Eleventh Annual Conference Chicago, Illinois 2005 August 18 – 21 John F
North American Sundial Society - Eleventh Annual Conference Chicago, Illinois 2005 August 18 – 21 John F. Schilke Who would not enjoy the mystique and appeal of free copies of Proceedings [of the] ISAMA CTI 2004, Chicago, that huge city on the shore of Lake Michigan? produced for a symposium on mathematics and design The architectural variety has to be seen to be held at DePaul. Among the door prize winners were appreciated. True, the weather was hot and sticky at Dwight Carpenter (several things, including a peg dial the first, but it soon settled into very pleasant summer and dial coins), Donn McNealy (Plymouth equatorial days and nights. DePaul University CTI Center sundial), Carl Schneider (a copy of Mike Cowham’s A provided a very comfortable setting for the thirty-four Dial in Your Poke), Dean Conners (A. P. Herbert’s people who attended the sessions. Fourteen wives and Sundials Old and New). A copy of Frank Cousins’ one care-giver, all hailing from 13 states and a total of Sundials became Walter Sanford’s prize, and Jacque 13 from Argentina, Canada, Germany, Taiwan, and the Olin and Karl Schneider each received a copy of Simon United Kingdom. During the conference several wives Wheaton-Smith’s Illustrating Shadows. took tours of Chicago and of the Chicago Art Museum with its special exhibition on Toulouse-Lautrec. Roger Bailey then showed how to program the programmable scientific calculator included in each registration packet. In doing so, he provided solutions to some of the equations useful in creating dials. Most actually got them to work! After a continental breakfast on Friday we boarded the bus to visit first the Museum of Science and Industry to see dials in their collection, including a fine example of a first-century (AD) dial, adjudged to be a slight variant of a hemisphaerium. -

Requiring no previous knowledge of linguistics, languages, or computing, these puzzles can be solved by analytic reasoning alone, and serve as a fun introduction to a field to which many high school students have never been introduced. Winners of NACLO are eligible to compete in the International Linguistics Olympiad, one of twelve international high school science Olympiads. Contact [email protected] What’s New in 2021? We have released an addendum detailing our COVID-19 contingency plans. It will continue to be updated throughout the months leading up to the competition. University sites will also be updating their NACLO websites to reflect the situation on their campuses. Contest in Canada The Anglophone contest in Canada takes place jointly with the contest in the United States. As of the writing of this version of the handbook, the dates for the 2021 Francophone contest in Canada have not been announced. -

However, even today, the world is yet to see clear signs of an end to the COVID-19 pandemic. Amidst such a situation, it would be very difficult to hold such a large-scale conference hosting attendees from all over the world, while preventing the spread of infection at the same time. In addition, some member cities outside of Japan have mentioned to the Secretariat that they are unlikely to be able to travel to Hiroshima to attend the General Conference due to financial constraints their cities are facing―reallocating and securing budget for medical support and economic recovery, while confronting decrease in tax revenues. -
1 Science Olympiad Alumni Where Are They Now? Stories of Scientific
Science Olympiad Alumni Where Are They Now? Stories of Scientific Achievement and Inspiration To celebrate the 20th anniversary of national competition in 2004, Science Olympiad began an effort to track down its most illustrious alumni. We were specifically interested to discover if Science Olympiad had an impact on the choice of a career in science or technology. Of the hundreds of respondents, more than 80% answered with a resounding “Yes!” Kathleen Markiewicz Teacher, Boston Public Schools Competed from 1998 to 2000 “It solidified my love for science. I enjoyed getting to learn about many areas of science in Science Olympiad, and I continue to be interested in lots of science disciplines. In particular, Science Olympiad showed me that I love chemistry and physics, which ultimately were my majors for my undergraduate degree. I am also coaching my own Science Olympiad team at the Boston Latin School, and it’s a great way to come full circle. My fiancé, who I met while on the Grand Haven High School Science Olympiad team, is also helping me coach.” Rich Radke Assistant Professor, Department of Electrical, Computer and Systems Engineering Rensselaer Polytechnic Institute Competed in the early 1990s “I believe that Science Olympiad was very helpful in showing me that science could be interesting and fun, and that there were organizations that rewarded people for achievement in science and math,” said an 18-year-old Radke in 1993. Today, Radke is a celebrated researcher and the winner of the National Science Foundation’s Early Career Development Award for his work with networked cameras. -
Math Olympiad Hardness Scale (MOHS) Because Arguing About Problem Difficulty Is Fun :P
Math Olympiad Hardness Scale (MOHS) because arguing about problem difficulty is fun :P Evan Chen April 30, 2021 In this document I provide my personal ratings of difficulties of problems from selected recent contests. This involves defining (rather carefully) a rubric by which I evaluate difficulty. I call this the MOHS hardness scale (pronounced \moez"); I also go sometimes use the unit \M" (for \Mohs"). The scale proceeds in increments of 5M, with a lowest possible rating of 0M and a highest possible rating of 60M; but in practice few problems are rated higher than 50M, so it is better thought of as a scale from 0M to 50M, with a few “off-the-chart" ratings. 1 Warning §1.1 These ratings are subjective Despite everything that's written here, at the end of the day, these ratings are ultimately my personal opinion. I make no claim that these ratings are objective or that they represent some sort of absolute truth. For comedic value: Remark (Warranty statement). The ratings are provided \as is", without warranty of any kind, express or implied, including but not limited to the warranties of merchantability, fitness for a particular purpose, and noninfringement. In no event shall Evan be liable for any claim, damages or other liability, whether in an action of contract, tort or otherwise, arising from, out of, or in connection to, these ratings. §1.2 Suggested usage More important warning: excessive use of these ratings can hinder you. For example, if you end up choosing to not seriously attempt certain problems because their rating is 40M or higher, then you may hurt yourself in your confusion by depriving yourself of occasional exposure to difficult problems.1 If you don't occasionally try IMO3 level problems with real conviction, then you will never get to a point of actually being able to solve them.2 For these purposes, paradoxically, it's often better to not know the problem is hard, so you do not automatically adopt a defeatist attitude. -
Notes on the Calendar and the Almanac
1914.] Notes on Calendar and Almanac. 11 NOTES ON THE CALENDAR AND THE ALMANAC. BY GEORGE EMERY LITTLEFIELD. In answering the question, why do the officers of pub- he libraries and bibliophiles so highly esteem and strive to make collections of old calendars and almanacs, it may be said that the calendar was coeval with and had a great influence upon civilization. Indeed, the slow but gradual formation of what we know as a calendar is an excellent illustration of the progress of civilization. At first it was a very crude scheme for recording the passing of time, deduced from irregular observations of the rising and setting of a few fixed stars, by a people who had but recently emerged from barbarism. The resultant table was of very little value and required constant revision and correction. It was only by long and patient study and observation, by gaining knowledge from repeated failures, that finally was produced the accurate and scientific register, which today bears the name of calendar. Furthermore, the material and shape of the tablet upon which the calendar was engraved or printed, was a constant .temptation to artists to decorate it with pen- cil or brush, which caused it to become a valuable me- dium for inculcating in the minds of the people, ideas of the sublime and beautiful, and never more so than at the present time. As regards the almanac, it also is of ancient memory, as we have positive evidence of its existence more than twelve hundred years before the Christian era. To its compilation scientists, philosophers, theologians, poets 12 American Antiquarian Sodety. -
Report of Time and Frequency Activities at NICT
CCTF/12-07 Report of Time and Frequency Activities at NICT National Institute of Information and Communications Technology Koganei, Tokyo, Japan 1. Introduction The National Institute of Information and Communications Technology (NICT), an incorporated administrative agency, was established in 2004 with its large part inherited from the Communications Research Laboratory (CRL). The activity of time and frequency standards is conducted within the Space-Time Standards Laboratory of the Applied Electromagnetic Research Institute, this group itself comprises of four groups as follows. Firstly, the Atomic Frequency Standards Group develops atomic clocks ranging in frequencies from microwave to the optical region. Specifically, Cs fountain primary frequency standards, a single Ca+ ion trap optical clock and a Sr optical lattice clock are originally developed. In addition, research in THz frequency standards has recently begun. The second group is the Japan Standard Time Group, which is responsible for generation of Japan Standard Time, its dissemination, and a frequency calibration service as a national authority. Thirdly, the Space-Time Measurement Group at Koganei develops precise time and frequency transfer techniques using optical fiber and satellite links. Lastly, the Space-Time Measurement Group at Kashima specializes in VLBI research using a 34 m antenna, and has recently begun research into VLBI precision time transfer. Details of these activities are described in the following sections. 2. Primary clocks NICT has been developing Cs atomic fountain frequency standards for contribution to the determination of TAI, and are also used in frequency calibration of Japan standard time and calibration of optical frequency standards. The first fountain (NICT-CsF1) has been in operation since 2006 and accuracy evaluations with CsF1 have been carried out a few times per year. -
