    Challenge! Day to Day 142

    Too offbeat to omit :biggrin: (Actually, it seems to have become kind of a YouTube meme ...) M.

    1+(1+2)+(1+3)+(1+2+4)+(1+5)+(1+2+3+6)+(1+7)+(1+2+4+8)+(1+3+9)+(1+2+5+10)+(1+11)+(1+2+3+4+6+12)+(1+13)=141 (The sum of the sums of the dividers of the first 13 positive integers is 141.) M.

    Challenge! Day to Day 140

    We've surpassed 200 shots; it'll be some time before there's another milestone, so let's just go ahead and cruise ... However, since 140 is a bit fast (less so in kilometers than miles, though), I'd say Tweets (which started at 140 characters once upon a time) deserve a mention. However, I...

    Challenge! Day to Day 139

    Completely random and unrelated, but he's always interesting to watch and listen to ... For the record: Today's our 200th consecutive day of shooting :2thumbs: M.

    Challenge! Day to Day 138

    The fifth of the prepared threads - due on Friday. We haven't had any punk for a while, so here goes ... Well ... M.

    Challenge! Day to Day 137

    The fourth of the prepared threads - due on Thursday. Researching this was quite fun ... Though going back to Caesium seemed a bit cheap, in spite of Chernobyl and radioactive boar in the Swiss Alps this year. However, 137 as a number is apparently huge in cosmology; hence this...

    Challenge! Day to Day 136

    The third of the prepared threads - due on Wednesday. https://en.wikipedia.org/wiki/WR_136 Reminded me of this ... M.

    Challenge! Day to Day 135

    The second of the prepared threads - due on Tuesday. (1+3+5)(1x3x5)=135 Neat. Also, does anyone remember him then? M.
  9. MoonMind

    Challenge! Day to Day 134

    The first of the prepared threads - due on Monday. A piece of dire history ... resolved (to the point that's possible) later. https://en.wikipedia.org/wiki/United_Nations_Security_Council_Resolution_134 M.

    Challenge! Day to Day 132

    10-10-20 > add two lines, and it all adds up ;) To show how it's done: 12+13+21+23+31+32=132 Neat. M.

    Challenge! Day to Day 131

    https://en.wikipedia.org/wiki/Iodine-131 The benefits of radioactivity ... Something we often forget. M.

    Challenge! Day to Day 130

    We start another countdown today ... Ten days until we hit 200 (on day 139 of the current challenge), so keep them coming! Other than that, I just have a sombre little factoid: It's the 500th anniversary of the first recorded public book burning in Leuven (today Belgium) for political (or, in...

    Challenge! Day to Day 129

    https://en.wikipedia.org/wiki/LZ_129_Hindenburg Horrible story, but seminal media moment all the same ... M.

    Challenge! Day to Day 128

    Not using the "128" lead into computing would have been an opportunity wasted, so it was only the question of which angle to choose ... https://en.wikipedia.org/wiki/CAST-128 M.

    Challenge! Day to Day 127

    "Prime" time again, this time with the ominous Friedman numbers ... M.

    Challenge! Day to Day 126

    Developing an idea provided by Steve (@drd1135) about "magic numbers" in nuclear physics and their implication for chemistry, more precisely the periodic table: https://en.wikipedia.org/wiki/126_(number)#In_physics In short, should element 126 be made, it is expected to be much more stable...

    |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||| <- 124 x ASCII Code 124 (Sorry, this was the only way of preventing a silly game of: "If you were a car, what car would you be?" ;)) M.

    Challenge! Day to Day 123

    Something very different today ... Shakespeare's 123rd Sonnet, from the Quarto of 1609. Rebelling against time itself ... (or himself, to stick with Shakespeare's own symbolism). If that's to sombre for you, this is actually worth a look or three (;)): M.

    Challenge! Day to Day 122

    For all who have kept shooting since we started posting daily: We've reached 183 days - so, half a year, no matter which way you cut it :2thumbs: Researching the number, I found this: https://en.wikipedia.org/wiki/Jeanne_Calment We're not quite at her level yet, but she may keep us inspired...

    Challenge! Day to Day 119

    1110111 in binary - palindromic, thus symmetrical, but not boringly uniform ... Also, the number of the next element to be created - probably in Dubna in Russia. M.

    Challenge! Day to Day 117

    https://en.wikipedia.org/wiki/Chinese_dragon#Number_nine Seeing the state the world is in, we sure could use a little luck ... (Yeah, I know it's kind of a quirky one, but I'm in no state to aspire to anything better today.) M.

    Challenge! Day to Day 116

    https://en.wikipedia.org/wiki/116th_Street_Crew Even though I'm no stranger to the history and study of organised crime, it always amazes me how intangible the mob manages to remain (seeing as we know most faces and even heads ...). M.

    Challenge! Day to Day 115

    Apart from another element I could mention (Moscovium - Mc) and few mathematical flukes, nothing I feel is worth mentioning - however, this is neat: PIE' is "115" in the modern Greek numbering system (P': 100, I': 10, E': 5) - which is too charming a conincidence to ignore 🥧 😁 M.

    Challenge! Day to Day 113

    Element 113 is Nihonium, particularly relevant to photographers since it is named in honor of Japan, home of most of the camera makers. Of course, Nikonium would have been better.

    Challenge! Day to Day 112

    https://en.wikipedia.org/wiki/112_(emergency_telephone_number) I wasn't aware of the universal importance of this (telephone) number ... And then, there was this: M.

    Challenge! Day to Day 101

    Since we're nearing the end of the Messier Objects' numberline (110 is the last one ...), here's another one, very nice ... And for the number nerds, 101 is prime in base 10 (duh ...) and base 2, palindromic in both cases - a good incentive for symmetry :) M.

    Challenge! Day to Day 95

    Anyone still remembering this sloth of an OS? https://www.theguardian.com/century/1990-1999/Story/0,6051,112728,00.html This and its descendants sent me down the GNU/Linux route ... On a totally different note, this had me scrolling madly to find out if this is actually in Switzerland ...

    Challenge! Day to Day 94

    Beautiful image ... https://en.wikipedia.org/wiki/Messier_94#/media/File:Messier_94.jpg Somewhat more comforting than having to talk about Plutonium ... :rolleyes: M.
