The Great Lakes contain enough fresh water to cover the land area of the entire United States under 3 meters of water.
We collect 15 video presentations about Great Lake water safety and sustainability prepared by the 8 Great Lake border state colleges and universities and their national and international partners in Canada.
When the wicked problems of peace and economic inequality cannot be solved, political leaders, and the battalions of servile administrative muckety-mucks who report to them, resort to fear-mongering about an imagined problem to be solved centuries hence assuming every other nation agrees on remedies of its anthropogenic origin. We would not draw attention to it were it not that large tranches of the global academic community are in on the grift costing hundreds of billions in square-footage for research and teaching hopelessness to our children and hatred of climate change deniers.
Before the internet is scrubbed of information contrary to climate change mania, we recommend a few titles:

Abstract: Quantum computing is an emerging field that can revolutionize our ability to solve problems and enable breakthroughs in many areas including optimization, machine learning, chemistry, and drug design. With the increasing computational power of quantum computers and the proliferation of quantum development kits, the demand for a skilled workforce in quantum computing increases significantly. The theory of quantum computing lies at the crossroads of quantum physics, mathematics, and computer science. The field of quantum computing has matured and can now be explored by all students. While today, quantum computers and simulators are readily accessible and programmable over the internet, quantum computing education is just ramping up.
This paper describes our experiences in organizing and delivering quantum computing workshops for high-school students with little or no experience in the abovementioned fields. We introduce students to the world of quantum computing in innovative ways, such as newly designed “unplugged” activities for teaching basic quantum computing concepts. Overall, we take a programmatic approach and introduce students to the IBM Q Experience using Qiskit and Jupyter notebooks. Our experiences and findings suggest that basic quantum computing concepts are palatable for high-school students, and-due to significant differences between classical and quantum computing-early exposure to quantum computing is a valuable addition to the set of problem-solving and computing skills that high-schoolers obtain before entering university.
Dirac Bra-Ket notation, also known simply as bra-ket notation, is a standard mathematical notation used extensively in quantum mechanics and quantum computing. It was introduced by Paul Dirac and provides a convenient and powerful framework for describing quantum states and their evolution. Here are several ways in which Dirac Bra-Ket notation is important in quantum computing:
Representation of Quantum States:
Kets (|ψ⟩): Quantum states are typically represented as kets, denoted by |ψ⟩. This notation simplifies the representation of complex vectors in a Hilbert space.
Bras (⟨ψ|): The corresponding dual vectors, or bras, are denoted by ⟨ψ|. These are the complex conjugate transpose of the kets.
Inner Product:
The inner product of two states |ψ⟩ and |φ⟩ is written as ⟨ψ|φ⟩. This notation succinctly captures the concept of the probability amplitude, which is fundamental to quantum mechanics and quantum computing.
Outer Product:
The outer product, written as |ψ⟩⟨φ|, represents a linear operator that can be used to construct projection operators and density matrices, which are crucial in quantum algorithms and quantum information theory.
Operators and Measurements:
Quantum operators, such as Hamiltonians and measurement operators, can be conveniently expressed using bra-ket notation. For example, an operator A^\hat{A}A^ acting on a state |ψ⟩ can be written as A^∣ψ⟩\hat{A}|ψ⟩A^∣ψ⟩.
Measurement probabilities are often expressed in terms of bras and kets, e.g., the probability of measuring a state |ψ⟩ in the basis state |φ⟩ is |⟨φ|ψ⟩|².
Tensor Products:
In quantum computing, systems are often composed of multiple qubits, which are represented by tensor products of individual qubit states. Bra-ket notation elegantly handles these tensor products, e.g., |ψ⟩⊗|φ⟩.
Quantum Gates and Circuits:
Quantum gates, which perform operations on qubits, can be represented using unitary operators in bra-ket notation. For example, the action of a gate U on a qubit state |ψ⟩ is written as U|ψ⟩.
Simplifying Complex Expressions:
Bra-ket notation simplifies the manipulation of complex expressions involving quantum states and operators, making it easier to derive results and understand the behavior of quantum systems.
Formalism for Quantum Algorithms:
Many quantum algorithms, such as the Quantum Fourier Transform (QFT) and Grover’s search algorithm, are conveniently expressed and analyzed using bra-ket notation, providing clarity and insight into their functioning.
In summary, Dirac Bra-Ket notation is essential in quantum computing for its ability to provide a clear and concise way to describe and manipulate quantum states, operators, and the evolution of quantum systems. It is a powerful tool that underpins much of the theory and practice in the field.

In these clips — selected from Canadian Parliamentary debate in 2013 — we observe three points of view about Incorporation by reference(IBR); a legislative drafting technique that is the act of including a second document within a main document by referencing the second document.
This technique makes an entire second (or referenced) document a part of the main document. The consensus documents in which we advocate #TotalCostofOwnership concepts are incorporated by reference into legislation dealing with safety and sustainability at all levels of government. This practice — which many consider a public-private partnership — is a more effective way of driving best practices for technology, and the management of technology, into regulated industries.
Parent legislation — such as the Higher Education Act of 1965, the Clean Air Act and the Energy Policy Act – almost always require intermediary bureaucracies to administer the specifics required to accomplish the broad goals of the legislation. With the gathering pace of governments everywhere expanding their influence over larger parts of the technologies at the foundation of national economies; business and technology standards are needed to secure that influence. These standards require competency in the application of political, technical and financial concepts; competencies that can only be afforded by incumbent interests who build the cost of their advocacy into the price of the product or service they sell to our industry. Arguably, the expansion of government is a reflection of the success of incumbents in business and technical standards; particularly in the compliance and conformity industries.
About two years ago, the US debate on incorporation by reference has been taken to a new level with the recent statement released by the American Bar Association (ABA):
The incorporation by reference policy dilemma has profound implications for how we safely and economically design, operate and maintain our “cities-within-cities” in a sustainable manner but, admittedly, the results are only visible in hindsight over a time horizon that often exceed the tenure of a typical college or university president.
A recent development — supporting the claims of ANSI and its accredited standards developers — is noteworthy:
The National Institute for Standards and Technology (NIST) manages a website — Standards.GOV — that is a single access point for consensus standards incorporated by reference into the Code of Federal Regulations: Standards Incorporated by Reference Database. Note that this database does not include specific reference to safety and sustainability codes which are developed by standards setting organizations (such as NFPA, ICC, IEEE, ASHRAE and others) and usually incorporated by reference into individual state public safety and technology legislation.

Two universes mosey down the street
Connected by love and a leash and nothing else.
Mostly I look at lamplight through the leaves
While he mooches along with tail up and snout down,
Getting a secret knowledge through the nose
Almost entirely hidden from my sight.
We stand while he’s enraptured by a bush
Till I can’t stand our standing any longer
And haul on the leash to bring him away.
He lives in the moment, which is good for him,
But when I see a stone wall, I think of Greece,
The sort of place he’d have a lot to say about—
The sniffable pots and broken statues,
The seas, the Ionic evenings all in a row.
But he just gives a yelp and comes running over
To smell my palm, and what can I do but
Smile and bend down to give him a hello?
