Dogs are important. I'm old, and I have two. Wagging tails & licks when I come home are really important, a claim I make comfortably without objective evidence.

Fair point, and one of particular interest to me, age 76. I find my short-term memory is in decline, magnitude depending on specific circumstances. This annoys me, and to a lesser degree, my wife as well. Really, where did I put that damned

Amateur here, certainly. But I recall that one of the two consequences of Bell's inequality (shown to be valid AFAIK) is that there isn't an "objective reality". Kind of like nature makes it up depending on what the obse

This topic is a great example of how results from down-in-the-weeds biochemistry immediately raise questions at the top levels of consciousness and existence. “Leaning into discomfort” for personal change may well work for much more than a

If you're wired like Marcus Aurelius, maybe it'll work out ok. Peoples' neurochemistry differs enormously. One person's positive reinforcing experience is another's nociceptive hell. (source: Ph.D. neurophysiologist

DLC (diamond-like carbon) generally lacks long-range crystalline order. It's thermal conductivity is quite low.

No need to poke somebody. Just turning it on would cause it to ramp up until air breakdown at the output electrodes, where you'd have a 50mA plasma!

There are amplifiers that increase the suck. One is physician ownership of diagnostic clinic(s). A strong tendency to order tests can be remarkably enriching, way more than a paltry $500K.

Every time I consider LASIK or other procedures that would remove my need for glasses, I recall that in 23 years, my obligate glasses have saved each eye once. Two dead center strikes from disintegrating server cooling fan blades. I'd

Cool results and methods, but I'll disagree with one of the article's statements. In talking about the work done on e. coli, a non spherical cell, it says the methods had to be changed due to "turbulence" attendant to th

Fiber-reinforced composites are basically analogous to spaghetti dispersed in glue. Really strong in tension, when the (in this case, carbon) fibers are taking nearly all of the load. In compression, the fibers have nearly zero resistance t

I'm building a CVD system to make arbitrarily large single crystal optical quality diamonds. Not a coder, so I'm using ChatGPT and Claude to show me how to integrate microwave power sources, vacuum & gas supply systems, and ot

Lab-grown diamonds can be tailored to exhibit the same impurities internal stresses, etc. that cause a minority of natural diamonds to fluoresce. This has not been a goal to date for synthetics because the highest price point is for diamond

Two points just FYI in thinking about the sudden shift to synthetic diamonds from natural stones: • Scale: I'm aware of one company that operates over 700 CVD systems that each make 25 stones/run - there are at least 3 others of s

I'm working on making diamond single crystal rods as long as you like. For lasers and the like.

Didn't know about the use for meat curing. I've routinely bought KNO3 for stump removal.

Opposite to my view. If there's no pre-ordained purpose, we're free to invent our own. I find that very freeing and hopeful. And a lifetime project.

I started on Zepbound March 1. The food noise is gone. I'm no longer distracted by intrusive thoughts around food/hunger, which after a lifetime of enduring such, is wonderful. The strongest behavioral effect is that I no longer s

This scan should preclude forgery of the work. I doubt there's a way to duplicate the crack patterns that anyone can now refer to.

There are more egregious cases, of course. https://www.nytimes.com/2025/04/25/us/politics/us-citizen-de... A post elsewhere about the details said ICE found the two-year old was unable to 'desc

Our legal system has always depended on vibes to mitigate technically correct unjust or catastrophic outcomes. It's broadly labelled "prosecutorial discretion", and operates at every level of the justice system. IMHO, it&#x27

I think this post isn't limited to OSINT. It's widely applicable, probably where AI is being adopted as a new set of tools.

This isn't measurement of albedo changes. It's measurements of spectra that exhibit Doppler effect, which permits measurement of wind velocity. From the abstract: "We studied the transmission spectrum of the hot Jupiter WASP-

It takes just as much ∆V to throw a rock from the Oort cloud to Earth as to throw the same rock from Earth to the Oort cloud. The aliens don't get an energy advantage by holding the high ground.

Even at a remove of decades from when I worked at JPL, this makes me very sad.

The scientist M. Temple Grandin is known for her great contributions in the field of mitigating pre-slaughter animal panic. She is autistic. Her methodology included walking the chutes used to direct cattle to slaughter and working out in g

Probably heat due to gravitational crustal deformation (in multi body systems) and/or radioactivity of planetary constituent elements.
