What is the newest installment of 'Random Thoughts' on Physics Forums?

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").

Why does greek letters look like little insects? For example you see $$\xi \\ \zeta$$

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!

And somehow Spain is called " Land of Rabbits" ??

Fight the real enemy:
Webpages that open a new tab when you click on something. After a few hours I have some 100+ tabs open and need to spend like a minute to go back and forth.

I waited for the bathroom for 25 minutes until I realized the guy I thought was in line before me was just some weird guy hanging in front of the bathroom for no apparent reason.

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?

 

[WWGD]

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.

Two weeks, all inclusive. Why not?

In some countries you will get a bill for that.

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.

"Yes."

I will change my shopping strategy these days. Instead of battling about a box of pasta or some rice, I will wait near the cash registers for people who have forgotten something and run back in the market to fill my cart with the goods they have collected. All at one place these times, namely other people's carts! You can find everything.

Not so sure. She sat right next to me, tried the charger which did not work ; we had a short exchange she could have built on if she wished and then never said an additonal word for the next hour or so. But maybe she just did a poor job of it.

Edit. Just remembering : She did ask me, when leaving, about the fresh hot_ meister 42. Guess that's what she wanted all along ;).

Ok, yes, it's Wilson's theorem: p is prime. Then in (p-1)(p-2)...(2)(1). Only one class can be its own inverse. Then we can pair the other elements into multiplicative inverses. Then $(p-1)(p-2)...2.1= (p-1)(1)(a)(a^{-1})(b)(b ^{-1})...=(-1)(1)...(1)=-1$ , one of the 3 things I remembered from undergrad number theory ( or any other number theory )

Trying to explain to this guy: no the median cannot have half the values in the data set smaller than it and the other half larger...because , together with the median, you would end up with two halves ...PLUS THE MEDIAN.

That reminds me of the British politician who said he wanted all schools to be classified as "good"; the criterion for "good" was "above average".
