Happy Pi Day – 3/14/2019

pi.png

Before there was a PI key on our Bowmar Brains, many of us would approximate the value of PI using the formula 355/113. Some of us also memorized the first nine digits of Pi – 3.14159265 and input that into our calculators. Either way, the result would be off by less than 1 part per million, good enough for most applications short of space launches.

Scientific American has this offering about How Much Pi Do You Need?:

You might have observed Pi Day on March 14. It gets its name from 3.14, the first three digits of the ratio of a circle’s circumference to its diameter. Always on the lookout for excuses to eat pie, some geeky math types also celebrate the number on July 22. The fraction 22/7 has a value of 3.142857, so it has the same first three digits as pi.

Both 3.14 and 22/7 are approximations of pi, so the two days deserve the same title. In fact, 22/7 is closer to pi than 3.14 is. So if you’re an aspiring pedant, you can choose to celebrate July 22 as Pi Day and March 14 as Not Quite as Close to Pi Day. (Either way, you’ll enjoy more pie.) But what does it mean to be an approximation of pi—and why does it matter?

This interesting article goes on to discuss how many decimal places of PI accuracy are needed for space operations, navigation (GPS) and quantum mechanics.

Classic 1935 Ford Sedan

Classic 1935 Ford Sedan

Damsel captured this photo of a classic old Ford V8 this morning on our way back from the “environmental services” facility (a.k.a. dump) on the west side of town. I saw this guy the other day when I was getting ready to leave the chiropractor’s office. I had a camera then, but the classic went by before I could grab and shoot. I’m glad that we saw it again today. It’s a beauty.

We went to the dump to dispose of a mattress that we bought when we first moved into the house. The mattress was our first place to sleep until we took our time to acquire the house furnishings as the first year here went by. Now, the 8-year old mattress has seen better days and needed to be replaced with a new one.

The new mattress is similar to the one we got for the RV last year. Same brand but a queen instead of king size. The new mattress is intended to help me get over the lower back problems I have been having since mid-February. The visits to the chiropractor have helped a lot, but we’re still not a hundred percent on being able to function normally.

I’ve had back problems since I was a young man, but it usually would heal quickly and get back to normal, Not so, as a septuagenarian. It takes time and visits to the chiropractor now, but it will get better soon. And a new memory foam mattress will help too, I’m sure.

Rosemary Farm

Bee Gathering Nectar

When we originally had the landscapers plant our yard along the back slope above the RV drive, they installed about fifty or sixty one-gallon rosemary shrubs with an irrigation system. The shrubs have been there for over seven years now, and have grown to mostly cover what once was bare slope behind the house.

I took this photo (click to enlarge) of a bee browsing some of the tiny flowers on the shrubs which have been blooming most of the winter. I can’t hear the buzzing anymore (tinnitus), but Damsel says the bees are quite loud as they busily gather nectar. Now, when the hummingbirds come by to do the same thing, I can hear them just fine.

When we need herbal rosemary for a recipe, we have no further to look than out behind the retaining wall on the north side of the RV drive. Damsel will send me out there with a pair of shears to snip off a couple of the freshly grown stems from one of the many bushes. I take the stems inside, wash them and pull the needles from the woody part. Damsel will either mince the needles or use them whole, depending on the recipe.

More on the Rosemary Herb from Wikipedia:

Rosmarinus officinalis, commonly known as rosemary, is a woody, perennial herb with fragrant, evergreen, needle-like leaves and white, pink, purple, or blue flowers, native to the Mediterranean region.

It is a member of the mint family Lamiaceae, which includes many other herbs. The name “rosemary” derives from the Latin for “dew” (ros) and “sea” (marinus), or “dew of the sea”. The plant is also sometimes called anthos, from an ancient Greek word meaning “flower.” Rosemary has a fibrous root system.

Rosmarinus officinalis is one of 2–4 species in the genus Rosmarinus. The other species most often recognized is the closely related, Rosmarinus eriocalyx, of the Maghreb of Africa and Iberia. The name of ros marinus is the plant’s ancient name in classical Latin. Elizabeth Kent noted in her Flora Domestica (1823), “The botanical name of this plant is compounded of two Latin words, signifying Sea-dew; and indeed Rosemary thrives best by the sea.” The name of the genus was applied by the 18th-century naturalist and founding taxonomist Carl Linnaeus.

My only observations regarding the text above is that (a) we’re a long way from the sea and (b) we don’t get much in the way of dew in the desert. I guess that the Rosemary herb likes it hot (it does get hot here), tolerates mild cold (rarely below freezing) and depends on the irrigation system we have here for moisture. And, clearly, the bees and hummingbirds pollinate them to their mutual benefit.

Limoncello Day 2019

Limoncello Day

Today was the day for bottling (Mason jars, actually) the finished Limoncello product that Damsel put away last December. The intermediate step was completed to remove the lemon rinds and add sweetener in January, so after maturing, the product was finally ready for putting up today, if not in bottles but in Mason Jars.

I don’t have any photos of this year’s lemon harvest in late November, but it was certainly as large as the haul we made in the lemon harvest of 2015. Our little dwarf lemon tree has reliably produced since we put it in the “Orchard” in 2011.

From Wikipedia:

Limoncello is an Italian lemon liqueur mainly produced in Southern Italy. In northern Italy, the liqueur is often referred to instead as limoncino. It is also a popular homemade liqueur, with various recipes available online and in print.

Although there is debate about the exact origin of the drink, it is at least one hundred years old

Visitors to our humble abode are usually given one or two bottles or jars of our brew. We also carry some with us when we’re on the road in the motorhome to give to friends and acquaintances. Sorry, we can’t ship it since it’s against USPS rules and other carriers don’t want it either. You will just have to come and get it or wait until we drive by for a visit.

New Glass for the Canon T6i and SL1 Cameras

Canon SL1 and EF-S 18-135 mm LensEarlier this month, Tam wrote about trying different glass to replace a zoom lens with not-so-great performance. That post gave us the idea that we too might benefit from lens upgrades for our two Canons – Damsel’s is an EOS Rebel T6i and mine (shown at right) is an EOS Rebel SL1 – both DSLR cameras.

Since the stock lens that came with both cameras was a zoom with a focal length range of 18 mm -55 mm, we decided in getting a better lens with the same starting focal length and stretching the maximum focal length out to 135 mm.

I took the above image of the SL1 with the EF-S 18-135 Lens attached with my little Kodak FZ152 Pocket Camera. Click on the image to enlarge.

Although we haven’t put the new optics through extensive evaluation, we see that the performance is pretty good. I went out this morning to get a few pictures to see how the performance was in general. The following two images of the RV and a hummingbird demonstrate the extreme wide and narrow focal length performance. Click on either image to enlarge.

18 mm zoom 135 mm zoom

As we put the new lenses into use we should get a feel for how the new optics performance will be. Just from today, I can generally see that the Image Stabilizer does an effective job of keeping the camera steady and I can’t readily detect a lot of chromatic aberration at maximum zoom.

We hope everyone had good St. Valentines and Presidents Days.

IRS 2018 Tax Return Filed – Almost

irs_logo.pngWhen the new tax rates came into effect in early 2018, we did our spreadsheet analysis to try and pinpoint the correct withholding to use for the remainder of the tax year. I think we did pretty well with the withholding although we got a bit more in the deductions due to a couple of things: 1) we were especially generous this year with a couple of new pro-2A foundations* and 2) we paid the vehicle tax on the motorhome for 2019 in advance when we were upgrading to the W7GD call plates. All this resulted in a modest over-withholding to the tune of getting a good chunk back from the Feds and a small amount from the state. For the latter, our contributions to the Arizona Private Education Scholarship Fund completely eliminates any state income tax liability and are also deductible under 501(c)(3).

So, now all that is left to do is the actual filing; on-line for the Fed and via mail for the state. Since I only got the last of the 1099s today and because of an unusual circumstance involving class-action litigation from which we received a modest sum, I want to go over the numbers one more time before pulling the big handle.

So, that’s just about it for the 2018 tax fiasco. I am going to adjust the 2019 withholding spreadsheet since the Damsel will now start to get a small pension from her previous employer. We are still waiting for those figures to come in for us to account for them.

* Arizona Citizens Defense League Foundation and Gun Owners of America Foundation, both 501(c)(3) charities.

UPDATE 02/06/2019: Our refund was posted in the account today, less than ten days from the time we filed. The Feds seem to have the process worked out. Not so much Arizona, That refund is forecast to be deposited on or about the 11th of February. That’s still a lot faster than the old days.

Diet Support Kitchen Gagetry

VeggieSpize Spiralizer

One of the things we most lamented about when we started on our diet last October was giving up pasta. For years, we have enjoyed dishes with all those carbohydrates and all the adverse effects they may have been having on our metabolic systems.

Now that we are on our reduced carbs diets and have been for about three months, we see our results taking place. Damsel is losing a little weight but more importantly, is reducing her blood glucose (she will be tested for that soon at the clinic). I have lost about twelve pounds and two belt notches since the start.

And all the while, we have been enjoying our new cooking lifestyle with substitutes for those things we thought we couldn’t live without. Instead of mashed potatoes, we have mashed butternut squash. Instead of noodles, we have enjoyed Zucchini Noodles (Zoodles) and that brings us to the gadget in the photo.

The photo shows the spiralizer cranking out zucchini noodles. It is a VeggieSpize Spiral Slicer available from Amazon. Damsel and I used it for the first time last week to prepare Zoodles to be served with her homemade low carb pesto.

You can buy prepared zoodles and other veggie or tofu products already packaged in the store, but the drawbacks there are 1) cost and 2) preservatives and other additives. Packaged zoodles in the size that correspond to one spiral cut zucchini is about $3.00. To do it yourself as in the photo is about $0.55 in cost and you know what’s in the final product.

As far as spiral-cut veggies being a substitute for pasta, they do the trick; zoodles, like spaghetti, actually take on the flavors of the sauces and are of no special value other than to transport to your taste buds. The Pesto Zoodles made a nice side for some Filet Mignon steaks we had last week.
