"chunks of warming dry ice may also break off from the crests of dunes and skid down slopes. This is no ordinary tumble; according to the model, the bases of the chunks are continually sublimating, resulting in a hovercraftlike motion that gouges the dune while propelling the ice down slopes"
sounds like Leidenfrost effect, although this effect normally involves a liquid.

That "divergence over time" actually occurs not that long ago. Right before WW2 everyone on the planet that use Chinese characters use the 1 and only 1 glyph, traditional Chinese. That includes China, Japan, Korea, Vietnam, Hong Kong, Macau, Taiwan.

After WW2 China and Japan tries to simplify the Chinese characters in separate effort, resulting in completely different glyphs and the shitty state of CJK coding we see now.

Korea and Vietnam largely abandoned Chinese characters, may be except for person and place names for clarification reasons.

Hong Kong, Macau, Taiwan all use the same pre-WW2 traditional Chinese glyphs. Thus they have no ambiguity or trouble for exchanging text at all.

FFS just use traditional Chinese glyphs if one want to exchange text with other kanji user. It is the "true" Chinese that everyone in Sinosphere understand for last 3000 years.

Actually you can still use gravitational assist with the sun. Burning your fuel at the perihelion will give you far more delta-V than the same burn at aphelion. Simple explanation: part of the gravitational potential energy of the fuel is converted into kinetic energy of the spacecraft; with the burnt fuel being "left-over" at a much lower orbit than before.

It not just crappy intranet application that are stuck with IE6 which can be easily replaced. Lots of hardware infrastructure are relying on IE6, e.g. lift, surveillance camera, building management systems are all stuck with IE6 for remote management.
Do you expect a large commercial building to replace 1000s perfectly good surveillance camera simply because MS thinks IE6 sucks? Not to mention having to replace all dozens of servers for controlling the cameras? And now we start talking about replacing the lifts....

The solution of this problem is trivial and is left as an exercise for the reader.
