Recently discovered this curious formula for converting miles to kilometers that uses every non-zero digit in base ten exactly once. I hope you all find it aesthetically pleasing! :) #MathSky #MathsSky #Mathematics #MathChat #MathsChat
![Using every non-zero digit exactly once:
5⁶ miles = (318 × 79 + 24) kilometers
Proof:
5⁶ miles = 15625 miles
× 5280 ft/mile
× 12 in/ft
× 2.54 cm/in
× 1 m/(100 cm)
× 1 kilometer/(1000 m)
= 25146 kilometers = (318 × 79 + 24) kilometers
Footnote:
The reason 1 inch is exactly 2.54 cm is due to the International Yard & Pound Agreement signed during 1959 which standardized the yard [3 feet] as 0.9144 meters.](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:vhljf2q5ywln4sflbma4x2cs/bafkreifwgrcwvbkeu2q7iaeuqtnkxvoooiam47amlhgnsozprxt4g2w3rm)

Would you rather memorize ten formulas or just three?
Also, keep in mind that this is just for the basics of kinematics and there are even more physics topics with their own sets of formulas!

![Red Title: "Dear Students, this is why we learn algebra!"
On the left-hand side, we see the minimum of TEN kinematics formulas you'd have to memorize if you cannot rearrange equations. On the right-hand side, we see the 3 usually memorized kinematics formulas [along with a clarification that the last one can technically be derived from the previous two by solving for time in the second then substituting into the first and simplifying]. Uniform acceleration is assumed in both cases.](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:vhljf2q5ywln4sflbma4x2cs/bafkreift3jquotzl2s42iwm4bdrm7jvr7albfhpdqmp46fv66blrwncsj4)

Agree or disagree?
The history of mathematics should be a part of the curriculum at KS4/5. One valid criticism of British education is that pupils specialise too early. Exploring the history of maths could provide much-needed cultural breadth.

Teaching myself maths since my 1st suicide attempt was literally coz of failing in maths class, starting with '''easy''' year 7 stuff. Why is the first unit almost all unknown things 😭😭
I'm mathematically illiterate but maybe in like 12 years I'll be Average 😁😁

Take the binary representation of 1/√2, but then interpret the digits (still all 1s and 0s) in base-3. Clearly this number is also irrational. But is it expressible in some kind of closed form?

I'm working on a new talk about big prime numbers - how we choose which numbers to check, primality tests, and what we use big primes for. Anyone got topics or factoids they'd definitely want to see as part of that talk?
(Also, please boost this so that I can find MathsSky, which surely must exist)
