Be it enacted by the Senate and House of Representatives of the United States of America in Congress assembled, That the Secretary of Metric system. Commerce is hereby authorized to conduct a program of investigation, Study. research, and survey to determine the impact of increasing worldwide use of the metric system on the United States; to appraise the desir- ability and practicability of increasing the use of metric weights and measures in the United States; to study the feasibility of retaining and promoting by international use of dimensional and other engi- neering standards based on the customary measurement units of the United States; and to evaluate the costs and benefits of alternative courses of action which may be feasible for the United States. Sec. 2. In carrying out the program described in the first section of Investigation this Act, the Secretary, among other things, shall and appraisal requirements. (1) investigate and appraise the advantages and disadvantages to the United States in international trade and commerce, and in military and other areas of international relations, of the increased use of an internationally standardized system of weights and measures; (2) appraise economic and military advantages and disad- vantages of the increased use of the metric system in the United States or of the increased use of such system in specific fields and the impact of such increased use upon those affected; (3) conduct extensive comparative studies of the systems of weights and measures used in educational, engineering, manu- facturing, commercial, public, and scientific areas, and the rela- tive advantages and disadvantages, and degree of standardization of each in its respective field; (4) investigate and appraise the possible practical difficulties which might be encountered in accomplishing the increased use of the metric system of weights and measures generally or in specific fields or areas in the United States; (5) permit appropriate participation by representatives of United States industry, science, engineering, and labor, and their associations, in the planning and conduct of the program author- ized by the first section of this Act, and in the evaluation of the information secured under such program; and (6) consult and cooperate with other government agencies, Federal, State, and local, and, to the extent practicable, with foreign governments and international organizations.

Sec. 4. The Secretary shall submit to the Congress such interim Report to reports as he deems desirable, and within three years after the date of Congress. the enactment of this Act, a full and complete report of the findings made under the program authorized by this Act, together with such recommendations as he considers to be appropriate and in the best interests of the United States. Funds. Sec. 5. From funds previously appropriated to the Department of Commerce, the Secretary is authorized to utilize such appropriated sums as are necessary, but not to exceed $500,000, to carry out the pur- poses of this Act for the first year of the program.

S/N 0303 0884 U.S. DEPARTMENT OF COMMERCE Office of the Secretary Washington, D.C. 20230 THE HONORABLE PRESIDENT OF THE SENATE THE HONORABLE SPEAKER OF THE HOUSE OF REPRESENTATIVES SIRS: I have the honor to transmit to you the Report on the U.S. Metric Study, which was conducted by the National Bureau of Standards of the Department of Commerce. Thousands of individuals, firms and organized groups, representative of our society, participated in the Study. After weighing the extensive evidence pre- sented by these participants, this report concludes that the United States should change to the metric system through a coordinated national program. I agree with this conclusion, and therefore recommend — That the United States change to the International Metric System delib- erately and carefully; — That this be done through a coordinated national program; — That the Congress assign the responsibility for guiding the change, and anticipating the kinds of special problems described in the report, to a central coordinating body responsive to all sectors of our society; — That within this guiding framework, detailed plans and timetables be worked out by these sectors themselves; — That early priority be given to educating every American schoolchild and the public at large to think in metric terms; — That immediate steps be taken by the Congress to foster U.S. participa- tion in international standards activities; — That in order to encourage efficiency and minimize the overall costs to society, the general rule should be that any changeover costs shall "lie where they fall"; — That the Congress, after deciding on a plan for the nation, establish a target date ten years ahead, by which time the U.S. will have become predominantly, though not exclusively, metric; — That there be a firm government commitment to this goal. The Department of Commerce stands ready to provide whatever further assistance the Congress may require in working out a national plan and putting it into effect. Respectfully submitted, Maurice H. Stans Secretary of Commerce U.S. DEPARTMENT OF COMMERCE National Bureau of Standards Washington, D.C. 20234 OFFICE OF THE DIRECTOR The Honorable Maurice H. Stans Secretary of Commerce Dear Mr. Secretary: I have the honor to transmit to you the report on the U.S. Metric Study, undertaken by the National Bureau of Standards at your request, pursuant to Public Law 90-472. This report embodies our analysis of the alternatives realis- tically open to the United States and the choice we recommend on the basis of the evidence marshalled during the Study. I am convinced that after nearly two hundred years of national debate on this issue, the time has come for a national decision on a positive course of action. The questions posed by the Congress do not lend themselves to a clear-cut analysis in terms of dollars and cents, although we have discussed the question of costs and benefits as objectively as we could. Neither are the questions to be answered by evaluating the scientific merits of different measurement systems in the abstract, even though American scientists, like those of other nations, com- monly prefer the metric system for their work. Accordingly, our Metric Study Group based their work primarily on the informed views of citizens in every walk of life, considering not only their experiences but their apprehensions, their hopes for the future and the realities of current problems. We have done our best to give everyone an opportunity to express his or her views. Just as numbers are the language of mathematics, measurement language permits people to communicate with one another in quantitative terms. The na- tion's measurement system must be not only accurate and precise; it must be useful. This perspective is reflected in the Department's goal for the National Bureau of Standards: to strengthen the nation's science and technology and to foster their useful application in the public interest. From this vantage point — how the measurement system can best serve the future needs of America as we enter our third century of progress — we have examined the matter of metric conversion. Sincerely, Lewis M. Branscomb, Director National Bureau of Standards V I FROM THE FIRST METRIC STUDY Weights and Measures may be ranked among the neces- saries of life to every individual of human society. They enter into the economical arrangements and daily con- cerns of every family. They are necessary to every occu- pation of human industry; to the distribution and security of every species of property; to every transaction of trade and commerce; to the labors of the husbandman; to the ingenuity of the artificer; to the studies of the philosopher; to the researches of the antiquarian; to the navigation of the mariner, and the marches of the soldier; to all the ex- changes of peace, and all the operations of war.

Thinking about the Unthinkable Of all the unexamined assumptions and criteria upon which we base and gauge our daily lives as human beings on planet Earth, by far the greatest and most profoundly unquestioned is the instrument and institution known as the Gregorian Calendar. A calendar, any calendar, is commonly understood as a system for dividing time over extended periods. A day is the base unit of a calendar, and the solar year is the base extended period. The length of the solar year is currently reckoned at 365.242199 days. The Gregorian calendar divides this duration into twelve uneven months – four months of 30 days, seven of 31 days, and one of 28 days.

  • Dave Consiglio, April 18, 2016 How Can Our Calendar Be Re-Designed to Be More Convenient and Scientific?
    Dave Consiglio, April 18, 2016 How can our calendar be re-designed to be more convenient and scientific? Ah, decimal time. In the time system proposed (primarily) by the French, we would have had 1000 seconds in an hour, 100 minutes in an hour, and 10 hours in a day, 10 days in a week, and 10 months in a year. But it could have done nothing to change the number of days in a year. That's because the rotational period of the Earth and the revolutionary period of the Earth are completely unrelated. In other words, the length of a day and the length of a year aren't on speaking terms. Each year really does last 365.24 (roughly) days, regardless of how you divide those days into hours and minutes. So, at the end of a year, you have about 1/4th of a day to add to catch up. This is awkward, so the current calendar does the only logical thing: add a day every 4th year, and then make corrections every century or so. We can divide the day however we want, but we would have ended up with the same problem of leap day. So, our perfect decimal calendar would still need 365 days each year for 3 years, and then 366 for the fourth. These aren't very "decimally" numbers! Now, you could go about adding seconds, or even minutes, instead, but this just gets more and more confusing. Once every 4 years is simple enough, and it solves the problem with enough accuracy that adjustments are only required every century or so.

  • Red Overtone Moon Year
    Resonant Truth presents NATURAL TIME A 13 Moon Calendar inspired by Mayan cycles Red Overtone Moon Year July 26, 2010 - July 24, 2011 July 26, 2010 - July 24, 2011 HowRED Can OVERTONE I Best Empower MOON Myself Red Overtone Moon is the fifth year in a cycle of 13. Four years ago, we began a new 13-year ‘wavespell’ that celebrates the energy of Red Moon. A wavespell is any cycle of 13, be it days, moons or years. As its name indicates, a wavespell is a spell of time that builds and breaks in a wave formation. There are 13 stages in the growth of the wave and its dissolution, each offering a specific teaching for us as guidance in our own transformation. In the Overtone time the wave begins its ascent in earnest. For the past four years we have been making preparations, in a sense, laying a foundation for the accomplishment to come. We have been held in check, a little, from taking off with our dreams, but only in order to be truly ready when they come closer to reality. The Overtone energy is described as an act of empowerment; we are given the life force to rise. Think again of the ocean and the moment when the swell that began in the depths pushes above the surface, starting a visible arc towards the sky. We are in that magic transit, when we not only feel ourselves uplifted but see the reflection in our lives. The journey to the wave’s peak is very much a movement towards the sun itself and the enlightenment it holds, so we will feel some pleasure and ease this year, that we are steadily climbing closer to the heavens, and towards the divinity that lives there.

    Topic 3: Kinematics – Displacement, Velocity, Acceleration, 1- and 2- Dimensional Motion Source: Conceptual Physics textbook (Chapter 2 - second edition, laboratory book and concept-development practice book; CPO physics textbook and laboratory book Types of Materials: Textbooks, laboratory manuals, demonstrations, worksheets and activities Building on: With beginning concepts of vectors and measurements, the study of motion will give the lead-in to dynamics, the cause of motion that allows the student to see a logical building of mechanics. Topic one activities have introduced displacement and velocity and will now be enhanced. The instructor should now define displacement, velocity and acceleration. A new displacement activity will use a worksheet and speed vs. velocity will use a worksheet and several additional activities. One-dimensional motion will be studied with labs and two-dimensional motion will be briefly presented but not so in depth that it takes too much time to cut out time for other topics. Finally, an acceleration activity and worksheet will be presented. Leading to: Once the study of motion is explored in more detail, the teacher will then ask, “What causes motion or the change in motion?” that is presented through activities to begin dynamics, the study of the cause of motion. Links to Physics: Understanding of motion is fundamental to mechanics including constant or accelerated motion of cars to electrons. Other topics will also require the introduction of motion. Examples include wave motion (as in sound and light), electricity and magnetism (movement of force fields) and celestial movement within the heavens. Links to Chemistry: Displacement and 1- and 2-dimensional motion may be used in showing conceptual representations of atoms and molecules during reactions.

  • The Significance of the Millennium
    The Significance of the Millennium The millennium has no natural terrestrial, sidereal, or cosmic basis or importance. But the last years of the twentieth century are the first in human history in which there has been a worldwide recognition that a millennium measured by a universally accepted calendar is about to end and a new one begin. LEE LOEVINGER arly in 1996 the Rainbow Room in New York and the Savoy in London announced their facilities were fully Ebooked and they could accept only waiting list reser- vations for the night of December 31, 1999. Other popular places for New Year's Eve celebrations have similarly been receiving requests for reservations more than three years in advance of the beginning of the year 2000. A cruise-line fleet of sailing ships has been fully chartered as of September 1996, and another cruise line is taking reservations (with deposits) for "Turn of the Century" cruises. Such lengthy anticipation is most extraordinary. There are several reasons for such interest; but it is at least partially attributable to our addiction to the decimal (or base ten) sys- SKEPTICAL INQUIRER January/February 1997 31 tern of numeration which leads us to be unusually attentive to to the millennium. The imminence of a new millennium has occasions that mark a new decimal date, such as the end of a stimulated Professor Harold Bloom of Yale to explicitly decade.

  • EN Perceptions of Time. Cultures and Calendars DRAFT
    Perceptions of Time: Cultures and Calendars Envisioning the idea of communities of practice between students and also teachers to share resources, best practices, ideas, and building wider networks, eTwinning can help students in different parts of the world to do this activity together (through a blog for example). It could allow students to experience different perceptions of time, different calendars (example of lunar or Chinese) and discuss with students from 1 diverse contexts their perspectives of time and its cultural relevance. In addition, it allows teachers and practitioners from different countries to be able to work together and develop projects amongst them. Description In this activity, students will explore human perception of time through the exploration of different calendars. Using philosophical questioning regarding the idea of time, and its measurement, they will be encouraged to research and compare the solar (Gregorian) and the lunar (Hijri) calendars, as well as other calendars used by different traditions and civilizations. In addition, students are likely be challenged to use mathematical skills and problem solving to convert dates using these different calendars, and lead to discuss the notion and idea of time in theoretical terms, as well as its contemporary relevance. Global citizenship competences addressed capacity to examine global issues appreciate different perspectives & world views positive interactions with people who are different analytical & critical thinking skills communication & co-operation skills Global citizenship content Defined simply, pluralism is an ethic of respect for diversity. Whereas diversity is a fact, pluralism is a choice. Pluralism results from the daily decisions taken by state institutions, by civil society actors and associations and by individuals to recognize and value human differences.

  • Tens and Tenths: Decimalising Calendar and Angle
    Tens and tenths: decimalising calendar and angle Lachlan Marnoch, 2014 & 2018 Humans tend to think in multiples of ten. Perhaps it’s because we have ten fingers. Most major number systems throughout history, from the Roman to the Hindu-Arabic, are based around the number 10. Thus, it makes sense for the units we use in everyday life - whether they are used to represent currency, length, or time - to employ the number 10 as their base. We already count in tens; why not extend this to all measurements? This essay will explore the advantages and disadvantages of purely decimal systems, while also proposing a set of alternate, decimalised units for some quantities. Non-decimal units of measurement are still used fairly widely, despite being phased out in most regions. The Imperial system, for example, is still used partially in the United Kingdom; a modified set known as US customary units, are kept alive in the United States of America. Under these systems, there are 12 inches in a foot, 3 feet in a yard, 22 yards in a chain, 10 chains in a furlong, 8 furlongs in a mile, and 3 miles in a league. This means that there are 5,280 feet in a mile. The difficulty in remembering so many different units, and their irregular ratios, puts anyone trying to use the Imperial system at quite a disadvantage. The metric system, on the other hand, which is heavily decimalised, has one hundred centimetres per metre (equivalent to about 3.28 feet), one thousand metres per kilometre, one thousand kilometres per megametre, and so on.
