Sky at a Glance | Recent Astronomy News & Night Sky Events – Sky & Telescope
The following are true and do not change perceptibly over an entire human lifetime.
Once you have some firm ground to stand on, you can start to remember some more basics and build. If you get confused, re-read the above and remind yourself that many things in the sky do not change!
Understand Celestial Movement by Knowing Less
Every movement of this clock is related to a naturally-occurring phenomenon. The sun, moon, and constellations are actually physically overhead the longitude physically shown on the clock. The only man-made concept is the unit of time: hours/minutes/seconds.
Within the constraints of being two-dimensional and using only concentric circle movement, the clock graphically displays celestial movement as accurately and with as much detail as possible in a way that promotes a practical mental model for the observer.
The horizons move to show the correct day and night length. They move in the correct direction to match the idea that the sun follows a longer path in the sky on longer days and shorter path on shorter days. In post-industrial time, noon is when the sun is directly overhead. This clock shows noon at the various world locations by being directly overhead the longitude. “Solar noon” is an industrial time concept.
The angle of the horizons does not directly correspond to the azimuth of the sunrise and sunset itself. For example, the sun being overhead a longitude location on Earth 100 degrees from your longitude when it rises does not mean the sun will rise 10 degrees north from east.
Two-dimensional is convenient for hanging on a wall, inexpensive to construct, can be displayed on a screen, and in reality people prefer 2D. 3D TVs never caught on. The outdoors is 3D enough.
Concentric circle movement is practical to construct and control. In addition, almost all the movement of the objects in the sky is due to the rotation of Earth.
Nature presents us with an infinity of detail that the clock could depict. Computers enable us to easily do this and most products show maximum detail. This clock selectively provides the user with just the basis required to comprehend celestial movement in order to inspire the user to abandon the technology for the outdoors and more fully appreciate natural reality.
On this clock, all objects are referenced to the observer as though the observer is standing aligned to the rotational axis of Earth. “Aligned to the rotational axis of Earth” sounds like an unnecessary complication, but it means all the objects move (almost) continuously and you can tell time of day, day length, night length, moon phase, moon rise and set, seasons, constellation and star positions, and even approximate world times, all using an intuitive mental model.
The observer is at the center of the post-industrial clock.
Notice, the gnomon of a sundial is aligned to the rotational axis of Earth. The ancients knew how to think about this. If you want to be familiar with the movement of the Earth and the relative motion of the sky, you must align with the Earth. If you accept the one complication of aligning with Earth, all else naturally falls into place.
You might say gravity is the biggest obstacle to aligning yourself to Earth’s rotational axis. True. To eliminate the gravity problem, just imagine you are on the north pole. If you were sitting on the north pole during an equinox, you would see all the objects on the clock rotating around your horizon just like they do on the clock.
Notice “rotate” means an individual object rotates, and “orbit” means an object moves in a path around another object. Objects can rotate and orbit in different planes, but because of the way the solar system was formed, rotation is mostly closely aligned with orbit. One notable example of misalignment is the tilt of Earth’s rotation relative to its orbit around the sun.
The position of the sun determines all time-related items.
The rotational position of Earth is shown by the sun appearing to move relative to the observer. The position of the sun in relation to the eastern horizon and western horizon tells the time of day.
Day length is determined by the distance the sun must travel through the sky from the eastern horizon to the western horizon. Day length is shown by the position of the two horizons. Night length is the remainder of the 24-hour period as the sun returns to the eastern horizon. The horizons move because of the tilt of Earth and its orbit around the sun.
The sun points to the season on the backdrop of the stars. The 12 Zodiac constellations are used because they are aligned with Earth’s equator and are visible from most positions on Earth. The Zodiac seasonal periods are named based on when the constellation is aligned with the sun. Ironically, it is exactly during a particular Zodiac constellation’s season that the constellation is not visible in the night sky because it is directly behind the sun.
The stars move around the observer because of the rotation of Earth, like the sun. Because of the orbit of Earth around the sun, the stars actually appear to move slightly faster than the sun. In a way, the stars “chase” the sun across the sky. Because of this, the constellation that is low on the western horizon immediately after sunset indicates the next season. The constellation will “chase” the sun down, setting because of Earth’s rotation and then each successive night set four minutes earlier until it sets with the sun.
Moon phase is determined by the position of the moon relative to the sun. The position of the moon relative to the sun is immediately apparent on the clock giving the user an intuitive mental model of moon phase. The moon rises and sets independently of the sun, so there are separate horizons for the moon.
The stars do not move relative to each other, so you can relate your favorite constellations to the Zodiac constellations to quickly know where they are if desired. The position of the Zodiac constellations on the clock are accurate relative to the observer. The observer need only adjust for latitude. If a constellation is directly overhead on the clock, it is directly south in the northern hemisphere or north in the southern hemisphere, or overhead on the equator.
Approximate world time is asking the question, “What time is it to other observers?” or “Where is the sun relative to other observers?” The user can look at the other cities on the clock and see where the sun is relative to them. If the sun is directly over another location on the clock, it is noon in that location. The sun is moving relative to other observers just like it is moving on the clock. If the sun appears directly to the side of another observer, it is near rising or near setting. If directly below, it is midnight to that observer.
Progress is a cycle.
Pre-history: humans evolved with celestial objects ruling our lives and became familiar with them. The sun and moon are encoded into our genes in our circadian rhythm.
Thousands of years: humans quantified the movement of the sun with sundials, and used charts for the phases of the moon and seasons.
Industrial Revolution: humans used rudimentary machines to club our minds to submit to rigid schedules.
Post-Industrial Clocks: humans use advanced machines to conform technology to nature and re-connect with our natural selves.
Like this clock, the gnomon of a sundial is oriented parallel to the rotational axis of the Earth. If you called this clock an “indoor sundial” you are not too far off. However, “indoor solar, lunar, and celestial fully-automated schedule” would be more accurate. Therefore, is this new? No, but is anything new? Not according to the Bible,
9 What has been is what will be, and what has been done is what will be done, and there is nothing new under the sun. 10 Is there a thing of which it is said, “See, this is new”? It has been already in the ages before us.
Life is a cycle and it is time to revisit some of our past. We now have the time and resources to do it.
Knowing what the sky looks like can certainly be done with charts, phone apps, websites, maps, but to develop a useful mental model, you need to periodically and quickly see something that is practically relatable to practical day-to-day events. This is our natural ability that was erased by industrial time. Industrial time is great for rigid old obsolete machines to cheaply give us rigid schedules, but computers enable machines to imitate nature and can enable us to re-connect with nature rather than brutally beating nature out of our minds with the incessant ticking of pendulums and gears. Computers can be better, let’s use them.

Like books, personal blogs seem to have an innate ability built-in to the medium to bring out the best in people.
Do not confuse blogs with social media.
I have been keeping this list of my friends’ websites for several years now. Many are small business sites (pillars of society), none are vanity-driven, and all of the information is thoughtful, meaningful work by people who care. All of it is good. It represents the cream of 100+ years of electronic communication. That’s a strong statement and it’s true.
If you became literate and started reading books 500 years ago after the Gutenberg Press, you got ahead. If you understand the power the internet brings to people by enabling blogs, you get ahead.

Game 2 summary with some quick tournament explanation from agadmator.
https://www.chess.com/article/view/world-chess-championship-2021
Magnus Carlsen to retire after loss to extreme learner Max Deutsch.
Norwegian Magnus Carlsen is the Tiger Woods of chess. That’s why chess has become a mainstream sport! OK, that’s extreme, neither mainstream nor sport (debate!?), but Magnus Carlsen was the youngest player to top the world FIDE rankings when he reached the top in January 2010 and he has been on top since.
Four days ago, on 24 January, Magnus Carlsen lost to 18-year-old Russian Andrey Esipenko. It was a huge upset. The tournament schedule is here and the final round is played on 31 January.
Watch the game analysis of Carlsen’s loss here.
Two days later, On 26 January, Magnus Carlsen bounced back and won his next game. Watch the game analysis here.
On 27 January, Magnus Carlsen, World #1, played World #2, American-Italian Fabiano Caruana.
Watch the game analysis here between the world’s top two players.
Chess games last several hours, and it’s chess at a level we cannot understand. However, agadmator’s Chess Channel makes the games watchable and even exciting. Here is agadmator’s website. Agadmator’s name is Antonio Radić and he is Croatian guy who is a really good amateur chess player and now comments on chess full-time.
The International Chess Federation, FIDE is the most widely-recognized governing body. (but their calendar stinks)
Magnus Carlsen’s own schedule might be the best place to follow. Other options are chess.com calendar, agadmator’s site, FIDE ratings, more … ?
Chess has a long history. We’ve heard some of the names without being able to place them. Here are some:
Paul Morphy, 1837-1884: dominated in America, then crossed the ocean and dominated in Europe.
Bobby Fischer, 1943-2008: American who won the most widely publicized chess championship of all time, the 1972 World Chess Championship considered a Cold War US versus USSR chess showdown. I have not yet seen the movie, Searching for Bobby Fischer.
Garry Kasparov, 1963-living: longest reign at top of FIDE ratings.
The chess computer Deeper Blue beat the reigning world champion in 1997, and computers have not looked back. Modern computers beat all humans at chess.
This year, being polite requires being a bit forceful. As I have said from the beginning along with most people I know, there is a no-mask zone around me. Under no circumstances, directly or indirectly, will I be the reason you are required to cover your face. Breathe free, friends.
That said, there are many people who support wearing masks. We have to have a way of dealing with it consistently. My responses all year to even an allusion to mask support have been harsh. I have even been harsh if I perceive a failure to actively resist. After having had time to cool off, my only regret is the herd mentality stampeding to “safety” behind face underwear.
Being a divisive subject, I have decided the best course of action is active listening. Therefore I will directly quote the mask support I have heard and repeat it as best I understand it.
Mask supporter: “Masks are polite.”
What I hear: “Cover your face – and I do not consider it impolite to tell someone to cover their face.”
Very well. You will be safe. Do not come within two meters of me.
Mask supporter after I suggested that businesses post whether they require masks or not: “Of course businesses can post a requirement for shirt and shoes, ‘no shirt no shoes no service,’ but masks?!? … Obviously the government has to step in and mandate that everybody wear masks in public.”
What I hear: “My fear and belief in masks supersede a business owner’s right to operate with open faces. Cover your face.”
I hear you loud and clear – so now don’t come within two meters of me.
Mask supporter during a discussion about the various prevention measures: “Come on man. Masks aren’t political. It’s science. Of course governments have to require masks.”
What I hear: “No discussion. We have all agreed that all security trumps all individual rights. Cover your face.”
Loud and clear. Keep your distance from me.
Mask supporter admitting that outdoor masking is probably a waste: “OK yeah, they probably don’t do anything outside, but we need to show we’re all together in this.”
What I hear … ? “Join my cult. We cover our faces everywhere. Cover your face if you are near me. My government will require it.”
I’m a bit confused to be honest, but you said it. Keep your distance.
Mask supporter relating mask wearing to health codes in restaurants: “So you believe people should ignore the mask mandate, which is a health code, and not wear masks? Isn’t that a slippery slope of people not following health codes?”
What I hear: “I think I’m clever. Cover your face. My government will require it.”
You are a real threat because people really will buy that line if the TV says it.
Mask supporter: “Science says cover your face.”
What I hear: “The TV says cover your face, so I do.”
Take your “science,” your science, your TV, and your mask, and shove them all up your ass … and keep your distance from me.
Having considered, the following categories apply for me:
People who actively respect a human being’s right to show their face while interacting, including whatever “risk” is involved: I appreciate your friendship more than ever.
People wearing masks. Depends who, where, and why.
People who fail to actively resist masking: I strive to be stronger. Writing about it is a form of resistance, hope this helps.
Any indirect support for any mask mandate: you are a mild threat. I am actively planning to avoid falling victim to any government you vote for.
Direct support, any enthusiasm for masking, or any in-person social pressure to wear a mask, even out of a perceived sense of duty: I will do my best to maintain two meters from you for the rest of my life.
I rarely do self-reflections, strike 1.
People are tired of COVID, strike 2.
But this is my outlet, so I’m swinging away.
Reaching the year point reminds me that at the beginning of all this I had not payed attention to any news for several years prior. I need to put this to rest so I can move on and go back to mostly ignoring the “news.” This has to be the last virus post.
With respect to prevention, all year I have done my best to stay outside when possible, ventilate when possible, do my part to slow the spread by not getting sick. Duh. The fresh air has been nice anyway. (I also jumped through the government hoops as required). I still got the virus – I think, I got a cough, fever, and lost my smell for 5 days. I’m obviously not alone. I knew I was taking chances. I predicted I would get it when I did, which is some form of success. I continued to avoid most indoor situations while I knew I was sick. Success. I didn’t clog up the hospital by requiring treatment. Success.
We all remember how we first heard of COVID-19. I received a text message from a friend on 25 January 2020 that referenced a virus in China. I responded more or less, “huh?” A few days later I remembered that a friend had returned to China (4 January) to take care of her sick father. Could it be related? I texted her. Her father had died from a lung infection in Hubei Province.
For better or worse, the pandemic consumed me. From disease history to modern disease prevention to haywire governments in 2020, I researched to the best of my ability and came to the conclusions above. While I cannot rule out most of the various conflicting explanations, the conclusions seem so common sense and the counter-arguments so outlandish that I feel irresponsible if I did not publish.
https://nathanruffing.com/president-trumps-first-100-days/
I tried to follow Trump’s first 100 days. I made an effort but alas I let it slide. Now when I read again what he actually said, I am reminded of how much the media distorts what he actually wrote.
I notice at the end of my post I said the same things four years ago that I’m saying now: turn off the TV and be local. Four years later I believe I can truly say I know a few people who have completely eliminated TV from their lives. That’s some success.
(Build Back Better? Tripling down on the slogans with not-so-hidden negative implication I guess: MAGA, BLM, … now BBB)
To Biden’s pledges. I guess two things stand out.
First, masking. I will continue to use masking as an indicator of mental illness and an indicator of people and places to avoid. Biden has declared himself the leader of the mentally ill.
Second, what little I saw from the media about Biden’s first 100 days looked like open provocation. I have to admit, this contrasts with what Biden has actually written, less dramatic, so once again the media is distorting and provoking.
Media quoting Biden: “I’m coming for you! Retaliation!”
Biden himself: “Washington DC plans to return to the usual half-truth thievery at the pace Americans are used to (plus masking attempt round two since a surprising majority of Americans seem to not value showing their faces).”
Marco Rubio nails it in 56 seconds, starting at 0:43 in the video:

This paper remains the best of 2020 on COVID:
https://academic.oup.com/cid/article/doi/10.1093/cid/ciaa939/5867798
Focus on fresh air and ventilation.
Defund DC. Repeal the 16th Amendment to the Constitution.
I’ll give myself a little more realistic task this time around since I failed to follow the details on Trump. It will be interesting to see how long Biden lasts.
Will Biden still be president on 30 April 2021? (100 days)
Probably.
Will Biden go the whole four years?
Probably not.
