Celebrate #EngineersWeek2016: #TBT Hedy Lamarr Is Famous As A Glamorous Movie Star From The Black-and-white
Celebrate #EngineersWeek2016: #TBT Hedy Lamarr is famous as a glamorous movie star from the black-and-white era of film. But what most people don't know about her is that, in 1942, she co-invented a device that helped make possible the development of GPS, Bluetooth, and Wi-Fi technology! Born in Austria in 1914, the mathematically talented Lamarr moved to the US in 1937 to start a #Hollywood career. Throughout the 1930s and 1940s, she was considered one of cinema's leading ladies and made numerous films; however, her passion for engineering is far less known today. Her interest in inventing was such that she set up an #engineering room in her house complete with a drafting table and wall of engineering reference books. With the outbreak of World War II, Lamarr wanted to apply her skills to helping the war effort and, motivated by reports of German U-boats sinking ships in the Atlantic, she began investigating ways to improve torpedo technology. After Lamar met composer George Antheil, who had been experimenting with automated control of #musical instruments, together they hit on the idea of "frequency hopping." At the time, radio-controlled torpedoes could easily be detected and jammed by broadcasting interference at the frequency of the control signal, thereby causing the #torpedo to go off course. Lamarr and Antheil were granted a patent for their invention on August 11, 1942, but the US #Navy wasn't interested in applying their groundbreaking technology until twenty years later when it was used on #military ships during a blockade of Cuba in 1962. Lamarr and Antheil's frequency-hopping concept serves as a basis for the spread-spectrum communication #technology used in #GPS, #WiFi and #Bluetooth devices. Unfortunately, Lamarr's part in its development has been largely overlooked and her efforts weren't recognized until 1997, when the Electronic Frontier Foundation gave her an award for her technological contributions. Hedy Lamarr passed away in 2000 at the age of 85 and, in 2014, she was at long last inducted into the National Inventors Hall of Fame for her invention of a "Secret Communication System" many years ago.

All Known Planets Prior to 1992, the only planets we knew of for certain were the nine (now eight) in our own solar system. However, in recent years, we have discovered many circling other stars. In fact, as of June 2012, we know of 778 extra-solar planets (+8 of our own = 786 total). Here they all are, shown to scale.

Happy Birthday to you Dr. Seuss! Theodor Seuss Geisel was an American writer and illustrator best known for authoring popular children's books under the pen name Dr. Seuss. Theodor Seuss Geisel was born in Springfield, Massachusetts, to Theodor Robert and Henrietta (née Seuss) Geisel. All of his grandparents were German immigrants. His father managed the family brewery and was later appointed to supervise Springfield's public park system by Mayor John A. Denison after the brewery closed because of Prohibition. Mulberry Street in Springfield was made famous in Dr. Seuss' first children's book "And to Think That I Saw It on Mulberry Street!" and is less than a mile southwest of his boyhood home on Fairfield Street. Geisel was raised a Lutheran. He enrolled at Springfield Central High School in 1917 and graduated in 1921. He took an art class as a freshman and later became manager of the school soccer team. #DrSeuss
Orange Battery Artistic Scientist Generates Electricity Back to Light is a creatively scientific series by photographer Caleb Charland that explores the naturally electrifying power of ordinary objects like fruits and loose change. The images in the series features a number of materials, including consumables readily found in one's pantry, generating enough power to light lamps and LED lights. We had previously seen Charland light a lamp with 300 apples, but now the grocery list has expanded to include oranges, lemons, limes, grapefruits, pomelos, and vinegar. http://bit.ly/15xVIBf
Academics in a Box Inc. was founded to inspire in students a desire to learn more about the sciences and humanities. Our products aim to allow students a new way to experience the beauty, poetry, and wonder of our universe through hands-on experience. Our foundation is based on the ideas that by “doing” and “experiencing,” students are more motivated to become inquisitive about the world around them. It’s this curiosity and creative thinking that are at the heart of developing a love of learning. The Next Generation Science Standards (NGSS) is used as a guide to ensure that our products supplement the learning that takes place in the classroom. We aim to take students beyond simple memorization of facts and figures by helping them gain a better understanding of significant science, technology, engineering, and mathematics (STEM) practice and application, as well as gain a deeper appreciation of the materials they are presented with.
