But what if the side of the brain that is asleep also controls say, your hearing? Or if your left brain is asleep and your right arm goes to sleep too? Hehehehe

Bravus, does this apply to all oceanic mammals?

When is -135^o C (-211^o F) considered a 'high temperature'? When you're talking about 'high temperature superconductors'.

When many metals are cooled to extremely low temperatures, close to 'absolute zero' (-273^o C, -459^o F), they become superconductors. That means they conduct electricity with zero resistance. That might not sound all that exciting, but it allows things like levitation.

See the video

It also means that a current that you start in such a material will keep going for ever, because there's not resistance to stop it.

'High temperature' superconductors don't have to be cooled to the extreme temperatures near absolute zero needed for metal superconductivity (it's very hard to get that cold). They are ceramic materials containing copper, and the record 'hottest' temperature at which superconductivity has occurred is -135^o C.

Questionable factoid: Bullfrogs never sleep

This is a followup to the sleeping (or otherwise) dolphins story. I've heard this about bullfrogs before but never got really good confirmation (or otherwise) on it.

And Amelia, I'm not sure if we've done the research to know whether the deal is the same with the other marine mammals.

This is from Wikipedia:

" Whales and dolphins are also different from humans: they always have to be conscious, as they are conscious breathers, so only one half of their brain sleeps at a time.[9] Sleep becomes difficult to define in lower order animals, such as the bullfrog. Its resting state is too similar to its active state to be considered by many to satisfy the criteria for sleep, but brain activity in the resting state is similar to other amphibians that do meet the criteria when they sleep."

Ah, it's a definitional matter. We know all about those around here. ;)

Now more of a scientist factoid than a science one... in fact, ten of them: Ten Obscure Factoids Concerning Albert Einstein

LOL

Interesting Einstein facts! Didn't he fall in love with his cousin or something?

I don't know how reliable the following is /Bevin

Amazon: Einstein's Wife

From the Back Cover

When Albert Einstein died in 1955 he left behind a remarkable scientific legacy, and an extraordinary secret. In 1986 love letters were discovered which revealed a marriage hidden in the shadows for more than 30 years. Before moving to America in 1933 with his second wife and first cousin Elsa, Einstein had married his university sweetheart and scientific collaborator Mileva Maric.

Einstein, contrary to popular belief, did not work alone in the years leading to the great scientific achievements of 1905. Maric, a brilliant mathematician, collaborated with him on three famous works: Browian Motion, Special Relativity Theory and Photoelectric Effect, which won the Nobel Prize for physics in 1921.

Until now, this collaboration was erased from history. Drawing on long-hidden documents, love letters and biographies, "Einstein's Wife" pieces together a partnership of extraordinary passion and intellect that led to one of the greatest theoretical breakthroughs in the twentieth century.
