 +10:28:27 From tedpk to Everyone:
 + Where do histamines fit into all this -- since this is the height of Seasonal Respiratory Allergies?
 +10:57:07 From Judy & Mike Alexander to Everyone:
 + The prediction quote is attributed to Yogi Berra, not Niels Bohr
 +11:18:38 From Bob Primak to Everyone:
 + The allergy discussion raises my own experience with a recently discovered severe allergy. I_t was very specific.
 +11:18:56 From Bob Primak to Everyone:
 + I am undergoing treatments for my severe sting allergy.
 +11:19:31 From Barry Kort to Everyone:
 + • It’s hard to unlearn a chronic negative reaction to an irritating stimulant.

 +10:07:16 From Bob Primak to Everyone:
 + For travel backward in time, has anyone solved the paradox of conservation of energy and mass?
 +10:12:12 From Bob Primak to Everyone:
 + As an absolute physical constant, the speed of light recently has been questioned. Over long times and distances, some theorists seem to think light may be slowing down.
 +10:19:43 From Bob Primak to Everyone:
 + Chicken and egg -- the first chicken did not come from a chicken egg -- it came from a dinosaur egg!
 +10:20:05 From Bob Primak to Everyone:
 + (Not chickens specifically, but birds, generally.
 +10:27:19 From Jerome Slate to Everyone:
 + To know which came first, the chicken or the egg, order both from Amazon.  You will soon know which came first.
 +10:31:30 From Stan Rose to Everyone:
 + Interesting that these are all ideas in the Netflix series, 3 Body Problem!
 +10:33:56 From Bob Primak to Everyone:
 + I ordered a chicken and an egg from Amazon. The chicken was at Whole Foods before I ordered it. (It was already in my cart.) What does this result prove?
 +10:39:32 From Dan Silber to Everyone:
 + I have long agreed with Bob - eggs came into existence before chickens.
 +10:43:24 From Adam Broun to Everyone:

 + All the courses in this series are terrific if you want to go  that deep
 +10:55:58 From Judy & Mike Alexander to Everyone:
 + Eggs must be fertilized before there are chickens.  "Chicken vs. egg" is incomplete.
 +10:57:02 From Bob Primak to Everyone:
 + We should be careful about eliminating the genes responsible for allergies. There are some scientists who think allergies are part of our very complex immune systems. Change one part of this system, and unpredictable effects can happen elsewhere in the immune system.
 +10:57:09 From Barry Kort to Everyone:
 + Brand new 37-minute video from Veritasium on black holes, white holes, wormholes and parallel universes, entitled, “Something Strange Happens When You Follow Einstein's Math” ~ https://youtu.be/6akmv1bsz1M
 +10:59:40 From Steve Isenberg to Everyone:
 + Veritasium has good presentations, we’ve seen some in the past.  I’ll put this on the Potentials list, maybe we can show it in a potpourri.
 +11:00:43 From Barry Kort to Everyone:
 + Derek Muller of Veritasium is a world-class science educator and explorer on YouTube.
 +11:01:28 From Bob Primak to Everyone:
 + "Designer Genes" could have ethical and population health consequences. Diversity has been one key to genetic evolution. This process is necessary when, not if the Earth's environment changes radically in the future. (No implication of human causality in these changes is needed to see this issue.)
 +11:05:14 From Bob Primak to Everyone:
 + Ack!! Did they just refer to human genetics as a "hard drive??

 +===About Eclipses===
 +<WRAP prewrap>
 +<code>
 +09:53:53 From Barry Kort to Everyone:
 + PBS NOVA will probably produce an episode on the topic.
 +10:02:55 From Bob Primak to Everyone:
 + That airs tonight on PBS-2.
 +10:05:37 From Bob Primak to Everyone:
 + Great American Eclipse
 + Explore the spectacular cosmic phenomenon of a total solar eclipse.
 + PREMIERES: 4/3/24 8pm
 +10:12:04 From John Rudy to Everyone:
 + See Mark Twain's A Connecticut Yankee in King Arthur's Court.  Chapter 6 is the eclipse
 +10:19:28 From Barry Kort to Everyone:
 + In the Lewis & Clark Expedition, they relied on a predicted eclipse that would occur when they were in the Montana Territory to calibrate their clock and fix their exact position on that day, thus improving the reliability of their map making along the journey.
 +10:33:42 From Bob Primak to Everyone:
 + On Mars, eclipses (transits) don't block out the Sun, due to the small sizes of the Martian moons.
 +10:33:54 From Mitch Wolfe to Everyone:
 + Moon "distance from Earth varies between 225,700 miles (363,300 kilometers) and 252,000 miles (405,500 kilometers)." [About 10% diff.]
 +10:36:52 From Judy & Mike Alexander to Everyone:
 + the increase in the size of the moon's orbit is due to conservation of angular momentum: because of friction due to earth- and moon-tides, the spin of the earth slows down; the orbit of the moon "compensates" to conserve the total angular momentum of earth-plus-moon.
 +10:53:04 From Bob Primak to Everyone:
 + The Northeast, from western Pennsylvania into Maine, have the best shot at seeing clear skies and limited cloud cover. Eclipse forecast for Monday, April 8, 2024.
 +10:54:59 From John Rudy to Everyone:
 + apparently there have been many ads for bogus glasses
 +10:56:09 From Bob Primak to Everyone:
 + Buying glasses in-person (or getting them for free)
 + If you'd prefer to buy a pair of approved eclipse glasses in person, the AAS recommends stopping by a Home Depot, Lowe's or Walmart to check if they have any in stock. (Some, but not all, locations sell ISO-approved eclipse glasses, according to the AAS.) Additionally, many libraries around the U.S. will be giving away free pairs of approved eclipse glasses; call your local branch
 +11:00:53 From tedpk to Everyone:
 + certain degree of unpreparedness for example the diamond ring and the less well known Bailey's beads and the Ruby necklace -- all of which relate to lunar non-spheroidicity
 +11:02:33 From tedpk to Everyone:
 + another problem with the discussion -- there is a confusion between scattering and refraction in the atmosphere
 +11:04:03 From John Rudy to Everyone:
 + best viewing is from the NASA videos
 +11:10:11 From John Rudy to Everyone:
 + blue moons roughly every 2.7 years on average.
 +11:11:08 From Steve Isenberg to Everyone:
 + But how could you see the eclipse in a plane with windows facing out the side of the plane?
 +11:11:24 From Bob Primak to Everyone:
 + An airliner can't outpace the shadow of the moon during an eclipse. So the advertised "eclipse flights" will not have much of an extended view of totality. Just, the planes will be above the clouds, so nearly certainly passengers will see the eclipse.
 +11:13:49 From John Rudy to Everyone:
 + I was on a plane flying near mt Everest.  Everyone moved to the right side of the plane to see the mountain.   So maybe 10,000 pounds moved sides.  Didn't notice any impact
 +11:14:58 From Steve Isenberg to Everyone:
 + The pilot would apply some changes to the airplane’s controls automatically to maintain level flight.
 +11:15:25 From Bob Primak to Everyone:
 + Problem is that the angle from which the sun is shining (Azimuth) is at a somewhat inconvenient angle compared to flight path. From the plane’s view the sun (and thus eclipse) would be about 7 or 8 o clock when looking at a clockface. Therefore the best would be that when totality shadow starts (or right before), the plane flies in a more northern direction or even a bit northeastern so most people on board would be able to see it clearly since we would then be at a right angle towards the eclipse (9 of clock). But this requires either that the pilot is a bit flexible (like the SW pilot in 2023 who did some zig zags as spur of the moment) or needs proper flight path planning which is what Alaska airlines did.
 +11:16:20 From Bob Primak to Everyone:
 + In this flight path, the pilot does some zig-zags to let passengers on either side of the plane to have a view.
 +11:16:34 From tedpk to Everyone:
 + Airliner should get you above most of the clouds -- so it could be useful -- the SR-71 once flew along the path of totality fast enough to "make time stand still" by doubling the length of totality
 +11:17:36 From Steve Isenberg to Everyone:
 + But the stars would come out during totality, like they do at night
 +11:19:56 From John Rudy to Everyone:
 + Anecdotally, I just heard there was a spike in births 9 months after the Chicago Cubs won the World Series.  Might the same be true with eclipses.   Or is this bogus?  Probably
 +11:21:01 From Bob Primak to Everyone:
 + A nova, not comet, will be present possibly during this eclipse.
 +11:21:38 From Bob Primak to Everyone:
 + About the Cubs and births, yes this was a local legend. Don't know about "eclipse babies".
 +11:22:50 From Mitch Wolfe to Everyone:
 + Some of the speaker's slides are from https://www.greatamericaneclipse.com/ that has a lot of related materials.

 +11:19:09 From Barry Kort to Everyone:
 + Much of the Computer Museum artifacts when to the comparable museum in San Jose CA.
 +11:19:56 From Barry Kort to Everyone:
 + Boston Museum of Science has a small room with some of the artifacts.
 +11:21:43 From Larry W to Everyone:
 + The nautical museum was shut down ~1970 during the anti-war protests. I don't know if ever reopened.
 +11:23:16 From Stephen Quatrano to Everyone:
 + I believe there is still an extensive collection of nautical devices, designs and artifacts in the museum.  They were indeed a core of the old museum.  I don’t know if they are in the new displays.

 +10:22:31 From tedpk to Everyone:
 + 1 word of caution -- myocarditis
 +10:38:27 From Bob Primak to Everyone:
 + Moderna's RSV vaccine is an mRNA vaccine.
 +10:41:47 From tedpk to Everyone:
 + Unfortunately -- there is at least some of the "inverse astronomers' paradigm" i.e. -- All sheep in Scotland are black" -- you can't say doing in parallel is the same as doing in series
 +10:47:18 From Bob Primak to Everyone:
 + From the very beginning, we now could conclude it would have been better if public health officials had never promised to "contain" COVID-19. They should from the very beginning have been forthcoming about the transition from a pandemic to an endemic virus.
 +10:48:32 From Bob Primak to Everyone:
 + But hindsight is always better than foresight, especially with public policy decisions.
 +10:51:35 From Bob Primak to Everyone:
 + The remarks about vaccines preventing Long COVID make a lot of assumptions, some of which could be challenged successfully.
 +11:20:37 From Barry Kort to Everyone:
 + A few weeks ago, CVS alerted me that the newest booster shots had just become available.  Can anyone say more about what’s the story with this newest vaccine version?
 +11:31:03 From Judy & Mike Alexander to Everyone:
 + Researchers and authorities had actually hoped to contain covid-19.  However, the behavior of significant parts of the  public (combined with anti-vaxx propaganda) undermined efforts to contain the virus.
 +11:34:30 From tedpk to Everyone:
 + Another key point:  The "Spanish Flu" of 100 years ago -- was qualitatively different than all the Flu Pandemics since -- highly transmissible, triggered s
