Why do you find that particular theory about the Cambrian Explosion compelling? I assume mankind is putting a similar pressure on many ecosystems today, so shouldn’t we be seeing that kind of evolutionary explosion happening now?

According to Wikipedia, it originated in ancient Greece and has always meant the same thing as it does now.
I took it to be contrasting the “thrill of discovery” with doing math that would be boring and tedious to most people.
What does it mean to “smoke weed” in this context?
Oh, that makes a lot more sense now. I didn’t see the “trans” and “CIS” on the side.
“Look at the birds of the sky, that they do not sow, nor reap, nor gather crops into barns, and yet your heavenly Father feeds them.”
Can somebody explain this one?
Just because you shouldn’t trust them doesn’t mean you’re not allowed to interact with them. It just means you need to be careful.
“Energy is conserved in general relativity, it’s just that you have to include the energy of the gravitational field along with the energy of matter and radiation and so on.”
Quote taken from Atzanteol’s article.
Further into the article he says that, "It would be irresponsible of me not to mention that plenty of experts in cosmology or GR would not put it in these terms. We all agree on the science; there are just divergent views on what words to attach to the science. In particular, a lot of folks would want to say “energy is conserved in general relativity, it’s just that you have to include the energy of the gravitational field along with the energy of matter and radiation and so on.” "
So energy is conserved on the whole, it’s just not conserved if you consider photons apart from their greater context.
“The planet’s atmosphere would feature something akin to Earth’s water cycle, but instead with sand cycling between solid and gaseous states. From the hotter, lower levels of the atmosphere, with temperatures close to 1,000C, silicate vapour would rise up, cool and form microscopic grains of sand, too small to see. Eventually, these clouds of sand dust would become dense enough that they begin to rain back down to the lower layers of the atmosphere. Below a certain level, the sand would sublime back into vapour, completing the cycle.”
I find that the default Samsung Notes app is actually pretty good.

“Fireballs and bolides are astronomical terms for exceptionally bright meteors that are spectacular enough to to be seen over a very wide area. … A fireball is an unusually bright meteor that reaches a visual magnitude of -3 or brighter when seen at the observer’s zenith. … Fireballs that explode in the atmosphere are technically referred to as bolides although the terms fireballs and bolides are often used interchangeably.”
