FYI: https://en.wikipedia.org/wiki/Faint_young_Sun_paradox Solar radiation intensity has been increasing gradually since the earth was formed. Current sun intensity may not allow for the same CO2 concentrations that e

> Most modern FORTH don't have SMUDGE any more, which has been replaced by HIDE and REVEAL. I think, the modern Forths (i.e. since 1994 ANS Forth standard) need neither HIDE nor REVEAL as these are made superflous by RECURSE. Other

There's another parser generator written in Forth, that I have personally used myself: Gray [1-3] The zip file [1] has english documentation, the papers [2,3] are unfortunately only available in german. This [4] is a mostly working gra

Also the ELT (claimed to be operational starting in 2025) [1] will already allow study of the atmospheric composition of extrasolar planets (I guess that means spectroscopy). [1] https://en.wikipedia.org/wiki/Extremely_

The right way to look at extreme weather events in the climate change context is via Attribtion Science. Stated simplistically this looks at "how often would these kind of extremes happen in a world with normal normal levels of CO2&qu

Same idea stated differently: the problem is the amount of carbon available at the planet's surface: a huge portion of that carbon will eventually end up as CO2, as that is the lowest energy state. Earth's biosphere allows for a

I don't know anything about chainsaws, but the parent mentioned being able to remove the chainsaw's battery pack. With enough batteries, and maybe concurrent charging, any length of cutting sessions should be possible.

You can also do "multiline multiliners" by adding a target .ONESHELL. By overriding the variable SHELL, this allows you to put arbitrary multi-line scripts of your preferred programming language into makefile recipes. https:&#x2

I'd assume that the power grid is much more vulnerable than that at least some of the time in some regions. What if due to natural load variations the network already is close to the capacity reserve (which could be measured by tracki

I think western governments also manage their environmental impact downwards only as much as is possible without redistributing significant amounts of resources to the problem. I.e. they currently only look at lower hanging fruit , and to

I think it's not so much a question of material degradation due to humidity. The problem is low outside air temperature (-50 deg celsius?) leading to low inside surface temperature leading to condensation which is also a problem WRT c

It would be very cool to have a binary black hole system somewhere in the solar-system. I.e. two black holes in a tight orbit around each other at very high orbital velocities. This could allow for very powerful slingshots to bring probes

I don't think that this would work: whoever is holding the alternator would also be pulled into the black hole while generating the electricity. Maybe the "right" way to convert potential energy is via conversion to heat and

Another idea would be to use the black hole as a gravitational lens to construct a large telecscope. I wonder what the focal length and the effective lense diameter would be. Also the orbital velocity of the image sensor (in orbit around

I think the most obvious way to utilize a close-to-earth black hole is for space-flight. By utilizing the Oberth effect [1] it is possible to gain extra kinetic energy when firing engines very deep inside the black hole's gravity-well
