If presented with an old 1970-2000 era landline phone, I can call someone by rapidly hanging up in the pattern of their phone number.

Used to do this in payphones as a kid. The numpads were disabled when no coins were inserted, effectively disabling tone dialing. But pulse dialing still worked.

I am pretty sure I could do it sans phone and only the handle, by rapidly pulling the plug out of the socket and putting it back in.

Never thought to try it when I had the chance.

Often the rj-12 handset cabling would not plug directly into the rj-11 jacks. If they did, I'd be surprised to learn they'd work on the wire as-is.

In case anyone is wondering, this is how old phones with rotary dials worked: you wound the dial to the digit you needed and the built-in mechanism would automatically wind it back; as it did it would momentarily disconnect the line as it passed each digit generating pulses that the exchange would count. If you still live somewhere where landline phones exist odds are this still works because the exchange maintains backwards compatibility with pulse dialling.

Up until about twenty years ago virtually every supermarket had a phone by the checkouts with a single pre-programmed button for a local taxi company; we used this trick all the time to call home, our mates, etc.

The "brat" in "bratwurst" doesn't come from "braten", which means to fry. It actually comes from the old German word "brät", which means finely chopped meat.

It's a loanword from the French "calque"

6

A compound word that enters another language via direct translation of its parts.
As an example, "loanword" comes from German "Lehnwort", with Lehn = loan and Wort = word.

I always just assumed this was a thing anyone could do, Is there some other name for this i can look into?

I'm convinced people that "can't" just don't know how.

It's the same movement as closing your throat off so you can open your mouth underwater, and you just push "up" past that till it puts pressure on the eustachian tubes, and the rumble is your muscle fibers contracting against that which resonates on your eardrums.

Anyone can do it, it's just hard to explain

That's a minor sound when I do it if I understand correctly. Audible but light. I can flex the muscles in my jaw/tongue as one would to attempt to pop ears, but pushing out from the back of the mouth and pulling my jaw backwards. I think it slightly restricts blood flow and makes it turbulent past the ear. Sounds like pulsar tinnitus (probably not relatable) but constant as long as I hold it.

5

Yeah, that's it.

I think some people just do the "water lock" thing to close their jaw off naturally to try and stop a yawn, and that's how they "discover" they can do it.

6

That's odd, I can do either of those things independently. Maybe it's just wired that way for some people?

Oh thats interesting, i wonder what causes it, the thinking of doing it or actually doing it

Ooh, I can make a little rumble thunder happen if I do that! But why would anyone want to? And weirdly, just yawning doesn't really do it, but squeezing the eyes while yawning does. Huh.

There are several rivers in England called the Derwent.

One of them flows into the Ouse in Yorkshire, another flows into the Trent in Derbyshire, both of which later combine to form the Humber estuary, so the Humber has two Derwents in it

Forza Horizon 4 has an awesome open map based on several disparate areas of England and Scotland pushed together. It includes the Derwent Reservoir and damn, which drains into one of the Rivers Derwent, which leads to Derwent Water - none of which are actually connected in real life. I thought that was a neat Easter Egg.

With decimal you have 10 digits 0-9 and each digit place represents a 10^n*digit, binary is 0-1 digits with each digits place represents 2^n*digit. Binary requires fewer digits to memorize than decimal, but more places to represent the same value compared to decimal. If you are trying to find the most efficient base for balancing the number of digits to memorize vs the number of places a value requires to represent you get a graph like this showing the minimum approaching e (~2.718):

https://www.wolframalpha.com/input/?i=beta%2Flog%28beta%29+from+1.5+to+5

And the derivative approaching e:

https://www.wolframalpha.com/input/?i=derivative+beta%2Flog%28beta%29

That comes into play when you're doing something like picking a base for computer architecture. Almost all computers theses days are binary, but some were base 3 trinary for a bit. But you don't need to pick an integer value and can pick pi or e as a base too. Here's a better write up with an explanation of radix and bases:

That REAL Pi actually ends at 7 digits. Discovered by a greengrocer named Dennis.

There's been an easy say to calculate it since 1800s using an abacus.

Edit: thought the /s was implied with, you know, "Dennis." I knew I should have gone with "Humperdink."

I would like to learn more about this. Wiki says:

In the 5th century AD, Chinese mathematicians approximated π to seven digits, while Indian mathematicians made a five-digit approximation, both using techniques.

So it looks like they were all approximations, but it actually is much longer like I was always taught.

Uh, I mean I could probably write a 30 or 40 page manifesto explaining it, but what it boils down to is the main bottleneck in human society is resource management combined with a lack of vision and purpose.

Anything above the level of the family has resources, needs, and uses that are being managed by people that are ultimately too selfish, too greedy, and not interconnected enough to work together.

Sure, but what do you propose to manage said resources?
