Hot news from hot Venus

2015-05-20 ISAS seminar

Speaker:    Dr.Javier Peralta (ITYF, ISAS)
Title:      Hot news from hot Venus
Abstract:
After decades of space exploration, the misterious Earth's twin planet
jealously keeps most of its secrets hidden below its persistent cloud
coverage. Despite both planets were certainly born as nearly identical
bodies, Venus' cruel fate has condemned it to hell conditions for life
in its obscured surface, at the time that its atmosphere is a living
paradox where the planet rotates as slow as fast its atmosphere is. And
the history of its exploration clearly teaches a simple rule: Venus is
never as expected.

The subject of Heisenberg’s doctoral dissertation, however, wasn’t quantum physics. It was harder than that. The 59-page calculation that he submitted to the faculty of the University of Munich in 1923 was titled “On the stability and turbulence of fluid flow.”

... with the sketches of wild water flows made by Leonardo da Vinci in the 15th century.
