Your body hydrolyzes ~10²⁶ ATP molecules daily— (≈ recycling your body mass in ATP ~1000 times). At 55 kJ/mol under cellular conditions (vs 30.5 kJ/mol standard), this molecular currency runs on a 25 kJ premium. Kleiber's law shows metabolic rate scales as M^0.75, not M.

We've updated our LaTeX Editor layout!

We've replaced the multiple frames for the table of contents, build log, and error log with a new, unified single-frame viewer.

Take a look at the new version (left) compared to the old one (right).

Bond energy across 17 molecules fits the universal Morse potential model: E(r) = D_e[1 - e^{-a(r - r_e)}]^2. Computed in R, results confirm quantum predictions:
• Shorter bonds = stronger bonds
• Bond order boosts stability

Yes, I'm not referring to accessibility in the formal sense. We created CoCalc's AI Assistant primarily to assist people in coding with Jupyter; it is largely a byproduct of that integration. We just happen to support LaTeX. It can be more efficient to generate templates because you can tailor them.
