John Tyndall was born on this day in 1820.

A prominent 19th century physicist, he is famous for his studies in diamagnetism, proving why the sky is blue and most importantly for his researches on the action of radiant heat or infrared radiation, which led to him proving the Greenhouse effect.

Tyndall was also a keen mountaineer becoming the first person to climb the Weisshorn in 1861. His interest was so great that he also turned his scientific researches to glaciers and the study of ice.

All of this and he was quite a natty dresser too.


Happy Birthday, Jupiter Inlet Lighthouse ONA in Florida!

The Jupiter Inlet Lighthouse Outstanding Natural Area is part of the BLM’s National Conservation Lands, and the only complete unit east of the Mississippi River.  The ONA was established on this day in 2008 and is cooperatively managed in a unique partnership between the BLM and local partners. 

The Jupiter Inlet Lighthouse ONA is located at the confluence of the Loxahatchee River and Indian River Lagoon, just ¼ mile from the Atlantic Ocean in southeastern Florida.

The ONA offers a range of recreation activities, from exploring the cultural and military history associated with the historic 1860 lighthouse to exploring the trails of natural Florida. For the more adventurous, kayaking the ONA’s shoreline and exploring its lagoon offer unique views of the lighthouse and the opportunity to get close to manatees.

Learn about the birthday celebration today at the Jupiter Inlet Lighthouse ONA - also a National Conservation Lands 15th anniversary event:  http://www.facebook.com/BLMJupiterInlet. Follow all 2015 anniversary events and activities with #conservationlands15.

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.

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.

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!
