Philosophers should talk more about climate change. Yes, philosophers. By Sabine Hossenfelder
Evidenzia (giallo) - Posizione 6
how many scientists don’t know how science works
Nota - Posizione 7
É scioccante
Evidenzia (giallo) - Posizione 7
Most of those I have to deal with still think Popper was right
Evidenzia (giallo) - Posizione 7
falsifiability
Evidenzia (giallo) - Posizione 9
I should, for example, be able to publish a paper predicting that tomorrow the sky will be pink and next Wednesday my cat will speak French.
Nota - Posizione 10
Sarebbero paoer scientifici xché falsificabili
Evidenzia (giallo) - Posizione 12
Popper’s idea of telling science from non-science by falsifiability “has the untoward consequence of countenancing as ` scientific’ every crank claim
Nota - Posizione 13
Larry laudan
Evidenzia (giallo) - Posizione 14
almost all of today’s philosophers of science agree that falsification is not a sufficient criterion of demarcation
Evidenzia (giallo) - Posizione 17
when it is scientifically justified to amend a theory whose predictions ran into tension with new data.
Nota - Posizione 17
Lo scipo del post
Evidenzia (giallo) - Posizione 18
science cannot work without Occam’s razor.
Nota - Posizione 18
Tesi
Evidenzia (giallo) - Posizione 19
among two theories that describe nature equally well you should take the simpler
Nota - Posizione 19
Definizione del rasoio
Evidenzia (giallo) - Posizione 20
We would be permitted, for example, to add the assumption “all particles were made by god”
Nota - Posizione 21
Ma alla scienza nn serve. Imo: e come spiego ciò che osservo?
Evidenzia (giallo) - Posizione 22
the phrase that two theories “describe nature equally well” and you should “take the simpler one” are somewhat vague.
Nota - Posizione 23
Problema
Evidenzia (giallo) - Posizione 25
it’s unscientific to make assumptions which are unnecessary to explain observation
Nota - Posizione 25
Ripetiamo il rasoio
Evidenzia (giallo) - Posizione 26
They invent particles which make theories more complicated and are of no help to explain existing data.
Nota - Posizione 27
L errore di molti fisici
Evidenzia (giallo) - Posizione 30
We’d have biologists writing papers about flying pigs and then hold conferences debating how flying pigs poop because, who knows, we might discover flying pigs tomorrow.
Nota - Posizione 31
Se i biologi procedessero come certi fisici
Evidenzia (giallo) - Posizione 33
math certainly comes in handy for particle physicists because it prevents mere mortals from understanding just what the physicists are up to.
Nota - Posizione 34
L errore é mascherato dalla matematica
Evidenzia (giallo) - Posizione 35
I have recently had to deal with a lot of climate change deniers
Evidenzia (giallo) - Posizione 36
I must be a denier too because, drums please, I am an outspoken critic of inventing superfluous particles.
Nota - Posizione 36
La tesi negazionista
Evidenzia (giallo) - Posizione 38
common deniers’ complaint that climate scientists adapt models when new data comes in.
Nota - Posizione 38
Premessa
Evidenzia (giallo) - Posizione 39
it’s exactly the same thing that all these physicists do each time their hypothetical particles are not observed!
Nota - Posizione 39
Secondo deniers
Evidenzia (giallo) - Posizione 41
Then someone yells “Epicycles!”
Evidenzia (giallo) - Posizione 43
Revising a hypothesis when new data comes in is perfectly fine.
Evidenzia (giallo) - Posizione 44
Sometimes this means you actually need a new theory. Sometimes you have to adjust one
Evidenzia (giallo) - Posizione 48
Indeed, adding epicycles to make the geocentric model of the solar system fit with observations was entirely proper scientific methodology.
Nota - Posizione 49
Sorpresa
Evidenzia (giallo) - Posizione 50
Astronomers of the time could have proceeded this way until they’d have noticed there is a simpler way to calculate the same curves,
Evidenzia (giallo) - Posizione 52
What scientists should not do, however, is to adjust details of a theory that were unnecessary in the first place.
Nota - Posizione 53
Il divieto
Evidenzia (giallo) - Posizione 53
Kepler for example also thought that the planets play melodies on their orbits around the sun, an idea that was rightfully abandoned because it explains nothing.
Nota - Posizione 54
Esempio
Evidenzia (giallo) - Posizione 54
adding dark matter and dark energy to the cosmological standard model in order to explain observations is sound scientific practice.
