2015 LFL National Conference – Fearfully and Wonderfully Made with Dr. David Menton
Nearly 400 Lutherans gathered October 30-31 at both the Cincinnati Airport Marriott and the Creation Museum in Petersburg, Kentucky, from across the United States and Canada for the 2015 Lutherans For Life National Conference. The theme: Created • Redeemed • Called.
“Dr. David Menton was born in Mankato, Minnesota, and grew up as an only child in a Christian family. He was blessed to share God’s Word as a Sunday school teacher, church elder, and president of the congregation. Since early grade school, Dr. Menton has had a strong interest in science of all kinds. While in grade school, he converted a small room in the basement into a well-equipped chemistry laboratory. Many of the birthday and Christmas gifts he received during childhood were of a scientific nature, including a chemistry set, mineralogy collection, microscope, telescope, and binoculars. This lifelong interest in science led to his study of biology and chemistry at Minnesota State University in Mankato, where he graduated with a BS degree in 1959. After a six-month tour of active duty in the Army Reserves, Dr. Menton worked two years as a research laboratory technician at the Mayo Clinic in Rochester, Minnesota. He left Mayo to do graduate work at Brown University in Providence, Rhode Island, where he received a PhD in biology in 1966. His thesis research dealt with the effects of essential fatty acid deficiency on the structure and epidermal barrier function of skin. Following graduation from Brown, Dr. Menton accepted a position in the department of anatomy at Washington University School of Medicine in St. Louis. At Washington University, he conducted research and taught human gross anatomy and histology. He received awards both for his research and teaching, including twice being awarded Professor of the Year by the senior class. During his tenure at Washington University, Dr. Menton served as the histology consultant for five editions of Stedman’s Medical Dictionary and was a guest lecturer in histology at Stanford University Medical School. He spent two summers studying an unusual wound-healing mechanism in sea cucumbers (a marine invertebrate) at Woods Hole Marine Biology Laboratory on Cape Cod in Massachusetts. Dr. Menton retired in the year 2000 as an Associate Professor Emeritus after 34 years on the faculty. Shortly after retirement, Dr. Menton joined Answers in Genesis as a speaker and researcher. He now travels and speaks for AiG throughout much of the U.S. as well as overseas, including recent events in Canada, the United Kingdom, Australia, Trinidad, Peru, and Turkey. He has also contributed numerous articles to Answers magazine and book chapters to The New Answers Book 2. Dr. Menton conducts special workshops by arrangement for school and church groups of all ages. In the workshops he employs photographs, anatomical models, and a special video microscope to cover a wide variety of topics on life science.”
Exploring History
Henry Stommel, an eminent oceanographer from Woods Hole Oceanographic Institute, envisioned the day that there would be a thousand swimming robots in the sea. His vision has been partially realized with the technology in Autonomous Underwater Vehicles (AUVs), computer-controlled systems operating under the water.
When you compare vehicles, some of them look like torpedoes, some of them look like stingrays, some of them look like things with flippers on them. So the breadth of that is pretty exciting, and what they can do.
They are designed with the intelligence to perform their tasks, identify problems, and adapt to different situations. AUVs can help protect our environment, as well as mitigate threats to our national security. And now, they are even being used to search for sunken history.
So, when you take AUV technology, you can see how the ships maneuvered, where the canon balls landed, where all the ship debris scattered as they blew up. That gives you greater insight as to the decisions that were made on those significant days.
Autonomous Underwater Vehicles can be equipped with sophisticated sensing devices. These sensors can measure different ocean characteristics; others can provide images of objects under the water or even buried below the ocean bottom. Since visibility under the sea is usually poor, sound - or SONAR - is used to create these acoustic pictures.
Side-Scan Sonar can produce very realistic imagery of objects and the seafloor. As the ping, or sound wave, travels underwater, it will reflect off objects such as sunken ships. The sonar distinguishes between these objects and creates dark or light regions that make up the astonishingly clear images we are able see today.
Since the 1990's, the Office of Naval Research has been investing in AUVs and their advanced sensors to help search for mines. Now, marine archeologists are able to use this amazing technology and put it to use exploring sunken history.
Over 2,000 shipwrecks can be found in the waters off Rhode Island, which has more shipwrecks than any other state per square mile. These shipwrecks include British frigates intentionally burned and sunk during the Revolutionary War in 1778 to avoid capture by a French fleet.
Four of these shipwreck sites, including the HMS Cerberus and HMS Lark, were explored using AUV technology. Several new discoveries are being made with these advanced remote sensing technologies, as they help marine archeologists answer important questions about our history.
A benefit of AUV exploration, and one that is of critical importance in exploring sunken ships, is the non-invasive nature of the technology. AUV missions will not disturb these delicate sites in any physical way.
Not only can AUVs help marine archeologists, but they are also being used in coastal surveys, fisheries research, and ocean exploration. Through these demonstrations, we can really grow the pull for this technology and basically increase access to the sea. Everything good will follow from that.
Perhaps a thousand swimming robots in the sea is closer than we think.
