Ameri?ki shuttleovi napravili su do sada 114 letova u svemir, uklju?ujući i nedavni let shuttlea Discovery.

Temperatura na Zemlji kreće se od -88° do 58° C.
- najniža temperatura zabilježena je na Antarktiku (stanica Vostok, 1983.)
- najviša temperatura zabilježena je u Libiji, 1922
Volimo se brinuti o ženama, volimo ih tretirati sjajno, ali trenutno nemamo novca pa ih tretiramo kao smeće.

Dok se pomrа?enje Sunca vidi samo na ograni?enom podru?ju na Zemlji, pomra?enje Mjeseca vidi se svugdje gdje je Mjesec iznad horizonta.

Plejade su stare oko 100 milijuna godina. Kao jato, Plejade će postojati još samo oko 250 milijuna godina; poslije tog razdoblja, raširit će se kao pojedina?ne zvijezde ili višestruki zvjezdani sustavi.

@Shotif >> nema problema.

'Bones': Don't pander to me, kid. Solar flare might crop up, cook us in our seats. And wait till you're sitting pretty with a case of Andorian shingles, see if you're so relaxed when your eyeballs are bleeding. Space is disease and danger wrapped in darkness and silence.
Kirk: Well, I hate to break this to you, but Starfleet operates in space.
'Bones': Yeah. Well, I got nowhere else to go, the ex-wife took the whole damn planet in the divorce. All I got left is my bones.

Kisik je prona?en tek 1874. Nije utvr?eno kako su ljudi disali prije toga :D

oko naše galaksije nalazi se zvijezdani prsten promjera oko 120 tisuća sv.godina. pretpostavlja se da je nastao kad se naša galaksija sudarila s nekom manjom galaksijom prije otprilike 10 milijardo god.

Mooreov zakon


opažanje Gordona E. Moorea (suosniva?a kompanije Intel, 1968.) u 1965. godini da svaki novi krug s integriranom memorijom sadržava dvostruko više kapaciteta od svog prethodnika i da se novi ?ipovi pojavljuju u razmacima od 18-24 mjeseci. Ovo zna?i da se kompjutorska snaga mijenja eksponencijalno s vremenom. Gustoća ?ipa po jedinici površine u tranzistorima udvostru?uje se približno svake 3.3 godine. Kako karakteristi?ne dimenzije na novim ?ipovima postaju sve manje, predvi?a se da će nove generacije ?ipova morati biti strukturirane na skalama nanometara. Do 2012. godine, karakteristi?na linearna dimenzija uzorka na ?ipu (ži?ica, tranzistor...) morala bi biti na skalama od 50 nanometara ako o?ekujemo da Mooreov zakon vrijedi i za budućnost.

Bilo bi poželjno neke tamne nao?ale staviti prije gledanja u to...

I hold a scrap of paper in the darkness and light it. I watch it burn bright and curl, disappearing into nothingness, and the heat burns my fingers. Where has it gone? What has it become? I cannot shake the feeling that I have witnessed a form of transcendence.

Peter: Walter, what are you doing?
Walter: I'm dosing a caterpillar.
Peter: Dosing? As in LSD?
Walter: It's a special blend.
Peter: I see. Hey, guess what just happened? Finding out that my father gives drugs to bugs, somehow just became a typical moment in my life.
Walter: Wonderful, isn't it?
