Posts like this show that not everyone understands what science is, though that doesn’t stop them. Sometimes just having one downvote isn’t enough.

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 ∼1⁢0^9 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.

There was some green and yellow ‘depressionware’ that had uranium, with some slightly radioactive. The kinds of doses involved are in this article;

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.

By calling them names, then getting on with the obvious…

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.

+1 just for mentioning Bukowsky … he is WAY underrepresented on the Internet (which explains why it’s in this state)

Gotta get there earlier … before all those other thoughts get a chance to drown out your perfectly sensible thoughts.

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 …)

If you could retire and have enough to keep you comfortably housed and insured until you’re 90, that’s wealth enough.

I had hated the commercials on local TV (and their insipid local newscasters), and the way Cable networks chopped up films to the point where a 90-minute film took 2-1/2 hours to watch. NOT to mention their 200+ channels with 7 worth watching (for many $$$).

When they shut down analog TV in 2009, that was it for me. I didn’t even grab a ~~free HDTV converter for local stuff. Nothing but Internet ever since. Music? HUNDREDS of online stations.

Big companies become like alien organisms that are embodied in big buildings and employ human beings as blood cells. They are predators that consume human life energies.

Best to do what you think is right … as for Democracy, it’s a good idea, I hope we’ll see it show up one of these days. ‘All men are created equal’ … but then someone’s gotta pick the crops.

The Romans managed to figure out that lead was bad for you. That didn’t stop it from being used for the next 1500 years. Including in gasoline. And in paint.

Up until recently, a lot of US plumbers used lead pipes in homes to bring drinking water to the faucet. Even if home lead plumbing is replaced, the pipes leading to the water meter may be lead.
