Irreversible process

Recorded by Leon Harvey Chapter 3 Irreversibility So far we have seen that the physical laws essential to the determination of the course of the universe from its present momentary condition are all reversible.

From this it might be concluded that all physical laws must in consequence be reversible, and that therefore there can be no essential difference between the real universe and the reverse universe.

And this much is true, that, provided we examine the motions of the particles of matter, everything that happens in the reverse universe can be described in terms of the physical properties of matter as we know them.

How does the hardware supply chain fundamentally differ from the software supply chain?

The foundational difference comes down to the concept of irreversibility.

Irreversibility.

Yeah.

In the software supply chain, if a zero-day vulnerability is discovered or a malicious backdoor is uncovered by researchers, a vendor can scramble their engineering team, write a patch, and push an over-the-air update on a Tuesday afternoon to fix the problem globally.
