This is one of my favorites to share. It’s a 3D engine with raytracing with no VBA scripting - all of the calculations are done internally with spreadsheet math.
Good Excel users think themselves better than a beginner. Great Excel users think themselves somewhere between Intermediate and Advanced. Excel Masters, and I know one who placed in that Excel data modeling competition, know they’re somewhere in the Intermediate to Advanced range.
Used for the right purposes, Excel is an extremely versatile and powerful piece of software. Is use it all the time for analyzing complex financial data and turning pivot tables into really nice looking reports. I can use VBA behind the scenes to change report scenarios while preserving the formatting. Excel is great for things like that.
It’s easy to get Into trouble though because eventually someone decides to keep a bunch of auxiliary – yet somehow very important – data in a spreadsheet. Before you know it, multiple people are being asked to maintain said data and then POOF! You now have a spreadsheet functioning as a database. It’s all downhill from there.
Per Wolfram Alpha, sulfur is 4.62 times heavier; the earth is 0.002% lithium, so it would experience a net gain of 3.62 * mass of earth * 0.00002, or 4.3e20kg. That’s 7.24e-5 times heavier, so not much in the grand scheme of things.
Note that I’m neither a chemist, a physicist, or an astronomer, so I make no guarantee that I did this right.
… Not IT approved, but well… we use an MSP, and I get to be a decision maker in the company for certain things, and just do it, because well… I can, and the company keeps me around partially for the things I do with python and sql.
I would like to say Pandas should be used for much of that excel stuff, maybe even replace it, but… Microsoft has decided to bring Python capabilities into excel, so that will likely cement them in your workflow even further:
I’ve found the selling point in not needing to open excel and click around to run the script. So often people need to do like the same three things and don’t even know how to write Python, so giving them a script to drag your file onto is a step up from excel
Recently the headlines have actually been way more “study finds something super obvious to be true that most of society took as truth without needing a study. They just lived it in their every day life”
There’s a 9 repeating 6 times in there which I’d think is a pretty rare occurrence in pi. I wonder what the longest occurrence of a repeating digit is.
Looked it up, and it’s apparently called the Feynman point after Physicist Richard Feynman (though the story behind that attribution is disputed). en.wikipedia.org/wiki/Six_nines_in_pi?wprov=sfla1
That’s fascinating. Obviously, there’s a series of repeating numbers in there, and one of the numbers would have a highest number of repeats… until further places of pi are determined and another number knocks it off… I assume there’s a repeating 1, or 2 that repeats 7 or 8 times,etc… at some point…
At work at the moment so can’t go deep into it. But I think you misunderstand what non repeating numbers mean. Of course there are repeating numbers within pi which is fine, the issue would be if ALL the digits were to simply cycle over and repeat themselves. If however there are a few trillion digits then a series of 1’s and 0’s for ever, pi is still non repeating
I did read it, I also wrote it. Wasn’t trying to put you down or anything just sharing a bit of knowledge I found interesting. I know many people (my self included at one point) assumed pi would have to include everything when that just isn’t true. Apologies if I did a bad job explaining it though
On a long enough string I’m guessing… Infinite? Pi isn’t a pattern so does it follow the same “if monkeys hade an infinite amount of time to type at a typewriter they’d type Shakespeare”
Well I thought that at first, but it has to be less than infinite since other numbers have to repeat in there as well with at least some occurrence so it’s infinite minus something, but since pi goes on infinitely, it’s obviously some high number…
From the pov of an organism in a high-oxygen atmosphere, thats true. But on a planet with little to no oxygen in the atmosphere, it would have to be added separately, the same way we add fuel
Then you find out that the lack of an ingredient results in the microbes producing the product lol.
Certain algae for example, need to be “starved” in a way that results in them switching from conventional photosynthesis that produces glucose to photosynthesis that functions to generate Hydrogen and Oxygen alone. The Oxygen is used for respiration and the Hydrogen is essentially dumped as a waste product. They can only sustain this for relatively short periods before their stockpile of carbohydrates is sufficiently depleted. Which means these bioreactors need to be cycled through a fattening phase where the algae stockpile fuel and a starvation phase where they exhaust that stockpile while producing Hydrogen.
Ive been trying to keep tabs on the literature in biochemistry, chemistry and other fields for decades. I inevitably come accross things like this from time to time. These particular articles I just googled because I dont have the bookmark for the original paper discussing Hydrogen production back in 2000.
