Treatments for Rusted Metal: Rust Bullet, Cosmoline RP-342, and Others

This past month I had to deal with a hole rusted through the body of my old but serviceable car. A local body shop told me it might cost more than the car is worth to replace the rusted parts. The rust does not look like it has compromised the vehicle’s mechanical integrity (a real concern, since today’s cars rely on the body sheet metal for strength), but I don’t want it to go further.

Being a (retired) chemical engineer, I read up on ways to deal with rusting metal – especially how to arrest the progress of rust. Here I will share what I have learned about several types of coatings. I hope this information is of use to some readers.

Fr. Gregory Pine on the Hiddenness of God

As a scientist and as a Christian, I have pondered the question of why God does not make his existence and his purposes more visually obvious to us humans.  I can understand why scientists who are agnostics stay agnostics: where is the physical proof that a Being, who is in some sense personal, created and sustains the universe or has some particular purposes for my life? I (naively) think that if I were the Supreme Being that I might maintain flaming letters over every national capital saying “Seek God”. Or something like that.

Bill Johnson’s Talk at Bethel Church After His Wife Beni Died

Although we live a continent away from Bethel Church in Redding, California, we feel an ongoing connection there. We have attended talks on the East coast when Bethel staff members have traveled out this way, and we benefit from their ongoing presentations on podcasts and YouTube.

We made a month-long pilgrimage to Redding in 2018 to check the church out in more detail. I tend to be somewhat skeptical (“Is this too good to be true?”), so I made a point while I was there to schmooze with lower-level staffers to try to get the inside scoop. I found a consistent picture of integrity and good-willed service at all levels. I wrote up my 2018 visit on this blog here:   Prayer for Healing at Bethel Church.   

One thing that Bethel is known for is a hopefulness about supernatural healing. Managing expectations for answers to prayers for healing is tricky. I do not claim to have found the perfect balance here. In most churches, when prayers are offered for someone’s healing, there is a (spoken or unspoken) caveat clause of, “If it be thy will.” That lowers expectations, which in turn mitigates disappointment when (as so often happens), the ailment simply runs its natural course.  I think that is reasonable theology, and as a practical matter everyone, even the holiest saint, eventually dies of something; that seems to be just the way things are.

A Logarithmic Map of the Observable Universe, From Earth to Edge

Pablo Budassi has created a logarithmic map of the entire known universe, that shows the distances and relative sizes of objects above the earth’s surface. I think you will find it a worthwhile use of your 30 seconds of attention to click on the link below, scroll to the bottom to start down at the earth’s surface (the image quality at the link is much better than I can convey in these snips here):

And  then scroll your way up and up, through planets and stars to galaxies (not every star and every galaxy is shown, of course) and galaxy clusters:

Raspberry Pi 400 Review: A $100 Desktop PC?

The Raspberry Pi 400 is billed as a complete desktop PC for under $100 ($99.99). Is this for real, considering the cheapest regular computers are around $300, not including paying for Word and Excel? I am interested in low-cost technology which might benefit less-developed countries, so I decided to look into this.

New Finds from Tanis Fossil Site Shed Light on the Demise of Dinosaurs and Vindicate “Amateur” Fossil-Hunter

Three years ago the world of paleontology was rocked by the claim of a brash young maverick to have found a site which captured a physical record of events from the very day 66 million years ago that a giant meteorite impacted the earth and (eventually) killed off all the dinosaurs. Robert DePalma had the perseverance and the insight to realize that the initially unpromising location (just some crumbly fish fossils in mudstone) that he took over from another fossil hunter was a unique paleontological site. DePalma and co-workers published a PNAS paper proposing that the Chicxulub meteorite which struck near what is now the Yucatan Peninsula of Mexico caused an earthquake which in turn caused massive waves of water to surge up a creek at the so-called Tanis site in what is now western North Dakota.

The surges deposited several feet of mud onto sandbars in the creek. It also deposited a number of hapless fish onto the sandbars, where the fish eventually perished. The meteorite impact blasted tons of melted rock into the air; little glassy congealed blobs (“tektites”) rained down across western North America for the next several hours. As it happened, some of those glassy pellets were falling in North Dakota just as the mud layers were being deposited on the sandbars from the water surges. Finding these pellets, and even their little impact holes, in the middle of these mud layers confirmed that these layers were in fact deposited a few hours after the meteorite impact. We described these 2019 findings in Tanis Site: The Day the Dinosaur-Killing Asteroid Hit, and discussed how they support the mainstream science view that the earth is billions of years old and that dinosaurs died out millions of years ago.

Three Different Polls Show Recent Rapid Decline of Religion in America

Three polls (by Gallup, Pew, and Barna) were published in 2021 which tracked church membership and religious affiliation among Americans. I will pick out a couple of salient plots from each poll, and comment at the end on their significance. The linked references can provide details on polling methodology.

Faith Meets Agricultural Science: “Pfumvudza” Planting Technique Brings Hope to Zimbabwe

Zimbabwe, formerly known as Rhodesia, lies just north of South Africa and Botswana. In 1980, the white minority government was replaced by majority rule. Rhodesia/Zimbabwe was known as the “breadbasket of Africa”, and even the “jewel of Africa”, because of its natural resources and prosperity. This arrangement with good agricultural production lasted for some twenty years after the 1980 regime change.

Birth of a New Farming Method

Brian Oldreive is a native Zimbabwean. A star cricket player as a young man, he moved on to become a successful tobacco farmer. In 1978, he had a born-again Christian experience, and became convinced (given the harm that tobacco causes) that he should no longer grow tobacco. When he tried to switch to food crops like corn (called maize in Africa), using standard agricultural practices, he could not make a go of it. He ended up losing his farm due to his moral stand on growing tobacco. He went to work for another large farm, but even there it was a struggle to grow food at a profit. Soil was eroding and crop yields were falling.

Trends in Young Earth Creationism, from Prof. Joel Duff

Joel Duff is a professor of biology at the University of Akron, Ohio who blogs at Naturalis Historia. He monitors trends in the world of Young Earth (YE) creationism, and posts occasional articles on his blog. Last year I summarized some of the data he gathered on the finances and the social media reach of major YE creationist organizations.

In 2021 he published four articles on the state of YE creationism. The final installment is Young-Earth Creationism in 2021- Part 4: Final Thoughts and New Creationism Resources. A recurring theme in his work is the emergence of what he calls “The New Creationists”. This is a (mainly) younger generation of YE creationists, not formally part of the old guard organizations such as Institute for Creation Research, Creation Ministries International, or Ken Ham’s Answers in Genesis. Some names here include:

How to Earn 7% in U.S. I-Series Savings Bond or 9% Stable Interest in a Crypto Account

Inflation is up to about 7%, which means that the cash in your bank account or savings account or money market fund (all which pay almost nothing) is losing that much value in a year. That has spurred me to find other places to park cash.

There are plenty of high-yielding stocks (e.g., ARCC, ACRE stock symbols) which pay 7% or more, but their value can flop up and down. That is bad if the stock is down when you want to retrieve your money to make some other use of it. Therefore, I looked for things that have stable values while still paying high interest. The two I have found recently are the I-series U.S. savings bonds, and  “stablecoin” cryptocurrencies.
