  • Singularity Signposts – 11may2009 ‘Physical Intelligence’

    George Rebane Physical Intelligence (PI) is the latest AI paradigm added to the efforts to develop machines smarter than humans.  A few days ago DARPA (Defense Projects Research Agency), the people who brought you the Internet and other spooky things you shouldn’t know about, posted a notice announcing informational workshops as a preamble to issuing RFPs…

  • Cognitive Radio??!!??!!

    George Rebane With the recent explosion of mobile intelligent devices, cell phones, PDAs, laptops, netbooks, etc, etc, all speaking wirelessly to each other through various networks (clouds), the airwaves have become very crowded.  The electromagnetic (EM) spectrum is pretty much fixed by the design of our universe, so it looked like we were going to…

  • Ruminations – 11mar2009

    George Rebane Ending ‘Market-Based Government’ is a banner for Obama’s reform of government procurements from the private sector – especially in the defense sector.  The media elevated ‘outrages’ by service contractors like KBR and Blackstone in Iraq during the Bush years made a big impact on an electorate historically constrained.  Nobody remembers or has read…

  • ‘Ethanol Faces Facts’

    [A correspondent sent me the following article on carbon footprinting of ethanol production by D.T. Adolphus that was initially published on the Hemmings eWeekly newsletter.  With minor format editing for readability, I have decided to post the entire article.  It sheds needed light on the important facets of the ethanol issue, and in the process shows…

  • Ruminations – 16jan2009

    George Rebane We may be living in a hologram, in fact the entire universe may be a hologram.  The GEO600 project in Germany is geared to detect noise in the gravity wave background (think of the cosmic microwave background noise that points to the Big Bang) that would up the granularity of spacetime by about 20…

  • Ruminations – 21dec2008

    George Rebane Happy Winter Solstice to everyone.  At 4:04 AM PST this morning the sun was exactly overhead somewhere at the Tropic of Capricorn latitude in the southern hemisphere.  For Jews everywhere Hanukkah, the festival of the lights, starts this evening at sunset.  Christians have today lit the fourth candle of Advent and await the…

  • BS Levels High – Sea Levels Uncertain

    George Rebane Reading a recent post on NC Media Watch on climate change and sea levels made me go back and redo some previous research on the difficult problem of measuring sea levels.  The bottom line is that measuring the earth’s sea levels (yes, there are many of them) is still a difficult and unsolved…

  • Multiverses All the Way Down

    George Rebane The existence of an Intelligent Creator (IC), aka God, is so abhorrent to some scientists that they are willing to jump through any number of hoops to avoid satisfying at least one of the pillars – Occam’s razor – on which science claims to rest (the other is Falsifiability).  Instead they are advancing…

  • Political Phollies Phuse with Physics

    George Rebane   Worldwide lunacy is achieving new heights.  The Europeans are launching a major multi-decade project to create a practical energy source using fusion.  This project will cost megatons of money – some will undoubtedly even come from the US – and seek to create energy independence from carbon based fuels.  The story is…

  • Bouncing Toward ‘Why?’

    George Rebane The ancient Vedic philosophers taught that the universe was cyclic and very old.  Its age is measured in kalpas for which the Vedantic derivatives of Hinduism and Buddhism have a variety of spectacular definitions.  From my late teen years, my own favorite is the length of time it takes a granite cube, 25…
