 October 18, 2021 Saturdays and Wednesdays are my hiking days with a small group of adventurers in the mountains, valleys, streams, and sometimes top of the mountains traverses. This Saturday we took some offshoot trails off of the main Ohana Trail on windward Oahu. The ascent was a good workout on an uncleared but very navitagable trial to our usual lunch spot at the crest of the main Ohana trail. Since I was the organizer of today's hike we went down Iron Maiden a mostly steep winding bike route off the mountain. Just as we started along the narrower but not steeper part it poured (Mauka shower) so the bike dirt packed narrow trail was now slick and muddy. We all had spikes on our boots but quickly they became ineffective so sliding and imbalance down the steeper switchbacks led some of us to just sit down and mud slide to more level areas. Slowly we descended with some of us squealing with delight and trepidation whenever we did our mudslide maneuver. I know one our group was ve

 October 7, 2021 I've been busy with my usual activities but recently concentrating on understanding quantum physics (the physics of the very very very tiny) by reading articles (esp.  Suskind wormhole theory of black hole https://en.wikipedia.org/wiki/ER_%3D_EPR ), Katie Mack's The End Of Everything (Astrophysically Speaking), Lee Smolin  and loop gravity theory in Einstein's Unfinished Revolution The Search for What Lies Beyond the Quantum, and finally Sabine Hossenfelder's Lost in Math book rant on theory making, math beauty, quantum theory, and the scientific communities problems in getting stuck in outdated unproven theories and the short changing of progress in new research and  new theories.  For example, in quantum mechanics once you measure something very very very small (i.e. position or momentum) you have by your measurement found one or the other measurements (decoherence) and influenced the particles characteristics to influence the other paired particle s
