Watch this video about tomorrow’s solar eclipse.

How rare is the April 2024 #eclipse?

Predicting the next total eclipse is not a simple math problem, having several independent factors. Yet as the video mentions, an ancient Babylonian tablet tracked all the solar eclipses from 347 to 258 BCE.

It makes me wonder about the wisdom of some ancient civilizations. What did they know, that has been lost to us? From medicines to space to science, what intelligence was previously discovered and has since needed to be rediscovered, relearned.

And what did the ancients know that we still don’t know?

The sci-fi try

Leave a reply

I don’t usually listen to fictional books during the school year. I usually wait for the breaks, in summer, winter, and March, to pick up a ‘fun’ book. But I started a sci-fi that is about the moon breaking up from a mysterious and sudden catastrophic event. The earth then has roughly 2 years to get as large a community into space before being destroyed by moon debris crashing into earth at a rate that makes earth a fiery hell.

The technical aspects of the book are great. It’s easy to nerd out on the science and to imagine the challenges the survivors must face. The only issue I’m having with the book is that it doesn’t share the loss of life in a compassionate way. The story lacks heart.

It tries, but fails to put loss of life in a way that lets the reader feel grief over the loss. The author is more interested in the science than the humanity. He makes attempts but they aren’t great. Yet the book is still good. I’m only 1/3 of the way through and it will be the Christmas break before I get through it. I’ll let the shortcomings go and enjoy nerding out on the science and the idea of the future of humanity and civilization resting on an ad hoc space colony.

Not all stories need to be perfect to be enjoyable. Sometimes you have to make choices. This book lets me geek out without getting too heavy into the devastation of the entire earth… and I’m just one generation in. From what I understand the story spans a few thousand years. I won’t be putting the story down just because it feels a little clinical in how it deals with death. Because ultimately (so far) it’s a story about survival in desperate times, and under dire circumstances, and I’m hooked on finding out what this dystopian future holds.

I chose a science fiction, not a romance novel, and I’m getting a good dose of both science and fiction. For those interested, the book is Neil Stephenson’s Seveneves.

Geology, Astrology, and Prophecy

Leave a reply

There are some major geological disturbances and volcano eruptions in Italy, Japan, and at any moment potentially Iceland. We live on a volatile planet with harsh weather conditions, earthquakes, and occasionally tsunamis and volcanic eruptions. Right now there is a lot of geologic activity. This happens in cycles, and it seems that we are on a very active cycle right now. That’s geology. That’s science.

What it’s not is ‘the end of times’, it’s not the end of the world as we know it as a human race, although it may feel like so to anyone living near one of these eruptions. And I don’t mean to downplay worst case scenarios. One of the volcanoes in Italy that is active is what’s known as a super volcano, like the one under Yellowstone National Park. A large eruption of a super volcano can devastate vast areas of land and upset the weather of the world for years.

It could get really ugly.

But this isn’t some biblical prophecy. It’s not an angry God upset with the failings of humanity, and it’s not the coming of the apocalypse.

It’s science. It’s Mother Earth doing what Mother Earth has done for millions of years. It’s cyclical, but on a geological scale that spans chunks of time that extend far longer than civilizations tend to survive.

Tying these geological events to ancient scripture is like tying your dating life to tarot cards, or waiting for the alignment of stars to make a career move… foolish. The earth isn’t angry, it’s seismically active. It isn’t punishing mankind, it is going through natural processes.

We build houses and cities on flood plains, and in tornado zones, and on the sides, and potential lava flows, of volcanoes. If harsh weather systems or major geological disturbances happen in these danger zones, it is disruptive to the lives of those living close by. If a super volcano erupts the whole world could be affected. Again, that’s science.

This could end up being a series of small eruptions, and it could be a massive global disruption… What it’s not is written in scriptures, holy texts, or the result of the alignment of stars. I’d hope that we have evolved past superstitious caveman and can recognize the difference.

1.5 billion beats

Leave a reply

I just started a new audio book, Scale, by Geoffrey West. I learned that almost all life forms have an average of about 1.5 billion heartbeats in their lives. Mice have faster heart rates, and die sooner as a result. Turtles and whales live over 100 years with their slower heartbeats. But fast or slow, it seems animals end up with about the same number of beats if they live a full life.

I find statistics like this fascinating. How is it that this is a constant when so many other factors come into play, and when so many evolutionary traits went in different directions? Trunks, blow holes, shells, horns, fins, arms, wings, marsupial tails, all evolve with different purposes, but our many sized hearts all give our different species the same amount of beats.

We may not have the same appendages, we may be all different sizes and shapes, and we all have different amount of time on this planet… but all our mechanical clocks tick the same number of times. Amazing!

Asimov’s Robot Visions

Leave a reply

I’m listening to Isaac Asimov’s book, Robot Visions on Audible. Short stories that center around his Three Laws of Robotics (Asimov’s 3 Laws).

• The First Law: A robot may not injure a human being or, through inaction, allow a human being to come to harm.

• The Second Law: A robot must obey the orders given it by human beings except where such orders would conflict with the First Law.

• The Third Law: A robot must protect its own existence as long as such protection does not conflict with the First or Second Law.

These short stories all focus on ways that these laws can go wrong, or perhaps awry is the better term. There are a few things that make these stories insightful but they are also very dated. The early ones were written in the 1940’s and the conventions of the time, including conversational language and sexist undertones, are blatantly exposed as ‘olde’.

It also seems that Asimov made 2 assumptions worth thinking about: First that all robots and Artificial Intelligence would be constructed with the 3 laws at the core of all intelligence built into these machines. Many, many science fiction stories that followed also use these laws. However creators of Large Language Models like Chat GPT are struggling to figure out what guard rails to put on their AI to prevent it from acting maliciously when meeting sometimes scrupulous human requests.

Secondly, a few of the stories include a Robopsychologist, that’s right, a person (always female) who is an expert in the psychology of robots. There would be psychologists whose sole purpose would be to get inside the minds of robots.

Asimov was openly concerned with AI, specifically robots, acting badly, endangering humans, and even following our instructors too literally and with undesirable consequences. But he thought his 3 laws was a good start. Perhaps they are but they are just a start. And with new AI’s coming out with more computing power, more training, and less restrictions, I think Asimov’s concerns may prove prophetic.

The guard rails are off and there is no telling what unexpected consequences and results we will see in the coming months and years.

Blind spot

Leave a reply

I saw a Neil deGrasse Tyson video where he described our galaxy as thinner than a pancake. He said it is more like a crepe. Our galaxy is more than 100 times long as it is wide. One result of this is that it limits our ability to see the universe.

We can’t look beyond our galaxy along its length. There are so many stars in our own galaxy that they prevent us from seeing anything beyond it along this thin plane. Essentially our galaxy creates a blind spot for our visible universe.

That doesn’t mean there isn’t a lot to see along this axis. We can look at our closest neighbouring solar systems and explore our own galaxy, we just can’t see beyond our galaxy nearly as well and as clearly as when we view the universe from an angle other than along the plane of our flat crepe galaxy.

It’s interesting because while this flat shape creates a bit of a blind spot for us, it also makes a lot of the universe easier to see, because our galaxy does not get in the way of a lot of the sky. If our universe was more spherical, it would be a greater impairment to the universe beyond. Our blind spot creates an advantage elsewhere.

There is a metaphor there for our own personal blind spots. Blind spots might limit what we see in some areas, but how do they allow us to see more in others? We observe our world from eye level. We can learn more about our surroundings by seeing a bird’s eye view, but it wouldn’t be an advantage for us if that was the only view we had.

We all have blind spots, I just wonder what insightful perspectives they give us compared to if we didn’t have them?

Bad questions

Leave a reply

One of the dumbest tropes in education is that, ‘There is no such thing as a bad question’. Yes, yes there is. Yes there are. There are many bad questions. We live in a world filled with bad questions.

Why are people still asking if climate change is real? Why do people still question if the world is flat? Why do people still question evolution and want creationism taught in classrooms?

Because we live in a world where bad questions are asked and people respond to them. With each justification there is a rebuttal, and when millions of people hear the dumb, illogical, misleading, and inaccurate rebuttals some of them will believe these bad ideas.

Bad ideas spread from debating bad questions.

Good questions deserve debate. Bad questions should be ignored… or redirected. ‘Is climate change real’ is a dumb question based on a bad idea. A better question is, ‘We know humans are impacting the climate, what can be done to reduce that impact?’ Spending time rationalizing the first question is literally giving the question too much power, and the ignorant responses an opportunity to be shared.

It’s worth saying this again, it’s the problem we face today across many fields, spreading through news and social media… and when we participate, we are part of the problem:

Bad ideas spread from debating bad questions.

So the next time someone tells you there is no such thing as a bad question, you might want to disagree, just don’t waste too much time debating the point.

Trips to the moon

Leave a reply

India just soft landed a spacecraft on the moon. It’s the first craft to successfully land in the South Pole region, where craters that never see sunlight might be hiding frozen water. Reading this article made me realize that, while landing a human on the moon hasn’t been done in decades, the ‘race to the moon’ has been alive and well since then.

I searched for ‘missions to the moon’ and found this massive list on Wikipedia. It was shocking to see how many there have been, and how many of those have been failures. I’m not sure what rock I’ve been living under but I had no idea that so many countries were part of this space race.

I hope this craft finds frozen water. It would be an amazing discovery. And with a human return to the moon planned by NASA in the next few years, I’ll be watching news about moon landings a lot more now. We certainly are living in fascinating times and I’m excited to learn more about our universe beyond the earth’s atmosphere from flights like this and from telescopes like the James Webb telescope. There is still so much we have to learn.

Superconductors and aliens

Leave a reply

What a crazy bit of news out the last couple days! Ambient temperature and pressure superconductors could change the world and so too could the admission that we are not alone in the universe. Both of these are things that deserve scrutiny and further evidence. That said, what an exciting time to be alive.

Room temperature superconductivity has been a physics Nobel Prize waiting to happen. So much of the energy we use is lost in transmission. Furthermore, this invention will make nuclear fusion containable, without significant cost and dangers of a breach because superconductors used for plasma containment won’t need to sustain unbelievably cold temperatures next to an extremely hot process. In other words, energy is about to get a lot easier to produce and share.

As for aliens, I think there is enough evidence to say that there are flying vehicles that do things human-made vehicles can’t. Whether aliens are in these vehicles or if they are run remotely (they pull some high g-force moves that would destroy a human), they are definitely not human made. So what are they, and who/what made them?

I’m mixing my enthusiasm with a dose of scepticism, but unlike most other news stories, these are two I’m going to be watching!

Kindness really matters

Leave a reply

I wrote about a kind act yesterday, and today I got this image as a Facebook memory:

I believe that kindness can be contagious, it can become memidemic (my word for a positive epidemic). Kindness resonates, it has a frequency that when put out in the world will be picked up by others nearby. Just like a tuning fork of the same frequency will start to vibrate if another tuning fork, similarly tuned, is vibrating nearby, so too does kindness resonate.

Choose kindness today. Even if the kindness is not returned, know that it will resonate and you will be contributing in making the world a better place.
