Researchers have recorded the briefest interval of time ever measured: 247 zeptoseconds—the duration for a photon of light to traverse a hydrogen molecule. That's 0.000000000000000000247 seconds.A zeptosecond equals one trillionth of a billionth of a second, a realm where

New paper! How do matter and electromagnetic fields interact with curved spacetimes in general relativity? For a long time, there have been two basic models: GR kinetics, and GRMHD. Neither entirely satisfactory. In this paper, we show a third way. arXiv link below... (1/10)

In the 1960s, Stanislaw Ulam, while doodling during a boring presentation, discovered a surprising pattern when he arranged numbers in a spiral and highlighted the primes. This spiral revealed a striking pattern and structure in the distribution of prime numbers. đŸ“·visualizing

A new technique called ‘mind captioning’ generates descriptive sentences of what a person is seeing or picturing in their mind using a read-out of their brain activity, with impressive accuracy. go.nature.com/4nZaZId

Our mathematical universe. Fractals. Reminds me of an inside-out Mandelbrot set, with delicate filigree that reveals a zoo of intricate and infinite structures. A meditation on ((Csin(Z) * ((Ccos(C)-P1)/C)) + (Ccos(Z) * (Csin(C)/C)))/P2. By gdsentropy, used with permission.

Area-minimizing surfaces are an important mathematical tool, so long as mathematicians can guarantee that singularities are rare, and can be wiggled away when they do appear. For decades, no one could prove this beyond dimension 8. Now that’s finally changed.

The hunt for a quantum spin liquid has involved many different material families and models. Now, Zn-barlowite has been found to have similar behaviour to another candidate material, herbertsmithite, hinting there may be universal physical behaviour. nature.com/articles/s4156

Did you know? An explosion of zinc fireworks occurs when a human egg is activated by a sperm enzyme, and the size of these “sparks” is a direct measure of its ability to develop into an embryo. In other words, life begins with a flash of light.
