Stay ConnectedFrom First Principles is a fast, funny, and rigorous breakdown of the biggest science stories of the week, hosted by Lester Nare and physicist Krishna Choudhary, PhD. We go past headlines into the actual mechanics: what happened, why it matters, and what everyone’s missing.
Expect physics, space, AI, energy, biotech, and the occasional “wait… is that real?” story. If you’re curious, skeptical, and you like learning in public — you’re in the right place.

Interstellar visitor #3 is here. We unpack 3I ATLAS (why it’s moving so fast, why we finally saw a tail, and how Hubble/JWST—and maybe even Juno—could nail down its makeup). Then we dive into the Vera Rubin Observatory, the 32-gigapixel camera that will turn the entire sky into a time-lapse movie and supercharge discovery. Next: AI just boosted CRISPR by predicting and guiding DNA repair (Pythia), making edits cleaner—especially in non-dividing neurons. And we close with a crossover of dinos + particle physics: preserved T. rex blood vessels revealed by a synchrotron. Mystery Box: the viral “Black aliens” meme.
We go from the universe’s first chemistry to tomorrow’s designer biology, swing by Mars to tune Europa Clipper’s ice radar, and finish with a fresh take on the double-slit experiment.

Last week the Earth finished a full rotation one millisecond early – but that’s just the opener.
In this week’s From First Principles we dive into six mind-bending headlines with our trademark mix of hard science and light-hearted banter:
Earth’s fastest spin ever recorded – what shaved a millisecond off the day and why your chakras are still safe.
ALMA spots a “baby Earth” forming 1,300 light years away – the first direct look at rocky planets in the making.
Biggest black-hole merger on record – 15 ☉ of mass vaporized into pure gravitational waves, detected by LIGO/Virgo/KAGRA.
CRISPR reveals a vitamin-D “kill switch” for tumors – how silencing one gene in pancreatic & colon cancers triggers 4,000 downstream changes.
A star that died… then died again – the first confirmed “double-detonation” white-dwarf supernova.
DeepMind’s Aeneas AI deciphers broken Latin tablets – giving historians new text, provenance and dating in seconds.
