Interesting story about the origin of feathers. They evolved earlier than we thought: https://www.sciencedaily.com/releases/2018/12/181217125908.htm

Beautiful plumage !

Thanks for telling about that article Rumpole.

The world would certainly be a different place with out Nikola Tesla.

Also a pity he did not greatly benefit from his genius.

He was taken for a ride by Edison et al.

This study puts global warming of the oceans in perspective. Quite frightening, really. https://www.theguardian.com/environment/2019/jan/07/global-warming-of-oceans-equivalent-to-an-atomic-bomb-per-second

Very disturbing indeed.

Very disturbing indeed.

1 atomic bomb/second is the equivalent of 86,400 atomic bombs/day or 31.54 million atomic bombs per year.

Very disturbing indeed.

1 atomic bomb/second is the equivalent of 86,400 atomic bombs/day or 31.54 million atomic bombs per year.

Surely the planet's life would be measured in days, if not hours with an onslaught like that. A truly terrifying prospect.

The heat from an atomic bomb is thermal energy, which is around 30-40% of the bomb's total blast energy, so the story is a little misleading from that perspective. It would have been more accurate to have said the heating of the ocean is equivalent to the thermal energy of one atomic bomb/second or the total energy of one atomic bomb every 2.5 to 3.3 seconds.  But it is still a lot of heat.
