The National Institute of Standards and Technology (NIST), known between 1901 and 1988 as the National Bureau of Standards (NBS), is a measurement standards laboratory, also known as a National Metrological Institute (NMI), which is a non-regulatory agency of the United States Department of Commerce. The institute's official mission is to:
NIST had an operating budget for fiscal year 2007 (October 1, 2006-September 30, 2007) of about $843.3 million. NIST's 2009 budget was $992 million, and it also received $610 million as part of the American Recovery and Reinvestment Act. NIST employs about 2,900 scientists, engineers, technicians, and support and administrative personnel. About 1,800 NIST associates (guest researchers and engineers from American companies and foreign countries) complement the staff. In addition, NIST partners with 1,400 manufacturing specialists and staff at nearly 350 affiliated centers around the country. NIST publishes the Handbook 44 that provides the "Specifications, tolerances, and other technical requirements for weighing and measuring devices".
Cumulo- means "heap" or "pile" in Latin.Cumulus clouds are often described as "puffy", "cotton-like" or "fluffy" in appearance, and have flat bases. Cumulus clouds, being low-level clouds, are generally less than 1,000 m (3,300 ft) in altitude unless they are the more vertical cumulus congestus form. Cumulus clouds may appear by themselves, in lines, or in clusters.
Cumulus clouds are often precursors of other types of cloud, such as cumulonimbus, when influenced by weather factors such as instability, moisture, and temperature gradient. Normally, cumulus clouds produce little or no precipitation, but they can grow into the precipitation-bearing congestus or cumulonimbus clouds. Cumulus clouds can be formed from water vapor, supercooled water droplets, or ice crystals, depending upon the ambient temperature. They come in many distinct subforms, and generally cool the earth by reflecting the incoming solar radiation. Cumulus clouds are part of the larger category of free-convective cumuliform clouds, which include cumulonimbus clouds. The latter genus-type is sometimes categorized separately as cumulonimbiform due to its more complex structure that often includes a cirriform or anvil top. There are also cumuliform clouds of limited convection that comprise stratocumulus (low-étage), altocumulus (middle-étage) and cirrocumulus. (high-étage). These last three genus-types are sometimes classified separately as stratocumuliform.
Uncertainty is the situation which involves imperfect and / or unknown information. In other words it is a term used in subtly different ways in a number of fields, including insurance, philosophy, physics, statistics, economics, finance, psychology, sociology, engineering, metrology, and information science. It applies to predictions of future events, to physical measurements that are already made, or to the unknown. Uncertainty arises in partially observable and/or stochastic environments, as well as due to ignorance and/or indolence.
Although the terms are used in various ways among the general public, many specialists in decision theory, statistics and other quantitative fields have defined uncertainty, risk, and their measurement as:

This video is from AE911Truth.org. "Truth is where our healing lies." NIST Employee Speaks Out on WTC-7 Cover-up A former employee of the National Institute of Standards and Technology (NIST) has stepped forward and criticized the government agency for ignoring the scientific errors found in its report on the collapse of World Trade Center Building 7 (WTC 7) during the September 11, 2001, attacks. "Awareness is growing of the disconnect between the NIST WTC reports and logical reasoning. The level of interest in '15 years later' is a good example. Due to the nature of communication in today's world, that awareness may increase approximately exponentially. Why not NIST blow the whistle on itself now while there is still time? - Truth is where our healing lies." - Peter Michael Ketcham, form...
00:00 - About 19 seconds after first plane hit the North Tower at approx. 8:46:25 a.m. Filmed from school yard of the Independence School (P.S. 234), at Greenwich Street. Recording starts at 8:46:44 a.m. Time uncertainty was assigned by NIST with 1 second for each CUMULUS clip. 01:48 - First and loud "KNOCK" or "DUP" noise. Comes maybe from the damaged building structure, either from the impact zone or Hat Truss region. For further similar noises in the time span between the plane strikes, see video markings 02:43, 03:00, 03:55 - 04:08, 04:42, 06:28, 07:17, 07:26, 07:54, 08:12- 08:23, 09:10 - 09:12, 09:20, 09:25, 09:31, 09:47, 09:50. 11:22 - Second impact missed.

NEW! NIST 9/11 report EXPOSED-A former employee Speaks Out Published on Mar 13, 2017 In August of 2016, a former employee of the National Institute of Standards and Technology (NIST) began looking into the reports his agency had released years earlier on the collapse of the World Trade Center. What he found shook him to the core. In this poignant half-hour interview, Peter Michael Ketcham tells his story of discovering that the organization where he had worked for 14 years had deliberately suppressed the truth about the most pivotal event of the 21st century. Through his willingness to look openly at what he failed to see in front of him for 15 years, Mr. Ketcham inspires us to believe that we can all muster the courage to confront the truth — and, in so doing, finally heal the wounds o...

Daddy was always an honest man
He spoke with his heart and helped with his hands
There wasn't a stranger he didn't soon know
I watched him build bridges wherever he'd go
Daddy was a farmer, always out in the field
We never had money, but there was always a meal
He counted his blessings and the Bible he read
I'll never outgrow the words that he said
CHORUS:
If I possessed all the wealth in the world
It would not be enough to survive
When I look in the eyes of my children and wife
I can see I've been given the finer things in life
Now I'm a daddy with two little ones
The first a shy princess, then a curious son
Well, they never knew their Grandpa too well
But his message of love I'll continue to tell
(CHORUS)
