Ok, "Year-end bonus", not "Rear-end bonus", makes more sense now.

Why is the number of days in a week a prine number, unlike number of degrees in a circle or other composite?
Say I want to shave every 3rd day . No matter what weekday I start, I won't be able to use the same days of the week because 7 is prime. If I shave Monday, then I also shave Thursday, then Sunday. And then Wednesday.

Same reason as 17 year cicadas. It is to evade the beard predators.

Are we lucky that we have a moon with an orbital period with a low number of convenient sized divisors? 28 days can only be divided by 2, 4, 7 or 14. If it orbited every 40 days or something then some countries would have gone for 8 day weeks and others for 10.

$3 \nmid 28$

Blame the Babylonians and the Semitics. But there is a solution for you. Since you cannot return to the days when moon orbited Earth faster, maybe you can wait until it is far enough that it takes $30$ days. Then you can introduce a week of $6$ days.

Done, we'll wait for that. I like practical solutions ;).

Talk about practical solutions. Note to self: Ask one question at a time when texting. If you ask 2 or more,
you may receive an answer for each but the order of the reply may not match the order of the questions.

"Gimme your lunch money OR I'll beat you up"

An example of the bullyin' OR.

"Gimme your lunch money OR I'll beat you up"

An example of the bullyin' OR.

But that's an order, not a question. The question would be: "Would you consider to give me your lunch money or shall I beat you up?" in which case yes or no is still the only solution, depending on the fitness of whom has been asked.

You can design your life around some of the 300+- channel lineups and just watch tv all day. There's all- movie , channels, sports, sitcoms, variety. Kind of funny is the issue of the time you spend looking at the tv guides containing the listings; takes at least 10 minutes to cycle through the list of shows in 300+ channels.

@Klystron : there was a good book a while back: Politically Correct bedtime stories. A bit exaggerated but funny I thought.

I don't know what's more worrisone: that I mixed Nostradamus with Houdini in a story I was telling or that either no one noticed or at least did not bother to tell me.

They didn't bother because, although they knew such criticism would put you in an awkward spot, they predicted you'd get out of it.

I just ordered something from Amazon paying extra for "one-day delivery" which they promise will be delivered on ... Wednesday 4th March. Given that today is 1st March, I make that at least 3 days, or at least 2 working days. Perhaps they have resurrected the old joke that "one-day delivery" means "it will be delivered one day" (as in the old Kodak joke "one day my prints will come").

They were running out of ink and that's what came up when trying to run it on paper.

It's the cover up that gets them in trouble:
It seems this lady was kicked out of a plane for lighting a match ...so that no one would notice she had farted. Nice balancing act. Hmm, do I blow up the plane killing everyone , including myself or do I embarrass myself for 2 minutes to people I will never see again who will forget about it by tomorrow? Ok, where are my matches?

I was feeling good about myself when someone asked me a Math question and I gave them a reasonably good answer. But then he asked me two more I had no idea about, to remind me how little I know: are there infinitely many primes in the Fibonacci? Is there , for every prime p, a Fibonacci that is a multiple of p?

Your interlocutor must have been a rabbit rancher; er..., farmer; er... wrangler. The best rabbit wranglers only want to raise pedigree prime Fibonacci bunnies. Motto inscribed over each hutch:

! El Conejo mas fino !​

​

("Only the finest bunnies!")​

​

Spoiler: explanation

Many beginning math textbooks introduce Fibonacci sequence using rabbit generations. Recent translations of old textbooks derived from Fibonacci's writings do not mention rabbits.

Spoiler: explanation

Fibonnaci was likely proficient in contemporary Spanish and Arabic.

The name of our best-before-date here is: "date up to which it is durable at least" Of course we have only one word "Mindesthaltbarkeitsdatum", MHD.

But no matter how often I complained, what they print on the bottles of beer is always wrong!

I was at a supermarket. According to what I have seen I can assure you that the end is near!

Sometimes I find it very funny that Hendrik Antoon Lorentz said “lengths gets shortened, time runs slow when we move relative to ether” only for maintaining the existence of ether.

Why just for saving the concept of ether he doubted the nature of space and time (which are more basic and foundational than ether) ?

 

[Ibix]

It depends when he said that. The Lorentz transforms were developed in the early 1890s, and spacetime wasn't introduced until 1908, by Minkowski. And relativity fatally damages Newtonian gravity, a mess that wasn't resolved until general relativity, published in 1915. And even then, one shouldn't accept a new theory without a decent try at defending the old - that would be almost as foolish as refusing to abandon the old when the defence becomes unreasonable.

Interesting: 7-1-9-3 , list of last digits of the first 300,000 prime numbers, by frequency order. Edit: primes larger than 5.

 

[fresh_42]

And how many have 0,2,4,5,6,8?

 

[Ibix]

Nitpick: shouldn't 5 and 2 be there at the end?

Fair-enough: primes larger than 5. Will edit.

It seems reasonable that emails that ask you to enter your original email when unsubscribing are just asking to check whether you're an actual recipient and their random spamming hit a target.

I've never understood electromagnetic radiation. I've read a bit of the Wiki on it, but I don't get it yet.

Every atom in the universe emits EMR unless in absolute zero state. You're emitting it right now in infrared.

If photons are emitted from electrons (dropping a state), I would have thought they must be a subatomic component of one.

Then how can the electrons in a star emit a constant wave of photons at the speed of light for billions of years?

An electron cannot contain infinite photons so the oscillation/excitation of an electron is propagating through a field as apposed to releasing a physical component of itself. A photon is a wave in the field which would mean it isn't a single unit (confused).

So anything above absolute zero oscillates a field which we perceive as heat and light.

I'm probably way off but this logic let's me sleep atm. I've tried to Google papers on it, but stop when I see the fluster cuck of formulas that may as well be Egyptian hieroglyphs.

Scam alert? Lady at coffee shop asks to borrow my phone charger " for an emergency". Charger does not work for her phone. She then proceeds to chow down on a sandwich, pastry and coffee for some 45 minutes, not apparently attending to the emergency. If you prefer to avoid false negatives takes up more thinking.
