all arithmetic is based on counting in some form or another: addition is counting in a group of counts; subtraction is addition in reverse; multiplication is repetitive additions; division is multiple subtraction. The addition and multiplication tables can be built from counting in a dozen minutes or so; I would have my students doing that every day until they could just fill them in from memory.
I really have no idea why memorizing addition and multiplication tables is out of favor; it works and gives a solid foundation for higher math. I used to be able to watch numbers updating at regular intervals and use that to tune a PID, and it was all based on knowing mult. tables; I doubt a ā5 x 8 + 40 + 1 x 8 = 48ā-trained person could do that. Do I want a nurse calculating my medicine dose to be like that? I donāt think so.
I need them for far, but not that badly. I can cope, and even drive, without glasses.
But - for mid-vision, like dashboards and computer monitors, I canāt wear bifocals or reading glasses, I have to buy trifocals or keep taking them off every 12 seconds to see the monitor.
I got in the habit of trifocals because pilots can NOT wear bifocals, we had to wear single prescription or trifocals to read the instruments. Too bad Iām too old, and wouldnāt pass the physical, to get a pilot license again. Plus I never reached my dream of being a helicopter pilot
EDIT: āPilotā is every pilot, not just commercial pilots. Cessnaās included
God Dammit:
Cant believe you made me actually look that one up.
The exact number of matches in a box, such as 37, is primarily driven by manufacturing standards, packaging efficiency, and regional market variations, rather than a specific psychological or mathematical reason related to the number 37 itself.
Here is a breakdown of why this number might occur:
Manufacturing and Packaging: The number of matches often corresponds to how many can be efficiently and compactly packed into a standard-sized box by automated machinery. Counts can vary between 20 and 50 matches for small boxes, and up to hundreds for larger ākitchenā matchboxes.
Average Contents: Manufacturers often list an āaverage contentā on the box. The actual count in any single box may vary slightly due to minor fluctuations in the automated packing process. For example, a box might state āAverage contents: 40ā but one specific box might contain 37 or 41 matches.
Regional Standards and Brands: The common count differs by brand and country. In the US, for instance, Diamond Green Light matches are typically sold in boxes of 32. In other regions, counts of 40 or 50 are common.
Perception of Randomness: The number 37 is sometimes noted in psychology and mathematics as a number that people disproportionately choose when asked to pick a ārandomā number, due to its prime nature and lack of strong cultural associations. However, this is a general human bias and not the reason for the specific quantity of a commercial product like matches.
In short, the number 37 in a matchbox is likely a result of practical manufacturing and packaging decisions specific to that product line and brand.
Manā¦. I saved up my money, talked my wife into it, did all my research and two years later called to sign up for the classesā¦ come to find out two months before I called the school went out of business, next closets one was 6 hours away
I still have my dadās E6B somewhere in a box. I actually did start working on my private pilots license many years ago. I completed all the class lessons, but decided to put my money towards a down payment on a house, instead of paying for the actual flight timesā¦.of course I bought the house and got laid off 14 days after I closedā¦.so maybe trying to finish my pilotās license was the better option. Now days with young kids and, the COL being much higher here in NZ, Iām not sure Iāll ever end up getting m private pilots license, but it is what it is. Maybe when the kids are older and Iām retired.
I joined the Air Force when I was 18 just to become a helicopter pilot.
Turns out they donāt ask until you get to Lackland AFB if you are allergic to eggs. Vaccines back then were all incubated in duck eggs and an allergic person would die within 30 minutes of getting all the shots, so I got sent home.
BTW - that allergy finally went away and I can eat as many eggs as I want now.
I thought if anyone would recognize sarcasm you would be the first.
Also, cereal and other boxes saying 18oz means 90% of the boxes will have a minimum of 18oz. For filling they adjust their dispenser scale up to maybe 21oz to get the 90% 18oz minimum. So most boxes are actually over 18oz.

I actually considered joining the marines when I was 17, but I was turned down because I used to sleep walk as a child, and I have a strange ligament issue. Later I tried the coast guard and got turned down for the same reasons (which I assumed would happen but tried anyway).
But you will be the only humans still around when (not if) we have World War 3
True. When I had only been here maybe 2-3 months I think it was the civil war in Syria broke out, or was ramping up or something. Some friends on Facebook got into this big debate about it, and involvement from other countries including the US and Russia, etc.
One person asked āwhat are we supposed to do move to an island in the middle of nowhere and ignore the rest of the worldā, I just replied āOn itā and added nothing else at all to the conversation.
Its going to happen, maybe after my lifetime but I guarantee its going to happen
I think NZ is the only or one of the only countries that export more food than you consume, living there I would live on the water (so I could fish) and have enough solar power to keep off the grid and you would be set if anything happened
When I lived in SC we had chickens, they were the only pets that gave you something back and the only bad thing was they stop laying after about 3-4 yearsā¦ they live to be 6-8
And before anyone says anythingā¦ no you can eat them after you name them
Chicken Little, Chicken Gumbo, Chicken Noodle and Chicken ā¦. One more cant remember
Living on the water is pretty pricey, unless you are in the middle of nowhere, but we live 8-9 miles from a few beaches. I donāt have a boat though, but Iāve been wanting to get a fishing kayak. We got solar a few years ago, got a few quotes, one should have provided enough for us to pretty much live off grid, but it was a bit out of our price range, so we didnāt go with it. We are planning down the road adding more panels and a battery and such. We went with the hybrid inverter so we could add a battery later without swapping inverters or adding in converters etc.
We donāt have a lot of land, but have a nice little garden setup and grow some stuff. We could certainly be in a better position if WW3 kicks off, but could be in a worse one as well.
Yah, I have a genset, dog and people food for awhile but its still not going to be funā¦ my wife says she wants to be right next to the bomb and get it over quick, sheās got a point, either on a island or ground zero, everyone else is going to have a bad day
I canāt believe that we are having a conversation about this in 2025 and that humans have not learned in 2000 years how to play nice
Back on the subject of analog clocks. The annual Medicare āwellness visitā includes a cognitive test for geezers like me. You are given three unrelated words to remember. Then to help you forget the words, you are asked to draw a clock face with the hands pointing to a specified time. After completing that, you are asked to remember the three words.
I asked the nurse who administered the test what was the plan for the next generation who have minimal exposure to analog timekeeping.
Like the college class at a technical school that had a broken clock so they set it to 9:11 in remembrance. Then posted it online and got royally roasted and told it was set at 8:55, not 9:11 by hundreds of adults.
