From the Packsacks of a Computer Science Teacher in Northern Canada
=== by Bob Sutherland ===
Hello and welcome. I am a retired Computer Science teacher who wandered away from the big city high schools to spend most of my career living and teaching in northern Canadian communities. Like many teachers I had a tendency to collect things that I thought might be useful in my classroom when teaching someday. Over the years my assortment grew quite diverse partially because some school principals did not hesitate when assigning me to teach just about anything. This website contains a collection of web pages that I have created from various things I accumulated in my packsacks. I hope you find something interesting or useful here.
This is a collection of number lists, conversion charts and math review notes for topics I have taught in Math, Science and Computer classrooms. Included are Roman Numerals; binary, octal and hexadecimal numbers; base 26 Alphabet numbers; base 32, base 60 and base 64 numbers; numbers squared; numbers cubed; and some exponent lists that include powers of 2, 8, 16, 26, 32, 60 and 64.
This is a collection of conversion charts for temperature, distance, weight and liquid measurements. Included are Fahreheit, Celsius and Kelvin; inches, feet, yards, centimetres and metres; miles, nautical miles and kilometres; pounds and kilograms; Imperial gallons, U.S.A. liquid gallons and litres.
This is primarily a collection of Canadian military photographs taken in Belgium and France during World War I and the D-Day invasion of World War II. The collection includes photographs of some memorials, parks and cemeteries in France and Belgium that honour the sacrifice of the Canadian soldiers.
I cannot think about teaching all of the time. Here are a few off-topic web pages that have I created when distracted by other thoughts. This section of my website is beginning to resemble the sort of files I would discover students and staff had created on the computers in my computer labs.
What happens to vehicles when the temperature drops to -40 degrees Celsius? The simple answer is they freeze, break and tend not to work. During my teaching career I have driven three pickup sized trucks that I have owned into subarctic communities. I have then tried to keep them operational throughout the winter as temperatures sometimes dropped below -40 degrees Celsius. Here is a description of my experiences.
On this page you will find definitions of e.g., i.e., etc., et al, informal versus formal writing style, Latin Quarter and a few other things that I usually teach my students during the first week of school in my courses.
Having named my website after a very cold temperature it only seems fitting that I should devote a page of my website to information about thermometers, temperature, weather, climate, wind chill, frostnip, frostbite, meteorology, climatology, global warming and -40 degrees.
Modern Measuring Units for Computer Memory
A listing of the four different charts of computer memory unit sizes that standardization committees have created. Many companies are now using one of these four charts. You just have to figure out which chart a particular company is using under what circumstances.
Computer Fonts for Web Pages
The following three web pages summarize my research as I was trying to select fonts for my web site.
