Happy Pythagorean Theorem Day!

10² + 24² = 26²
This is the last one we’ll experience in our lifetime.

This is the Weierstrass function, a “monster” that is continuous everywhere but differentiable nowhere. First published in 1872, it prompted scrutiny of assumptions in calculus. Similar functions are used to study random motion and analyze risk. quantamagazine.org/the-jagge…

An Arctic Fox in the process of changing from her summer coat to a winter one.
The fur of the Arctic fox provides the best insulation of any mammal and its thickness increases by 140% during winter.

🚨wtf. OpenAI says its new internal model it began training just 24 days ago has already resolved more than 100 long-standing open problems across most areas of mathematics.
The pace has surprised even OpenAI's own mathematicians.
An independent group including Edward Witten, Timothy Gowers and Martin Hairer is now helping assess the results and coordinate how they are released.
We’re working with an independent advisory group of mathematicians to help OpenAI responsibly share advances in AI and mathematics.
The group will advise on how we assess and communicate new mathematical results, uphold academic and professional standards, and build tools that support mathematical research and learning.
Through this work, we want mathematicians to be at the center of shaping how AI supports mathematical understanding and how its benefits reach the wider community.

I’m very confident this yr’s El Nino will be the strongest in the entire instrumental record (1850-present), even besting historic events like 1877-78
This will probably be the strongest El Nino in at least ~250 yrs, or since the Great El Nino of 1789-93

Aug update from ECMWF predictive ensemble is genuinely extraordinary from extreme #ElNiño perspective. One implication: it is now indicating not only 70-100% odds of above avg winter precip California-wide, but also 70-100% odds of DJF 26-27 being among the top 20% of wettest CA winters (!).

This is real footage from 120 years ago.
None of the people in it knew that the city around them had four days left...
What you are watching is a cable car gliding down Market Street in San Francisco, filmed on the 14th of April, 1906.
The camera was mounted on the front of the car, so you see the city exactly as it was: the crowds, the horse-drawn carriages, the early automobiles weaving through traffic, the men in hats, the great buildings rising on either side. An ordinary spring afternoon in a thriving American city.
Four days later, on the morning of the 18th of April, a magnitude 7.9 earthquake struck. The shaking lasted under a minute, but it ignited fires that burned through the city for days...
By the time it was over, more than 3,000 people were dead and roughly 80 percent of San Francisco had been destroyed. Almost every building you see in this footage was gone.
And the film itself nearly went with it.
The negative was placed on a train bound for New York on the 17th of April, the day before the earthquake. Had it left a single day later, it would have burned in the fire along with the studio that made it.
This entire moving record of a lost city survives because of one day...

Right in the middle of a rainy moment, a tiny bird becomes the star of something truly magical—a perfect water droplet lands on its head, forming a crown-like splash that feels almost unreal. The timing is flawless, capturing a split second where nature turns playful.

California this wet season:
- Wettest Oct–Dec on record in Santa Barbara, Ventura & parts of LA County
- Driest & warmest March in state history
- 115" February snowstorm + deadly avalanche near Donner Summit
- 2nd-lowest spring snowpack on record
- Northern Sierra on track for a top-5 wettest April on record
- Latest start to ski season ever in parts of the Sierra
- 21 straight days of tule fog in the Central Valley
- Christmas Day tornado in LA County
- 7.5 inches of snow in an hour on Christmas Eve in Mammoth
- 40 million people under a flood watch in late December

Zone 1 is an investment.
It builds your fat-burning engine and expands your energy reserves.
Zone 3/4 is a withdrawal.
It spends from that reserve.
Want your hard training to actually work?
Build the reserve first.

The 'Beirut Explosion' of August 4, 2020, is considered one of the most powerful artificial non-nuclear explosions in history.
It was equivalent to around 1.1 kilotons of TNT and generated an M3.3 earthquake.

🚨🇺🇸 Artemis II just sent back footage of the Moon so close and detailed you can see every crater and ridge like you're flying over it.
Humans are orbiting the Moon again for the first time in over 50 years and the view is absolutely unreal.

This footage was not taken from space during the Artemis II mission.
It was created by a photographer named Adam Kyle Jackson, from earth, who recently posted it on Instagram:

Spearmint and caraway seeds smell completely different.
Fresh. Sweet. Minty vs warm, spicy, earthy.
Yet the difference comes down to mirror images of the same molecule: Carvone.
Same atoms.
Same bonds.
Same formula.
Only one thing changes: 3D orientation.
• (R)-carvone → spearmint
• (S)-carvone → caraway
Our noses can tell them apart because olfactory receptors are chiral too they “feel” molecular handedness, just like a left hand doesn’t fit a right glove.
This is a beautiful reminder that in chemistry (and biology), shape matters as much as composition.
Something you can literally smell.
Chemistry is everywhere - even in your spice rack.
