The good news is: There are climate friendly alternatives to flying. A train ride can emit as much as 70 times less emissions than a flight.

...also, something that's six years old, but still makes a good point that I intend to make use of in my blog:
https://www.chrisstucchio.com/blog/2014/why_xkcd_style_graphs_are_important.html
xkcd-style sketchy rendering of computer-generated graphs is an important visual cue to drive home to humans (who "don't read") not to assume too much precision or accuracy out of a graph intended more to visualize patterns.
@vickysteeves if "master" means qualified teacher, "magister" is the same word, minus negative connotations, plus sounds fun

Mostly to remind myself, I just want to say that behind all the bullshit, immoral, power-grabbing nastiness of our corporate controlled governments, there are actually nice, normal caring humans in all countries.

uk pol, lgbtq, official parliament petitions
Add gender identity to the characteristics protected under the Equality Act 2010 https://petition.parliament.uk/petitions/301138/
Make LGBT conversion therapy illegal in the UK https://petition.parliament.uk/petitions/300976
Do not ban gender transition treatments for under 18s https://petition.parliament.uk/petitions/318025
Allow for a gender neutral option on a passport, such as an "X" https://petition.parliament.uk/petitions/301083
Remove the criteria for men who have sex with men to wait before donating blood https://petition.parliament.uk/petitions/313693
rule of thumb: if there's an infinte scroll you're probably attention-trapped. go read something else.
boring basic relativity
because
ds^2 = dt^2 - dx^2
ds^2 /dt^2 = 1 - v^2
could really use some latex
boring basic relativity
Why is 4-velocity, the proper time derivative of position, automatically normalized to length 1 (or c, depending on unit convention)?
It is related to the vector (1, 3-velocity) by a factor of gamma, the Lorentz factor. Which also happens to be (?) the inverse of the length of the vector (1, 3-velocity). The Lorentz factor is both the conversion between time and proper time derivative and normalizes 4-velocity.

Slash #CO2, Then Wait—and Wait—for Temperatures to Drop
#ClimateAction taken by the world today wouldn't be noticed for #decades to come, according to researchers who say warming on #Earth won't start to slow down for at least 20 years.
And that's probably an optimistic scenario.
Currently, worldwide #emissions are still #rising.
The situation is similar to a "very large ship, which is at high speed," said Marianne Lund, a #climate #scientist.
