PSU math prof: Here's how to predict eclipses

Steven Bleiler, a professor of mathematics and statistics at Portland State University, explained how eclipses can be predicted by anyone using basic tools found around the house.

    We are in the process of writing a scientific paper on the mathematical tracking of Venus w/the Tzolk’in by the Mayans. For the book, we are diving into the mathematics of the Dresden Eclipse table, and this video was very informative and helped solve a problem we had. I appreciate the professor and whoever posted the video-thank you! 🙏🏼

    Why we dont have eclipse every month?

    Because the moon's orbit is note quite in the same plane as the sun/earth orbit. The new moon will cast a shadow every month, but for most months, the shadow misses the earth. It is only when the crossing is "near enough" to the earth-sun plane that we get an eclipse.

    Informative presentation, but misleading. The professor mentions that the display is not to scale, yet never mentions the true scale of the earth, moon and sun relationship (sizes and distances, e.g. the Moon is approx. 30 Earth diameters distance from the Earth) -- perhaps he could have drawn it on the whiteboard. Also, he mentioned the Moon's shadow on the Earth during a solar eclipse is only about 60 miles wide, yet doesn't explain why the Moon, which is over 2,100 miles in diameter casts a shadow only 60 miles wide. Good presentation overall, however.

    The shadow part works like if you have a lamp and a small ball. Depending on the distance of the ball to the lamp it will cast a different size shadow

    It is really sad to see a grown man such as this believing in the nonsense of the Helios religion. The Earth is not a ball and neither does it move.

    It's really sad that you missed the bit where he can use these calculations to successfully predict when eclipses are going to happen. So, if the earth "does not move" why does some mathematics that presumes the moon orbits the earth in an ellipse, the earth orbits the sun in an ellipse create accurate predictions of when eclipses will happen. Do you have some alternative math that works? Can you show they are not based on the orbital mechanics he describes? If you can't, it's time for you to reconsider what you think you know. It's not a religion anymore when you can accurately and repeatedly predict the future. It's science.

    @@curious968 Fail. Your stupid religion, that everyone got taught in the local government indoctrination center, has already been proven false. I understand you are ignorant of this fact. Eclipses have been predicted for thousands of years, because the celestial bodies move like clockwork. And this is another absolute proof that debunks the Helios religion because if the Earth is spinning, and orbiting a ball of gas existing in a vacuum, that is moving within a 'galaxy', which is moving in a universe towards the Great Attractor, then not only should we not be able to predict such things, and not only should we not have the same constellations for thousands of years of recorded history but we should not see the same stars 2 days in a row. Note the reaction - it is the proof of the indoctrination.

    @@AikenBruce It is true that you don't need a "globist" model to predict when an eclipse will come to "your" town. It happens every 54 years if it happens at all. That's good for your town. But, that's not the whole story. To get a modern prediction of an eclipse, which can predict it _anywhere_ on the planet, you need a "globist" model and some heavy duty math. There are several eclipse paths and each path repeats every 18 years. However, it is displaced by eight hours every time. So, a "globist" model predicts three times as many eclipses as simply watching the heavens does. Because ,despite your blather, we do understand orbital paths. The "globist" model also predicts how _much_ of the sun gets covered (it varies, you know) and, accordingly, how long the eclipse will last. You don't get those added details without the "globist" model. To get all that detail means you have to know that the earth orbits the sun (including detailed parameters of the elliptical orbit) and that the moon orbits the earth (ditto) and that the moon's orbit is not co-planar with the sun/earth orbital plane and how far they diverge. If you know all that, you can predict a lot more about the eclipse. Which is what we now do, quite accurately. So ,show me the flat earth version that can do all of that added stuff. You got about one fact about half right. The rest is dead wrong.
