#PiezaDelDía 🔸 Xiuhcóatl
Ornamento de oro laminado con la imagen de Xiuhcóatl o serpiente de fuego, arma representativa del dios de la guerra Huitzilopochtli, la que, según el mito, usó para derrotar a su hermana Coyolxauhqui, consolidando así su poder como deidad solar.

"The differences between modern human & Neanderthal brains, as estimated from endocranial reconstructions, do not meaningfully exceed those among different modern human populations. The implied average cognitive differences are extremely small, with extensive population overlap."

String Theory Lecture 2
In Conformal Gauge, the String Becomes a Wave Equation
Episode 1 showed the geometric jump
point particle -> worldline
string -> worldsheet
Episode 2 is the dynamical jump.
The Nambu-Goto action measures the area of the worldsheet,
S = −T ∫ dτ dσ √[−det hₐᵦ]
but the square-root determinant is awkward to work with. So we usually rewrite the same classical theory in Polyakov form,
S = −(T/2) ∫ dτ dσ √[−γ] γᵃᵇ ∂ₐXᵘ ∂ᵦXᵤ
Here Xᵘ(τ,σ) tells us where each point of the string’s worldsheet sits in spacetime, and γₐᵦ is the metric we put on the worldsheet.
The power of this form is that we can choose a convenient gauge. In conformal gauge, the equations of motion simplify to
(∂²/∂τ² − ∂²/∂σ²) Xᵘ = 0
So the string’s spacetime coordinates behave like waves living on the worldsheet.
The τ-derivative measures how the string changes in worldsheet time.
The σ-derivative measures how it bends along its own length.
For a closed string, σ is periodic
Xᵘ(τ, σ + 2π) = Xᵘ(τ,σ)
and the wave equation splits into two traveling pieces,
Xᵘ(τ,σ) = Fᵘ(τ + σ) + Gᵘ(τ − σ)
One family moves one way around the string and the other moves the opposite way. These are the left-moving and right-moving modes.
In the render, the bright loop is the string at the present moment. The glowing cylinder behind it is the worldsheet it has swept out. The cyan curves trace one traveling family, and the gold curves trace the other. They are the visual version of τ + σ and τ − σ.
Therefore, the theory has an internal wave equation, and its normal modes are the raw material for the string spectrum.

Consider this argument: Is it possible to grasp the quintessence of consciousness by subtracting every sensory modality and still remain in a state of conscious experience? The answer is no, because eliminating the interoceptive substrate of consciousness would result in death.
Jesus Ramirez-Bermudez@JRBneuropsiq
This is a fantastic conversation. Dr Seth makes a great argument against computational functionalism, by highlighting the biological underpinnings of #consciousness: metabolic constraints, interoceptive inputs, multiscale processing...

Your brain does not age evenly. Decline starts in frontoparietal networks that run decision-making and strategy.
Creative expertise alters that.
A @NatureComms study using EEG-based brain clocks shows experts in music, dance, visual art, and gaming have lower brain age gaps. Their brains register younger than their actual age.
The mechanism is efficiency.
Creative work increases local efficiency in specialized circuits and strengthens global coupling across networks. Less energy, faster processing, tighter coordination.
This effect scales with expertise. Years of high-level creative demand reinforce the exact regions most vulnerable to aging.
Creativity is not expression.
It is neural preservation.

The philosopher in question:
"You see, the question everyone asks me, ‘Slavoj, can machines be conscious?’ is already the wrong question, the ideological trap! Consciousness is not some nice software upgrade you install after enough training data. Consciousness is the symptom of a fundamental failure. It is the crack in the symbolic order, the traumatic Real that refuses to be reduced to code. An AI that ‘wakes up’ and says ‘Cogito ergo sum’ would be like a perfectly functioning toilet suddenly starting to write poetry about its own excrement (technically impressive, but deeply perverse). We don’t need machines that think, we already have billions of humans who think they think while actually repeating the same ideological script."

Make no mistake, the pro-data center lobby is hard at work! Don't get fooled by their nonsense, AI is not a revolutionary or transformative technology. At best it offers marginal gains in productivity, but its harms outweigh its benefits. The data center buildout is not justified
Cato Institute@CatoInstitute
Banning data centers is like banning railroads at the start of the industrial age, say Cato’s @jrhuddles and Christopher Gardner. Instead of blocking AI infrastructure, states should consider forward-looking policies, so innovation and consumers both have the infrastructure and energy resources they need. ow.ly/ja0550YFGHA
