https://www.the74million.org/ Interesting find ... (for me). M.

http://www.signalharbor.com/73.html Ham radio! Another one of those hobbies that seems to have vanished from the face of the earth (of course, it hasn't). Also, apart from 73 being a "emirp" of 37 (a prime whose mirror iage is also a prime), both 37 and 73 are star numbers...

https://en.wikipedia.org/wiki/Rule_of_72 We live and learn ... at least, I cannot help but feeling that way almost every day ... M.

An iconic band that dispanded (as far as their original line-up goes) in 1971: Booker T. and the M.G.'s This was their last single ... And this is ... Green Onions ... M.

70 is the smallest weird number. Not useful in any way, but strange (and rare) enough to be interesting. There are lots of other references - but I found this the weirdest ;) M.

You saw that one coming, didn't you ;) M.

https://www.magnumphotos.com/theme/1968/ Definitely worth a look - or three ... M.

I found out that 67 is a "lucky prime"; since we can all do with as many concepts of luck as we can muster, I think I'm allowed to expose you to this pretty nerdy one: https://en.wikipedia.org/wiki/Lucky_number#Lucky_prime And for the rest of us, here's some music developing ... arbitrarily...

A classic Rock'n'Roll version of a legendary song: Here's the original (as far as I know): And finally, something nostalgic for us German speakers (I'm not even that much into this kind of music, but there are worse songs about getting older - and fear not, I'll knock it off with the...

Now, this was ... sort of creepy. I thought it wouldn't be a big deal, so I first researched "65" and stumbled over pretty weird stuff quite quickly (including a whole ecosystem of programming training ... I won't go into that, but it was impressive and depressing at the same time). So I thought...

Start Date Aug 3, 2020 End Date Aug 24, 2020 The 36th Cameraderie Challenge theme is: dominant colours. My apologies if the theme had been covered before, which I can't find. As usual, this challenge will consider originality, technical merit, and artistic vision. In my mind, the most...

That was easy ... M.

"63 Up" is latest film in the "7 Up" documentary series by Michael Apted, probably better known as the director of "Gorky Park". He visited the same people every seven years and made a documentary series out of that; so this was the ninth time he did such a film - over 56 years. Talk about...

For the record: I chose this for the music and the title, not the message. Still, a bit of background: https://www.jpost.com/Israel-News/Culture/Full-Trunk-shows-us-what-they-got-514074 https://www.jpost.com/j-spot/full-trunk-pulls-us-out-of-dire-mire-633244 I felt I had to research this a...

We've now doubled our continuous days of posting since switching to a rolling model - and the "Day to Day" challenge WILL continue past the end of July, of course. As or references, this may be one for the baseball fans, dramatised in the 2001 movie "61*", but here's a slightly different angle...

Final day of this year's SiJy challenge - thanks so much for participating and hanging in there; and to those who found it impossible to see this through, thanks for your contributions as well! And if you want to ponder "final days", I really, really recommend "Good Omens" (by Neil Gaiman and...

https://en.wikipedia.org/wiki/60_(number)#/media/File:Icosidodecahedron.png Love it ... (Be sure to click the link to see the image I'm referring to!) And something else to binge-watch if you've got the power: https://www.cbs.com/shows/60_minutes/ It's not free in any meaningful sense...

"59" turned out to be a tough nut to crack (if you aren't into psychedelic synth music, which I *am* not ... and chemistry is out for today), but here's something that may please some of us: https://duesenbergusa.com/guitars/59er M.

28 is a so-called "perfect" number: Add up all of its proper divisors except itself (i.e. take its "aliquot sum" - nice little piece of Latin there), and you get the number itself: 1+2+4+7+14=28 A good reason for a perfect turnout, everyone :) (N.B. I could have used this earlier ... 28 is not...

Another one of those more insightful songs - and besides, an egotist self-reflecting is always a sight to see ... M.

https://en.wikipedia.org/wiki/NGC_47 You have to read the entry to get the "pun". Let's just say that zeal doesn't guarantee success ... (No deeper insights here, just a random lead ...) M.

https://en.wikipedia.org/wiki/Passenger_57 Maybe something to watch again? M.

https://en.wikipedia.org/wiki/Aubrey_holes A little pre-history ... M.

That was the first thing to pop up when I researched "55": https://www.55places.com/ It's definitely not what I was after to be honest, but it offers a certain angle on things - there's an important debate to be had right there ... However, if you don't want to reflect on it, here's a much...

Wha ... ??? https://commons.wikimedia.org/wiki/File:Genji_chapter_symbols_groupings_of_5_elements.svg Okay, now that's so highly condensed it's seriously over my head; but it still looks intriguing; so's the story referred by these symbols: The Tale of Genji, an ancient Japanese novel ...

I knew I had seen that number before ... https://en.wikipedia.org/wiki/The_Love_Bug :) M.

52 - the number of weeks in a year, but more importantly, the number of named cards in a full deck of cards ... M.

https://en.wikipedia.org/wiki/Area_51#/media/File:Wfm_x51_area51_warningsign.jpg Area 51 ... epicenter of long debunked conspiracy theories ... but a place with a very interesting history nonetheless. Oh, and a (good!) photograph of a "photography prohibited" sign is always worth a look or...

I found the information solid and to the point, but the background music ... is just irritating ... Here's the institution behind this: https://initiatives.iitgn.ac.in/ccl/ Very thought-provoking (though the music certainly isn't ...). M.

Day 50 meets (for some) day 111 - nice cross-over. I won't reference that book everyone thinks about if they hear "50"; take a look at this instead (hint: It's not what you think!): https://www.investopedia.com/terms/n/niftyfifty.asp It just goes to show that everything depends on your point...

The first (and only) square number whose digits *are* themselves squares (7x7=49; 4=2x2, 9=3x3). Also, the smallest number of fields you could play Tafl games on (Brandubh, to be precise), though usually, it's everything from 81 to 169 fields (9x9 to 13x13 - 11x11 make it Hnefatafl; there even...

And on we go ... M.

Something I was only dimly aware of (as many of us, I assume): https://www.eda.admin.ch/agenda2030/en/home/agenda-2030/die-17-ziele-fuer-eine-nachhaltige-entwicklung.html This is actually the Swiss government's information page on this - interesting ... Especially if you have a little insight...

(This was the first episode of the "Rare Earth" series ...) To back things up: https://www.britannica.com/event/47-ronin M.

D'you know ... I just couldn't find anything worth your while to say about 46? So, without further ado ... let's keep it up. M.

I fumbled the preparations for today ... So, let's just take it from here ... M.

Could not see a Day 15 thread so I jumped the gun... Matt feel free to edit this as you wish...

I didn't want to talk about guns - and frankly don't know enough to do that, anyway ... M.

Always worth a commemoration (and still the system I compare everything else against!): https://www.four-thirds.org/en/microft/ And yes, especially at the this very moment ... M. P.S. In honour of this, I'll use the Panasonic GF1 with the 20mm f/1.7 today.

Son carrying father's torch ... M.

This is an easy one - except for picking the entertaining link ... well, let's just make it a couple ... M.

Start Date July 10, 2020 End Date July 31, 2020 This Cameraderie 35th Challenge theme is: REFLECTED. As usual, this challenge will consider originality, technical merit, and artistic vision. As photographers, many of us are interested in, fascinated by or occasionally obsessed by the nature...

As promised ... ;) M.

Something completely unrelated I didn't know the correct answer to (why is Windows 10 called "10"?); here's the answer. https://www.techradar.com/news/software/operating-systems/what-comes-next-after-windows-10-1299629 -> N.B. Nerd stuff, surely - not worth your attention if you're not into...

I'll merge the two numbering concepts soon and settle on the "Day to Day" count - but "101" was too good to pass up, especially since I really didn't know where the term came from; here's the research behind the explanation ...

Just for the record, this is the 99th day since we started the whole daily exercise - which means ... we'll have a celebration tomorrow. In the meantime, this ... M.

https://en.wikipedia.org/wiki/NGC_2169#/media/File:NGC_2169.jpg Neat. M.

Six squared on the 6th - now, that was easy :cool: M.

35mm - Barnack's baby sure made it. :) (Sorry for the witticism - but I saved you from some quite bleak observations about 1935 (and a meme "avant la lettre", but I'll save that for another day.) M.

34 defines the four-by-four magic square ... http://mathsmagic.in/magic-square-4-x-41.html M.
