July 29th: National & International Days, Celebrations and Observances

July 29 packs quite a mix of events and causes.

• Tigers need our help. WWF's protection teams work tirelessly in the field, while local anti-poaching units keep watch. A quick social media post about these endangered cats might inspire others to pitch in.
• Cooking enthusiasts across the country are heating up their ovens for National Lasagna Day. Skip the meat and stack those layers with fresh veggies instead - your planet will thank you.
• Nobody talks enough about head and neck cancer symptoms. Share what to watch for with your loved ones. On a lighter note, local weather enthusiasts are meeting up to track rainfall patterns today.
• Gather some friends and sample different chicken wing recipes. Local farms offer the best choices for quality meat.
• Time to sort that makeup drawer. Those old lipstick tubes cluttering your vanity? Many brands now run recycling programs.
• Local milk banks always welcome donations. And if you know any new moms, pass along info about breastfeeding support groups in your area.

Three separate dates mark July 29's place in science and education.

• Augustin Fresnel upended accepted science in 1818. Working in France, his research revealed light moved in waves - not the straight lines Newton had described. His peers took notice. By 1819, the French Academy of Sciences awarded him their top honor.
• The atomic age needed oversight. In 1957, eighty-one countries met in Vienna to address this need. They created the International Atomic Energy Agency, with W. Sterling Cole taking the helm as its first director.
• A simple camping trip in 1907 grew into something much larger. On England's Brownsea Island, Robert Baden-Powell gathered twenty boys between ten and sixteen years old. Each paid one pound to attend.

He split them into four patrols - Wolves, Ravens, Bulls, and Curlews. Their activities from August 1-9 worked so well that Baden-Powell knew he'd found the right formula. The Scout movement spread from these modest beginnings.

July 29 links an unlikely group of pioneers - from mountain climbers to chemists to social reformers.

• Betty Harris tackled safety problems at Los Alamos Lab head-on in the 1940s. Her methods for finding hidden explosives earned several patents. Lab workers today still use her techniques for handling dangerous materials, and her safety standards protect both people and surroundings.
• Jim Bridwell's rock faces changed forever under Jim Bridwell's influence. From 1944 until his death in 2018, he opened new routes that nobody thought possible. After too many climbers got hurt, he created the park's first rescue team. His gentle climbing style taught others to scale peaks without damaging them.
• Maria L. de Hernández saw how Mexican-American neighborhoods struggled without basic services. Through nine decades (1896-1986), she pressed officials for change. She helped launch LULAC and demanded clean water for forgotten communities. The parks and health centers she fought for still serve urban families.
• Gideon Henderson reads climate history in ocean chemistry. His findings about sea changes now shape Britain's environmental choices through his role as DEFRA's lead scientist.
• Denis Urubko studies glaciers where few dare to go. He's reached all fourteen 8,000-meter summits breathing only thin mountain air. His notes from these climbs help scientists track how the world's highest peaks are changing.
