The prehistoric Einstein would not have access to pen or paper. Or mathematics (beyond simple counting). Or complex language to describe new concepts. There is a reason why both Leibniz and Newton came to calculus at around the same time -

Exactly - a decade is a long time; you can be a youth of just 60 years old and make locker room comments about women and furniture shopping that are captured on a hot mike! People should realise that we mature when we reach 70 and change ou

Fair point. A minor detail is that he mistypes the standard term : > I used “Euler path” instead of “Eulerean path” just to be consistent with the referenced book [1] definition Should be 'Eulerian'. It's not horribly conf

edit: Never mind - I hadn't read far enough in. He means 'Eulerian graph', I think. As in a graph with an Eularian trail. You know it might be nice for people to get the terminology right if you are writing about this stuff..

> the proteins we see today may in some sense be formed out of primordial peptides. This seems reasonable, but another possibility is that modern proteins (domains) are 'carved' from larger proteins that had a looser structure.

Although it doesn't alter the analogy much, there is also the even higher level of 'quinary structure' - although it is disputed: https://www.ncbi.nlm.nih.gov/pubmed/23943406

As for a 'British' accent, there is huge diversity within the UK. Cornish, Northern Irish, Yorkshire, Aberdonian, etc. It used to be even more pronounced, with neighbouring villages in England having distinct accents. Nowadays, i

However, all the life we know of is part of the same Earth system. Just because some extremophile exists in a freezing desert or boiling pool does not necessarily mean that the same environments on other planets would have those organisms

Another problem is breaking/remaking these metal bones. Biomineral structures can be reformed - bones break mechanically, and have to be repaired. While biomineralization is mentioned, I'm not sure how easy it would be to 'di

I'm not sure if you could work out from a genome what the cell should look like - probably not. An important point is that cells are always born of other cells. In other words, a cell replicates by dividing itself, building the parts a

we don't ask them to actually provide their tests, but implementing a non-trivial algorithm without tests is optimistic at best. we give them a couple of examples (input, output) pairs - surely you would at least run your implementatio
