Edward O. Wilson: conoscere la biodiversità per salvare il pianeta

To know well the full biodiversity of Earth is not important simply to add figures to textbooks. The real purpose of science must be the original Linnaean goal: to find and take full account of each and every species of organism on Earth.

Non è mai troppo tardi

Newton aveva 23 anni quando formulò la teoria della forza di gravità. Einstein ne aveva 26 quando pubblicò il paper sull’effetto fotoelettrico che gli fruttò il Nobel 16 anni dopo. Marie Curie studiò la radioattività del radio e del polonio prima dei 30 anni. Secondo uno studio pubblicato ieri, ormai la probabilità di pubblicare uno studio meritevole del Nobel prima dei 30 anni è prossima a 0.

Q&A: Aging Geniuses | The Scientist

Isaac Newton was just 23 years old when, while on a brief hiatus from Cambridge University, he developed his theory of gravitation. “For in those days I was in my prime of age for invention, and minded mathematics and philosophy more than at any time since,” he later wrote in a letter to a fellow scholar.

Similarly, at age 26, Einstein published the paper on the photoelectric effect that would win him a Nobel Prize 16 years later in 1921. Marie Curie was around 30 when she, along with her husband Pierre, discovered the radioactive elements radium and polonium.

But according to economists Benjamin Jones and Bruce Weinberg, young scientists making groundbreaking contributions to their fields are becoming an endangered breed. In a study published yesterday (November 8) in the Proceedings of the National Academy of Sciences, they reported that the chances a Nobel Prize winner at the turn of the 21st century produced their winning work by the age 30 or even 40 is close to zero.

Their analysis of 525 Nobel Prize winners (182 in physics, 153 in chemistry, and 190 in medicine) between 1900 and 2008, revealed that while the mean age at which they did their Nobel-prize winning work was around 37 for the three fields in the early 20th century, they are now around 50, 46, and 45 for Physics, Chemistry, and Medicine, respectively. The Scientist spoke to Weinberg, a microeconomist at Ohio State University, and Jones, a macroeconomist at the The Kellogg School of Management, Northwestern University, about the trends in age and creativity in science, and what they may mean for the future of science research.

Idee degli anni Ottanta

Da qualche giorno sono alla ricerca delle idee degli anni Ottanta che sarebbero alla base delle proposte di Matteo Renzi.

Finora le migliori che ho trovato sono queste:

Oh yeah
In France a skinny man
Died of a big disease with a little name
By chance his girlfriend came across a needle
And soon she did the same
At home there are seventeen-year-old boys
And their idea of fun
Is being in a gang called The Disciples
High on crack, totin’ a machine gun

Time, time

Hurricane Annie ripped the ceiling of a church
And killed everyone inside
U turn on the telly and every other story
Is tellin’ U somebody died
Sister killed her baby cuz she couldn’t afford 2 feed it
And we’re sending people 2 the moon
In September my cousin tried reefer 4 the very first time
Now he’s doing horse, it’s June

Times, times

It’s silly, no?
When a rocket ship explodes
And everybody still wants 2 fly
Some say a man ain’t happy
Unless a man truly dies
Oh why
Time, time

Baby make a speech, Star Wars fly
Neighbors just shine it on
But if a night falls and a bomb falls
Will anybody see the dawn
Time, times

It’s silly, no?
When a rocket blows up
And everybody still wants 2 fly
Some say a man ain’t happy, truly
Until a man truly dies
Oh why, oh why, Sign O the Times

Time, time

Sign O the Times mess with your mind
Hurry before it’s 2 late
Let’s fall in love, get married, have a baby
We’ll call him Nate… if it’s a boy

Time, time

Time, time
