From 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.

FFP EP. 3 | Oldest Molecule, Programmable Proteins, Europa Radar & Light’s Double Life

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.

In this episode

The “oldest molecule” puzzle (HeH⁺), cooling the early universe, and why JWST’s findings matter
Programmable proteins: reassigning codons, recoding organisms, and real biosafety
Europa Clipper’s REASON radar test at Mars: frequencies, ice thickness & ocean clues
Double-slit, demystified: single photons, “which-path” info, and measurement reality
