(Phys.org)—It has been a desire, if not a dream for many throughout human history, to create a device that allows for seeing through walls (ala Superman), inside the human body or through a shield so that the enemy can ...
If you have ever turned on your car's high beams while driving through fog, you've seen glare in action. As the extra light reflects off the fog, it becomes even more difficult to see what lies ahead. In compelling new research, ...
