Arleigh Burke Class DDG 108 Named for Wayne Meyer, a former ATI instructor.

An Arleigh Burke Class DDG 108 was named for Wayne Meyer, a former ATI instructor. Rear Adm. Wayne E. Meyer is also known as the father of AEGIS. After he retired from the Navy in 1985 he taught several professional development classes on Combat Systems Engineering for ATI based on his many years of systems engineering experience with the AEGIS combat System. Wayne E. Meyer passed away on Sept 1, 2009, and did not get to see this ship's commissioning, which bears his name, but his legend as 'father of Aegis" is well known. Click here to read more

Acoustic Handbook and Training Reference Guide

The Environmental Acoustical Handbook provides useful reference information for Underwater Acoustics. The handbook was published under government contract in 1991 by Planning Systems Incorporated. The information is still useful today. ATIcourses republishes this information to provide useful information to the acoustics and sonar community.

    International System of Units

    The International System of Units (SI) established in 1960 by the General Conference of Weights and Measures under the Treaty of the Meter is based upon: the meter (in) for length; the kilogram (kg) for mass; the second (s) for time; the Kelvin (K) for temperature; the ampere (A) for electrical current; and the candela (ed) for luminous intensity.

    AU other units of SI are derived from these base units by assigning the value unity to the proportionality constants in the defining equations, e.g.,

    I Pa = I N/m2 = (I kg - in / seC2) / M2 = I kg - M-1 . sec-2.

    Taking 1/100 of the meter as the unit for length and 1/1000 of the kilogram as the unit for mass gives rise similarly to the cgs system, often used in physics and chemistry.
