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.

y'all
adding #science #fact #reason to your political opinion doesn't make it right
neither does one study. I don't believe there's been an honest attempt to engage with the literature.
the trend is also the fault of those who fall for it
let's shut out the stembro contingent by
- holding points self-tagged as particularly scientific to correspondingly high standards, no boosts if you aren't sure it's our collective best attempt at an honest representation.
- flood some actual, boring, unsexy, everyday science into the #science tag.

Markus Krall fordert, wer #HartzIV bekommt, dem soll das #Wahlrecht entzogen werden. Die #AfD hofiert ihn. Z.B. heute Abend zusammen mit #Meuthen. Gleichzeitig stellt sich die AfD als "Partei des kleinen Mannes" dar.
