Lifting Mt. Everest
Do I have this correct?
1 joule can lift ~102 grams 1 meter against Earth's gravity
Let's call 102 g an EMU
Given e = mc², 1 kg of rest mass represents ~10¹⁷ J of energy
Mt. Everest's mass is estimated to be ~1.75 × 10¹⁴ kg = 1.75 × 10¹⁷ g = 1.75 × 10¹⁷ ÷ 102 g = ~1.7157 × 10¹⁵ EMU
therefore,
Applying 10¹⁷ joules to lifting ~1.7157 × 10¹⁵ EMU means Mt. Everest could be lifted 10¹⁷ ÷ 1.7157 × 10¹⁵ = 58 metres with the energy of 1 kg rest mass
Astronomers sure do conjure up a lot of spooky images when they look out into deep space. A short Halloween thread:
Let's start with the Cosmic Bat Nebula (LDN 43).

A research group looked at results for over 97,000,000 people, and found
COVID-19 was associated with a 49% increased risk of new-onset autoimmune-related diseases
and flat out:
SARS-CoV-2 infection increases the risk of autoimmune diseases, particularly those affecting vascular and connective tissue. Risk is amplified by severe infection and attenuated by vaccination
and it's hard to imagine a stronger proof - most countries don't have 97 million people in them!

Glad UC Riverside still has a scientific glassblower. Fewer and fewer US campuses do.

Dogs In Chornobyl are Mysterio...
Great white sharks are perhaps the most feared predators in the ocean. But what might they fear? Probably orcas. In the Gulf of California, the killer whales have been spotted hunting young great whites by flipping them over before eating their energy-filled liver. Blech. It’s wild out there. @CBSNews has the story:
Three Chinese astronauts who have been living on China's Tiangong space station since April 24 were set to return to Earth Wednesday when a piece of suspected “space junk” struck their return capsule — just hours ahead of departure. Looks like they’re going to be there for a while. Read more from @LiveScience:
1) Why do you love plants and how do you interact with plants in your life (intentionally/background)?
2) What makes learning about plants/ecology accessible/inaccessible to you (ie compare with birding)?
3) Do you prefer a formal or informal teaching environment, and why?
4) What are some subtopics relating to native plants that are of interest to you?
5) Would you prefer to learn to ID plants with or without phone apps?
6) How many plants would you be comfortable learning to ID in a 1 hour session?

Rotational symmetry in physics.
- from Guido Tonelli's 'Genesis: the Story of How Everything Began'
Robots are cool and all, but have you tried shooting squishy humans into space so that they can use their eyeballs to appreciate the features on the surface of the Moon with more nuance??
Next time you catch yourself saying: 'Fuck. That was stupid. Why did I do that?'
--- rewrite it: ---
'Fuck. That was thoughtless. Why did I do that?'
Then it becomes a problem you can work on vs. a reprimand from a shitty boss.
Be kind to yourself.

Fascinating #documentary on the #Challenger space shuttle #disaster. Apparently #NASA withheld quite a bit of #information from the #public for decades.
While it was true the rubber O rings failed due to subfreezing temperatures, NASA ignored engineers warnings and proceeded with the launch. What isn't true is the #astronauts vaporizing due to the #explosion. Withheld #evidence showed not only were they aware, they activated #emergency air tanks and were passengers trapped in a cabin on a #terrifying high speed freefall which slammed into the ocean.
Last month, we released Rx Inspector, a groundbreaking tool that lets you find the factories where your generic drugs were manufactured.
