Veterans Week: Fighting in the Electromagnetic Spectrum (November 13, 2024 12:00pm)

Event Begins: Wednesday, November 13, 2024 12:00pm
Location: Off Campus Location
Organized By: Veteran and Military Services


Naval warfare was confined for centuries to surface combat and undersea clashes. In the 20th century, aerial warfare became the third domain, and shortly thereafter, the electromagnetic spectrum also appeared. When navies began to make use of the airwaves, they soon discovered those waves could also be exploited as a source of information about the opposing force, beginning the discipline of electronic intelligence (ELINT). Furthermore, navies learned the value of interrupting or corrupting the enemy’s communication signals that were transmitted in the “ether," leading to the method of fighting termed electronic warfare (EW).

In this book, Wildenberg cuts through the secrecy about this understandably mysterious domain of combat. He offers details on aircraft and methods and provides a layman’s set of definitions of terms. Wildenberg shares lessons learned from World War II skirmishes as well as clashes in the Korean and Vietnam Wars, while providing the audience with a foundational understanding of this complex form of combat in all its forms.

This book discloses rarely covered concepts and methods that will shape future conflict among great powers.

About the Author:
Thomas Wildenberg is an independent historian and scholar with special interests in aviators, naval aviation, and technological innovation in the military. He has written extensively about the U.S. Navy during the interwar period. His articles have appeared in several scholarly journals, including the Journal of Military History, American Neptune, Air Power History, and U.S. Naval Institute Proceedings. He is the author of several books on naval history covering such varied topics as replenishment at sea, the development of dive bombing, and the history of the torpedo in the U.S. Navy. His interest in the personalities of innovators has led to books on Admiral Joseph Mason Reeves, Billy Mitchel, Charles Stark Draper, and Howard Hughes. His latest work, “The Origins of Aegis,” has just been released by the Naval Institute Press.

Mr. Wildenberg served as a Ramsey Fellow at the National Air and Space Museum from 1999-2000. He is a recipient of the Arthur W. Radford Award for Excellence in Naval Aviation History (2012), the Surface Navy Association Literary Award (2005), and two John Laymen Awards from the North American Society for Oceanic History for best naval history (2013) and best biography (2003). He received the Air Force Historical Foundation's award for the best article in the 2009 volume of Air Power History, was awarded an honorable mention in the Ernest J. Eller Prize in Naval History (1994), and received the Edward S. Miller Naval War College Research Fellowship (1998).

good boy, Mitten Bakery ????

"Who's a good boy?" you petting your cute dog next to me. I asked "Oh me?". You said, "Well if I get two good boys out of it ya!" - I didn't get ur #!

Smokin Hot at Smoker Dad

I Saw U at the Sunset Tavern at the Smoker Dad release show. You were wearing a tight jean skirt, and you told me I had a timeless beauty. Same, girl.

Barrettes at Hop Vine 10.28

I stared, we waved! I looked up how to sign “ur super cute” but was too shy. I like your hair, sweater, how you cover your mouth when you laugh!

I saw u x2 @ SBP

BV Lincoln SQ: 3:30, Sunday. You were exiting. Tall, dark, a beautiful print coat, thin glasses, I said I liked your outfit. You are art in motion.

Fellow Magnetic Fields Fans

We sat in the balcony turret the first night of 69 Love Songs. Thanks for singing along with me! Hope you got to come back for Papa was a Rodeo.

From Coulomb’s force to magnetic force and experiments that show magnetic force parallel to current

Abstract: The Lorentz force law is fundamental for electromagnetism. However, it is known long ago that the Lorentz forces between two current elements do not respect the Newton’s third law. This seemingly harmless flaw had never been corrected. In physical sciences a discrepancy often hides in it new understanding or unexpected breakthrough. For solving this...

Erosion protection of Tokamak and magnetic force on single charge

Abstract: The walls of Tokamaks are heavily eroded by plasma which suggests that a mysterious force pushes the plasma to the wall. We have theoretically discovered this force and named it extra-force. This force appears only on single charges but not on current carrying wire, which is why the Lorentz force law does not contain...

CMMB (Carboxylate Modified Magnetic Bead) -based isopropanol gradient peptide fractionation (CIF) enables rapid and robust off-line peptide mixture fractionation in bottom-up proteomics [Research]

Deep proteome coverage in bottom-up proteomics requires peptide-level fractionation to simplify the complex peptide mixture before analysis by tandem mass spectrometry. By decreasing the number of co-eluting precursor peptide ions, fractionation effectively reduces the complexity of the sample leading to higher sample coverage and reduced bias towards high abundance precursors that are preferentially identified in data-dependent acquisition strategies. To achieve this goal, we report a bead-based off-line peptide fractionation method termed CIF or Carboxylate modified magnetic bead-based isopropanol gradient peptide fractionation. CIF is an extension of the SP3 (single-pot solid-phase-enhanced sample preparation) strategy and provides an effective but complementary approach to other commonly used fractionation methods including strong cation exchange (SCX) and reversed phase (RP)-based chromatography. We demonstrate that CIF is an effective offline separation strategy capable of increasing the depth of peptide analyte coverage both when used alone or as a second dimension of peptide fractionation in conjunction with high pH RP. These features make it ideally suited for a wide range of proteomic applications including the affinity purification of low abundance bait proteins.

Voyager 2's Historic Flyby of Uranus Exposes Rare Magnetic Distortion

A new analysis of Voyager 2’s flyby of Uranus in 1986 reveals a unique magnetic anomaly caused by a rare solar wind event. Scientists from NASA's Jet Propulsion Laboratory and Caltech found that the solar wind’s impact on Uranus’s magnetosphere was a unique occurrence, influencing measurements of the planet’s magnetic field. The study also suggests that the planet’s outer moons lie within its magnetosphere, potentially aiding future probes in identifying subsurface oceans on these moons.
