny Cohen in 1980. In 1726, (...) -
Anatoli
21 May 2011, by Valentin MurariuEmoţie pură ! Recitalul Anatoli a fost un moment.
Citat de pe site-ul spectacolului: « Les chants des hommes sont plus beaux qu’eux-mêmes, plus lourds d’espoir, plus tristes, plus durables. Plus que les hommes j’ai aimé leurs chants. J’ai pu vivre sans les hommes, jamais sans les chants; Il m’est arrivé d’être infidèle à ma bien-aimée, jamais au chant que j’ai chanté pour elle; jamais non plus les chants ne m’ont trompé. Quel que soit leur langage, j’ai toujours compris tous les chants. (...)
