National Geographic on blue whales:

The blue whale, Balaenoptera musculus, is the largest creature ever to live. Linnaeus derived the genus name from the Latin balaena, “whale,” and the Greek pteron, “fin” or “wing.” His species name, musculus, is the diminutive of the Latin mus, “mouse”—apparently a Linnaean joke. The “little mouse whale” can grow to 200 tons and 100 feet long. A single little mouse whale weighs as much as the entire National Football League. Just as an elephant might pick up a little mouse in its trunk, so the elephant, in its turn, might be taken up by a blue whale and carried along on the colossal tongue. Had Jonah been injected intravenously, instead of swallowed, he could have swum the arterial vessels of this whale, boosted along every ten seconds or so by the slow, godlike pulse.

National Geographic, 1,000 Days in the Ice. 1893, Fridtjof Nansen sets out to to reach the north pole. The plan? Build a reinforced boat, intentionally get trapped in the ice, and then sit back and enjoy the three-year ride. Didn’t quite work out, but man, bold plan. If you liked the Shackleton craze of a few years ago, you’ll dig this.

Sounds like the guy was a total stud:

Nansen was a strapping blond man, fair complected, with a frosty stare and a truculent face that seemed slightly at odds with the refinements of his intellect. Nansen stood apart from the quixotic glory hounds who characterized much of polar exploration’s golden age. Call him a Renaissance Viking: He was a gifted writer, a sought-after lecturer, a first-rate zoologist, and a prominent statesman. Fluent in at least five languages, adroit with a camera, he made beautiful maps and illustrations, kept up a voluminous scientific correspondence, and brought an element of cerebral precision to all his explo­rations. A contemporary German scientist said of Nansen that he “knew how to handle the microscope as well as the ice axe and skis,” and his scientific achievements were notable, including a groundbreaking paper on the nature of the central nervous system.

Pursued humanitarian work after his exploring days were over, eventually winning the Nobel Peace Prize in 1922.

National Geographic, The Real Price of Gold …

… on being a Peruvian miner:

For 30 days he faces the dangers that have killed many of his fellow miners—explosives, toxic gases, tunnel collapses—to extract the gold that the world demands. Apaza does all this, without pay, so that he can make it to today, the 31st day, when he and his fellow miners are given a single shift, four hours or maybe a little more, to haul out and keep as much rock as their weary shoulders can bear. Under the ancient lottery system that still prevails in the high Andes, known as the cachorreo, this is what passes for a paycheck: a sack of rocks that may contain a small fortune in gold or, far more often, very little at all.

… on how much there is:

Part of the challenge, as well as the fascination, is that there is so little of it. In all of history, only 161,000 tons of gold have been mined, barely enough to fill two Olympic-size swimming pools. More than half of that has been extracted in the past 50 years.

… on payday:

Together, father and daughter watch the miller perform his ancient art. Using his bare hands, the man swirls several pounds of liquid mercury into a wooden pan to separate the gold from the rock, dumping the mercury-tainted waste into a stream beneath the shed. Thirty feet downstream a young girl is filling up a plastic bottle in the rancid water. But inside the miller’s shed all eyes are focused on the marble-size silvery nugget the miller produces: its mercury-coated exterior hides an unknown quantity of gold.

Ended up being worth about $20.

Okay, they were really writing about sharks, but I still thought this was a fun statistic to include:

Sharks bite fewer people each year than New Yorkers do, according to health department records. And you are far likelier to drown in your bathtub or be murdered by your spouse than you are to die in the jaws of a shark.
