Erwin Schrödinger coined the term ‘wave mechanics’ (or Wellenmechanik) on this day in 1926 in a letter to Albert Einstein.

He had been inspired by a footnote in a paper by Einstein to model movement of an electron around a nucleus as a wave rather than orbiting particle.

To celebrate, enjoy these waves of a different sort from Lawrence Bragg’s 1950 series, The Nature of Things.


On this day, President Bush signed the Arizona Desert Wilderness Act of 1990 into law, which established 38 new wilderness areas and expanded the Aravaipa Canyon wilderness.  The bill also established the Gila Box Riparian National Conservation Area featured here.

The 23,000-acre Gila Box Riparian NCA is truly an oasis in the desert. It has four perennial waterways - the Gila and San Francisco rivers and Bonita and Eagle creeks, which are the lifeline for this remarkable place. The Gila River canyon section, known as the Gila Box, is composed of patchy mesquite woodlands, mature cottonwoods, sandy beaches, and buff-colored cliffs. Bonita Creek, popular for birdwatching, hiking, and picnicking, is lined with large cottonwoods, sycamores, and willows. The perennial creek and riparian vegetation make this a cool year-round desert oasis.

Cliff dwellings, historic homesteads, Rocky Mountain bighorn sheep and over 200 species of birds make this year-round watery desert refuge worth the short drive from Safford, Arizona.

RMS Titanic Departs Southampton

It was at noon on this day in history, 10 April 1912, that RMS Titanic departed Southampton, England, on her maiden voyage. The ship’s whistle blew 3 times to mark the start of the journey. Her next destinations were Cherbourg, France, and Queenstown, Ireland, to pick up further passengers before turning to cross the Atlantic Ocean.


Happy Birthday, Oregon!

They say that “Virginia is for lovers.”  But it’s Oregon that was born 156 years ago today, on Valentine’s Day.  Maybe that’s why there are so many things to love about BLM-managed lands in Oregon, more than 15 million acres of forests, rangelands, beaches, mountains and more!

On this day in 2002, Red Hot Chili Peppers released their eighth studio album, By The Way.

Produced by Rick Rubin.

In the February 18, 1961 issue of the Saturday Evening Post, James M. Stewart ‘32 wrote of his time at Princeton, “In the end I was graduated in architecture with honors. I even won a scholarship, pointing toward a master’s degree in architecture if I wanted to accept. But my first Triangle show led me to another career.” We think it worked out well for him.

Stewart is pictured here charming cross-dressing classmate H. H. Dunham '32 in the Triangle Club’s 1930 production of The Tiger Smiles.

On This Day
26 August 1789 Declaration of the Rights of Man and of the Citizen

In 1789 the people of France brought about the abolishment of the absolute monarchy and set the stage for the establishment of the first French Republic. Just six weeks after the storming of the Bastille, and barely three weeks after the abolition of feudalism, the Declaration of the Rights of Man and of the Citizen was adopted by the National Constituent Assembly as the first step toward writing a constitution for the Republic of France.

#OnThisDay in #1984, one day before his 45th Birthday, #MarvinGaye was shot dead by his father at his parent’s home in Los Angeles, California. The argument started after his parents squabbled over misplaced business documents, Gaye attempted to intervene, and was killed by his father using a gun he had given him four months before. Marvin Sr. was sentenced to six years of probation after pleading guilty to manslaughter. Charges of first-degree murder were dropped after doctors discovered Marvin Sr. had a brain tumour. #TWIMH
