  • ‘More UN climate nonsense’ (updated 3aug25)

    George Rebane James Freeman in the 23jul25 WSJ writes a telling article on the intended confusion that surrounds ‘sustainable energy’ costs – i.e. the comparison of wind, solar, and hydro to fossil fuels.  The latest pile of steaming bullshit was regurgitated by UN Secretary General Antonio Guterres in an AP interview as reported here.  I…

  • Getting from here to there

    George Rebane OK boys and girls, it’s time to take a break from our socio-political harangues and debates, and delve into something more intellectual yet delightfully accessible.  The figure contains a 10-by-10 network of nodes each identified by their blue numbers from 1 to 100.  The related red numbers denote the cost of traversing that…

  • Growth and ONLY growth

    George Rebane The Republican debate about the Big Beautiful Bill (BBB) goes on after it squeaked out of the Senate with the VP’s vote.  A quick look at the alternatives shows that the debate involves no reasonable alternative to the BBB.  Everyone except the economically ignorant leftwingers in the country knows that the only solution…

  • What is ‘fair’? – one more time

    George Rebane The use of ‘fair’, as in ‘the rich need to pay their fair share’, is one the most nefarious misuse of language in the public square.  Oxford Languages defines the adjective as “impartial and just, without favoritism or discrimination”.  Arrow’s Impossibility Theorem (Nobel 1972, here) proves that in collective decision making among alternatives it is…

  • Our Chinese Communist benefactors

    George Rebane [This post appears in the 9jul25 edition of The Union’s op-ed pages, retitled with the atrocious and confusing word salad ‘US political factions push socialism to achieve Chinese Communist Party levels of control?’ (Note the question mark.)  The newspaper also refused to include the accompanying figure which makes clear to the layman an…

  • B-2s over Iran (partially restored)

    George Rebane [This 23jun25 blog post was mysteriously deleted by Typepad which they cannot recover.  I fished out a partial draft version of the post from the Recycle Bin and am reposting it here.  It does not include the two updates and graphics of the original of which I don’t have copies.] Don’t let an…

  • Scattershots – 10jun25 (updated 13jun25)

    George Rebane Fossil Fuel Use and Human Progress: The Big Picture More here (H/T to reader). The Left’s riot lies are now historically astounding (more here).  And what makes this both sad and dangerous is that your Democrat neighbor completely believes what s/he hears from Maxine Waters, Hakeem Jeffries, Chuck Schumer, and the other leading…

  • Triangle Problem

    George Rebane Two circles of areas A1 and A2 are embedded in an equilateral triangle as shown below.  What is the area of the triangle? ©2025 GJ Rebane  

  • Those discriminating selfish countries

    George Rebane The Marschak Colloquium is a 50+ year institution at UCLA that features world class thinkers, artists, and scientists as invited speakers.  Jo Ann and I were in regular attendance when we lived in SoCal.  As with academe in general, Marschak has drifted leftward ideologically.  The next scheduled talk will be given by a…

  • A little puzzlement (updated 23apr25)

    George Rebane As a fun diversion, here’s your Easter Egg problem albeit with a round egg.  Given three mutually perpendicular line segments of lengths a, b, c, as shown in the figure,  Problem: (A) derive the expression for the radius r of the circle, then (B) for (a, b, c) = (13,6,18) calculate the value…
