So I have been pretty good at PowerPoint my whole analyst life, but I hung up my powerpoint boots in Dec 2025 when AI showed it was far better.
Now I am a Director as execution is left to @claudeai and @Copilot but sometimes it tells lies like this ...
Hi Hamid,
I am Yusuf. I came across your mountains post from yesterday 25/4, and it stopped me completely. I decided to push myself to the limit and implement your formula from scratch, pixel by pixel, as a personal mathematical challenge.
After careful study of the image, I have successfully identified and understood 12 of the 14 mathematical objects:
✓ F(x) — color compression to [0, 255]
✓ N_s(x,y) — fractal noise with 6^5 * 5^(-s) frequency scaling
✓ E(x,y) — fractal envelope as a 50-term weighted sum
✓ Z_s(x,y) — layer occlusion product
✓ S(x,y) — sky value
✓ R(x,y) — layer depth value
✓ T(x,y) — distance to mountain center
✓ B(x,y) — slope angle via arctan
✓ A(x,y) — layer brightness
✓ H_v(x,y) — final color channel for v = 0, 1, 2
✓ Coordinate mapping: x = (m-1000)/600, y = (601-n)/600
✓ The full N_s structure
The two I cannot read precisely enough from the image are:
✗ J_s(x,y) — the mountain shape indicator
✗ K_v(x,y) — the lighting kernel
I can see the general structure of both. J_s uses a double exponential with cosine products and E(x,y)/1000 in the exponent, and K_v sums 50 terms of (91/100)^s weighted by cosines involving T, B and v. But the exact coefficients inside the ridge shape term of J_s and the cosine arguments of K_v are too dense to read at the resolution I have.
What I am currently seeing in my attempts: the layering and occlusion work correctly and the fractal texture E renders as expected, but without the exact J_s the mountain silhouettes are wrong. Peaks appear at incorrect positions and the snow and rock boundary does not match your image.
This is purely a personal challenge. I am not doing this for any commercial purpose.
Could you point me to where the full formula is published, or share a higher resolution crop of the equation panel from that post? Even just confirming those two functions would be enough to complete the implementation.
Thank you.
Yusuf
I was always fascinated about Temu's disruption of the ecommerce space. As an experienced supply chain professional with grounding in Brick and Mortar retail supply chain management and subsequent ecommerce startup supply chain management experience, I was mesmerized by Temu's
How a Chinese app called Temu just rewrote the rules of global e-commerce (and made Nigerian giants sweat)

Picture this: November 2024, Nigerian e-commerce is cruising along nicely. Jumia is king, Konga holding steady. Then Temu shows up like that friend who crashes..
