I joined this Facebook group a few weeks ago and found the admins censor the posts. One such example is below (screenshot). I don’t know what they mean by a “but if text” but I didn’t do anything other than attempt to post two recommended books by Vaclav Smil. I searched for “but if text”

Jennifer Mary Tess This is an opinion article. Here is a paragraph: << Another issue is that wealth limits the perspectives of even the best-intentioned people. This week, Bill Gates argued in an interview with the Financial Times that divesting (ditching stocks) from fossil fuels is a waste of time. It would be better, he

Jerry Savage Said, [the Perseverance rover’s cameras] should all be live.” Well, good luck to you! You’ll be sitting on your butt for the rest of the day waiting for the photos to come onto the screen, pixel by pixel, line by line, until the screen finally fills up. The rover is many tens of

Bill Gates says the richest countries should switch to synthetic beef. 75% of the land used for agriculture is used for livestock. It takes 1750 liters of water for each hamburger. https://www.facebook.com/ScienceNaturePage/videos/257425272515290/?app=fbl
Tesla has negotiated to build a factory in the state of Karnataka in India. I’ve heard opinions about the Indian market for Tesla vehicles and they think that India’s middle class – forget the poor – could afford to buy only tens of thousands of EVs, not enough to justify building a car factory there.

From FB comment In the schematic, find the difference in voltage between the two ends of the resistor. You can find the current through each of the tubes being fed from the unknown resistor by calculating it from the voltage across the tube’s cathode resistor divided by the resistance of the cathode resistor. For instance,

This is interesting. Not a vaccine, it works against the virus that is already in you to stop it from invading cells. So this is a therapeutic medicine. https://www.facebook.com/ScienceNaturePage/videos/1056709391476343/?app=fbl
This was interesting. Jim Gaffigan’s ancestor’s original surname was Gavahan. For some reason that relative changed it to Gaffigan before he left for the US, because the ship’s manifest shows it as Gaffigan. Jim shares a segment of DNA with a distant relative of Derek Jeter, whose mother is caucasian. Transcript is here: https://allarts.org/programs/finding-your-roots/no-irish-need-apply/
IRENA says https://www.irena.org/publications/2016/May/The-True-Cost-of-Fossil-Fuels-Saving-on-the-Externalities-of-Air-Pollution-and-Climate-Change Linked to by a previous article. Quote: << You don’t need to be a genius to read between the lines. When Barrasso says “Undermining America’s energy security will not solve climate change,” he’s actually saying “reducing the use of fossil fuels will not solve climate change.” That’s climate denial. >>
The Tesla businesses are diverse, and compete one against the other. The EV manufacturing business will be restricted by the robotaxi business since fewer EVs will be needed to transport the same number of people. This is disruptive and it’s difficult to tell how much disruption there will be. Similarly, the V2G (vehicle to grid)
