Sacred geometry

My friend told me about this 70+ grand Harmonic Egg and the latest treatment she had done in London. I almost choked when I heard how it's marketed: pure energy-level improvement through vibration, frequencies, and a design that supposedly incorporates the golden ratio and the Fibonacci sequence.

Wowsers. I never knew mathematics could be marketed this way for a beauty/wellness product, but it sort of makes sense. Mathematics often bores people into a deep sleep or meditative state—and boom, (accidentally) achieves the exact "energy improvement" the device claims to deliver.

I'm not here to be a critic of all these fancy new marketing concepts. Storytelling is a great placebo, and I'm a huge believer in the love stories of K-dramas. So, no judgement.

However, it would be fun to elaborate a bit on the wonderful Fibonacci sequence and its applications in real life:

The Fibonacci numbers are a sequence where each successive number is the sum of the two previous ones:

1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, 233, and so on (blablabla forever).

It's a fun lens to apply to human and nature behavior—and scarily enough, it seems baked into a lot of things. Hurricanes spiral in Fibonacci proportions, finger bone lengths (each roughly 1.618× the next smaller one), even some favorite music pieces follow similar patterns.

If you're a trader, Fibonacci retracement won't be alien to you: price movements often correspond with these proportions too.

In layman's terms, take the S&P 500 (the average price of the 500 largest US companies). When it goes up, it doesn't GO UP FOREVER (and vice versa). It climbs a bit, takes a breather, pulls back down, then climbs again.That "breather" (retracement) tends to happen at very specific spots that respect the mathematical relationships in the Fibonacci sequence—like 38.2%, 50%, or 61.8% pullbacks. It's fun to apply these concepts and watch the higher highs and lower lows play out. 

Btw, as of this writing, I am still smirking inside at the pseudo-intellectual way of marketing expensive ASMR.
