That's simple - to make quick rotation, you must apply force (torque) and beat inertia - from mathematics could know, the farther from center of mass the more energy will spend to rotate at same speed. So, to rotate faster, you need la

Video have some inaccuracies. As example, said "to detect heartbeat from 100m, 10-20 T", but then talking about "from 100km". So, if carefully looking, SQUID could detect with 10-15T, so need just additional 5 magnitudes

For about price of land and connectivity - in large city land price begin on few millions dollars per square kilometer, and usage of cable channels could cost from 50$ per meter (easy could be 200$/m). Plus, space arrange could last ye

You cannot place dc anywhere, in large cities space is extremely constrained, and land is extremely expensive. Also big problem - connectivity - you cannot place DC where it cannot be connected to power grid and to very powerful network. So

Also, internal CPU caches grow over time - in 286 and before, just was not any cache; in 386 first included page cache for mmu - stores tables with mostly used pages; in next generations sometimes advertised grow of page cache. So yes, even

Sure, we need better math, it is obvious. Unfortunately, nobody at big companies know , what exactly math will win, so competition not end. So, researchers will try one solution, then other solution, etc, until find something perfect, or un
