My amazing Saturn photo? Big Brother will test at home; Upcoming online AAS and APS Meetings in the first quarter of 2021; More cloudy nights means less observing and more physics discussion

 Greetings from Palmia Observatory,

Well here we are hoping for some clear weather to make more of our Saturn-Titan orbit measurements, but the clouds are everywhere wo we can report on some latest findings about COVID-19 at home, rapid testing, some upcoming astronomy and physics meetings and some discussion about infinities in classical electromagnetism.

So, in keeping with my friend, Tom's image of Jupiter-Saturn conjunction, as seen in Wisconsin, here is my amazing image of Saturn on December 28.  The forecast for the 29th is a bit better.

In response to a question from Science Nerd and onetime Theatre Impresario, Scott, I looked up the possibility of getting one of the low cost, at home, rapid COVID-19 tests that we discussed in the last post of Dec 27, 2020.  Well, it just happens that the Abbott at home test received emergency use authorization on Dec 20, so I had to look up the details.  The test kit costs $25 and you can do the test at home, but only under the supervision and inspection of a proctor, who will be witnessing and guiding the test on your webcam.  Hmm, it sounds more like Big Brother watching than the low cost version we were hoping for.  There are competing interests between the individual just wanting to evaluate their own health and the public control of the pandemic.  Anyway, here is the screenshot from my iPhone that describes how the test will be conducted after you affirm you are who you say you are and scan your drivers license.  The good news about this smartphone app is that if you test negative, you get sort of a "digital passport" that you are not contagious as of the date of the test.  Thanks for the question, Scott!

So, since the weather is not cooperating for nighttime observing, we will finish off this post with a partial calendar for upcoming AAS and APS meetings in the new year and with some comments about the infinities in classical electromagnetism.

The next meeting of the American Astronomical Society (AAS) is happening, online, from January 10 - 15, 2021.  So be sure to check out the details and sign up.  The meeting is for professional astronomers, but even astronomer wannabes can find plenty of interesting presentations.  The details about the nature of the online meeting can be found at: https://aas.org/meetings/aas237.  Remember if you meet the qualifications to be an amateur astronomer, you can get in for a reduced fee.

Don't miss the AAS 237th (online) meeting, Jan 10-15 (Source: https://aas.org/meetings/aas237)

There are two upcoming meetings of the American Physical Society that may be of interest to all of the physicist wannabes out there.  The first meeting, "The March Meeting" is conducted online on March 15 - 19, 2021.  This meeting primarily covers condensed matter physics.  You can check out the details and sign up at: https://march.aps.org/

The second main APS Meeting is "The April Meeting" is conducted, online, on April 17 - 20, 2021.  This meeting is primary for those interested in astrophysics, general relativity,  and cosmology.  You can check out the details and sign up at: https://april.aps.org/

Don't miss the APS April (online) meeting, Apr 17-20 (Source: https://april.aps.org/)

Ok, finally back to the discussion about infinities that come up in the study of physics.  Visionary Physicist, Dr. Don, was reviewing the nature of inertia and asked me to look at chapter 28 of Feynman's "Lectures on Physics."  All physicist wannabes will have these volumes at the ready.

Feynman's classic red book series (Source: R. Feynman, "Lectures on Physics)

My interest in our discussion was how even in calculations involving classical electromagnetism result in infinity.  This is not good because it means that something has broken down.  Consider this example for calculating the energy of the electric field around a charged particle.  The main point to keep in mind is that the energy goes up as the reciprocal of the radius, which goes to infinity as the radius approaches zero, which is what is assumed for the notion of a point.

Calculating the energy around a point charge (Source: Feynman, "Lectures on Physics")
Calculating the energy around a point charge (Source: Feynman, "Lectures on Physics")

To get around these infinities, one approach is to not include point charges and to consider the electron, for example, as a wave or a field.  In quantum field theory this approach has been very fruitful in getting rid of the infinities and make progress with a better way of understanding nature.

This approach going from classical descriptions to quantum field descriptions of nature is covered very well in this textbook.  This is one of the first textbooks that I found that explained the original problem and then went into how the introduction of fields and other concepts led to a solution of the problem.

Great review of the transition from classical to quantum fields

But the solution to the initial problem requires us to study more deeply about the quantum path integral approach under the general topic of "the theory of renormalization."  Hmm, this sounds like it is going to be hard because the snippet of text below says you have to first of all work through all the material in chapters 4 through 15 just to get up to chapter 16 where the renormalization theory is presented.  Ok, ok, the life of the physicist wannabe is just one chapter after another.  Thanks for the insight, Don!

So, that is it for what probably is the last post of 2020, unless the clouds go away.  This turns out to be the 471st post on the blogging journey.  What a year this has been. Now we end this year with hope of better things to come.  Happy new year everyone!

Until next time, here from our burrow, stay safe, as we recover more of our freedom,

What? How can this be the 400th post on this blog?; Upcoming SpaceX Starlink launch; Nanoscale structure and possibility of thermal diodes; Gentle introductions to gauge theory; Maybe jazz is the connection and answer?

Greetings from Palmia Observatory

Well, happy Valentine's Day to all of you star struck wannabes!  In this post we cover the latest news from SpaceX, consider how nanoscale structures lead to the possibility of thermal diodes, delve into the nature of gauge theory and end up with how our night out with jazz might be the secret of understanding physics.

Hooray, blind pointing of camera captured some Starlinks; Upcoming planetary caves conference in San Antonio; Get your dark physics in the paradise of Guadaloupe; Starship launch NET March 16

Greetings from Palmia Observatory

Well we have had some success in blind pointing the camera at the sky and captured some Starlinks satellites.  We will review some upcoming conferences and finish off with some comments and recommendation for Sean Carroll's "Mysteries of Modern Physics."

No sunspots this week; More on EHT imaging of M87 black hole shadow; How big would a black hole with Milky Way mass be?

Greetings from Palmia Observatory

Well with no sunspots  this week we had a chance to sit in on another presentation about the Event Horizon Telescope (EHT) and the shadow of the black hole in M87, which called for more homework on how radio interferometer arrays work to produce images.

Looking for another constellation of Starlink satellites; Hmm, saw some flashes, took some photos, but no string of pearls

Greetings from Palmia Observatory

Well, SpaceX launched another constellation of Starlink satellites early Wednesday morning, so let's go out on this Saturday evening and see if we can spot any on their predicted pass over Orange County.

Hey, the SoHO app shows some sunspots on our "quiet" sun; Darn clouds! Hooray, finally can see one sunspot; Need more focal length for more detail

Greetings from Palmia Observatory

Well, just by chance this week I scanned the SoHO smart phone app, and it showed a couple of sunspots.  Wow, this was pretty unusual since I had not seen any spots at all for the last several weeks I looked.

Blind pointing attempt to photograph Starlinks; Radio Astronomy and chiral carbon molecules; High School Cubesats to measure pulsar x-rays

Greetings from Palmia Observatory

Well we are back from our Hawaii adventure at the 235h AAS meeting where I demonstrated that I was still capable of playing hooky from school!  Anyway, now back in OC we attended a couple of lectures one on using cubesats to train students and do science and another on radio astronomy and can comment on them.

More from AAS 235; Stellar Interferometry; Betelgeuse; Fast Radio Bursts; Ancient Polynesian Mariners; Rainbows, Luaus and Fire Dances

Greetings from Palmia Observatory

Well, the 235th AAS meeting in Hawaii is drawing to a close, but we can provide a few summaries of sessions on stellar imaging, using spectroscopy to measure stellar mass inflow and outflow, fast radio bursts, and how ancient Hawaiian navigators discovered the stars after losing sight of the land.

More AAS 235th meeting; No Dark Energy? TMT Protests; Bright satellites and astronomy; Planetary Science; History of Astronomy; Playing hooky in the Hawaiian sun!

Greetings from Palmia Observatory

Well it is another day in Hawaii at the 235th AAS meeting and the temptation to play hooky is very, very strong.  Not because the meeting is not interesting, but because of the natural beauty of Hawaii.
