American conquistador

William Walker may have been one of the 19th century's most brilliant minds. He graduated from the University of Tennessee in 1838, at the tender young age of 14, then went to medical school, law school and briefly served as editor of the New Orleans Crescent, all before he was 25. He also happened to be extremely proud and aggressive -- a winning combination that saw got him wounded in two duels as a young man -- and, unfortunately, a big racist. This latter trait surely contributed to the development of what would be his lasting legacy: the filibuster.

We don't mean the legislative stall tactic used by long-winded politicians; back then, "filibuster" meant "a private individual who engages in unauthorized warfare against a foreign country, often with the intent of overthrowing the existing government." In Walker's case, it was Latin America -- specifically Nicaragua, though his ambitions weren't limited to that country. Wikipedia:

"In 1853, he unsuccessfully attempted to stage an insurrection in the Mexican states of Sonora and Baja California. Later, when a path through Lake Nicaragua was being considered as the possible site of a canal through Central America, he was hired as a mercenary by one of the factions in a civil war in Nicaragua. In 1856 he declared himself commander of the country's army and soon after President of the Republic. After attempting to take control of the rest of Central America and receiving no support from the U.S. government, he was defeated and eventually executed by the local authorities he tried to overthrow."

Almost as fascinating (and frightening) as what Walker did was what he tried to do. Convincing many Southerners of the desirability of creating a slave-holding empire in tropical Latin America, he enjoyed great popularity in the South, where he was referred to as "the grey-eyed man of destiny" and "General Walker." ("Destiny," after all, was a hot-button word when it came to American expansionism.) He died before he could capitalize on much of that political power, just a few months before the nation was convulsed by the Civil War.

6 Radiant Facts About Irène Joliot-Curie

Though her accomplishments are often overshadowed by those of her parents, the elder daughter of Marie and Pierre Curie was a brilliant researcher in her own right.

1. SHE WAS BORN TO, AND FOR, GREATNESS.

Irène’s birth in Paris in 1897 launched what would become a world-changing scientific dynasty. A restless Marie rejoined her loving husband in the laboratory shortly after the baby’s arrival. Over the next 10 years, the Curies discovered radium and polonium, founded the science of radioactivity, welcomed a second daughter, Eve, and won a Nobel Prize in Physics. The Curies expected their daughters to excel in their education and their work. And excel they did; by 1925, Irène had a doctorate in chemistry and was working in her mother’s laboratory.

2. HER PARENTS' MARRIAGE WAS A MODEL FOR HER OWN.

Like her mother, Irène fell in love in the lab—both with her work and with another scientist. Frédéric Joliot joined the Curie team as an assistant. He and Irène quickly bonded over shared interests in sports, the arts, and human rights. The two began collaborating on research and soon married, equitably combining their names and signing their work Irène and Frédéric Joliot-Curie.

3. SHE AND HER HUSBAND WERE AN UNSTOPPABLE PAIR.

Their passion for exploration drove them ever onward into exciting new territory. A decade of experimentation yielded advances in several disciplines. They learned how the thyroid gland absorbs radioiodine and how the body metabolizes radioactive phosphates. They found ways to coax radioactive isotopes from ordinarily non-radioactive materials—a discovery that would eventually enable both nuclear power and atomic weaponry, and one that earned them the Nobel Prize in Chemistry in 1935.

4. THEY FOUGHT FOR JUSTICE AND PEACE.

The humanist principles that initially drew Irène and Frédéric together only deepened as they grew older. Both were proud members of the Socialist Party and the Comité de Vigilance des Intellectuels Antifascistes (Vigilance Committee of Anti-Fascist Intellectuals). They took great pains to keep atomic research out of Nazi hands, sealing and hiding their research as Germany occupied their country, Irène also served as undersecretary of state for scientific research of the Popular Front government.

5. SHE WAS NOT CONTENT WITH THE STATUS QUO.

Irène eventually scaled back her time in the lab to raise her children Hélène and Pierre. But she never slowed down, nor did she stop fighting for equality and freedom for all. Especially active in women’s rights groups, she became a member of the Comité National de l'Union des Femmes Françaises and the World Peace Council.

6. SHE WORKED HERSELF TO DEATH.

Irène’s extraordinary life was a mirror of her mother’s. Tragically, her death was, too. Years of watching radiation poisoning and cancer taking their toll on Marie never dissuaded Irène from her work. In 1956, dying of leukemia, she entered the Curie Hospital, where she followed her mother’s luminous footsteps into the great beyond.

You Can Now Order Food Through Facebook

After a bit of controversy over its way of aggregating news feeds and some questionable content censoring policies, it’s nice to have Facebook roll out a feature everyone can agree on: allowing you to order food without leaving the social media site.

According to a press release, Facebook says that the company decided to begin offering food delivery options after realizing that many of its users come to the social media hub to rate and discuss local eateries. Rather than hop from Facebook to the restaurant or a delivery service, you’ll be able to stay within the app and select from a menu of food choices. Just click “Order Food” from the Explore menu on a desktop interface or under the “More” option on Android or iOS devices. There, you’ll be presented with options that will accept takeout or delivery orders, as well as businesses participating with services like Delivery.com or EatStreet.

If you need to sign up and create an account with Delivery.com or Jimmy John’s, for example, you can do that without leaving Facebook. The feature is expected to be available nationally, effective immediately.
