RF Shorts: FLO-TV and Arrow of Time Paradox

  • • With the growing interest in mobile television, it isn't surprising that rumors have surfaced about Qualcomm developing a hand-held TV about the size of an iPhone. The device would allow consumers to view its FLO TV service without going through wireless providers or purchasing the subscription as part of a mobile phone plan. Will the new "'mobile FLO" include the ability to receive ATSC mobile DTV transmissions? That might make it more interesting to consumers. Stories about the rumor are available on several web sites. Crunchgear.com describes it in the article Rumor: Qualcomm FLO TV is coming.
  • • The Web site Physorg.com has an interesting article on the Arrow-of-Time Paradox. This paradox refers the apparent conflict between the laws of physics, which are time-invariant (laws hold true even if time is reversed) and the second law of thermodynamics, which says that entropy always increases or stays the same, but never decreases. Theoretical physicist Lorenzo Maccone, currently a visiting scientist at MIT, offers a solution to this reversibility paradox (also called Loschmidt's paradox) based on quantum mechanics. The short explanation is that entropy can decrease for certain phenomena but these phenomena won't leave any evidence of their happening.
