Hot water freezes faster than cold water.Seemingly impossible noh? But it happens. Kaya nga lang, sinabi samin sa Physics 73 na impossible yan (or on what I remember, quiz ata yun). It happens and it was discovered (wrong term) by some Tanzanian kid experimentally. Galing. It puzzled several scientists at maraming beses na napublish sa Physics journals. Ana proposed this for Physics 73.1 investigatory project kaso mababaw daw (ata, malabo na memory ko) sabi ng prof kaya nareject.
Wala lang. Kagulat-gulat.

You time-traveled back to the past and killed your grandfather even before your father was born. Then, can you kill your grandfather when you killed yourself too?
Almost 3 hours akong binagabag ng paradox na yan. At wala akong naisip na resolution.

Hindi ba no? Haha. :D
Well, di ba magagawa mo parin?
Imagine mo na masasaksak mo siya. Ang gulo!
Mpemba effect ang tawag diyan. Kung napaka-pure ng tubig na gagamitin, tama ang Physics 73 teacher mo. Puwedeng lumabas yung effect pag may impurities. Ang isang hypothesis ay ganito pag may solutes sa tubig na gaseous puwedeng magkaroon ng freezing point depression. Itong mga solutes na ito nawawala kapag ininit mo yung tubig dahil mas soluble na sila ... Mahabang kuwenot, punta ka na lang dito: http://www.arxiv.org/abs/physics/0604224 at dito: http://www.arxiv.org/abs/physics/0512262
Wow! Salamat anonymous ha. Nakita ko nga entry nito sa Wikipedia pero malabo ang theory behind.
"Itong mga solutes na ito nawawala kapag ininit mo yung tubig dahil mas soluble na sila"
--> Contradictory eh?
