In Sputnik’s Orbit
A few thoughts to tide you over…
Hi everybody! I know I’ve been way too quiet of late, and I thought I’d pop in to give a little update–and a lesson in perseverance.
First, I sold two more stories (you are the first to know). One, my 2020 Jim Baen contest winner, sold to Analog. The other sold to Galaxy’s Edge after being my second Jim Baen finalist way back in…I’d have to look up the year.
The renowned mathematician Paul Erdos, when asked how old he was, used to answer “2 billion years”. His reason was “when I was born, the Earth was known to be 2.5 billion years old; now it’s known to be 4.5 billion years old; therefore, I must be 2 billion years old!”
With respect to Mr. Erdos, that’s a load of BS.
Paul Erdos was born in 1913, the first year radiometic dating was proposed by Boltwood. At that time, most scientists would have quoted late 19th century estimates of between 50 million and 100 million years unless they were up on the discovery of radium and the heat it produced (and the effect that had on estimates based on heat dissipation), and then they would have admitted that no one could know, but many hundreds of millions of years at least.
Boltwood later determined that the 26 geological samples he was working with were between 410 million and 2.2 billion years old—which only meant Earth had to be at least that old.
So when Paul Erdos was born, Earth was “known” to be at least 410 million years old, though most science curricula were still teaching “tens of millions.”
Radiometric dating was used in 1921—in an impromptu effort at a conference—to establish an informal consensus that Earth was “a few billion years old,” and in 1927, Arthur Holmes’ “The Age of the Earth” argued from radioactive analysis that certain strata must be at least 1.2 billion years old, but he was not attempting to accurately date the Earth but to convince geologists that they should take radiometric dating seriously and that it could and must be reconciled with other methods.
In 1931, the National Academy of Science convened a “committee on geologic time,” which issued a bulletin (#80) declaring that radiometric methods were the only reliable means of measuring the age of Earth, but even by 1949, their annual report only declared “the age of the Earth appears to be “ about 3.35 billion years. By that time, Erdos had been bouncing around university research positions for a decade. Today, lead-uranium and lead-lead radiometric dating have been used to definitively date the Earth–or more precisely, the moment of crystalization of the oldest rocks on Earth and near space, to 4.543 billion years, plus or minus 1%.
So no, Erdos was not 2 billion years old, though it’s possible he was a person who didn’t pay a great deal of attention to geophysical news. More likely, he was just making a joke. A Hungarian by birth, he also used to start his talks by saying with “I’m going to speak to you in the international language of science: Bad English”
Below is my reply to a person who reached out through my website to explain why he didn’t need to see my video about anti-viral masks because he “already had covid for a few minutes and is immune for life,” and anyway the disease is a hoax, etc., etc. I didn’t write this to address that person (who is no doubt so deep in the cult of political theater as to be beyond all hope) but to address for the greater good his oft-repeated misapprehensions. And now that I’ve done that, it’s off to work I go…’
When I started writing seriously back in 2011, I knew the last thing I needed was to start coming home every day from my corporate desk job and spend hours more behind a desk, so instead I learned my craft standing in the bedroom, typing on a little Acer Netbook perched high atop a tall chest of drawers. That worked well enough
A Quiet Place had a lot of buzz when it came out in 2018, but though I’m a huge fan of both Emily Blunt and John Krasinsky, for various reasons, I never saw it. So the other night, after a hiatus due to an injury, I was looking for scifi to watch while burning calories on my treadmill, and Netflix offered it up. But after five or ten minutes, I’d had enough. Here’s why.
One of the reasons I started my Patreon page was to defray the cost of certain items and services needed to advance my writing career so I can spend more time writing. The impetus for the change was a teleprompter I started tinkering together over the holidays.
Over the years, I’ve cobbled together all sorts of photographic gear, tools, gizmos, and software–but there is always a consideration of what in business school is called “the make or buy decision.” These days, when I start to build or repair or clean or fabricate, a proverbial birdie rests on my shoulder, singing “you should be writing, you should be writing.”
Building a teleprompter looked to be a poor use of my time. Cobbling together a usable lighting rig was an even poorer use of my time. Recording my first couple of videos using only the little Canon Powershot I use for appearances–and syncing the video up with audio from an external recorder was….Jimminy Cricket! Like going back to the days of 8mm movie film and splicing cuts with cellophane tape!
But if I’m going to use video to help build an audience, I need a teleprompter so I don’t have to waste vast quantities of time and blood pressure memorizing scripts. A teleprompter is a device that lets the camera shoot through a piece of glass reflecting text out to the performer. It lets you address the audience directly without constantly looking up and down and loosing your place or looking like you on a Zoom meeting.
Like a lot of things, the fundamental technology isn’t as exotic as it used to be. For one thing, instead of extraordinarily special purpose optics to reverse the text, you can now just install an app on a tablet. And with millions of YouTubers creating a new low-end audio visual market, the special glass that gives teleprompters a bright, clear image isn’t as special purpose as it used to be.
Even so, teleprompters are expensive, and the only ones in my price range are only big enough for a cell phone–and my eyesight isn’t that good. Finally, about the time I made my Patreon account, I found a deal on a tablet sized ultra simple teleprompter for only $75 and put my order in….and never got it. As of today, it’s still officially backordered, but I suspect the deal was just a little too good. The glass alone is worth that price.
So…with both my Patreon and YouTube channels slowly growing stale, I decided to finish up my DIY job and harvest the glass out of the Chinese discount model if it ever actually arrives. And so I give you (Drum roll please), the Tinkerator 2000, DIY Teleprompter!
Featuring solid pine, superglue, a broken certificate frame, odds and ends from the garage that I should have thrown out years ago but as soon as you throw it away you’ll realize the one perfect thing you could have used it for, and such hardware as I could not forgo or improvise but could order online during a pandemic.
The Tinkerator 2000 folds flat for storage, features Velcro attached stays to guard against accidental glass shattering collapse, and a luxurious old T-shirt light shade resting atop a deep, Velcro secured top support to guard against stray movie lights.
