Stu Savory ;-) School report for Stu Savory
Eunoia, who is a grumpy, overeducated, facetious, multilingual naturalised German, blatantly opinionated, old (1944-vintage), amateur cryptologist, computer consultant, atheist, flying instructor, bulldog-lover, Porsche-driver, textbook-writer and blogger living in the foothills south of the northern German plains. Not too shy to reveal his true name or even whereabouts, he blogs his opinions, and humour and rants irregularly. Stubbornly he clings to his beliefs, e.g. that Faith does not give answers, it only prevents you doing any goddamn questioning. You are as atheist as he is. When you understand why you don't believe in all the other gods, you will know why he does not believe in yours.

Oh, and after the death of his old bulldog, Kosmo, he also has a new bulldog, Clara, since September 2018 :-)

Favourite Flyer?

Writing from New Zealand, Barbara-Anne asks "I see you have been flying for some 50 years now. So what is your favourite flyer, and why?"

Well, lass, that has changed over the years as the type of flying changed for me. So here are some old photos, hence excuse the lack of their quality.

I started off in the early seventies learning to fly Rogallo kites (glide ratio about 1:3) in the hills of Santa Monica (USA). Back in Germany I liked the Adler hangglider (ratio 1:8?) in the hang-gliding school in the Sauerland hills.

So bought this yellow one, which I later crashed in a stall. Yellow is better seen by rescuers than green if you crash into the foliage :-(

Moving on to regular gliders/sailplanes, I found I was not very good at finding thermals. So the glider I most enjoyed was this pre-WW2 trainer, an SG38 (glide ratio 1:10). You sit right out in the front, have NO instruments, and are catapulted off a hillside by a dozen friends running down the hill pulling a rubber rope ;-)

Moving on to powered planes, with about 200 hours of experience, at first I enjoyed aerobatics in a small biplane single-seater, a Pitts. The Pitts can pull 9G and push -6, but I could only manage +6/-3G. Then I met SWMBO so needed more seats.

Meanwhile I had tried about 20 different types from MS880 via C172 to a Bonanza, but then settled for this 1969 PA28-140. Four seats (3 if I filled the long range tanks), fixed undercarriage, fixed pitch prop, thinking "what isn't there can't go wrong". It served us well for a quarter century all around Europe :-)

Photo by his passanger Rosemary when I was formating on Anton's Bölkow 208.

I only flew twins if somebody else was paying - you need separate ratings for each twin type. My favourite was Alan's Piper Aerostar, a quite fast 6 seater, which I preferred to the Cessna 310 and the MU2. Photo of the full IFR office.

Only disadvantages I found, the offset pedals and forward CG (Centre of Gravity).

So today is Valentine's Day.

Here's one kid's opinion . . .

American blogger lady Cop Car has mentioned that both her husband and daughter bang their heads on the door frame when getting into her car. Imagine if she had a european car instead of a US car . . .

BTW, here, headbangers are heavy metal music fans.

Cop Car wrote " Aww, Stu, the only topless vehicle I’ve ever owned was a Junker bi-plane – and that was just part ownership. The ungainly sizes of vehicles on American roads are ridiculous. (Thanks for the link.)" I thought you had a share in a Bücker Jungman????
Cop Car replied " Thanks for catching my mental blip, Stu. I can’t imagine where my brain was when I wrote that - and can’t find the email that I sent...." Junkers = corrugated aluminium low-wing monoplane, Bücker Jungman = wood and fabric biplane like this one shown below. P.S. Yes, I DO know one should not touch ANY prop in case the magnetos are on, it's a bad habit I have from having to hand-start this beast.

How big is a Megaton bomb?

Talking to Ed (USA) last week, he referred to my 2022 photo of Fat Man, the Nagasaki atom bomb, shown below and asked "If a 21 kiloton atom bomb is that big, how much bigger is a megaton atom bomb?"

This is a misapprehension. The Fat Man had a big external sheet steel casing, so that any possible machine gun bullets from a potential japanese Zero fighter plane would not get through to damage the delicate atom bomb mechanism which depended upon retaining its 5 ft. diameter spherical shape. There is no atom bomb bigger than about 50 kilotons.

The bigger yield nukes are all hydrogen bombs (aka Thermonuclear bombs).

Then I realised most of my readers have never seen one, so here is a photo of the american B28 thermonuclear bomb. Much smaller as you can see, thanks to design "advances". Fits on a fighter-bomber. It has a yield upto 1.45 megatons afaik. I chose an (unclassified) photo with loading personnell for scale purposes.

I wrote about the largest possible nuke back in 2014. The smallest nukes are socalled "suitcase" nukes which fit in a backpack or were used as an Honest John warhead.

Billions of Versions... wrote " More than you ever wanted to know about all the world's nukes. (Wikipedia)." Thanks for the link Mike.

Almost, but not quite, true

So back in the sixties we were doing some chip designs and Steven was building a floating point unit, when I teased him by telling him he could test it on the identity 4 + ℼ5 = e6.

Of course both and e are transcendental numbers, going on forever and never repeating themselves so he needed a high precision to test this identity.

Now this supposed identity is almost, but not quite, true; so it took a week of debugging attempts for him to discover I was pulling his leg.

Using e.g.the calculator in Windowz I get 403,428793 for e6. And for 4 +ℼ5 I get 403,428776 ; a slight difference of about 4 parts in 100 million ;-)

Billions of Versions... wrote " You got me looking on Google where I ran into this... "How did Google calculate pi? Iwao's team used the y-cruncher program and Chudnovsky algorithm. Their calculation ran for 157 days before finding the 100-trillionth decimal place — a 0. They then verified the final numbers with the Bailey–Borwein–Plouffe formula. In total, the process used a whopping 515 TB of storage and 82 PB of I/O. Jun 9, 2022 " I thought the 31 trillion number was still good. Nope, 100 trillion by the same gal. A long while back I decided to calculate the first million digits of pi using pifast on my 386 computer. It took 36 hours." As a student I learned to recite PI to 100 places, for a beer. Now I know just 30 or so.

Blog Dewey Decimal Classification : 153
FWIW, 153 is a triangular number, meaning that you can arrange 153 items into an equilateral triangle (with 17 items on a side). It is also one of the six known truncated triangular numbers, because 1 and 15 are triangular numbers as well. It is a hexagonal number, meaning that you can distribute 153 points evenly at the corners and along the sides of a hexagon. It is the smallest 3-narcissistic number. This means it?s the sum of the cubes of its digits. It is the sum of the first five positive factorials. Yup, this is a 153-type blog. QED ;-)
