looks like a worthwhile film and an insight into those times.
“The Curies had demonstrated the existence of polonium and radium through their radioactivity, but fellow scientists remained skeptical…. Chemists in particular wanted to see them, to touch them. Only concrete evidence would be persuasive.
and having overloaded our atmosphere with industrially produced CO2, we still are very laissez faire with our discoveries. Like using it freely until it’s too late.
However, the significant downside to using the gas is that it has the highest global warming potential of any known substance. It is 23,500 times more warming than carbon dioxide (CO2).
Just one kilogram of SF6 warms the Earth to the same extent as 24 people flying London to New York return.
It also persists in the atmosphere for a long time, warming the Earth for at least 1,000 years.
Well it’s a hypervalent molecule (the phenomenon is sometimes colloquially known as expanded octet) a molecule that contains one or more main group elements apparently bearing more than eight electrons in their valence shells, having an octahedral geometry, consisting of six fluorine atoms attached to a central sulfur atom.
It certainly buzzes when it meets the right frequency of infrared radiation.

Looks like a great film on many levels. Looking forward to seeing it!
(Wonder if Trump and the misogynistic Luddites and anti-nukers will get worked up over it? Unlike wind turbines, “radioactivity” CAN cause cancer).

Straight question on above. How do a similar number of molecules of gas reflect 23.5k times as much heat as CO2 molecules?

Thanks, am no wiser after long surf. Just accept it is bad sh.t and move on. CO2 has a tiny molecule.
