1. That was so well done!

I was blown away.

We owe so much to that great scientist who did the research that showed the dangers of lead poisoning.

And indeed how similar to the idiots who try to dismiss climate change, or any other important topic.

I'll have to catch the replay later this week.

all the COSMOS episodes.

Many we know about, but we can always learn more.

9. Did removing lead from petrol spark a decline in crime?

Working away in his laboratory in 1921, Thomas Midgley wanted to fuel a brighter tomorrow. He created tetraethyl lead - a compound that would make car engines more efficient than ever.

But did the lead that we added to our petrol do something so much worse? Was it the cause of a decades-long crime wave that is only now abating as the poisonous element is removed from our environment?

For most of the 20th Century crime rose and rose and rose. Every time a new home secretary took office in the UK - or their equivalents in justice and interior ministries elsewhere - officials would show them graphs and mumble apologetically that there was nothing they could do to stop crime rising.

Then, about 20 years ago, the trend reversed - and all the broad measures of key crimes have been falling ever since.

Offending has fallen in nations whose governments have implemented completely different policies to their neighbours.

7. I siphoned leaded gas when I was younger.

It was way different than today's unleaded blend. Neither is pleasing to the palate, but the leaded stuff will make you vomit immediately. It's uncontrollable.

Did I mention that I siphoned leaded gas when I was younger?

10. It's been uneven, but this was one of the best

I think Cosmos has suffered a bit in its second incarnation from having too many resources. A couple of the episodes have just been all over the place, from sound waves to subatomic particles to supernovae with hardly any focus except the opportunity to show cool graphics. Carl Sagan had to carefully consider what he wanted to use to fill his time and how it fit together. This episode, linking the pure science of the age of the Earth and the crass denialists of global lead poisoning, was beautiful though.

11. It was no accident.......

That the episode parralleled the right wing funded "science" used as "evidence" by the right wing that climate change is occuring.

I admire what Tyson is doing to try to inspire the next generation to question everything and learn the truth from themselves, instead of just trusting what the right wing tells them.
