Could a Mathematical Formula stop the extinction of species?

Math has already been used effectively in defining protected areas in places with productive activities in 150 countries over the past 15 years. The best example of that application is Australia's Great Barrier Reef, where a software called Marxan permitted the expansion of protected areas from 5 percent to 35 percent while preserving species and improving fishing.

The U.S. Census Bureau estimates that the Hispanic population in the U.S. will reach 132.8 million (or 30 percent of the total U.S. population) by the year 2050.   But Latino students, along with other minorities, continue to be underrepresented in the STEM disciplines and to receive STEM degrees at a lower rate than their White counterparts. Latino students are more likely than Whites to be exposed to funding inequities and to have science teachers who did not major in science.

The cheapest trip to Mars probably won’t leave from Cape Canaveral but from a tiny Indian island called Sriharikota. The island has become the Launchpad of the Indian Space Program, that has shot more than 120 satellites into orbit until today, and at a much more competitive price than its competitors.

India competes for commercial launches with space agencies in Europe and Japan, and with private players such as Elon Musk’s Space Exploration Technologies Corp. and Jeff Bezos’s Blue Origin LLC.

Filantropía en la era de la diversidad

El mundo de la filantropía evoca imágenes de hombres y mujeres adinerados luciendo tuxedos y pieles en fiestas y galas de lujo. El estereotipo es merecido - generaciones de ricos patrones donando generosamente su dinero y prestigio a un selecto grupo de fundaciones, año tras año, creando un sólido sistema, aunque también elitista, rehogado en una buena dosis de tradición y ego.

Philantropies in the age of diversity

The world of philanthropy conjures images of well-heeled men and women donning tuxedos and furs at fancy galas. The stereotype is well-deserved - generations of wealthy patrons lavishly contributed money and prestige to a select group of foundations over the generations, creating a robust yet exclusionary system steeped in tradition and ego.

The official recording of the science we now called History began 484 years before Jesus Christ.

OP-ED: Sr. Lee Iacocca, por favor visítenos en el Filadelfia Latino

Me encontré con este libro de nuevo esta semana, inicialmente lo recogí hace varios años en una tienda de Barnes & Noble en Filadelfia.

Es un libro que el ex director general de la Corporación Chrysler, el Sr. Lee Iacocca, escribió, después de su cambio mágico y también polémico de la empresa fabricante de automóviles, quien es una de las "Tres Grandes" en Estados Unidos.

OP-ED: Mr. Lee Iacocca, please come visit us in Latino Philadelphia

I came across this book again this week, after I first picked it up several years ago in a Barnes & Noble Store in Philadelphia.

It is a book the former CEO of Chrysler Corporation, Lee Iacocca, wrote, after his magical and also controversial turnaround of the car manufacturer company, one of the "Big Three" in America.
