In 1738 the Pope forbid all Catholics from joining a Masonic lodge (open to men of any religion, and secretive, no doubt to avoid Inquisition), and called them 'depraved and perverted' (unlike the Church, of course). No doubt the faithful kept the rumor-mills turning.
Why does the brain need billions of neurons to process 10 bits/s? The stark contrast between these numbers remains unexplained...
Not so much. The stark contrast is the result of a set of stupid premises.
our sensory systems gather data at ∼10^9 bits/s.
Even In the 'machine model' of the brain this article appears to espouse ... vastly simplistic as it is ... the brain processes 10^9 bits of vision, audio, and kinetic clues which usually results in a limited but highly appropriate response ... often in much less than a second ... to gymnastic moves or crossing a busy street, driving a jet, performing on a violin, whatever. That response quickly arrives as the result of a model built on long experience of actual reality.
The authors fail to come up with -any- source (credible or not) for that ridiculous 10 bits/s number. Their model is so simplistic it isn't even worth engaging with.
Everyone in the world is continually exposed to background radiation. That level has gone up considerably since the US began testing atom bombs in the atmosphere. The current AVERAGE level in THE WORLD is about 3 millisieverts per year. In the US it averages about 6 mSv per year (depending on where you live; it might be much higher.)
By comparison, these days:
One chest x-ray delivers 20 μSv = .02 mSv.
On the other hand, one CT scan delivers from 1 to 20 mSv.
One of the early pros working with radioactivity was Marie Curie. She died of aplastic anemia in 1934. Her research notes are still radioactive. Her lab was said to be radioactive as well, yet it was not decontaminated until 1991.
I tried the brick once long ago. 1) No way to verif it works (not just PO's the P.O. 2) That kind of shit may be why so many public POBoxes have been removed. 3) The was of paper (up to 3.5 oz?) -seems- to have worked.
There was when the magazines were struggling to survive. They found they could publish stories for hardcore fans AND for the general public. The success of that tactic meant that a lot of great writers could pay their bills and keep writing ... instead of a few.
I'm so with you on this. Only much moreso. WITF would I EVER want to use stupid little computer where you have to type with your THUMBS? And costs TWICE as much as a great desktop?
"Portability" they say. Hell I went out-of-house to AVOID phonecalls, to live in the material world, not to walk down the street looking in the direction of my toes, missing everything going on around me, talking to invisible people. Pathetic.
How long? Long enough to make a note on it. Then, on slow days, I'll look through the notes and usually go .. nuh-uh ... not enough (... time ... money ... usefulness ...)
