ELI5: When humans/animals are born they go from not breathing to breathing with their first gasp of air. Why is this a one way process and why can't we go back to non breathing as in a womb/egg?
Fun Fact: the sensation of "needing to breathe" is you sensing the acidity in your blood rise due to the increased CO2 concentration.
That’s also how the shallow water blackout happens. Because it’s the oxygen that keeps you conscious, but the CO2 that makes you breathe, and they might get out of sync. https://en.wikipedia.org/wiki/Freediving_blackout#Shallow_water_blackout
Oversimplified:
- The period of x mod N, x2 mod N, x3 mod N, x4 mod N, … sequence can reveal the factors of the product of two prime numbers.
- The period is very difficult to find for large numbers.
- Quantum Fourier Transform enables the extraction the period in a fast way. (the only part that quantum mechanics involved and I still can't understand how)
