Me too! I've been reading things for radio broadcast, but I have no idea what I'm saying... Concentrating too hard on reading ahead of what I'm speaking so I can do the intonation right...
Even with mass-energy equivalency, it is much easier to change mass into energy than the other way around. But as far as changing an object's *weight* by pressing a button, that should be possible. Weight is dependent on both on the mass and distance separating two (or more) objects, or the acceleration of an object. If pressing the button initiates something to accelerate that object away from another object then its weight will change...
(Note: Pedantic me has not yet watched Eureka, so I don't know how this weight-changing object is used)

Alexandre Olivanah, it was entirely fictional AFAIK. Eureka was the fictional city of genius inventors in the series. no amount of internal motors could enable a ball to dynamically change its weight. though mass is energy, in day-to-day life you can most often assume it's conserved, which is why I found it so creative and amusing
♲ @mbeisen@twitter.com: because of vaccine mandates we’re losing teachers who don’t believe in science, healthcare workers who don’t believe in medicine, and police who don’t believe in public safety…
Reminds me of a riddle I heard in high school (around the time Canada switched to metric): If it's 0 Celsius here, and twice as cold in Ottawa, what's the temperature there?
Conflating both the #ZeroIsNotMinimum problem and a negatively worded question about positive values.
Think of "If it's 273 Kelvin here, and twice as cold in Ottawa"... would that be 546 Kelvin in Ottawa, or 136.5 Kelvin?
Hang in there, Dr. Sekula. Your summer somewhat mirrors mine: Conflicted about working in a Covid environment; trying to stay engaged in politics (not physics research); the loss of my father and admitting my mom to a long-term care facility where Covid mortality is high. We'll pull through, and if the future looks different from the past that's probably a good thing.
But human labour only produces surplus value when it's being exploited. If humans are paid a fair value for their labour then there is no "surplus", ie. no profit for the corporate owners. This is why I favour worker-owned co-operatives instead of capitalist-owned corporations.
I think the #blockwars folks may have indirectly caused this. There are people who file complaints against client apps that don’t build in blocklists against specific servers whose moderation policies they dislike.
I think that #Matrix / #Element competes with one or more Google-owned chat-type services. Since they gatekeep the overwhelming majority of Android users’ software installation, a good antitrust lawyer would be helpful. I’ll bet that faxing a bunch of documents to #USDOJ and various states would suddenly cause Google to decide that Element doesn’t violate their policies anyway.
(Someone said it was “Boomers at Google that don’t understand federation”, but first of all, I’m certain that most GOOG employees are far younger than you and I, and secondly, I’m sure someone at Google understands federation, though they obviously dislike not being in control. Google Talk was federated with #XMPP, while Google Plus was basically #Diaspora with federation stripped out.)
