I just learned the mind palace technique to memorize stuff and wanna put it to use.
Do you remember the Fibonacci sequence? You can use it to convert miles to kilometers .
2 mi ~= 3km
5mi ~= 8km
8mi ~= 13km
13mi ~= 21km
And so on.
That’s brilliant.
That’s awesome thanks !
Simple recipe formulas that are scalable
Learn some alphabets of foreign languages. Russian is fun because some of the characters looks like English letters but have completely different sounds. Korean is also cool because it looks crazy complex but it’s actually extremely simple.
I don’t know any Korean, but the Korean alphabet is by far the best writing system I’ve seen.
The characters make the shape your mouth makes while annunciating that letter. It’s ingenious.
A crowd pleasing karaoke song!
I’ve never seen these flop at kareoke (if done with average competency):
Jump around - cypress hill gang
I will survive - Gloria Gaynor
Bohemian Rhapsody - Queen
Billy Jean - Michael Jackson (many other covers)
Shake it off - Taylor Swift
Pick 1 of the above plus a Beatles song and you’re good for impromptu Kareoke.
If you have a few days notice and a friend to plan with the options expand…
I’ve got Sir Mixalot’s “I like big butts” on lock
New Jersey state law requires everyone to sing along to Don’t Stop Believing.
Converting Celsius to Fahrenheit:
- multiply by 2
- remove 10%
- add 32
This is wrong? Taking 20°C as an example. Following this formula gives 48°F when it should be 68. Could you perhaps be supposed to add 32 instead of 12?
Yeah, it’s supposed to be c * 2 + 30
Nothing can go faster than the speed of light, not even fahrenheit temperature units.
For day-to-day purposes, if you are used to Fahrenheit but not Celsius or vice versa, and all you want to do is get a rough sense of how warm or cold it is outside without having to do arithmetic involving fractions in your head, then remember that there are two temperatures in Celsius that are roughly the same in Fahrenheit but with their digits transposed: 16° C ~ 61° F, and 28° C ~ 82° F. You can then roughly interpolate/extrapolate by about 2° F for every 1° C.
Also freezing is 0 in Celsius, so 32f is 0c. That one always helps me. Not as useful for converting c to f.
Bob and Doug Mackenzie thought me to roughly convert C to F by taking the temperature in Celsius, doubling it and then adding 30. It gets you in the ballpark.
A completely random ordering of a deck of cards. You can have a deck pre-stacked in this order, learn some false shuffles, have someone pick a card and place it back anywhere they want without marking its location in any way, and when you inspect the deck you know exactly what their card is. And they’ll never guess that the way you did it was memorizing the order of every card in the deck.
I’m sure there are a lot more advanced ways to take advantage of this, just a handy ability to have in your back pocket (literally).
If you’re going to memorise a deck of cards, you’re better off learning something like the Mnemonica Stack as you can use it as the basis for a whole load of card tricks.
