10 Recent Scientifically Solved Mysteries

Since the beginning of modern science we have been solving the great mysteries around us. Because of recent advances in science and technology
we now have the ability to unravel some unknowns like never before. 

The Ancient Theater of Epidaurus near Athens Greece was constructed in the late 4th century BC and is one of the best preserved ancient theaters. Even in ancient times, the theater was considered to have great acoustics. The actors can be perfectly heard by all 15,000 spectators without amplification. To demonstrate the theaters great acoustics tour guides have their groups scattered in the stands and then show them how faint sounds can be heard at center-stage. How this sound quality was achieved has been the source of academic and amateur speculation for many years. One of the theories suggested that prevailing winds were carrying the sounds. It turns out that that answer is in the seats. In 2007 researchers at the Georgia Institute of Technology have discovered that the limestone material of the seats provide a filtering effect suppressing low frequencies of voices, thus minimizing background crowd noise so the seats act as natural acoustic traps. It is still unknown whether the acoustic properties are the result of an accident or the product of advanced design.

Reading through these I have a feeling that even though these mysteries are scientifically proven like the face on mars, people will still cling to delusional beliefs that it's just a cover-up to keep the truth from coming out. One of those strange quirks of human nature I guess.

Ancient engineers and inventors were in a situation where there was no 'status quo' or solidly set assumptions to prevent the creative process. Some good ideas come from trial and error, and usually the best ones become known due to the error. I've also found that technological breakthroughs happen not from the constant improvement of the leading technology, but the stepping back and looking at something in the past and making it better with currant resources.
