Are there any other old-farts in here who are thinking "S-100 Bus"??? Everything was run from the backplane. Want a new CPU? Plug one in!

At first glance, this approach appears to re-invent an applied mathematics approach to optimal control. There, one writes a generalized Hamiltonian, from which forward and backward-in-time paths can be iterated. The Pontryagin maximum (or m

When I was in grad school back in the '80s, 9 track magtapes were the standard for lots of things: backups and long term storage being some of them. (I still have one or two tapes in a box somewhere.) About 10-15 years ago, it dawned o

As the Dad of a preemie, our only child who died at age 25, my heart goes out to the Nadella family. It would not surprise me in the least if Nadella steps down as CEO sooner rather than later. The trauma is that large.

True. But, until the practice became the mainstay of new shale gas production hydraulic fracturing was about as uncontroversial as drilling itself. (Yes, there are deliberate ironies in that statement.) Geologically speaking (roughly), a ga

by fghorow 5y ago
Regarding "repurposing". You have it backwards. Hydraulic fracturing for geothermal -- then known as Hot Dry Rock, but now called EGS -- has been around in practice since (at least) the 1970s [1]. It's basically the creation

Very cool! Gives great intuition for geometric spreading on the surface of a sphere! Modulo phase velocity and attenuation, it makes clear that the amplitude/energy density could actually increase past the great circle!

For western US trained geoscientists, the Bishop Tuff [1] (from the ~750,000 years ago eruption of the Long Valley Caldera, near Mammoth Mtn. in California) is a "modern" comparable ashfall deposit. This was quite a bit larger (ed

OK, Another reference is [1], that agrees with the result given by the OP. I'm not trying to do research here, I'm just boggling at the unintuitive result, and trying to see if there might be a flaw in the chain of logic. The fact

Is there some obvious way (that I seem to be missing) to see that the centrally inscribed D-sphere must touch all of the other spheres in high dimensions? That's probably a stupid question, but while that fact is intuitively obvious

FWIW, NGC-1052-DF2 has it's own Wikipedia page, that discusses (and more importantly cites some literature about) the relation between it and MOND. https://en.wikipedia.org/wiki/NGC_1052-DF2

Let me preface this by saying that I am by NO means an expert in any of this. My thought process was simply along the lines of: 1) If MOND is true, it should be evident in the rotational structure of every galaxy observed. 2) Here is a gala

by fghorow 5y ago
Yeah, well. That is an observation that is pretty bloody difficult to explain with MOND type theories. Any MOND proponents want to have a try?

When I lived in Perth about a decade ago, I had a DSL line from an exchange about 3-ish km away. If I remember correctly, I got 512kbps down, and 56k modem speeds up. This was not outer-whoop-whoop either. Metro Perth. Telstra. Ya gotta lov

Wet string? OK, fine. But I defy ADSL to work over something really challenging. Like Telstra copper in Australia.

And where exactly does the energy stored in a battery come from, do you imagine? This is PV powered production of hydrogen. Yes, the PV electricity could go directly to a battery, granted. But the PV cell is only about 20% efficient in th
