Paris_Example

Been working through the actual math of using a formula on a sphere

to solve a daylight hours problem. Using Paris, France as the example.

Paris sits at Latitude 48.9 degrees N and Longitude 2.2 degrees E.


                                                             





Calculating for the Summer Solciste ie, longest day of the year...

https://share.gemini.google/6GfkuFKVc0r9


My calculations:

tan(48.9) = 1.146
tan(23.5) = 0.434

1.146 x 0.434  = 0.497

I want to calculate arccos(0.497) - (arccos is the angle for a given arc length) - but my 

Windows machine will only do this if I am working in rads...

(There are 2 pi rads in 180 degrees.)

arccos(0.497) is 1.05 rads.

pi - 1.5 is 2.09 rads

Or more directly, I run arccos on -0.497:

(minus because the tilt is giving me more hours!... while the numbers run counter clockwise on the sphere!))

                                                                             


To get hours, I divide 24 hours by pi rads.

I then multiply by 2.09, which gives 15.9 hours.

                                                                    


I am free to add more minutes, as per the Gemini solution!

Context_on_Calcs

With respect of Montreal and Edmonton longitude calculations...

Copilot:

Does this formula assume the Earth is a sphere?

Yes. The standard formula I showed assumes the Earth is a perfect sphere.

In reality, the Earth is slightly flattened at the poles and bulges at the equator, making it an oblate spheroid. The equatorial radius is about 21 km larger than the polar radius.

For sunrise and sunset calculations, however, the spherical assumption works remarkably well because:

The Earth's radius is about 6,371 km.

The flattening is only about 0.3%.

The resulting error in sunrise or sunset times is typically much smaller than other effects, such as atmospheric refraction.

In fact, the largest source of uncertainty is often the atmosphere. Variations in temperature and pressure can shift the apparent sunrise or sunset by a minute or more because they cange how strongly light bends near the horizon.

Modern astronomical software therefore includes corrections for:

Earth's actual shape,

atmospheric refraction,

observer elevation,

the Sun's finite size,

and the precise Earth-Sun geometry on a given date.

An interesting consequence is that if you stand on a hill or in a tall building, you can see the Sun for longer than someone at sea level because your horizon is farther away. From the top of a 100 m hill, sunrise occurs about a minute earlier and sunset about a minute later than at sea level.

For a place like St-Jean-sur-Richelieu (about 45°N), treating the Earth as a sphere gives sunrise and sunset times that are extremely close to the values published by weather services. The atmosphere usually matters more than the Earth's slight flattening.

In a sense, the spherical model is to astronomers what a straight line is to engineers: not perfectly true, but often accurate enough to get very useful answers.

Copilot:

The amount of daylight is determined almost entirely by which ring (latitude) you're on, not which slice (longitude) you're on.

So when comparing:
Saint‑Jean‑sur‑Richelieu: 45°N, 73°W
Port‑au‑Prince: 18°N, 72°W
Bogotá: 4.7°N, 74°W

you're holding longitude nearly constant and changing mainly latitude. That's why the daylight changes from:

about 8¾ to 15½ hours in Saint‑Jean,
to roughly 11¼ to 13 hours in the Caribbean,
to almost exactly 12 hours all year in Bogotá.

 The roofers are here, with very large and impressive equipment.

They are starting at my end of the building, and I am on the top floor.

The old roof is being torn off and it is dramatic. All this to say  I will share the 

main reference points for the math I was planning to blog about today but

leave the discussion for tomorrow. No puttering around the place for me today!


Yesterday I looked at Longitude, the East/West position of Montreal  and Edmonton,

 Alberta.

360 degrees, divided over 24 hours, gives 15 degrees. So knowing the Longitude 

of both cities allows us to see they are 2 hours and 40 minutes apart. 


But to discuss patterns of enlightenment, we need Latitude, the North/South component. 

And that is more complicated because the great sphere that represents Earth is itself 

bent by 23 degrees and its position with respect to the Sun changes with time of the 

year and time of day.

 French politics; from the Left...

Time_Change

Just changed all the clocks in the appartment, including my watch. The

new Quebec government has said we are doing this for the last time. They are going 

to let a panel of experts advise on what time system we should be going to.

If health experts decide, I would expect standard time. If it is a popular choice,

it might be Daylight Savings. Ontario would like to align with Manitoba to go

with Daylight, but is waiting for Quebec and New York State...


Copilot:

Has New York State indicated what it would like on this matter?

Yes. The general position of New York State has been quite similar to Ontario's: many state legislators have expressed support for permanent daylight saving time (keeping the "summer" clock year-round and eliminating the twice-yearly clock changes). However, New York has not actually made the change and continues to observe the normal daylight-saving schedule.

In fact, New York has considered legislation that would allow permanent daylight saving time if federal law permits it. One such bill, Senate Bill 3380, was still pending as of 2026

The complication is that U.S. federal law plays a role. States can opt out of daylight saving time entirely and stay on standard time year-round (as Arizona and Hawaii largely do), but a state generally cannot switch unilaterally to permanent daylight saving time without a change in federal law.

This is why Ontario has been watching developments south of the border. If New York were able to move to permanent daylight saving time, Ontario would be much more likely to activate its own legislation so that Toronto, Ottawa, Montreal, and New York City remained aligned.

An interesting wrinkle is that not everyone agrees on which permanent time is best:

Permanent daylight saving time means more evening light in winter.

Permanent standard time means earlier sunrises in winter.

For places as far north as southern Ontario, Quebec, and New York, permanent daylight saving time would push some winter sunrises quite late. In New York City, for example, the latest winter sunrise would be about 8:20 a.m. under permanent daylight saving time.

So, to answer your question succinctly: New York's political discussion has generally leaned toward permanent daylight saving time rather than permanent standard time, but neither New York nor the U.S. federal government has yet completed the legal changes needed to make that happen.


Didn't the original move to Daylight originatein the US? Are the countries elsewhere than North America that use it?

No, the original idea did not originate in the United States.

The history is a bit surprising:

In 1784, Benjamin Franklin (while in Paris) wrote a humorous essay suggesting people could save candles by getting up earlier. He did not propose changing the clocks.

In 1895, George Hudson, a New Zealand entomologist, made one of the first serious proposals for a seasonal clock change.

In 1907, British builder William Willett became a prominent advocate of the idea in the United Kingdom.

The first country to adopt daylight saving time nationally was Germany (with Austria-Hungary) during the First World War in 1916, largely to conserve fuel and electricity. Britain followed shortly afterward, and the United States adopted it in 1918.

As for the rest of the world, yes, daylight saving time is used well beyond North America, though not nearly as widely as many people think.

Today it is mainly concentrated in:

Most of Europe (including France, Germany, Spain, Italy, the UK, etc.)

The United States and most of Canada

Parts of Australia and New Zealand

A few countries in the Middle East, such as Israel and Lebanon.

Chile and some other jurisdictions in South America.

What is perhaps more interesting is that most of the world does not use daylight saving time at all. Most of Asia, most of Africa, and many countries in South America either never adopted it or abandoned it. Countries near the equator have little reason to use it because daylight hours change very little over the year.

In fact, the long-term trend has been away from clock changes. Countries such as Russia (2014), Brazil (2019), and much of Mexico (2022) have abolished daylight saving time.

One irony is that while many Canadians think of the spring and autumn clock changes as a universal practice, they're actually a feature mainly of the mid-latitude industrialized countries of Europe and North America. Most people on Earth never change their clocks at all.


But both Britain and France switch during the year?

Yes. Both Britain and France still switch their clocks twice a year.

In the United Kingdom, clocks move forward by one hour in spring (to British Summer Time, BST) and back in autumn (to Greenwich Mean Time, GMT).

In France, clocks move forward from Central European Time (CET) to Central European Summer Time (CEST) in spring and back in autumn.

An interesting point is that the UK and France make the change on the same dates, so France remains one hour ahead of Britain throughout the year.

The European Union discussed abolishing the clock changes several years ago. The European Parliament voted in favour of ending them, but the proposal stalled because countries could not agree on whether to keep permanent summer time or permanent standard time. As a result, the twice-yearly clock changes remain in place across most of Europe.

For someone in Québec, the surprising thing is that France changes its clocks on almost the same schedule as we do, despite being an ocean away. When Québec "falls back" in late autumn, France and Britain do too, although not always on exactly the same weekend.

In fact, if you've ever travelled to France in winter, you've experienced something slightly odd: Paris is much farther north than Montréal, yet because of France's time zone and daylight-saving arrangements, winter sunsets can occur surprisingly late by European standards. That is one reason the debate over permanent summer time versus permanent standard time remains lively in both France and Britain.

                                                                  *     *     *

So here we are: Alberta and Quebec are three hours apart in physical terms (2 hours and 40

minutes), but currently clocking in at two in the summer and one in the winter:

Time zones in Canada are getting complicated. These maps lay them out | CBC News

                                                                  *     *     *

On a personnal note, the body has its own way of adapting to things.

In my older years, I have set fixed rules for myself, and one has to do with

breakfast time. I can have hot drinks when I get up, but breakfast is no sooner

than 10 AM. So that during Daylight Savings Time periods, I can eat at 9 AM Standard.

But guess what, in the Fall I am not hungry at 10 AM, or am too busy to notice.

Lately, I have been eating fruit and dry toast around 11 AM Daylight. Which is 10 AM

Standard. So my body has been gradually keeping up with my 10 AM rule and I am

marginally hungrier into the winter months!!

Has New York State indicated what it would like on this matter?

Yes. The general position of New York State has been quite similar to Ontario's: many state legislators have expressed support for permanent daylight saving time (keeping the "summer" clock year-round and eliminating the twice-yearly clock changes). However, New York has not actually made the change and continues to observe the normal daylight-saving schedule.

In fact, New York has considered legislation that would allow permanent daylight saving time if federal law permits it. One such bill, Senate Bill 3380, was still pending as of 2026.

For places as far north as southern Ontario, Quebec, and New York, permanent daylight saving time would push some winter sunrises quite late. In New York City, for example, the latest winter sunrise would be about 8:20 a.m. under permanent daylight saving time.

Cake

Made a cake for Halloween. something I haven't done in a while. It

looks a tad weird and it is: I had no instant coffee so put in actual coffee

in the chocolate layer, which was then more liquid than the other... see

the result below. But it tastes great, isn't too caloric and it is festive.

I also didn't have chocolate chips for the topping, but have been eating it

with fruit and yogurt and chomping on chocolate candy now and again.

Markets...

 So is Canada the sleazy one, signing an accord with the EU just as

things migt be picking up again on a deal with the US. Because one cannot

really have both going at the same time. If one did, one could just buy things in 

one market, and sell them in another: for example, I buy up pumpkins from the US

and sell maple syrup with pumpkin in Paris, and all the while the US pumkin

farmer can only sell with tariffs attached in that market. Hooooo!


Looking at our other commitments was just one thing Team Canada woudn't let

the US do. Or maybe this wasn't a totally innocent request. In any event, we do

appear to be making a choice for the EU...

HAPPY HALLOWEEN TO ALL!

HAZARDOUS

 Chilbirth is truly hazardous...

Us_Academia

 Was reading this morning how Jon Ossoff was a coming star in the US

Democratic party. But consulting his bio in Wikipedia did leave me with a question:

https://share.gemini.google/6OhLzQ2YROue

                                         *     *     *

Copilot:

'Ossoff is a 2009 graduate of Georgetown University's Walsh School of Foreign Service with a Bachelor of Science in culture and politics.' Read this description of a US Senator's biography on Wikipedia and it seems odd to me. How can one have a science degree in culture??

It does sound odd at first glance, but in the U.S. university system the phrase "Bachelor of Science" (B.S.) does not necessarily mean the subject itself is a natural science like physics, chemistry, or biology.

There are two separate things here:

The degree type: Bachelor of Science (B.S.) versus Bachelor of Arts (B.A.).

The major: Culture and Politics.

At many American universities, a social-science or interdisciplinary programme may award a B.S. even though its subject matter involves culture, politics, economics, international relations, or public policy rather than laboratory science.

In Ossoff's case, the Walsh School of Foreign Service at Georgetown is a specialised school focused on international affairs. "Culture and Politics" is an interdisciplinary major that examines questions such as:

How culture influences political behaviour.

Nationalism and identity.

Religion and politics.

Ethnic conflict.

Globalisation and cultural change.

International relations viewed through historical and social-science lenses.

The "science" part of the degree usually refers to the programme's emphasis on systematic analysis, research methods, social-science theory, statistics, economics, and empirical study, not test tubes and microscopes.

A rough analogy would be:

B.Sc. in Economics: common, even though economics is not a natural science.

B.Sc. in Psychology: also common, despite studying human behaviour.

B.Sc. in Culture and Politics: less common, but based on the same idea.

In fact, many subjects sit in a grey zone. Political scientists, economists, sociologists, and psychologists often use scientific methods (hypothesis testing, statistical analysis, surveys, modelling), which is why universities sometimes classify them as sciences.

So the wording is not saying that culture itself is a science. Rather, it means Ossoff completed a programme called Culture and Politics and Georgetown chose to award that programme as a Bachelor of Science degree.

Your reaction is shared by many Europeans and Canadians, because North American universities can be surprisingly liberal in how they use the B.A./B.S. distinction. In some cases, two students studying nearly the same material at different universities may graduate with different degree titles simply because of institutional tradition.


Are there universities in Canada that make this distinction?

Yes, although generally Canadian universities tend to be a bit more conservative than American ones in their degree titles.

For example, at Concordia University, Political Science is offered as a Bachelor of Arts (B.A.), not a B.Sc. Likewise, the University of Waterloo awards a Bachelor of Arts in Political Science.

That said, Canada definitely has programmes where social-science subjects receive science-oriented degrees:

Psychology can be taken as a B.Sc. at McGill.

McGill also offers interdisciplinary B.A. & Sc. degrees that combine Arts and Science approaches, including Political Science and Psychology.

The deeper issue is that the distinction between B.A. and B.Sc. is often historical and administrative rather than philosophical.

A political science department might award:

a B.A. if it emphasizes history, political theory, and qualitative analysis;

a B.Sc. if it emphasizes statistics, formal modelling, economics, polling, and quantitative research methods.

Indeed, if you look at modern political science journals, much of the work involves statistics, survey design, econometrics, and data analysis. Some political scientists spend more time with datasets than historians do with archives.

Your reaction may also reflect an older understanding of the word science. In French and in much of Europe, science is often understood primarily as the natural sciences. In the English-speaking academic world, however, universities commonly speak of the social sciences: economics, political science, sociology, psychology, anthropology, and so on.

So a Canadian degree called"B.Sc. in Culture and Politics" would still be unusual, but not absurd. The more typical Canadian label would probably be B.A. in Culture and Politics, whereas an American institution such as Georgetown is somewhat more willing to attach a B.S. designation to an interdisciplinary social-science programme.

Interestingly, the very name "political science" dates from the 19th century, when scholars hoped that the study of government could become as systematic and evidence-based as the natural sciences. Whether they fully succeeded is still a matter of debate!


I think it had to do with the practice of publishing journals in a particular field...

You've put your finger on an important historical point.

The term "science" originally had a much broader meaning than it commonly does today. It comes from the Latin scientia, meaning simply "knowledge." For centuries, a science was essentially any organised body of knowledge.

One reason disciplines fought to be recognized as sciences was indeed the emergence of the modern research university and scholarly journals in the 19th century. Fields such as economics, sociology, political science, and psychology sought to establish themselves as rigorous academic disciplines by:

founding professional associations;

creating peer-reviewed journals;

developing specialised research methods;

collecting data systematically;

building theories that could be tested and criticized.

Political science, for example, wasn't merely the study of politics in the old sense of reading philosophers like Plato or Locke. Scholars wanted to study voting, institutions, revolutions, public opinion, and government behaviour in a way that resembled the growing prestige of the natural sciences.

This is why many academic disciplines acquired names ending in "-ology" or incorporated "science" into their titles. The label signalled: "We aren't just discussing ideas; we're conducting research according to recognised methods."

That said, there has always been a debate. Critics argue that human beings, cultures, and societies do not behave with the predictability of atoms or planets, so the social sciences can never be sciences in quite the same sense as physics or chemistry. Supporters reply that even if human behaviour is more complex, it can still be studied systematically and empirically.

Your observation about journals is especially relevant because, in academia, a field often gains legitimacy when it develops:

a research community,

specialised journals,

recognised methodologies,

standards of evidence.

In many ways, those institutions matter more than the degree title itself. A "Culture and Politics" programme is considered an academic discipline not because it studies culture, but because there is a community of scholars producing and evaluating research about culture and politics through journals, conferences, and peer review.

So when you see "Bachelor of Science in Culture and Politics," you're really seeing the outcome of a long academic tradition that says: culture and politics can be studied using scholarly methods, whether or not you personally feel that makes them "science" in the same sense as chemistry. Many academics themselves still debate that question.

Is there a lot of homelessness in Canada. I would think the climate would work against this...

Yes. In fact, many Canadians are surprised at how much homelessness exists given the climate.

Recent federal data indicate that about 119,600 people used an emergency homeless shelter at some point during 2024, roughly the same level as before the pandemic. On an average night in 2024, about 19,300 people were staying in shelters, and shelter occupancy was very high at about 88%.

A separate national count found that tens of thousands of people were homeless on a single night across participating communities in 2024, including people in shelters, transitional housing, and living outdoors.

As for the climate, your intuition is sensible: Canadian winters do make street homelessness more dangerous than in warmer countries. But several factors offset that:

Emergency shelters provide winter accommodation for many people.

Some people live in encampments, vehicles, abandoned buildings, or temporary indoor spaces.

There is a significant amount of"hidden homelessness": people sleeping on friends' couches, staying with relatives, or moving from place to place. These people are often not visible on the street and are not always counted.

In recent years, housing costs and rents have risen faster than incomes in many cities, pushing more people into housing insecurity.

Interestingly, winter does not eliminate homelessness; it tends to change where and how people survive. In cities such as Montréal, Toronto, Vancouver, Edmonton, and Calgary, shelters often become extremely crowded during cold weather, and outreach teams work actively to prevent deaths from exposure.

In Québec, homelessness has become much more visible over the last decade, particularly in Montréal, and concerns about homelessness are now common in many medium-sized cities as well. That helps explain why it has become a major political issue, including in the article you're currently reading about homelessness policy in Québec.

One historical note: Canada actually had visible homelessness even in the 1930s Depression and in earlier periods. Cold weather makes homelessness harder, but unfortunately it has never been enough by itself to prevent it.
