Ooo... that might be an awfully handy part (well, the dev board; I don't have the time/expertise to make something of that quality) for a project/test I want to run. (Last application listed) Off to the pdfs.

(Thanks!)

The demo cards are very precious, I got one yesterday and it required lots of arm twisting, looks good all bases covered. 10uV out for a 10G TIA = 1fA.

When I was trying to guarantee 20fA in 1980 I had test boxes machined out of a solid billet of aluminum (sound familiar).

Awesome. That's one heck of a part. I *definitely* don't have the skills/time/etc to make something like that! I need to do some basic research whether I'd even need that level of sensitivity--fairly confident a simple(r) high-z preamp might do the trick as I'm pumping a goodly amount of energy into the system that should be capacitively coupled to the sense electrodes. TBD. 🙂
 
The universe is barely large enough to accommodate Howard Bloom's ego. The dustcover of The God Problem includes this, accompanied by a picture of the man apparently talking on a cellphone:

"Howard Bloom has been called 'the Darwin, Newton, Einstein, and Freud of the twenty-first century', and 'the next Stephen Hawking'."

There are pages of blurbs, and one searches them looking for any hard scientist. I think he managed to solicit one out of a Nobelist. But the balance are people with curious affiliations with obscure institutions.

Some of Bloom's statements reminded me of Randy California, of the rock group Spirit, who pontificated: "Everything is everything". Wow good acid man!

I was so frustrated by this book, which I purchased and which came highly recommended by a late friend, that I bothered to write an Amazon review. Most of the other reviews were laudatory. Not mine.

The new Ayn Rand mirror encrusted Admiration society?
 
Psycho killer...
My first Bloom was his defense of capitalism, The Genius of the Beast, which I lugged around in the car for a while as a potential read if I were stuck somewhere. But I couldn't finish it. Bloom boasts of saving Prince's career when the latter was about to be put on the shelf. I think a somewhat dubious thing to brag about, although I have listened to some of the stuff from the man formerly known as the man formerly known as Prince, without obvious pain.
 
OTOH John Horton Conway (the inventor of the Game of Life) is impossibly brilliant, and has made incredible contributions to maths.

Today, I just read a 12 year old girl from Essex... from a gypsy community.... was tested to have an IQ higher than Einstein's and Hawkings. For her age the limit was 162. She got 100% and was thus at 162. Phew ! Wonder what her life could be like when she grows up. Impossibly brilliant? Possibly.

It hasn't worked out that well for Marilyn vos Savant, as far as I can tell. IQ allegedly 228.

For a good time, A. E. Van Vogt, Asylum, a longish short story collected in Healy and McComas eds., Famous Science Fiction Stories, Adventures in Time and Space, Random House, Modern Library, 1957. It is also quite seasonal, as it is a vampire story.

The humans are morons, relatively speaking. The vampire Dreeghs are running around 400 or so. The Great Galactics are something else again.
