Early Frost Bite

Columbus may have worked the wind
A new and better way to Ind
And also proved the world a ball,
But how about the wherewithal?
Not just for scientific news
Had the Queen backed him for a cruise.

Remember he had made the test
Finding the East by sailing West. 
But had he found it?
Here he was Without one trinket from Ormuz
To save the Queen from family censure
For her investment in his future.

There had been something strangely wrong
With every coast he tried along.
He could imagine nothing barrener.
The trouble was with him the mariner.
He wasn’t off a mere degree;
His reckoning was off a sea.

And to intensify the drama
Another mariner Da Gama

Goodbye, Columbium

This is a rerun from my own bog a couple years ago. It seemed timely.

Christopher Columbus has lost prestige in the New World. First came the historical disputes regarding his claim to priority. But perhaps the most ignominious insult was being downgraded from the Periodic Table.

Finally there's an interesting naming story:
Charles Hatchett's important scientific work was done in the period 1796 to 1806. He was elected a Fellow of the Royal Society in 1797, which is a measure of the esteem in which he was held by his fellow scientists. In 1801 he described in a paper his analysis of a mineral called columbite, named after the location where it had been found in North America. This mineral sample from Massachusetts had lain in the British Museum since 1753. He described the mineral as ".. a heavy black stone with golden streaks ... from Mr. Winthrop": John Winthrop was the first Governor of Connecticut, the source of the mineral. Hatchett showed that the mineral contained a new element and he called it columbium and the mineral columbite, after its place of origin. This year (2001) marks the bicentenary of his discovery. Link
We called Element 41 "columbium" (Cb) for over 150 years until the Euros took it away from us. Van der Krogt:
Element #41 was therefore long known as Niobium as well as Columbium. To end this confusion, at the 15th Conference of the Union of Chemistry in Amsterdam in 1949 the name Niobium was chosen for element #41 and a year later this name was accepted by the International Union of Pure and Applied Chemistry, despite the chronological precedence of the name Columbium. The latter name is still sometimes used in US industry.
Evidence suggests that the Europeans railroaded US out of the name Columbium just to have it for themselves :)

The green color comes from niobium oxide
Niobium is mostly used in steel alloys and for high tech applications. Niobium's use in catalysis plotted versus time looks like a hockey stick: Link  Brazil leads in its production, so in that sense at least, columbium is still New World.

"The Wellcome Trust 2013 winning entry: where did syphilis come from?"

"Did Columbus bring the disease back with him from the New World, or was it in Europe all along? Katherine Wright, winner of the Wellcome Trust science writing prize 2013, investigates"

Here are some excerpts
In the 1490s, a gruesome new disease exploded across Europe. It moved with terrifying speed. Within five years of the first reported cases, among the mercenary army hired by Charles VIII of France to conquer Naples, it was all over the continent and reaching into north Africa.
As its many names attest, contemporaries of the first spread of syphilis did not know where this disease had come from. Was it indeed the fault of the French? Was it God's punishment on earthly sinners?
Another school of thought, less xenophobic and less religious, soon gained traction. Columbus's historic voyage to the New World was in 1492. The Italian soldiers were noticing angry chancres on their genitals by 1494. What if Columbus had brought the disease back to Europe with him as an unwelcome stowaway aboard the Pinta or the NiƱa?
... [S]cientists, anthropologists, and historians still disagree about the origin of syphilis. Did Columbus and his sailors really transport the bacterium back from the New World? Or was it just coincidental timing, that the first cases were recorded soon after the adventurers' triumphant return to the Old World? It seems increasingly likely that Columbus and his crew were responsible for transporting syphilis from the New World to the Old.
Of course, Treponema pallidum was not the only microbial passenger to hitch a ride across the Atlantic with Columbus. But most of the traffic was going the other way: smallpox, measles, and bubonic plague were only some of the Old World diseases which infiltrated the New World, swiftly decimating thousands of Native Americans. Syphilis was not the French disease, or the Polish disease. It was the disease – and the revenge – of the Americas.
