I have designed a lot of battery chargers for medical and aerospace.
I think it is interesting that we are becoming MORE battery dependent instead of less.
Everyone wants a gas gauge on their battery.
Cell phones kind of have one.
Some flash lights kind of have one.
I interviewed at a gun sight company 9 years ago during the Iraq war. They said one could track the US GIs by the AA batteries on the ground. They never knew how much charge the batteries had or when they would get in a fight, so they compulsively installed new batteries often.
The word 'forum" does not mean "not criticizing books."
"Ad hominem fallacy" is not the same as point by point criticism of books. If you bought the book, and believe it all, it may FEEL like an ad hominem attack, but you might strive to accept other points of view may exist.
Are we a nation of competing ideas, or a nation of forced conformity of thought?
