It was a bright and sunny day during April- May(can say, peak of summer) in a country in the northern hemisphere, near to the equator. I was wandering(on foot) through this country's vast and open land - harsh desert - and in the evening seen a strange thing - the sun was setting in the East - ...

i assume the "y'all" implies that gareth is not one person but actually a whole team of solvers
because that would make perfect sense

6:13 AM
Yep. Gareth McCauganicalTurk.
(...in the more modern sense of a crowd sourced bunch of people automating a single job, rather than in the more classical sense. I'm not suggesting that Gareth is a machine with a human hidden inside, which would raise more questions than it answered.)

Great. Now I imagine that Gareth has a twirled moustache and a turban.

Some time ago, I discovered that planet earth's sidereal rotation period equals 23 hours, 56 minutes, and 4.1 seconds (see for example this Wikipedia article). The sidereal rotation is the rotation of a celestial object around its axis. Thus, earth takes a little less than 24 hours to rotate arou...

@Sphinx I'm not sure this is really a puzzle?

And it was deemed barely a puzzle

@Alconja Yeah, sorry, I know I owe one. Soon.
@jafe In many varieties of Southern US usage, "y'all" is actually singular and you need to say something like "all y'all" if you actually want a plural.

@GarethMcCaughan All good mate. No pressure, was just idle at work and looking for something to mull on. :)

I am trying to form an algorithm to swap any two corner pieces i.e. at the end of the sequence two corners will be interchanged leaving all the other pieces undisturbed ...

Well, my friend told me that he's just visited a safari. Being toured around, he was very surprised how the guide could spot those animals so quickly. He took some pictures of the animals, anticipating to show them to me. However, when he gave me the photos, the photos are nothing like animals!...

There is a very well-known family of right triangles in Mathematics called "The Imperial triangles". Let me explain you how they are defined: We say $T_n$ is the $n$-th Imperial triangle if these two conditions are met: Its hypothenuse has length $\frac{1}{n}$ Water boils at the second-to-long...

Following the last question " What is the corner house number?" here is possibly a more challenging version. Fill in the missing house numbers on the map shown below. The area is occupied by math and language loving (crazy) residents who have come with the interesting names. There are 4 stre...

It's White to move and draw the game. What must White do? You must provide proof for your claim of what's to be done by any reasonable means. This puzzle was created by Nikita M. Plaksin, and published in Shakhmaty v SSSR in 1980. No looking up the solution please!

Each answer to a clue will consist of the titles of two works or series put together, where the last word of the first title matches the first word of the second title. Note that the word match does not have to be exact; for example, the last word of the first title might be a plural version of ...

This puzzle is a combination between a Slitherlink and a Fillomino. You should put a number in each square and draw a single closed loop over the grid such that the following properties are satisfied: All the shaded squares should contain 1, 2 or 3, and the number should equal the number of si...

I planning a surprise trip for my husband's 40th. He is a math geek. I am not. My plan is to tell him in a series of riddles/puzzles that he needs to figure out. We are going to LA to see his favourite singer. Anyway we are going Oct 25/6 (haven't 100% settled on the date) to Oct 30, 2019. So...

@GarethMcCaughan Clearly POP STAR = younger singer. This uses an indirect anagram (indicated by "Turning") of A\$ (Australian dollar = down Cash) + PRO (in favour of) + TP (tepee, which looks like A)

ah, we're on the Bad Solutions thing again, I see.
(No, that is not the answer.)

Man, and I was so sure.
