that's like saying plastics can be recycled quite easily. only in theory - the real effects on the environment are staggering.
> why not just use the electricity directly and not pay the 40-50% penalty of electrolysis? because EV battery disposal can be a huge environmental problem. electrolysis is zero waste.
I've found most western books written on the topic unsatisfying and barely hitting the basics of what's in eastern books. Have found it more effective to improvise one's own techniques using analogies and would…
It goes a bit like this. Most human actions have side effects in addition to their main purpose. Some we are aware of (and may trouble our subconscious), some we are dimly aware of (and brush aside), some we find out…
Progress requires change. Change requires handling tradeoffs between different sections of society with often competing perceptions and interests. Both nuclear power and hydro-electric power have had activist opposition…
From the Indian perspective, one has to flip the question. The question is how did the rest of the world get so advanced ? Unless Indians travel elsewhere they will not find out.
Well it was clear from WW2 records that British were not willing to pay India even for the support India gave to them during the war. They only relented in the face of American pressure. Records also show that much of…
Wealth is not fixed like energy. It can be created. Money can be used to create wealth when it is used to create new products for example. In this case you could argue there were no products in the traditional sense.…
I like the idea of mutating both the output and the key. You are using it for a single pass over the length of the data. You could use the final key as input to another round of crypto. Repeating it for a number of…
No, Indian society does not label children anything other than children at birth. It is a label gratuitously applied by the author, likely as a short-hand to indicate poorer section of society. People from these…
I think Turing's key insight was that a special FA with a tape mechanism could be devised that could imitate any other FA. The power of this FA in imitating other FAs is limited only by the length of the tape. However…
